AN ENGINEER’S VIEW

Load Shedding and School Holidays

I

t’s school holidays and my children are at home.

And they are bored. I suppose every generation stares in awe at their children who cannot see or comprehend the privileges they enjoy. I may as well “own” their boredom since I have through much grace and hard work, been able to put them exactly in this position. I’d like to come back to that analogy in a minute.

With the recent bout of load shedding – despite any previous events, I was again caught off guard.

No torches (with batteries) nor a generator. At least we have a gas stove, but we struggled to find the igniter. You may have a similar story.

There is a connection between my children who are bored despite having broadband internet, Lego etc, and my unprepared state for load shedding. That is of course: privilege. Not the politically loaded “privilege,” but the fact that engineers are working and succeeding (to a degree) to keep the power on.

The privilege is being oblivious to the facts – being able to go about your business without having to worry about that as well.

End of innocence

While it is unclear where South Africa’s infrastructure is heading, this may be our childhood end. We are all aware of the fact that things are not as steady as we once believed. There is a lighter counterpoint in that engineers may just have gotten their “We told you so!” moment. Engineering, maintenance and the related procurement systems are now in the spotlight. We can be of critical value if we are able to put forward informed alternatives and opinions.

Gideon van den Berg

The catch is that apart from your MSAIMechE neighbours and relatives who will take your advice on quotes for solar panels, geysers, generators with automatic changeover switches etc, your activism will not take you very far. You will need a platform and leverage for your campaign.

Actually, you already have those things at your disposal – your local SAIMechE Committee! Through your committee, it is really just two steps to pretty much anyone within ECSA or any other VA or collection of VAs.

Make sure that you are informed – and then be very opinionated! And go make some waves at your local branch Politics and the public can be influenced, if we manage ourselves as a trusted source of guidance and information. That is exactly what we were trained to do, but I don’t think we are stepping up to the plate like we should.

The take-away is this: make sure that you are informed – and then be very opinionated! And go make some waves at your local branch.

PRODUCTION

Digital Inclination Measurement The latest digital protractors not only measure degrees of incline, whether or not a particular surface is level, but also its precise degree. “What this means is that a particular degree can be preset, and the surface levelled precisely in accordance with the measurements,” says Upat National Product Specialist, Charl Weber.

T

he main difference between the Tech 500 DP and the Tech 1000 DP models is that the Tech 500 DP measures from 0° to 90° and 90° to 0°, while the Tech 1000 DP covers 360°. The former reveals what is out of sync, while the latter calculates the exact amount.

Upat National Product Specialist, Charl Weber

In addition, the latter features smart data transmission to peripheral devices, featuring a RS-485 interface with a Modbus documentation protocol and Stabila Analytics software for analysis. It includes a USB data cable with an M12 connector and a four-pin data cable with M12 connectors.

This makes the Tech 1000 DP particularly well-suited to the automotive industry, where for example, it can be used to align radar systems on new motor vehicles. Upat has already secured a few pre-orders from major automotive manufacturers, Charl reveals.

Applications

The latest digital protractors from Stabila make for easy measurement and alignment tasks in a broad range of applications. The Tech 500 DP is ideal for production applications such as carrying out maintenance on or setting machines.

Long-term measurements are also possible thanks to a range of mounting options. These include a T-groove and a V-groove, plus an integrated rare earth magnet. The Tech 500 DP can also measure key values in quality assurance, while it allows for easy alignment of systems during the commissioning of special-purpose mechanical engineering tasks.

Long-term measurements mean that position changes can be recorded when commissioning a machine, while the actual values measured can be captured in a detailed transfer report The Tech 1000 DP extends the functionality of Stabila’s digital protractor technology by allowing for the modernisation and digitisation of existing machines in production. Advanced features include measuring, recording and documenting key values for quality assurance purposes; as when carrying out maintenance, setting machines, and monitoring processes. Long-term measurements mean that position changes can be recorded when commissioning a machine, while the actual values measured can be captured in a detailed transfer report.

Accuracy

A digital display screen allows for optimum readability under all conditions, while the anodised aluminium measuring surfaces themselves are particularly hardy. These digital protractors are water- and dust-proof in accordance with protection class IP65. A variable power supply includes the option of an integrated lithium-ion battery.

“Precision measurement is fundamental to a range of production work. Hence it is vital that professionals are able to rely completely on the accuracy of their measuring tools.

This calls for measurement technology that is robust, always accurate and easy-to-use,” Charl concludes.

The Stabila TECH 1000 DP features smart data transmission, with a RS-485 interface

Retrofitting is an excellent alternative to buying a new product and can be performed on pumps regardless of their intended use.

KSB Pumps and Valves is leading the way with its range of services that assist users in getting the most out of their pumps when pumping requirements change or to prolong the life of existing pumps.

According to the company’s regional sales manager for Sub-Saharan Africa, David Jones, retrofitting is equally suitable for industrial, water supply and waste water disposal applications as well as for the power supply industry.

Changing requirements

“Changed circumstances often require a new approach.

This also applies to pumps which are used in fluid transfer systems where increased energy efficiency is required to meet new legal requirements, as this does not always necessitate a new pump.

“The areas of use for retrofit solutions are as diverse as the requirements to be met by the pump systems in question. As a result, retrofit solutions go together with hydraulic and mechanical modifications as well as with changes to the materials.

“There are a number of benefits that can be applied to lower maintenance costs, reduce power consumption, achieve longer service life, increase system availability or even to comply with legal requirements,” says David.

Solving premature wear

In others, retrofits because of changing materials or chemicals can solve premature wear or chemical corrosion, while pumps in power stations may be critical and require retrofits to prolong their lives without the need to manufacture purpose-built pumps with potentially long lead times. With expertise to retrofit almost any pump, specify, manufacture and optimise designs, materials, impellers, diffusers etc, and carry-out hydraulic performance tests, it makes sense to consider retrofitting rather than replacing pumps.

ENVIRONMENT

Using Biomass Fuels For Power John Thompson has developed and introduced the Torripac, a biomass-fired package boiler.

A

hybrid boiler containing some watertube boiler features and a range of enhanced package boiler features, the Torripac has significant advantages over other biomassfired package boilers on offer. Such advantages include a modular design, the ability to handle a range of biomass fuels, an enhanced thermal efficiency and the ability to generate power through high pressure steam.

“The development of the Torripac was driven by the increasing demand from our customers to use biomass to generate thermal energy, either by using their own process’s biomass by-product or through purchased biomass in order to reduce their carbon footprint,” says Simon Boiskin, John Thompson’s Export Sales Manager for Package Boilers.

Great foul fuel handler

A variety of fuels can be fed into the boiler through

its box-ram feeding system, while the vibrating grate combustion system is proven to handle fouling fuels better than traditional methods. In addition, the watertube furnace incorporated in the Torripac is designed to have a low exit combustion gas temperature which further reduces the risk of fouling.

A packaged heat recovery tower which includes a two or three pass tubular air-heater, in combination with an economiser enhances the thermal efficiency of the unit.

Reusing gases

“The air-heater and economiser extract heat from the combustion gas that would otherwise have exited the chimney unused. This heat is used in the air-heater to preheat the combustion air and in the economiser to preheat the feedwater. The air-heater preheats the combustion air to dry and combust fuels with up to 50 % moisture,” explains Etienne de Villiers, John Thompson’s Divisional Technical Manager.

The Torripac’s high operating pressure of 29 bar versus the industry standard of 10 bar allows the option of generating electrical power in conjunction with process steam. Power can be generated by passing the high pressure steam through a back pressure power generating unit such as a steam turbine or a screw expander unit. In this way electricity is generated by the high pressure steam while steam is reduced to the customer’s required process pressure.

LABOUR MANAGEMENT FABRICATION

The Undercover Investigator Many businesses focus their loss control strategies on preventing unwanted elements from getting in from the outside. While this is certainly an important step in securing assets and minimising risk, what if the truly dangerous element has already made itself comfortable within the operations of the organisation?

I

n financial management, internal audits play an integral role in ensuring the financial stability and integrity of the organisation. Similarly, savvy businesses should expose themselves to an internal auditor of a different kind – the undercover investigator.

Businesses should expose themselves to an internal auditor of a different kind – the undercover investigator “If conducted correctly, these investigations become the cornerstone of the loss control portfolio,” advises Kyle Condon, Managing Director of D&K Management Consultants. “The successful deployment of well-trained and experienced undercover agents is the single most effective company security tactic.”

Manage risk from inside out

To Kyle, the undercover investigator serves to manage risk from the inside out, in a consistent manner. “The innermost workings of the business can be seen as the core of an onion. While the outer layers of security prevent threats from getting in, the investigator placed at the centre of the operations ensures that those already at the core are not putting the business at risk.”

Undercover investigators are not only useful for theft or loss investigations but also offer Kyle Condon

valuable insights as deployed auditors. “Undercover investigation services are a fantastic way to identify weaknesses in company policies and operating procedures. If these policies are not ‘audited’, chances are that you may not ever know where the real issues lie. With a consistent presence, the investigator continues to protect the business in real-time, rather than reviewing what went wrong after the fact. This creates a proactive loss control strategy,” he adds.

In addition to risk mitigation, undercover investigations offer various advantages. From the development of accurate security budgets and strategies (including elements such as cameras, manpower, policies and procedures, employment processes etc), to the identification of wasted resources, or unethical employees. Having an agent on its payroll gives the business access to essential security and operational information.

Undercover investigation services should be introduced into the client’s workforce. Investigators are deployed as everyday workers or contractors, as would be the case for clients’ routine recruiting procedures. Within a short space of time, the right investigator would have integrated him/ herself among the rest of the employees.

Undercover investigator tips

Kyle provides four key tips for ensuring the undercover investigator remains impartial and effective: “Rotate the investigator every six months. Place them in different sectors or departments to get a full view of the business’ operations. Place them strategically to combat crime, taking the guessing out of the game. Use the intel they provide to assist in creating accurate and impactful policies and procedures.”

While the undercover investigation services are in progress, information is passed on to the client directly. This should happen on a weekly basis.

“The weekly reports enable the investigation firm to formulate graphs and provide analytics that will clearly show trends and patterns of the various associated risks,” concludes Kyle.

CONFERENCING

Building Sustainability Through Local Manufacturing There is enormous potential for Southern African manufacturers to increase their market share both locally and internationally. The driving force behind capturing this growth opportunity is the South African Capital Equipment Export Council (SACEEC).

A

ccording to Eric Bruggeman, CEO at SACEEC, part of the Council’s mandate is to organise outward selling and inward buying missions. “We identified a need to showcase the offerings of the SADC region’s local manufacturers in an interactive manner.

The result is the inaugural Local Southern African Manufacturing Expo (LME) being held at the Expo Centre, Nasrec from 21 to 23 May 2019,” he says.

Eric Bruggeman, CEO of SACEEC

Grow a customer base

“It is critical for the sustainability of local manufacturing operations that they aggressively pursue opportunities to increase their market share. Not only is this relevant to their increased permeation

of the overseas market, but furthermore, they need to capture market share that is currently being monopolised by importers.

Recent statistics indicate that South Africa currently imports products to the value of a staggering $83.2-billion. If we were able to shift this demand to the local manufacturing sector, we could realistically create 1.329-million jobs,” adds Eric.

Recent statistics indicate that South Africa currently imports products to the value of a staggering $83.2-billion “We believe that the exhibition will enable exhibitors to meet with top decision makers from the inward buying missions already committed to the event.

“As Industry 4.0 continues to transform the way that manufacturers do business, LME 2019 will provide them with an opportunity to grow their customer base, with the knock-on potential for fostering job creation,” says Charlene Hefer, portfolio director for Specialised Exhibitions Montgomery.

High Temperature Servicing With Air Cannons Martin Engineering has announced a new technology for installing air cannons without a processing shutdown. The system allows technicians to mount the units on furnaces, preheaters, clinker coolers and in other high-temperature locations while production continues.

With all installation and service performed from outside the vessel or process, the system also contributes to a safer workplace by minimising the difficulty and hazards of installation and maintenance.

T

he company developed the Martin Core Gate to reduce expensive downtime associated with traditional installation methods, which require that high-heat processes be halted to allow core drilling and mounting of the cannons.

The new system has been paired successfully with the firm’s Smart Nozzle Series, a family of air cannon nozzle designs which can be serviced or replaced during production, without removing the

In the past, when material accumulation problems became an issue, processors would have to either limp along until the next scheduled shutdown or endure expensive downtime to install an air cannon network

Saving money

“In the past, when material accumulation problems became an issue, processors would have to either limp along until the next scheduled shutdown or endure expensive downtime to install an air cannon network, costing hundreds of thousands in lost production,” says Global Flow Aids Manager, Brad Pronschinske “Our initial advancement was engineering a nozzle design that could be safely replaced with no production stoppage,” Brad continues. “Now this technology allows us to add air cannons and nozzles to an operation while it’s in full swing, without disrupting the process.”

To install air cannons in a running process, Martin technicians first conduct a thorough assessment of the accumulation patterns and blockages to identify

The drill cuts through outer wall and refractory, then retracts automatically

the proper air cannon locations, then drill through the outer wall and weld the Core Gate in place.

The core drill is mounted, checked for alignment and started, with progress monitored from a safe distance as it works its way through the refractory.

As soon as the drill cuts through the refractory, the drill is backed out and an isolation shield is slid into place to protect workers from the severe environment. The Smart Nozzle assembly is mounted next, using an 8-bolt pattern that delivers excellent support, followed by the nozzle itself.

Our initial advancement was engineering a nozzle design that could be safely replaced with no production stoppage Leaving the refractory intact

Replacing a conventional fan nozzle on existing equipment typically requires the removal of refractory material from around the nozzle opening, usually with a pneumatic hammer from inside the vessel.

The process invariably weakens the surrounding refractory and renders it more susceptible to spiderwebbing and subsequent cracking. In contrast, the Martin replacement system leaves the refractory undisturbed during service, and one worker can safely perform installations or maintenance from outside the vessel.

TECHNOLOGY

The Digital Culture Challenge When it comes to digital transformation, people matter every bit as much as technology, says Victoria van Camp, CTO and president of innovation and business development at SKF

R

egardless of their sector, size or history, companies are recognising that the recent improvements in connectivity, control and analytical capabilities have the potential to unlock improvements in the cost, quality and productivity of their operations. More fundamentally, digital technology is enabling entirely new product and service offerings and underpinning the creation of new business models.

“You don’t have to look far to see this process in action. SKF has been designing and making bearOur engineers couldn’t ings and seals for more create new products than a century. Today however, or solve customer problems we are a without our portfolio of advanced

digital business too,” says Victoria.

“Our engineers couldn’t create new products or solve customer problems without our portfolio of advanced design optimisation and simulation tools.

We have made significant investments in flexible, automated manufacturing sites and connected logistics networks, too.

“Yet despite all the progress made so far, few organisations can claim to have mastered the digitalization challenge. The gap between the potential application of digital technologies and what most companies have integrated into their everyday operations remains wide.”

If the rewards of the digital revolution are so significant, what is holding companies back? Technology is certainly part of the story. Some digital approaches have not yet reached the level of maturity required for large scale use.

Tech adoption more cultural

But there is also something else at play, there are plenty of technologies that are mature, robust and inexpensive capable of being applied far more widely than they are today. This suggests that barriers to adoption are not technical, but cultural. There’s plenty of evidence to support that hypothesis. When consultancy Capgemini Invent surveyed more than 1700 business leaders

April 2019

last year, for example, 62 percent of them said that their own corporate culture was the biggest obstacle to digital transformation.

Perhaps that shouldn’t be surprising. Moving to a digital world can be an unsettling experience. There’s the requirement to work in new ways, with new tools, for example.

In some cases, staff may fear a loss of autonomy. Increased transparency also means there is nowhere to hide if things aren’t going well. Everything becomes much more transparent.

Late adopters

The bad news, according to Capgemini’s research, is that companies in the mechanical and plant engineering sectors are late adopters when it comes to the creation of a true digital culture.

“The discipline of engineering strongly focuses on the technical side of its products and services,” notes Yvette Zzauer of Capgemini Invent.

Few organisations can

“ T h i s claim to have mastered the strongly imdigitalization challenge pacts the corporate culture, which tends to be a more technology than human-centered culture.” While this means engineering businesses tend to be more comfortable than other sectors about adopting technological advances, she adds, it can mean they pay insufficient attention to the human side of digitalisation.

Fortunately, there are things companies can do to actively promote cultural change. In the past, corporate culture was broadly and intangibly defined by shared values, attitudes, standards and beliefs that characterise the members of an organisation and define its nature. However, digital culture is more tangible, concrete and explicit.

Truck Sales Rocket The South African commercial vehicle market got off to a flying start this year, showing a 7.3% increase to 1 653 sales.

T

his is according to the latest results released for January 2019 by the National Association of Automobile Manufacturers of South Africa (Naamsa), Associated Motor Holdings (AMH) and Amalgamated Automobile Distributors (AAD).

Looking at the year-on-year comparison, medium commercial vehicle sales grew by 24.6% to 552 units. Sales in the heavy commercial vehicle segment increased by 6.5% to 327 units, while the extra heavy commercial vehicle showed a slight decline of 1.8% to conclude the month on 719 sales. Bus sales were down by 6.8% to 55 units.

In order to have a healthy and safe vehicle population, trucks need to be replaced every eight to ten years or so “We are very encouraged by the good start to the year,” says Gert Swanepoel, managing director of UD Trucks Southern Africa. “We foresee that certain macroeconomic influencers like the upcoming national elections and lower business confidence might dampen sales up to July.”

Challenging economic conditions

Gert says that 2018’s positive results proved that the truck market is resilient, even amid challenging economic conditions, and that businesses still choose to invest in new vehicles for their fleets.

“One concern is that the average age of the local commercial vehicle is too high, at around 12 years currently. In order to have a healthy and safe vehicle population, trucks need to be replaced every eight to ten years or so,” he continues.

Gert believes that more and more businesses are turning to modern smart logistics to ensure efficiency, productivity and profitability. Aspects like telematics are playing an increasing role in fleet and route planning, as the demand from consumers for faster turnaround times grows.

Kicking off with a soft start The new ADXL soft starter series from Lovato, distributed

by ElectroMechanica (EM), is designed for three-phase motors from 7.5kW to 160kW, in four frame sizes, EM Product Manager, Jaap Grobler explains.

They allow for control of starting, stopping, monitoring, and protection, with integrated functionality for an efficient starting solution.

A wide operational voltage range of 208 V AC to 600 V AC, a compact design, and advanced functionality make the ADXL series an efficient solution for most applications in all industries. Two-phase control during motor starting and stopping, combined with torque control during operation, provides optimised ramping characteristics.

This ensures smooth start and stop functionality for all applications, significantly increasing the lifespan of connected motors and power transmission devices. Hence the ADXL series is an great choice for pumping applications where water hammering is normally a major problem. Kick-start functionality delivers high torque only during the initial starting period, permitting motors to be started when initial torque is insufficient to overcome friction.

The distributorship increases Hytec South Africa’s product and service capabilities and presents new opportunities for distributing non-welded, leak-free piping systems. This is especially the case where projects include design and engineering, as GS-Piping Systems’ assemblies can be prefabricated to a high degree prior to installation, which speeds up the installation process and reduces overall costs.

Outdoor enclosures for harsh environments The harsh environment protection benefits of GRP-based enclosures are now available for hundreds of new outdoor applications with the launch of new Type 4X certified enclosures and cabinets from Intertec.

The company specialises in enclosures for outdoor applications, which are all fabricated using advanced GRP materials. GRP-based Type 4X enclosures are ideal for protecting field-based electrical and instrumentation equipment sited in marine and coastal areas, where the presence of salt in the atmosphere can severely damage traditional metal enclosures and shorten their service life.

The company’s GRP is highly stable and virtually immune to the affects of salt

and most common petrochemicals and airborne pollutants. GRP has a similar strength to stainless steel but is about 75 percent lighter.

Intertec’s Type 4X enclosures also include uniquely efficient insulation thanks to a proprietary triple-layer composite construction that ‘sandwiches’ advanced insulation material between sheets of GRP. This aspect makes these enclosures and cabinets ideal for applications in the harshest of environments and any region or application environment that must deal with difficult conditions involving ultra-cold or -hot temperatures.

Only nine percent of manufacturers to invest in digital Research by InfinityQS has revealed that only nine percent of manufacturers are planning to invest in digital transformation projects over the next 12-18 months.

This was closely followed by 20 percent of manufacturers that have disclosed their plan to invest in waste production solutions over the same period.

Jason Chester, Director of Channel Programs for InfinityQS, says, “The survey results highlight manufacturers’ lack of true understanding surrounding the benefits of digitalisation projects.

According to a survey by PWC, manufacturing companies who embrace the digitalisation drive can expect to reduce operational costs by 3.6 percent per annum while increasing efficiency by 4.1 percent.

“Yet, instead of focusing on digitalisation, manufacturers are prioritising spend elsewhere.

“Waste reduction has been a priority among manufactures for many years, which consequently means any advancements are increasingly becoming even more marginal, delivering fewer returns for

firms. Any progresses in waste reduction lies in digitalisation projects that unlock significant improvements by enabling manufacturers to monitor and respond to the causes of waste more clearly.

“Additionally, almost 50 percent of manufacturers say that they are going to invest in data collection, but that alone

only represents one part of an organisations digital transformation journey. If that investment is being made, it makes economic sense to use that data for manufacturing and quality intelligence,” concludes Jason.

tions, as it features both Ethernet and Profinet communications for seamless interfacing. Other major advantages are precise positioning and ramp-up and ramp-down, and the ability to vary the conveyor speed accordingly, which makes for a highly customisable system.

The latest order follows a demonstration project involving two small conveyors, with one over a production line, to move small components around the assembly area, explains SEW sales representative, Willem Strydom. The automotive manufacturer was so impressed with this initial foray that it has now embarked on a massive seven conveyor, 40 accumulation zone project, which is where the ECDriveS drive system really comes into its own, says Willem.

Sensor input and output is provided for easy monitoring, with an alarm triggered in the event of any problem. The drive system has an IP 54 protection rating, in addition to an IP 66 version

for more demanding applications. The temperature range is –10°C to 40°C, while the roller speed is up to 5m/s.

Gearbox speeds range from 8.5rpm to 645rpm for added flexibility.

Set-up is either by dual in-line package (DIP) switches, or the drive system can be programmed using proprietary SEW software.

Bearings for food Specific to the food and beverage industry, NSK rolling bearings feature attributes like rustproof materials, sealed construction and lifelong lubricants that are compatible with foodstuffs.

To help simplify the bearing choice in such processes, NSK has renewed its catalogue entitled ‘Solutions for the Food and Beverage Industries’. The publication features an overview of the sector and highlights the individual needs of food and beverage processing lines. Core products are also presented.

One of the principal products highlighted is NSK’s Silver-Lube mounted unit series.

Silver-Lube units comprise high-grade stainless steel bearing rings, cage and balls, with seal core and grub screws, grease nipple, and bolt-hole liners.

Further design features include nitrile rubber seals and stainless steel flingers, along with a thermoplastic polyester resin housing. The bearings are factory filled

with a wide temperature foodgrade grease.

Also featured is the LifeLube series of mounted units, which combine the corrosion resistance of a Silver-Lube housing with the sealing and lubricating attributes of Molded-Oil bearings. Of particular importance, Life-Lube bearings are suitable for wet environments, including those that use process fluids and/or chemicals.

NSK’s Molded-Oil bearings are another prominent product. Deployed extensively in food and beverage plants, molded-oil bearings not only prevent the ingress of

contaminants such as water and particulates, but no lubricant can escape the bearing and enter other parts of the machine, where it could contact food.

Protection in explosive environments Organisations which use or deploy mobile PC tablets in volatile environments, where “flammable gases, mists or vapours or combustible dusts are present” must review whether they are compliant with the directive 99/92/EC which relates to minimum requirements for improving the safety and health protection of workers, the directive 94/9/EC which concerns equipment and protective systems intended for use in potentially explosive atmospheres.

They also need to adhere to the North American CID2, which is an ANSI/ISA certification for hazardous locations.

“These regulations address usage of tablets or other electronic devices and are the most widely-accepted safety standards for devices used in hazardous environments where there is risk of explosion,” says Bruno Bothier, Sales Director for Xplore Products at Zebra Technologies

He concludes by saying the organisations operating in explosive environments must demand tablet manufacturers present either an ATEX Declaration of Conformity (DoC) or a C1D2 proof of compliance before buying a rugged device, regardless of where it will be used.
