Servicing Manual Centralized Lubrication System for LIEBHERR Hydraulic Excavator R 9250

Function of the lubrication system

1.1

Description of the entire system: see the diagram under item 1.3

Manual

The lubrication points of the hydraulic excavator are supplied by two mutually independent centralized lubrication systems: ion- Slewing rim lubrication Single-line system Main components:

Hydraulic pump "P1" 609-29333-1 Injectors LM-5, SL-1 Progressive metering devices SSV

Main components:

Hydraulic pump "P2" 644-46265-1-L Progressive metering devices SSV

1.2

Sequence of a lubrication cycle

1.2.1 Systems 1 Upon expiration of the pause time the pump begins operating and supplies the lubricant to the injectors 9 (LM-5, SL-1) via the main line. The pistons in the injectors are actuated by the lubricant under pressure and discharge a pre-dosed quantity of lubricant to the connected lubrication points.

The pressure continues to rise in the main line until the value (220 bar) set at the pressure switch (B69) is reached. The control unit stops the pump and, at the same time, the main line is discharged via the solenoid valve (Y79). The relieved lubricant reaches the pump reservoir via a bypass.

The pistons in the injectors 9 (LM-5, SL-1) return to their initial position by spring force.

The pause time begins. The system is ready to carry out a new lubrication cycle.

1.2.2 System 2 After the pause time has elapsed, the pump supplies the lubricant to the connected progressive metering devices.

A progressive metering device 8 (SSV) is equipped with a proximity switch for control and monitoring.

A lubrication cycle is completed after the SSV has supplied twice, and the pump is switched off again.

Operation

CAUTION Only allow operation by properly instructed personnel Do not exceed permissible system pressures Top up lubricant or change drum in good time When the machine is started all centralized lubrication systems are automatically pressurized.

Each pump triggers one lubrication cycle, stops only for the preadjusted pause time, ... etc.

When the excavator is delivered from the factory the time period between two lubrication cycles is 6 minutes for pump P1 and 8 minutes for pump P2. This corresponds to a grease consumption of approx. 600 g/h for P1, 20 g/h for P2.

Manual

The lubrication system monitor CAUTION Only allow operation by properly instructed personnel Do not exceed permissible system pressures Top up lubricant or change drum in good time When the excavator is started the lubrication system is automatically alive.

The lubrication pump then carries out a complete lubrication cycle, is stopped only for the duration of the set pause time, etc....

The pause time is factory set at 2 hours.

During lubrication the diesel engine must be in operation because the lubrication pump is driven via the compressed air of the excavator.

During a lubrication cycle, the pump function is represented by a rotating girder on the field indicator.

The delivery of grease can be checked by ensuring that the control pin of each injector moves back and forth.

a

b

The flashing of the pushbutton C indicates a malfunction in the automatic lubrication system (lubrication cycle still not completed after about one hour).

The fault is also indicated by means of an intermittent whistling sound at the control unit. Possible causes of malfunction are: Blockage or breakage of the main line Fault at the pressure switch Lack of lubricant in the grease reservoir Fault in the power supply of the lubrication system Fault in the compressed air system

c

d

e

An additional lubrication cycle can be triggered at any time by pressing the key c on the control unit U15 (at least 2 sec).

On malfunction of the command unit U15, an additional lubrication cycle can be triggered by key S84-2 of the emergency unit command E52.

Operating Manual

3 Safety recommendations to be complied with General behaviour when handling the system The centralized lubrication system, pump or single components may be used only in awareness of the potential dangers, in proper technical condition, and according to the information in these installation instructions.

Familiarize yourself with the functions and operation of the product. The specified assembly and operating steps and their sequences must be observed.

Any unclear points regarding proper condition or correct assembly/ operation must be clarified. Operation is prohibited until issues have been clarified.

Keep unauthorized persons away from the centralized lubrication system.

Precautionary operational measures and instructions for the respective work must be observed.

Responsibilities for different activities must be clearly defined and observed. Uncertainty seriously endangers safety.

Safety-related protective and emergency devices must not be removed, modified or affected otherwise in their function and are to be checked at regular intervals for completeness and function.

Remedy occurring faults in the frame of responsibilities. Immediately inform your superior in the case of faults beyond your competence.

Do not reach into the system during operation.

Wear personal protective equipment always.

When handling lubricants observe the relevant safety data sheets and operating instructions by the lubricant manufacturer or supplier.

Never use parts of the centralized lubrication system or of the machine as standing or climbing aids.

Explosion protection Always behave so that fire and explosion hazards are avoided.

A written work approval from the operator is required prior to working in potentially explosive areas.

There must be no indications that parts of the explosion protection are missing or are not working. Should such indications become apparent, switch off the machine and inform a superior without delay. Keep unauthorized persons away.

Measures for explosion protection must never be deactivated, modified or bypassed.

It is forbidden to bring in ignition sources such as sparks, open flames and hot surfaces in potentially explosive areas.

The ignition temperature of the lubricant must lie at least 50 K over the maximum admissible surface temperature of the components.

Only use tools and clothing which are permitted for use in potentially explosive areas (ESD).

Transport, installation, repairs and work on electrical components may only be carried out, if it has been ensured that the atmosphere is not potentially explosive.

LEC / en / Edition: 03 / 2018

Check the machine at regular intervals for damage which may represent an ignition risk.

Operating Manual Repairs or modifications to machines which are protected against explosions may be carried out only by the manufacturer or by a workshop recognized by a named institution and confirmed in writing.

If the work is not carried out by the manufacturer, the repairs must be approved by a named expert and confirmed in writing. The repairs are to be marked by a repair sign on the machine, stating the following: o Date o Executing company o Type of repair o If applicable, expert's code Transport damages can result in the loss of the explosion protection. If transport damages can be seen, do not assemble the machine or put it into operation All parts of the earthing concept must be correctly available and connected with the superordinate machine.

If transport lugs are dismantled after set-up, the threaded bores must be permanently sealed in accordance with the protection class.

Handle the materials so that no sparks are generated by tilting, falling, sliding, rubbing, impacting, etc. If needed, cover materials with suitable means.

Never disconnect plug-in connections when energized. Secure plug-in connections against inadvertent manual disconnection with the safety clips included in the delivery.

The operator must check critically whether operation without a low-level signal might lead to a new risk potential (e.g. through heat-up of bearing points on the machine in the area of ignition temperature, poor lubrication or bearing damage). If this cannot be ascertained, provide a low-level signal or suitable organisational measures for monitoring of the bearing point temperature.

Avoid dust accumulation and remove dust immediately. Dust accumulations have a thermally insulating effect and, if whirled up, generate the formation of a potentially explosive atmosphere.

The pump should be integrated into the operator's lightning protection concept.

All parts are to be checked regularly for corrosion. Replace the affected parts.

Terminal boxes must be firmly closed and the cable breakthroughs correctly sealed.

Additional electrical monitoring devices must be firmly connected and correctly adjusted.

LEC / en / Edition: 03 / 2018

Protect the motor with a motor circuit breaker against inadmissible heating up. When reaching their nominal life, the motor bearings have to be replaced or inspected to ensure their suitability for further utilisation.

Transport / installation / maintenance / repairs / servicing All relevant persons (e.g., operating personnel, supervisors) must be informed of the respective activity prior to starting any work. Observe the precautionary operational measures and work instructions.

If protective and safety equipment has to be dismantled, it must be reassembled immediately after finishing the work, and then checked for correct function.

Ensure through suitable measures that movable or detached parts are immobilized during the work and that no limbs can be caught in between by inadvertent movements.

Carry out transport using only suitable hoisting equipment.

Operating Manual If transported separately (e. g. repair) lift the motor by means of the transport lugs or eye bolts. Ensure that transport lugs or eye bolts are firmly seated. Do not carry any further load on the transport lugs or eye bolts. Do not transport motors on the fan cover.

Assemble the pumps and other components only outside of the operating range of moving parts, at an adequate distance from sources of heat or cold.

Dry wet, slippery surfaces.

Cover hot or cold surfaces accordingly.

Prior to performing work, de-energize and depressurize the pump and secure it against unauthorized switch-on. Work on electrical components must be carried out by electrical specialists only. Observe any waiting periods for discharging, if necessary.

Carry out electrical connections only according to the information in the valid wiring diagram and taking into account the relevant regulations, the local connection conditions and legal prescriptions (e.g. DIN, VDE). Electrical connections must be done in such way that no forces are transferred to the product (tension-free connection).

Do not touch cables or electrical components with wet or damp hands.

Maintenance and repair work can be subject to restrictions at low or high temperatures (e.g. changed flow properties of the lubricant). Therefore, where possible, try to carry out maintenance and repair work at room temperature.

Carry out all works on electrical components using adequate, voltage insulated and technically proper tools only.

Fuses must never be bridged but have to be replaced by the same type of fuse always.

Determine the cause of the failure of the fuse.

Ensure correct earthing of the electrical system.

Undertake drilling at non-critical, non-load bearing parts only. Use any available boreholes. Do not damage lines and cables when drilling. It is essential to observe the machine manufacturer's installation instructions and to consult the machine designer in case of doubts.

Operating Manual Observe the specified tightening torques. When tightening, use a calibrated torque wrench.

When working with heavy parts use suitable lifting tools. If need be, consult the responsible safety officer.

Avoid mixing up or wrong assembly of dismantled parts. Mark these parts accordingly.

Laying of the lubrication lines When laying the lubrication lines, observe the following information in order to warrant troublefree function of the entire centralized lubrication system.

CAUTION Environmental pollution Lubrication lines must be absolutely leakproof. Lubricants may pollute ground and waters. Lubricants have to be handled and disposed of properly. Observe all applicable prescriptions and laws regarding disposal of lubricants as well as the relevant safety data sheets.

Slipping hazard Centralized lubrication systems must be absolutely leakproof. Leaking lubricant is hazardous due to the risk of slipping and injury. During assembly, operation, maintenance and repair of centralized lubrication systems watch out for leaking lubricant. Leaks must be sealed immediately.

Dimension the lubrication line according to the maximum pressure and the output volume of the pump unit used.

Starting from the pump unit the main lubrication line should be laid preferably rising with a possibility to vent it at the highest point of the lubrication line system.

Mount the lubricant metering devices at the end of the main lubrication line in such way that the outlets of the lubricant metering devices show upwards. If lubricant metering devices have to be mounted below the main lubrication line, then this should not be done at the end of the main lubrication line.

The tube lines, hoses, shut-off and way valves, fittings, etc. have to be laid out according to the maximum operating pressure of the pump unit, the admissible temperatures and the lubricants to be supplied. Furthermore, the lubrication line system must be protected against inadmissibly high pressure.

Before the assembly thoroughly clean all components of the lubrication line system like tube lines, hoses, shut-off and way valves, fittings, etc. In the lubrication line system no seals should protrude towards the inside, as the lubricant flow could be impeded and contaminations could enter the lubrication line system.

LEC / en / Edition: 03 / 2018

Lubrication lines shall generally be laid in such way that there can never be created air pockets at any point. Avoid changing the cross sections of the lubrication line from smaller to larger cross sections in the lubricant flow direction. Design cross section transitions as smooth as possible.

The lubricant flow in the lubrication lines should not be impeded by the installation of sharp elbows, angle valves and check valves. Provide unavoidable changes of the cross sections in the lubrication lines with as smooth transitions as possible. Avoid sudden changes of direction, if possible.

Operating Manual 9.2.2 Greasing cycle When the pause time has lapsed, the pump starts operating and supplies the lubricant via the main line to the LM5 injectors. The pistons inside the injectors are operated via lubricant pressure. A premetered amount of lubricant is dispensed to the connected SSV. After all injectors have operated, the pressure in the main line rises until the preset pressure on the pump is reached 240 bar. The control unit stops the pump via the pressure switch B69. The pump stops running and the relief valve is deactivated at the same time. The compressed lubricant in the main line can flow back into the reservoir, the pressure drops. When the pressure has fallen below 80 bar the pistons inside the LM5 injectors return to their initial positions by means of spring force and reload the adjustable amount of lubricant by this action.

The pause time can start and the system is now ready for another lubrication cycle.

Operating Manual 9.2.3 Single-line system The single-line system consists of a pump to supply lubricant under pressure to the injector metering devices via the supply line. The injector metering devices deliver lubricant to a secondary (progressive) metering device or to the bearing through feed lines.

The lubrication cycle is initiated by an automated pump. The injectors have indicator stems, which move in and out to indicate that they have been cycled.

A controller will control the automated system.

LEC / en / Edition: 03 / 2018

The time between on cycles and the length of off cycles is adjustable. The controller includes the timer function above with a monitor function and alarm capability. A pressure switch is used to indicate when system pressure has been reached to turn off the pump and verify that a lube cycle has been completed. If the pressure switch does not detect full pressure within a preset period of time, the controller goes into alarm state.
