General information as to dangerous situations

For all work performed on the turbo coupling, please observe the local regulations for prevention of accidents!

DANGER!

– Working on the turbo coupling: For all work carried out on the turbo coupling ensure that both, drive motor and driven machine have stopped running and startup is absolutely impossible!

Start your work only after the coupling has cooled down below 40°C, otherwise there is a risk of burns!

– Temperature rise in the turbo coupling: The coupling temperature rises during operation.

Please provide a guard for protection against contact with the coupling! However, ventilation of coupling must not be impaired.

Never use fluids to cool down the coupling!

– Rotating parts: Rotating parts, for example, the turbo coupling itself and exposed shaft parts need to be protected against contact by a guard!

However, ventilation of coupling must not be impaired.

Never operate the coupling without these guards!

– Sprayed-off operating fluid: In the event of thermal overload of the turbo coupling, the fusible plugs respond. Operating fluid is discharged through these fusible plugs.

Voith. Operating Manual

Turbo Couplings with Constant Fill

– Electrical components: Guard against electric shock!

Contact with open or free terminals, lines and components may cause serious or even fatal injuries!

In the event of a fault even operationally potential-free assemblies may have a respective potential.

Avoid body contact with earthed or grounded surfaces!

– Control of methane content prior to Works on the turbo coupling:

Installation and Operating Manual 3626-011300(ex) en.

Voith Turbo GmbH & Co. KG. 2004-08 / Rev. 6, Printed in Germany.

Subject to modification due to technical development.

In order to guarantee safety of works on turbo couplings with housing of aluminium alloy and the guard of which has been removed during underground installation, maintenance and dismounting, the methane content has to be controlled locally using appropriate devices. Prior to starting and during performance of these woks the methane content in the area of turbo coupling must not exceed the permissible limit (1 Vol.-%). Should this limit value be exceeded, all works have to be stopped until the local value falls under the limit value again.

4.3

Important information as to operation

ATTENTION!

– Power transmission: The cover sheet of this operating manual shows the possible power transmitted at a specific input speed and a specific coupling fill (operating fluid and fill). These values describe a permissible working point for steady operation of coupling.

Voith Turbo’s approval is required for steady operation of coupling at a different working point!

– Operating fluid: Use only the operating fluid mentioned in chapter 1 of this operating manual! Operate the turbo coupling only with the operating fluid fill shown on the cover sheet of this operating manual.

Some too low fill would cause thermal overload of coupling and, in case of an overfill, the internal pressure could damage the coupling.

– Temperature rise during startup: During startup, the temperature in the turbo coupling rises more than during steady operation due to higher slip. Observe that the intervals between starts are sufficient to avoid thermal overload!

– Starting characteristic of turbo couplings with delay chamber: During startup, the operating fluid is delivered from the delay chamber into the turbo coupling working chamber. On standstill, the operating fluid flows back into the delay chamber. Observe that the intervals (a few minutes!) between starts are sufficient to obtain a correct starting characteristic!

EX-PROTECTION! / ATTENTION! – Coupling temperature:

Turbo Couplings with Constant Fill; Operating Medium Water.

Voith Turbo GmbH & Co. KG. 2004-08 / Rev. 6, Printed in Germany.

Subject to modification due to technical development.

During steady operation, the coupling temperature must not exceed 85°C! Overheating may damage the coupling!

14

– Ambient temperature: Ambient temperature must be above freezing point of operating fluid! The frozen operating fluid may damage the coupling.

Voith. Operating Manual

Turbo Couplings with Constant Fill – Fusible plugs: The fusible plugs protect the turbo coupling against damage due to thermal overload.

Switch off the drive motor immediately on response of one of the fusible plugs!

Chapter 1, page 5

Use original fusible plugs only with the nominal response temperature shown on the cover sheet of this operating manual!

– Operating fluid sprayed off and leaking out: The fusible plugs respond in the event of thermal overload of turbo coupling. The operating fluid leaks out through these fusible plugs.

Electrical devices located near the coupling need to be protected against spraying!

Note!

Turbo couplings suitable for operating medium water are marked with blue paint at the outer diameter of flange.

EX-PROTECTION! – Overload of the coupling: On response of the thermal fuse switch off power supply after the time required in Chapter 1 at the latest.

If additional monitoring of overload is required, monitor output speed.

If the output speed falls below the input speed by more than 10%, immediately switch off power supply.

Chapter 1, page 5 Chapter 1, page 5

It is necessary to switch off the power supply, otherwise the max. surface temperature indicated there cannot be kept

Function, Types

5.1

Function

bladed wheels

shell

Fig. 1

The Voith turbo coupling is a hydrodynamic coupling working to the Föttinger principle. Its main components consist of two bladed wheels – the impeller and turbine wheel – enclosed by a shell. Both wheels are provided with bearings relative to each other. The power is transmitted virtually without wear, there is no mechanical contact between the powertransmitting parts. A constant amount of operating fluid is in the coupling.

The mechanical energy provided by the drive motor is converted to kinetic energy of the operating fluid in the connected impeller. In the turbine wheel this kinetic energy is converted back to mechanical energy.

Three conditions are to be considered as to the coupling function:

– Standstill: The total operating fluid is resting statically in the coupling.

Fig. 2

Voith. Operating Manual

17

Turbo Couplings with Constant Fill

– Starting condition: The impeller accelerates the operating fluid with increasing motor speed causing a circulating flow in the working chamber. The complete blade chamber of turbine wheel is flooded, starting to move as a result of the kinetic energy of fluid flow.

The coupling characteristic determines the torque curve during startup.

Fig. 3

– Nominal operation: During nominal operation only the torque required by the driven machine is transmitted. The low speed difference between impeller and turbine wheel (rated slip) results in a steady flow condition in the coupling.

Turbo Couplings with Constant Fill

11 Fill, Level Check and Draining – The quantity and type of operating fluid used determine the turbo coupling behavior substantially.

– Too high fill level leads to a higher load on the drive motor during startup and to higher stall torque.

– Too low fill level leads to higher thermal load of coupling and lower stall torque.

DANGER! Please observe, in particular, chapter 4 (Safety) when working on the turbo coupling!

CAUTION! – Operating fluids may cause irritations or inflammation when in contact with skin and mucous membranes.

– Please wear protective glasses for all work to be done in connection with the operating fluid!

– Should you get any operating fluid in your eyes, rinse them immediately using a lot of water and consult a physician!

– After you finished your work, clean your hands carefully with soap.

EX-PRROTECTION! / ATTENTION! – Impurities in the operating fluid cause an increased wear of the coupling and bearing damages. Then explosion protection is no longer given. Make sure that any containers, funnels, filling tubes etc., used for filling the coupling, are clean.

ATTENTION! – Observe the fill level and type of operating fluid mentioned on the cover sheet of this operating manual.

– Do not overfill! This would cause impermissibly high internal pressure in the coupling, which may destroy the coupling.

12 Commissioning EX-PROTECTION! – Equipe the coupling with a protective cover (e.g. perforated plate, size of holes approx. 10-12 mm). This protective cover needs to be designed to: prevent intrusion of damaging foreign matter (stones, corrosive steels etc.). withstand the impacts to be expected without excessive damages, thus preventing contact of the coupling with the guard. Especially couplings with aluminium surfaces are not to contact corrosive steel or iron parts. catch spraying solder of fusible plugs. catch leaking operating fluid in order to prevent damage on electrical devices and ignition sparks. provide sufficient ventilation to maintain the maximum surface temperature specified. guarantee safe distance against hazardous points or situations (DIN EN 294 and DIN EN 811).

The turbo coupling is not equipped with insulated ball and roller bearings! Current passage and stray currents are possible from the machines connected (e.g. VFD).

To avoid static charging or load prevent turbo coupling installation with an insulation on both sides.

Provide equipotential bonding between input and output.

– Provide units with possible overspeed with a device preventing overspeed safely (for example: brake or back stop).

DANGER! Please observe, in particular chapter 4 (Safety) when working on the turbo coupling!

ATTENTION!

Voith. Operating Manual

Turbo Couplings with Constant Fill Note!

– At the periphery the couplings are provided with an identifying mark according to Directive 94/9/EG and EN13463. The identifying mark specifies the potentially explosive atmosphere and the operating conditions permitted.

Example:

II 2D c 135˚C X

– The turbo coupling may be used for any direction of rotation.

– The direction of rotation of driven machine may be specified! The direction of rotation of motor must be in accordance with the specified direction of rotation of driven machine!

– If the motor is started with star/delta connection, switchover from star to delta connection should be effected after maximum 2...5sec.

– In the event of a multi-motor drive you should determine the load of individual motors. Great differences in motor load may be balanced by an appropriate adjustment of the respective coupling fill levels.

However, do not exceed maximum permissible coupling fill level!

EX PROTECTION! Check whether, according to its marking, the coupling is approved for operation in potentially explosive atmospheres.

Check, whether the flexible connecting coupling (EVK) touches.

If you use a BTS-Ex to limit the maximum surface temperature, make sure not to exceed the maximum permissible temperature of the turbo coupling when switching on the motor.

Check reference dimensions of commissioning (see chapter 13.2.1).

18 Temperature Monitoring EX PROTECTION! The thermal switching elements MTS and BTS may be used in potentially explosive areas to monitor the temperature. The signals indicate pre-alarm. MTS and BTS do not limit the maximum surface temperature.

BTS-Ex is available as safety element for limitation of the maximum surface temperature and can be used as thermal switch-off device.

In this case, too, never replace the existing fusible plugs by fusible plugs with different nominal response temperatures or by blind screws.

18.1 MTS mechanical thermal switch unit for pre-warning Function: On excess temperature, the switching element releases a pin.

During rotation, the pin activates a switch. This signal, for example, may trip an alarm or switch off the drive motor. The switching element needs to be replaced.
