Hydraulic Clutch
Global Marine Engineering Hydraulic Power Take Off
The GME series of hydraulic PTO’s features an extremely powerful, robust package capable of handling a very wide range of engine driven and general industrial applications.
The PTO’s incorporate a Hydraulically actuated clutch of a multi-plate type, with sintered outer plates and steel 'SINUS' inner plates. Pressure is applied to the plates via a piston which incorporates piston rings instead of seals, to accommodate high heat loading. Plate wear is automatically compensated for increased movement of the piston.
The sintered facing allows for high thermal capacity, surface speed, and wear together with a coefficient of friction that increases uniformly to give a smooth start. Cooling oil is also passed between the plates to increase the thermal capacity of the clutch and reduce heat generated during idling conditions. Since the clutch plates are continuously running in oil, plate contamination is avoided.
Clutch Control
The selection of engage and disengage of the clutch is made by the operation of a control valve. The standard operation is by a manual operated valve which can also be operated by a remote control cable. As a alternative to the manual valve, DC solenoids and pneumatic valve can be supplied.
Pneumatic control may be highly preferred in hazardous areas, DC solenoids can be remote controlled by a simple ON-OFF switch either from one or more stations.
Safety interlocking - by a series of relays and interconnections with a gear teeth pick-up is possible to ensure that a clutch cannot be engaged below or above given safe speeds. Also, it can be sequenced such that engagement or disengagement cannot occur until a prerequisite condition exists.
Shut Down - It is usually desirable for a clutch to be disengaged prior to stopping an engine. The solenoid either the pneumatic control valve can be arranged to automatically disengage when the engine is shut-off or when the engine speed is below a certain pre-determined figure.
