Sauer Danfoss (Turolla) Gear Pumps

Overview Of Jacking Oil System

Sauer Danfoss gear pumps provided by P&R Hydraulics Ltd 01603 424880 - P&R Hydraulics Ltd is an official Sauer Danfoss distributor and may provide a spread of hydraulic components. The lube oil supply downstream of the lube oil filter feeds the turning gear pump, which is pushed by the same AC-Motor that drives the jacking oil pump. Oil that's discharged from the pump is guided to the common turning gear housing, which consists of an axial movable drive pinion, a coupled radial piston motor and a control block. Piston strikes axially in opposition to a spring drive within the route of the gear rim on the turbine shaft.

Gear pumps are simple, sturdy and cheap pumps that are suitable for pressures below 20 MPa (3,000 psi). These pumps fall underneath positive displacement, which means that they pump a steady amount of fluid for each cycle. The liquid is then trapped by the gear teeth and compelled out to the outlet throughout the discharge stroke. For lubrication, the gear pump utilises a small quantity of oil that comes from the forced side of the gears that flows through the hydrodynamic bearings and expels the same oil to the a part of the gears with low pressure.

Interact the drive pinion, a solenoid valve is activated, which exerts lube oil stress on the piston of the drive pinion. On the same time, creep speed operation of the radial piston motor is started by the pressure from the strain lowered oil from the turning gear pump to guarantee engagement of the drive pinion. Then the engagement solenoid valve is switched off, the turning gear stays engaged by the constructive torque of hydraulic motor.

After engagement, controlled by a limit change, the complete strain from the turning gear pump is provided to the radial piston motor turning the shaft with full turning gear pace. Two solenoid valves, one for creep velocity Vane pumps and the other for full velocity, management the turning gear oil provide. The turning gear pump and the jacking oil pump are pushed by one widespread AC motor.

So, if you are searching for environment friendly submersible pumps , water pumps and other pumps in Australia, then it is best to rent dependable pump providers. Pump Solutions Australasia are importers and distributors of quality European pumps and filters. Jacking oil system protects the turbines journal bearings throughout begin-up and shut-down. Turning gear system rotates the turbine shaft so that it will not bend, resulting from uneven temperature distribution. Turning gear pump is an axial piston sort, which is located on the lube oil tank.
