Overview Of Jacking Oil System

Overview Of Jacking Oil System


It is extremely easy and easy to change the gear oil or gear lube in the lower unit or gearbox of your outboard motor. Have interaction the drive pinion, a solenoid valve is activated, which exerts lube oil stress on the piston of the drive pinion. At the same time, creep velocity operation of the radial piston motor is started by the drive from the strain reduced 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 positive torque of hydraulic motor.


The jacking oil system and the turning gear system belong to the same function group controller. Turning gear operation without jacking oil switched on will not be allowed, because the bearings may be damaged as a consequence of insufficient lubrication. Case of an emergency the turning gear system could also be switched-off for a most of quarter-hour after someday and 30 minutes after 2 days steam turbine shut-down. Examples shown are group 3 gear pump sequence SNP3/SNP3NN (on the left) and group 2 gear pump sequence SNP2/SNP2NN (on the right). The pressure balanced design of the pumps provides high effectivity for your complete sequence.


Gear pumps are easy, durable and cheap pumps that are appropriate for pressures below 20 MPa (three,000 psi). These pumps fall beneath positive displacement, which implies that they pump a gradual quantity of fluid for each cycle. The liquid is then trapped by the gear enamel and forced out to the outlet during the discharge stroke. For lubrication, the gear pump utilises a small amount of oil that comes from the compelled aspect of the gears that flows by means of the hydrodynamic bearings and expels the identical oil to the a part of the gears with low strain.


Interact the drive pinion, a solenoid valve is activated, which exerts lube oil strain on the piston of the drive pinion. At the similar time, creep velocity operation of the radial piston motor is began by the pressure from the stress Tu 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 positive torque of hydraulic motor.


The lube oil provide downstream of the lube oil filter feeds the turning gear pump, which is pushed by the identical AC-Motor that drives the jacking oil pump. Oil that is discharged from the pump is guided to the frequent turning gear housing, which consists of an axial movable drive pinion, a coupled radial piston motor and a control block. Piston moves axially against a spring force within the direction of the gear rim on the turbine shaft.
