cavitation effect of the hydraulic system

Cavitation in the hydraulic system is usually disastrous consequences. An axial piston pump plunger hole in the metal erosion will occur. Pump inlet pressure but not high enough to its suction stroke of the plunger is retracted so that the liquid accelerated into the plunger hole. Liquid to form a hole, when these holes next to the plunger hole wall collapse,  Hydraulic tube fittings  pressure (transient may reach 4.5 × 104Mpa) knocked off from the wall or chipping off a little metalDamage to the gear pump can be displayed side by side, that is envisaged in the low pressure suction side of the holes are produced by both the high pressure side to the oil discharge side and is crushed to be explained (such damage may also be caused by air inclusion, as cavitation caused by the same).In the vane pump, the occurrence of cavitation clear signs of the blades of the stator on which the sliding surface ripples. Since cavitation, leaf becomes unstable, tend to bounce back and forth instead of sliding.
