Because a much moves relatively inside hydraulic pump,be to take the sealed kind with sealed clearance, when hydraulic pump works, the high-pressured oil that presses oil pocket flows to oil absorption antrum and other and low-pressure place through this clearance necessarily, formed leak thereby. Below small make up what will to everybody explain leak of hydraulic pump happening to answer measure to reach answer measure:
Main reason:
Bedspring damages among pump of ① force plunger, make cylinder body and distribute oil dish break sealing;
② oil seal or sealing ring are injured;
③ sealing contact surface is undesirable;
Wear away between the spare parts inside ④ pump, gap is too big.
Answer measure:
① changes bedspring;
② changes oil seal or sealing ring;
③ examination is repaired;
④ changes or deserve to grind afresh spare parts.
Above is leak of hydraulic pump happening should reach to measure answer measure, the condition of hydraulic pump leak is existence clearance and pressure difference, accordingly, control leak, reduce leak, make sure hydraulic pump works normally.
