The use of a certain period of time, the parts of the hydraulic pump will gradually wear even damaged, it will reduce the pump running precision and performance, oil pressure not hit up, reduce the amount of oil, increased noise, vibration increases and so on each kind of abnormal phenomenon will the resulting.Hydraulic pump in daily use, the installation of the pump, oil, operation of the exclusion of failure if you can master, hydraulic pump parts wear or avoid damage can be greatly eased.Reasons for damage of hydraulic pump(1) wear and tearThe wear of hydraulic pump parts, like any part of the equipment, is the inevitable result of the mechanical operation. Under normal conditions of use, due to friction and chemical reaction and other factors, the long-term effect of wear and tear, which belongs to the natural wear and tear. This wear is not eliminated and avoided, but through careful maintenance and proper use of the pump, wear can be delayed, prolonged wear cycle.The causes and p
