What are the reasons affecting the service life of hydraulic pump?

According to many years' experience of the construction machinery's home, for the analysis of several factors affecting the service life of hydraulic pump are as follows: 1, bearing wear of bearing wear is affecting the service life of hydraulic pump soft decision factors. Hydraulic pump with bearing is in the specific operation conditions and specific load special bearing friction torque. This kind of bearing in the job happens 'partial edge effect', this will inevitably decline bearing rated using become old, yea, could also affect hydraulic pump soft measure to bring together. 2 plunger pump oil, the oil pollution of the oil pollution is mainly formed by human pollution. When replacing hydraulic filter without the cartridge or oil free base will not discharge the oil in the cartridge is ChouHuan filter, the formation of pollutants from the cartridge within the cartridge PaiKou directly into the fuel tank. When there are particles into the hydraulic pump will be formed on the surface of the valve in a scratch, when scratch under the high pressure oil long-term washout will turn into a groove, will form the hydraulic pump failure.
