Residual oil pump ZYB55 repair and maintenance

Residual pump ZYB55 With the growth of the use of time, there will be inadequate pump oil, pump or even failure, mainly due to excessive wear and tear on the parts. Residual oil pump ZYB55 wear parts are the main shaft and bushings, passive gear center hole and shaft pin, pump housing cavity and gear, gear end face and pump cover. Lubricating oil pump wear and tear of its main technical indicators fail to meet the requirements, it should disassemble, find out the location and extent of wear and tear, to take appropriate measures to be repaired. Residual oil pump ZYB55 shell cavity repair: cavity pump cavity wear, the general cavity set method to repair, about to enlarging the cavity after the set with cast iron or steel bushings. After setting the sleeve, the cavity enamel to the required size, and wear out the end face of the bushing to make it flush with the combination of the pump housing. Residual oil pump ZYB55 drive shaft and bush wear, KCB-300 with the gap increases, will certainly affect the pump oil. In this case, you can repair the drive shaft or bushing method to restore its normal with the gap. If the drive shaft wear slightly, simply press the old bushing and put on the standard size bushing, with the gap can be restored to the allowable range. If the drive shaft and bushing wear serious and serious with excessive clearance, not only to replace the bushing, and the drive shaft also applies chrome or vibration welding method to increase its diameter, and then grinding to the standard size, recovery and bushing With the requirements. Repair of the oil pump housing Repair of the crack in the housing: Crack of the housing can be cast 508 nickel-copper welding electrode. Welds to be close and yuan stomatal, with the flatness of the pump cover with no more than 0.05 mm flatness. Repair of drive shaft bushing hole: The repair of drive shaft bushing hole on pump cover is the same as repair method of wear of drive shaft bushing hole of housing. Residual oil pump ZYB55 working plane repair: If the working surface of pump cover less wear, manual grinding method can be used to eliminate wear marks, that is, put a little valve sand on the platform or thick glass, and then put the pump cover on the ground, the residue pump ZYB55 with the growth of the use of time, there will be inadequate pump oil, pump or even failure, ZYB gear pump is mainly due to excessive wear and tear parts. Residual oil pump ZYB55 wear parts are the main shaft and bushings, passive gear center hole and shaft pin, pump housing cavity and gear, gear end face and pump cover. Lubricating oil pump wear and tear of its main technical indicators fail to meet the requirements, it should disassemble, find out the location and extent of wear and tear, to take appropriate measures to be repaired. Residual oil pump ZYB55 working plane repair: If the working surface of the pump cover less wear, hand grinding method can be used to eliminate wear marks, that is, put a little valve sand on the platform or thick glass, and then put the pump cover on the grinding until wear Elimination of traces of work surface smooth so far. When the pump cover working plane wear depth of more than 0.3 mm, should be taken after the first turning grinding method to repair. Follower shaft wear and tear to wear and tear to eliminate traces of reaming method, and then press the hole reaming the actual size of the preparation of the driven shaft.
