 How to repair the wear and tear of the gear pump (gear pump) |
 1. diesel engine gear oil pump drive shaft and bushing wear after repair due to the oil pump drive gear weight and passive gears meshing of the radial thrust, easy to produce eccentric wear of the shaft and bushing holes, the gap increases. Therefore, oil will be at work because of the gap increases leakage, reduced fuel supply. ? Driving shaft and bushing wear, available repair journal or repair bushing method to recover with the gap.Journal wear is minor, just press out the old bushings replaced with a new bushing, while the axis generally do not repair, so with the gap to recover to the extent permitted. Very serious to the shaft and bushing wear, with the gap increased, not only to replace the bushing, and shaft applications chrome or vibration surfacing will increase the diameter and then grinding to a standard size in order to restore the journals and bushing with the requirements.
2, the repair of the pump housing cavity and tooth wear? Pump housing cavity and tooth wear, a great influence on the fuel pump. When the shaft and the bushing or shaft bore wear serious, work the surface of the tooth tip and the pump housing cavity will produce undue exposure. Also, because of the oil chamber into the oil chamber pressure, under the pressure difference, into the oil chamber near the more contact with the pump housing cavity here wear more, the gap increases, the cavity and the tooth top. The resulting oil pump into the pressure difference between the oil chamber to decrease, so that the tooth scraper and the role of oil pressure to reduce, causing the oil pressure drops, reduced fuel pump. The wear of the pump housing cavity in general, the cavity insert sets to be restored. Second, due to the wear of the tooth in the tooth thickness direction, the main driven gear meshing gap increases. The wear is characterized by unilateral wear heavier, so the gear can be rotated 180 degrees to use.
3, the gear end and pump cover wear and tear, repair of the gear face and pump cover between the plane left a certain gap, said end clearance. Gear face and pump cover work within the plane of the contact surface wear and tear will end gap increases when over the limit will have a significant impact on the fuel pump.
When the gear face wear, face polished, grinder pump housing to decompose the surface in order to ensure end clearance of the gear pump in the required range.
