Technical Problems in Application of Triple Gear Oil Pump
Release time:
2019-06-08
Disassembly and disassembly of the triple gear oil pump should be carried out in a clean place. After the removed parts are cleaned with gasoline or diesel, carefully check the grinding state of each part to confirm whether it can continue to be used, and then use the parts that can continue to be used. Place carefully in order.
Technical requirements for assembly of triple gear oil pump:
1. When assembling, the joint surface and friction surface of each accessory should be coated with engine oil, and the self-tightening oil should be sealed into the oil pump cover, and the sealing table should not be damaged.
2. Clean the whole accessories with gasoline or diesel, and carefully check the technical status of each accessory. During assembly, the width of the driving gear and the driven gear are required to be the same to ensure that the gear end face and the shaft sleeve end face fit tightly during the operation of the oil pump; when the sleeve gear set is installed into the housing, an axial clearance of 0.10-0.12mm should be guaranteed; The small sealing ring should be higher than the ring, and should have a pre-compression of 0.40-0.55mm, and the pre-compression of the large sealing ring is 0.6-0.7mm.
3. The pressure relief of the shaft sleeve is beneficial to remove the closed dead volume generated during gear meshing, so pay attention to the pressure relief position during assembly. The pressure relief plate and the sealing ring shall be located on the side of the oil suction chamber, that is, on the side of the large hole with the word "inlet" in the oil pump housing.
4. When screwing the screw on the pump cover to the shell, it should be rotated several times alternately, and the torque is 49 ~ 59N · m.
5. When the assembled triple gear oil pump rotates the driving gear by hand, it should be smooth and free of straps, and the rotation torque should not be greater than 3N · m.
When 2. disassembling the gear pump, the following questions should be paid attention:
1, the gear pump is a precision component, in the absence of a fault is not judged to occur in the gear pump, generally do not easily disassemble.
2. After disassembling the gear pump assembly, the oil and dust outside the oil pump assembly should be cleaned first. Before disassembling, make a mark on the pump cover and the pump body with a steel sheet (try to use a marker pen) so as to assemble according to the mark.
3. Parts that are severely worn and cannot be used continuously should be replaced with new parts in complete sets or in pairs. If a pair of gears should be replaced, otherwise the difference between the two gears will affect the pressure of the oil delivery.
4. Disassembly and disassembly of the triple gear oil pump should be carried out in a clean place. After the removed parts are cleaned with gasoline or diesel, carefully check the grinding status of each part to confirm whether it can continue to be used, and then continue to use The parts, carefully put them in order.
