The role of the oil delivery pump is to ensure that the diesel oil circulates in the low pressure oil circuit, and to ensure that a certain amount and pressure of diesel oil is transmitted to the injection pump through the diesel hose and the diesel filter. In order to prevent the failure of the oil pump of the diesel generator set in the work, then how should we repair it normally? The following Beidou power for you to answer this question.
The maintenance of oil pump is mainly the following aspects
1. Repair of pump body
All the oil channels of the pump body should be unimpeded, and the interface thread should not be damaged; The bottom plane of the check seat should not be damaged; The inner cavity of the piston in the pump body should not be damaged. If the wear gap between the piston cavity and the piston is too large, it should be repaired or replaced with a new oil pump.
2. Repair of piston
The piston should have no cracks, serious scratches and excessive wear, etc. If there are slight scratches, it is generally available to research and repair the paste with the pump body.
3. Maintenance of the putter and the putter sleeve
The clearance between the push rod and the push rod sleeve is generally 0.003-0.006mm, and when it exceeds this range, it should use the method to eliminate the cone and oval of the inner wall of the push rod sleeve. It can also be used to increase the diameter of the push rod by chromium plating method, and then to cut it, and then carry out mutual research with the push rod sleeve.
4. Maintenance of hand oil pump
Remove the pump, plug the connector hole with the palm, and then press the pump button to check the tightness of the piston and pump body. If the palm feels a large suction, it indicates that the hand oil pump can continue to be used; Otherwise, it should be repaired or replaced; If the clearance between the piston and the hand pump body exceeds the limit value, the plunger sleeve can also be hinged and manually ground, and then fitted with a larger plunger, and replaced with a sealing rubber ring of the same specification to repair the hand pump.
5. Check valve repair
The working face of the check valve should be worn evenly, and deformation and rupture are not allowed; If there is slight deformation or step shape, it can be smoothed on the platform. If the check valve deformation is serious or ruptured, it should be replaced with a new part, and it can be used only after researching the working surface.
