Treatment of three failures of diesel generator fuel injection pump

1,Diesel generatorsFuel pump shaft breakthrough
If the injection pump four non-fine bolts are tight in the engine, the pump pump and the pump dry mill, there will eventually lead to the occurrence of changes in the mounting of the fuel pump, fuel pump, drive shaft from different new stone Room break.
The solution is to make a pump and pump pad between the appropriate thickness of the copper skin. To eliminate the gap. The re-injection pump is installed, first cleans the threaded hole, then four fixed bolts tighten the torque requirements, and check the degree of the oil pump shaft and the drive shaft, which does not meet the standard, should be re-adjusted. The proposed demolition fuel pump can be deleted with the seat together.
2. Enter the oil diesel injection fuel pump wear.
This failure, oil has increased significantly, and with related diesel flavors, plus oil prices from a serious mouth or exhaust. For the piston pump, diesel entering the oil, only these two channels; diesel directly enters the boss of the oil pump side roller pump directly in the next-door room; the fuel pump plunger wear is superb, resulting in the intra-cylinder inner leakage, diesel internal leakage Will flow into the lubricant.
The solution is to open the roll-on pump side cover, start the diesel engine, if the cylinder diesel leak, indicate that the cylinder piston is overdue, and the plunger is replaced, and should be sprayed at the calibration pump test table. Remove the pump pump pump oil, if the fuel pump wheel is in the immigration of diesel smoke, it demonstrates that the fuel pump has failed. It is also possible to delete the fuel pump and connect tube, tighten the hand pump, block the fuel pump, which is introduced into natural gas from 0.4 MPa. If the gas wheel side gap is discharged, it demonstrates that the input oil pump is faulty and should be replaced. .
3, high pressure fuel pump out of oil port and pipe joints in oil leakage
The cause of the fault, the oil-pumped high pressure of the fuel pumps, due to wear, caused oil leaks Mifengbuyan street. The solution is that it can be in the injection pump out of the recess concave circular copper pad oil port connector. This pad has a school pump that can be leakage with the school pump, injector and high pressure tubing point may also be proved to prove that it is very good in practice.
Remarks: The test procedure of the diesel generator set, and the units in the diesel generator controller are operated and tracking data from data from air pressure, hydraulic pressure. Therefore, the stability of diesel generator controller quality, design is highly required. Our starlight has more than ten years of production experience. The quality and service of our products can meet the requirements of the majority of users, and get a good comment from the market!
