The important task of the power generator fuel pump is to ensure that diesel circulates in the low-pressure oil circuit and continuously provides sufficient quantity and pressure of fuel to the fuel injection pump. The use and maintenance methods of diesel generator fuel transfer pump mainly include the following aspects:
一、 The usage method of the power generator oil pump
1. Pre installation inspection: Before installing the fuel pump, it is necessary to first check whether the model and specifications are correct, and clean the rust proof oil. When selecting gaskets, ensure that their thickness is appropriate to avoid abnormal piston operation caused by being too thin or too thick.
2. Lubricating oil inspection: Before starting the generator, check whether the lubricating oil in the oil delivery pump is sufficient and ensure that the lubricating oil meets the regulations of the generator set manufacturer.
3. Pre run: After starting, let the power generator oil pump run for a period of time to ensure that the lubricating oil reaches the lubrication point before starting the generator set.
4. Regular inspection: During the operation of the power generator, regularly check whether the lubricating oil of the oil pump is sufficient, and add it in a timely manner if it is insufficient.
5. Handling of long-term disuse: If the oil pump is not used for a long time, it should be tested regularly to ensure its normal operation.
二、 The maintenance method of the power generator oil pump
1. Cleaning the filter screen: As the coarse filter core in the oil pump joint is prone to clogging due to dirt, it is necessary to regularly inspect and clean the filter screen. If it is damaged, it should be repaired or replaced in a timely manner.
2. Protect the rubber sealing device: Do not disassemble the rubber sealing device on the fuel pump at will. Once the rubber ring is found to be damaged, it should be replaced in a timely manner.
3. Check the "four springs": Ensure that the elasticity of the "four springs" (piston spring, plunger spring, inlet valve spring, outlet valve spring) of the plunger oil pump is normal. If they weaken or break, they should be replaced or adjusted in a timely manner.
4. Replace the sealing gasket: Regularly check the integrity of the sealing gasket, replace it in a timely manner if it is damaged, and ensure that the plastic gasket is not disassembled too many times.
5. Drain hole treatment: If the fuel pump has a drain hole, do not block it to prevent oil from entering the oil sump of the fuel injection pump and diluting the lubricating oil.
6. Rust prevention treatment: For generators that have been shut down for a long time, necessary rust prevention measures should be taken to prevent the surface of the oil pump from rusting due to excessive moisture.
7. Check the quality of diesel: Ensure that the injected diesel is filtered through sedimentation, kept clean, and avoid parts wear caused by excessive impurities.
Following the above usage and maintenance methods can ensure the stable operation of the power generator fuel pump and provide fuel assurance for the normal operation of the unit.
