What are the fuel pump inspection items for diesel generator sets?
The main inspection items are as follows:1, the outer rotor and pump casing pump clearance;2, the internal and external rotor meshing clearance;3, rotor and pump cover face clearance;4. Flatness of pump cover.[diesel generator unit oil pump inspection notice]1, check valve planes such as abrasion, sag, pitting phenomenon, application of grinding paste on the plate grinding, severe cases should be renewed.2. The surface of the one-way valve seat on the shell should be replaced when worn or not smooth.3, the top rod and the top sleeve wear seriously, so that the gap increases, the seal becomes worse, diesel leakage seriously, you need to replace with the shell, or choose the enlarged size of the top rod, but need to pass mutual research.4, the coarse strainer tubing joints within the core, and easy to be cottony sundries plug, effect of fuel supply, it should always pay attention to the clean fuel and remove the dirt on the filter core.5, the hand pump piston rubber ring damaged, should be replaced in good time. After the center of gravity of the oil pump is assembled, the moving parts of the piston, the ejector rod and the other parts of the oil pump are required to be in good motion during the whole journey, and no blocking and blocking are allowed. The hand pump should be light and flexible. Pay attention to the installation of the one-way valve spring. The check valve spring must be accurately embedded in the spring slot.
