Description

Technical Field

[0002] The function of the manual fuel pump is to pressurize fuel into the fuel supply system before the diesel engine is started, so as to discharge the air in the fuel pipeline, fuel filter and injection pump, thereby ensuring that the diesel engine can start reliably and work stably.

[0003] Among the existing technical solutions, a new type of hand pump with publication number: CN205533038U is proposed, which includes a screw head, a push rod, a guide sleeve, an upper cover, a screw cover, a piston, an upper shell, a lower shell, a bottom plate, a drain valve, a filter element, a one-way valve assembly, a valve head assembly, a small shaft, a handle, an open nut, a manual valve, an oil inlet, and an oil outlet. The push rod is equipped with a screw head, a guide sleeve is sleeved around the push rod, and a screw cover is installed at the lower end of the guide sleeve.

[0004] In order to solve the problem that high-pressure oil enters the oil channel system, causing the valve plate of the one-way valve to be stuck, resulting in failure of the one-way valve and reduced sealing performance, the existing technology is to use a stainless steel mesh on the outside of the filter element to filter out particulate impurities in the fuel first, and then filter out part of the water again when passing through the inner lining nylon mesh and Teflon mesh, thereby performing a secondary water separation treatment on the fuel, so that the oil can be processed in a higher purity. However, the traditional hand pump may be used for a long time and the sealing is poor and low, which may easily lead to oil leakage in the hand pump. Utility Model Content
