Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to an automatic cleaning device for a pump chamber of an oil pump. Background technique [0002] At present, in the field of automotive oil pumps, after the oil pump is assembled, it is necessary to perform a performance test on the oil pump. After the performance test, there is residual oil in the pump cavity, which does not meet the product cleanliness requirements. In the early stage, kerosene cleaning is performed manually. This method has the following three methods: disadvantages: [0003] (1) Manual cleaning varies from person to person and cannot be guaranteed to be 100% clean; [0004] (2) Employees come into contact with a large amount of kerosene when cleaning, causing damage to human skin; [0005] (3) If it needs to be cleaned, the pump cover at the pump cavity needs to be disassembled. There is a secondary assembly, which takes man-hours, and the sec...
