Introduce to you the general knowledge of gear oil pump maintenance

As the usage time increases, gear pumps may experience problems such as insufficient or even no oil pumping, mainly due to excessive wear and tear on the relevant parts. The wear parts of gear pumps mainly include the active shaft and bushing, the passive gear center hole and shaft pin, the pump housing cavity and gear, the gear end face and pump cover, etc. When the main technical indicators of the lubricating oil pump fail to meet the requirements after wear, it should be disassembled, the worn part and degree should be identified, and corresponding measures should be taken for repair.
