The reason for internal leakage caused by wear of internal parts of gear oil pum

Gear oil pump is an important component that uses a pair of involute gears with the same parameters and structure to roll and mesh with each other, raising the low-pressure oil in the oil tank to high-pressure oil that can do work. A power device that converts the mechanical energy of an engine into hydraulic energy. The gear oil pump has a large flow rate and good performance. It is prone to wear and tear during use, and maintenance should be taken into account.
