Process characteristics and service life of gear oil pump

Gear oil pumps are suitable for transporting lubricating liquids with a temperature not exceeding 70 ℃. If a high temperature of 200 ℃ is required, high-temperature materials can be used with a viscosity of 5× 10-5~1.5× 10-3m2/s。 This pump is not suitable for transporting corrosive, hard particle or fiber containing, highly volatile or low flash point liquids such as gasoline, benzene, etc. Gear oil pump is a commonly used hydraulic pump in hydraulic systems, which is generally made as a quantitative pump. According to different structures, gear oil pumps are divided into external gear pumps and internal gear pumps, with external gear pumps being more widely used. It is an important component that lifts low-pressure oil in the oil tank to high-pressure oil capable of doing work through the mutual rolling meshing of a pair of involute gears with the same parameters and structure. It is a power device that converts the mechanical energy of an engine into hydraulic energy.
