The hydraulic oil pump consists of a pump body, a rectangular oil tank, a pressure handle and an ultrahigh-pressure steel wire braided hose. The power component of the hydraulic system is to convert the mechanical energy of the prime mover into the pressure energy of liquid, which refers to the oil pump in the hydraulic system, which provides power for the whole hydraulic system. The structural forms of hydraulic pump generally include gear pump, vane pump and plunger pump. There are three types of hydraulic oil pump connectors: straight-through, self-sealing and quick-connection.

Hydraulic oil pump is the power source of hydraulic system. The hydraulic oil pump we choose should meet the demand of the hydraulic system for pressure and flow, and at the same time, we should fully consider the reliability, service life and maintainability, so that the selected hydraulic oil pump can run in the hydraulic system for a long time. There are many kinds of hydraulic oil pumps, and their characteristics are quite different.
