The oil pump motor unit is composed of four parts: the pump body, the rectangular oil tank, the pressure handle, and the ultra-high pressure steel wire braided hose. The power element of the hydraulic system is to convert the mechanical energy of the prime mover into the pressure energy of the liquid. The oil pump, which powers the entire hydraulic system. The structure of the hydraulic pump of the oil pump motor unit generally includes a gear pump, a vane pump and a plunger pump. The hydraulic oil pump joint of the oil pump motor unit has three types: straight-through type, self-sealing type and quick joint.
Structural characteristics of oil pump motor unit:
Gear pump is mainly composed of pump body, gear, front cover, rear cover, bearing, skeleton oil seal and other parts.
The pump body, front and rear covers are made of HT250 gray cast iron, the gears are made of high-quality powder metallurgy, the pump shaft is made of 40Cr combined with steel hardening treatment, the bearings are made of SF-1 oil-free lubricating bearings or needle roller bearings, and the seals are made of double-lip nitrile rubber. Make the gear pump stable, wear-resistant, and have a long service life. Using helical gears, the sound will be lower.
