Highland hydraulic transmission piston pump working principle
Hydraulic transmission piston pumps introduction:
Hydraulic transmission piston pump with big displacement 110ml/r, high performance and high efficiency, could work fast and well. Nowadays hydraulic transmission piston pump is very popular all over the world. It is used for driving mobile machines like harvesters and transit mixer etc. The control system of hydraulic transmission piston pump can be hydro mechanical control system.
Hydraulic transmission piston pumps features:
Hydraulic transmission piston pumps are well engineered and easy to handle.
Bearings of piston pumps are all tapered roller bearing, which can load heavy external axial forces.
When hydraulic transmission piston pumps operate mechanically, the servo displacement can control and keep the angle of swash plate and pump displacement.
