Road roller machine hydraulic piston pumps easy to operate
Hydraulic piston pumps basic information:
Hydraulic piston pump is an important device in the hydraulic system. Hydraulic piston pump relies on the reciprocating motion of the plunger in the cylinder body to change the volume of the sealed working chamber to achieve oil absorption and oil pressure.
Hydraulic piston pumps of road roller features:
Hydraulic 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 piston pumps operated mechanically, the servo displacement can control and keep the angle of swash plate and pump displacement.
