Hydraulic piston pumps basic information:
Hydraulic piston pump is an important device in the hydraulic system. It 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. Piston pumps have the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment. They are widely used in occasions where high pressure, large flow and flow need to be adjusted.

Hydraulic oil notice of hydraulic piston pumps:
The higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump.
Hydraulic oil:
Generally speaking, the replacement time of hydraulic oil of sealed oil tank system is 2000hours. If the hydraulic oil is contaminated or other outside material bears abnormal running condition, the hydraulic oil should be changed often.
Hydraulic oil in the open oil tank system should be changed every 500hours. For different vehicle, the measures should determined by specific design and operational experience.
