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.
