Hydraulic piston pumps basic information:
The piston pump is a hydraulic pump that relies on the
reciprocating motion of the piston in the cylinder to cause the
change of the sealing volume to achieve oil suction and oil
pressure. This pump has many advantages.
First of all, the parts constituting the sealed volume are
cylindrical plungers and cylinder holes, which are easy to process,
can obtain high matching accuracy, have good sealing performance,
and still have high volumetric efficiency under high pressure.
Second, the flow rate can be changed only by changing the working
stroke of the piston, and it is easy to realize the variable;
Third, the main parts in the piston pump are all subject to
compressive stress, and the material strength properties can be
fully utilized.
Because the piston pump has high pressure, compact structure, high
efficiency and convenient flow adjustment, it can be used in
systems that require high pressure, large flow, and high power and
in occasions where the flow needs to be adjusted, such as
agricultural machinery, construction machinery, mining and
metallurgical machinery, and shipbuilding industry etc other wide
range of applications.
