The piston pump is an important device in the hydraulic system. It relies on the reciprocating movement of the piston in the cylinder block to change the volume of the sealed working chamber to achieve oil suction and pressure. Its made of cast iron usually, and the piston pump is among the most durably designed pumps available.
The axial piston pump is a swash-plate type axial piston pump that uses an oil valve plate to distribute oil, the cylinder body rotates, and the variable head is used for variable displacement.
The typical axial piston pump consists of a cylinder block or barrel, piston shoe, valve plate, retainer plate, ball guide, swash plate. The pump adopts the optimum oil film thickness design of static hydraulic balance, which makes the cylinder block and valve plate, piston shoes and variable head operate under pure liquid friction. The axial piston pump has a variety of variable situations to meet the requirements of users. It is widely used in machine tool forging, metallurgy, engineering, mining, shipping, and other machinery and other hydraulic transmission systems.
The axial piston pump uses the volume change produced by the reciprocating motion of the piston parallel to the drive shaft in the piston hole to work. As the piston shoes and the hole are round parts, they can be processed with high precision, so they have the advantages of high volumetric efficiency, stable operation, good flow uniformity, low noise, and high working pressure.
