plunger pump

Rexroth plunger pump is a hydraulic pump which depends on the reciprocating movement of the plunger in the cylinder block to achieve the change of the sealing volume to absorb oil and press oil. Compared with the gear pump and the vane pump, this pump has many advantages. First of all, the parts that constitute the sealing volume are cylindrical plunger and cylinder hole, which are easy to process, can get higher matching accuracy, good sealing performance, and still have higher volume efficiency in high pressure work; Second, the flow can be changed only by changing the working stroke of the plunger, which is easy to realize the variable; Third, the main parts of the piston pump are under compression stress, the strength of the material can be fully utilized. Due to the high pressure of the piston pump, compact structure, high efficiency, convenient flow regulation, so in the need of high pressure, large flow, high power system and flow need to adjust the occasion, such as gantry planer, broaching machine, hydraulic press, engineering machinery, mining metallurgical machinery, ships have been widely used. According to the plunger arrangement and direction of movement, the plunger pump can be divided into radial piston pump and axial piston pump two categorie
