Advantages Of Hydraulic Piston Pumps

First of all, the parts that constitute the sealing volume are cylindrical plungers and cylinder holes, which are convenient for processing, can obtain high matching accuracy, good sealing performance, and still have high volumetric efficiency in high-pressure work;
Second, the flow rate can be changed by simply changing the working stroke of the plunger, and it is easy to realize the variable;
Third, the main parts in the plunger pump are subjected to compressive stress, and the material strength performance can be fully utilized.
Due to the high pressure, compact structure, high efficiency and convenient flow adjustment of the plunger pump, it is widely used in systems that require high pressure, large flow and high power and occasions where flow needs to be adjusted, such as gantry planers, broaching machines, hydraulic presses, engineering machinery, mining metallurgical machinery, and ships. Plunger pump according to the arrangement and movement direction of the plunger, can be divided into two categories: radial piston pump and axial piston pump, according to the type of distribution device can be divided into two categories of distribution piston pump with gap seal type distribution sub-piston pump and valve distribution device plunger pump, according to whether the displacement is variable into quantitative plunger pump and variable plunger pump.
