Ram Pump - Advantages
Plunger pump is a hydraulic pump that absorbs oil and presses oil through the change of sealing volume caused by the reciprocating movement of plunger in cylinder body. Compared with gear pump and blade pump, this kind of pump has many advantages.
First of all, the parts constituting the sealing volume are cylindrical plunger and cylinder hole, which are easy to process and can obtain high precision of cooperation and good sealing performance.
Secondly, the flow can be changed simply by changing the working stroke of the plunger.
Third, the main parts of plunger pump are subjected to compressive stress, and the strength of materials can be fully utilized.
Because of the high pressure, compact structure, high efficiency and convenient flow adjustment of plunger pump, it is widely used in high pressure, high flow and high power systems, such as longmen planer, broaching machine, hydraulic press, engineering machinery, mining metallurgy machinery and ships. The plunger pump can be divided into radial piston pump and axial piston pump according to the arrangement of the plunger and the movement direction of the piston. According to the type of the flow distribution device, it can be divided into two categories: the piston pump with clearance seal type and the plunger pump with valve distribution device.
