Specifiion

 
 
Description
 

Hydraulic piston pump, in particular for hydraulic systems, having a drivable cylinder drum, rotating around an axis in a pump housing, in which the piston cylinder units are arranged on a circle at an offset, wherein the pistons are supported, at least indirectly, on a swash plate at their actuating ends, which is accessible from outside the cylinder drum, and a controlling device is disposed between the swept volumes of the piston cylinder units and a stationary fluid inlet and a stationary fluid discharge of the pump housing, the controlling device having fluid channels for the targeted transfer of fluid from the fluid inlet into the swept volumes and from the swept volumes to the fluid discharge.

 
 
Characteristic

1. The parts constituting the sealing volume are cylindrical plungers and cylinder holes, which are easy to process and can obtain high matching accuracy;
2. Good sealing performance, still high volumetric efficiency under high pressure;
3. The flow rate can be changed only by changing the working stroke of the plunger, which is easy to realize the variable;
4. The main parts in the plunger pump are all subject to compressive stress, and the material strength properties can be fully utilized.
5. Because the plunger pump has high pressure, compact structure, high efficiency and convenient flow adjustment, it is used in systems requiring high pressure, large flow and high power and in occasions where the flow needs to be adjusted, such as gantry planers, broaching machines, hydraulic presses, construction machinery , mining metallurgical machinery, ships have been widely used. According to the arrangement and movement direction of the plunger, the plunger pump can be divided into two egories: radial plunger pump and axial plunger pump. There are two types of plunger pumps in the distribution device, which can be divided into quantitative plunger pumps and variable plunger pumps according to whether the displacement is variable.
