Description
 

Hydraulic Piston Pump is an important device in the hydraulic system. It has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment. It is widely used in high pressure, large flow and occasions where flow needs to be adjusted. In daily use, it should be maintained in a timely manner in order to make it perform its best function.
The plunger pump that uses the charge pump to supply oil, after 3000 hours of use, the operator needs to check the plunger pump 1-2 times a day to check whether the sound of the hydraulic pump is normal. If it is found that the speed of the hydraulic cylinder decreases or the car is stuffy, the charge pump should be disassembled and checked to check whether the edge of the impeller is scratched and whether the clearance of the internal gear pump is too large. For self-priming plunger pumps, the oil in the hydraulic oil tank should not be lower than the lower limit of the oil mark, and a sufficient amount of hydraulic oil should be maintained. The higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump.

 
 
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.
