How to deal with Axial hydraulic piston pump flow insufficient

Piston pump is a very important power element in the whole hydraulic system, the working efficiency will be seriously affected after the failure, then how to deal with the axial hydraulic piston pump flow shortage? If you are very confused, please read the hydraulic plunger pump manufacturers detailed introduction!

 

First, the flow rate of the variable pump can be adjusted by changing the Angle of the tilting disc element. When the position of the plunger reaches 0° to 180°, the volume of the plunger cylinder becomes larger, and the oil suction port of the oil distribution pan will flow into the liquid to the cylinder, thereby increasing the flow. When the position of plunger reaches 180° to 360°, the volume of plunger cylinder decreases, and the flow rate decreases. For the quantitative pump, the tilt Angle is fixed, is not through this method to regulate the flow.

 

Secondly, what are the causes of insufficient piston pump flow? 1. Before running the oil pump, the oil is not filled with liquid and some air is left in it; 2. The oil level of the oil tank is too low; 3. Blockage or leakage of tubing or oil filter and other components; 4. The center spring of the oil pump is not elastic enough or broken, and the plunger cannot return normally; 5. Poor sealing between cylinder block and oil distribution plate element; 6, variable axial piston pump variable Angle is too small, you can adjust the Angle to change the insufficient flow; 7. Low oil temperature leads to decreased oil viscosity and internal leakage of piston pump. 8. Cylinder block, oil distribution plate, cylinder block and other components wear seriously, causing oil leakage;

 

As long as follow the steps above, the axial piston pump flow insufficient problem will be easily solved. Hope these content can bring practical help to everybody!
