How to control the flow rate of a piston pump

(1) Improve plunger system planning. After repeated proven, the final selection of priority valve and load sensing full piston diverter, the new system can be according to the steering demand, priority distribution of flow to it, regardless of the size of the load, steering wheel speed concave and convex can ensure sufficient oil supply, the remaining some can be fully supplied to the operating device circuit use, and then eliminate the power loss caused by excessive oil supply to the steering circuit, improve the system power, reduce the operating pressure of the piston pump.
(2) Optimize the appearance of the boom cylinder and plunger pump to reduce the operating pressure of the system. After optimization calculation, the boom cylinder is selected as the standard series 80/4. The displacement of the piston pump has been improved from 10ml/r to 14ml/r, and the system has a set pressure of 14MPa, which meets the lifting force and speed requirements of the boom cylinder.
(3) In the process of use, we should also pay attention to the accurate use and protection of the loader, regularly increase or replace the hydraulic oil, adhere to the cleanliness of the oil, and strengthen the usual inspection and protection.
