How to reduce the working pressure of hydraulic pump in digging machine

First: Improve the design of hydraulic systems. After many arguments, advanced priority valve and load sensing full hydraulic steering gear form are used. The new system can prioritize the distribution of traffic according to the steering requirements, and ensure that the fuel supply is adequate regardless of the size of the load and the speed of the steering wheel. The rest of the system can be supplied to the work unit circuit, eliminating the need for excessive oil supply to the steering circuit. Power loss increases system efficiency, which reduces the hydraulic pressure of excavator work.
Second: Optimizing the design of the digging machine and the shape of the boom cylinder and the hydraulic pump can also reduce the working pressure of the hydraulic system of the digger. With optimized calculations, the boom cylinder uses the standard series 80/4. The displacement of the hydraulic pump was increased from 10ml/r to 14ml/r, and the system set pressure was 14mpa, which satisfied the lift force and speed requirements of the boom cylinder.
Third: In the process of using, attention should also be paid to the correct use and maintenance of the digging machine, adding or replacing hydraulic oil on a regular basis, maintaining the cleanliness of the hydraulic oil, and strengthening daily inspection and maintenance.
