1. Improve system planning. It has been repeatedly proved that the leading priority valve and load sensing full plunger steering gear are finally selected. The new system can give priority to the distribution of flow according to the steering demand. No matter the size of the load and the concave convex speed of the steering wheel, it can ensure sufficient oil supply. Some of the rest can be supplied to the operating device circuit, and then the loss of success rate caused by excessive oil supply in the steering circuit is eliminated, The system power is improved and the working pressure of the plunger pump is reduced.
2. Optimize and plan the appearance of boom cylinder and plunger pump to reduce the operating pressure of the system. After optimization calculation, the boom oil cylinder selects the specification series 80 / 4. The displacement of the plunger pump has increased from 10ml / R to 14ml / R, and the set pressure of the system is 14MPa, which meets the lifting force and speed requirements of the boom cylinder.
3. In the process of application, pay attention to the accurate application and protection of the loader, increase or replace the hydraulic oil regularly, adhere to the cleanliness of the oil, and strengthen the inspection and protection at ordinary times.
