Hydraulic control system for improving energy saving performance of loader and control method of hydraulic control system
The invention discloses a quantitative work hydraulic system intelligent control system for a loader. The system comprises a hydraulic oil tank, a work pump, a distribution valve, a pilot pump, an intelligent control module, a pilot valve, a rotating bucket oil cylinder and a boom cylinder. The intelligent control module is mainly composed of a first solenoid valve, a second solenoid valve, a first pressure sensor, a second pressure sensor and a controller. An electronic control valve set is integrated by the intelligent control module, and under the condition that the module is not used or the function of the module fails, the manner that a whole machine work hydraulic system works through a traditional control mode is not affected. When the module is used for working, the one-key operation function of the module is adopted, seamless switching between the work device bucket folding movement and the movable arm lifting movement can be intelligently achieved, and automatic unloading of the work hydraulic system is finally achieved. Meanwhile, the labor intensity of loader operating personnel is greatly lowered. The effects that the work hydraulic system saves energy and is efficient, and the combination work state traction force of the loader is increased are achieved.
