Abstract

The invention relates to a load sensitive hydraulic system. The load sensitive hydraulic system solves the problem that an existing load sensitive hydraulic system is poor in adaptability due to the change of working conditions on a machine. The load sensitive hydraulic system comprises a two-position three-way solenoid valve and a fixed differential reducing valve, wherein a first oil port of thetwo-position three-way solenoid valve is connected with a load feedback port of a load-sensitive control valve, a third oil port is connected with a flow control valve control port on a load-sensitive variable pump, a second oil port is connected with a flow control valve control port on a load-sensitive variable pump through the fixed differential reducing valve, and the first oil port of the two-position three-way solenoid valve communicates with one of the second oil port or the third oil port. According to the load sensitive hydraulic system, the load feedback pressure transmitted by theload sensitive control valve is controlled, so that in different working conditions, the opening degree of the valve opening of the load sensitive control valve is the same, but the flow output by theload sensitive variable pump is different, so that the hydraulic system and the corresponding working condition are more suitable for matching, and the adaptability of the machine in different working conditions is improved.

Description

technical field [0001] The present invention relates to a hydraulic system, and more particularly, to a load sensing hydraulic system. Background technique [0002] The load-sensing hydraulic system is mainly composed of load-sensing variable pump 1, load-sensing control valve 2 and hydraulic actuator 3. In this system, the outlet of the load-sensing variable pump is connected to the inlet of the load-sensing control valve, and the load of the load-sensing control valve The feedback port is connected to the control port of the flow control valve 11 on the load sensing variable pump 1 . [0003] The load-sensing hydraulic system controls the flow output of the load-sensing variable pump through the valve opening of the load-sensing control valve. The larger the valve opening is, the greater the output flow of the pump is, otherwise the output flow decreases. The working principle is as follows: figure 1 As shown, the outlet of the load sensing variable pump (port P) is conne...
