The low pressure fluid that another actuator port of motor flows out returns to two position and four-way reversing valves, further with multiple directional control valve
The fluid that oil return opening flows out converges, and the fluid part behind interflow flows to the inlet port of axial plunger pump, makes simultaneously
Closed check valve, remaining part returns to hydraulic oil container after flowing through counterbalance valve, fan-cooled radiator, return filter.
9., according to the using method of the hydraulic-driven corn straw smashing returning device described in claim 7, it is special
Levy and be: low-pressure settings and the measured value of pressure transducer are respectively U0 and U1；The setting of temperature sensor
Value and measured value are respectively T0 and T1；If during the U1-U0 of pressure transducer > 0, illustrate that oil return circuit is in
Abnormal operation, controller is to one misfire signals of electromotor；If during the T1-T0 of temperature sensor > 0,
Illustrating that fuel tank cooling system is in abnormal operation, controller is to one misfire signals of electromotor.
