Variable speed hydraulic motor

Variable speed regulating hydraulic motor is a stepless speed regulating function by changing the liquid flow.

Hydraulic motor speed regulating system and speed control method: lifting equipment, the hydraulic motor speed regulating system includes: first hydraulic pump; Hydraulic motors, including descent and uplift; The first reversing valve, connection between the first hydraulic pump and hydraulic motor, oil inlet connected to the output end of the first hydraulic pump, the first work falling oil mouth connected to hydraulic motor, the second working oil outlet connected to the rise of hydraulic motor mouth; The flow control valve is connected to the hydraulic pipe between the first commutation valve and the hydraulic motor to control the hydraulic flow of the uplift. The pressure control mechanism is connected to the control end of the flow control valve to control the opening of the flow control valve; And controller, obtain the hydraulic flow of the first reversing valve, and adjust the opening of the flow control valve according to the hydraulic flow control pressure control mechanism.

Characteristics:

according to the invention, the hydraulic motor speed regulating system can effectively prevent the vibration of the hydraulic motor and improve the safety of the hydraulic motor hoist.
