Abstract

The invention belongs to the technical field of mechanical equipment, and provides a control device for a hydraulic motor. The control device comprises the hydraulic motor, wherein the hydraulic motoris connected with a manual speed regulating device, the manual speed regulating device is connected with a valve control device, and the valve control device is connected with an oil inlet of the hydraulic motor; and the manual speed regulating device can also be connected with an automatic regulating device. According to the control system for the hydraulic motor, control over the output speed of the hydraulic motor is achieved through a pure mechanical structure, and the control system has the advantages of being simple in structure and low in production cost; the hydraulic motor works without depending on a circuit, so that the fault probability is low; an automatic speed regulating device is matched with the manual speed regulating device, when one device goes wrong, the other deviceis started to work, so that the situation that the hydraulic motor cannot normally regulate the speed is avoided, and the working efficiency is not affected; and the speed regulating device of the mechanical structure has the advantages of being simple in troubleshooting, convenient to maintain and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a control device for a hydraulic motor. Background technique [0002] The hydraulic motor is an actuator of the hydraulic system. It converts the hydraulic pressure energy provided by the hydraulic pump into the mechanical energy (torque and speed) of its output shaft. The liquid is the medium for transmitting force and motion; hydraulic motor, also known as oil Motors are widely used in various industries such as injection molding machinery, ships, hoisting machines, engineering machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical industry, port machinery, etc.; The speed regulation of hydraulic motors generally adopts solenoid valves or other electric valves, which are too dependent on electric power. When there is a problem with electric power, the hydraulic motor will not be able to reg...
