[0002] A hydraulic motor is an actuator in a hydraulic system. It converts the liquid pressure energy provided by a hydraulic pump into mechanical energy (torque and speed) of its output shaft. Liquid is the medium for transmitting force and motion. Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, engineering machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, marine machinery, petrochemical industry, port machinery, etc. Hydraulic motors and their front end covers tend to generate a lot of heat during operation, affecting the operation of the motor, so they need to be cooled and dissipated.
