A radial piston hydraulic motor is a hydraulic motor that uses radially distributed plungers to rotate or reciprocate in the cylinder to transfer energy and thereby output torque and speed. It usually consists of a cylinder, plunger, distribution shaft, and seals. Radial piston hydraulic motors are widely used in various industrial fields, such as shipbuilding, mining, petroleum, and chemical industries. In these fields, it is used to drive various mechanical equipment, such as conveyor belts, presses, ship propellers, etc. Next, ATO will explain to you the knowledge of troubleshooting radial piston hydraulic motors.
