Due to the different hydraulic motors and pumps working conditions, their performance requirements are not the same, so the same type of pump maintenance call between a hydraulic motor and a hydraulic pump, there are still many differences. First hydraulic motor should be able to forward and reverse, which requires that its internal structure symmetry; hydraulic motor speed range required is large enough, especially to its lowest steady speed have certain requirements. Therefore, it is usually by rolling or hydrostatic bearings; secondly because of the hydraulic motor to work under pressure oil input conditions, and therefore does not have to have the self-absorption capacity, but requires some initial sealing hydraulic professional services, in order to provide the necessary start torque. Because of these differences, so that the hydraulic motor and a hydraulic pump is quite similar in structure, but not reversible work. Low speed high torque hydraulic motor can be divided into: radial piston hydraulic motor, hydraulic motor crank rod pump sales calls, swing cylinder type hydraulic motor and cycloid hydraulic motors crank several low speed high torque hydraulic rod. Earlier hydraulic motor application, called Starr made abroad (Staffa) hydraulic motor.
