Differences between hydraulic pumps, reducers, and motors
Thread Content
I hear people talk about pump motors and reducers all day long – what’s the difference between them?
1. The hydraulic pump is the power element of a hydraulic system; it is driven by an engine or electric motor, draws in oil from the hydraulic tank, creates pressurized oil, and sends it to the actuating elements. Hydraulic pumps are classified by structure into gear pumps, piston pumps, vane pumps, and screw pumps. 2. Reducers serve to match rotational speeds and transmit torque between the prime mover and the working machine or actuator, and they are widely used in modern machinery. Based on their application, reducers can be divided into two main categories: general-purpose reducers and specialized reducers. The design, manufacturing, and usage characteristics of these two types differ from each other. 3. “Motor”: It is the transliteration of the English word motor, referring to electric motors or engines. The working principle involves a current-carrying coil being subjected to a force in a magnetic field, which causes it to rotate and thus drives the starter rotor to spin; the pinion on the rotor in turn causes the engine’s flywheel to rotate.
