Classification of hydraulic motors
Oct 30, 2018

Hydraulic motor According to its structure type to divide, can be divided into gear type, vane type, plunger type and other type. According to the hydraulic motor rated speed is divided into high speed and low speed two categories. Rated speed higher than 500r/min belongs to high-speed hydraulic motor, the rated speed is lower than 500r/min belongs to the low-speed hydraulic motor. The basic type of high speed hydraulic motor is gear type, screw type, vane type and axial plunger type. Their main characteristics are high speed, small moment of inertia, easy to start and braking, adjustment (speed and commutation) sensitivity. Usually high-speed hydraulic motor output torque is not so called high-speed small torque hydraulic motor. The basic type of low-speed hydraulic motor is radial plunger type, in addition to axial plunger type, vane type and gear type also has low-speed structural type, low-speed hydraulic motor is mainly characterized by large displacement, large volume speed low (sometimes up to a few revolutions per minute or even fraction), so can be directly connected to the work organization; Make the transmission mechanism large for simplification, usually low-speed hydraulic motor output torque is large, so also known as low-speed large torque hydraulic motor.
