Hydraulic motor type


A hydraulic motor is a device that converts the pressure energy of a liquid into mechanical energy. Hydraulic motors have the following characteristics, first of all, hydraulic motors generally require symmetry in the internal structure; Secondly, it is necessary to work normally in a wide range of speeds, usually we will use hydraulic bearings or hydrostatic bearings; Hydraulic motors must also have a large starting torque.


Hydraulic motors are mainly of the following types according to different classification standards. According to the different rated speed, it can be divided into two kinds of high speed and low speed, generally the rated speed higher than 500r/min belongs to the high-speed hydraulic motor, and vice versa belongs to the low-speed hydraulic motor. High-speed hydraulic motor is characterized by high speed, small moment of inertia and easy to start and brake; It is also highly sensitive when regulating speed and commutation. The main characteristics of low-speed hydraulic motor are large displacement, large volume and low speed, so it can be connected with the transmission mechanism without the need for a deceleration device, which can make the transmission mechanism think simplified and more efficient.


According to the structural type of hydraulic motor, it can be mainly divided into Orbital type, gear type, vane type, plunger type and other types. Gear hydraulic motor mainly has the advantages of small size, light weight, good self-priming performance, and convenient maintenance; However, it is a bit noisy, and there are also disadvantages such as large pressure and flow pulsation, volumetric efficiency and low input pressure. Blade hydraulic motor spoilers are characterized by small size, uniform flow, stable operation and low noise; However, its low-speed stability is poor, and the cleanliness of the oil pressure is high. The advantages of plunger hydraulic motor are high pressure resistance, high efficiency, high transmission power, wide speed range and long life; Its disadvantages are demanding requirements for the cleanliness of the working medium, complex structure and high price, and difficult maintenance.


In short, all kinds of hydraulic motors have their own strengths and weaknesses, which need to be selected according to individual application scenarios and needs. If you are not sure about the type of hydraulic motor, you can log on to the official website of Hanjiu Company.
