The basic types of low-speed hydraulic motor is a radial piston hydraulic motor sales calls, in addition to the axial piston, vane and gear type is also a low-structure type, the main features of low-displacement hydraulic motor is large, bulky low speed (sometimes even turn up a few tenths of revolutions per minute), it can be directly connected with the work of agencies; no decelerating device professional aftermarket hydraulic motor that greatly simplify the transmission mechanism, usually a larger output torque at low speed hydraulic motor , it is also known as the low speed high torque hydraulic motor. Hydraulic motor and the load pressure is increased and then the hydraulic oil is compressed by being pushed professional maintenance hydraulic motors, therefore, is illustrated in Figure 4-1 (a) shows the physical model shown in the low speed region of the hydraulic motor working process: the uniform velocity v0 Push one end of the spring (equivalent to work under high pressure incompressible media), so that an object of mass m (equivalent to the motor and load mass moment of inertia) to overcome the "negative characteristics" of the frictional resistance movement. When the object is stationary or very slow resistance, compression spring constant increase thrust. Hydraulic motor to create hydraulic pressure sales calls _ Crystal (certified) _ hydraulic motors is provided by Hydraulic Machinery Co., Ltd. Jinan Jing Chong. Jinan Jing Chong Hydraulic Machinery Co., Ltd.
