Aluminum alloy, high strength, corrosion resistance, light weight, suitable for a variety of environmental operations. Two-speed feature reduces the pressure to maintain the number of imported hydraulic motors in the low pressure chamber load quickly in hard state hydraulic motor import services immediately converted into pressure, shorten cycle time per job. Pump works by the movement to bring change in the volume of the pump chamber hydraulic motor import agent, thereby compressing the fluid pressure of the fluid can have. The condition is that the pump must have the seal cavity volume change. Equipped with a pressure regulating valve, can be adjusted to control and set the operating pressure. Hydraulic motor and the load pressure is increased and then the hydraulic oil is compressed by being driven, 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 end of the spring pushing at a constant speed v0 (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 import agent, crystal create a hydraulic (certified), hydraulic motor from Jinan Jing Chong hydraulic machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd. (www.jnjcyy.com) (www.jnjcyy.com) Shandong Jinan, mining machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In the crystal to create a hydraulic leadership with the staff warmly welcome all inquiries negotiations to create the crystal to create a better future for the hydraulic.
