Q hydraulic pressure on the plunger equilibrium (domestic) pump maintenance maintenance, and Q is the center of the plunger of the cylinder produces a torque motor drive shaft rotates counterclockwise. Instantaneous total axial piston motor torque generated is pulsating. If you change the motor oil pressure input direction, the motor shaft rotates clockwise. A swash plate angle changes, ie changes in displacement hydraulic pump, not only affects the torque of the motor, and the impact of its speed and direction. Swash plate angle the greater torque is generated, the lower the speed. Hydraulic transmission of hydraulic pumps and motors are relying on the work product of the volume change and work. So, to say the pump can be used as a motor, the motor can be used for pump. In fact, not the same working conditions as a result of both, in order to better play to their performance (domestic) hydraulic refinement, there are differences in the structure, it is not universal. Hydraulic pumps and motors working principle is reversible, theoretically have the same input and output mathematical relationship; (domestic) pump finishing | crystal create a hydraulic (certified) | pump 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.
