Due to the pressure of the hydraulic motor vane oil effect, the uneven rotor to produce torque. Vane-type hydraulic motor output torque and displacement hydraulic motor and hydraulic motor oil out of the pressure difference between the mouth related to its speed by the input flow of the hydraulic motor to determine the size. As the hydraulic motor is generally reversible hydraulic motor can request a proxy (domestic), so vane type hydraulic motor to the radial placement. In order to pass the blade root is always pressure oil, in return, should set up a one-way valve motors finishing (domestic) pressure on the oil chamber Walter blade root access, in order to ensure that the hydraulic vane motor oil pressure after Walter can normal start, and the tip of the blade must be in close contact with the inner surface of the stator, in order to ensure a good seal of the hydraulic motor maintenance (domestic), so the blade root should be set the preload spring. Hypocycloidal hydraulic motor can edit the ring fixed to the case together, into the oil from the oil port push the rotor revolves around a central point. This slow rotation of the rotor shaft drives the output spline become cycloid hydraulic motor. After this initial orbital motors come, after decades of evolution, another notion of motor also begins to form. This motor is installed in the built-in ring gear rollers. Motor having a roller can provide a high starting and running torque, roller reducing friction, thereby improving efficiency, even at low rotational speed of the output shaft also can produce stable output. By changing the direction of the input and output flow rapidly reversing the motor, and the like to generate a torque value in both directions. Each series has a variety of motor displacement of selected candidates to meet a variety of speed and torque requirements. Hydraulic motor finishing (domestic), 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.
