Different analytical methods have their different characteristics and performance of the hydraulic motor repair, but all have one thing in common, that they are generally controlled by comparison to analyze and explain the problem. It is through the same or a different period indicators compare various indicators of control was reflected in the number of how many, the quality of the pros and cons, the level of efficiency, size, and so the pace of development of the hydraulic motor to detect consumption in order to make identification under the judge to provide conclusive evidence of information. In addition to the hydraulic motor, the oil estuary, as well as a separate drain port; pump generally only into and out of the oil port (except axial piston pump), the inner leak fluid communication with the inlet. 4) The volumetric efficiency is lower than the hydraulic motor pump; usually relatively high operating speed of the hydraulic pump, hydraulic motor and lower output speed. In addition, the gear pump suction port large drain port small hydraulic motor repair, and suction gear hydraulic motors, the discharge port of the same size; the number of teeth of the gear motor more than the number of teeth of the gear pump; vane pump shall be inclined installation, The blade radial vane motor installation; vane motor is to rely on the roots of camel spring, it is pressed against the surface of the stator, and the vane pump is to rely on the roots of the pressure of hydraulic oil and centrifugal force pressed on the surface of the stator motor testing, crystal creating hydraulic assurance (certification), a hydraulic motor provided by the Jinan Jing Chong Hydraulic Machinery Co., Ltd .. 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 creating hydraulic leadership with the staff warmly welcome all inquiries negotiations to create the crystal creating hydraulic better future.
