A2F6.1 piston pump / motor: A2F6.1 quantitative structure of the axial piston bent axis piston pump maintenance cone with a fixed displacement pump used for hydrostatic transmission in open or closed loop or motor. When used as a quantitative piston pump domestic pump, flow proportional to the drive speed and displacement. Quantitative piston pump when working as a motor test, the output speed and inversely proportional to flow with the displacement. Quantitative piston pump with the pressure drop between the output torque and the low pressure side and high pressure side to increase. Piston oil spill following main reasons: (1) the spindle shaft seal is damaged or defective, scratches; (2) internal leakage is too large, resulting in increased pressure oil seals, but will seal damage or out; (3) vent pipe too small for too long, so that the seal leakage; (4) external pump tubing loose fittings injury, aging or seal cracks; (5) variable adjustment mechanism loose bolts, seal is broken; (6) Cast iron pump casing There are bad blisters or welding. Pump maintenance, crystal creating hydraulic (certified), the hydraulic pump by 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.
