2, displacement and flow (1) per revolution displacement hydraulic pump V, the volume of liquid discharged by sealed volume changes calculated geometry called displacement pump. Displacement hydraulic pump can be adjusted is called a variable pump; pump displacement can not be adjusted is called a metering pump. (2) Theoretical Theoretical flow refers to the flow rate at the leakage flow rate of the hydraulic pump without considering the conditions, the liquid volume discharged per unit time. If the hydraulic pump displacement hydraulic motor repair V, which spindle speed n, the theoretical flow rate of the hydraulic pump is qt qt = Vn where V is the displacement of the hydraulic pump (m3 / r) of the hydraulic motor is detected, n is the liquid volume spindle speed (r / s) (3) actual flow qt hydraulic conditions within a particular hydraulic motors overhaul, discharge per unit time is called the actual flow rate, which is equal to the theoretical flow qt minus leakage and compression loss ql flow after the hydraulic motor, namely q = qt a ql (4) qn nominal flow under normal operating conditions, the test standards (such as at rated pressure and rated speed) must ensure that traffic. CY14-1B type axial piston pump / motor, is the use of oil pan with oil, cylinder rotating axial piston pump. Because between the shoe and the variable head, using a hydrostatic equilibrium structures with oil pan and cylinder block, so compared to other types of pumps, it has a simple structure, small size, high efficiency, long life, light weight , self-absorption ability and so on. It is suitable for machine tools, forging, smelting, engineering, mining and other machinery, and other hydraulic transmission system. Just replace the pump motor with the oil pan can also be made using a hydraulic motor. Repair of hydraulic motors, hydraulic Jing Chong price (certification), a hydraulic motor provided by the Jinan Jing Chong Hydraulic Machinery Co., Ltd ..
