Troubleshooting of the hydraulic motor (1) output torque is not enough ① roller cylindrical housing bore and loose with the original pump, or cause wear and tear after use into the oil chamber of the pressure oil drain back oil chamber (oil chamber) hydraulic pumps, internal leakage increases, this time should be accompanied by brush or roller reworked. ② rotor blade root round wear, internal leakage volume. ③ dirt and roller blades stuck. ④ between the roller and roller blade shaft due to machining precision and assembly precision is not good, so great friction roller pump maintenance, the oil film between the outer leaves and the root circle is cut broken, causing thousands of friction. B series piston pump | motor Overview folded edit this section with low noise, high efficiency, small size, light weight, long life, complete the form variable, low energy consumption, can be adapted to a variety of hydraulic characteristics in a variety of media, such as a series of fixed machinery and mobile hydraulic drive system has been widely used. Its installation and connection dimensions metric and imperial two kinds. Furthermore, in order to meet user needs, as well as British and shaft only fitting opening stretch, mixing metric mounting oil port. B series piston pump | Motor Series models with the following products: variable piston pump, variable motor, fixed displacement motor, quantitative piston.
