At equipment maintenance sites, we often see situations like this: two motors of the same model of orbital hydraulic motor are put into use at the same time; one has been operating smoothly for eight years, while the other develops oil leaks, abnormal noises, and even seizure after just eight months. More than 60% of early failures are not due to the product itself, but to overlooked details during installation and maintenance. As a professional developer and manufacturer of orbital hydraulic motors, HANJIU, drawing on years of industry experience, has compiled six practical guidelines to help you avoid installation and maintenance mistakes and maximize the performance of your orbital hydraulic motor.
The first thing is to clean and inspect before installation to eliminate the risk of impurities. Before installation, thoroughly clean the motor interface, connecting components, and hydraulic pipelines to prevent iron filings, dust, and other impurities from entering the motor. Otherwise, they will wear the rotor and stator, and seals, causing oil leakage and power loss. At the same time, check if the motor's appearance is damaged, if the seals are intact, and if the pipelines are unobstructed. Only after confirming there is no damage or blockage should the installation proceed. HANJIU Company reminds that this step may seem simple, but it is key to avoiding future failures and is also the part most easily overlooked by users.
The second thing is precise alignment, avoiding uneven force. When installing the orbital hydraulic motor, the output shaft and the equipment drive shaft must be precisely aligned, and any deviation should be controlled within a reasonable range. Forcing them together is strictly prohibited. If the alignment deviation is too large, it will cause uneven stress on the motor bearing, and long-term operation can lead to shaft wear, increased vibration, and in severe cases, motor burnout. It is recommended to use professional alignment tools to ensure installation accuracy and extend the motor's service life.
The third thing is strictly controlling the cleanliness and type of hydraulic oil to match the hydraulic system. The orbital hydraulic motor has high requirements for oil cleanliness; if the oil contains impurities, it can seriously damage the internal distribution structure and transmission components. At the same time, it is necessary to select a compatible hydraulic oil type. Different operating conditions require oils with corresponding viscosities to avoid reduced motor efficiency and overheating damage due to incompatible oil.
The fourth matter is to reasonably set the installation torque to avoid overtightening or loosening. The torque of the connecting bolts must be strictly set according to the manual requirements; overtightening can cause component deformation, while loosening can lead to looseness and leakage, affecting the normal operation of the motor.
The fifth matter is to regularly check the oil condition and replace and maintain it in a timely manner. During daily use, it is necessary to regularly check the color, viscosity, and impurity content of the hydraulic oil. If the oil turns black, cloudy, or has an abnormal odor, it should be replaced immediately, and the oil tank and pipelines should be cleaned; meanwhile, check the oil level to ensure it is within the prescribed range to avoid operation under low oil conditions.
The sixth matter is that shutdown maintenance is essential, and moisture and dust prevention should be done properly. When the equipment is shut down for a long time, the hydraulic oil in the motor should be discharged, the motor surface cleaned, and moisture and dust protection measures implemented to prevent internal components from rusting or being damaged.
In addition to mastering the six points mentioned above, you should also be vigilant against these common mistakes: forcibly connecting during installation, neglecting fluid cleanliness, arbitrarily changing torque settings, not replacing hydraulic oil for a long time, and not performing protection after shutdown. These behaviors can significantly shorten the service life of the orbital hydraulic motor.
