During the use of the OMR orbital motor, issues such as weak operation and abnormal heating often occur, directly affecting equipment work efficiency. Based on years of technological accumulation and user service experience, HANJIU Technology hased troubleshooting ideas and solutions for common faults of the OMR orbital motor.
1. OMR orbital motor operates weakly, and speed significantly drops under load
If the OMR orbital motor runs normally without load but its speed drops or it cannot drive the load under load, this usually points to excessive internal leakage. The main causes include: the clearance between the stator body and rotor being too large, or severe wear of the needle pin, leading to high-pressure oil leakage; wear on the mating surface between the output shaft and the housing can also increase internal leakage. Poor hydraulic oil cleanliness accelerates this wear.
During troubleshooting, first check whether the system pressure meets the standard, ruling out faults in the hydraulic pump or relief valve. If the pressure is normal, the OMR orbital motor needs to be disassembled to measure the clearances of core components. HANJIU Technology recommends regularly checking oil cleanliness and replacing hydraulic oil filters as specified to reduce wear at the source. For worn components, HANJIU can provide OEM-quality needle pins, housing, and other parts, and offer professional guidance for replacement to restore performance.
2. The OMR Orbital Motor heats abnormally and the shell temperature is too high
The OMR Orbital Motor is running at an abnormal temperature and the housing is hot, indicating that energy is converted into heat at an abnormal position. Common causes include: long-term overload operation; the back pressure of oil return is too high; Internal wear leads to increased internal leakage, and high-pressure oil generates a lot of heat through the leak channel; Poor heat dissipation conditions.
During the investigation, check whether the working pressure exceeds the rated value and confirm whether the oil return back pressure is within the allowable range. Monitor the oil temperature, if it exceeds 80°C, stop immediately. HANJIU Technology recommends setting up a cooling device reasonably to ensure that the outlet pipe is connected correctly, which can not only take away wear pollutants but also play a cooling role. If it is confirmed that the heat is caused by internal wear, the HANJIU technical service team can provide professional inspection and maintenance solutions.
3. The OMR orbital motor does not rotate or runs unsmoothly
The OMR Orbital Motor fails to start or "crawls" (one card at a time, sometimes it goes and sometimes stops), which may be due to insufficient system pressure; Internal jamming, such as small gap between parts, foreign objects entering or severe wear; Insufficient oil flow, blockage of oil circuit or reverse connection of oil inlet and outlet. Crawling is often associated with improper mating gaps.
During the investigation, first confirm whether the hydraulic pump is supplied with oil normally and whether the pressure is up to standard. Check whether the oil circuit connection is correct and whether the filter is clogged. If the external factors are normal, the OMR Orbital Motor needs to be disassembled and inspected. HANJIU Technology reminds users that they should strictly follow the technical specifications during installation, and tighten the fastening screws according to the specified torque to avoid jamming caused by improper assembly.
As a professional enterprise deeply involved in the field of fluid power, HANJIU Technology not only provides reliable OMR orbital motors, but also establishes a complete technical support and after-sales service system. The company implements strict quality control in the R&D and manufacturing process, and each OMR Orbital motor is tested for performance before leaving the factory. When users encounter use faults, HANJIU's professional team can provide remote diagnosis or on-site service, and supply original quality repair parts. Choosing HANJIUomr orbital motor means choosing a reliable guarantee throughout the entire life cycle of the product.
