The Motor Orbital OMP features a stable structure and a low failure rate; however, prolonged continuous operation or improper maintenance can lead to minor internal leaks and reduced power output. These issues manifest as normal operation under no-load conditions, a drop in speed under load, and insufficient driving force, all of which affect operational efficiency. Such failures are typically caused by improper use or maintenance. Based on extensive practical experience, Hanjiu Company has compiled professional analyses of the root causes of these failures, along with repair and maintenance solutions, to help users quickly resolve equipment issues.
The primary causes of increased internal leakage and power loss in the Motor Orbital OMP are mainly attributed to two factors: seal aging and minor wear. The OMP series features a compact, lightweight design with precision-engineered, miniature internal sealing components. When subjected to prolonged hydraulic pressure surges and temperature fluctuations, these seals can age and lose elasticity, resulting in reduced oil circuit integrity and minor internal oil leakage. At the same time, prolonged use of the equipment without timely replacement of the hydraulic fluid allows fine impurities to accumulate in the fluid, causing slight wear on the meshing surfaces of the motor’s stator and rotor as well as in the distribution clearances. This results in reduced fitting precision and a gradual increase in internal leakage, ultimately manifesting as insufficient power and weak load performance. All Motor Orbital OMP units manufactured by Hanjiu undergo rigorous sealing and pressure testing before leaving the factory. They incorporate highly wear-resistant sealing materials, which reduce the likelihood of internal leakage failures at the source and ensure consistent product quality.
For issues such as minor internal leakage and reduced power in the Motor Orbital OMP, a targeted, simple repair solution can be implemented to quickly restore equipment performance without replacing the entire unit. First, after shutting down the machine and relieving pressure, disassemble the motor’s outer end cap and inspect the internal sealing components, such as gaskets and oil seals. Directly replace any sealing parts that are aged, deformed, or hardened—this is the most critical and effective step in resolving minor internal leakage; Second, clean oil residue and fine impurities from the motor’s internal chamber and the surfaces of the stator and rotor, and check the meshing surfaces for minor wear. If the wear is minor, the unit can be reassembled and put back into service after cleaning; Finally, replace the hydraulic oil with a new, compliant fluid and install a new system filter. After reassembly, conduct a no-load test run, then gradually increase pressure to test the load power. This will completely resolve the issues of power loss and internal leakage, significantly reducing equipment maintenance costs.
Proper daily maintenance is key to preventing internal leakage failures in the Motor Orbital OMP and extending the equipment’s service life. Compared to repairs after a failure occurs, proactive prevention is more effective in ensuring the long-term, stable operation of the equipment. During daily use, strictly monitor the cleanliness and service life of the hydraulic oil. Never use poor-quality hydraulic oil that is cloudy, degraded, or contains impurities. Replace system filters regularly to prevent impurities from causing wear on internal precision components. At the same time, avoid prolonged operation under overload or excessive pressure to reduce pressure-induced wear on sealing components. Before restarting idle equipment, check the oil circuit pressure and the condition of the seals in advance to promptly identify and address potential hazards. Routine, simple maintenance can effectively preserve motor performance and ensure stable power output over the long term.
