The motor orbital is the core of the machine’s power system. Many users commonly encounter issues such as reduced power, stuttering at low speeds, minor oil leaks, and premature failure. While most people mistakenly attribute these problems to product quality, they are actually caused by improper daily use and inadequate maintenance. Hanjiu is a manufacturer specializing in the R&D, production, and after-sales service of Motor Orbital units. With a complete production line, precision testing equipment, and years of hands-on field service experience, we have a deep understanding of ordinary users’ daily operating habits and maintenance shortcomings. Based on real-world usage data, Hanjiu has developed a comprehensive, easy-to-implement daily maintenance plan to help users reduce repairs, minimize downtime, and extend the service life of their motors.
Throughout the daily operation of the motor orbital, meticulous management of hydraulic fluid is the most fundamental and most effective maintenance measure for directly extending the motor’s service life—and it is also a key maintenance detail that Hanjiu Company emphasizes in every after-sales guidance session. For ordinary users, hydraulic fluid is the motor’s “blood”; 90% of issues encountered during daily operations—such as wear, jamming, internal leakage, and insufficient power—are related to poor fluid condition. As part of routine maintenance, users must consistently perform regular visual inspections, replace the fluid on schedule, and select the appropriate fluid type according to specifications. Before starting work each day, briefly check the color and clarity of the hydraulic fluid. If the fluid appears black, cloudy, contains fine metal particles, or has turned milky white due to emulsification, the machine must be shut down immediately for a fluid change. Never continue operation under such conditions to prevent impurities from scratching the motor’s internal precision stator, rotor, and distribution mechanisms, which could cause permanent damage. At the same time, it is essential to use standard hydraulic oil with the appropriate viscosity for the equipment’s operating conditions. Mixing oils of different brands or grades is strictly prohibited to prevent oil degradation, gumming, and blockage of the oil passages. Every motor shipped by Hanjiu comes with specific oil compatibility parameters and maintenance instructions. Our technical team also provides one-on-one guidance to help users select the right oil for their operating conditions, thereby reducing motor wear at the source and ensuring the equipment maintains stable power output over the long term.
Standardizing daily start-up, shutdown, and operational procedures is a key maintenance practice that users most often overlook, yet one that is most effective at reducing hidden faults—and it is perfectly suited to high-frequency daily operations. Many users work at a fast pace and habitually start the machine and immediately begin operating at full load, then shut it down the moment the job is finished. This rough handling causes the internal oil pressure of the orbital motor to surge and drop suddenly, repeatedly stressing the seals, bearings, and meshing mechanisms. Over time, this leads to common issues such as seal aging, increased internal leakage, and weak acceleration. The correct procedure for daily use is very simple and easy to follow: After starting the machine each day, first let the equipment run at low speed under no load for 1 to 2 minutes. Wait until the oil circuit has fully circulated, the pressure has stabilized, and the internal components are adequately lubricated before gradually applying a load to begin work. Before shutting down at the end of the workday, first remove the load from the equipment, then let it idle at low speed for several tens of seconds to dissipate heat and stabilize the pressure before shutting it down normally. This is especially important during the cold weather of fall and winter, when the hydraulic fluid becomes viscous and less fluid. It is essential to allow time for warm-up operation to prevent stuttering and wear caused by cold starts of the motor. Hanjiu has extensive experience in real-world operating conditions and understands users’ habits of rushing to meet deadlines and frequent start-stop cycles. The company has specifically enhanced the impact resistance and fatigue resistance of its products’ designs while continuously promoting proper operating procedures to help users correct poor operating habits and significantly reduce failure rates.
In addition to the two core maintenance methods mentioned above, to align with users’ daily operating scenarios, it is also essential to perform“regular filter maintenance and daily pressure management”to establish a comprehensive maintenance system that ensures the optimal operating condition of the orbital motor. During daily operations, the oil filter serves as a critical barrier against impurities; prolonged use can cause it to clog and fail, allowing contaminants to enter the motor. Users are advised to clean or replace the filter regularly based on the intensity of their work to keep the oil circuit clean and unobstructed. At the same time, during daily operations, users must avoid prolonged pressure buildup and operating the motor under excessive loads. Prolonged overloading causes the motor to run at consistently high temperatures, accelerating component aging and serving as a major cause of premature motor failure. Proper pressure control and moderate operation can effectively maintain the motor’s peak performance. As a professional manufacturer of cycloidal hydraulic motors, Hanjiu not only provides high-quality products but also prioritizes the user’s full-cycle experience. From precision manufacturing and comprehensive pressure testing before shipment to guidance on daily use, troubleshooting, and after-sales support, Hanjiu provides comprehensive services to every customer, effectively addressing common operational challenges and helping users reduce maintenance costs while improving equipment uptime. To ensure stable and reliable operation of your orbital motor and minimize downtime caused by malfunctions, it is crucial to implement a scientific daily maintenance routine.
