How to maintain DMS50 Modular Design Hydraulic Motor on a daily basis

The modular design of the DMS50 modular hydraulic motor improves the flexibility and maintainability of the equipment, but also brings some unique maintenance challenges. Modularity means that the connections and seals between the various components are more complex, and more sophisticated maintenance operations are required to ensure the tight fit and sealing between the modules. Daily maintenance is the key to preventing equipment failures, extending service life, and maintaining efficient operation. For the DMS50 modular hydraulic motor, daily maintenance includes not only inspection and replacement of worn parts, but also cleaning, lubrication, tightening and adjustment. Through regular daily maintenance, problems can be discovered and solved in a timely manner, and small problems can be prevented from turning into major failures, affecting the overall performance and operational safety of the equipment.

1. Daily maintenance steps and key points
Check for oil leakage: Regularly observe whether there is oil leakage on the surface and around the hydraulic motor. If there is oil leakage, the cause should be found and repaired in time to prevent oil loss and environmental pollution.
Check the connectors: Check whether the connecting bolts and pipe joints between the modules are loose or damaged. If they are loose, they should be tightened in time. If they are damaged, they should be replaced with new ones.
Check the appearance damage: Check whether the hydraulic motor housing has cracks, deformation, corrosion, etc. If there is any damage, assess its severity and repair or replace it if necessary.
Regular cleaning: Wipe the surface of the hydraulic motor with a clean cloth or special cleaning agent to remove oil and dust. Be careful to avoid using highly corrosive cleaning agents to avoid damaging the surface of the equipment.
Maintain ventilation: Ensure that there is enough ventilation space around the hydraulic motor to avoid overheating and dust accumulation.
Check the filter: Regularly check and clean the filter in the hydraulic system to prevent impurities from entering the hydraulic motor and affecting its normal operation.
Check lubrication: Check whether the internal lubrication system of the hydraulic motor is unobstructed and whether the lubricating oil is sufficient and clean. If the lubricating oil is insufficient or seriously contaminated, it should be replenished or replaced in time. Check the seals
: Check whether each seal is aging, worn, or damaged. If damaged, it should be replaced in time to ensure good sealing performance. Performance
Test: Regularly perform performance tests on the hydraulic motor, including parameters such as speed, torque, and pressure. Through performance tests, the performance status of the hydraulic motor can be evaluated, and problems can be discovered and solved in time.
Adjust parameters: According to the performance test results and actual needs, adjust the relevant parameters of the hydraulic motor (such as flow, pressure, etc.) to ensure that it operates in the best condition.

2. Special maintenance and precautions
Shutdown maintenance: During the equipment shutdown period, make full use of this time for in-depth maintenance and inspection, including disassembly and cleaning, replacement of wear parts, etc.
Professional training: Provide professional training for operators and maintenance personnel to let them understand the structure, performance and maintenance methods of the DMS50 modular design hydraulic motor, improve maintenance level and work efficiency.
Emergency preparation: Develop emergency plans and troubleshooting procedures to ensure that you can respond quickly and take effective measures when equipment fails.
