For water-cooled motors, the first step in daily operation is to inspect the cooling system. Regularly monitor the cooling water temperature, flow rate, and pressure to ensure they remain within normal ranges, while also checking water pipes, connections, and seals for leaks or looseness. If a significant drop in water flow or an abnormal rise in cooling water temperature is detected, shut down the motor immediately for inspection to prevent overheating caused by inadequate heat dissipation.
The motor itself also requires regular inspection, with a focus on operating noise, vibration, and temperature rise. Under normal conditions, the motor should run smoothly; any abnormal noise, noticeable vibration, or sudden temperature spikes warrant an immediate investigation into the cause. Bearings are prone to wear and require inspection and maintenance based on the motor's design and usage requirements; address severe wear promptly to avoid disrupting the rotor's normal operation.
Cooling water quality is another critical factor. Prolonged use of cooling water containing excessive impurities or corrosive substances can lead to internal scaling, blockages, or even corrosion, thereby impairing heat dissipation. Therefore, select the appropriate coolant according to equipment specifications and regularly replace the fluid or clean the cooling system based on actual usage. For equipment that operates continuously, periodically check for internal sediment buildup to ensure the cooling circulation remains effective.
Regularly inspect the motor's wiring, cables, and external mounting to ensure connections are secure and cables show no signs of damage or aging. When restarting equipment after a prolonged shutdown, conduct a comprehensive inspection of the cooling circuits, electrical wiring, and mechanical components to verify everything is in order before startup. Diligent daily maintenance not only reduces operational faults in water-cooled motors but also helps extend their service life.
