The daily operating status monitoring of NGW-L-F61 cooling tower planetary reducer mainly includes five aspects: vibration monitoring, temperature monitoring, lubrication status inspection, sealing evaluation and operating sound observation. Among them, vibration and temperature are the core monitoring indicators, which directly reflect the health status of the equipment.
1. Vibration monitoring
Standard requirements : During normal operation, the vibration amplitude of the shell should be ≤0.08mm. Exceeding this value should cause alertness.
Detection method : During daily inspections, use hand feel or a portable vibration meter to detect the bearing seat, focusing on observing horizontal and vertical vibrations.
Abnormality Judgment : If periodic jitter or impact vibration occurs, it may be caused by uneven gear meshing, shaft misalignment or planetary gear assembly deviation.
2. Temperature monitoring
Temperature control standard : The shell temperature during operation should be ≤80°C, and the temperature rise rate should be controlled at ≤2°C/hour; if the temperature exceeds 90°C or rises sharply in a short period of time, the machine must be shut down immediately for investigation.
Monitoring suggestions : Install temperature measuring probes on the input shaft, output shaft and planet carrier bearings to achieve continuous temperature monitoring and prevent overheating due to poor lubrication or abnormal load.
3. Lubrication status inspection
Oil level confirmation : Regularly check whether the lubricating oil level is at the center line of the sight window to avoid running without oil.
Oil quality assessment : Observe whether the lubricating oil is turbid, emulsified or contains metal particles. If necessary, conduct oil sample analysis to determine internal wear.
Oil change cycle : According to the operating environment and manufacturer's recommendations, it is usually replaced every 6 to 12 months. The cycle should be shortened under high load conditions.
4. Sealing evaluation
Leakage inspection : Check the output shaft, input shaft and box joint surface daily for oil leakage or oil dripping.
Oil seal status : Aging and eccentric wear of the seal will cause lubricating oil leakage, which in turn will cause dry wear of the bearing and needs to be replaced in time.
Protection requirements : Ensure that the breathing valve is unobstructed to prevent seal failure due to internal pressure increase.
