Correct installation of the LF60B cooling tower fan reducer requires following standardized procedures to ensure long-term stable operation of the equipment in a hot and humid environment. The following is detailed guidance based on operating procedures and maintenance points:
1. Preparation before installation
Clean the site: Make sure there are no debris in the installation area to prevent foreign objects from entering the equipment.
Check components: Check whether the installation position of each component is accurate, the fasteners are not loose, the oil circuit is smooth, and the oil level is within the specified range.
2. Key installation steps
1. Manual turning test: Turn the coupling by hand. The whole machine should run evenly and without jamming to confirm that the transmission system is well assembled.
2. Motor wiring and trial operation:
Start the motor. The impeller should rotate clockwise when viewed from above. If the direction is wrong, the motor phase sequence needs to be adjusted.
Run continuously for 1 hour without load, during which the current and vibration values are monitored, and the gear box is observed for any abnormal sounds.
3. Oil circuit and oil level management:
Use N100 medium-load industrial gear oil (GB/T5903-1995), and the oiling amount refers to the model standard (LF60 series is about 101kg).
The oil standard pipeline must be drawn out horizontally to ensure that the oil level display is accurate; after installation, you can check whether the oil level is at 20±15mm from the lower edge through the sight hole cover.
3. Sealing and probe installation
The three parameter combination probe (such as vibration, temperature, displacement) needs to be tightened and kept sealed. The contact surface can be coated with L107 silicone to prevent leakage and prevent vibration from interfering with the measurement accuracy.
4. Re-inspection after operation
The following items need to be reviewed after shutdown:
Are all connections and fasteners loose?
Whether there is oil leakage at the sealing part;
Whether the basic structure is stable to avoid displacement due to vibration.
5. Follow-up maintenance suggestions
Lubricating oil change: Change the oil for the first time after the new machine has been running for 10-15 days, and then change it every six months.
Regular overhaul: once a year, including cleaning parts, repainting, replacing worn parts (such as seals, bearings), gears need to be replaced in pairs and the meshing clearance adjusted.
Temperature measurement and monitoring: The oil temperature during operation shall not exceed 86°C. If the temperature exceeds 86°C, the machine should be shut down immediately for investigation.
