1. Why does the explosion-proof and anti-corrosion fan bearing seat leak oil? How to check and deal with the oil leakage of the explosion-proof and anti-corrosion fan bearing seat?
Answer: There are usually the following phenomena that cause oil leakage of explosion-proof and anti-corrosion fans. The detection and handling methods for the following problems are as follows:
1. Check whether the oil is added too much.
2. Deal with reducing the oil volume, open the perforated cover, open the oil drain valve, and reduce the bottom oil volume to the center of the red dot, not exceeding the lower position and the center of the red dot.
3. Check whether the oil type is correct.
4. Deal with and replace the oil. Drain all the original oil, then clean the bearing seat, and then add oil that meets the standard to the standard position.
5. Check whether the explosion-proof and anti-corrosion fan is installed horizontally.
6. Under the relative base of the explosion-proof and anti-corrosion fan, adjust the level of the explosion-proof and anti-corrosion fan with steel plate or PP plate, and adjust the rack of the explosion-proof and anti-corrosion fan to the level of the explosion-proof and anti-corrosion fan.
7. Check whether the pile line of the end cover of the bearing seat is loose or damaged.
8. Dispose of the locked pile and replace the anti-corrosion pile.
9. Check whether the V-ring and O-ring are installed on the explosion-proof and anti-corrosion fan, and whether they are damaged.
10. The handling and replacement of V-rings and O-rings should comply with the bearing replacement standard manual.
11. Check whether the oil return hole of the bearing seat cover is blocked or enlarged.
12. Transport, open the bearing seat cover, clean foreign matter, clean the cover, expand the oil return hole, and reassemble.
13. Check whether the oil observation window and the oil drain valve are locked and scratched.
14. Add material tape to the oil sight glass and oil drain valve, replace the oil sight glass and oil drain valve, and replace the bearing seat.
15. Check whether the bearing seat of the anti-corrosion air ladder is damaged and whether there are blisters.
16. Processing multi-magnetic bearings or welding cracks with electric welders.
2. How does the vibration of the explosion-proof and anti-corrosion fan occur? What are the phenomena of explosion-proof and anti-corrosion fan vibration?
Answer: The common vibrations of explosion-proof and anti-corrosion fans are as follows: check whether there are too many crystals in the impeller of explosion-proof and anti-corrosion fans; treat and clean the crystals on the impeller; check whether the impeller of explosion-proof and anti-corrosion fans is deformed and whether the blades are bent: deal with and replace the impeller of explosion-proof and anti-corrosion fans. : According to the impeller installation standard; check whether the impeller is out of balance: deal with the dynamic balance according to the dynamic balance operation standard; check whether the anticorrosive air ladder bearing is damaged: if there is abnormal noise, replace the bearing according to the operation standard.
