1, Why does the bearing seat of anti-corrosion fan leak oil? How to check and deal with the oil leakage of bearing pedestal of anti-corrosion fan?
Answer: the oil leakage of anti-corrosion fan is generally caused by the following phenomena. The following problems are presented. The detection and treatment methods are as follows:
1.Check whether the oil increase is excessive
2. Handle the falling oil volume, open the perforated cover, open the oil drain valve, and the bottom oil volume to the center of the red dot shall not exceed the orientation between the lower and the center of the red dot
3. Check whether the oil type is correct
4. Treat and replace the engine oil, drain all the original engine oil, clean the bearing seat, and then increase the engine oil that meets the standard to the standard direction
5. Check whether the anti-corrosion fan device is horizontal
6. Treatment: adjust the level of anti-corrosion fan with steel plate or PP plate under the relative base of anti-corrosion fan, and adjust the tooth strip of anti-corrosion fan until the anti-corrosion fan stops horizontally
7. Check whether the wire stack on the end cover of the bearing seat is loose and whether it is corroded
8. Handle the locking wire stack and replace the anti-corrosion wire stack
9. Check whether the anti-corrosion fan is equipped with V-ring and O-ring and whether they are damaged
10. Handle and replace v-rings and O-rings according to the operation standard for bearing replacement
11. Check whether the oil return hole of bearing pedestal cover plate is blocked and expanded
12. Handle, open the bearing seat cover plate, clean the foreign matters, clean the cover plate, expand the oil return hole and reassemble it
13. Check whether the oil sight glass and oil drain valve are locked and scratched
14. Handle oil sight glass and oil drain valve, add raw material belt, replace oil sight glass and oil drain valve, and replace bearing seat
15. Check whether the bearing seat of anti-corrosion air ladder is broken and whether there are sand holes
16. Deal with the cracks welded by the bearing seat or electric welding machine
2, How does the vibration of anti-corrosion fan occur? What are the phenomena of anti-corrosion fan vibration?
Answer: the common vibration of anti-corrosion fan is generally the following phenomena and treatment methods: check whether there are too many crystals on the impeller of anti-corrosion fan: treat and clean the crystals on the impeller; Check whether the impeller of anti-corrosion fan is deformed and whether the blade is tortuous: treat and replace the impeller of anti-corrosion fan. Replacement method: according to the standard book of impeller device; Check whether the impeller is out of balance: handle the on-site dynamic balance according to the dynamic balance operation standard; Check whether the bearing of the anti-corrosion air ladder is damaged: if there is abnormal noise, handle and replace the bearing according to the operation standard.
