High temperature in the circulation fan bearing with what method to deal with?
2021 -
02 -
11 the main cause of bearing temperature on the high side has the following points: (
1)
Lubrication is not good in quality.
The purpose of lubrication, is to make the action part does not directly contact friction, and form of the friction between solid and liquid.
If the number of lubricating oil shortage or poor quality, can make the part of dynamic and static friction heat directly, or heat by oil away, can't and make the bearing temperature rise.
(
2)
Turn the bad bearing assembly quality.
Such as the inner sleeve and shaft tight force is not enough, coat and bearing clearance is too large or too small.
(
3)
Bearing quality is bad.
Sliding bearing grind quality bad, sharply bad contact or changed;
Decent and turning bearing crack, fracture, peeling, etc. , can destroy the stability of oil film with uniformity and bearing heating surface.
(
4)
Sealing felt tight and fever.
(
5)
Bearing vibration under impact load, the serious influence the stability of oil film.
(
6)
Bearing cooling water shortage or disruption, affect the heat out of, and make the bearing temperature rise.
The above answers are for reference only.
