What should be done to prevent abnormal temperature in the high temperature of the fan

1. It may be due to the high temperature rise of the bearing of the high-pressure fan:

About this part of the content, we can think through four aspects, one may be due to high temperature and high pressure caused by the heat fan bearing box cover and seat connecting bolt tight force is too large or too small; Second, because the bearing box presents a relatively violent vibration problem; Three, the rolling bearing of the fan is damaged; Four is due to the lack of smooth, or it contains more impurities.

2. May be due to high temperature and high pressure fan motor current is too large:

When it is working, in order to ensure that it is in normal working state, we need to provide it with normal power supply voltage, but there are also some factors that will cause its motor current to increase. For example, because of the influence of the violent vibration by the bearing box, or in the open air blower, the inlet and vent pipe gate is not closed in time, or the spindle speed is too large, more than the rules of value, or diagonal flow fan motor input voltage is too low, or the motor single power, etc., these problems will form the motor current is added, Thus the problem of equipment temperature rise is formed.
