A cooling fan in use common problem

The cooling fan is mainly used to handle automobile electrical appliances, machinery, power supply of the cooling problem, falling equipment working environment temperature, in order to extend the using life of equipment. So if the cooling fan appear problem, can also lead to equipment can't work normally, and then affect the automobile production efficiency. Used to understand the cooling fan, what are the common issues can nip in the bud. Cooling fan motor is not the problem of rolling, if the centrifugal fan to present such phenomena, be sure to check the detection power supply first, then, if charged view is likely to threaten the life safety of the maintenance staff, constitute a great safety hidden trouble, in fact, many problems in the cooling fan as far as the power supply problem, it is necessary to block the power supply, to ensure safety. The noise problem in the application of the cooling fan is the most common problems. Big noise always let a person feel be agitated, so if found in the use of cooling fan noise is too big, want to look at the bolt, to see whether there is loose phenomenon. Also check the cooling fan impeller is loose, a lot of time of the cooling fan noise and blade has a direct contact, so the cooling fan once presented noise, generally think of check the cooling fan impeller part. Cooling fan bearing vibration problems, the cooling fan oscillation can cause damage of bearing and blade, bolt looseness damage, chassis and air duct, serious word will directly cause the fan will not operate properly. Cooling fan bearing vibration, overspend reason is more, according to different cause analysis should take appropriate treatment method, can have the effect of get twice the result with half the effort.
