Common trouble shooting methods of DC cooling fan? DC COOLING FAN use time is long, or the purchase of cheap fans, quality assurance is not much, there will be some problems, then what is the general failure? 

1, suddenly noisy noise, check whether the DC cooling fan gathered too much dust, fan motor oil dry, so that the noise caused by the motor-like roar. Solution, radiator with tap water cleaning, gaps with medical small cotton swab wipe, lubricating oil dripping into the core about 1 to 2 drops can be.

 2, DC cooling fan used less than a week, noise is too large, slow speed situation may be the fan temperature is low, resulting in rotating bearings on the lubricating oil failure. Solution, to the fan into the anti-freeze lubricating oil, pay attention to the temperature of the use of the environment. 

3. The position of the DC cooling fan is shifted automatically, the fastening device of the fixed radiator is invalid, and the fan is shifted due to the resonance phenomenon caused by operation. The solution is to replace the new buckle.

The above is the Dong Xing Yue on the DC Cooling Fan Common Fault Solution? It is very important to select a good DC cooling fan, not only to make the normal operation of the equipment, but also to extend its life, increase efficiency, if you want to know more DC cooling fan knowledge can pay attention to our http://www.dxymotors.com。
