In summer, in addition to the use of air conditioning, air conditioning, fans, we often have the possibility of using electric fans. Because for the elderly, children with low immune capacity and pregnant women, it's better not to blow air conditioning, choose to blow the fan. An electrical fan, as an electrical device, is a device that uses single-stage exchanges to achieve rotational purposes, operating on a very simple principle. But sometimes there's an electrical fan that doesn't turn. What's the reason for that
I. What's the reason for the fan not turning?
1. Poor maintenance and chronic lack of lubricants. The fan turns in part to ensure that there is lubricating oil, otherwise the wind leaves cannot be pulled. If they were at home, they could choose to turn off the power and then pull the wind leaves, and if the rotation was rigid, there was basically no lubricant。
2. The wear and tear caused by the prolonged use. If a fan lasts for a long time, the electric power will run out and the axle will burn easily。
3. Overheated fans do not turn. There's an electric device in the fan, there's an overheated circuit breaker in the engine, and if there's a short circuit around the wire, the heat will increase in a short time, so the electrics will be “struck off”。
4. Start the capacitation capacity down. When the fan is long, the capacity is reduced, which results in a smaller rectangular start-up power that cannot drive the load。
Electrical malfunctions, such as circuit damage。
Ii. How do you fix a fan if it doesn't turn?
1. Electric lubrication is not working: the priority is the failure of the lubrication of the electric power, the re-axis are refuelled, the wind leaves are not towed on it, and when removed, the re-axis are functional, which means that the power is not broken. How do you judge the lack of oil? It's just that when you cut the power, you push the wind, you find the rotation a little stiff, it means the oil is gone, and it's easy, it means the lubrication is good。
2. Over-depletion of the electric power plant: secondly, you have to consider how long the electric fans have been in use, the power opportunities have been depleted, and the axles of the electric power plant are easily burned. The prolonged use of the electric power also increases the internal resistance of the electric power and reduces its load capacity, making it impossible to rotate wind leaves。
3. Electrical overheating: the overheating of the electric power also causes a deterioration in the load capacity of the electric vehicle and the low power of the electrical power, which makes it impossible to boost the load。
4. Short circuits in the circuits: inside the electrics, it has a protective device, with a heat breaker, which is a short circuit in the circuits, leading to a sharp increase in the heat flow, a breaker, and, in the case of the electrics, a general strike. This rarely happens。
5. Reduced capacity: another is a smaller start-up capacity, which, although the parameters are written on the sign, is long enough to reduce the capacity, leading to a smaller start-up rectangular of the power, which does not boost the load. It's simple, take off the cap and replace it with a new one. The same model should be fine. But it would be better to have a 20% larger one。
6. The rotor axle is too wide: if the transformer is dismantled, the contour axle is too large to be adjusted by adjusting the gasket. When an electric generator is installed, the rotor must be co-ordinated with the bearings, the screws must be slowly hardened to the angles, and then the wheel will be knocked on with the headwood, making it converge. It's simple to decipher the power, but it's not easy to reload it, so don't let it happen, otherwise it's just bad。
In the case of the failure of electrical fans, it may be due to poor routine maintenance, either because of the length of time spent, or because of the excessive heat associated with the continuous operation of electrical fans, etc. For specific reasons, details are given above, and for specific reasons, detailed solutions are given, so that you can treat the symptoms and find the root causes of the problem. Of course, when repairing, do not forget to cut the power in case of unnecessary trouble or even danger。
