Summer is about to pass, and the electric fan is also about to enter a "hibernation" state. However, simply cutting off the power is not enough, you still need to give it a "bath". Home appliances, like people, also require "maintenance". Only by properly maintaining them can they ensure efficient operation in the coming year's use. Reasonable use of electric fans can not only maintain indoor and outdoor air circulation and achieve cooling, but also achieve dual effects of energy conservation and environmental protection. Therefore, it is also necessary to maintain the electric fan to a certain extent.
Maintenance tips for electric fans Maintenance methods for electric fans
按照风扇电路图的要求正确拆卸零件。操作时，首先打开网罩夹，松开风叶套筒上的紧固螺栓，拆下风叶，拧下固定后网罩的四个螺帽，拆下垫片和后网罩，恢复螺母垫片。正确维护喷漆零件。用软布擦拭干净。如果上面的污渍不容易去除，可以用肥皂和碱含量较少的水擦洗，或者用少量煤油擦拭，然后清洗干燥。拆卸风扇叶片后，将其包裹在软纸中，并将其放在前后网罩之间，以免风扇叶片角度变形。其他部件的维护。电源线不应与有害气体接触，例如蚊香，气体等，否则可能会变色甚至造成事故。电机轴承是含油的铜轴承。为了防止油损失，可以将适量的发动机油注入到喷油孔中。将摇头旋钮的起点置于摇头位置，以防止压缩弹簧处于非压缩状态。
Most electric fans use oil bearing, which is usually a powder metallurgy product. The oil felt tightly wrapped in the outer circle of the bearing should store a large amount of oil, which gradually seeps into the internal oil hole of the bearing for lubrication. When the electric fan is working, the motor heats up, causing friction between the shaft and the bearing to generate heat, which gradually consumes the lubricating oil. If the lubricating oil cannot be replenished as needed, the fan motor cannot maintain normal operation, resulting in a decrease in speed or even seizure, and burning the motor. Usually, during the use of electric fans, oil should be injected from the oil injection port every 1-2 months, and sewing machine oil or spindle oil can be used.
