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
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.
