Maintenance Techniques and Methods for Electric Fans
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
Disassemble the parts correctly according to the requirements of the fan circuit drawing. When operating, first open the mesh cover clamp, loosen the fastening bolts on the fan blade sleeve, remove the fan blade, unscrew the four screw caps that fix the rear mesh cover, remove the gasket and rear mesh cover, and restore the nut gasket. Maintain the painted parts properly. Wipe clean with a soft cloth. If the stains on it are not easy to remove, you can use soap and water with less alkali content to scrub, or use a small amount of kerosene to wipe, then clean and dry. After disassembling the fan blade, wrap it in soft paper and place it between the front and rear mesh covers to avoid deformation of the fan blade angle. Maintenance of other parts. The power cord should not come into contact with harmful gases, such as mosquito repellent incense, gas, etc., otherwise it may change color or even cause accidents. The motor bearing is an oil containing copper bearing. To prevent oil loss, an appropriate amount of engine oil can be injected into the oil injection hole. Place the beginning of the shake head knob in the shake head position to prevent the compression spring from being in a non compressed state.
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.
