The reason why the fan has no wind power: it has not been cleaned for too long, motor lubrication problem, the fan is too old, the direction of the Fan blades is incorrect and the fan blade is not the original machine.
1. The electric fan has not been cleaned for too long: If the electric fan has not been cleaned for too long, a large amount of dust will adhere to the surface of the fan and the air. output, causing the speed of the electric fan to weaken and the wind power of the electric fan to change slightly. In this case, you only need to clean the electric fan blades, air outlet, protective net and other parts.
2. Motor lubrication problem: The motor is not well lubricated and cannot drive the fan blades. In this case, you candisassemble the engine and try. If the shaft can still work normally, it proves that the motor is working normally, but there is not enough lubricating oil in the motor, causing the electric fan to rotate slowly and produce less air. Simply apply a little lubricating oil to the engine.
3. The fan is too old: the motor shaft sleeve is worn, causing the gap to be too large and unable to pull the load of the fan blade, causing the motor to burn easily, causing the fan to have an internal problem. engine. The resistance increases and you cannot rotate the fan blade, you should ask professional maintenance personnel to directly repair or replace the fan.
4. The fan blade direction is incorrect: the direction is reversed, this can be fixed by removing and reinstalling it.
5. Non-original fan bladesinal: Non-original fan blades have poor wind stirring capacity. If the fan blades are too small, there will be no wind. Simply replace them with original fan blades.
The reason why the electric fan has no wind is that the electric fan has not been cleaned for a long time, the motor has not not enough lubricating oil and the fan blades are installed backwards.
1. The electric fan has not been cleaned for a long time
If the electric fan has been used for too long, a large amount of dust will adhere to the blades and air outlet of the electric fan, causing interference normal fan operation. If the fan is operating normally, there may be no wind. It is necessary to disassemble the fan in time and clean the fan blades, air outlet,the protective net and other parts.
2. Insufficient motor lubricating oil
If the electric fan motor is not well lubricated, it will not be able to drive the blades. In this case, you can remove the engine. engine and try. If the shaft can still work normally, it proves that the motor is normal, but there is not enough lubricating oil in the motor, causing the electric fan to rotate slowly and produce less air.
3. The fan blades are installed upside down.
Fan blades installed upside down will not affect the electric fan. It can still turn, but there is no wind. In this case, only you. It is necessary to remove the fan blades. Reinstallation may resolve the issue.
How to use an electric fan correctly
1 Before using it for the first time every quarter, dryHeal it to avoid moisture inside and avoid electric shock. or risk of leakage. Also check if the fan and grille are installed correctly and if the plug is damaged. If damage is found, it must be repaired before use.
2. It is recommended to use a fan with an odd number of blades, and there should not be too many blades, the greater the resistance, the weaker the wind force. The odd number of blades ensures balance during rotation. Before you start using it, test it for two hours. If there is a burning smell or abnormal noise, operation should be stopped immediately and maintenance should be carried out.
3. It is recommended to start the fast speed first when using it, and then adjust it to the required speed after normal operation. This can protect the fan and save electricity.
