What should I do if the plastic disc in the middle of the fan can t be unscrewed?

You're talking about desktop electric fans.

A large plastic cap that holds the fan blades in place, this plastic cap is reverse-filament, and is made clockwise.

The direction of turning is to remove it, and the counterclockwise direction is tighter and tighter, and it will be loosened when you turn it hard clockwise.

If you are referring to the large plastic cap that holds the fan blades, the large plastic cap is the reverse wire, that is, it is the opposite direction of the ordinary screw wire mouth, the clockwise direction is to remove, and the counterclockwise direction is to tighten more and more tightly. If you remove it in the direction of a normal screw, it will only tighten tighter and tighter.

The disc in the middle of the fan should be fixed to the fan blades, taking into account the force of rotation, it is usually an anti-wire structure, that is, it is tightened counterclockwise and loosened clockwise.

The plastic cover in the middle of the fan itself is equivalent to a tightening screw, the fan is rotated clockwise, the screw is tightened counterclockwise, and the direction of the ordinary screw is opposite, it can only be screwed down in the opposite direction, and the positive direction can only be tightened more and more.

To remove the blade first and then remove the nut in the middle, the nut in front of the blade is an anti-screw, and it should be screwed clockwise when removed.

The disc cap in the middle of the fan is reversed, that is, the direction of release is to rotate in the counterclockwise direction, you may be in the wrong direction of rotation, so you can't unscrew it.

You should have screwed it in reverse, clockwise is loose, counterclockwise is tight, and the screw is reversed.

That could be a left-handed thread, which means you have to twist it clockwise to remove it.

Summary. The plastic ring of the fan blade is the large plastic cap of the electric fan that fixes the fan blade. Turn it hard clockwise, and it will loosen and you can unscrew it.

What should I do if the small plastic dome in the fan can't be unscrewed, and the front and back screws will not move at all.

Your question has been received, it takes a little time to type, please wait a while, please don't end the consultation stool erection friend, you can also provide more effective information, so that I can better answer your <>

If the direction of rotation is not wrong, you can spray the loosening agent on the part where the nut is in contact with the shaft, and then twist it again after a while. 3.If the nut is removed by using a loosening agent, the plastic ring of the fan blade is the large plastic cap of the electric fan to fix the fan blade. Turn it hard clockwise, and it will loosen and you can unscrew it.

What should I do if the plastic disc in the middle of the fan can't be unscrewed? Hello dear, when this happens, it can be judged that the grinding energy is twisted in the wrong direction by the user, because the nut of the fan is a reverse buckle screw, and it can only be removed if it is rotated in a clockwise direction. For ordinary screws, the counterclockwise direction is disassembled; 2.

If the direction of rotation is not wrong, you can spray the loosening agent to the part where the nut is in contact with the shaft, and twist it again after a while; 3.If the nut cannot be removed by using the loosening agent, the shaft rod can be clamped with strong forceps and then disassembled with a wrench; 4.If the forceps and the adjustable wrench cannot be disassembled, the only way to destroy and disassemble is to use a heat gun to adjust the temperature to heat the nut at about 800 degrees, and then disassemble it while it is hot, which may damage the blade.

If it still can't be disassembled, it should be cooled with cold water immediately after heating, and then it can be removed by using the principle of thermal expansion and cold contraction after multiple heating and cooling. 5.If none of the above methods can be disassembled, you can use a cutting bucket cutter to cut a large part of the nut, and then use a hydraulic flarer to crack the nut, hoping to help you.

What should I do if the plastic disc in the middle of the fan can't be unscrewed? Hello dear, the models of various fans are different, and the small plastic dome inside them is also different, some are screwed, or are screwed down, or they are screwed down, and some are slapped with clips. If it is buried and can't be twisted, it ,..

To remove the blade first and then remove the nut in the middle, the nut in front of the blade is an anti-screw, and it should be screwed clockwise when removed, and after the blade is removed, the nut in the middle is a positive snail, and it should be screwed counterclockwise when removed. This may happen because the nut of the fan is a reverse buckle screw, which can only be removed if it is rotated in a clockwise direction. For ordinary screws, the counterclockwise direction is disassembled; 2.
