How to repair various parts of air compressor motor?

The air compressor motor is the key device for the operation of the air compressor. The motor drives the host through the transmission link to generate compressed air. The following will introduce some possible problems and repair methods of air compressor parts.

1. Junction box

If the terminals in the junction box are damaged, they should be replaced with spare parts that are the same as the original parts to ensure requirements such as different potentials, electrical gaps between parts, creepage distances, and wiring fastening methods.

2. Motor fan

If the outer fan or fan cover of the motor is damaged, it should be noted that the distance between the fan and the fan cover, baffle and fasteners is not less than 1% of the fan diameter and at least 1 mm to avoid friction and collision sparks. If you replace the external fan, the magnesium content of the aluminum alloy fan should not exceed 6%. If you replace the external fan with a plastic fan, you should use explosion-proof tested accessories. When repairing or replacing the fan cover, its protection level should meet the requirements of explosion-proof standards.

3. Explosion-proof shell

The casing of the motor is a protective casing, which can be repaired using the same techniques used to repair casings of general electrical products to restore its original casing protection level. Make partial modifications to the explosion-proof enclosure, such as adding terminal blocks, adding introduction devices, etc. However, such modifications must comply with relevant regulations.

4. Cables and conduits

The elastic sealing ring introduced into the device should be replaced with a spare part of the same size and quality. After the flameproof motor introduction device is repaired, the original equipment introduction method must not be changed, and must comply with relevant regulations.

The above is how to repair some parts of the air compressor motor. If there are other problems with the air compressor motor or it cannot be repaired by yourself, it is recommended to consult a professional before repairing it.
