The manufacturer of Nanyang explosion-proof motors stated that electrical equipment will inevitably be repaired and maintained after being used for a long time to ensure better operation of the equipment. There are also some points to pay attention to during the repair process. This time, we mainly introduce the marking settings for electrical equipment after repair.

Generally, new components are purchased from the manufacturer, and the repair unit should ensure that the spare parts used are compatible with the explosion-proof electrical equipment being repaired. If spare parts related to equipment characteristics are assumed by the manufacturer, equipment specifications, or relevant explosion-proof certification documents, and the rules assume that they cannot be supplied by the original manufacturer, and there are available and complete component technical conditions, and the quality policy of the repair unit allows, then the repair unit can produce replacement parts. However, records of these replacements should be kept and provided to the customer.

Explosion proof electrical equipment assumes that replacement bolts should use bolts of the same type, diameter, pitch, and length, with tensile strength consistent with the original equipment regulations. The gasket, flat washer, or locking pin under the bolt head, screw head, and nut should not be replaced, except when there are rules in the original explosion-proof certificate documents or explosion-proof type special specifications. Signs should be set on the equipment to distinguish between repair or maintenance and repair units.

The manufacturer of Nanyang explosion-proof motors stated that explosion-proof electrical signs can be added to individual signs. It is necessary to modify or remove the original signboard or add a signboard in the following situations:

1. Assuming that the electrical equipment has been modified during repair, maintenance, or modification, and still complies with this part and explosion-proof specifications, but may not necessarily comply with the rules of explosion-proof certificate documents, the original explosion-proof certificate signboard should be preserved, and the repair mark "R" should be written in an inverted triangle.

2. Assuming that after equipment repair, maintenance, or modification, the modified equipment no longer complies with the regulations and explosion-proof certification rules, the explosion-proof certification mark and "Ex" mark should be removed to obtain compensation for explosion-proof

3. Assuming that for equipment that has obtained an explosion-proof certificate in the early years and does not know the specifications based on which the equipment is manufactured, it should be

According to the latest version of this section and relevant explosion-proof regulations, before returning the equipment to the factory, the repair unit should conduct a judgment on the repaired equipment to verify whether it meets the corresponding safety level. The judgment is that the operation should be carried out by qualified personnel who determine the explosion-proof equipment.
