Explosion proof motors are usually used in flammable and explosive hazardous areas, including explosive gas environments, combustible dust environments, and fire hazard environments. Explosion proof motors are often in continuous operation, with harsh working conditions and multiple sudden factors, resulting in a high probability of motor failure, posing a huge threat to production and personnel. So strengthening the maintenance and management of explosion-proof motors is of great significance for preventing or reducing explosion-proof motor failures and ensuring production. Below, let's follow Nanyang explosion-proof motor to see how to maintain explosion-proof motors.

1. Strengthen the daily maintenance of explosion-proof motors

The daily maintenance of the motor mainly aims to create a good environment for the healthy operation of the motor, avoid rust marks and spots on the explosion-proof surface of the motor, ensure tight contact between the contact surfaces, and prevent harmful media from entering and corroding the internal parts and winding insulation. Therefore, it is necessary to do the following work well: first, maintain a clean and dry working environment for the motor. The second is moisture-proof and waterproof. For explosion-proof motors operating in humid environments, avoiding the accumulation of water inside the motor and maintaining the dryness and insulation stability of the motor coil are prerequisites to ensure the operation of the motor. The moisture-proof and waterproof effect of explosion-proof motors mainly depends on the protective work done by the motor casing, which can prevent the surface moisture of the motor from entering the machine. The third is to keep the surface of the motor clean and ensure that the air inlet is not obstructed by dust. The fourth is to ensure good lubrication of the motor during operation. Once the bearings are found to be overheated or the lubrication deteriorates during operation, the lubricating oil should be replaced in a timely manner.

2. Establish a sound maintenance system

Establish technical files for explosion-proof motors, record the historical and current operating conditions of each motor, in order to provide data for dynamic monitoring of the motor. In the daily operation process of the motor, a daily inspection and inspection system should be established and followed, and problems should be discovered and dealt with in a timely manner to eliminate hidden dangers. Develop annual, quarterly, and monthly maintenance plans for motors to achieve pre inspection and repair.

3. Develop and adhere to scientific and technical norms

Explosion proof motors operate in hazardous environments and belong to special production equipment. Scientific technical specifications are established for their daily maintenance and repair, and illegal operations are strictly prohibited. Therefore, it is prohibited to disassemble the motor arbitrarily during daily maintenance; During disassembly and maintenance, it is not allowed to damage the explosion-proof surface. During maintenance, technical specifications should be strictly followed, such as using special tools during disassembly, ensuring that the explosion-proof surface is facing upwards and covered with protective pads; When installing, special tools should be used and the connecting screws should be tightened to reduce the fit gap and maintain good explosion-proof performance. It is prohibited to arbitrarily change the specifications and models of wiring cables, as well as the sealing rings of wiring cables and ports.

4. Choose a suitable explosion-proof motor

In addition to the above precautions, selecting the appropriate explosion-proof grade explosion-proof motor correctly is a prerequisite. Purchasing a brand explosion-proof motor from legitimate channels will provide more guarantee, product quality is guaranteed, and pre-sales and after-sales service support is more in place.

I hope this sharing of Nanyang explosion-proof motors will be helpful to you. Thank you for watching.
