Explosion-proof motors are widely used in flammable and explosive dangerous places, including explosive gas environment, combustible dust environment and fire hazard environment, etc., mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, it is also widely used in textile, metallurgy, urban gas, transportation, grain and oil processing, papermaking, medicine and other departments. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery. Explosion-proof motors are often in continuous working state, the working conditions are harsh, there are many unexpected factors, and the probability of motor failure is relatively high, which poses a huge threat to production and personnel. Therefore, strengthening the maintenance and management of explosion-proof motors is of great significance for preventing or reducing explosion-proof motor failures and ensuring production.
Strengthen the daily maintenance of explosion-proof motors
The daily maintenance of the motor is mainly to create a good environment for the healthy work of the motor, to avoid rust and rust spots on the explosion-proof surface of the motor, to ensure that the contact surface is in tight contact, to prevent harmful media from entering the machine, and to corrode the internal parts and winding insulation. . Therefore, the following work needs to be done:
One is to keep the working environment of the motor clean and dry.
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 stability of the motor coil and insulation are prerequisites to ensure the operation of the motor. The moisture-proof and waterproof effect of the explosion-proof motor mainly depends on the protection work done by the motor shell, which can prevent the water on the surface of the motor from invading the machine.
The third is to keep the surface of the motor clean to ensure that the air inlet should not be obstructed by dust.
The fourth is to ensure good lubrication of the motor during operation. Once the bearing is found to be overheated or the lubrication is deteriorated during operation, the lubricating oil should be replaced in time.
Establish a perfect maintenance system
Establish technical files of explosion-proof motors, record the historical and current operating conditions of each motor, so as to provide data for dynamic monitoring of motors. During the daily operation of the motor, a daily inspection and inspection system should be formulated and followed, problems should be discovered in time, handled in time, and hidden dangers should be eliminated in time. Formulate annual, quarterly and monthly maintenance plans for motors, so as to achieve pre-inspection and pre-repair of motors, and eliminate faults in the bud.
Develop and comply with scientific and technical specifications
Explosion-proof motors work in dangerous environments and belong to special production equipment. Scientific technical specifications are formulated for their daily maintenance and repairs, and illegal operations are strictly prohibited. For this reason, it is forbidden to disassemble the motor at will in the routine maintenance process; during disassembly and maintenance, it is not allowed to damage the explosion-proof surface. During maintenance, the technical specifications should be strictly followed. For example, special tools should be used when disassembling, to ensure that the explosion-proof surface is placed on top and covered with protective lining; explosion-proof performance. It is forbidden to arbitrarily change the specification and model of the wiring cable, as well as the wiring cable and the sealing ring of the wiring port.
