Mine motor manufacturer Several precautions for daily maintenance of explosion-proof motors
Mine motor manufacturer: What precautions should be taken for the daily maintenance of explosion-proof motors?
Explosion-proof motors are widely used in flammable and explosive hazardous locations, such as explosive gas environments, combustible dust environments, and fire hazard environments. Explosion-proof motors are often in continuous operation, with harsh working conditions, many unexpected factors, and a high probability of motor failure, posing a huge threat to safe production and personnel safety. Therefore, strengthening the maintenance and management of explosion-proof motors is of great significance in preventing or reducing explosion-proof motor failures and ensuring safe production.
Mine motor manufacturer: 1. Strengthen the daily maintenance of explosion-proof motors
The daily maintenance of motors is mainly to create a good environment for the healthy operation of the motor, avoid rust and rust spots on the explosion-proof surface of the motor, ensure that the contact surfaces are tightly contacted, prevent harmful media from entering, and corrode the internal parts and windings of the motor. Therefore, the following work needs to be done: First, keep the motor's working environment clean and dry; second, prevent moisture and water. For explosion-proof motors operating in humid environments, avoid water accumulation inside the motor and keep the motor windings dry and the insulation stable, which is a prerequisite for ensuring the safe operation of the motor. The moisture and water resistance of the explosion-proof motor mainly depends on the protection work done on the motor casing, which can prevent surface moisture from entering the machine; third, keep the motor surface clean and ensure that the air intake is not blocked by dust; fourth, ensure good lubrication during motor operation. If the bearings overheat or deteriorate during operation, the lubricating oil should be replaced in time.
Mine motor manufacturer : 2. Establish a sound maintenance system
Establish technical files for explosion-proof motors, recording the history and current operating status of each motor to provide data for dynamic monitoring of the motor. During the daily operation of the motor, a daily inspection system should be formulated and followed to facilitate the timely discovery and handling of problems and the timely elimination of safety hazards. Formulate annual, quarterly, and monthly maintenance plans for the motor to achieve pre-inspection and pre-repair, eliminating faults in their infancy.
Mine motor manufacturer: 3. Formulate and abide by scientific technical specifications
Explosion-proof motors operate in hazardous environments and are special production equipment. Daily maintenance and repair must be carried out in accordance with scientific technical specifications, and unauthorized operations are strictly prohibited. Therefore, during daily maintenance, it is forbidden to disassemble the motor at will; during inspection and repair, the explosion-proof surface must not be damaged; during repair, the technical specifications must be strictly followed, such as using special tools during disassembly to ensure that the explosion-proof surface is in place and covered with a protective pad; during installation, special tools must be used, and the connecting screws must be tightened to reduce the mating clearance and maintain good explosion-proof performance. It is strictly forbidden to arbitrarily change the specifications and models of the connecting cables, the sealing rings of the connecting cables and connecting ports, etc.
Mine motor manufacturer : 4. Select suitable explosion-proof motors
In addition to the above precautions, the correct selection of explosion-proof motors with suitable explosion-proof grades is a prerequisite for everything. Purchasing brand explosion-proof motors from formal channels will be more secure, with guaranteed product quality and better pre-sales and after-sales service support.
If you need to purchase explosion-proof motors or mine motors, please contact our manufacturer.
