Explosion proof motor is a type of motor with explosion-proof function, widely used in hazardous locations in industries such as chemical, petroleum, and metallurgy. To ensure the normal operation and extend the service life of explosion-proof motors, maintenance and upkeep are very important. Below, we will introduce some common maintenance methods and precautions for explosion-proof motors in Nanyang.

1、 Maintenance methods

1. Regular inspections

Regularly inspect the casing of the explosion-proof motor to ensure that it is free from damage and cracks. At the same time, it is necessary to inspect the explosion-proof signs of the motor to ensure that they are clear and visible, without any signs of wear or fading.

Check if the cable connection of the motor is firm and if there is any detachment or looseness. Check the cooling system of the motor to ensure that the cooling fan is free from blockages or foreign objects.

Regularly inspect the bearings of the motor to ensure that there is no abnormal noise or overheating. At the same time, pay attention to whether the bearings need to be lubricated or replaced.

2. Clean the motor

Regularly clean the surface and interior of the motor. The dust and dirt on the surface of the motor can affect heat dissipation and cause the motor to overheat. You can use a clean cloth to wipe the outer surface of the motor, being careful not to use chemical solvents or corrosive substances.

When cleaning the inside of the motor, first cut off the power and ensure that the motor cools before starting cleaning. You can use a vacuum cleaner or compressed air to clean the dust and debris inside the motor. Be careful not to damage the internal parts and cables of the motor during cleaning.

3. Check insulation

Regularly inspect the insulation performance of explosion-proof motors. Measure the insulation resistance of the motor using an insulation testing instrument to ensure it is within the normal range. If the insulation resistance value is lower than the specified value, it indicates that there is a problem with the insulation performance of the motor, and timely repair measures need to be taken.

4. Lubricating bearings

Bearings are very important components in motors and require regular lubrication. Choose appropriate lubricating oil for lubrication based on the duration of motor use and working environment.

Before adding lubricating oil to the bearings, clean the surface of the bearings of dust and dirt. Then select appropriate lubricating oil according to the type and specifications of the bearing for addition. Be careful not to add too much lubricating oil to prevent it from overflowing.

2、 Precautions

1. Safe use

Explosion proof motors are used in hazardous areas and must be operated strictly in accordance with the operating procedures. Avoid using motors that do not meet explosion-proof requirements in flammable and explosive environments. At the same time, it is necessary to regularly check the explosion-proof performance of the motor to ensure its normal operation.

2. Prevent overload

The rated power of explosion-proof motors is determined based on their design and manufacturing characteristics, and cannot exceed the rated power for use. Be careful not to run under overload for a long time during use to avoid affecting the service life of the motor.

3. Prevent overheating

Explosion proof motors generate heat during operation, so attention should be paid to heat dissipation. Maintain air circulation around the motor and do not block the cooling fan of the motor.

4. Pay attention to protection

Explosion proof motors are usually installed in hazardous areas and are susceptible to external damage. Therefore, effective protective measures should be taken for the motor during installation and use to prevent it from being hit or squeezed by objects.

5. Routine maintenance

Regular maintenance and upkeep of explosion-proof motors are important measures to ensure their normal operation. Develop corresponding maintenance plans based on the usage time and working environment of the motor. Regularly clean the motor, check if all components of the motor are functioning properly, and promptly repair or replace any faulty components.

Nanyang explosion-proof motor tells you that maintenance is an important means to ensure the normal operation and extend the service life of explosion-proof motors. Regular inspections, cleaning, insulation testing, lubrication, and adherence to precautions can effectively prevent motor malfunctions and damage. When using explosion-proof motors, safety regulations should be followed and protective measures should be taken to ensure the safety of the working area.
