Explosion proof motor is a type of motor used in hazardous environments, which has explosion-proof performance and can effectively prevent the risk of fire or explosion caused by the motor. When installing and maintaining explosion-proof motors, Nanyang explosion-proof motors tell you the following precautions to pay attention to.

1、 Preparation before installation

1. Thoroughly understand the working environment: Understand the fire and explosion hazards of the working environment, including the types and concentrations of hazardous gases.

2. Safety protection measures: Determine corresponding safety protection measures based on the characteristics of the working environment, such as selecting appropriate explosion-proof levels and conducting site cleaning.

2、 Equipment selection and inspection

1. Compliance with regulatory requirements: Ensure that the selected explosion-proof motor meets relevant international and national regulatory requirements, such as national electrical codes, international standards IEC, etc.

2. Check the integrity of the equipment: Check whether the appearance of the explosion-proof motor is intact, whether there are deformations, cracks, defects, etc.

3. Detection of explosion-proof performance: Conduct corresponding experiments and tests to verify whether the explosion-proof motor has the specified explosion-proof performance, such as using a current limiter to determine whether the explosion-proof motor shell can withstand arc and explosion pressure.

3、 Installation and connection

1.Installation location selection: Based on the usage requirements of explosion-proof motors, choose the installation location reasonably to avoid the accumulation of flammable and explosive substances and factors affecting safe operation.

2. Electrical connection: Use cables, plugs, and sockets that meet the requirements to ensure that the electrical connection is firm and reliable, and strictly follow the electrical wiring diagram for wiring.

4、 Maintenance and upkeep

1. Regular inspection: Regularly inspect the appearance, electrical connection, bearing condition, etc. of explosion-proof motors to ensure their normal operation and safety.

2. Cleaning and anti-corrosion protection: Regularly clean the shell, blades, air ducts, and other parts of explosion-proof motors to prevent dust accumulation and corrosion.

3. Lubrication and maintenance: Regularly lubricate and maintain the bearings and transmission devices of explosion-proof motors to ensure their normal operation and extended service life.

4. Spare parts: Prepare commonly used vulnerable parts and key components of explosion-proof motors for replacement and maintenance in case of emergencies.

5、 Safe operation

1. Employee training: Provide training to employees who use and maintain explosion-proof motors to understand the characteristics, usage methods, and safety operating procedures of explosion-proof motors.

2. Prohibit unauthorized connection: Employees are prohibited from changing the electrical connection method of explosion-proof motors without permission, and are strictly prohibited from connecting cables or changing circuits without permission.

3. Normal operation: Explosion proof motors can only operate normally under specified working conditions and cannot exceed their rated voltage, rated current, and other operating parameters.

Nanyang explosion-proof motor tells you that the installation and maintenance of explosion-proof motors need to strictly follow relevant specifications and requirements to ensure their stable operation in hazardous environments and prevent the occurrence of dangerous events such as fires and explosions. At the same time, strengthening the safety awareness and training of employees, improving the professional quality and safety awareness of operators, is also an important link to ensure the safe operation of explosion-proof motors.
