Explosion proof motors are a special type of electrical equipment mainly used in flammable and explosive working environments. To ensure the safety of personnel and the normal operation of equipment, it is necessary to comply with a series of regulations when using explosion-proof motors. Below, Nanyang explosion-proof motor will take you to have a detailed understanding:

Firstly, a comprehensive inspection and testing of the equipment is required before using explosion-proof motors. Check whether the equipment meets explosion-proof requirements, such as whether the shell is tight and whether the protection level meets the requirements. The function of the testing equipment is normal, safe and reliable, ensuring that the equipment can withstand the special conditions of the environment in which it is located.

In workplaces using explosion-proof motors, it is necessary to classify and evaluate the location to determine whether it is a flammable and explosive area. According to relevant national standards, flammable and explosive areas are divided into different regional levels, and appropriate explosion-proof motor models and characteristics are selected based on the regional level.

When using explosion-proof motors in flammable and explosive areas, they must be installed, connected, and maintained in accordance with national standards and regulations. Before installation, it is necessary to evaluate the site to determine whether there is a special environment such as fire mist and combustible dust. Select appropriate sealing methods, anti-corrosion measures, and wiring methods according to environmental requirements.

The power supply system of explosion-proof motors also needs to meet certain requirements. For example, explosion-proof cables should be used for power supply, explosion-proof junction boxes should be used for wiring, and explosion-proof lamps should be used for lighting. The power supply system should also take comprehensive protective measures to prevent overload, short circuit, and leakage.

When using explosion-proof motors, operators must undergo specialized training and qualification certification. Operators should be familiar with the performance characteristics, operating methods, and safety precautions of explosion-proof motors. Understand the operating procedures for starting, stopping, regulating speed, and handling abnormalities of equipment, as well as how to respond to unexpected situations and accidents.

In daily use, it is necessary to regularly inspect and maintain explosion-proof motors to ensure the normal operation and safe use of the equipment. Regularly inspect the appearance and sealing performance of the equipment to maintain cleanliness. Check the insulation performance and grounding of the motor, as well as the wear of the motor blades, bearings, and shaft seals. Timely replace and repair aged, worn, and malfunctioning components.

During the use of explosion-proof motors, attention should be paid to the control of motor temperature and power. The working temperature of explosion-proof motors is usually lower than that of standard motors, and it is necessary to control the temperature reasonably to avoid overheating causing faults. The control of power should be adjusted according to the load and working conditions of the equipment to avoid overloading the motor.

When using explosion-proof motors, safety operating procedures should be followed, and unauthorized opening of the motor casing, replacement of components, and modification of circuits are strictly prohibited. For any abnormal situations of the equipment, such as noise, vibration, overheating, etc., immediate shutdown and maintenance should be carried out to prevent accidents from occurring.

Nanyang explosion-proof motor tells you that when using explosion-proof motors, it is necessary to strictly follow national standards and specifications for operation and maintenance. Only by ensuring the normal operation and safe use of equipment can accidents and hazards in flammable and explosive environments be effectively prevented and controlled.
