Explosion proof motor is a type of motor designed for special environments, which can work in flammable and explosive places and has the characteristic of preventing sparks from generating. Explosion proof motors are mainly widely used in flammable and explosive places such as petrochemicals, dust environments, coal mines, and liquids. Therefore, special attention should be paid to safety precautions when using them. Below, Nanyang explosion-proof motor will provide a detailed introduction to its working principle and usage precautions.

1、 The working principle of explosion-proof motors:

1. Structure of explosion-proof motor: The explosion-proof motor mainly consists of the motor body, end cover, bearings, stator, and components. The shell structure adopts special corrosion-resistant materials, and metal or non-metallic and refractory materials are added to effectively prevent the generation of sparks.

2. Important components of explosion-proof motors: The important components of explosion-proof motors include the stator, rotor, and their structures. The stator is the core part of an electric motor, composed of iron core, winding, insulation material, etc. The rotor is the driving part of the stator, consisting of a winding, iron core, and shaft. Its working principle is to generate a magnetic field through the current flowing through the winding, causing the rotor to rotate, thereby achieving the normal operation of the motor.

3. Explosion proof principle of explosion-proof motors: Explosion proof motors are mainly designed through explosion-proof covers, barrier equipment, and explosion-proof insulation structures to prevent sparks and arcs inside the motor and reduce the risk of explosion caused by faults and external factors. Its explosion-proof principle is based on characteristics such as safety, explosion resistance, protection, and protection level.

2、 Precautions for using explosion-proof motors:

1. Follow usage regulations: Before using explosion-proof motors, relevant usage regulations must be followed, and operations must be carried out strictly in accordance with the operating manual and safety requirements. It is not allowed to change the design structure and parameters of the motor without permission.                                                                                                                                                                                                                                                                                              

2. Regular maintenance and inspection: Explosion proof motors require regular maintenance and inspection, including regular replacement of lubricating oil, cleaning of dust and debris, inspection of motor insulation status, and fastening of bolts. If any abnormal phenomena are found, they need to be repaired or replaced in a timely manner.

3. Dust and waterproof: Explosion proof motors should avoid contact with water and moisture to avoid causing motor short circuits or insulation damage. In addition, when used in a dusty environment, a dust cover should be installed to prevent dust from entering the interior of the motor.

4. Use reliable power supply: When using explosion-proof motors, a reliable power supply should be selected to ensure that the power supply voltage and frequency meet the motor requirements. Avoid abnormal operation and shortened lifespan of the motor due to unstable or excessively low voltage.

5. Prevention of overload: When using explosion-proof motors, it is necessary to avoid overload operation based on their rated power and load requirements. Overloading can cause motor overheating, damage, and even fire.

6. Pay attention to the operating status of the motor: When using explosion-proof motors, always pay attention to the operating status of the motor. If any abnormal sounds, odors, or heating phenomena are found, the machine should be immediately stopped for inspection, and the fault can be eliminated before continuing to use.

7. Prevention of reverse operation: To ensure the normal operation of explosion-proof motors, it is necessary to avoid reverse operation of the motor. Before installing and starting the motor, it is necessary to ensure correct steering and take corresponding protective measures, such as installing a steering switch.

8. Pay attention to safety during storage and transportation: During the storage and transportation of explosion-proof motors, attention should be paid to protecting the motor casing to avoid external collision and other damage. During transportation, it is necessary to adopt stable packaging and fixation to avoid motor sliding, falling, and other situations.

9. Prevention of external impact: When using explosion-proof motors, they should avoid impact and collision with the outside world to avoid damaging the motor casing and affecting the explosion-proof performance of the motor.

10. Do not overload before power outage: Do not overload and use explosion-proof motors before power outage. Overloading may cause motor damage or malfunction.

Nanyang explosion-proof motor tells you that explosion-proof motors have certain working principles and usage precautions. When using explosion-proof motors, it is necessary to strictly comply with relevant usage regulations, regularly maintain and inspect, pay attention to dust and water prevention, prevent overload, and pay attention to the operating status of the motor. Only by using and maintaining explosion-proof motors correctly can they operate safely and reliably.
