The difference between explosion-proof motors and ordinary motors:
1. Different places of use: Explosion-proof motors are generally used in flammable and explosive places.
2. The sealing effect of the junction box is different: the sealing of the explosion-proof motor junction box is better than that of ordinary motors.
3. The protection levels are not exactly the same: the minimum protection level of explosion-proof motors is IP55, while ordinary motors have IPIP23, IP44, IP54, IP55, and IP56.
4. The operating safety is not exactly the same: explosion-proof motors do not produce sparks when running.
5. The main uses are not exactly the same: explosion-proof motors are mainly used to drive pumps, fans, compressors and other transmission machinery in flammable and explosive enterprises such as coal mines, oil and gas, petrochemical and chemical industries.
Extended information
The rated voltage, rated current, power, and speed of explosion-proof motors are the same as those marked on ordinary motors. The difference is that the explosion-proof motor has an explosion-proof mark: Ex.
According to the principle of explosion-proof, explosion-proof motors can be divided into: explosion-proof motors that use explosion-proof shells to isolate electrical parts that may produce sparks, arcs and dangerous temperatures from the surrounding explosive gas mixture; Increased safety motors with electrical and thermal protection measures; positive pressure motors using positive pressure electrical equipment; dust explosion-proof motors and non-sparking motors that can prevent dust from entering the motor housing.
