In view of the explosion-proof requirements in dust environments, the common explosion-proof levels of dust explosion-proof motors are as follows:
ExD: The explosion-proof motor housing is explosion-proof, which can withstand internal explosions by itself and will not cause explosions in the surrounding environment. It is suitable for severe dust environments, such as areas where combustible dust accumulates in thick layers.
ExtD: The explosion-proof motor housing is explosion-proof, but its protective measures are more stringent than the ExD level to prevent explosions caused by external sparks or high temperatures. Suitable for general environments where combustible dust exists.
ExDe: The explosion-proof motor housing is explosion-proof and has additional protective measures to prevent dust from entering the motor and causing an explosion. Suitable for environments with obvious dust.
ExI: The interior of the explosion-proof motor adopts a flameproof design to prevent internal combustibles from contacting the external combustible environment and avoid explosions. It is suitable for environments where fine dust exists and a high degree of protection is required.
It is necessary to select the appropriate explosion-proof level of dust explosion-proof motor according to the dust characteristics in the actual working environment and the classification level of explosion hazardous areas. In addition, appropriate safety regulations and requirements must be followed for proper installation, operation and maintenance.
