Vertical long axis pump using explosion-proof motor and dust explosion-proof difference

Type of long axis pump manufacturers Lijia pump on the explosion-proof motor, there are a lot of differences between dustignitionproof motors and ordinary explosion-proof motor to believe that everyone is only partly understood relative, is no dust explosion proof motor of explosion-proof motor high protection level, will be relatively safe, in fact, in the use of either gas explosion proof motor the place or places of dust explosion. Will we choose to use explosion-proof motor, explosion-proof motor principle from different can know, the protection grade of explosion-proof motor is lower than the dust explosion proof motor, if the gas explosion proof motor directly to the site in the dust, dust will accumulate in the way of explosion-proof motor, vertical long shaft pump performance of the explosion-proof motor to reduce to unsafe normal operation.

Someone should ask, is it possible to dust explosion-proof motors into the gas explosion site? This is no good, dustproof and explosion-proof motor is a high level protection package shell only, can not stop the explosion of gas into the dust explosion proof motor inside, no explosion, increased safety and other protective measures, so this is not a change to use.

In many explosive dusts there are many,

Can be divided into four kinds: explosive dust, flammable conductive dust, flammable, non conductive dust and combustible fiber.
