Explosion-proof motors for Class A equipment
Thread Content
The water-coal slurry gasification area is classified as Category A; at what distance from the slurry pump is it not necessary to use explosion-proof motors?
It is necessary to conduct a hazard zone classification to determine the specific scope. If needed, you can add me on WeChat: 13405802458 to work on this together. Wishing you a happy New Year!
Please refer to the requirements of GB50058 for classification; it cannot be explained in just one sentence!
The process engineering team submits a medium survey form to the electrical engineering team, which then prepares a map showing the areas classified as explosive hazard zones, based on the equipment layout and other factors. It is determined which zone this pump falls into, and accordingly, an explosion-proof design is selected for it.
Is there Class A material in the material pump? If so, explosion protection is almost essential
Give a thumbs up to Yu Qin, the moderator who is still managing the forum during the Spring Festival holiday – thank you for your hard work!
Determined according to the explosion hazard zone classification map. Those located in explosion-hazardous areas should use explosion-proof ones.
Let professionals handle professional tasks; have the design institute do the verification.
It’s better to get the explosion zone classification diagram from the design institute; don’t try to figure it out on your own
