Do the equipment in the circulating water plant require explosion-proof motors? What are the standards and guidelines?
Depending on the location, explosion protection is required in Class A areas. It might be in the petrochemical fire protection regulations
Actually, it should be used; the distance itself shouldn’t be a problem. The issue is that over time, the circulating water heat exchanger may start to leak internally, and it’s possible for the material to end up in the cooling tower along with the return circulating water
The safety distance is crucial; moreover, the level of attention given also has an impact~~~~ Generally, non-explosion-proof types are used~~~
Where can I find the design specifications for the selection requirements of this equipment?
There are no specific requirements for the circulating water itself; it depends on whether it is located within an explosion-proof area. The explosion-proof area map in our factory was prepared in accordance with the \"Code for Design of Electrical Installations in Explosive Atmospheres\" – GB50058-2014. When selecting electrical instruments, it is necessary to check whether they are situated within an explosion-proof area
In circulating water plants, there are generally requirements for spacing between separate areas and equipment; such spacing requirements can be found in the petrochemical industry standards. If the distance between the circulating water plant and the equipment meets these standard requirements, then explosion-proof motors are not necessary
