Explosion-proof issues when vacuum pumps are connected by belts
Thread Content
A certain area requires explosion protection, and the water ring vacuum pump is connected by a belt. Check "Code for Fire Protection Design of Petrochemical Enterprises" GB50160-2008 [2019 Edition]: 5.7.7 Combustible gas compressors, liquefied hydrocarbons, and flammable liquid pumps must not use belt drive ； If other rotating equipment within the explosion hazard area must use belt drive, anti-static belts should be used. What we are talking about here is the pump, does it include the vacuum pump?
The second half of the description: Other rotating equipment within the explosion hazard area includes vacuum pumps used in the explosion area.
It doesn’t count! Our company also has it, but please read the other party's reply and you don't need to make any changes. Moreover, the first batch of eliminated equipment (public version) no longer has this type of equipment.
Doesn’t it require an electrostatic belt? Vacuum pumps are not considered flammable gas compressor pumps, but electrostatic belts are required for belts in explosion-proof areas.
This is a vacuum pump with a belt transmission, so you need to use an anti-static belt. The motor of the vacuum pump must also use an explosion-proof motor of the corresponding level.
The medium pumped by the vacuum pump is gas, how can it be called a flammable liquid pump? If the vacuum pump discharge pressure is high, it functions like a combustible gas compressor.

The parameters in the design file are incomplete, the equipment is reused, and there is an explosion-proof motor. I checked the model and found that it is a belt drive. I would like to discuss whether it can be belt driven? If yes, do you want to provide the relevant parameters of the anti-static belt?
If you want to join now, no one will check you. At most, you can switch in a few years, and there will be no problems.
