This post was last edited by tayoutu on 2025-7-28 00:40. A certain area requires explosion protection, and water ring vacuum pumps are connected using belts. Refer to the \"Code for Fire Protection Design of Petrochemical Enterprises\" GB50160-2008 [2019 edition]: 5.7.7 Belt drives shall not be used for combustible gas compressors, liquefied hydrocarbon, and combustible liquid pumps ; If belt drives must be used for other rotating equipment within the explosion-hazardous area, anti-static belts should be employed. It refers to pumps here; does it include vacuum pumps?
