- Scope
- JB/T 8671-1997 This standard is formulated based on my country's current standards and explosion-proof regulations for three-phase asynchronous motors. This standard specifies the type, basic parameters, technical requirements, test methods and inspection rules, marking, packaging and warranty period requirements of flameproof three-phase asynchronous motors for TBGB and YBGB-W series pipeline pumps. This standard applies to flameproof three-phase asynchronous motors for 0.55~200kW YBGB series pipeline pumps and flameproof three-phase asynchronous motors for YBGB-W series pipeline pumps. The explosion-proof performance of this series of motors complies with the requirements of GB 3836.2 and is made of explosion-proof type. The explosion-proof marks are dⅡAT4 and dⅡBT4. It is suitable for places with explosive mixtures of flammable gases or steam and air in Class IIA and Class IIB factories with temperatures of T1~T4 groups respectively. .
