ActiveVapour vacuum pumps-Measurement of performance characteristics Part2:Measurement of critical backing pressure
蒸汽流真空泵性能测量方法 第2部分：临界前级压力的测量
Application Summary AI generated
This standard specifies the method for measuring the critical backing pressure of vapour vacuum pumps, which is the maximum discharge pressure the pump can tolerate while maintaining stable operation. It is applied in the testing and performance evaluation of vapour jet and diffusion pumps used in industrial vacuum systems, such as those in semiconductor manufacturing, coating, or metallurgical processes. The standard ensures consistent measurement procedures for comparing pump performance under varying backing pressure conditions.
