Scope

Scope: This document specifies the technical requirements, test methods, inspection rules, marking, labeling, random documents, packaging, transportation, and storage of single-shaft multi-stage centrifugal vacuum pumps (hereinafter referred to as "multi-stage centrifugal vacuum pumps"). This document does not include complete gear-speed-up type units. It is applicable to single-shaft, multi-impeller, multi-inlet, single-outlet units with an external gearbox, capable of generating one to four different vacuum levels. This document is suitable for single-shaft multi-stage centrifugal vacuum pumps with an outlet pressure of atmospheric or positive pressure, an inlet vacuum range of 20 kPa to 80 kPa or a total pressure ratio of 1.3 to 5, and a transport medium of dry air, saturated humid air containing liquid water, and other non-corrosive, non-flammable, and non-explosive gases. The dust content should be ≤10 mg/m3, and the water droplet diameter should be <10 μm.
