Scope

Scope: This document specifies the classification, technical requirements, test methods, inspection rules, warranty period, marking, packaging, storage, and transportation of adjustment doors for centrifugal fans (hereinafter referred to as "adjustment doors"). This document applies to intake adjustment doors for centrifugal fans with a maximum pressure not exceeding 20 kPa, where the transported medium is air or a mixture of air and other weakly corrosive gases. The medium flow temperature does not exceed 250°C, the dust content and other solid impurities do not exceed 400 mg/m3, and there are no sticky materials. For adjustment doors used in scenarios where the fan pressure exceeds 20 kPa, the medium flow temperature exceeds 250°C, or the dust content and other solid impurities exceed 400 mg/m3, the structural form may refer to this document, and the stiffness and strength shall be designed separately.
