Glass-lined agitator - Retreat curve impeller type
1 Scope
This standard specifies the type, basic parameters, main dimensions, requirements, packaging, transportation and storage of the glass-lined agitator—retreat curve impeller （RCI）type. This standard is applicable to the retreat curve impeller agitator of the glass-lined agitating vessels with a nominal volume of 50L-40 000L, a design temperature of -20℃ - 200℃, a nominal turning speed 70r/min - 125r/min and the linear velocity of the end of the blade of the agitator is no more than 8m/s.
