Glass-lined agitator - Pitch blade turbine type
1 Scope
This standard specifies the type, basic parameters, main dimensions, requirements, packaging, transportation and storage of the glass-lined agitator—paddle agitator(pitch blade turbine type).
This standard is applicable to the paddle agitator of the glass-lined mixing vessels with a nominal volume of 50L-40000L, 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 7m/s.
