LIQUID FLOW RATE CONVERTER

摘要

single-jet impeller converters. SUBSTANCE: converter has housing with inlet and outlet branch pipes; each branch pipe is communicated with one of two holes available in side wall of impeller module secured inside housing. Surfaces of impeller blades are provided with grooves of fins located in parallel relative to axis of rotation. EFFECT: increased service life of flow rate meters due to wear resistance of impeller through reduction of hydrodynamic load on axle and bearing bushes. 9 dwg
