METHOD OF DETERMINATION OF DISTRIBUTION OF FLOW VELOCITY CIRCULATION IN MEASURING SECTIONS OF IMPELLER PUMP |
摘要 |
FIELD: development of working members of impeller pumps, turbines, compressors, fans, etc. SUBSTANCE: system of independent coaxial measuring cascades is placed at inlet and outlet of blade cascade of impeller and guide vane assembly for determination of distribution of circulation of velocity of axisymmetric flow in measuring sections of stages of impeller pumps. Measuring cascades are so positioned that their trailing below to measuring section of flow. Then hydrodynamic moment acting on each cascade and supply of working medium flowing through each cascade respectively are measured. EFFECT: enhanced efficiency. 6 dwg
