1. , a kind of performance diagnogtics device of fluid machinery is characterized in that,Have anticipation performance curve arithmetic mean unit and performance diagnogtics arithmetic mean unit, wherein, above-mentioned anticipation performance curve arithmetic mean unit according to the compression ratio of fluid machinery or pressure difference and inlet flow rate to each of a plurality of fluid controlled quentity controlled variables with the characteristic nondimensionalization, obtain the curve of the relation between expression pressure coefficient and the flow coefficient;

  • Fluid controlled quentity controlled variable, suction pressure, head pressure, inlet temperature, compressibility coefficient, gas mean molecule quantity, heat capacity ratio when above-mentioned performance diagnogtics arithmetic mean unit moves according to above-mentioned fluid machinery, obtain measured performance pressure reduction, and according to anticipation performance curve, fluid controlled quentity controlled variable and inlet flow rate, obtain anticipation performance pressure reduction, according to the ratio of anticipation performance pressure reduction and measured performance pressure reduction, operational performance impairment grade.
