中文简体①Pressure ratio π
Refers to the ratio of the compressor outlet pressure to the compressor inlet pressure.
π=After P pressure / Before P pressure
After P pressure, it refers to the absolute pressure at the outlet of the compressor (kPa)
Before P pressure refers to the absolute pressure of the compressor inlet (kPa)
②Intake air flow
Refers to the weight of the gas flowing through the compressor per unit time. The unit is kg/s (the unit is kg/h during the bench test).
③Total efficiency of supercharger
The overall efficiency of the supercharger refers to the ratio of the output energy of the supercharger to the input energy. It is the product of compressor efficiency, K03 Turbocharger 53039880106 efficiency and mechanical efficiency.
④Trim value
The Trim value refers to the ratio of the square of the diameter of the air inlet to the square of the diameter of the air outlet of the compressor impeller, multiplied by 100. Turbo Trim value, multiplied by 100 by comparing the square of the diameter of the exhaust port and the square of the diameter of the intake port.
⑤A/R value
The A/R value is an important performance parameter for turbines and compressors. R (Radius) is the distance from the center of the turbine shaft to the center of gravity of the cross section of the turbine inlet (or the compressor outlet). A (Area) refers to the cross-sectional area of the turbine inlet (or the compressor outlet) corresponding to the above center of gravity. A/R is the ratio obtained by dividing A by R and dividing by 25.4.
