Turbocharger tseem ceeb parameter

①A/R

Tus nqi A / R yog qhov tseem ceeb ntawm kev ua haujlwm rau turbines thiab compressors. R (Radius) yog qhov kev ncua deb ntawm qhov chaw ntawm lub turbine ncej mus rau qhov chaw ntawm lub ntiajteb txawj nqus ntawm

tuscross-section ntawm lub turbine inlet (los yog compressor qhov hluav taws xob). A (Area) yog hais txog thaj chaw hla ntawm lub tshuab cua nkag (lossis compressor cua qhov hluav taws xob) sib xws rau saum toj no

center ntawm gravity point. Qhov piv tau los ntawm kev faib A los ntawm R thiab muab faib los ntawm 25.4 yog tus nqi A / R.

①Pressure ratio π

Hais txog qhov piv ntawm qhov hluav taws xob compressor qhov hluav taws xob rau lub compressor inlet siab.

π = Tom qab P siab / Ua ntej P siab

P siab yog hais txog qhov siab kawg ntawm qhov hluav taws xob ntawm lub compressor (kPa)

P siab yog hais txog qhov siab kawg ntawm qhov nkag ntawm lub compressor (kPa)

② Inlet cua ntws

Hais txog qhov hnyav ntawm cov pa uas ntws los ntawm lub compressor ib lub sijhawm. Nws chav tsev yog kg / s (unit rau lub rooj zaum xeem yog kg / h).

③ Tag nrho efficiency ntawm supercharger

Tag nrho cov kev ua tau zoo ntawm lub supercharger yog hais txog qhov sib piv ntawm lub zog tso zis ntawm lub supercharger rau lub zog nkag. Nws yog cov khoom ntawm compressor efficiency, turbine efficiency

thiab mechanical efficiency.

④Tsim

Tus nqi Trim yog hais txog qhov sib piv ntawm lub square ntawm cov cua inlet txoj kab uas hla mus rau lub square ntawm cov cua qhov hluav taws xob txoj kab uas hla ntawm lub compressor impeller, multiplied los ntawm 100. Lub turbine trim tus nqi yog

xam los ntawm kev sib piv cov square ntawm qhov chaw nres nkoj txoj kab uas hla nrog lub square ntawm lub intake chaw nres nkoj txoj kab uas hla thiab muab 100.

⑤ Siab piv π

Hais txog qhov piv ntawm qhov hluav taws xob compressor qhov hluav taws xob rau lub compressor inlet siab.

π = Tom qab P siab / Ua ntej P siab

P siab yog hais txog qhov siab kawg ntawm qhov hluav taws xob ntawm lub compressor (kPa)

P siab yog hais txog qhov siab kawg ntawm qhov nkag ntawm lub compressor (kPa)
