Compression ratio (siab piv, siab piv)
ⅰ. Internal compression ratio (piv txwv li, internal pressure ratio)
Qhov piv ntawm qhov kawg siab (siab kawg) rau qhov pib siab (siab siab) ntawm cov roj tom qab compression sab hauv.
Ii. Sab nraud compression ratio (piv txwv li sab nraud siab piv)
Qhov piv ntawm qhov hluav taws xob tso siab (siab siab) rau inlet suction siab (siab siab) ntawm lub compressor.
Rau cov ntsia hlau cua compressor, qhov sib piv sab hauv yog hais txog qhov sib piv ntawm cov ntsia hlau lub tshuab nqus tsev thiab qhov chaw nres nkoj (qhov siab kawg), thiab qhov sib piv sab nraud yog hais txog qhov sib piv ntawm cov cua compressor nqus thiab qhov chaw nres nkoj (qhov siab kawg) .
Feem ntau hais lus, qhov sib piv compression ntawm cua compressor yog hais txog qhov sib piv ntawm cov compression sab nraud, qhov nqus siab yog hais txog lub hauv paus atmospheric siab, thiab qhov tso pa tawm yog hais txog kev ua haujlwm siab ntawm lub tshuab cua compressor, xws li UD110-8, Cov pa tawm siab yog 8bar, thiab qhov sib piv compression yog 9.
Rau multistage compressors, qhov sib piv siab, tseem hu ua tag nrho cov siab piv, yog hais txog qhov sib piv ntawm cov pa tawm siab ntsuas ntawm qhov kawg ntawm cov yeeb nkab nozzle thiab qhov nqus siab ntsuas ntawm thawj cov yeeb nkab. Qhov piv ntawm qhov sib thooj nominal suction thiab tso siab yog hu ua lub siab piv ntawm theem.
