Nachi roj twj tso kua mis muaj 3 qhov muaj peev xwm sab hauv to: cov hniav sab hauv to ntawm cov hniav meshing, radial to ntawm lub twj tso kua mis chamber thiab ib ncig ntawm sab saum toj ntawm cov hniav, thiab kawg lub ntsej muag to (axial to) ntawm cov hniav kawg thiab cov npog kawg ib feem, ntawm qhov kawg lub ntsej muag to leakage muaj qhov loj tshaj plaws ntawm to.
1, hniav sab to - txog 5% ntawm tag nrho cov to ntawm nachi roj twj.
2, radial to - nyob rau hauv lub nachi roj twj tso kua mis nyob rau hauv tag nrho cov feem ntawm 20% mus rau 20%
3, kawg lub ntsej muag to -75% ~ 80% ntawm tag nrho cov to ntawm nachi roj twj
Nachi roj twj tso kua mis ntawm qhov siab dua, vim nws qhov kev tshem tawm loj, yog li muaj qhov xau loj, yog tias tsis kho cov txheej txheem, tab sis tsuas yog siv rau qis dua, kev ua haujlwm ntawm compression ntawm nws cov ntim yog tsawg heev.
Yog li ntawd, ua kom nachi roj twj ncav cuag siab, txhim kho lawv cov kev ua hauj lwm siab thiab volumetric efficiency. Nws yog ib qho tsim nyog yuav tsum tau ua cov qauv ntsuas kom them nyiaj rau qhov kawg qhov sib txawv.
