Lub rotor profile yog txhais raws li kab ntawm kev sib tshuam ntawm rotor tus hniav nto thiab lub dav hlau perpendicular mus rau lub rotor axis. Nws evolution tau nce mus txog peb tiam: thawj tiam featured symmetric ncig arc profiles; tiam thib ob qhia txog asymmetric profiles nrog cov hniav nkhaus uas muaj cov ntsiab lus, cov kab ncaj nraim, thiab cycloids; thiab tiam thib peb tau siv asymmetric profiles nrog cov nkhaus xws li ncig arcs, ellipses, thiab parabolas. Cov qauv tsim ua ntej rau rotor profiles hais tias txoj kab sib txuas yuav tsum luv thiab txuas ntxiv, thaj tsam ntawm lub tog raj kheej thiab cov ntim ntim yuav tsum raug txo kom tsawg, thiab thaj tsam ntawm cov hniav yuav tsum ua kom tiav.
Hauv cov roj txhaj cov ntsia hlau compressors, cov roj lubricating ua haujlwm ntawm lubrication, txias, thiab sealing. Cov roj txhaj tshuaj feem ntau yog txiav txim siab raws li lub compressor lub thermal sib npaug sib npaug. Compressor roj yuav tsum tau siv sij hawm ntev nyob rau hauv high-temperature, high-pressure ib puag ncig; Yog li ntawd, nws yuav tsum tau zoo heev kub-kub oxidation stability, tsawg carbon-forming tendencies, tsim nyog viscosity thiab viscosity-kub yam ntxwv, nrog rau zoo roj-dej sib cais, xeb tiv thaiv, thiab corrosion kuj.
Kev xaiv cov kabmob yuav tsum coj mus rau hauv tus account kom ntseeg tau tias lub neej ua haujlwm zoo ib yam thoob plaws txhua qhov bearings. Lub sealing system ntawm cov ntsia hlau compressor lub ntsiab chav tsev feem ntau muaj ib lub foob nyob rau hauv lub discharge kawg (roj foob) thiab ib lub foob ntawm lub suction-kawg casing ncej txuas ntxiv (gas foob).
Kev Tswj Xyuas Kev Ua Haujlwm Technology
Twin-ntsia hlau compressors siv lub swb valve mechanism kom ua tiav kev tswj tsis muaj peev xwm. Lub swb valve enables nruam tswj kev muaj peev xwm; los ntawm kev txav lub valve tom qab, qhov zoo compression ntim tau nce lossis txo qis, yog li tswj cov roj xa tawm.
