Cov thev naus laus zis tseem ceeb ntawm Scroll Compressors
rau Electric Tsheb Cua Txias
Cov hom thiab cov yam ntxwv ntawm cov scroll profile txiav txim siab tag nrho cov kev ua tau zoo thiab kev ua haujlwm ntawm scroll compressor. Yog li ntawd, tsim thiab tsim ib qho scroll profile nrog kev ua tau zoo dua plays lub luag haujlwm tseem ceeb hauv kev tsim thiab tsim cov scroll compressors. Nyob rau hauv cov nqe lus ntawm ib tug profile kab, tam sim no muaj cov nram qab no hom: puag ncig involute, kuj tsis paub meej txoj kab uas hla puag ncig involute, thiab kab segment involute. Ntawm lawv, feem ntau siv hom yog lub hauv paus voj voog involute. Nrog rau kev xav tau ntau ntxiv rau kev siv engineering thiab kev nce qib ntawm kev ua haujlwm thev naus laus zis, scroll compressor tsim thiab tsim nrog cov kab sib txawv ntawm lub hauv paus lub voj voog involute profile tau txhim kho nws cov kev ua tau zoo tag nrho. Nyob rau hauv tib txoj kev ua haujlwm, piv nrog lub voj voog ruaj khov involute linear scroll compressor, qhov sib txawv ntawm txoj kab uas hla hauv qab lub voj voog involute scroll hniav muaj cov qauv kev ntxhov siab zoo dua, lub zog thiab nruj, thiab muaj cov duab zoo dua. zog thiab dynamics.
Txawm li cas los xij, qhov dav siv ib qho profile kuj tseem muaj qhov tsis txaus ntseeg: kev txhim kho ntawm cov duab geometric tshwj xeeb thiab cov qauv nkhaus txwv qhov ntau yam ntawm cov qauv tsim. Yog li ntawd, nyob rau hauv xws li ib tug teeb meem uas tus qauv ntawm ib tug ib tug profile kab rov ua dua, qhov tsim tshwm sim yuam kev yog loj, thiab cov kev pab cuam yog nkim, kev nce qib ntawm universal profile kab yog tsim nyog rau kev tsim ua hauj lwm ntawm cov profile kab, uas. yog qhov tseem ceeb ntawm nws cov qauv kev ua lej sib koom ua ke uas tuaj yeem ua tiav tau zoo Cov qauv geometric tau tsim. Nyob rau tib lub sijhawm, txhawm rau txhawm rau tshem tawm cov kev txwv ntawm cov txheej txheem tsim cov txheej txheem ib txwm muaj, tus qauv parametric tuaj yeem tsim tau raws li cov yam ntxwv ntawm cov kab profile dav dav, thiab cov kab ke ntawm kev sib raug zoo ntawm cov kab sib txuas ntawm cov txheej txheem tswj cov coefficients thiab cov ntsuas kev ua tau zoo tuaj yeem tsim. los ua kom zoo tshaj plaws tsim. Kev tshawb fawb hauv tsev tau siv txoj kev isometric nkhaus los tsim ib qho vortex profile uas muaj cov voj voog thiab arcs. Nyob rau lub hauv paus no, nws tau raug pov thawj los ntawm cov piv txwv hais tias qhov thib ob-kev txiav txim nruam vortex profile yog zoo dua li thawj-txiav mus tas li vortex profile. Nws muaj qhov zoo dua profile-rau-ntim piv thiab aerodynamic stability. Txawm li cas los xij, tsim scroll compressors raws li ib qho kev qhuab qhia lossis ib qho kev ua tau zoo tsis tuaj yeem ua tiav qhov kev ua tiav tshiab. Txhawm rau ua kom cov qauv tsim thiab tsim scroll compressor muaj qhov theoretical, cov tswv yim thiab cov ntawv thov kev lag luam, kev sib koom tes tsim kev sib koom ua ke nrog ntau yam kev qhuab qhia thiab txiav txim siab txog kev ua haujlwm sib txuas ua ke ntawm tag nrho lub tshuab yuav zoo heev hauv kev tshawb fawb yav tom ntej.
Kev ua kom zoo los ntawm kev kho cov hniav txhuam hniav tuaj yeem tsis tsuas yog txhim kho lub zog ntawm cov hniav, tab sis kuj txhim kho tag nrho cov kev ua tau zoo ntawm compressor. Tam sim no, cov kev siv ntau tshaj plaws ntawm kev kho qhov profile yog arc hom thiab linear hniav taub hau hom kab kho. Piv txwv li, cov kws tshawb fawb hauv tsev tau tsim cov qauv geometric ntawm n khub ntawm arc-corrected profiles (n-CMW) raws li arc-corrected profiles, thiab tau txais kev sib cuam tshuam ntawm cov duab geometric thiab cov txiaj ntsig simulation. Nyob rau hauv tib yam kev mob, lub tso zis siab ntawm lub compressor nrog n khub ntawm arc-kho scroll profiles yog ho siab dua li ntawm lub compressor nrog arc-kho scroll profiles, uas ua pov thawj tias lub volumetric efficiency ntawm n-pair arc-kho compressor. zoo dua. . Qee qhov kev tshawb fawb tau muab piv rau cov pa tawm ntawm peb qhov CMP nyob rau hauv tib lub ntim ntim: arc-kho profile, arc-plus-linear hloov profile, thiab asymmetric arc-kho profile. Cov txiaj ntsig tau pom tias: nyob rau hauv tib yam kev mob, arc-kho qhov tso tawm siab ntau dua li ntawm arc ntxiv rau txoj kab ncaj nraim kho profile, thiab compression efficiency ntawm symmetrical kho profile yog zoo dua li ntawm asymmetric kho profile. Txoj kev npaj tsim pab tsim CMP tshiab nrog cov khoom siv kho tshuab zoo dua.
