Nqus hom sab hauv compression scroll twj yog cov khoom siv hluav taws xob uas tau siv dav hauv kev tshawb fawb thiab kev lag luam. Cov peev txheej ntawm lawv cov kev siv suav nrog qee cov txheej txheem thev naus laus zis, vim tias qhov nqus nqus nqus tau tsim. Qhov nruab nrab tsim tau ntawm cov khoom siv yog mus txog 35 cubic meters / h. Vim lub xub ntiag ntawm ib puag ncig qhuav tag, xws li lub twj tso kua mis kuj tseem siv tau rau kev siv cov pa roj. Xav txog cov yam ntxwv thiab cov txiaj ntsig ntawm cov cuab yeej no.
History of Creation
Thawj qhov kev sim los tsim lub twj tso kua mis tuaj yeem suav tias yog qhov ntsuas ntawm huab cua siab nyeem ntawv, ua los ntawm tus kws kho mob Italian lub npe hu ua Torricelli. Tom qab kawm txog cov ntaub ntawv tau txais, nws xaus lus tias muaj lub tshuab nqus tsev, tsis ntev ua pov thawj nws qhov kev xav.
Tus qauv tsim qauv ntawm cov cuab yeej hauv nqe lus nug tau tsim nyob rau thaum pib ntawm lub xyoo pua 18th raws li qhov project ntawm Fabkis engineer Leon Croix. Tus kws tshawb fawb tau tsim ib lub tswv yim raws li cov khoom siv teb nrog ob qho tib si-pitch spirals. Nyob rau tib lub sijhawm, ib qho ntawm cov ntsiab lus tseem ruaj khov thiab txuas nrog lub cev. Qhov thib ob kauv swb nyob rau hauv sab hauv raws txoj kev orbital.
Serial ntau lawm ntawm kauvLub tshuab nqus tsev twj tso kua mis tau tsim txij li xyoo 1980. Thawj cov qauv muab cov cua rho tawm thiab kev ua haujlwm siab rau cov motors thiab cov cua txias. Tam sim no txoj kev siv cov compressors tau nthuav dav, suav nrog kev lag luam, chaw tsim khoom, thiab kev lag luam. Kev hloov kho kauv feem ntau yog ua haujlwm hauv chav kuaj thiab chaw lag luam.
Ntse
Ob lub kauv nyob nruab nrab ntawm ib leeg ntawm kaum ntawm 180 degrees. Lawv tsim crescent-shaped compartments nyob rau hauv uas lub zog ntawm cov pa yog muab los ntawm lub siab sib txawv nyob rau hauv lawv. Lub tshuab hluav taws xob xa hluav taws xob xa mus rau lub tog raj kheej, tom qab ntawd cov spirals ua rau lub orbital txav, thiab lub ntim ntawm cov pa, maj mam shrinking, nyhav rau hauv nruab nrab.
Cov khoom siv li no yog nyob rau hauv chav kawm ntawm fore-vacuum scroll pumps of dry type with internal compression. Cov qauv tsim tsis muab rau kev siv roj los kaw cov ntsiab lus mating. Cov twj tso kua mis hauv nqe lus nug tuaj yeem ua haujlwm nyob rau hauv cov xwm txheej uas muaj qhov ua tau zoo ntawm condensation.
Pros
Qhov zoo ntawm cov twj scroll:
- Qhov tsis muaj roj vapor ua tiav tso cai rau kev siv cov khoom siv los tsim cov tshuaj dawb huv hauv lub tshuab nqus tsev.
- Thaum lub sijhawm ua haujlwm, abrasives tsis ntim rau sab hauv, uas ua rau lub neej ntev ntawm cov khoom siv kho tshuab, ua kom muaj kev ruaj ntseg coefficient.
- Tsis muaj suab nrov thiab kev vibration qis ua rau nws siv tau cov cuab yeej hauv cov chav uas muaj neeg.
- pib thiab pib lub twj tso kua misyuav tsum tau siv zog tsawg heev.
- Cov cuab yeej yog lub teeb yuag, tsis tas yuav muaj cov ncej tshwj xeeb lossis thav duab rau kev thauj mus los.
- Compact. Tseem muaj kev hloov kho desktop.
- Kev ntseeg tau ntawm cov khoom siv tshuab thiab cov khoom siv hluav taws xob.
- Cov chav nyob tau nruab nrog cov tshuab tshwj xeeb rau kev sib khi, sib khi, cov plua plav thiab cov khib nyiab tshem tawm.
- High efficiency (kwv yees 95%).
- Dav kev khiav hauj lwm siab ntau thiab siab precision twj tso kua mis xaiv.
- Cov cua sov tawm tsawg kawg nkaus, muaj qhov ua kom muaj cua txias tag nrho.
- Yuav luag txhua tus qauv yog nruab nrog ib teev 'meter', tsis tas yuav tsum tau ua haujlwm nyuaj thiab kim kim.
pob
Tus tsim ntawm lub twj tso kua mis sib txawv los ntawm cov chaw tsim khoom, tab sis txhua tus qauv tsim muaj xws li:
- Forged hlau lub cev, semi-thick coated.
- Stand (nruab deb ntawm qhov txav txav tau los ntawm 0.05 txog 0.01mm).
- Counterweight mechanism.
- Tsiv ib feem uas ua rau kev sib hloov.
- Anti-jamming device.
- Eccentric ncej (tsim hluav taws xob).
- Ib lub hauv siab uas kaw cov pob qij txha kom tiv thaiv kev qhia cov roj vapors.
- Roj resistant roj hmab foob.
Nws ua haujlwm li cas?
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub twj tso kua mis scroll yog rauKev tshem tawm cov pa roj los ntawm qhov chaw nruab nrab mus rau qhov chaw uas siv cov khoom txav tau uas tsim tau ob lub voj voos kheej kheej. Tom qab ntawd lub ntim tau muab tso rau hauv chav tsev thiab lub qhov nyob hauv nruab nrab ntawm lub phaj kawg ntawm lub txaj ruaj.
Tus naj npawb ntawm kev sib hloov ntawm lub voj voog ua haujlwm tag nrho nrog ib feem ntawm cov pa roj yog zoo ib yam rau cov lej ntawm cov kauv. Rau qhov no, lub involute, Archimedes kauv, ntau yam arcs ntawm lub voj voog thiab lawv cov variations yog siv.
Qhov sib txawv tseem ceeb ntawm kev ua haujlwm ntawm chav tsev nyob rau hauv nqe lus nug yog qhov nqus, compression thiab tawm yog ua tiav synchronously, ib txhij nyob rau hauv ob peb kab noj hniav. Diffusion ntawm cov pa nruab nrab ntawm qhov qis thiab siab siab sectors raug txo vim yog kev sib cais ntawm cov ntim ntawm lawv. Qhov kev txiav txim siab no ua rau nws tuaj yeem tso tseg kev siv cov pa tawm thiab nqus cov li qub.
Anest Iwata Scroll Pumps
Cov chav no tau tsim los ntawm lub tuam txhab Nyij Pooj txij li xyoo 1990.
