1. Cov ntsiab lus
JSP Screw lub tshuab nqus tsev twj tso kua mis yog ib hom kev siv thev naus laus zis ntau hom tshuab nqus tsev twj. Nws yog peb lub tuam txhab kev tshawb fawb ywj pheej thiab kev tsim kho raws li kev xav tau ntawm kev ua lag luam. Txij li thaum lub tshuab nqus tsev twj tsis tas yuav tsum muaj lub lubrication lossis dej foob, lub twj tso kua mis chamber yog kiag li tsis muaj roj. Yog li ntawd, lub tshuab nqus tsev twj tso kua mis muaj qhov zoo sib xws hauv cov khoom siv hluav taws xob semiconductor, lub sijhawm uas xav tau lub tshuab nqus tsev nqus tsev vacuum hauv kev lag luam hluav taws xob, thiab cov txheej txheem rov qab los ntawm kev lag luam tshuaj.

2. Pumping Principal
Ntsia hlau hom lub tshuab nqus tsev twj tso kua mis tseem hu ua qhuav ntsia hlau nqus tsev twj. Nws yuav siv sij hawm kom zoo dua ntawm cov iav kis tau tus mob ua rau lub synchronous counter-rotating inter-meshing yam tsis muaj kev tiv tauj ob screws khiav nyob rau hauv ib tug ceev ceev. Nws kuj tseem siv lub plhaub twj tso kua mis thiab cov kauv ntawm kev sib koom ua ke los cais cov kauv zawj, ua kom muaj ntau theem. Gas yog pauv mus rau hauv vaj huam sib luag channel (cylindrical thiab sib npaug pitch), tab sis tsis muaj compression, tsuas yog lub helical qauv ntawm cov ntsia hlau muaj ib tug compression nyhuv ntawm cov roj. Lub siab gradient tuaj yeem tsim nyob rau txhua theem ntawm cov ntsia hlau, uas tuaj yeem siv los cuam tshuam qhov sib txawv ntawm qhov sib txawv thiab nce qhov sib piv compression. Txhua qhov kev tshem tawm thiab kev sib hloov ceev muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm lub twj tso kua mis. Thaum tsim qhov sib txawv ntawm cov ntsia hlau ministries, kev nthuav dav, kev ua haujlwm thiab kev sib dhos raug thiab qhov chaw ua haujlwm (xws li kev tshem tawm cov plua plav uas muaj roj, thiab lwm yam) yuav tsum xav txog. Lub twj tso kua mis zoo li no tsis muaj qhov tso pa tawm zoo li lub hauv paus nqus cov twj tso kua mis. Yog tias xaiv ib qho yooj yim ntsia hlau hniav zoo li seem, nws yuav yooj yim rau kev tsim khoom, tau txais qhov tseeb machining siab thiab yooj yim sib npaug.

3. Cov yam ntxwv zoo
ib. Tsis muaj roj nyob rau hauv lub twj tso kua mis kab noj hniav, tsis muaj kuab paug rau lub tshuab nqus tsev system, zoo dua ntawm cov khoom.
b. Tsis muaj roj nyob rau hauv lub twj tso kua mis kab noj hniav, daws cov teeb meem ntawm cov roj emulsification thiab nquag hloov cov dej ua hauj lwm, nquag tu thiab tu, txuag tus nqi ntawm kev siv.
c. Qhuav khiav, tsis muaj roj pov tseg lossis roj fume, ib puag ncig tus phooj ywg, txuag cov peev txheej roj.
d. Nws tuaj yeem nqus tau nrog cov dej vapor ntau thiab cov hmoov av me me ntawm cov pa. Ntxiv cov khoom siv kuj tseem tuaj yeem nqus cov nplaim hluav taws thiab tawg thiab cov pa hluav taws xob.
e. Qhov kawg siab tuaj yeem ncav cuag 5pa, haum rau nruab nrab thiab qis qis. Nws tuaj yeem nruab nrog cov twj tso kua mis hauv nruab nrab lub tshuab nqus tsev tsis muaj roj, lossis nruab nrog cov twj tso kua mis molecular rau hauv lub tshuab nqus tsev siab tsis muaj roj.
f. Tom qab cov txheej txheem los tiv thaiv corrosion, nws yog tshwj xeeb tshaj yog haum rau transformers, kws, distillation, ziab, degassing nyob rau hauv cov tshuaj ua thiab lwm yam tsim nyog lub sij hawm.

4. Cov ntawv thov
