Hais tias ntau yam tau tshwm sim nyob rau hauv lub xyoo txij li thaum pib ntawm tus kab mob COVID-19, qhov no yog qhov tsis txaus ntseeg ntawm cov xwm txheej epic, ntau heev kom nws nyuaj rau nco qab txog cov hnub qub ntawm cov cuab yeej cuab yeej cuab tam cov zej zog uas siv ntau. - tsim PPE cov tshuaj tiv thaiv., Lub tshuab ua pa hauv tsev thiab lwm yam.Txawm li cas los xij, peb tsis nco qab tias muaj kev sim ntau dhau los tsim qhov DIY oxygen concentrator thaum pib nthuav dav.
Muab qhov yooj yim thiab kev ua tau zoo ntawm tus tsim hu ua OxiKit, nws zoo li coj txawv txawv uas peb tsis tau pom ntau yam khoom siv no.OxiKit siv zeolite, cov ntxhia ntxeem tau uas tuaj yeem siv los ua molecular sieve.Cov hlaws me me tau ntim rau hauv lub tog raj kheej ua los ntawm cov kav dej PVC thiab cov khoom siv los ntawm lub khw muag khoom kho vajtse, thiab txuas nrog lub tshuab cua tsis muaj roj los ntawm lub pneumatic valve tswj los ntawm ntau lub solenoid li qub.Tom qab txias hauv lub raj tooj liab, cov cua compressed raug yuam kom dhau los ntawm zeolite kem uas nyiam khaws cov nitrogen thaum tso pa tawm mus.Cov kwj pa oxygen yog sib cais, ib feem nkag mus rau hauv lub tank tsis, thiab lwm qhov nkag mus rau hauv qhov hluav taws xob ntawm lub zeolite ntauwd thib ob, qhov uas cov kua nitrogen raug tso tawm.Lub Arduino tswj lub valve kom hloov pauv cov roj rov qab los tsim 15 litres ntawm 96% ntshiab oxygen ib feeb.
OxiKit tsis yog optimized zoo li kev lag luam oxygen generators, yog li nws tsis yog tshwj xeeb nyob ntsiag to.Tab sis qhov no yog ntau pheej yig dua li chav ua lag luam, thiab rau feem ntau cov hackers, nws yooj yim los tsim.OxiKit tsim yog txhua qhov chaw qhib, tab sis lawv muag cov cuab yeej thiab qee qhov nyuaj-rau-nrhiav qhov chaw thiab khoom siv, xws li zeolite.Peb yuav sim tsim ib yam dab tsi zoo li no vim tias cov cuab yeej siv tau zoo heev.Muaj cov pa oxygen txaus los tsis yog lub tswv yim phem.
15 litres ib feeb zoo li impressive.Raws li kev ntsuas, nws txaus los txhawb nqa lub neej ntawm 7 tus neeg nyob rau hauv ib txwm muaj xwm txheej (txhua tus neeg @ 2 litres ib feeb).
Kuv ib txwm xav paub seb cov haujlwm no ua haujlwm li cas.Txaus siab.Nws zoo li yuav luag ua txhaum txoj cai ntawm thermodynamics, tab sis nws tsis yog li ntawd.
Nrog rau cov pa oxygen ntau npaum li no, kuv xav paub tias yuav muaj dab tsi tshwm sim yog tias koj dai tus menyuam no rau ntawm lub cav tsheb thiab / lossis nws loj.Tej zaum nws yuav zoo li nitrite.Qhov no yuav muaj kev nyab xeeb heev, vim tias koj tuaj yeem teeb tsa nws kom cov "ntshiab" oxygen uas tsim tau raug siv tam sim ntawd ze ntawm lub cav es tsis txhob khaws cia nyob qhov twg.Txawm li cas los xij, kuv yuav tsum tau kho lub tsheb ua ntej.Backfired… “Nws yuav phem.”
Kuv xav tias qhov no yog qhov zoo rau kev vuam / brazing / txiav cov pa oxygen / propane, oxygen / hydrogen lossis oxygen / acetylene.
Yog lawm, tom qab kuv tau saib daim vis dis aus no, YT tau nthuav tawm Dalbor Farny cov yeeb yaj kiab tawm tswv yim ntawm O2 concentrator.Lub hom phiaj yog muab cov pa oxygen roj teeb uas nws xav tau rau lub iav tshuab tshuab.Tsim koj tus kheej customized digital tube.Qhov tseeb, rau ntawm lawv ua ke los tsim 30 lpm O2.
Kuv kwv yees lub cav 2-liter khiav ntawm ob peb txhiab RPM yuav haus 15-liter cav es tsis txhob 1 feeb.Txawm li cas los xij, qhov no puas tuaj yeem nce qib oxygen hauv huab cua kom txaus?yeej tsis paub
Nitrite tuaj yeem muab lub zog vim tias nws tso tawm nitrogen molecule rau txhua qhov decomposed nitrous oxide molecule (nws tuav nws lub ntim raws li oxygen tau noj), ib yam li nws ua kom cov pa oxygen concentration (tso tawm kuj yuav muab cov cua sov).Pumping oxygen ntshiab tsis yog qhov zoo, vim tias koj tseem poob ntim thiab yuav tsum tau cuam tshuam nrog cov teeb meem uas yuav ua rau lub cav thaiv.
Koj yuav tau scale nce tiag tiag.Lub cav 2-liter tsheb nrog ceev ntawm 2500 rpm "ua pa" kwv yees li 2.5 cubic meters ntawm huab cua ib feeb (21% O²).Nws yog kwv yees li 600 npaug ntawm tib neeg thaum so.Cov pa ntim tau siv los ntawm tib neeg yog li 25% ntawm O², thaum lub tshuab ua pa tau siv los ntawm tsheb yog li 90%…
Nws kuj kub heev thiab molten pistons.Los ntawm tilting cov roj sib xyaw, koj tuaj yeem tau txais ntau lub zog los ntawm txhua lub cav.Tab sis lub piston yuav yaj vim qhov nce hauv tshav kub.Cov ntsiab lus oxygen qis dua tiv thaiv cov hlau los ntawm melting.
Cov cav tsheb zoo tib yam yog txwv los ntawm airflow thiab yuav tsim lub zog siab tshaj plaws thaum combusting tag nrho cov pa hauv huab cua.Qhov no yog ua tiav los ntawm me ntsis enriching cov sib tov, uas tsis hlawv ib co roj av.Tshwj tsis yog tias yuav tsum muaj lub zog siab tshaj plaws, lub cav tsheb feem ntau khiav ntawm qhov qaij me ntsis, vim tias kev ua haujlwm roj nplua nuj txhais tau tias txo qis kev lag luam roj thiab ua kom muaj kuab paug hydrocarbon.
Yog tias koj xav siv qhov tshwj xeeb no kom muaj zog, koj xav tau ib txoj hauv kev los ntxias lub tshuab computer kom ntxiv ib feem pua ​​​​ntawm cov roj tib lub sijhawm.
Yog tias koj tuaj yeem khaws cov huab cua-roj piv tsis tu ncua, nws zoo ib yam li qhib lub throttle los ntawm ob peb feem pua.
Txawm li cas los xij, yog tias koj tshaj li "ob peb feem pua" (kev txhob txwm tsis meej pem ...), koj tuaj yeem ncav cuag qhov kev txwv ntawm ECU lub peev xwm kom nkag siab tias huab cua nkag mus npaum li cas, lossis tswj cov roj ntws tawm ntau npaum li cas, lossis teeb tsa lub sijhawm hluav taws xob kom raug txawm tias ceev npaum li cas. thiab airflow koj siv.
Tus nqi ntws xav tau los ua kom ib tus neeg muaj sia nyob feem ntau nyob ntawm lawv tus mob!2 l / min yog qhov yooj yim.Ntau tus neeg mob xav tau kev saib xyuas hnyav xav tau 15 l / min.
Tsuas yog ceev faj kom tsis txhob muaj oxygen.Cov pa oxygen siab ntau tuaj yeem ua rau ntau yam khoom siv hluav taws xob thiab txhawb kev sib txuas ua ke ntawm ntau cov roj thiab lubricants.Qhov no yog vim li cas lawv siv roj-dawb compressors.
Qhov ntawd, thiab ntau lwm yam "tsis yog tam sim ntawd intuitive" O2 cov txheej txheem tuaj yeem ua mob rau koj, tshwj xeeb tshaj yog nyob rau hauv siab.
Yog tias koj tab tom ua si O2, koj tuaj yeem siv Vance Harlow's Oxygen Hacker's Companion (nitrox divers twb muaj tus khub no): http://www.airspeedpress.com/newoxyhacker .html
Kuv tsis paub phau ntawv, nws yog tus neeg siv, tsis yog tus tuner.Txawm li cas los xij, ua tsaug rau koj qhov kev siv, kuv yuav xaj ib daim ntawv sai li sai tau thaum daim foos siv tau!
Yog, kuv yuav hais.Hom tsis ua hauj lwm ntawm PVC compressed cua yog shrapnel tawg, yog li saib cov kev ntsuas siab ua tib zoo-raws li txoj kab uas hla ntawm cov yeeb nkab nce, qhov ntsuas siab yuav txo.
Thaum xyoo 1980, kuv tau ua haujlwm rau lub tuam txhab leasing khoom siv kho mob uas xauj thiab pab Devilbiss oxygen generators.Thaum lub sij hawm, cov chav no tsuas yog qhov loj me me ntawm npias lub tub yees.Kuv kom meej meej nco ntsoov "hardware cia" xwm ntawm nws cov qauv sab hauv.Kuv tseem nco ntsoov tias lub txaj sieve tau tsim nrog 4-nti PVC yeeb nkab thiab npog, yog li cov qauv tau piav qhia hauv qhov project no yog ua raws li keeb kwm yav dhau los (tab sis pom tseeb siv tau) thev naus laus zis.
Lub compressor yog ob-oscillating piston / diaphragm hom, yog li tsis muaj roj hauv cov cua compressed.Lub valve hauv lub taub hau compressor yog nyias stainless hlau reed.
kwj sorting yog ua los ntawm ib tug neeg kho tshuab timer, tsis muaj Arduino yuav tsum tau.Lub timer muaj ib qho synchronization (clock gear motor) uas tsav lub ncej nrog ntau lub cam log.Lub micro hloov caij ntawm lub cam hluav taws xob solenoid valve, ua rau cov pa txav mus los.
Cov yeeb ncuab loj tshaj plaws ntawm cov tshuab no yog cov av noo siab.Lub adsorption ntawm dej molecules rhuav tshem lub sieve txaj.
Tsuas yog ua ntej kuv tawm hauv lub tuam txhab, peb tau pib nrhiav tau tus neeg pom zoo los ntawm tus neeg sib tw ntawm Devilbiss (lub npe tam sim no tsis paub rau kuv), thiab lub tuam txhab tau pom tias muaj kev vam meej.Ntxiv rau qhov me me thiab ntsiag to tshiab concentrator, lub tuam txhab kuj tau tsim lub sieve txaj siv txhuas raj.Lub raj yog them nrog lub phaj nrog machined grooves rau O-rings.Kuv zoo li xav txog kev txhawb nqa tag nrho uas sib koom ua ke.Qhov zoo ntawm qhov tsim no yog tias tsim nyog, lub txaj tuaj yeem sib cais thiab cov khoom siv sieve tuaj yeem hloov tau.Lawv kuj tau tshem tawm cov neeg kho tshuab timers thiab hloov lawv nrog cov khoom siv hluav taws xob yooj yim thiab SSRs kom ua rau cov solenoids.
Lawv xav tau kev siv SCH40 piping ( ntsuas siab 260psi @ 3 ″) thiab kom meej meej nruab nrog 40psi kev nyab xeeb valve thiab 20-30psi regulator ua ntej PVC yog pressurized, yog li muaj kev nyab xeeb zoo.Tsis paub meej li cas nws yuav raug O2 Hloov qhov siv.
Qhov tawg siab ntawm SCH40 yog ntau zaus ntawm qhov ntsuas siab-nyob ntawm txoj kab uas hla.3-nti yeeb nkab yog kwv yees li 850 psi, thiab 6-nti yeeb nkab yog kwv yees li 500 psi.1/2 nti yog ze rau 2000 psi.Muab ob npaug rau SCH80.Qhov no yog vim li cas PVC ntaus pob tesniv launchers tsis tawg-ntau dhau.Ua kom lawv loj hlob mus rau 6 lossis 8 nti combustion chamber yuav ua rau koj muaj hmoo.Tab sis nyob rau hauv dav dav, lub zej zog hacker nyhav rau underestimate lub zog ntawm cov yas pawg.https://www.pvcfittingsonline.com/resource-center/strength-of-pvc-pipe-with-strength-chart/
Kuv xav kom txo qis cov neeg nyiam ua haujlwm siv hluav taws xob (thiab tejzaum nws yog purity).Kev ua lag luam hobby feem ntau yuav cov khoom siv kho mob cov pa oxygen.Qhov ntawd yog kuv thawj lub tswv yim, tab sis tus nqi ntawm cov khoom siv + BOM deb tshaj tus nqi ntawm chav kho mob so haujlwm.
Lub cav tsheb 2 liter tuaj yeem haus 9,000 litres / feeb ntawm cov pa oxygen (siab ceev), yog li 15 litres / feeb ntawm cov pa oxygen yog li 600 zaug luv dua., Qhov no yog ib qho khoom siv txias.Kuv yuav ob peb refurbished concentrators ntawm 5 litres ib feeb rau $300 txhua (tus nqi zoo li yuav nce).Nws tsim 5 litres / feeb.Ob peb puas watts yog siv, yog li nws yog extrapolated tias 9000 litres ib feeb (rau kev lom zem xwb) yuav tsum tau kwv yees li 360 kW (480 hp).
Vim tias lawv cov algorithm tau sau los ntawm Berlin band.(Xaiv ib qho thiab koj yuav tau txais lub hnub qub kub.)
Tshawb xyuas lub tuam txhab lub vev xaib… zoo, cov lus qhia hauv lawv lub khw yog me ntsis tsis meej, tab sis lawv yuav muag koj 5 phaus rau $ 75.00.Yog li cia peb saib github.Tsis txhob.Tsis muaj BOM nyob ntawd.
Peb muaj qhov qhib qhov hluav taws xob tsim hluav taws xob uas tuaj yeem qhia koj tias yuav tsim nws li cas es tsis txhob sau nws li cas.Kuv hu qhov no qhov chaw uas cov ntaub ntawv tseem ceeb ploj lawm.Nws zoo li tus cwj pwm tsa pob muag… nws ntxim nyiam.
OxiKit tau hais hauv kev tawm tswv yim ntawm ib qho ntawm lawv cov yeeb yaj kiab (qhov kuv txuas rau hauv zaj dab neeg, uas yog IIRC) tias qhov no yog sodium zeolite.
Ib yam li lwm yam molecular sieve, koj qhia rau cov chaw tsim khoom seb koj xav siv nws li cas, tsis yog rau dab tsi.Vim lawv yog tib yam, tab sis lub aperture txawv.
O2 concentrators feem ntau siv 13X zeolite 0.4 mm-0.8 mm los yog JLOX 101 zeolite, qhov thib ob yog kim tshaj plaws.Thaum rov tsim kho lub craigslist o2 concentrator, kuv siv 13X.Lub teeb ntsuab ib txwm nyob, yog li qhov purity ntawm o2 yog tsawg kawg yog 94%.

5A (5 angstrom) molecular sieves kuj tseem siv tau.Kuv xav tias nws tsis tshua xaiv rau nitrogen, tab sis nws tseem tuaj yeem siv tau.
Muaj cov animation zoo ntawm Wikipedia uas tuaj yeem pab koj nkag siab cov ntsiab lus ua haujlwm ntawm lub cuab yeej: https://upload.wikimedia.org/wikipedia/commons/7/76/Pressure_swing_adsorption_principle.svg Kuv compressed cua input A adsorption O oxygen Output D desorption E tso pa tawm
Thaum lub zeolite kem yuav luag tag nrho cov nitrogen, tag nrho cov li qub tau tig los tso cov nitrogen adsorbed los ntawm kem.
Ua tsaug ntau rau koj cov lus piav qhia luv luv.Kuv ib txwm xav tsis thoob yog tias lub tshuab hluav taws xob nitrogen tuaj yeem siv rau DIY tej yaam num ntawm nitrogen vuam hauv tsev.Yog li ntawd, cov khoom pov tseg ntawm cov pa oxygen concentrator yog qhov pib nitrogen: zoo meej, Kuv yuav siv nws hauv kuv qhov chaw nres tsheb tsis muaj hlau lead.
Tseeb, rau amateurs, nws yog ib qho tseem ceeb heev uas yuav tsum tau hloov huab cua mus rau hauv feem ntau ntshiab oxygen thiab feem ntau ntshiab nitrogen.Kuv xav paub yog tias koj tuaj yeem siv "feem ntau nitrogen" ua cov roj tiv thaiv rau vuam.
Rau TIG (tseem hu ua GTAW), txij li thaum lub plasma plume rhiab heev, kuv tsis paub meej.Argon roj feem ntau yog siv, qee zaum nrog me ntsis roj helium nkag mus rau hauv cov ntaub ntawv xws li txhuas thiab titanium.Cov dej ntws yog li 6 mus rau 8l / min, uas yuav loj dhau rau tus qauv compressor.
Rau vuam, nws yuav tsum yog tias qhov chaw nres tsheb loj welding hom tag nrho muag cov roj nitrogen tiv thaiv rau rohs ntau lawm, tab sis tus nqi ntawm cov khoom siv yog nruab nrab ntawm 1-2k euros.Lawv tus nqi ntws yog li 1l / ​​min, uas yog qhov tsim nyog rau molecular sieves.Yog li cia peb sib sau ua ke qee yam khoom siv thiab ua cov khoom siv tsis muaj hlau lead-dawb nyob hauv tsev!
Welders xav kom muaj peev xwm siv cov nitrogen ntshiab raws li cov pa tiv thaiv.Nws yog pheej yig dua argon lossis pheej yig dua helium.Hmoov tsis zoo, nws yog txaus reactive ntawm qhov kub thiab txias mus txog ntawm lub arc thiab nyhav tsim undesirable nitrides nyob rau hauv lub weld.
Nws yog siv rau vuam shielding roj, tab sis tsuas yog ib qho me me tuaj yeem hloov cov yam ntxwv ntawm cov vuam.
Obviously, nws muaj peev xwm siv nws nyob rau hauv laser vuam, tab sis txawm ib tug zoo-tsim fab tej zaum yuav tsis muaj no functionality.
Yog li, hauv txoj kev xav, tsawg kawg ib PSA tuaj yeem siv los txo cov nitrogen, thiab tom qab ntawd lwm PSA (siv lwm zeolite) kom txo cov pa oxygen, tawm hauv cov concentration ntau dua uas tsis yog oxygen lossis nitrogen.
Thaum koj hais yog lawm, ntawm lub sijhawm ntawd, kuv xav kom koj condense cua thiab tom qab ntawd distil nws cais tawm cov roj uas koj xav tau / tsis xav tau.
@Foldi-A folding point nyob rau hauv cov nqe lus ntawm lub zog tawm tswv yim thiab roj tso zis.Kuv pom zoo tag nrho tias qhov ua tau zoo yuav ntau dua ntawm qhov loj dua vim tias koj tuaj yeem siv evaporation rau ua ntej txias.
Tab sis ntawm qhov me me, koj yuav muaj 1 compressor, 4 zeolite yees thiab ib pawg ntawm cov hluav taws xob siab li qub thiab cov nqi pib ntawm tus tswj pheej yig (Lub hlwb), uas kuv xav tias yuav tsawg dua.
@irox tuaj yeem ua piv txwv nrog qhov tseeb, tab sis tsis muaj leej twg siv 2 litres ntawm oxygen yuav sai sai tuag / deteriorate yam tsis tau txais oxygen.Rau kev sib piv, peb chav saib xyuas mob hnyav (ICU) cov neeg mob uas muaj qhov dej siab thib ob vim yog COVID, tau txais 45-55L thaum FIO2 yog 60-90%.Cov no yog peb cov neeg mob "ruaj khov".Yog tsis muaj dej ntws siab, lawv yeej yuav deteriorate sai sai, tab sis lawv yuav tsis mob heev uas peb yuav intubated.Koj yuav pom cov lej zoo sib xws lossis siab dua rau lwm tus neeg mob ARDS lossis feem ntau lwm yam xwm txheej uas yuav tsum tau muaj lub qhov ntswg loj dua li cov pa nasal cannula.
Rau kuv, kev siv yog niche.Qhov no tuaj yeem ua rau 2 tus neeg mob nyob rau ntawm qhov siab ntawm 6-8 L, uas yog qhov chaw uas muaj qhov dej ntws siab tshaj qhov pom ntawm qhov ntswg cannula lossis NIPPV.Kuv xav hais tias qhov no ua tau zoo heev rau lub tsev kho mob me me uas muaj cov pa oxygen tsawg, thiab tuaj yeem muab kev pabcuam kho mob rau cov neeg mob uas muaj kab mob ntev hauv lub sijhawm luv luv.
Tus neeg mob puas noj 6 litres (lossis 45-55 litres) ntawm cov pa oxygen ib feeb, lossis puas yog ib nrab poob, exhaled rau ib puag ncig lossis ib yam dab tsi?
Kuv keeb kwm yav dhau los / kev paub tsuas yog ib qho kev txhawb nqa lub neej rau cov neeg noj qab haus huv (nrog cov pa roj carbon dioxide tshem tawm thiab kwv yees li 2 litres ntawm carbon dioxide ntxiv rau ib tus neeg hauv ib feeb), yog li ua tsaug rau tus naj npawb ntawm kev siv kho mob, qhov no yog qhov qhib qhov muag!
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lawv tau txais cov pa oxygen, vim tias lawv lub ntsws mob heev thaum noj oxygen.Yog li ntawd, piv nrog cov kev xav tau ntawm tib neeg lub cev, tus nqi yog siab heev, vim hais tias qhov tseeb, tsawg tus neeg nkag.
Kuv tsis paub tias tus neeg hais lus yog tus tsim los, tiam sis qhov no tsis phim li nws piav.Molecular sieves thiab zeolites tsis cuab N2, lawv tuaj yeem ntes O2.Txhawm rau ntes N2, koj xav tau nitrogen absorber, uas yog cov tsiaj sib txawv kiag li.Lub sieve ntxiab O2 nyob rau hauv siab thaum lub nitrogen txuas ntxiv mus.Qhov no yuav tsum yog qhov tseeb, vim tias thaum koj tso lub siab thiab siv nws pov tseg N2 hauv lwm kem, nws tsis muaj kev nkag siab los sim tshem N2 nrog N2..Cov no yog lub siab viav vias adsorption units (PSA), lawv ua haujlwm los ntawm ntxiab O2.Kev siab dua thiab lub tog raj kheej loj tuaj yeem ua rau muaj kev ua haujlwm siab dua (4 lub tog raj kheej muaj qhov ua tau zoo txog li 85%).Qhov no condense O2, tab sis nws tsis ua hauj lwm raws li nws hais (los yog tsab xov xwm hais)
Koj yuav tsum muab cov ntaub ntawv thov, vim tias koj tuaj yeem nqus tau N2 ntawm 13X thiab 5A zeolite molecular sieves.http://www.phys.ufl.edu/REU/2008/reports/magee.pdf
Wikipedia PSA tsab xov xwm kuj tau lees paub tias zeolite absorbs nitrogen.https://en.wikipedia.org/wiki/Pressure_swing_adsorption#Process
"Txawm li cas los xij, nws yog pheej yig dua li chav ua lag luam."Txij li thaum BOM tshaj $ 1,000, nws nyuaj rau kuv los txhawb cov nqe lus no.Daim nqi ntawm cov ntaub ntawv rau tsev neeg (tsis yog portable) coj mus muag concentrators nqi ze rau 1/3, yog ib qho yooj yim mus nrhiav, thiab yuav tsum tsis txhob ua hauj lwm.Kuv paub 17LPM txias, tab sis tsis muaj leej twg nyob sab nraud ntawm lub tsev kho mob yuav thov kom muaj tsheb khiav zoo li no.Tus neeg twg uas muaj qhov kev thov no tab tom kuaj xyuas lossis raug intubated.
Yog, qhov no yog ib qhov project txias, tab sis yog, nws cov nqi-zoo yog negligible rau qee yam.Hauv Australia, cov khoom siv tshiab 10l/pm tsuas yog $1500AUD xwb.Piv txwv tias $ 1000 yog US las, qhov no txo ​​tus nqi ntawm kev yuav khoom tshiab.
Ua ntej muaj kev sib kis, kuv yuav ib qho ntawm eBay ntawm tus nqi ntawm ib ncig ntawm £ 160 nrog qhov ntws ntawm 1.5 litres ib feeb ntawm tus nqi ntawm 98%.Thiab qhov no yog ntau ntsiag to dua qhov no!Ua li no, koj tuaj yeem tsaug zog tiag tiag.
Tab sis tau hais tias, qhov no yog kev siv zog loj heev.Muab tso rau hauv chav nyob ib sab ntawm cov yeeb nkab ntev kom tsis txhob muaj suab nrov thiab tawg phom sij…
Kuv xav paub seb nws puas tuaj yeem siv tau los ua qhov yuav luag cov nitrogen ntshiab, hauv kev tiv thaiv ib puag ncig lossis txawm nyob hauv vuam?
Yuav ua li cas txog cov log tsheb uas muaj nitrogen.Xav txog cov nqi lawv them rau qhov kev pabcuam no, nitrogen yuav tsum kim heev…
Cov kauj ruam tom ntej yuav yog qhov nthuav-tau txais cov txiaj ntsig ntawm qhov kev xav no thiab cais 95% O2 + 5% Ar sib tov.Qhov no tuaj yeem ua tiav los ntawm kev sib cais kinetic siv CMS molecular sieve hauv PSA system.Tom qab ntawd teeb tsa lub twj tso kua mis 150 bar los sau lub tog raj kheej argon.
Tam sim no, peb tsuas yog xav tau ib tus neeg los ua cov txheej txheem Linde hauv tsev kom muaj kev lom zem tiag tiag
Los ntawm kev siv peb lub vev xaib thiab cov kev pabcuam, koj pom zoo meej rau peb qhov kev tso kawm ntawm kev ua tau zoo, kev ua haujlwm thiab kev tshaj tawm cov ncuav qab zib.Kawm ntxiv
