Ukusho ukuthi ziningi izinto ezenzekile onyakeni selokhu kwaqala ubhubhane lwe-COVID-19, lokhu kuwukubukelwa phansi kwezehlakalo ezimangalisayo, kangangokuthi kunzima ukukhumbula izinsuku zokuqala zomphakathi we-hardware hacker owawusebenzisa inqwaba. -kukhiqizwe ukusabela kwe-PPE., I-ventilator eyenziwe ekhaya njalonjalo.Kodwa-ke, asikhumbuli ukuthi kube nemizamo eminingi kakhulu yokwakha le-DIY oxygen concentrator ngesikhathi sesigaba sokuqala sokunwetshwa.
Uma kubhekwa ubulula nokusebenza komklamo obizwa nge-OxiKit, kubonakala kuxakile ukuthi asikaziboni ezinye izisetshenziswa ezinjalo.I-OxiKit isebenzisa i-zeolite, iminerali enezimbotshana engasetshenziswa njengesisefo samangqamuzana.Ubuhlalu obuncane bupakishwa kusilinda esenziwe ngamapayipi e-PVC kanye nezixhumi ezivela esitolo sezingxenyekazi zensimbi, futhi zixhunywe ku-compressor yomoya engenawo uwoyela ngevalvu yomoya elawulwa yinani lamavalvu e-solenoid.Ngemva kokupholisa kukhoyili yeshubhu yethusi, umoya ocindezelweyo uyaphoqeleka ukuba udlule kukholamu ye-zeolite egcina ngokukhetha i-nitrogen kuyilapho ivumela umoya-mpilo ukuba udlule.Umfudlana komoyampilo uyahlukaniswa, ingxenye eyodwa ingena ethangini le-buffer, futhi enye ingxenye ingena ekuphumeni kombhoshongo wesibili we-zeolite, lapho kukhishwa khona i-nitrogen ekhangiswe ngenkani.I-Arduino ilawula i-valve ukuthi igeleze igesi ngokushintshana iye phambili naphambili ukuze ikhiqize amalitha angu-15 ka-96% oksijini ohlanzekile ngomzuzu.
I-OxiKit ayithuthukisiwe njengamajeneretha omoya wokuhweba, ngakho-ke ayithuli kakhulu.Kodwa lokhu ishibhile kuneyunithi yezohwebo, futhi kubaduni abaningi, kulula ukwakha.Imiklamo ye-OxiKit yonke ingumthombo ovulekile, kodwa ithengisa amathuluzi amathuluzi nezinye izingxenye okunzima ukuzithenga nezinto ezidlekayo, njenge-zeolite.Sizozama ukwakha into efana nalena ngoba ubuchwepheshe busezingeni eliphezulu.Ukuba nomthombo womoya-mpilo ogeleza kakhulu akuwona umqondo omubi futhi.
15 amalitha ngomzuzu kubonakala kumangalisa kakhulu.Ngokwesilinganiso, kwanele ukusekela izimpilo zabantu abangu-7 ngaphansi kwezimo ezijwayelekile (umuntu ngamunye @ 2 amalitha ngomzuzu).
Bengilokhu ngifuna ukwazi ukuthi lezi zisebenza kanjani.Kuyathakazelisa.Kubonakala sengathi iphula imithetho ye-thermodynamics, kodwa akunjalo.
Ngenani elikhulu kangaka lomoya-mpilo okhiqizwayo, ngifuna ukwazi ukuthi kuzokwenzekani uma ulenga le ngane enjinini yemoto futhi/noma uyikhulise.Kungase kufane ne-nitrite.Lokhu kuzophepha impela, ngoba ungayisetha ukuze umoya-mpilo “ohlanzekile” okhiqizwayo udliwe ngokushesha eduze kwenjini esikhundleni sokugcinwa noma yikuphi.Nokho, ngidinga ukulungisa imoto kuqala.Uhlehlisiwe… "Kuzoba kubi."
Ngicabanga ukuthi lokhu kulungele ukushisela/ukubrazing/ukusika umoya-mpilo/i-propane, i-oxygen/i-hydrogen noma i-oxygen/acetylene.
Yebo, ngemva kokubuka le vidiyo, i-YT iveze ividiyo yesiphakamiso sika-Dalbor Farny kusixhumi se-O2.Inhloso ukuhlinzeka ngethoshi likaphethiloli we-oxygen alidingayo kumshini ophephetha ingilazi.Dala ishubhu yakho yedijithali eyenziwe ngokwezifiso.Eqinisweni, eziyisithupha zazo zihlangana ukuze zikhiqize i-30 lpm O2.
Ngicabanga ukuthi injini engu-2 litre egijima ngezinkulungwane ezimbalwa ze-RPM ingase idle injini engu-15-litre esikhundleni somzuzu ongu-1.Nokho, ingabe lokhu kungase kunyuse izinga le-oksijini emoyeni owukhiphayo libe sezingeni elanele?ngempela angazi
I-Nitrite inganikeza amandla ngoba ikhipha i-molecule ye-nitrogen ku-molecule ngayinye ebolile ye-nitrous oxide (igcina umthamo wayo njengoba kusetshenziswa umoya-mpilo), njengoba nje inyusa ukugcwala komoyampilo okusebenzayo ( Ukukhishwa kuzokhipha nokushisa).Ukumpompa umoya-mpilo ohlanzekile akuzuzisi kangako, ngoba usalahlekelwa umthamo futhi kufanele ubhekane nezinkinga ezingase zithungele isivimbo senjini.
Uzodinga ukukhuphula ngokujulile.Injini yemoto engu-2-litre enesivinini esingu-2500 rpm "iphefumula" cishe ama-cubic metres angu-2.5 womoya ngomzuzu (21% O²).Kucishe kube izikhathi ezingama-600 lapho umuntu ephumule.Umthamo wokuphefumula osetshenziswa abantu cishe u-25% we-O², kanti umthamo wokuphefumula osetshenziswa izimoto ucishe ube ngu-90%…
Iphinde ishise amapiston ashisa kakhulu futhi ancibilike.Ngokutshekisa uphethiloli oxubile, ungathola amandla engeziwe kunoma iyiphi injini.Kodwa i-piston izoncibilika ngenxa yokwanda kokushisa.Okuqukethwe komoyampilo okuphansi kuvimbela insimbi ukuthi ingancibiliki.
Izinjini zezimoto ezijwayelekile zikhawulelwe ukuhamba komoya futhi zizokhiqiza amandla amakhulu lapho zishisa wonke umoya-mpilo osemoyeni.Lokhu kufezwa ngokucebisa kancane ingxube, engashisi uphethiloli othile.Ngaphandle uma kudingeka amandla aphezulu, izinjini zezimoto ngokuvamile zisebenza ngokutshekisa kancane, ngoba ukusebenza okunothe uphethiloli kusho ukunciphisa ukonga kukaphethiloli kanye nokwanda kokungcoliswa kwe-hydrocarbon.
Uma ufuna ukusebenzisa lesi sici ukukhulisa amandla, udinga indlela yokukhohlisa ikhompuyutha yenjini ukuthi yengeze iphesenti elithile likaphethiloli ngesikhathi esifanayo.
Uma ungakwazi ukugcina isilinganiso se-air-fuel singashintshi, sicishe sifane nokuvula i-throttle ngamaphesenti ambalwa kuphela.
Kodwa-ke, uma weqa “amaphesenti ambalwa” (okungaqondakali ngamabomu…), ungase ufinyelele umkhawulo wamandla e-ECU okuqonda ukuthi kungena umoya ongakanani, noma ulawule ukuthi ungakanani uphethiloli ophumayo, noma usethe isikhathi esilungile sokubasa kungakhathaliseki ukuthi yisiphi isivinini. nokugeleza komoya owusebenzisayo.
Izinga lokugeleza elidingekayo ukuze kugcinwe umuntu ephila lincike kakhulu esimweni sakhe!2 l/min ilula kakhulu.Iziguli eziningi ezidinga ukunakekelwa okujulile zidinga u-15 l/min.
Qaphela ukuthi uphelelwa umoya-mpilo.Ukugcwala okuphezulu komoyampilo kungenza izinto eziningi zishe futhi kukhuthaze ukuvutha okuzenzakalelayo kwamafutha kanye nezinto zokugcoba.Yingakho basebenzisa ama-compressor angenawo uwoyela.
Lokho, nezinye izindlela eziningi zokucubungula i-O2 “ezingezona enembile” zingakulimaza, ikakhulukazi ngaphansi kwengcindezi ekhulayo.
Uma udlala i-O2, ungasebenzisa i-Vance Harlow's Oxygen Hacker's Companion (abatshuzi be-nitrox kungenzeka sebenaye lo mngane): http://www.airspeedpress.com/newoxyhacker .html
Angiyazi incwadi, ngumsebenzisi, hhayi ishuna.Nokho, ngiyabonga ngereferensi yakho, ngizo-oda ikhophi ngokushesha nje lapho ifomu selisebenza!
Yebo, ngizosho.Imodi yokuhluleka yomoya ocindezelwe we-PVC ukuqhuma kwe-shrapnel, ngakho-ke bhekisisa lezi zilinganiso zokucindezela ngokucophelela-njengoba ububanzi bepayipi bukhula, isilinganiso sokucindezela sizokwehla.
Ekuqaleni kwawo-1980, ngasebenza enkampanini eqashisa ngemishini yezokwelapha eyayiqashisa futhi yanikeza isevisi amajeneretha omoya-mpilo kaDevilbiss.Ngaleso sikhathi, la mayunithi ayelingana nesiqandisi esincane sikabhiya.Ngikhumbula ngokucacile imvelo "yesitoreji sezingxenyekazi zekhompyutha" yesakhiwo sayo sangaphakathi.Ngisakhumbula ukuthi umbhede we-sieve wenziwa ngepayipi le-PVC engu-4-intshi nesembozo, ngakho-ke isakhiwo esichazwe kule phrojekthi sihambisana nobuchwepheshe bangaphambilini bomlando (kodwa ngokusobala obusebenzayo).
I-compressor iwuhlobo lwe-piston/diaphragm ene-oscillating kabili, ngakho awekho amafutha emoyeni ocindezelwe.I-valve ekhanda le-compressor ingumhlanga omncane wensimbi engagqwali.
Ukuhlelwa kokusakaza kwenziwa ngesibali sikhathi esisebenza ngomshini, ayidingeki i-Arduino.Isibali sikhathi sinokuvumelanisa (i-clock gear motor) eshayela shaft enamasondo ekhamera amaningi.Iswishi encane egibele ikhamera ishisa i-valve ye-solenoid, ibangele ukuthi igesi ihambe.
Isitha esikhulu sale mishini umswakama ophezulu.I-adsorption yama-molecule amanzi ibhubhisa umbhede we-sieve.
Ngaphambi nje kokuba ngishiye inkampani, saqala ukuthola i-concentrator kumncintiswano we-Devilbiss (igama manje alaziwa kimi), futhi inkampani ibonise intuthuko enkulu.Ngaphezu kwe-concentrator entsha encane nethule, inkampani iphinde yakha umbhede wesisefo isebenzisa amashubhu e-aluminium.Ishubhu limbozwe ngepuleti elinemifantu eyenziwe ngomshini yama-O-rings.Kubonakala sengathi ngicabanga ngokusekela okunezintambo ezigcwele okuhlanganisa imihlangano.Inzuzo yalo mklamo yukuthi uma kunesidingo, umbhede ungahlukaniswa futhi impahla ye-sieve ingashintshwa.Baphinde basusa izibali sikhathi ezisebenza ngomshini futhi esikhundleni sazo bafaka amadivaysi kagesi alula nama-SSR ukuze acuphe ama-solenoid.
Adinga ukusetshenziswa kwamapayipi e-SCH40 (ingcindezi elinganiselwe engu-260psi @ 3″) futhi ahlome ngokusobala ngevalvu yokuphepha engu-40psi kanye nesilawuli esingu-20-30psi ngaphambi kokuba i-PVC icindezeleke, ngakho-ke kunesici esihle sokuphepha.Angiqiniseki ukuthi izovezwa kanjani ku-O2 Shintsha ukuqina.
Ukucindezela kokuqhuma kwe-SCH40 izikhathi eziningi ukucindezela okulinganiselwe-kuya ngobubanzi.Ipayipi elingu-3-intshi lilinganiselwa ku-850 psi, kanti ipayipi elingu-6 intshi lilinganiselwa ku-500 psi.I-1/2 intshi isondele ku-2000 psi.Phinda kabili inombolo ye-SCH80.Yingakho iziqhumane zethenisi ze-PVC zingaqhumi-ziningi kakhulu.Ukuwakhulisela egumbini elivuthayo elingu-6 noma 8 kuzokwandisa inhlanhla yakho.Kodwa ngokuvamile, umphakathi wama-hacker uvame ukubukela phansi amandla ezinqwaba zepulasitiki.https://www.pvcfittingsonline.com/resource-center/strength-of-pvc-pipe-with-strength-chart/
Ngingaba nentshisekelo yokunciphisa ikhono le-ateur lokusebenzisa iziqhumane (futhi mhlawumbe nobumsulwa).Imakethe yokuzilibazisa ivamise ukuthenga amasilinda omoya mpilo asethathe umhlalaphansi.Lowo kwakuwumbono wami wokuqala, kodwa izindleko zekhithi + BOM zayidlula kude inani leyunithi yezokwelapha ethathe umhlalaphansi.
Injini yemoto engamalitha angu-2 ingadla amalitha angu-9,000/ngomzuzu womoya-mpilo (isivinini esikhulu), ngakho-ke amalitha angu-15/umzuzu womoya-mpilo angaba mfishane izikhathi ezingu-600., Lena idivayisi epholile.Ngithenge ama-concentrator amaningi avuselelwe kabusha angu-5 amalitha ngomzuzu nge-$ 300 ngayinye (intengo ibonakala ikhuphuka).Ikhiqiza amalitha ama-5 ngomzuzu.Kusetshenziswa ama-watts angamakhulu ambalwa, ngakho-ke kukhishwa ukuthi amalitha angu-9000 ngomzuzu (ngokwezinjongo zokuzijabulisa kuphela) adinga cishe u-360 kW (480 hp).
Ngoba i-algorithm yabo yabhalwa ibhendi yaseBerlin.(Bala eyodwa futhi uzothola inkanyezi esagolide.)
Bheka iwebhusayithi yenkampani… kahle, imininingwane esitolo sabo ayicacile, kepha bazokuthengisa opondo aba-5 ngo-$75.00.Ngakho-ke ake sibheke i-github.Ungenzi.Ayikho iBOM lapho.
Sinomklamo ovulekile we-electromechanical ongakutshela ukuthi uwakha kanjani esikhundleni sokuthi uwugcwalisa kanjani.Ngibiza le ndawo ngendawo lapho ulwazi olubalulekile lungekho khona.Kufana nomlingiswa ophakamisa amashiya… kuyathakazelisa.
U-OxiKit ushilo ekuphawuleni kweyodwa yamavidiyo wabo (leyo engiyixhume endabeni, okuyi-IIRC) ukuthi lena yi-sodium zeolite.
Njenganoma yisiphi esinye isisefo se-molecular, utshela umenzi ukuthi ufuna ukuyisebenzisela ini, hhayi ukuthi isenzela ini.Ngoba ziyinto efanayo, kodwa imbobo yehlukile.
I-O2 concentrators ivamise ukusebenzisa i-13X zeolite 0.4 mm-0.8 mm noma i-JLOX 101 zeolite, eyesibili iyona ebiza kakhulu.Lapho ngakha kabusha i-craigslist o2 concentrator, ngisebenzise i-13X.Ukukhanya okuluhlaza kuhlale kuvuliwe, ngakho-ke ubumsulwa be-o2 okungenani bungama-94%.

5A (5 angstrom) izisefo zamamolekyuli nazo zingasetshenziswa.Ngicabanga ukuthi ayikhethi kakhulu i-nitrogen, kodwa isengasetshenziswa.
Kukhona ukugqwayiza okuhle ku-Wikipedia okungakusiza ngokunembile ukuthi uqonde umgomo wokusebenza wedivayisi: https://upload.wikimedia.org/wikipedia/commons/7/76/Pressure_swing_adsorption_principle.svg Ngicindezele okokufaka komoya I-adsorption O Okukhipha umoya-mpilo D desorption Exhaust
Uma ikholomu ye-zeolite cishe igcwele i-nitrogen, wonke ama-valve ayaphendulwa ukuze akhulule i-nitrogen ekhangiswe yikholomu.
Ngiyabonga kakhulu ngencazelo yakho emfushane.Bengihlala ngizibuza ukuthi ingabe ijeneretha ye-nitrogen ingasetshenziselwa amaphrojekthi we-DIY we-nitrogen welding ekhaya.Ngakho-ke, ukukhishwa kwemfucuza kwe-concentrator komoya-mpilo ngokuyisisekelo kuyi-nitrogen: iphelele, ngizoyisebenzisa esiteshini sami sokunamathisela esingenamthofu.
Ngempela, kubantu abangafundile, kuwusizo kakhulu ukukwazi ukuguqula umoya ube umoya-mpilo ohlanzekile kakhulu futhi ikakhulukazi i-nitrogen emsulwa.Ngifuna ukwazi ukuthi ungasebenzisa “i-nitrogen ikakhulukazi” njengegesi evikela ukushisela.
Ku-TIG (eyaziwa nangokuthi i-GTAW), njengoba i-plasma plume izwela kakhulu, angiqiniseki.I-Argon gas isetshenziswa kakhulu, ngezinye izikhathi ngegesi encane ye-helium ukuze ingene ezintweni ezifana ne-aluminium ne-titanium.Ukugeleza cishe ku-6 kuya ku-8l/min, okungenzeka kube kukhulu kakhulu ku-compressor evamile.
Ngokushisela, kufanele kube ukuthi amabhrendi esiteshi sokushisela wonke athengisa igesi yokuvikela i-nitrogen ukuze kukhiqizwe ama-rohs, kodwa intengo yekhithi iphakathi kwama-euro angu-1-2k.Izinga lokugeleza kwawo licishe libe ngu-1l/​min, elifaneleka kakhulu izisefo zamangqamuzana.Ngakho-ke ake sihlanganise izingxenyekazi zekhompiyutha futhi senze i-solder engenamthofu ekhaya!
Abashiseli bafuna ukwazi ukusebenzisa i-nitrogen ehlanzekile njengegesi evikelayo.Kushibhile kune-argon noma i-helium eshibhile.Ngeshwa, isabela ngokwanele ezingeni lokushisa elifinyelelwe yi-arc futhi ijwayele ukwakha ama-nitrides angathandeki ekushiseleni.
Isetshenziselwa igesi yokuvikela i-welding, kodwa inani elincane kuphela elingashintsha izici ze-weld.
Ngokusobala, kungenzeka ukuyisebenzisela i-laser welding, kodwa ngisho nendwangu ehlomele kahle ingase ingabi nalo msebenzi.
Ngakho-ke, ngombono, okungenani i-PSA eyodwa ingasetshenziswa ukunciphisa i-nitrogen, bese enye i-PSA (isebenzisa enye i-zeolite) ukunciphisa umoya-mpilo, okushiya ukuhlushwa okuphezulu kwezinto ezingezona i-oxygen noma i-nitrogen.
Uma uqinisile, ngaleso sikhathi, ngiphakamisa ukuthi unciphise umoya bese uwuhlakaza ukuze uhlukanise igesi oyifunayo/ongayifuni.
@Foldi-Iphoyinti eligoqayo ngokokufaka kwamandla kanye nokuphuma kwegesi.Ngiyavuma ngokuphelele ukuthi ukusebenza kahle kuzoba phezulu kakhulu esikalini esikhulu ngoba ungasebenzisa ukuhwamuka ukuze upholise ngaphambili.
Kodwa ngesilinganiso esincane kakhulu, uzoba ne-compressor engu-1, imibhoshongo ye-zeolite engu-4 kanye nenqwaba yama-valve okucindezela kagesi kanye nezindleko zokuqala zesilawuli esishibhile (I-Brain), engicabanga ukuthi izoba ngaphansi.
@irox angakwazi ngokufanisa ngokuqiniseka, kodwa akekho osebenzisa amalitha angu-2 omoya-mpilo ozofa ngokushesha/awohloke ngaphandle kokuthola umoya-mpilo.Uma kuqhathaniswa, iziguli zethu zeyunithi yethu yokunakekela kakhulu (ICU) ezinokugeleza okuphezulu kwesibili ngenxa ye-COVID, zithola u-45-55L lapho i-FIO2 ingama-60-90%.Lezi yiziguli zethu "ezizinzile".Uma kungekho ukugeleza okuphezulu, nakanjani zizowohloka ngokushesha, kodwa ngeke zigule kangangokuthi sizofakwa intuba.Uzobona izinombolo ezifanayo noma eziphakeme kwezinye iziguli ze-ARDS noma ezinye izimo eziningi ezidinga i-cannula yamakhala enkulu kune-cannula yamakhala evamile.
Kimi, ukusetshenziswa kuyi-niche.Lokhu kungagcina ngokufanelekile iziguli ezi-2 ekucindezelweni kwe-6-8 L, empeleni okuyindawo lapho ukugeleza okuphezulu kufakwe imisebe ngaphezu kwe-cannula yamakhala evamile noma i-NIPPV.Ngingathanda ukusho ukuthi lokhu kuphumelela kakhulu esibhedlela esincane esinokunikezwa kwe-oksijeni okulinganiselwe, futhi singahlinzeka ngezinsizakalo zezokwelapha ezigulini ezinezifo ezingapheli ezimweni eziphuthumayo zesikhashana.
Ingabe isiguli sisebenzisa amalitha angu-6 (noma ama-45-55) omoya-mpilo ngomzuzu, noma ingabe ingxenye yawo ilahlekile, ikhishelwa endaweni ezungezile noma okuthile?
Isizinda sami/isipiliyoni sami siwuhlelo olulinganiselwe lokusekela ukuphila kwabantu abanempilo (kususwe i-carbon dioxide futhi cishe amalitha angu-2 e-carbon dioxide engezwe ngomuntu ngamunye ngomzuzu), ngakho ngenxa yenani lokusetshenziswa kwezokwelapha, lokhu kuvula amehlo!
Kubalulekile ukukhumbula ukuthi bathatha umoya-mpilo, ngoba amaphaphu abo aminyene kakhulu lapho bethatha umoya-mpilo.Ngakho-ke, uma kuqhathaniswa nezidingo zethiyori zomzimba womuntu, izindleko ziphezulu kakhulu, ngoba empeleni, bambalwa kakhulu abantu abangena.
Angazi noma umuntu okhulumayo uyena owayiklama, kodwa lokhu akuhambisani nendlela ayichaza ngayo.Izisefo zamangqamuzana nama-zeolite awacuphi i-N2, angacupha i-O2.Ukuze ubambe i-N2, udinga i-nitrogen absorber, okuyisilwane esihluke ngokuphelele.Isisefo sivalela i-O2 ngaphansi kwengcindezi kuyilapho i-nitrogen iqhubeka nokudlula.Lokhu kufanele kube yiqiniso, ngoba uma ukhulula ukucindezela futhi uyisebenzisela ukulahla i-N2 kwenye ikholomu, akuwenzi umqondo ukuzama ukususa i-N2 nge-N2..Lawa amayunithi e-press swing adsorption units (PSA), asebenza ngokucupha i-O2.Ukucindezela okuphezulu namasilinda amakhulu kungaletha ukusebenza kahle okuphezulu (amasilinda ama-4 anokusebenza kahle okungafika ku-85%).Lokhu kuyayinciphisa i-O2, kepha ayisebenzi njengoba esho (noma indatshana isho)
Kufanele unikeze umthombo wolwazi oceliwe, ngoba ungakwazi ukukhangisa i-N2 ngokuphelele ku-13X kanye nezisefo ze-molecular zeolite ze-5A.http://www.phys.ufl.edu/REU/2008/reports/magee.pdf
I-athikili ye-Wikipedia PSA iphinde iqinisekise ukuthi i-zeolite imunca i-nitrogen.https://en.wikipedia.org/wiki/Pressure_swing_adsorption#Process
"Kodwa-ke, ishibhile kuneyunithi yezohwebo."Njengoba i-BOM idlula i-$ 1,000, kunzima kimi ukusekela lesi sitatimende.Ibhili lezinto zokwakha zasendlini (okungaphatheki) libiza cishe ku-1/3, litholakala kalula, futhi alidingi msebenzi.Ngiyazi ukuthi i-17LPM ipholile, kodwa akekho ongaphandle kwesibhedlela ozocela ithrafikhi enjalo.Noma ubani onesicelo esinjalo usezobheka noma afakwe intuba.
Yebo, lena iphrojekthi epholile, kodwa yebo, ukuphumelela kwayo kwezindleko akunakwa ngokwezinga elithile.E-Australia, imishini emisha engu-10l/pm ilinganiselwa ku-$1500AUD kuphela.Uma sicabanga ukuthi i-$1000 ngamadola aseMelika, lokhu kunciphisa izindleko zokuthenga imishini emisha.
Ngaphambi kwalolu bhubhane, ngathenga eyodwa ku-eBay ngentengo ecishe ibe ngu-£160 ngokugeleza kwamalitha ayi-1.5 ngomzuzu ngentengo engama-98%.Futhi le nto ithule kakhulu kunalena!Ngale ndlela, ungakwazi ukulala ngempela.
Kodwa sengikushilo lokho, lokhu kuwumzamo omkhulu.Yibeke ekamelweni eduze kwepayipi elide ukuze ugweme umsindo nobungozi bokuqhuma...
Ngifuna ukwazi ukuthi kungenzeka yini ukuthi uwusebenzise njengomthombo we-nitrogen ocishe umsulwa, ezindaweni ezivikelayo noma ngisho nasekushiseleni?
Kuthiwani ngamathayi agcwele initrogen.Uma kucatshangelwa izinkokhelo abazikhokhisa le sevisi, i-nitrogen kumele ibize kakhulu...
Isinyathelo esilandelayo singase sithakazelise-thola okukhiphayo kwalesi sigxili futhi uhlukanise ingxube ye-Ar engu-95% O2 + 5%.Lokhu kungenziwa ngokuhlukaniswa kwe-kinetic kusetshenziswa isisefo semolekyuli ye-CMS ohlelweni lwe-PSA.Bese usetha iphampu yebha engu-150 ukugcwalisa isilinda se-argon.
Manje, sidinga kuphela umuntu ozokwenza inqubo ye-Linde ekhaya ukuze sibe nobumnandi bangempela obuqhumayo
