Kunena kuti zinthu zambiri zachitika chaka chino kuyambira pomwe mliri wa COVID-19 unayamba, izi sizikutanthauza zochitika zazikulu, kotero kuti n'zovuta kukumbukira masiku oyambirira a gulu la anthu owononga zida omwe adagwiritsa ntchito njira yopangira zinthu zambiri, makina opumira opangidwa kunyumba ndi zina zotero. Komabe, sitikukumbukira kuti panali zoyesayesa zambiri zomanga chosungira mpweya cha DIY panthawi yoyamba kukula.
Popeza kapangidwe kake kotchedwa OxiKit ndi kosavuta komanso kogwira mtima, zikuwoneka zachilendo kuti sitinawonepo zida zina zotere. OxiKit imagwiritsa ntchito zeolite, mchere woboola womwe ungagwiritsidwe ntchito ngati sefa ya molekyulu. Timikanda tating'onoting'ono timayikidwa mu silinda yopangidwa ndi mapaipi a PVC ndi zolumikizira kuchokera ku sitolo yosungiramo zida, ndikulumikizidwa ku compressor ya mpweya wopanda mafuta kudzera mu valavu yoyendetsedwa ndi ma solenoid valve angapo. Pambuyo pozizira mu coil ya chubu cha mkuwa, mpweya wopanikizika umakakamizika kudutsa mu mzere wa zeolite womwe umasunga nayitrogeni pomwe mpweya umadutsa. Mtsinje wa okosijeni umagawika, gawo limodzi limalowa mu thanki ya buffer, ndipo gawo lina limalowa m'malo otulukira nsanja yachiwiri ya zeolite, komwe nayitrogeni wokakamizidwa umatulutsidwa. Arduino imalamulira valavu kuti iyendetse mpweya mosinthana kuti ipange malita 15 a 96% oxygen yoyera pamphindi.
OxiKit siili bwino ngati majenereta a okosijeni amalonda, kotero siili chete kwenikweni. Koma iyi ndi yotsika mtengo kwambiri kuposa chipangizo chamalonda, ndipo kwa anthu ambiri obera, ndi yosavuta kupanga. Mapangidwe a OxiKit onse ndi otseguka, koma amagulitsa zida ndi zida zina zovuta kupeza ndi zinthu zina zogwiritsidwa ntchito, monga zeolite. Tidzayesa kupanga chinthu chonga ichi chifukwa ukadaulo wake ndi wabwino kwambiri. Kukhala ndi gwero la okosijeni wambiri si lingaliro loipa.
Malita 15 pa mphindi imodzi akuoneka odabwitsa kwambiri. Ponena za kukula, ndikokwanira kuchirikiza miyoyo ya anthu 7 pazochitika zabwinobwino (munthu aliyense pa malita awiri pa mphindi imodzi).
Nthawi zonse ndimafuna kudziwa momwe izi zimagwirira ntchito. Zosangalatsa. Zikuoneka kuti zikuphwanya malamulo a thermodynamics, koma sizili choncho.
Ndi mpweya wochuluka chonchi wopangidwa, ndikufuna kudziwa zomwe zingachitike ngati mupachika mwana uyu pa injini ya galimoto ndi/kapena kumukulitsa. Zingakhale ngati nitrite. Izi zidzakhala zotetezeka, chifukwa mutha kuziyika kuti mpweya "woyera" wopangidwawo udyedwe nthawi yomweyo pafupi ndi injini m'malo mosungidwa kulikonse. Komabe, ndikufunika kusintha galimoto kaye. Zolakwika… “Zidzakhala zoipa.”
Ndikuganiza kuti izi ndi zabwino powotcherera/kudula mpweya/propane, mpweya/hayidrojeni kapena mpweya/acetylene.
Inde, nditaonera kanemayu, YT adawonetsa kanema wa Dalbor Farny wokhudza O2 concentrator. Cholinga chake ndikupereka tochi yamafuta a okosijeni yomwe amafunikira pa lathe yopumira galasi. Pangani chubu chanu cha digito chomwe mwasankha. Ndipotu, zisanu ndi chimodzi mwa izo zimaphatikizana kuti zipange 30 lpm O2.
Ndikuganiza kuti injini ya malita awiri yomwe ikuyenda pa RPM yocheperako ingadye injini ya malita 15 m'malo mwa mphindi imodzi. Komabe, kodi izi zingawonjezere kuchuluka kwa mpweya mumlengalenga wolowera kufika pamlingo wokwanira? Sindikudziwa kwenikweni.
Nitrite ingapereke mphamvu chifukwa imatulutsa molekyulu ya nayitrogeni pa molekyulu iliyonse ya nitrous oxide yomwe yawonongeka (imasunga kuchuluka kwake pamene mpweya ukugwiritsidwa ntchito), monga momwe imawonjezerera kuchuluka kwa mpweya (Kutulutsa kumaperekanso kutentha). Kupopa mpweya wabwino sikopindulitsa kwenikweni, chifukwa mumatayabe kuchuluka ndipo muyenera kuthana ndi mavuto omwe angayatse injini.
Muyenera kukulitsa kwambiri. Injini ya galimoto ya malita awiri yokhala ndi liwiro la 2500 rpm "imapuma" pafupifupi 2.5 cubic metres ya mpweya pamphindi (21% O²). Ndi pafupifupi nthawi 600 kuposa ya munthu amene akupuma. Kuchuluka kwa mpweya komwe anthu amapuma ndi pafupifupi 25% ya O², pomwe kuchuluka kwa mpweya komwe magalimoto amapuma ndi pafupifupi 90%…
Imawotchanso ma pistoni otentha kwambiri komanso osungunuka. Mukatembenuza mafuta osakanikirana, mutha kupeza mphamvu zambiri kuchokera ku injini iliyonse. Koma pistoni imasungunuka chifukwa cha kutentha kwambiri. Mpweya wochepa umalepheretsa chitsulo kusungunuka.
Ma injini a magalimoto wamba amaletsedwa ndi mpweya ndipo amapanga mphamvu zambiri akamayatsa mpweya wonse womwe uli mumlengalenga. Izi zimachitika mwa kuwonjezera pang'ono chisakanizocho, chomwe sichimawotcha mafuta ena. Pokhapokha ngati mphamvu zambiri zikufunika, injini zamagalimoto nthawi zambiri zimayenda pang'onopang'ono, chifukwa kugwiritsa ntchito mafuta ambiri kumatanthauza kuchepetsa mafuta komanso kuipitsa mpweya wa hydrocarbon.
Ngati mukufuna kugwiritsa ntchito izi kuti muwonjezere mphamvu, muyenera njira yonyenga kompyuta ya injini kuti iwonjezere mafuta enaake nthawi imodzi.
Ngati mungathe kusunga chiŵerengero cha mpweya ndi mafuta nthawi zonse, chimakhala chofanana ndi kutsegula throttle ndi peresenti yochepa chabe.
Komabe, ngati mupitirira "peresenti yochepa" (mwadala kusamveka bwino ...), mutha kufikira malire a mphamvu ya ECU yomvetsetsa kuchuluka kwa mpweya wolowa, kapena kuwongolera kuchuluka kwa mafuta otuluka, kapena kukhazikitsa nthawi yoyenera yoyatsira mosasamala kanthu za liwiro ndi kayendedwe ka mpweya komwe mukugwiritsa ntchito.
Kuchuluka kwa madzi omwe amafunikira kuti munthu akhale ndi moyo kumadalira kwambiri momwe alili! 2 l/mphindi ndi kosavuta. Odwala ambiri omwe amafunikira chithandizo chamankhwala champhamvu amafunika 15 l/mphindi.
Ingosamalani kuti mpweya utha. Mpweya wambiri ungapangitse zinthu zambiri kuyaka ndikulimbikitsa kuyaka kwa mafuta ndi mafuta ambiri. Ichi ndichifukwa chake amagwiritsa ntchito ma compressor opanda mafuta.
Zimenezo, ndi njira zina zambiri "zosamveka bwino" zopangira O2 zingakupwetekeni, makamaka mukapanikizika kwambiri.
Ngati mukusewera O2, mutha kugwiritsa ntchito Vance Harlow's Oxygen Hacker's Companion (osambira a nitrox angakhale kale ndi mnzake uyu): http://www.airspeedpress.com/newoxyhacker .html
Sindikudziwa bukuli, ndi wogwiritsa ntchito, osati chosinthira. Komabe, zikomo chifukwa cha malangizo anu, ndiyitanitsa bukuli fomu ikangoyamba kugwira ntchito!
Inde, nditchula. Kulephera kwa mpweya wopanikizika wa PVC ndi kuphulika kwa shrapnel, choncho yang'anirani mosamala kuchuluka kwa kuthamanga kwa mpweya - pamene kukula kwa chitoliro kukukwera, kuchuluka kwa kuthamanga kwa mpweya kudzachepa.
Kumayambiriro kwa zaka za m'ma 1980, ndinkagwira ntchito ku kampani yobwereketsa zida zachipatala yomwe inkabwereka ndikukonza makina opangira mpweya wa Devilbiss. Panthawiyo, mayunitsi awa anali kukula kwa firiji yaying'ono ya mowa. Ndikukumbukira bwino momwe kapangidwe kake kamkati kankakhalira "kosungiramo zinthu". Ndikukumbukirabe kuti bedi la sefa linapangidwa ndi chitoliro cha PVC cha mainchesi 4 ndi chivundikiro, kotero kapangidwe kamene kafotokozedwa mu polojekitiyi kakugwirizana ndi ukadaulo wakale wakale (koma womveka bwino).
Chokometserachi ndi cha mtundu wa piston/diaphragm yozungulira kawiri, kotero mulibe mafuta mu mpweya wopanikizika. Valavu yomwe ili pamutu wa chokometserachi ndi bango lopyapyala lachitsulo chosapanga dzimbiri.
Kusankha mitsinje kumachitika pogwiritsa ntchito makina owerengera nthawi, palibe Arduino yomwe imafunika. Chowerengera nthawi chili ndi cholumikizira (mota ya giya la wotchi) chomwe chimayendetsa shaft yokhala ndi mawilo angapo a cam. Chosinthira chaching'ono chomwe chikuyenda pa cam chimayatsa valavu ya solenoid, zomwe zimapangitsa kuti mpweya uziyenda mozungulira.
Mdani wamkulu wa makina awa ndi chinyezi chambiri. Kulowetsedwa kwa mamolekyu a madzi kumawononga bedi la sefa.
Ndisanachoke pakampaniyi, tinayamba kugula chosungiramo zinthu kuchokera kwa mpikisano wa Devilbiss (dzina lake tsopano sindikulidziwa), ndipo kampaniyo yawonetsa kupita patsogolo kwakukulu. Kuwonjezera pa chosungiramo zinthu chatsopano chaching'ono komanso chopanda phokoso, kampaniyo inapanganso bedi la sieve pogwiritsa ntchito machubu a aluminiyamu. Chubucho chili ndi mbale yokhala ndi mipata yopangidwa ndi makina a O-rings. Zikuwoneka kuti ndikuganiza za chithandizo chathunthu chomwe chimaphatikiza ma assemblies. Ubwino wa kapangidwe kameneka ndikuti ngati pakufunika, bedi limatha kulekanitsidwa ndipo zinthu za sieve zitha kusinthidwa. Anachotsanso ma timer amakina ndikuzisintha ndi zida zamagetsi zosavuta komanso ma SSR kuti ayambe kugwiritsa ntchito ma solenoids.
Amafunika kugwiritsa ntchito mapaipi a SCH40 (kupanikizika kwa 260psi @ 3″) ndipo ali ndi valavu yotetezera ya 40psi ndi chowongolera cha 20-30psi PVC isanayambe kupanikizika, kotero pali chitetezo chabwino. Sindikudziwa momwe idzawonekera ku O2 Sinthani mphamvu.
Kuthamanga kwa SCH40 kumakhala kochulukira kambiri kuposa kuthamanga komwe kumayesedwa - kutengera kukula kwake. Chitoliro cha mainchesi atatu ndi pafupifupi 850 psi, ndipo chitoliro cha mainchesi 6 ndi pafupifupi 500 psi. 1/2 inchi ndi pafupifupi 2000 psi. Kuchulukitsa kawiri chiwerengero cha SCH80. Ichi ndichifukwa chake zoyatsira tenisi za PVC sizimaphulika - zambiri. Kuzikulitsa kukhala chipinda choyaka cha mainchesi 6 kapena 8 kudzawonjezera mwayi wanu. Koma kawirikawiri, gulu la anthu obera nthawi zambiri limachepetsa kwambiri mphamvu ya milu ya pulasitiki. https://www.pvcfittingsonline.com/resource-center/strength-of-pvc-pipe-with-strength-chart/
Ndingakonde kuchepetsa luso la munthu wosaphunzira kugwiritsa ntchito zozimitsa moto (ndipo mwina kuyera). Msika wa zozimitsa nthawi zambiri umagula masilinda a okosijeni achipatala opuma pantchito. Limenelo linali lingaliro langa loyamba, koma mtengo wa zida + BOM unali woposa mtengo wa chipinda chozimitsa moto chopuma pantchito.
Injini ya galimoto ya malita awiri imatha kugwiritsa ntchito mpweya wokwana malita 9,000 pa mphindi (liwiro lalikulu), kotero mpweya wokwana malita 15 pa mphindi ndi wocheperako nthawi 600. , Ichi ndi chipangizo chabwino kwambiri. Ndagula ma concentrator angapo okonzedwanso a malita 5 pa mphindi imodzi pa $300 iliyonse (mtengo wake ukuoneka kuti ukukwera). Imapanga malita 5 pa mphindi. Ma watts mazana angapo amagwiritsidwa ntchito, kotero zikuganiziridwa kuti malita 9000 pa mphindi imodzi (pongofuna zosangalatsa zokha) amafunika pafupifupi 360 kW (480 hp).
Chifukwa njira yawo yolankhulirana inalembedwa ndi gulu la Berlin. (Werengani imodzi ndipo mudzapeza nyenyezi yagolide.)
Yang'anani tsamba lawebusayiti la kampaniyo… chabwino, zomwe zili mu sitolo yawo sizikumveka bwino, koma adzakugulitsani mapaundi 5 pa $75.00. Tiyeni tiwone github. Musatero. Palibe BOM pamenepo.
Tili ndi kapangidwe ka ma elekitironi kotseguka komwe kangakuuzeni momwe mungapangire m'malo modzaza. Ndimatcha malo awa kuti palibe mfundo zofunika. Zili ngati munthu akukweza nsidze ... ndizosangalatsa.
OxiKit adatchula mu ndemanga pa imodzi mwa makanema awo (omwe ndidalumikiza nawo munkhaniyi, omwe ndi IIRC) kuti iyi ndi sodium zeolite.
Monga momwe zimakhalira ndi sefa ina iliyonse ya mamolekyu, mumauza wopanga zomwe mukufuna kuigwiritsa ntchito, osati zomwe imagwiritsa ntchito. Chifukwa ndi chinthu chimodzi, koma malo otseguka ndi osiyana.
Ma concentrator a O2 nthawi zambiri amagwiritsa ntchito 13X zeolite 0.4 mm-0.8 mm kapena JLOX 101 zeolite, yachiwiri ndiyo yokwera mtengo kwambiri. Pomanganso craigslist o2 concentrator, ndinagwiritsa ntchito 13X. Kuwala kobiriwira kumakhala koyatsidwa nthawi zonse, kotero kuyera kwa o2 ndi osachepera 94%.
