Ukusebenza kwengqondo nokuqapha kwe-Dewar tank (ibhodlela)
umthamo owodwa wokugcina umoya-mpilo webhodlela le-Dewar elingu-175 l ulingana nowama-cylinders angama-28 40 l aphezulu, anciphisa kakhulu ingcindezi yezokuthutha futhi anciphise utshalomali lwenhlokodolobha.
Umsebenzi

Isakhiwo esikhulu nemisebenzi yamazolo imi kanjena:

Cyl Isilinda esingaphandle: ngaphezu kokuvikela umgqomo wangaphakathi, ibuye yenze i-vacuum interlayer nomgqomo wangaphakathi ukuvimbela ukuhlasela kokushisa ngaphandle kwebhodlela futhi kunciphise ukukhuphuka kwemvelo ketshezi lwe-cryogenic ebhodleleni;
Cyl Isilinda sangaphakathi
③ I-Vaporizer: ngokushintshanisa ukushisa nodonga lwangaphakathi lomgqomo wangaphandle, igesi eluketshezi elisebhodleleni lingaguqulwa libe yisimo segesi;
Valve I-valve yamanzi: lawula ibhodlela le-Dewar ukugcwalisa noma ukukhipha uketshezi ebhodleleni;
Valve I-valve yokuphepha: lapho ingcindezi yomkhumbi ingaphezu kwengcindezi yokusebenza ephezulu, ingcindezi izokhishwa ngokuzenzekelayo, futhi ingcindezi yokusuka ingaphezulu kancane kwengcindezi yokusebenza enkulu;
Valve I-valve yokukhipha: lapho ibhodlela likaDewar ligcwele uketshezi, le valve isetshenziselwa ukukhipha igesi esikhaleni sesigaba sebhasi ebhodleleni, ukunciphisa ingcindezi ebhodleleni, ukugcwalisa uketshezi ngokushesha nangokushelela.

Omunye umsebenzi ukuthi lapho ingcindezi ebhodleleni likaDewar yeqa ingcindezi yokusebenza ephezulu ngesikhathi sokugcina noma ezinye izimo, i-valve ingasetshenziselwa ukukhipha ngesandla igesi ebhodleleni ukunciphisa ingcindezi ebhodleleni;

Ga Ingcindezi yokulinganisa: okukhombisa ingcindezi yesilinda sangaphakathi sebhodlela;
Valve I-valve yokulekelela: ngemuva kokuvulwa kwe-valve, uketshezi olusebhodleleni luzoshintshanisa ukushisa nodonga lwangaphandle lwesilinda ngokusebenzisa ikhoyili eshaja kakhulu, ivuthise igesi, bese ifaka isikhala sesigaba segesi engxenyeni engenhla yodonga lwangaphakathi lwesilinda, ukuze ukusungula ingcindezi ethile yokushayela (ingcindezi yangaphakathi) yesilinda, ukuze ushayele uketshezi olunamazinga aphansi okushisa ebhodleleni;
Valve Sebenzisa i-valve: isetshenziselwa ukuvula isiteshi sepayipi phakathi kwesekethe le-Dewar liquid vaporization circuit kanye ne-user gas inlet end, futhi ingasetshenziswa ukulawula izinga lokugeleza kwegesi;
Level Liquid level gauge: ingakhombisa ngqo izinga loketshezi esitsheni, futhi indawo yokufaka kufanele ilungele opharetha ukuyibuka nokulungisa.

Ukwakha

Ngokwezici zesakhiwo, ukukhiqizwa kwamasilinda angaphakathi nangaphandle wamabhodlela afakwe ngaphakathi kuhlukaniswe kwaba imigqa emibili yezinsiza, efingqiwe kulayini wezinto zomphakathi ngesikhathi somhlangano. Imodeli eyisisekelo imi kanjena:

Isilinda sangaphakathi

Ukuhlolwa kweKhanda (okwenziwe ngezifiso kwangaphandle) - insimbi yomhlangano wombhobho wekhanda (isiteshi sokushisela i-argon arc) - ukulethwa endaweni yomhlangano womzimba wesilinda (inqola yempahla) - Ukuhlolwa kwepuleti lokulinganisa (ukucubungula kwangaphandle noma ukuzicubungula ngokwakho) - ukugoqa (i-3-axis ipuleti rolling machine, enezingxenye ezincane ezigoqekayo eziqondile) - idlulisela esiteshini sokuwelda se-longitudinal (i-trolley yempahla) - i-longitudinal seam welding othomathikhi (inqubo ye-TIG, i-MIG noma i-plasma welding, ngokusho kwesilinda somzimba we-cylinder nobukhulu bodonga bumisiwe) - it iyiswa esiteshini sokushisela ngekhanda (inqola yempahla) - iwelding ye-girth ezenzakalelayo (ukukhiya ukukhiya nokufaka, ukufakwa kwe-MIG) - ukuhambisa umzimba wesilinda (ipulatifomu yetafula le-roller) kusuka kolunye uhlangothi lwe-opharetha - ukuhlanza nokucindezela ukuhlolwa - ukubeka kwimoto ejikayo - ukugoqa ungqimba lokwahlukanisa (ithuluzi lokwehlukanisa okwehlukile) - ukuhlangana nesilinda yangaphandle (mpo nangaphandle kumthetho wokuphakamisa ion yomshini ogoqayo) Inhlangano yomgqomo)

Isilinda sangaphandle

Ipuleti lobude (ukucubungula kwangaphandle noma ukuzicubungula ngokwakho) ukuhlolwa - ukugoqa kwendilinga (umshini wokugoqa ipuleti eyi-3-eksisi, onengxenye encane egoqayo) - ehambisa esiteshini se-longitudinal seam welding (i-material trolley) - i-longitudinal seam welding automatic (TIG, MIG noma i-plasma inqubo yokuwelda, enqunywa ngokusho kwesilinda nobukhulu bodonga) - idlulisela esiteshini sokushutheka kwenhlangano ngekhanda (inqola yempahla) - ukushisela okuzenzakalelayo okuzungezile (ukukhiya ukufaka ukukhiya, ukufakwa kwe-MIG) - kusukela ekusebenzeni Umbhali uqedile ukufakwa kwesilinda ehambisanayo ehambisanayo (ipulatifomu le-roller table) - ikhoyili yokupholisa yedramu yangaphakathi yokushisela udonga (igesi welding) - yibeke emotweni ejikayo - bese uhlangana nesilinda yangaphakathi (mpo yomzimba wesilinda ongaphandle esiteshini sokuphakamisa somshini ogoqayo)

Imikhiqizo eqediwe yamasilinda angaphakathi nangaphandle

Okokusebenza okuhlanganisiwe kufakwe ikhanda langaphandle - i-othomathikhi ye-girth welding (i-MIG welding) - ebekwe ekujikeni kwetrololi - ihumushela owokusebenza ibhande elihambayo elihambisanayo - i-welding i-fastener yangaphandle nesibambo sekhanda lesilinda (i-manual argon arc welding) - Ukuhlolwa komtshina ovuzayo

Ukupakisha nokugcina impahla

Emikhunjini emikhulu ye-cryogenic, ulayini we-logistics kanye ne-longitudinal girth welding kukhiqizwa ngokusemgqeni ofanayo, kanye ne-trolley yokuhambisa impahla, i-longitudinal girth welding, i-welding ezenzakalelayo yekhoyili yokupholisa ithusi odongeni lwangaphakathi lwesilinda sangaphandle, ukupholisha umgqomo nokuhlola, njll, kunqunywa ngokwesimo sangempela sokukhiqiza. Ngokuvamile, inqubo imi kanje:

Ukuhlolwa kwensimbi okwenziwe ngokwezifiso - ukuhambisa esiteshini sokugudluza - ukuphakamisa i-vacuum sucker esigabeni sokondla - ukondla nokugoqa - ukususa umzimba oyisilinda - iwelding seam longitudinal (kusetshenziswa i-plasma noma i-MIG welding) - ukuphuma esiteshini somsila se-longitudinal (okungaphakathi isilinda imbozwe ifilimu lokufaka elishisayo, kanti isilinda yangaphandle ishiselwe ngekhoyili yokupholisa ithusi) - ukuhlangana kwekhanda - ukufakwa kwamabhande - ukuqedwa kwensimbi yomhlangano wesilinda wangaphakathi nangaphandle - Ukupholisha udonga olungaphandle egumbini lokupholisha elivaliwe - Ukuhlolwa kokuvuza kokuvuza - ukupakisha nokugcinwa.

ukuphepha

Ngokuvamile, ibhodlela likaDewar linama-valve amane, okungukuthi i-valve yokusetshenziswa ketshezi, i-valve yokusebenzisa igesi, i-valve ye-vent kanye ne-booster valve. Ngaphezu kwalokho, kunegeji yomfutho wegesi negeji yeleveli yamanzi. Ibhodlela le-Dewar alihlinzekwa kuphela nge-valve yokuphepha, kepha futhi ne-disc eqhumayo [6]. Lapho ingcindezi yegesi esesilinda yeqe ingcindezi yohambo ye-valve yokuphepha, i-valve yokuphepha izogxuma ngokushesha futhi ikhiphe ngokuzenzekelayo futhi iqede ingcindezi. Uma i-valve yezokuphepha ihluleka noma isilinda sonakele ngengozi, ingcindezi esesilinda ikhuphuka kakhulu ezingeni elithile, isethi yamapuleti okuqhuma izokwehla ngokuzenzakalela, futhi ingcindezi ekulesi silinda izokwehliswa ibe ingcindezi yasemkhathini ngesikhathi. Amabhodlela eDewar agcina i-oxygen liquid liquid, eyandisa kakhulu umthamo wokugcina umoya-mpilo.

Kunezindlela ezimbili zokusebenzisa amabhodlela eDewar

(1) I-valve yokusetshenziswa kwegesi yamabhodlela kaDewar: xhuma umkhawulo owodwa wepayipi lensimbi elinengcindezi enkulu ku-valve yokusetshenziswa kwegesi yamabhodlela kaDewar bese kuthi omunye umkhawulo uye ezininginingi. Qala uvule i-valve yokuqala, bese uvule kancane kancane i-valve yokusebenzisa igesi, engasetshenziswa. Izibhedlela eziningi zisebenzisa kuphela i-valve yesigaba segesi ukuhlangabezana nezidingo zegesi.
(2) I-valve yedewar esebenzisa uketshezi lwamanzi, isebenzisa ipayipi lensimbi elinengcindezi enkulu ukuxhuma ipayipi le-valve yetshezi le-Dewar ne-vaporizer, ubukhulu be-vaporizer buhlelwe ngokuya ngokusetshenziswa kwegesi, ipayipi lensimbi elingenamthungo lisetshenziselwa ukuhambisa igesi, futhi kufakwa i-valve yokusiza ingcindezi, i-valve yokuphepha kanye negeji yokucindezela epayipini ukulawula ukuphepha kohlelo lokuphakelwa kwegesi, olungagcini nje ngokwenza lula nokusimamisa ukusetshenziswa kwegesi, kodwa futhi nokuqinisekisa ukusetshenziswa okuphephile. Uma usebenzisa ibhodlela le-Dewar, qiniseka ukuthi ukuxhumana kuhle, bese uvula i-valve yokusebenzisa uketshezi. Uma ingcindezi yegesi ingakwazi ukuhlangabezana nezidingo zokusetshenziswa, vula i-valve yokulekelela, linda imizuzu embalwa, ingcindezi izokhuphuka futhi ihlangabezane nezidingo zokusetshenziswa.
