Boiler zitsulo machubu ndi mipope, Amatanthauza malekezero awiri a gawo lotseguka ndi dzenje, kutalika kwake ndi periphery ya chitsulo chokulirapo, malinga ndi njira yopanga akhoza kugawidwa mu chubu chosasunthika chitsulo ndi chubu chitsulo chosungunulira, machubu achitsulo ndi mawonekedwe akunja. miyeso (monga m'mimba mwake kapena kutalika kwa mbali) ndi makulidwe a khoma, kukula kwake ndi kwakukulu kwambiri, kuchokera kumimba yaying'ono ya chubu cha capillary mpaka mamita angapo a chitoliro chachikulu.Machubu achitsulo amatha kugwiritsidwa ntchito popopera, zida zotenthetsera, mafakitale amakina, kufufuza kwamafuta amafuta, zotengera, mafakitale opanga mankhwala ndi zolinga zapadera.

Boiler zitsulo machubu ndi mapaipi, Ogawanika zitsulo chitoliro ndi welded zitsulo chitoliro (msoko chitoliro) magulu awiri.Malinga ndi gawo mawonekedwe akhoza kugawidwa mu chubu wozungulira ndi chubu wapadera woboola pakati, chimagwiritsidwa ntchito zozungulira zitsulo chubu, koma pali angapo lalikulu, amakona anayi, semicircle, hexagonal, equilateral makona atatu, octagonal wapadera woboola pakati zitsulo chubu.Pakuti chitoliro zitsulo pansi kuthamanga madzimadzi kuchita hayidiroliki mayeso kuyesa mphamvu yake kuthamanga ndi khalidwe, pansi pa kuthamanga mwachindunji si kutayikira, chonyowa kapena kutambasuka kwa oyenerera, ena zitsulo chitoliro molingana ndi muyezo kapena zofunika za mayeso mbali, flaring. test, flattening test.

Boiler Steel Tubes Ndi Mapaipi, Njira Zopangira

Machubu achitsulo owiritsa ndi mapaipi, ndi mtundu wa chubu wopanda msoko.Njira yopangira ndi yofanana ndi chitoliro chopanda msoko, koma pali zofunika kwambiri pamtundu wazitsulo zomwe zimagwiritsidwa ntchito popanga chitoliro chachitsulo.Malinga ndi ntchito kutentha lagawidwa mitundu iwiri ya ambiri boiler chubu ndi mkulu-anzanu kukatentha kukatentha chubu.

Boiler zitsulo machubu ndi mipope, makina katundu ndi index yofunika kuonetsetsa serviceability komaliza zitsulo.Zimatengera kapangidwe kake kachitsulo ndi njira yochizira kutentha.Muyeso wa chitoliro chachitsulo, malingana ndi zofunikira zosiyanasiyana zogwiritsira ntchito, zimatchula mphamvu zowonongeka (mphamvu zamakokedwe, mphamvu zokolola kapena zokolola, elongation) ndi kuuma, zizindikiro zolimba, komanso zofunikira za wogwiritsa ntchito kutentha kwakukulu ndi kochepa.

① Kutentha kwa chubu chonse kumakhala pansi pa 350 ℃, chitoliro chapakhomo chimakhala chopangidwa ndi No. 10, ayi.20 kaboni chitsulo chowotcha chitoliro kapena chitoliro chozizira chokoka.

② Machubu opopera opopera kwambiri amagwiritsidwa ntchito nthawi zambiri kutentha kwambiri komanso kupanikizika kwambiri.Pansi pa kutentha kwakukulu kwa gasi ndi nthunzi yamadzi, makutidwe ndi okosijeni ndi dzimbiri zidzachitika.Chitoliro chachitsulo chimafunika kuti chikhale ndi mphamvu zolimba kwambiri, kukana kwa kutukuta kwa okosijeni komanso kukhazikika kwa microstructure.

Machubu a Zitsulo za Boiler Ndi Mapaipi, Gwiritsani Ntchito

(1) Chubu cha boiler chambiri chimagwiritsidwa ntchito kwambiri popanga chubu lamadzi, chubu lamadzi otentha, chubu chamadzi otentha kwambiri, chubu chamoto chotenthetsera, chitoliro chachikulu ndi chaching'ono chautsi ndi chitoliro cha njerwa.

(2) chubu chotenthetsera chapamwamba chimagwiritsidwa ntchito makamaka popanga chubu chamoto chotenthetsera, chubu chotenthetsera, chitoliro, chitoliro chachikulu cha nthunzi, ndi zina zotere. Kapangidwe kake kamakampani kachulukidwe kamphamvu kachulukidwe kambiri nthawi zambiri kumakhala kokhazikika, koma kupezeka ndi kufunikira kwa aliyense. magawo ang'onoang'ono adzasiyanitsidwanso.Ogwira ntchito m'mafakitale akuwonetsa kuti ulalo wofunikira kwambiri ndikugwiritsa ntchito ndikulimbikitsa zida zamachubu zotenthetsera kwambiri za 20g kuti zisungidwe zatsopano zopulumutsa mphamvu.

Zatsopano zopulumutsa mphamvu 20g zopangira machubu okwera kwambiri zikuchulukirachulukira pamsika, monga utoto wobiriwira woteteza zachilengedwe, zinthu zopulumutsa mphamvu komanso zopulumutsa madzi m'bafa, mwala woteteza chilengedwe, bolodi loteteza simenti ya thovu, kupulumutsa mphamvu ndi zinthu zoteteza chilengedwe pamsika waukulu wa 20g high-pressure boiler tube industry zikulonjeza.[1]

Boiler Zitsulo Zitsulo Ndi Mapaipi, Zimango Properties Of

Kulimba kwamakokedwe
Pakukhazikika kwamphamvu, mphamvu yayikulu (Fb) yachitsanzo pakuthyoka imachokera ku kupsinjika (σ) kwa gawo loyambira (So) lachitsanzocho, chomwe chimatchedwa mphamvu yamphamvu (σb), yowonetsedwa N/mm2 (MPa).Zimayimira mphamvu yaikulu yazitsulo zachitsulo kuti zithetse kuwonongeka pansi pa zovuta.Fomula yowerengera ndi:

Kumene: Fb-- mphamvu yochuluka yotengedwa ndi chitsanzo ikasweka, N (Newton);Kotero-- Gawo loyambirira lachitsanzo, mm2.

Zokolola
Zipangizo zachitsulo ndi chodabwitsa zokolola, chitsanzo mu ndondomeko yamakokedwe mphamvu si kuwonjezeka (kusunga nthawi zonse) akhoza kupitiriza kukulitsa kupsyinjika, wotchedwa zokolola mfundo.Ngati mphamvu ikuchepa, zokolola zapamwamba ndi zochepa ziyenera kusiyanitsa.Gawo la zokolola ndi N/mm2 (MPa).

Malo okolola apamwamba (σ SU) ndizovuta kwambiri zomwe zitsanzo zisanaperekedwe ndipo mphamvu ikutsika kwa nthawi yoyamba.Malo otsika (σ SL) : kupanikizika kochepa mu gawo la zokolola pamene zotsatira zoyamba zosakhalitsa sizikuganiziridwa.

Zokolola zitha kuwerengedwa ndi:
Kumene Fs ndi mphamvu zokolola (nthawi zonse) ya chitsanzo panthawi yamphamvu, N (Newton) Momwemonso ndi gawo loyambirira lachitsanzo, mm.²

Boiler Zitsulo Ndi Mapaipi, Elongation Pambuyo Kusweka

Pakuyesa kwamphamvu, kuchuluka kwautali kumawonjezeka ndi mtunda wokhazikika pambuyo kukoka kwa chitsanzocho ndipo kutalika kwa mtunda wokhazikika kumatchedwa elongation.Gawoli ndi %.Fomula yowerengera ndi:

Kumene: L1-- mtunda wa chitsanzo pambuyo kusweka, mm;L0-- Utali woyambirira wa mtunda wa zitsanzo, mm.

Kuchepetsa gawo
Pakuyesa kwamphamvu, kuchuluka kwa kuchepetsedwa kwakukulu kwa gawo lodutsa pagawo locheperako lachitsanzo chikakokedwa ndipo gawo loyambirira lopatsirana limatchedwa gawo lochepetsera dera.ψ imawonetsedwa mu %.Fomula yowerengera ili motere:

Kumene, S0-- gawo loyambirira lachitsanzo, mm2;S1-- Malo ocheperako pang'onopang'ono pamtunda wocheperako wa chitsanzo mutasweka, mm2.

Kuuma index
Kuuma ndi kuthekera kwa chitsulo kukana zinthu zolimba kukanikiza pamwamba.Malingana ndi njira yoyesera ndi kuchuluka kwa ntchito, kuuma kungathe kugawidwa mu Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, micro hardness ndi kutentha kwakukulu.Zomwe zimagwiritsidwa ntchito popanga zitoliro zimakhala ndi brinell, rockwell, Vickers kuuma 3 mitundu.

A, Brinell hardness (HB)
Mpira wachitsulo kapena mpira wa carbide wa mainchesi ena umakanikizidwa pachitsanzo ndi mphamvu yoyesera yodziwika (F), ndipo mphamvu yoyesera imachotsedwa pakapita nthawi yodziwika kuti muyeze mainchesi a indentation (L) pachitsanzo.Nambala ya kuuma kwa Brinell ndi quotient ya mphamvu yoyesera yogawidwa ndi dera la indentation sphere.Kuwonetsedwa mu HBS, gawoli ndi N/mm2 (MPa).

Boiler Steel Tubes Ndi Mapaipi, Ubwino Ndi Kuyang'ana

Zofotokozera ndi Mawonekedwe

(1) GB3087-2008 "Seamless Steel pipe for Low and medium pressure boiler" zopatsa.Kufotokozera kwa machubu achitsulo opangira ma boiler osiyanasiyana, ma diameter 10 ~ 426mm, mitundu 43 yonse.Pali mitundu 29 ya makulidwe a khoma kuchokera ku 1.5 mm mpaka 26mm.Komabe, makulidwe akunja ndi makulidwe a khoma la chitoliro cha nthunzi yotentha kwambiri, chitoliro chachikulu cha utsi, chitoliro chaching'ono cha utsi ndi chitoliro cha njerwa chomwe chimagwiritsidwa ntchito mu boiler ya locomotive zimanenedwa mwanjira ina.
