Kugwiritsa Ntchito kwaSpiral Steel Pipemu Urban Central Heating

Kutentha chapakati m'tawuni amapangidwa ndi anaikira kutentha kwa nthunzi, madzi otentha wofatsa zitsulo chitoliro maukonde kudzera mumzinda kapena mbali ya Kutentha ntchito kupanga ndi moyo njira, yomwe imakhala ndi kutentha, maukonde kutentha, ogwiritsa kutentha magawo atatu.

Dongosolo lotenthetsera m'matauni, chitukuko cha zachuma ndi chikhalidwe cha anthu m'matauni, zomangamanga, ndi chitukuko chake ndi chizindikiro cha kusinthika kwamatauni.Kupanga malo otenthetsera m'matauni a "zomangamanga m'matauni ku China kwakhala lamulo lofunikira.

Central Kutentha cogeneration ndi kugawira makamaka kwa kupambana Kutentha poyerekeza, cholinga m'madera otsatirawa:

1, pali mtengo wabwino wandalama.Ma boilers otenthetsera chapakati ndi mphamvu yayikulu, kutentha kwambiri kumatha kufika 90%, ndipo kumwazikana kocheperako kumatenthetsa kutentha kumangokwana 60% kapena kuchepera.Chifukwa chake, m'malo momwaza kutentha kwapakati kumatauni palimodzi kumatha kupulumutsa mphamvu 20 mpaka 30%.

2, zabwino zachilengedwe phindu.Kuwonongeka kwa mizinda kumabwera makamaka chifukwa cha kuyaka kwa malasha komwe kumatulutsa mpweya woipa ndi mwaye.Kutentha kwapakati pa boiler mphamvu, komanso kukhala ndi zida zabwinoko zochotsera fumbi, pogwiritsa ntchito fyuluta yapamwamba kwambiri, kuchotsera fumbi 90 mpaka 98% kapena kupitilira apo, kumatha kuchepetsa kuipitsidwa kwamatawuni.

3, zabwino zothandiza anthu.Kutenthetsa kwapakati m'matauni kuti anthu azikhalamo, kupulumutsa malo omanga m'matauni amtengo wapatali, kuti achepetse kuchepa kwa magetsi m'matauni ofunika kwambiri.

Ocean engineering zitsulo chitoliro kapangidwe ndi kusankha, specifications ndi malinga ndi gulu la ocean engineering zitsulo kapangidwe, ndi ponena za API (American petroleum Institute), AISC (American gulu zitsulo dongosolo), ASTM (American gulu kuyesa ndi zipangizo ), ANSI (American National Standards Institute), ASTM (American Society of Testing and materials), AWS (American welding society), NACE (National Association of corrosion engineers) miyezo ndi malangizo.Kufunika kwa nyanja uinjiniya zipangizo zitsulo chitoliro, kwenikweni ndi chofunika mbale zitsulo palokha, ali otsika mpweya zitsulo, mkulu mphamvu zitsulo, kopitilira muyeso-mkulu mphamvu zitsulo, zosapanga dzimbiri magulu anayi.Tchulani mfundo ziwiri apa:

(1) uinjiniya wam'madzi wa zida zotumizidwa kunja kwambiri.Nthawi zina ku Britain zitsulo chubu ndi zitsulo chubu kupanga makamaka mkulu khalidwe zofunika.Mu uinjiniya wa m'nyanja ndi gawo lapadera la chubu chachitsulo, 100% zake zonse zimafunikira pakuyezetsa akupanga (UT - Ultrasonictesting) ndi kuyang'anira maginito (MT - Magnetictesting).Kuphatikizidwa mu dongosolo lalikulu la chitoliro chachitsulo, mumtundu wa 300 mm pa malekezero onse a msoko wautali amafuna 100% UT ndi MT.

(2) kupanga node ya chitoliro ndi ya zinthu zofunika kwambiri mu uinjiniya wa m'nyanja.Special chitoliro mfundo mafakitale kunja, ndi zoweta anamanga unit.Kuthekera kwa matani a 52000, mwachitsanzo, "ubwenzi" wanyanja ya bohai, unit yoyandama yosungiramo zinthu (FPSO, ndi kuphunzitsa imodzi mwazotumiza khumi zodziwika kwambiri ku China) za mkono wapadera wofewa (YOKE) ndi njira yolumikizira YOKE ndi bulaketi yothandizira, nsanja ya torch, thandizo la nsanja ya helikopita, etc. Pali ma node a 221, kuti akwaniritse zofunikira za AISC, AWS.59 km kutalika (kuphatikizapo remote control hydraulic chubu 28 km, 119 valavu yoyang'anira kutali, msewu wa tank 48).Sitima yapamadzi kuti muwonetsetse kuti zomangamanga zili bwino, sankhani kuchokera ku zikwizikwi za kuwotcherera kwabwino kwambiri, omaliza 15 amayenerera kukhala 6 gr gulu lamagulu.Mu nyanja zomangamanga pofuna kupewa kutayikira kwa mafuta ndi gasi dongosolo, si anatengera zitsulo chitoliro flange kugwirizana, ndipo utenga argon Arc kuwotcherera.Magulu atatu a TIG welder shipyard ndipo amafunikira maphunziro apadera.
