Pamene kutentha ntchito mpweya zitsulo zosakwana -2 ℃, ndipo pamene kutentha ntchito mpweya zitsulo zosakwana 0 ℃, si koyenera kugwiritsa ntchito makina makina kukhomerera ndi kumeta ubweya. Zitsulo zokhuthala zomwe zimayambitsa ming'alu pambuyo podula waya ziyenera kutenthedwa pambuyo powotcherera, apo ayi chithandizo cha kutentha chiyenera kuchitidwa. The positi kuwotcherera kutentha mankhwala a flanged mphira kukulitsa olowa azichitika mogwirizana ndi zofunikira za DL/T752, koma chachikulu positi kuwotcherera kutentha mankhwala, kutentha ulamuliro kutentha adzakhala 2 ℃ ~ 3 ℃ m'munsi kuposa pakati ndi otsika. kutentha kwa zipangizo zoyambirira mbali zonse ndi kuwotcherera mafunsidwe.
Cholumikizira chamtundu wa mphira wa Flange chidzakhazikitsidwa motengera izi:
1. Kukonzekera: Tsukani mbali zonse ziwiri za payipi, yeretsani flange ndi zosindikizira, ndipo onani ngati ma flange, mabawuti, ndi ma gaskets ali bwino komanso osawonongeka.
2. Kuyika kwa flange: gwirizanitsani flange ya mphira yowonjezera ndi flange mbali zonse za payipi, perekani bawuti kudutsaflangedzenje, ndikuyika mafuta oyenera pa mtedza wa flange.
3. Sinthani mgwirizano wowonjezera: mutatha kukonza flange, sinthani njira ndi malo a mphira yowonjezera ya rabara kuti ikhale yachilengedwe ndikupewa kupanikizika kwakukulu kapena kupanikizika.
4. Ndodo ya nangula yokhazikika: Ngati nangula flange ikufunika, ndodo ya nangula iyenera kulumikizidwa ndi flange ndikumangirira pansi kapena bulaketi kudzera pazida zokhazikika monga mbale za nangula.
5. Zitsulo zolimba: sungani ma bolts mosinthana kuchokera kumbali zonse ziwiri mpaka ma bolt onse atsekedwa mofanana komanso mozama kuti atsimikizire kuti kusindikiza ndi kugwirizanitsa ntchito pakati pa flange ndi mphira yowonjezera mphira.
6. Kuyang'ana: potsiriza, fufuzani ngati ndondomeko yonse yoyika ikukwaniritsa zofunikira, ndikutsimikizirani ngatimkangano wowonjezeraimayikidwa bwino
Zida ndi kukhazikitsa kwa flanged mphira kukulitsa olowa zimasonyeza kupatuka kwina, kotero izo zikhoza kusinthidwa molingana ndi zenizeni unsembe specifications pa unsembe ndi kukonza, ndi ma radial galimoto mphamvu akhoza kufalitsidwa ku mapulogalamu onse mapaipi dongosolo ntchito. Izi sizimangowonjezera magwiridwe antchito, komanso zimakhala ndi chitetezo china pazida zamakina zamapaipi monga mapampu ndi ma valve.
Malangizo oyika kwamphira wowonjezera wa flange. Pamene kutentha kumasintha, payipi imatha kufalikira momasuka ndikugwirizanitsa pakati pa mawonekedwe. Maziko akamira, mapaipi amatha kupendekeka ndikuwonetsetsa kuti palibe kutayikira posindikiza, ndiyeno kukhala ndi cholinga chobwezera basi.
Single flange malire mphira kukula olowa ndi oyenera kulumikiza ndi flange ndi kuwotcherera ndi payipi. Pakuyika, sinthani kutalika kwa msonkhano pakati pa mbali ziwiri za chinthucho ndi payipi kapena flange, limbitsani zomangira za nangula za chivundikiro cha valve molingana ndi ngodya yapamwamba, kenako sinthani mtedza kuti payipi ikule ndikulumikizana momasuka mkati mwa kuchuluka kwa kubweza ndi kubweza, kutseka kukulitsa ndi kutsika, ndipo payipi imatha kugwira ntchito modalirika. Flange yoletsa kukulitsa mphira ndi yoyenera kulumikiza mbali zonse za flange. Pakuyika, sinthani kutalika kwa kugwirizana kwa mbali zonse ziwiri za katunduyo, limbitsani mabawuti a bonnet mofanana pamwamba pa ngodya, ndiyeno sinthani nati woyikira, kuti payipi iwonjezeke ndikukulitsidwa mwakufuna kwawo, komanso kutalika kwa malekezero onse awiri. chipangizo chokulitsa chikhoza kusinthidwa. Kukula kwa mphira ndikoyenera kulumikiza mbali zonse ziwiri ndi payipi popanda kuwotcherera kwamagetsi, ndi kapangidwe koyenera, kusindikiza kwabwino, komanso kuyika mwachangu komanso kosavuta.
Cholumikizira cholumikizira mphira chokhala ndi malire a flange chimakhala ndi njira zingapo zosinthira mapaipi, ndipo chimagwira gawo lofunikira pakukulitsidwa kwa kukhumudwa kwapamtunda ndi mphindi yopindika chifukwa chakukula kwamafuta pamapaipi. Choncho, mphira kukulitsa olowa akhoza kuchepetsa kukankha mphamvu yambale wakhungupogwira ntchito ya payipi, ndipo ali ndi chisamaliro china cha payipi, makamaka pakukhazikitsa ndi kukonza payipi. Mbali imodzi ya flange yolepheretsa kukula kwa rabara idzakhala ndi zida zoyikira pamaziko a mawonekedwe oyambira olumikizirana mphira, ndipo ikhale yotsekedwa ndi mtedza pamalowo ndikukulitsa kwakukulu. Chitolirocho chikhoza kuwonjezeredwa mopanda malire mkati mwa njira yowonjezereka yololedwa, ndipo ikangopitirira kukula kwake, ikhoza kuonetsetsa kuti payipi ikugwira ntchito modalirika, makamaka pamapaipi omwe ali ndi kugwedezeka kapena kupendekera kwina ndi kutembenuka.
