Themkangano wowonjezerandi cholumikizira chomwe chimalipiritsa kusintha kwa kukula komwe kumachitika chifukwa chakukula kwamafuta ndi kuzizira kozizira mu kulumikizana kwa chitoliro.Pali mitundu iwiri yolumikizirana yolumikizira yomwe imagwiritsidwa ntchito kwambiri, imodzi ndi yolumikizira zitsulo ndipo inayo ndi yolumikizira mphira.
Kukula kwa mphira kumatchedwanso kuti mphira yosinthika, yolumikizira mphira, yolumikizana ndi mphira yosinthika komanso cholumikizira cha rabara.Amapangidwa makamaka ndi mbali tubular mphira wopangidwa ndi zigawo zamkati ndi kunja mphira, zigawo chingwe ndi zitsulo waya mikanda, amene vulcanized pa kutentha ndi kuthamanga kwambiri ndiyeno pamodzi ndi zitsulo flange manja lotayirira.
Kuchuluka kwa ntchito:Malumikizidwe okulitsa mphira ndi oyenera makamaka kulumikiza mapampu ndi mavavu, mapaipi okhala ndi kugwedezeka kwakukulu, ndi mapaipi omwe amasinthasintha pafupipafupi kuzizira ndi kutentha chifukwa cha magwiridwe antchito ake abwino.Amagwiritsidwanso ntchito kwambiri m'madzi a m'nyanja, madzi abwino, ozizira ndi otentha, madzi akumwa, zimbudzi zapakhomo, mafuta osakanizika, mafuta amafuta, mafuta opaka, mafuta opangira mafuta, mpweya, gasi, nthunzi ndi tinthu tating'onoting'ono ta ufa.Amagwiritsidwa ntchito kwambiri poteteza moto, mankhwala, ma valve ndi njira zina zamapaipi kuti achepetse chivomezi ndi phokoso komanso kuyamwa kusamuka komwe kumapangidwa panthawi ya payipi.
Zowonjezereka zowonjezera mphira:
1. Kukula kwakung'ono, kulemera kopepuka, kukhazikika bwino, kukhazikitsa kosavuta ndi kukonza.
2. Pakuyika, kusuntha kwa axial, transverse, longitudinal ndi angular kumatha kuchitika, komwe sikumakakamizidwa ndi chitoliro cha wosuta chosakhala pakati ndi flange chosafanana.
3. Pogwira ntchito, masanjidwewo amatha kuchepetsedwa kuti achepetse phokoso, ndipo mphamvu yoyamwa yogwedezeka imakhala yolimba.
4. Ndi mphira wapadera wopanga, imatha kukana kutentha kwambiri, asidi ndi alkali, ndi mafuta.Ndi payipi yosagwira ndi mankhwala;Mankhwala abwino.
Cholumikizira cholumikizira chitsulo ndi mawonekedwe osinthika omwe amayikidwa pachigoba cha chotengera kapena payipi kuti abwezere kupsinjika kowonjezereka komwe kumachitika chifukwa cha kusiyana kwa kutentha ndi kugwedezeka kwamakina.Monga chiwongola dzanja cholipirira chomwe chimakhala ndi kufalikira kwaufulu ndi kutsika, chakhala chikugwiritsidwa ntchito kwambiri m'magawo amankhwala, zitsulo, nyukiliya ndi zina chifukwa cha magwiridwe ake odalirika, magwiridwe antchito abwino, kapangidwe kake ndi maubwino ena.
Zofunikira za Metal Expansion:
Kukana kutentha kwakukulu, kukana kupanikizika kwakukulu, kubwezeredwa kwakukulu kwakukulu.
Malunjiro onse a mphira ndi zolumikizira zitsulo zili m'magulu a zida za mapaipi.Kwenikweni, kusiyana pakati pa zida ziwirizi zitha kuwoneka:
Thupi lalikulu la mgwirizano wokulitsa mphira ndi gawo lopanda kanthu lopangidwa ndi mphira, ndipo mbali zonse ziwiri zimalumikizidwa ndi flanges;Thupi lalikulu la zitsulo zowonjezera zowonjezera limapangidwa ndi zitsulo, ndipo mbali ziwirizo zimagwirizanitsidwa ndi flanges, ulusi wopota kapena grooves, looper flanges ndi mitundu ina yolumikizira.Kukula kwa mphira, chifukwa cha kukhathamiritsa kwake bwino, kulimba kwa mpweya, kukana kuvala, kukana kukakamiza ndi zabwino zina zambiri, sikungangolipira kusamutsidwa kwamakina a zida zapaipi, komanso kusintha kwa axial, transverse ndi angular kusamutsidwa chifukwa chakukula kwamafuta. ndi ma contraction zinthu monga chilengedwe, sing'anga, ndi zina zotero, ndipo zimatha kuyamwa kugwedezeka kwa zida, kuchepetsa kuipitsidwa kwaphokoso, kumathandizira kwambiri kuteteza kuwononga chilengedwe.
Kukula kwazitsulo nthawi zambiri kumatanthawuza cholumikizira chachitsulo cha payipi.Thupi lalikulu limapangidwa ndi chitoliro cha malata ndi wosanjikiza wa chitsulo chosapanga dzimbiri wolukidwa mauna, kapena zitsulo zosapanga dzimbiri zoluka mauna.Ndizosavuta kugwiritsa ntchito mumayendedwe ovuta a mapaipi kapena mapaipi okhala ndi unsembe wocheperako.Ndilo chosinthika chophatikizana cha machitidwe a mapaipi.
