Mavavu osapanga dzimbiri ndi oyenera kugwiritsidwa ntchito pamapaipi owononga komanso mapaipi a nthunzi. Iwo ali ndi mikhalidwe ya kukana dzimbiri, kukana kutentha kwambiri komanso kukana kwamphamvu. Nthawi zambiri amagwiritsidwa ntchito m'mapaipi owononga m'mafakitale amankhwala, komanso mapaipi m'madzi apampopi kapena m'mafakitale azakudya. Mpweya wazitsulo wa carbon alibe kukana kwa dzimbiri ndipo ungagwiritsidwe ntchito pa mapaipi osawononga sing'anga monga nthunzi, mafuta, madzi, ndi zina zotero. Mtengo wa mavavu a carbon zitsulo ndi wotsika kwambiri kuposa wa chitsulo chosapanga dzimbiri, choncho nthawi zambiri palibe nthunzi yowononga ndi zina. mapaipi amagwiritsidwa ntchito. Chitsulo cha kaboni chimagwiritsidwa ntchito, ndipo mavavu achitsulo chosapanga dzimbiri ndi zinthu zina zimagwiritsidwa ntchito pochita dzimbiri. Zotsatirazi ndi kufotokozera mwachidule za kusankha kwa ntchito kwa valavu yachitsulo chosapanga dzimbiri ndi valavu ya chipata cha carbon steel ndi NSW Valve:
1 Chifukwa chiyani kutayikira kwa valavu ya carbon steel ndi chiyani
Carbon steel pachipata valve ndi valavu ya mafakitale, yomwe imagwiritsidwa ntchito kwambiri mu petroleum, mankhwala, magetsi ndi mafakitale ena. Ili ndi zabwino zake zokha, zosavuta kugwiritsa ntchito, komanso moyo wautali wautumiki, koma mukamagwiritsa ntchito
Panthawiyi, chifukwa cha mphamvu yake yokha kapena zinthu zakunja, valve ya carbon steel pachipata idzatuluka. Ndiye, chifukwa chiyani kutayikira kwa valavu ya chipata cha carbon steel ndi chiyani? Mfundo zazikuluzikulu ndi izi
zifukwa wamba.
1. Kutsika kochepa kwachitsulo chosindikizira chosindikizira chopangidwa ndi mphero kumabweretsa kutuluka kwamkati kwa valve ya carbon steel gate. Malingana ngati valve yachipata cha mtundu waukulu imasankhidwa, ubwino wa zida zosungirako nthawi zambiri zimakhala bwino, kotero kuti kulondola kwa ndondomeko ya mphete yosindikiza sikudzakhala kochepa.
1. Kusakhazikika kwa kupanga ndi machitidwe ogwiritsira ntchito kumayambitsa kutuluka kwamkati kwa valve yachipata. Valve yachipata ili ndi zofunikira kwambiri pazomwe zimagwirira ntchito. Ngati kupanikizika ndi kutentha kwa chilengedwe kumakhala kosasunthika ndipo kusintha kwakusintha kuli kwakukulu kwambiri, kukakamiza kwa mphete yosindikiza kudzakhala kwakukulu, komwe kumakhala kosavuta. Deformation imachitika, yomwe pamapeto pake imayambitsa kutayikira kwa valve.
3. Kusamalidwa bwino kwa valavu kumabweretsa kutuluka kwamkati kwa valve yachipata. Ogwira ntchito ena samayeretsa malo osindikizira a mphete yosindikizira pamene akukonzanso valavu. Kukhalapo kwa zonyansa kudzakhudza ntchito ya valve. M'kupita kwa nthawi, malo osindikizira adzagwedezeka, zomwe zidzachititsa kuti valve iwonongeke.
4. mphete yosindikizira yooneka ngati dzimbiri ya chishango imapangitsa kuti valavu ya pachipata idutse kwa nthawi yayitali. Mothandizidwa ndi sing'anga, mphete yosindikizira imawonongeka mosavuta. Ngati dzimbiri zifika pamlingo wina, mphete yosindikizira idzanenedwa, kotero kuti valavu imatulutsa.
5. Thupi la valve ndi lolakwika. Ngati thupi la valve liri ndi mavuto monga pores, slag inclusions, ming'alu, mabowo a mchenga, ndi zina zotero, ndiye kuti valavu ya chipata imakonda kutuluka kunja panthawi yogwiritsira ntchito.
Mwachidule, kutayikira kwa carbon steel chipata valve ndi vuto wamba. Ngati pali kutayikira, kuyika pachiwopsezo chitetezo cha zida ndi antchito, chifukwa chake ndikofunikira kudziwa chomwe chimayambitsa ndikuthetsa vutoli munthawi yake.
4 Momwe mungasankhire valavu yodalirika yosapanga dzimbiri
Osiyana ndi valavu wamba pneumatic mpira, valavu agulugufe magetsi ndi zipangizo zina valavu, m'badwo pachipata safuna kusintha otaya sing'anga madzimadzi youma, koma amachita zonse lotseguka ndi odulidwa kwathunthu mu payipi.
Njira yosinthira imagwiritsidwa ntchito. Kotero pali ma valve ambiri osapanga dzimbiri pazipata zachitsulo pamsika, ndi mankhwala ati omwe ali odalirika kwambiri? Makhalidwe a zitsulo zosapanga dzimbiri mavavu pachipata
Chitsulo chosapanga dzimbiri chimapangidwa ndi chitsulo chosapanga dzimbiri. Chitsulo chosapanga dzimbiri komanso chithandizo chapamwamba ndi kuzimitsa ndi kutenthetsa m'malo mwake zimapangitsa chitsulo chosapanga dzimbiri kukhala mbali zabwino zotsutsana ndi dzimbiri komanso zabwino.
Abrasion, yotalika kwambiri. Choncho, valavu yachitsulo chosapanga dzimbiri nthawi zambiri imagwiritsidwa ntchito poyendetsa kayendedwe ka mankhwala, ndipo kusindikiza kwake kwabwino ndi kukana kwa dzimbiri kumapangitsa kuti kusakhale kosavuta kuphwanyidwa ndi kutsukidwa ndi sing'anga.
Kutentha kwapamwamba komanso kuthamanga kwambiri munthu kungathenso kuonetsetsa kuti ntchito yabwino yosindikiza. Ndi valavu iti yachitsulo chosapanga dzimbiri yomwe ili yabwinoko
Zimanenedwa kuti valavu yachitsulo chosapanga dzimbiri ndi chipangizo cha valve cha mafakitale, koma kwenikweni ndi chidwi kwambiri. Mwachitsanzo, ngati kusankha kwa valve ya pakhomo kuli kolakwika, zoopsa zosayembekezereka zikhoza kuchitika, choncho musatero
Valovu yachipata chachitsulo chosapanga dzimbiri iyenera kuyesedwa kupanikizika musanachoke ku fakitale. Pogula valavu, kasitomala ayenera kudziwanso kuchuluka kwa kuthamanga komwe valve imayenera kupirira pasadakhale kuti isankhe chitsanzo choyenera ndi ndondomeko.
Opanga nthawi zonse amakhala okhwima komanso olondola pakuyesa kukakamiza, kotero kaya ndi mtundu wa valve, moyo wautumiki, zotsika mtengo, kapena chitetezo.
Ndikofunikira kwambiri kusankha wopanga nthawi zonse komanso wodalirika, ndipo zopangidwa ndi opanga nthawi zonse (NSW Valve) ndizotetezeka kwambiri.
Makasitomala aliyense ali ndi zofunika zosiyanasiyana zowuma zitsulo zosapanga dzimbiri mavavu pachipata. Pankhani ya mtengo, khalidwe ndi chitetezo chamtundu, opanga osiyanasiyana nthawi zina amakhala ndi kusiyana koonekeratu. Choncho, kusankha opanga ayenera kuganizira zinthu zosiyanasiyana.
