Kusiyana pakati pa mavavu apakhomo ndi mavavu ochokera kunja kumawonekera makamaka m'mbali zotsatirazi:
1. Zipangizo ndi njira:
Ma valve otumizidwa kunja: nthawi zambiri zinthu zopangira zosankhidwa, monga chitsulo chosapanga dzimbiri (monga 316L), ma alloy apadera kapena mapulasitiki aukadaulo. Njira yopangira (monga kupangira molondola, kupangira thovu lotayika) ndi njira yopangira ndi yapamwamba kwambiri. Kapangidwe ka mkati mwa kupangira ndi kokhuthala, pali zolakwika zochepa, ndipo mawonekedwe ake ndi osalala. Zipangizo zotsekera (monga EPDM, Viton, PTFE, ndi zina zotero) ndi zapamwamba kwambiri ndipo zimakhala ndi kukana kwabwino kwambiri kwa kuwonongeka, kukana dzimbiri komanso kukana kutentha kwambiri.
Ma valve apakhomo: Pali zinthu zosiyanasiyana zomwe mungasankhe, koma kupezeka ndi kugwiritsa ntchito bwino kwa zinthu zina kapena zapadera (monga chitsulo chapamwamba kwambiri, Hastelloy AlloyB) sikungakhale kolemera ngati mitundu yochokera kunja. Njira zopangira ndi kupangira zinthu zikupitirirabe kusintha, koma ubwino ndi mawonekedwe ake (monga kutsirizitsa pamwamba, kukonzedwa kwa burr) a zinthu zina zitha kukhala zosiyana ndi zinthu zochokera kunja. Kagwiridwe ka ntchito ka zinthu zotseka zinthu kakusintha, koma kukhazikika kwa nthawi yayitali komanso moyo wabwino nthawi zina umafunika kutsimikiziridwa.
2. Kapangidwe ndi magwiridwe antchito:
Valavu yochokera kunja: lingaliro la kapangidwe kake, kukonza kapangidwe kake, magwiridwe antchito abwino amadzimadzi komanso kukana kuyenda pang'ono. Kulondola kwa kukonza kwake kuli kwakukulu kwambiri, ndipo kufalikira kwa ziwalozo kumayendetsedwa mosamala kuti zitsimikizire kuti valavuyo ikugwira ntchito bwino popanda kugwedezeka. Kutseka, kutayikira kwakukulu (nthawi zambiri mpaka mulingo wa ANSIVI kapena pafupi ndi zero kutayikira), nthawi yayitali yogwira ntchito. Imagwira ntchito bwino pansi pa kupanikizika kwakukulu, kutentha kwambiri, dzimbiri lamphamvu, kuwonongeka kwambiri ndi zina zogwirira ntchito.
Ma valve apakhomo: Kapangidwe kake kamagwiritsa ntchito zinthu zomwe zakula kapena kukhwima, ndipo luso lodziyimira pawokha lakula m'zaka zaposachedwa. Kulondola konse kwa kukonza kukukulirakulira, koma zinthu zina sizingakhale zokwanira pankhani yowongolera kulekerera komanso kusasinthasintha mwatsatanetsatane. Kugwira ntchito kotseka kumatha kukwaniritsa zofunikira pamikhalidwe yanthawi zonse yogwirira ntchito, koma pansi pa miyezo yapamwamba kapena mikhalidwe yovuta, kuthekera ndi moyo wosunga kutayikira konse kwa nthawi yayitali zitha kukhala zotsalira poyerekeza ndi zinthu zotumizidwa kunja. Kukhazikika kwa magwiridwe antchito ndi chimodzi mwazinthu zofunika kwambiri zomwe ogwiritsa ntchito amasamala nazo.
3. Kuwongolera khalidwe ndi miyezo:
Ma valve otumizidwa kunja: Machitidwe okhwima owongolera khalidwe (monga ISO9001, ndi zina zotero) nthawi zambiri amagwiritsidwa ntchito, njira zopangira zimayendetsedwa mosamala, ndipo njira zoyesera zimakhala zathunthu (monga kuyesa kosawononga, kuyesa kupanikizika, kusanthula zinthu). Zogulitsa nthawi zambiri zimagwirizana ndi miyezo yapadziko lonse lapansi (monga API, ANSI, DIN, JIS, ndi zina zotero) ndipo zimakhala ndi ziphaso zonse.
Ma valve apakhomo: Chidziwitso cha khalidwe chawonjezeka kwambiri, ndipo opanga ambiri okhazikika adutsanso satifiketi ya ISO ndikukhazikitsa (GB) kapena miyezo yamakampani. Komabe, milingo yowongolera khalidwe imasiyana kwambiri pakati pa opanga osiyanasiyana, ndipo zida zoyesera za opanga ena ang'onoang'ono ndi apakatikati sizingakhale zokwanira kapena kukhazikitsa sikungakhale kokhwima mokwanira. Chiŵerengero cha zinthu zovomerezeka chikuwonjezeka.
4. Mtengo ndi mtengo:
Ma valve otumizidwa kunja: Mtengo nthawi zambiri umakhala wokwera kwambiri kuposa wa ma valve apakhomo, makamaka chifukwa cha zinthu monga mtengo wa zinthu, kafukufuku waukadaulo, njira zopangira, ndalama zolipirira mtundu, mitengo, ndi zinthu zoyendera.
Ma valve apakhomo: ali ndi kuthekera kwakukulu, makamaka chifukwa cha kutsika kwa ndalama zopangira zinthu, kutsika kwa ndalama zogwirira ntchito komanso kupanga zinthu m'deralo.
5. Nthawi yotumizira ndi ntchito:
Ma valve otumizidwa kunja: Nthawi yotumizira ndi yayitali, makamaka pazinthu zosakhazikika kapena zosinthidwa, zomwe zingatenge miyezi ingapo. Kuthamanga kwa ntchito yogulitsa pambuyo pogulitsa kumakhala kochepa malinga ndi malo, ndipo kupezeka kwa zida zosinthira kungatenge nthawi yayitali komanso kukhala kokwera mtengo.
Ma valve apakhomo: Nthawi yotumizira ndi yochepa, ndipo kupezeka kwa zinthu zapoyera kapena zachizolowezi kumafulumira. Kuyankha kwautumiki wapafupi ndi kwachangu, chithandizo chaukadaulo, kukonza ndi kupereka zida zosinthira ndi kosavuta komanso panthawi yake, ndipo mtengo wake ndi wotsika.
Ma valve olowetsedwa kunja, ma valve owongolera ochokera kunja, olowetsedwa kunjamavavu a gulugufe, W&T
Chidule:
Ma valve apakhomo ali ndi ubwino woonekeratu m'mapulojekiti omwe ali ndi mikhalidwe yogwirira ntchito nthawi zonse, kukhudzidwa kwa mitengo, komanso zofunikira kwambiri pakutumiza, ndipo mulingo wawo wonse ukusintha nthawi zonse. Ma valve ochokera kunja nthawi zambiri amakhala abwino kwambiri pankhani ya zipangizo, luso, kapangidwe, kudalirika, magwiridwe antchito ndi moyo wautumiki pansi pa mikhalidwe yogwirira ntchito, koma ndi okwera mtengo ndipo amakhala ndi nthawi yayitali yotumizira. Mukasankha, muyenera kuganizira mozama mikhalidwe yeniyeni yogwirira ntchito (kupanikizika, kutentha, mawonekedwe apakati), bajeti, nthawi ya polojekiti, ndi ziyembekezo za kudalirika ndi moyo. Pamikhalidwe yovuta kapena yovuta yogwirira ntchito, zinthu zotumizidwa kunja zikadali njira yofunika kwambiri; m'magwiritsidwe ntchito ambiri, ma valve apakhomo ndi chisankho chofala kwambiri.
Ma valve otumizidwa kunja ali ndi ukadaulo wokhwima komanso magwiridwe antchito okhazikika, ndipo ndi oyenera kugwira ntchito molimbika komanso movutikira, koma ndi okwera mtengo. Ma valve osungira madzi apakati komanso otsika mphamvu m'nyumba, omwe akuimiridwa ndiTWS, ndi zotsika mtengo m'minda yamavavu a gulugufe, mavavu a chipatandima valve owunikira, ali ndi yankho lachangu lautumiki, ndipo ndi oyenera kugwira ntchito nthawi zonse.
