Iyo Kugadzira Maitiro eIndasitiri Mavharuvhu

Ona Mufananidzo Mukuru
Wakambozvibvunza kuti mavharuvhu eindasitiri anogadzirwa sei?Iyo pombi system haina kukwana pasina mavharuvhu.Sezvo kuchengetedzeka uye hupenyu hwesevhisi zviri izvo zvinonyanya kunetsa mukufambiswa kwepombi, zvakakosha kuti vanogadzira mavharuvhu vaunze mavharuvhu emhando yepamusoro.

Chii chakavanzika chepamusoro pekushanda mavharuvhu?Chii chinoita kuti vave nani mukuita?Ndizvo zvinhu here?Michina yekuenzanisa ine basa zvakanyanya here?Chokwadi ndechekuti, zvese izvi zvinhu.Asati atombonzwisisa maminiti eiyo valve yeindasitiri, munhu anofanirwa kuziva zvakawanda nezve magadzirirwo anoita mavharuvhu.

Ichi chinyorwa chichakurukura kugadzirwa kwemavharuvhu eindasitiri kubva pakutanga kusvika kumagumo.Izvi zvaizopa vaverengi ruzivo nezve kugadzirwa kwevhavha uye kugadzirisa.

1. Kurongeka uye Kugadzira

Chekutanga, mutengi anofanira kuisa odha, ingave iri vharuvhu yakagadziridzwa kana chimwe chinhu chinowanikwa mune rondedzero yezvagara zviripo mavharuvhu magadzirirwo.Panyaya yeyakagadziriswa, kambani inoratidza dhizaini kune mutengi.Kana yangobvumirwa neyekupedzisira, mumiririri wekutengesa anoisa hurongwa.Mutengi anopawo pre-yakatsanangurwa dhipoziti kune kambani.

2. Inventory

Kana kuiswa kwemaodha uye dhizaini kwatanga, dhipatimendi rekugadzira rinotsvaga zvigadzirwa zvehunde, spool, muviri, uye bonnet.Kana paine zvinhu zvisina kukwana, dhipatimendi rekugadzira richatenga zvinhu izvi kubva kune vatengesi.

3. Kuzadza Rondedzero

Kana zvinhu zvese zviripo, timu yekugadzira inoenda pamusoro pechinyorwa zvakare kuti ive nechokwadi chekuti zvese zvakwana.Iriwo panguva ino kuti kubvumidzwa kwekupedzisira kunyorwa kwedhizaini kunoitika.Pamusoro pezvo, timu yekusimbisa mhando inotarisa zvinhu zvakanyatsonaka.Izvi ndezvekuona kuti mbishi zvinhu zvemhando yepamusoro.

4. Nzira yekugadzira

Izvi zvinosanganisira ruzhinji rwezviitwa zvine chekuita nekugadzirwa kwemavharuvhu eindasitiri.Chikamu chimwe nechimwe chikuru chinogadzirwa chimwe nechimwe.Kazhinji, pane chinyorwa chekutarisa chinosanganisira ese mazita ezvisara uye izvo zvekushandisa pane chimwe nechimwe.

Iri panguva ino apo mutungamiri weboka anopa nguva yekugadzira chaiyo, kubva pakutanga kwekushanda kusvika pakupera.Zvakare, mutungamiri anowanzo dhirowa hurongwa hwekuita hwakadzama.

Zvinokurukurwa pasi apa inzira mbiri dzinozivikanwa dzekuti mavharuvhu anogadzirwa sei.

#1: Nzira yekukandira

Nzira yekukanda inogona kupfupikiswa nekutarisa mufananidzo uri pazasi.Ziva kuti iyi haisi iyo nzira yakakwana.

● Muviri
Chinhu chekutanga chakaumbwa chakacheneswa.Nzira yekushandura inoitwa mushure mekuchenesa.Kutendeuka inzira yekubvisa zvinhu zvakawandisa nekucheka uchishandisa lathe kana muchina wekutenderedza.Zvinosanganisira kubatanidza muviri wakagara wakaumbwa pagomo uye kumuchina wekutenderera.Muchina uyu unotenderera nekumhanya kukuru.Ichiri kutenderera, chinocheka-chete chinocheka muviri kuita unodiwa uye chaiwo maumbirwo.Kunze kweizvozvo, kutendeuka kunogonawo kugadzira grooves, maburi, pakati pevamwe.

Nhanho inotevera ndeyekuwedzera simbi yekuputira, kazhinji, mhangura kune zvikamu zvakasiyana zvemuviri.Copper plating inovimbisa kuvharwa kwakakwana uye kwakaringana kwemuviri.

Nhanho inotevera ndeyekupenya kwemuviri.Zvadaro, nyanzvi dzinogadzira tambo dzinobvumira kubatanidzwa kwemamwe mavharuvhu kune zvimwe zvikamu kana mapaipi.Mavharuvhu anoda maburi saka kukomba kunoitikawo mushure meizvi.Cherechedza kuti valve yega yega ine hukuru hwakasiyana hwegomba, zvichienderana nezvinodiwa.Apa ndipo panopinda mirau nezviyero.

Vanamazvikokota vanobva vapenda mavharuvhu neTeflon kana mamwe marudzi eelastomer.Mushure mekupenda, kubika kunotevera.Teflon zvisungo nemuviri kuburikidza nekubika.

● Chigaro
Chigaro chinopinda maitiro akafanana nemuviri.Sezvo chigaro chiri mukati memuviri uye sechikamu chebasa rayo revharuvhu- kuti chisimbiso chiri nani- chinoda kukwana kwakakwana pakunamatirwa kwayo.Nepo muviri uchingove neTeflon, chigaro sechimwe chekuputira rabha kuti ive nechokwadi chekusimba.

● Dzinde
Sezviri munyaya yehunde, haifaniri kuva nekugadzirwa kwakawanda.Asi, kucheka izvi muzvikamu zvakafanira kwakakosha.

#2: Forged Method

Iyo nzira yekunyepedzera inogona kupfupikiswa mukuita uku pazasi.Saizvozvo, maitiro ari pazasi anongoratidza chete kuti nzira yekunyepedzera ndeyei.

● Kucheka uye Kugadzira
Mushure mekusarudzwa kwezvinhu, nzira inotevera ndeyekucheka muhurefu hunodiwa uye hupamhi.Nhanho inotevera ndeyekugadzira chikamu chimwe nechimwe nekudziisa zvishoma kune imwe nhanho.

● Kuchekerera
Nhanho inotevera ndeyekucheka.Apa ndipo panobviswa zvinhu zvakawandisa kana burr.Tevere, mutumbi unopenya kuti uuumbe muchimiro chevharuvhu chaiyo.

● Kuputika kwejecha
Sandblasting ndiro danho rinotevera.Izvi zvinoita kuti vharuvhu iite nyore uye yakachena.Saizi yejecha rinoshandiswa zvinoenderana nezvinodiwa nevatengi kana zviyero.Mavharuvhu anotanga arongwa kuti abvise akaremara.

● Machina
Machining inowedzera hukuru uye maumbirwo eshinda, maburi uye anofarira, zvakare, zvichienderana nekugadzirwa uye zvinodiwa nemutengi.

● Kurapa Kwepamusoro
Iyo valve inobata kumwe kurapwa kwepamusoro uchishandisa mamwe maasidhi uye anofarira.

5. Gungano

Gungano ndiyo nhanho iyo nyanzvi dzinobatanidza zvikamu zvevharuvhu kune imwe neimwe.Kazhinji kazhinji, gungano rinoitwa nemaoko.Iri panguva ino iyo technician inopa nhamba dzekugadzira mavharuvhu pamwe chete nemazita maererano nemirairo yainotevera seDIN kana API uye zvinoda.

6. Pressure Test

Muchikamu chekuyedza kudzvanywa, mavharuvhu anofanirwa kuita bvunzo dzekumanikidza kuti dzibude.Mune zvimwe zviitiko, mhepo ine 6-8 bar pressure inozadza valve yakavharwa kweimwe nhamba yemaawa.Inogona kubva pamaawa maviri kusvika pazuva, zvichienderana nehukuru hwevhavha.

Kana paine kuvuza mushure menguva, kugadziriswa kwevhavha kunoitika.Zvikasadaro, vharuvhu ichaenda kune chikamu chinotevera.

Mune zvimwe zviitiko, kuvuza kunoonekwa kuburikidza nekumanikidza kwemvura.Kana vharuvhu isingabvi sezvo huwandu hwemvura hunowedzera, inopasa bvunzo.Izvi zvinoreva kuti vharafu inogona kumira kuwedzera kudzvinyirira.Kana paine kuvuza, vharuvhu inodzokera kudura.Vanamazvikokota vanozotarisa kuti pane kuvuza here vasati vaita imwe seti yekumanikidza bvunzo kune iyi batch yemavharuvhu.

7. Kuongorora uye Kudzora Kwehutano

Panguva ino, vashandi veQA vaizonyatsoongorora mavharuvhu kuti adonhe uye mamwe zvikanganiso zvekugadzira.

Tarisa vhidhiyo iyi kuti uone kuti valve yebhora inogadzirwa sei.

Muchidimbu

Iyo indasitiri yekugadzira mavharuvhu maitiro ibasa rakaoma.Haisi kungosikwa kuri nyore kwevhavha.Zvinhu zvakawanda zvinobatsira pakubudirira kwayo: kutenga zvinhu, machining, kupisa kupisa, welding, kusangana.Mavharuvhu anofanirwa kuita bvunzo dzakasimba kuti ive nechokwadi chekushanda kwakanaka vasati vagadziri vazvipa kune mutengi.

Mumwe angabvunza, chii chinoita vharafu yepamusoro?Chimwe chezvinhu zvinosarudza zvekuziva mavharuvhu emhando yepamusoro ndeye bvunzo yenguva.Mavharuvhu ebasa refu anoreva kuti ndeemhando yakanaka.

Kune rumwe rutivi, kana vheji ichiratidza kubuda kwemukati, mikana iripo, nzira dzekugadzira dzinoshandiswa hadzisi mukati memitemo inodiwa.Kazhinji, mavharuvhu ari nani anogona kugara kusvika kumakore mashanu nepo akaderera-mhando anogona kungogara kusvika kumakore matatu.
