Mukugadzirwa kwemaindasitiri, mamwe anoramba achishanda midziyo inodonha nekuda kwezvikonzero zvakasiyana. Zvakadai sepombi, mavharuvhu, midziyo, etc. Chizvarwa chekudonha uku chinokanganisa kugadzikana kwekugadzirwa kwakajairika uye kunaka kwezvigadzirwa, uye zvinosvibisa nharaunda yekugadzira, zvichikonzera tsvina isingakoshi. Zvakare, mushure mekudonha kweimwe midhiya yakaita sechepfu gasi uye girisi, zvinokonzeresa kukuvadza kukuru mukugadzirwa kwakachengeteka uye nharaunda yakatenderedza.
Semuyenzaniso, kuputika kwepombi yemafuta yeQingdao Huangdao musi waMbudzi 22, 2013 uye Tianjin Binhai New Area kuputika kwenzvimbo yekuchengetera zvinhu zvine njodzi musi waNyamavhuvhu 2, 2015 kwakakonzera kurasikirwa kukuru kwehupenyu nemidziyo kunyika nevanhu. Zvikonzero zvetsaona idzi zvose zvinokonzerwa nekudonha kuri pakati nepakati.
Naizvozvo, kuvuza kwezvimwe zvigadzirwa zvemaindasitiri hakugone kufuratirwa uye kunofanirwa kugadziriswa nenguva. Nekudaro, iro zvakare idambudziko rehunyanzvi maitiro ekugadzirisa kudonha kwemidziyo iri pasi pekumanikidzwa uye ine zvinhu zvinopisa uye zvinoputika kana chepfu chemakemikari media.
Kuvharirwa kwemidziyo nekumanikidza, oiri kana zvinhu zvine muchetura ndeye welding yakakosha pasi pemamiriro ekushanda asina kujairika. Iyo yakasiyana neyakajairwa welding yakatarwa uye inosimbisa kuchengetedzwa panguva yekushanda. Matanho ekuvaka ekuchengetedza kudzivirira tsaona anofanirwa kugadzirwa asati aturika kuti ave nechokwadi chekuchengetedzeka kwenzvimbo yebasa, welder nevamwe vashandi. Welders vanofanira kunge vane ruzivo uye vane hunyanzvi. Panguva imwecheteyo, panofanirwa kunge paine mainjiniya emagetsi ane ruzivo rwakapfuma rwehunyanzvi hwekupa hutungamiriri hwehunyanzvi pane akasiyana mashandiro akachengeteka.
Semuenzaniso, kune imwe mhando yetangi yemafuta, zvinodikanwa kuti uzive huwandu, nzvimbo yekubatidza, kudzvanywa, nezvimwe zvemafuta mukati, uye kuve nechokwadi kuti hapana kukuvara kwemunhu kana njodzi huru yekuchengetedza ichakonzereswa panguva yewelding. isati yavakwa uye kushanda.
Naizvozvo, pamberi uye panguva yekuvaka welding, zvinotevera zvinofanirwa kuitwa:
Kutanga, yakachengeteka kudzvinyirirwa. Usati welding kuti uvhare panovuza, zvinofanirwa kutariswa kana kudzvanywa kwemidziyo kuti isimbiswe kuchaita kukuvara kwemunhu. Kana pasi pesimba reiyo welding yekupisa sosi, iyo midziyo ine yakachengeteka yekuyamura nzira (yakadai sevhavha yekuchengetedza yakaiswa), nezvimwe.
Chechipiri, kudzora tembiricha. Pamberi pekuputira, matanho ese ekutonhora ekudzivirira moto uye kudzivirira kuputika kunofanirwa kuitwa. Munguva yewelding, ma welders anofanirwa kunyatsotevedzera hushoma uye hushoma kupisa kupinza kunotsanangurwa mugwaro rekuita, uye matanho ekutonhora ekuchengetedza anofanirwa kuitwa panguva yekushongedza kudzivirira moto kana kuputika.
Chechitatu, anti-chepfu. Pakuisa chisimbiso nekuisa midziyo yemoto kana pombi dzine chepfu, kufefeterwa nenguva kwemagasi ane muchetura akabvinza uye kupihwa kwemweya mutsva panguva yakakodzera kunofanira kuitwa. Panguva imwecheteyo, zvakakosha kuita basa rakanaka mukusvibiswa kwekuparadzaniswa kwekubuda kwezvinhu zvine chepfu.
Aya anotevera akati wandei ekushongedza plugging nzira dzinowanzoshandiswa muinjiniya kudzidzira kuti munhu wese adzidze nekuvandudza.
1 Hammer twist welding nzira
Iyi nzira inoshandiswa kune welding nzira yekuputika kana blister uye pores yemidziyo yakaderera-kudzvinyirira uye mapaipi. Shandisa madiki-dhayamita maelectrode ekushongedza zvakanyanya sezvinobvira, uye welding ikozvino inofanira kunyatsotevera maitiro ezvinodiwa. Iko kuvhiya kunotora nzira yekukurumidza welding, uye kupisa kwearc kunoshandiswa kupisa periphery yekudonha. Weld mupendero uchirova weld.
2. Riveting welding nzira
Kana mamwe makatsemuka akafara kana dhayamita yetrachoma kana buri remhepo rakakura, zvinonetsa kushandisa sando inomonyorora. Unogona kutanga kushandisa akakodzera simbi waya kana welding tsvimbo kuti rivet mutswe kana gomba kuderedza kumanikidzwa uye kuyerera leakage, uye ipapo kushandisa diki ikozvino kukurumidza Welding kuitwa. Pfungwa huru yeiyi nzira ndeyokuti chikamu chimwe chete chinogona kuvharwa panguva, uye zvino kukurumidza kusungirirwa, chikamu chimwe chakavharwa uye chimwe chikamu chinosungirirwa. Sezvakaratidzwa mumufananidzo 1
Kumwe kubuda kwemvura kunokonzerwa nekuora uye kupera nekutetepa. Panguva ino, usaite weld yakananga kudonha, zvikasadaro zviri nyore kukonzeresa kuwanda uye kudonha kukuru. Spot welding inofanira kuitwa panzvimbo yakakodzera pedyo kana pasi pemvura inonyudza. Kana nzvimbo idzi dzisina kubuda mvura, dziva rakanyungudutswa rinofanira kutanga ragadzirwa, uye, senyenganyenga yakabata madhaka uye ichivaka dendere, inofanira kunyudzwa zvishoma nezvishoma, zvishoma nezvishoma ichideredza ukuru hwekudeuka kwayo. nzvimbo, uye pakupedzisira shandisa diki-dhayamita electrode ine yakakodzera welding ikozvino kuvharira kunaya, sezvakaratidzwa muFigure 2.
Inokodzera kuputika kana nzvimbo yekudonha yakakura, chiyero chekuyerera chakakura kana kudzvinyirira kwakakwirira, sezvinoratidzwa muMufananidzo 3. Maererano nechimiro chekudonha, ita ndiro yekuwedzera ine chigadziro chekuvhara. Kana kuputika kwakakomba, chikamu chepombi yekutsaudzira chinoshandiswa pamudziyo wekuvhara, uye valve yakaiswa pairi; kana kudonha kuri kudiki, nati inofanosungirirwa pandiro yekugadzirisa. Nzvimbo yepatch plate inofanira kunge yakakura kudarika iyo inodonha. Nzvimbo yemudziyo wekubira pachigamba inofanira kunge yakatarisana nekudonha. Denderedzwa rechisimbiso rinoiswa padivi pechigamba chiri kudhumhana nekuvuza kuitira kuti yadeuka yepakati ibude ichibva pachubhu inotungamira. Kuderedza kuvuza kwakatenderedza chigamba. Mushure mekugadzirisa ndiro yakasungirirwa, vhara valve kana simbisa mabhoti.
Kana pombi ichinyuza munzvimbo yakakura nekuda kwekuora kana kupera, shandisa chidimbu chepombi ine dhayamita imwechete kana kungokwana kuti umbundire dhayamita rekudonha sesleeve, uye kureba kunoenderana nenzvimbo yekudonha. Cheka sleeve chubhu symmetrically muzvidimbu zviviri, uye weld diversion chubhu. Iyo chaiyo welding nzira yakafanana neye diversion welding nzira. Mukutevedzana kwewelding, mhete yemhete yepombi uye ruoko runofanira kutanga rwaiswa weld, uye weld yesleeve inofanira kusungirirwa kwekupedzisira, sezvakaratidzwa mumufananidzo 4.
6. Welding yeoiri leakage container
Kuenderera mberi welding haigone kushandiswa. Kuti ive nechokwadi chekuti tembiricha ye weld haigone kukwira zvakanyanya, nzvimbo yekushongedza inoshandiswa uye tembiricha inodzikiswa panguva imwe chete. Semuyenzaniso, mushure menzvimbo welding mapoinzi mashoma, pakarepo tonhodza majoini ekutengesa nemvura-yakanyoroveswa donje gauze.
Dzimwe nguva, zvinodikanwa kushandisa zvizere nzira dzepamusoro dzakasiyana dzekupura, uye welding plugging inoda kuchinjika kuitira kuti ive nechokwadi chekubudirira kweiyo welding plugging.
Zvisinei, hazvisi zvinhu zvose zvesimbi zvakakodzera nzira yekubatanidza plugging. Chete yakajairwa yakaderera kabhoni simbi uye yakaderera alloy simbi inogona kushandisa iri pamusoro akasiyana nzira dzekupura.
Austenitic Stainless Simbi inofanira kugadziriswa neWelding kana ichinge yatemwa kuti base simbi iri padhuze nekudonhedza inogona kuburitsa hombe yepurasitiki deformation, zvikasadaro haigone kugadziridzwa newelding.
Iyo yepakati mupombi yesimbi inodzivirira kupisa inowanzove yakakwirira-tembiricha uye yakakwirira-kumanikidza mutsi. Kudonha kunoitika mushure mekushanda kwenguva refu hakugone kugadziriswa pasi pekumanikidzwa. Kudzika-kupisa kwesimbi hakubvumirwi kugadziriswa ne-hot-press welding.
Idzo dziri pamusoro apa dzakasiyana-siyana welding plugging nzira ese ndeenguva nhanho, uye haana ma mechanic zvimiro zvesimbi izvo zvinogona kuwanikwa newelding mupfungwa yakasimba. Kana iyo midziyo iri pasi pemamiriro ekusamanikidzwa uye pasina svikiro, iyo yenguva pfupi plugging uye welding nyika inofanira kubviswa zvachose, uye zvakare-welded kana kugadziriswa neimwe nzira yekusangana nezvinodiwa zvekushandisa zvechigadzirwa.
pfupiso
Welding plugging tekinoroji tekinoroji yekukurumidzira inodiwa mukuenderera mberi kwekugadzira nekuvandudzwa kwekugadzirwa kwemazuva ano. Zvinotora imwe nguva yenguva kubata netsaona dzekuvuza, uye iyo inodonha inofanirwa kutsiviwa zvachose mushure. Iko kushandiswa kweiyo leak plugging tekinoroji inofanirwa kuchinjika. Kubata nekudonhedza, nzira dzakawanda dzinogona kushandiswawo kujoina welding. Chinangwa ndechekudzivirira kuvuza mushure mekucheka.
