1.Precautions bakeng sa ts'ebetso ea welding
Ha ho chesoa, ts'ebetso e lokela ho etsoa ka tieo ho latela mehato, ho seng joalo, boleng ba welding bo tla ameha.
(1) Bokaholimo ba lisebelisoa tsa lipeipi tse lokelang ho chesetsoa li lokela ho hloeka kapa ho chesoa.Molomo o tukang o lokela ho ba o boreleli, o chitja, o se na makukuno le mapetso, 'me o lekana ka botenya.Lokisetsa lipeipi tsa koporo hore li kenngoe ka sandpaper, 'me qetellong u li hlakole ka lesela le omeletseng.Ho seng joalo e tla ama phallo ea solder le boleng ba soldering.
(2) Kenya liphaephe tsa koporo ho welded overlapping mong ho e mong (ela hloko boholo ba), le ho lolamisa bohareng ba selikalikoe.
(3) Ha ho chesoa, likarolo tse cheselitsoeng li tlameha ho futhumatsoa pele.Chesa karolo ea tjheseletso ea phala ea koporo ka lelakabe, 'me ha phala ea koporo e futhumatsoa ho ba bopherese bo bofubelu, sebelisa eleketrode ea silevera ho e cheselletsa.Ka mor'a hore lelakabe le tlosoe, solder e itšetlehile ka motsoako oa solder, e le hore solder e qhibilihe ebe e phalla likarolong tsa koporo tse rekisoang.Mocheso ka mor'a ho futhumatsa o ka bonahatsa mocheso ka 'mala.
(4) Ho molemo ho sebelisa lelakabe le matla bakeng sa ho cheselletsa ka potlako, le ho khutsufatsa nako ea ho cheselletsa ka hohle kamoo ho ka khonehang ho thibela li-oxide tse feteletseng hore li se ke tsa hlahisoa phapeng.Li-oxides li tla baka litšila le tšitiso ka holim'a phallo ea sehatsetsing, esita le ho baka tšenyo e kholo ho compressor.
(5) Ha solder e sa tiisoa ka ho feletseng, u se ke ua sisinya kapa ua sisinya phala ea koporo, ho seng joalo karolo e soldered e tla ba le mapheo 'me e baka ho lutla.
(6) Bakeng sa tsamaiso ea sehatsetsi e tlatsitsoeng ka R12, ha e lumelloe ho chesella ntle le ho ntša metsi ka sehatsetsing sa R12, ’me ho ke ke ha khoneha ho lokisa litšepe ha tsamaiso ea sehatsetsi e ntse e lutla, e le ho thibela sehatsetsi sa R12 hore se se ke sa e-ba chefo. ka baka la malakabe a bulehileng.Phosgene e chefo 'meleng oa motho.
2. Mokhoa oa ho cheselletsa likarolo tse fapaneng
(1) Welding ea phasewete bophara fittings phala
Ha o tjheseletsa liphaephe tsa koporo tse bophara bo lekanang tsamaisong ea sehatsetsing, sebelisa tjheseletsa ea casing.Ke hore, phala e cheselitsoeng e atolosoa ka senoelong kapa molomong oa tšepe, ebe ho kenngoa phala e 'ngoe.Haeba ho kenngoa ho le khutšoanyane haholo, ho ke ke ha ama matla le ho tiea feela, empa hape ho phalla ho tla phalla habonolo ka phala, ho baka tšilafalo kapa ho thibela;haeba lekhalo pakeng tsa liphaephe tse ka hare le tsa ka ntle li le nyenyane haholo, phallo e ke ke ea phalla ka holim'a sepakapaka 'me e ka kenngoa feela ka ntle ho sebopeho.Matla a fokola haholo, 'me a tla petsoha le ho lutla ha a thothomela kapa a kobeha;haeba lekhalo le lekanang le le leholo haholo, phallo e tla phalla habonolo ka phala, e bakang tšilafalo kapa ho thibela.Ka nako e ts'oanang, ho lutla ho tla bakoa ke ho tlatsoa ha flux e sa lekaneng ka har'a weld, eseng feela boleng Ha bo botle, empa hape le tšenyo ea thepa.Ka hona, ke habohlokoa haholo ho khetha bolelele ba ho kenya le lekhalo pakeng tsa liphaephe tse peli ka mokhoa o utloahalang.
(2) Welding ea capillary tube le koporo tube
Ha ho lokisoa mochini o omisang mochini oa sehatsetsing, tube ea capillary (throttle capillary tube) e lokela ho ts'oaroa.Ha capillary e chesellelitsoe ho se omisang filthara kapa liphaephe tse ling, ka lebaka la phapang e kholo lipakeng tsa bophara ba phala e 'meli, matla a mocheso oa capillary a nyane haholo,' me ketsahalo ea ho chesa haholo e atisa ho eketsa thollo ea metallographic ea capillary. , e fetohang brittle le bonolo ho robeha.E le ho thibela capillary hore e se ke ea chesa haholo, lelakabe la ho cheselletsa khase le lokela ho qoba capillary le ho etsa hore le fihlele mocheso oa welding ka nako e le 'ngoe le tube e teteaneng.Sekotwana sa tšepe se ka boela sa sebelisoa ho tiisa letlapa le teteaneng la koporo holim'a tube ea capillary ho eketsa sebaka sa ho qhala mocheso ka nepo ho qoba mocheso o feteletseng.
(3) Welding ea capillary tube le filter dryer
Botebo ba ho kenngoa ha capillary bo lokela ho laoloa ka har'a 5-15mm ea pele, qetellong ea ho kenngoa ha capillary le mochini o omisang mochini o lokela ho ba 5mm ho tloha qetellong ea skrine ea sefe, 'me lekhalo le lekanang le lokela ho ba 0.06 ~ 0.15mm.Qetellong ea capillary e molemo ka ho fetisisa ho etsoa ka lehlakoreng la pere ea 45 ° ho thibela likaroloana tse tsoang linaheng tse ling hore li se ke tsa lula holim'a qetellong le ho baka ho thibela.
Ha li-diameter tse peli tsa liphaephe li fapane haholo, mochine o omisang sefe o ka boela oa siloa ka pipe clamp kapa vise ho batalatsa phala e ka ntle, empa capillary e ka hare e ke ke ea hatelloa (e shoele).Ke hore, kenya tube ea capillary ka har'a tube ea koporo pele, 'me u e hatelle ka pipe clamp e bohōle ba 10 mm ho tloha qetellong ea tube e teteaneng.
(4) Welding ea peipi ea sehatsetsing le conduit ea compressor
Botebo ba phala ea sehatsetsing e kentsoeng ka phala e tlameha ho ba 10mm.Haeba e le ka tlase ho 10mm, peipi ea sehatsetsing e tla tsoela ka ntle habonolo nakong ea mocheso, e leng se etsang hore phallo e thibele molomo.
3. Tlhahlobo ea boleng ba welding
E le ho etsa bonnete ba hore ha ho na ho lutla ho hang karolong e cheselitsoeng, tlhahlobo e hlokahalang e lokela ho etsoa ka mor'a ho cheselletsa.
(1) Lekola hore na ts'ebetso ea tiiso ea weld e ntle.Kamora ho eketsa sehatsetsing kapa naetrojene ho tsitsisa nako e itseng, e ka lekoa ka metsi a sesepa kapa mekhoa e meng.
(2) Ha ts'ebetso ea sehatsetsing le ea moea e sebetsa, ha ho mapetsong (seams) sebakeng sa welding ka lebaka la vibration e lokelang ho lumelloa.
3
(4) Ha mosebetsi oa sehatsetsing le o futhumatsang moea, bokaholimo ba karolo ea tjheseletsa bo lokela ho hloeka le ho hloka matheba a oli.
