Hlahisa:
Mehleng ena ea kajeno moo boiketlo le katleho li nkoang e le tsa bohlokoa haholo. Ha ho kenngoa kapa ho nkeloa sebaka ke mela ea khase, ho bohlokoa ho sebelisa thepa ea boleng bo holimo ho netefatsa polokeho le ho qoba likotsi life kapa life tse ka bang teng. Blogeng ena, re tla hlahloba melemo le lintho tse lokelang ho nahanoa ka ho sebelisa liphaephe tse welded ka arc tse koahetsoeng ka hare ho liphaephe tsa khase tsa setofo ho fumana kutloisiso e felletseng ea hore na ke hobane'ng ha e le khetho e ntle.
Melemo ea phaephe e phuthetsoeng ka arc e qoelitsoeng ka hare ho spiral:
1. Ho Tšoarella le Matla:
Liphaephe tsa SSAW (Spiral Submerged Arc Welded) li tsebahala ka ho tšoarella le matla a tsona a ikhethang. Liphaephe tsena li etsoa ka theknoloji ea spiral e etsang hore botenya bo tšoane ho pholletsa le phaephe. Botšepehi bona ba sebopeho bo netefatsa ts'ebetso e tšepahalang esita le tlas'a khatello e phahameng le maemo a mocheso, e leng se etsang hore e lokele ho kenngoa ha liphaephe tsa khase ka har'a litofo.
2. Ntlafatsa ho hanyetsa ho bola:
Liphaephe tsa SSAW Hangata li entsoe ka tšepe ea boleng bo holimo e nang le khanyetso e ntle ea mafome. Sena se bohlokoa haholo liphaepheng tsa khase ea tlhaho, moo likarolo tse senyang li ka behang botšepehi ba phaephe kotsing. Ka ho sebelisa phaephe e welded ka arc e koahetsoeng ka spiral, u ka ntlafatsa polokeho ea phaephe ea hau ea khase ka ho fokotsa kotsi ea ho lutla kapa ho hloleha ha phaephe ka lebaka la mafome.
3. Tlhomamiso e tenyetsehang le e loketseng:
Phaephe ea SSAW e loketse mefuta e fapaneng ea lipeipi tsa khase. Ho tenyetseha hona ho etsa hore ho be bonolo ho e laola ho potoloha litšitiso, ho boloka nako le chelete. Ho feta moo, phaephe e phuthetsoeng ka arc e spiral e hloka manonyeletso a fokolang ho feta mefuta e meng ea lipeipi, e fokotsang libaka tse ka bang teng tsa ho hloleha le ho netefatsa sistimi ea khase e sa lutleng.
Litlhokomeliso tsa ho sebelisa liphaephe tse welded ka arc tse koahetsoeng ka hare ho spiral ka har'a liphaephe tsa khase ea tlhaho:
1. Ho kenya setsebi:
Leha phaephe e welletsoeng ka arc e spiral e nang le spiral e fana ka melemo e mengata, ho bohlokoa hore e kenngoe ke setsebi se nang le boiphihlelo. Litsebi tse nang le mangolo li ka netefatsa hore liphaephe li koetsoe hantle, likhokahano li kentsoe hantle, 'me khatello e lekoa ho thibela likotsi life kapa life tse ka bang teng tsa polokeho.
2. Tlhokomelo e lekaneng:
Joalo ka karolo efe kapa efe tsamaisong ea khase, tlhokomelo ea kamehla e bohlokoa ho netefatsa ts'ebetso e tsoelang pele ea liphaephe tsa SSAW. Hopola ho hlahloba matšoao a ho tsofala kapa tšenyo 'me u netefatse hore liphaephe tsa hau li sirelelitsoe linthong tse ka ntle tse ka amang botšepehi ba tsona. Ka ho nka mehato ena ea ho itšireletsa, u ka lelefatsa bophelo ba liphaephe tsa hau tsa khase.
Ha re phethela:
Khetho ea thepa ea mothapo oa khase ea setofo e bapala karolo ea bohlokoa ho netefatseng polokeho le ts'ebetso e ntle ka ho fetisisa. Ka ho khetha phaephe e kopantsoeng ka arc e spiral, u ka rua molemo ho tšoarelleng ha eona ho phahameng, ho hanyetsa mafome le ho tenyetseha. Leha ho le joalo, ho bohlokoa ho itšetleha ka ho kenngoa ha litsebi le tlhokomelo ea kamehla ho eketsa melemo ea ho sebelisa phaephe e kopantsoeng ka arc e spiral bakeng sa liphaephe tsa khase. Ha u ntse u phehella sistimi ea setofo e tšepahalang le e sebetsang hantle, ho sebelisa thepa ea boleng kamehla ke ntho ea bohlokoa.
