Imiyalo yokusetshenziswa kokufakwa kwamapayipi ancibilika kagesi

Isakhiwo esiyisisekelo sokuncibilika kukagesiukufakwa kwepayipi.

Amathuluzi wokushisela i-fusion kagesi:

Umshini wokushisela kagesi, umshini wokusika amapayipi, isikrufu, umshini wokugaya, irula, ipeni lokumaka, isibhamu sokushisela i-extrusion, intambo yokushisela yepulasitiki (yokuvalwa)

Izinyathelo zokufaka:

1. Ukulungiselela:

Hlola ukuthi ukunikezwa kwamandla kungaphakathi kwebanga elidingwa umshini wokushisela, ikakhulukazi i-voltage ye-generator.Hlola ukuthi umthamo wezintambo uyahlangabezana yini nezidingo zamandla okukhiphayo we-welder kanye nokubeka phansi kwentambo yaphansi.(Ngobubanzi obungu-Φ250mm noma ngaphansiukufakwa kwepayipi, amandla omshini ohlanganisiwe kufanele abe mkhulu kuno-3.5KW;Kokufakwa amapayipi okungu-Φ315mm noma ngaphezulu, amandla omshini ohlanganisiwe kufanele abe mkhulu kuno-9KW.Amandla kagesi nakagesi kufanele ngaso sonke isikhathi agcinwe ebangeni elingu-±0.5 yenani elimisiwe).

2. Ukunqanyulwa kwamapayipi:

Ubuso bokugcina bepayipi kufanele bunqunywe nge-perpendicular ku-axis ngephutha elingaphansi kuka-5 mm.Uma ubuso bokugcina bepayipi bungahambisani ne-axis, kuzokwenza ukuthi indawo ye-weld ibonakale, ibangele amaphutha okushisela njengezinto ezincibilikisiwe ezigeleza epayipini.Ubuso bokuphela kwepayipi kufanele buvalwe ngemva kokunqunywa kwepayipi.

3. Ukuhlanza indawo yokushisela:

Linganisa futhi umaka ukujula noma indawo yokushisela epayipini ngokumaka.Ngenxa yokuthi ipayipi le-polyethylene ligcinwa isikhathi esithile, ungqimba lwe-oxide luzokwakhiwa phezulu.Ngakho-ke, kuyadingeka ukususa ngokuphelele ungqimba lwe-oxide endaweni yangaphandle yepayipi kanye nodonga lwangaphakathi lombhobho ngaphambi kwe-welding, okuzothinta ikhwalithi ye-welding futhi kubangele izingozi zokuphepha.Ukunwetshwa kwendawo yokushisela kudinga ukujula okungu-0.1-0.2mm.Ngemuva kokukhuhla, ukuhlanza imiphetho kanye nemiphetho yezindawo zangaphakathi nangaphandle zepayipi.

4. Isokhethi yamapayipi nezinto ezifakwayo:

Ukufakwa kwepayipi elincibilikisa kagesi elihlanziwe lifakwa epayipini ukuze lishiselwe, futhi unqenqema lwangaphandle lwepayipi lugubha ngomugqa wokumaka.Lapho ufaka, i-terminal yepayipi kufanele ibekwe endaweni elula yokusebenza.Ukufakwa kufanele kube ngaphansi kwezimo ezingenakucindezeleka futhi ipayipi ifakwe ndawonye.Lungisa isihlanganisi phakathi kokufakwa kanye nepayipi ku-concentricity efanayo kanye nezinga, futhi umumo we-V awukwazi ukuvela epayipini.Uma ububanzi obungaphandle bepayipi bukhulu kakhulu, indawo engaphezulu yepayipi eshiselwe kufanele iphinde ichithwe ukuze kutholakale ukulingana okufanele.Uma ukufakwa kanye nepayipi kukhulu kakhulu ngemuva kokufakwa kwesokhethi, i-hoop kufanele ilengiswe ngokuqinile ukuze i-welding.

5. Faka i-centralizer:

I-centralizer kufanele idlale indima yokuqinisa isokhethi, ukuqinisekisa ukuthi akulula ukunyakaza lapho i-welding;umsebenzi wegebe elihambisanayo phakathi kokufakwa kwepayipi kanye nepayipi ukwenza ipayipi ingaguquki.Lungisa izindandatho ezimbili ze-snap ye-centralizer endaweni efanele yepayipi, futhi kufanele ibekwe ngemuva kophawu ukuze ugweme ukufakwa kwepayipi endaweni, qinisa inadi ye-snap ye-centralizer, futhi uyibambe epayipini.Naka isiqondiso sembobo yesikulufu se-centralizer ngesikhathi sokufakwa, funa ungakwazi ukufaka isikulufu sokunene.

6. Isixhumi esiphumayo:

Ukuphela kokukhishwa kwe-welding kuxhunywe ngokuqinile nokufakwa kwamapayipi.Uma usayizi ophumayo uhlukile kusayizi wepayipi, ipulaki yezintambo ezifanayo kufanele isetshenziswe.

7. Amarekhodi okushisela:

Ngemva kokufaka imingcele yokushisela okuyiyonayona, cindezela ukhiye u-Enter ukuze uqale ukushisela.Ekupheleni kwenqubo yokushisela, umshini wokushisela ukwazisa ngokuzenzakalelayo.Imingcele yokushisela irekhodwa ngesikhathi sokushisela ukulandelela nokuhlaziya ikhwalithi yokwakha.Ngokusho kwezinga lokushisa lendawo yesayithi kanye noshintsho lwe-voltage yokusebenza, isikhathi sokushisela singanxeshezelwa kahle ngesikhathi sokushisela.Uma izinga lokushisa liphansi, ukugcinwa kokushisa kufanele kwenziwe kahle ekufakeni ipayipi le-electrofusion yokushisela.

8. Ukupholisa:

Ngesikhathi se-welding kanye nesikhathi sokupholisa, ucezu oluxhumayo alukwazi ukunyakaza noma lusetshenziswe ngamandla angaphandle, futhi ipayipi akufanele ihlolwe ingcindezi uma ucezu lokuxhuma lungapholi ngokwanele (hhayi ngaphansi kuka-24h).
