B. Uxhumano lwe-Electrofusion

C. Ukuhlolwa kokubukeka

D. Ukwakhiwa kwenqubo elandelayo

2. Ukulungiselela ngaphambi kokwakhiwa

1). Ukulungiswa kwemidwebo yokwakha:

Ukwakhiwa ngokuhambisana nemidwebo yokuklama okufanele yenziwe. Lapho iyunithi yokuklama inomdwebo wokwakha ophumelelayo, iyunithi yokwakha kufanele iye endaweni yokwakha ukuze iqonde isimo esithile. Ngengxenye engakwazi ukwakhiwa ngokusho komdwebo, kufanele idalule futhi ixoxisane neyunithi yokuklama ukuze inqume ukuthi ubuchwepheshe obukhethekile bokwakha noma izinguquko zendawo zendawo zingamukelwa. Ngesikhathi esifanayo, izinto zokwakha kanye nemishini kufanele kuthengwe ngokuvumelana nemidwebo, futhi isimiso sokwakha kufanele sihlelwe.

2). Ukuqeqeshwa kwabasebenzi:

Abaqhubi abaxhume ipayipi legesi le-polyethylene kumele bathole ukuqeqeshwa okukhethekile ngaphambi kokuthatha isikhundla, futhi bangathatha isikhundla kuphela ngemva kokuphasa ukuhlolwa nokuhlolwa kobuchwepheshe.

Ngaphezu kolwazi lwethiyori lolwazi lwegesi, izici zezinto ezikhethekile ze-polyethylene, ulwazi lukagesi, imishini yokushisela i-polyethylene, ubuchwepheshe bokwakhiwa kwepayipi legesi le-polyethylene nezinye izici zabasebenzi bokuqeqesha, futhi babambe iqhaza ekuhloleni.

3 ).Ukulungiswa kwemishini yokwakha kanye namathuluzi

Ngokwezidingo zobuchwepheshe bokwakha, lungiselela imishini yokwakha ehambisanayo namathuluzi. Ngenxa yokuthi ayikho indinganiso ehlanganisiwe yekhwalithi yokushisela kanye nemingcele yokushisela yamapayipi e-polyethylene ezweni lethu, imingcele yokushisela yepayipi, ukufakwa kwamapayipi kanye ne-PE ball valve ekhiqizwa abakhiqizi abahlukene ihlukile. Ukuze kuzuzwe umphumela we-welding onokwethenjelwa, ekukhethweni kwemishini kufanele futhi kukhethwe ngokucophelela, khetha imikhiqizo yekhwalithi enhle, kumphumela we-welding, ukuze ithembeke.

3. Ukwamukelwa kwepayipi, okokufakwa kanye ne-PE ball valve

1) Hlola ukuthi imikhiqizo inaso yini isitifiketi sefekthri kanye nombiko wokuhlolwa kwefekthri.

2）Hlola ukubukeka. Hlola ukuthi izindawo zangaphakathi nezangaphandle zepayipi zihlanzekile futhi zibushelelezi yini, nokuthi zikhona yini izisele, imidwebo, amazinyo, ukungcola nemibala engalingani.

3) Ukuhlola ubude. Ubude beshubhu kufanele bufane futhi iphutha akufanele lidlule ukuhlanganisa noma ukususa u-20 mm. Hlola ukuthi ubuso bokugcina bepayipi buhambisana yini ne-axis yepayipi ngayinye, nokuthi ngabe kukhona ama-pores. Amapayipi anobude obuhlukene angeke amukelwe ngaphambi kokuba kutholakale imbangela.

4). , okubonisa inhloso, ibanga lempahla eluhlaza, isilinganiso sikasayizi ojwayelekile, usayizi wokucaciswa, ikhodi evamile nenombolo ye-serial, igama lomkhiqizi noma uphawu lokuhweba, usuku lokukhiqiza.

5）isheke lokuyindilinga: Isilinganiso se-arithmetic semiphumela yokuhlolwa yamasampula amathathu sithathwa njengokuyindilinga kwepayipi, futhi inani lalo elingaphezu kuka-5% lithathwa njengelingafanelekile.

6） Hlola ububanzi bepayipi nobukhulu be-bi. Ububanzi bepayipi kufanele buhlolwe ngerula eliyindilinga, futhi ububanzi kuzo zombili iziphetho kufanele kulinganiswe. Noma iyiphi indawo engafaneleki izothathwa njengengafanelekile.

Ukuhlolwa kobukhulu bodonga kwenziwa nge-micrometer, ukulinganisa umjikelezo wamaphuzu amane aphezulu naphansi, noma yikuphi okungafanelekile.

7) Ipayipi, ukufakwa kwamapayipi, i-PE ball valve transport kanye nesitoreji

Ukuthuthwa nokugcinwa kwemikhiqizo ye-polyethylene kuzokwenziwa ngalezi zindlela ezilandelayo: Intambo engeyona insimbi kufanele isetshenziselwe ukubopha nokuphakamisa.

8）Ngeke ijikijele futhi ngomthelela wodlame, ingahle ingahuduli.

Akumele kuvezwe elangeni, emvuleni, namafutha, i-asidi, i-alkali, usawoti, i-ejenti esebenzayo nezinye izinto zamakhemikhali ezithintanayo.

9) Ipayipi, okokufakwa, i-PE ball valve kufanele igcinwe endaweni enomoya omuhle, izinga lokushisa alikho ngaphezu kuka-40 ℃, hhayi ngaphansi kuka -5 ℃ endaweni yokugcina impahla, ukupakishwa kwesikhashana endaweni yokwakha, kufanele kuhlanganiswe.

I-10 ) Enkambweni yokuthutha nokugcinwa, ithubhu encane ingafakwa ku-tube enkulu.

11 ) ukuthutha nokugcina kufanele kubekwe ngokuvundlile endaweni eyisicaba kanye negaraji, lapho kungejwayelekile, kufanele kumiswe izisekelo eziyisicaba, ukuhlukaniswa kwezisekelo kuya ku-1-1.5m kufanelekile, ukuphakama kokupakishwa kwamapayipi akufanele kudlule u-1.5m. .

I-12) Kuphakanyiswa ukuthi isikhathi sokugcina phakathi kokukhiqizwa nokusetshenziswa akufanele sidlule iminyaka engu-2, futhi isimiso "sokuqala ngaphakathi, ukuphuma kuqala" kufanele silandelwe lapho kusakazwa izinto.

4Izinyathelo zokuxhuma zikagesioi-fusion welding

1). Xhuma ukunikezwa kwamandla kwengxenye ngayinye ye-welder. Kumelwe isebenzise i-220V, 50Hz AC, ukushintsha kwamandla kagesi phakathi kuka-± 10%, ukunikezwa kwamandla kufanele kube ngocingo olusekelwe phansi; Lungiselela amathuluzi asizayo afana nomaka, i-flat scraper, irula eliyisicaba, ne-fixture fixture.

2） Lungiselela amapayipi nezinto zokufakwa ukuze zishiselwe, futhi ungawavuli amaphakheji okufakwa kwe-weld kusenesikhathi.

3) Ukufakwa okuthathu: khipha iphakheji yangaphandle yezixhumi zamapayipi, izifakelo zamapayipi ezibhalisiwe ezifakelweni zamapayipi ukuze zishiselwe ukwenza ukufakwa kwendawo yokumaka; Faka into yokulungisa futhi ulungise umhlangano ozofakwa ngefenisha; Vula ijakhethi ye-electrode yokufaka ipayipi bese ufaka i-electrode ephumayo ye-electric fusion welder ku-electrode yokufaka ipayipi.

4) Sebenzisa umshini wokushisela ngokuya ngenqubo yokusebenza endaweni yemingcele yokufaka i-welding, ngesandla (amapharamitha anikezwe ilebula yokufaka ipayipi)

5) Qala umshini wokushisela we-fusion kagesi ukuze uqale inqubo yokushisela, futhi umshini uzobona ngokuzenzakalelayo izinga lokushisa elizungezile futhi ulungise imingcele yokushisela. Ngemuva kokuthi inqubo yokushisela isiqediwe, umshini uzomisa ngokuzenzakalelayo isikhathi sokushisela kanye nokupholisa. Ngemuva kokuthi ukupholisa sekuqediwe, i-electrode kanye ne-fixture fixture ingasuswa ukuze isigaba esilandelayo sishiswe.

6) Phrinta irekhodi lepharamitha yenqubo yokushisela noma ukuphrinta okuphakathi nendawo kamuva.

5. Imingcele yenqubo yokushisela

Sebenzisa umshini wokushisela ngokwenqubo. Imingcele inikezwa ilebula yokufaka ipayipi.

6. Ukuhlolwa kwekhwalithi kagesioi-fusion pair interface

I-1) Ukuhlolwa kwekhwalithi ye-Weld : Indlela yokuhlola: ukuhlolwa okubonakalayo; Irula liyalinganiswa.

2)Hlola izinto: ukugxila; Qaphela ukuchichima impahla imbobo.

I-3) Imibandela yokufaneleka: ukuvulwa kwephutha kungaphansi kuka-10% wodonga lwamapayipi; Ukufakwa kwepayipi le-fusion kuhlanganiswe ngokuqinile nepayipi kanye nomfaniswano; Inqubo yokushisela ngaphandle kokubhema (ukushisa ngokweqile), ukuvala shaqa ngaphambi kwesikhathi; Imbobo yokubuka yokufakwa kwe-fuse iphuma kumpahla. Ukuhlangabezana nemibandela engenhla kungahlulelwa njengokufanelekile.

7.Izinyathelo zokuphepha

1) Ama-operators kufanele abe ingubo ephephile: gqoka amagilavu okuzivikela; Gqoka izicathulo zokusebenza; Gqoka izibuko zokuzivikela; (lapho ugaya ucezu lokusebenza) : ngama-earcups avikelayo, amakepisi wokushisela.

2) Izisetshenziswa ezisekelwe ngokuqinile, switch yokuvikela ukuvuza.
