Ipayipi lepompo yokushisa yomthombo womhlaba we-PE
Izici zomkhiqizo
Ipayipi linezici zamakhemikhali ezizinzile futhi alikwazi ukugqwala, okuhlanganisa ukushiyeka okukhulu kwamapayipi ensimbi kulokhu;
Kulula ukugoba noma ukuncibilikisa ukuze kwakheke isimo esiqinile, futhi inokumelana okunamandla kwengcindezi uma ixhunywe ku-fittings yamapayipi, futhi akulula ukubangela ukuvuza; ukusebenza kokushintshana kokushisa kuhlangabezana nezidingo zokushintshana kokushisa, izindleko ziphansi, futhi ukwakhiwa kulula;
Impilo yesevisi ingafinyelela eminyakeni engaphezu kwengu-50.
Ukusebenza okuphezulu kakhulu
Ipayipi elihle akufanele libe nokusebenza kahle kwezomnotho kuphela, kodwa futhi libe nochungechunge lwezinzuzo ezifana nezixhumi ezizinzile nezithembekile, ukumelana nezinto ezithintekayo, ukuqhekeka, ukuguga nokugqwala. Uma kuqhathaniswa namapayipi endabuko, uhlelo lwepayipi le-HDPE lunezinzuzo ezilandelayo:
Ukusebenza kokuxhumeka okuthembekile
Ukumelana okuhle komthelela
Ukumelana okuhle kokuqhekeka kokucindezeleka
Ukumelana okuhle kakhulu kokugqwala
Ukumelana okuhle kakhulu kokugqokwa
Impilo yenkonzo ende
Ukuguquguquka okuhle
Ukusebenza kahle kokuhlanzeka
Ukumelana nokugeleza kwamanzi okuphansi

Ukufakwa
1. Ukufakwa kwezisekelo ezincibilika ngokushisa. Le ndlela ivame ukusetshenziswa ezinhlotsheni ze-DN20-DN110mm. Inqubo ethile yokusebenza imi kanje:
(1) Sebenzisa izikere zamapayipi ukusika ipayipi ngokwezidingo zokufakwa;
(2) Maka ukujula kwepayipi elizofakwa;
(3) Shisisa i-hot melter ku-210℃
(4) Shisisa amapayipi kanye nezinto zokufaka ngesikhathi esisodwa, bese ufaka amasokhethi (linda isikhashana ngemva kokuba amasokhethi esesendaweni bese uwadedela. Ungahambi ngesikhathi senqubo yokushisa, yokufaka amasokhethi kanye nokupholisa)
(5) Kupholile ngokwemvelo:
(6) Ngemva kokuba ukwakhiwa sekuqediwe, ipayipi lingavalwa futhi lisetshenziswe kuphela ngemva kokudlula ukuhlolwa kokucindezela.
2. Ukufakwa kwe-Hot-melt butt, imininingwane ye-DN160-DN1200mm ngokuvamile isebenzisa le ndlela, imisebenzi elandelayo:
(1) Beka amapayipi amabili e-PE azoxhunywa ku-hot melt fixture ngesikhathi esisodwa (i-clamp ingashintshwa ngokuya ngobubanzi bepayipi elizofakwa), bese uphakamisa olunye uhlangothi lwepayipi ngalinye endaweni efanayo yamanzi nge-bracket yepayipi;
(2) Sebenzisa umshini wokusika kagesi ukusika ubuso bokugcina bamapayipi bube yisicaba ukuqinisekisa ukuthi ubuso bokuxhumana bamapayipi amabili bungalingana ngokugcwele
(3) Phakamisa ipuleti lokushisa likagesi libe ngama-degree angu-210, ulibeke phakathi kwezinhlangothi ezimbili zamapayipi, bese usebenzisa idivayisi kagesi ye-hydraulic ukuze wenze izinhlangothi ezimbili zamapayipi zixhumane ngokuphelele futhi zifudumale nepuleti lokushisa likagesi ngesikhathi esisodwa;
(4) Susa ipuleti lokushisa bese usebenzisa idivayisi ye-hydraulic futhi ukuze wenze iziphetho ezimbili zamapayipi ancibilikisiwe ziqine ngokuphelele bese zikhiya idivayisi ye-hydraulic (ukuvimbela ukubuyela emuva);
(5) Yigcine isikhathi esithile sokupholisa bese uyikhulula, bese umsebenzi usuqediwe;
(6) Ngemva kokuba ukwakhiwa sekuqediwe, kumele kudlule ukuhlolwa kokucindezela ngaphambi kokuba kugqitshwe futhi kusetshenziswe; (Qaphela: Ukuhlolwa kokucindezela kumele kube ukuhlolwa kokucindezela koketshezi!)
(7) Thatha izinyathelo ezingangeni moya ngesikhathi senqubo yokushisa ipayipi, futhi ngesikhathi senqubo yokupholisa, ipayipi kufanele ipholiswe kancane kancane esikhundleni sokuphola ngokushesha.
3. Ukuxhumeka kwe-fusion kagesi (ububanzi bepayipi obusebenzayo dn≤630mm):
(1) Faka ipayipi le-PE ngokuphelele endaweni yokuhlanganisa ipayipi kagesi;
(2) Xhuma izintambo ezimbili zomshini okhethekile wokuhlanganisa kagesi ezigxotsheni ezinhle nezimbi zomshini wokuhlanganisa kagesi ngokulandelana;
(3) Vula amandla okushisa ucingo lokushisa ukuze uncibilikise i-PE lapho kuxhumana kwangaphakathi;
(4) Ngemva kokupholisa:
(5) Ngemva kokuba ukwakhiwa sekuqediwe, kumele kudlule ukuhlolwa kokucindezela ngaphambi kokuba ipayipi livalwe futhi lisetshenziswe.
4. Ukuxhumeka kwe-Flange
5. Ukuxhumeka kwebhodwe nepulasitiki
6. Ukufakwa kwedokodo elimise okwesihlalo, okusebenza kahle kakhulu ekuxazululeni inkinga yokuphambuka kwepayipi eliyinhloko
