- 1. Tchati cha kayendedwe ka njira
A. Ntchito Yokonzekera
B. Kulumikizana kwa ma elekitiroma
C. Kuyang'ana mawonekedwe
D. Ntchito yotsatira yomanga
2. Kukonzekera musanamange
1). Kukonzekera zojambula zomangira:
Kapangidwe kake mogwirizana ndi zojambula zomwe ziyenera kuchitika. Pamene kapangidwe kake kali ndi zojambula zogwira mtima, kapangidwe kake kayenera kupita kumalo omangirako kuti kamvetse momwe zinthu zilili. Pa gawo lomwe silingamangidwe malinga ndi zojambulazo, liyenera kuulula ndikukambirana ndi kapangidwe kake kuti lidziwe ngati ukadaulo wapadera womanga kapena kusintha kwa kapangidwe kake kungagwiritsidwe ntchito. Nthawi yomweyo, zipangizo ndi zida ziyenera kugulidwa malinga ndi zojambulazo, ndipo nthawi yomanga iyenera kukonzedwa.
2). Maphunziro a ogwira ntchito:
Ogwira ntchito yolumikiza mapaipi a gasi a polyethylene ayenera kulandira maphunziro apadera asanayambe ntchitoyo, ndipo angathe kuyamba ntchitoyo pokhapokha atapambana mayeso ndi kuwunika kwaukadaulo.
Kuwonjezera pa chidziwitso cha chiphunzitso cha chidziwitso cha mpweya, makhalidwe a zipangizo zapadera za polyethylene, chidziwitso chamagetsi, zida zowotcherera za polyethylene, ukadaulo womanga mapaipi a gasi a polyethylene ndi mbali zina za ogwira ntchito yophunzitsa, ndi kutenga nawo mbali mu kuwunika.
3). Kukonzekera makina ndi zida zomangira
Malinga ndi zofunikira za ukadaulo womanga, konzani makina ndi zida zomangira zoyenera. Popeza palibe muyezo wogwirizana wa khalidwe lolumikizira ndi magawo olumikizira mapaipi a polyethylene m'dziko lathu, magawo olumikizira mapaipi, zolumikizira mapaipi ndi valavu ya mpira wa PE yopangidwa ndi opanga osiyanasiyana ndi osiyana. Kuti mupeze zotsatira zodalirika zolumikizira, posankha zida ziyeneranso kusankhidwa mosamala, sankhani zinthu zabwino, mu zotsatira zolumikizira, kuti zikhale zodalirika.
a) Makina olumikizirana amagetsi okha
b) Jenereta ya dizilo ya 30Kw
c) Konzani chogwirira
d) Tembenuzani chokokera
e) Chokokera mbale
f) Chida cholumikizira
g) Zungulirani chodulira
h) Wolamulira wathyathyathya
i) Zizindikiro
3. Kulandira chitoliro, zolumikizira ndi valavu ya mpira wa PE
1) Yang'anani ngati zinthuzo zili ndi satifiketi ya fakitale ndi lipoti loyang'anira fakitale.
2） Yang'anani mawonekedwe. Yang'anani ngati mkati ndi kunja kwa chitolirocho ndi zoyera komanso zosalala, komanso ngati pali mipata, zojambula, mabowo, zinyalala ndi mitundu yosagwirizana.
3）Kuyang'ana kutalika. Kutalika kwa chubu kuyenera kukhala kofanana ndipo cholakwikacho sichiyenera kupitirira plus kapena minus 20 mm. Onani ngati kumapeto kwa chitoliro kuli kolunjika ku mzere wa chitoliro chimodzi ndi chimodzi, komanso ngati pali ma pores. Mapaipi a kutalika kosiyana sayenera kulandiridwa musanazindikire chifukwa chake.
4） Chitoliro cha polyethylene chogwiritsira ntchito mpweya chiyenera kukhala chachikasu ndi chakuda, chikada chakuda, pakamwa pa chitolirocho payenera kukhala ndi mzere wachikasu wokongola, nthawi yomweyo, payenera kukhala zizindikiro zokhazikika zosapitirira 2m, zomwe zikusonyeza cholinga chake, mtundu wa zinthu zopangira, chiŵerengero cha kukula koyenera, kukula kofunikira, nambala yokhazikika ndi nambala yotsatizana, dzina la wopanga kapena chizindikiro cha malonda, tsiku lopangira.
5）Kuyang'ana kuzungulira: Avereji ya masamu a zotsatira za mayeso a zitsanzo zitatu imatengedwa ngati kuzungulira kwa chitoliro, ndipo mtengo wake woposa 5% umaonedwa kuti ndi wosayenerera.
6） Yang'anani m'mimba mwake wa chitoliro ndi makulidwe a bi. M'mimba mwake wa chitolirocho uyenera kuyang'aniridwa ndi rula wozungulira, ndipo m'mimba mwake mbali zonse ziwiri uyenera kuyezedwa. Malo aliwonse osayenerera adzaonedwa ngati osayenerera.
Kuwunika makulidwe a khoma kumachitika ndi micrometer, kuyeza kuzungulira kwa mfundo zinayi zakumtunda ndi zakumunsi, iliyonse ndi yosayenerera.
7） Chitoliro, zolumikizira mapaipi, mayendedwe ndi kusungira ma valve a mpira wa PE
Kunyamula ndi kusunga zinthu za polyethylene kuyenera kuchitika m'njira izi: Chingwe chosakhala chachitsulo chiyenera kugwiritsidwa ntchito pomangirira ndi kukweza.
8） Osaponya ndipo mwa mphamvu yamphamvu, sayenera kukoka.
Siziyenera kukhudzidwa ndi dzuwa, mvula, mafuta, asidi, alkali, mchere, zinthu zogwira ntchito ndi mankhwala ena.
9) Chitoliro, zolumikizira, valavu ya mpira wa PE ziyenera kusungidwa pamalo opumira bwino, kutentha sikoposa 40℃, osachepera -5℃ m'nyumba yosungiramo zinthu, kuyika kwakanthawi pamalo omangira, kuyenera kuphimbidwa.
10) Pakunyamula ndi kusunga, chubu chaching'ono chikhoza kulowetsedwa mu chubu chachikulu.
11) mayendedwe ndi malo osungiramo zinthu ziyenera kuyikidwa mopingasa pansi panthaka ndipo garaja, ngati si yachibadwa, iyenera kukhazikitsidwa ngati malo ochiritsira, mtunda wa zothandizira ukhale 1-1.5m ndi woyenera, kutalika kwa mapaipi osapitirira 1.5m.
12) Akuti nthawi yosungira pakati pa kupanga ndi kugwiritsa ntchito isapitirire zaka ziwiri, ndipo mfundo ya "kulowa koyamba, kutuluka koyamba" iyenera kutsatiridwa pogawa zinthu.

4Masitepe olumikizira a electrokuwotcherera kosakanikirana
1). Lumikizani magetsi a gawo lililonse la chowotcherera. Muyenera kugwiritsa ntchito 220V, 50Hz AC, kusintha kwa magetsi mkati mwa ± 10%, magetsi ayenera kukhala waya wokhazikika; Konzani zida zothandizira monga cholembera, chotsukira chathyathyathya, cholamulira chathyathyathya, ndi chogwirizira chokonzera.
2） Konzani mapaipi ndi zolumikizira kuti zilumikizidwe, ndipo musatsegule phukusi la zolumikizira zolumikizira mwachangu kwambiri.
3） Kukhazikitsa katatu: chotsani phukusi lakunja la zolumikizira za mapaipi, zolumikizira za mapaipi zolembetsedwa mu zolumikizira za mapaipi kuti zilumikizidwe kuti zikhazikitse malo olembera; Ikani cholumikizira cholumikizira ndikukhazikitsa cholumikizira kuti chilumikizidwe ndi mipando; Tsegulani jekete la electrode la cholumikizira cha mapaipi ndikuyika electrode yotulutsa ya cholumikizira chamagetsi pa electrode yolumikizira mapaipi.
4) Gwiritsani ntchito makina olumikizirana motsatira njira yogwirira ntchito malinga ndi malo a magawo olumikizirana, pamanja (magawo operekedwa ndi chizindikiro cholumikizira chitoliro)
5) Yambitsani makina olumikizira magetsi kuti muyambe kugwiritsa ntchito makina olumikizira magetsi, ndipo makinawo adzazindikira kutentha kwa malo ozungulira ndikusintha magawo olumikizira magetsi. Ntchito yolumikizira magetsi ikatha, makinawo adzayimitsa nthawi yolumikizira magetsi ndi kuziziritsa. Kuziziritsa kutatha, maelekitirodi ndi chogwirira chokhazikika zitha kuchotsedwa kuti gawo lotsatira lizilumikizidwe.
6) Sindikizani mbiri ya njira yowotcherera kapena kusindikiza kwapakati komwe kumabwera pambuyo pake.
5. magawo a ndondomeko yowotcherera
Gwiritsani ntchito makina ochapira motsatira ndondomekoyi. Zofunikira zake zimaperekedwa ndi chizindikiro cholumikizira mapaipi.
6. Kuwunika khalidwe la electromawonekedwe a fusion pair
1) Kuyang'anira mawonekedwe a weld: Njira yowunikira: kuyang'anira ndi maso; Rula imayesedwa.
2) Chongani zinthu: kukhazikika; Yang'anani kuchuluka kwa zinthu zomwe zili m'dzenje.
3) Zofunikira: kutsegula cholakwika ndi kochepera 10% ya makulidwe a khoma la chitoliro; Cholumikizira chitoliro chosakanikirana chimaphatikizidwa bwino ndi chitoliro ndi chitolirocho; Njira yowotcherera popanda kusuta (kutentha kwambiri), kutseka msanga; Bowo lowonera la cholumikizira cha fuse limatuluka kuchokera kuzinthuzo. Kukwaniritsa zomwe zili pamwambapa kungawonedwe ngati koyenera.
7.Njira zodzitetezera
1) Ogwira ntchito ayenera kukhala otetezeka: kuvala magolovesi oteteza; Valani nsapato zogwirira ntchito; Valani magalasi oteteza; (mukamapera chogwirira ntchito): ndi makutu oteteza, zipewa zowotcherera.
2) Zipangizo zotchingira zolimba, zoteteza kutayikira.
CHANGRONGndi kampani yogwirizana ndi makampani ogulitsa magawo ndi malonda, yomwe idakhazikitsidwa mu 2005 yomwe imayang'ana kwambiri pakupanga Mapaipi a HDPE, Zolumikizira ndi Ma Vavu, Mapaipi a PPR, Zolumikizira ndi Ma Vavu, Zolumikizira ndi Ma Vavu a PP, komanso kugulitsa makina owetera mapaipi apulasitiki, Zida za mapaipi, Cholumikizira Chokonzera Mapaipi ndi zina zotero.
