Ubungcali kwiintambo zangaphantsi

1. Yintoni intambo yamanzi?
Iintambo ezinokusetyenziswa ngokwesiqhelo emanzini zibizwa ngokuba ziintambo zamanzi (amanzi amaninzi). Xa intambo ilala phantsi kwamanzi, ihlala imbizwa emanzini okanye kwiindawo ezimanzi, intambo iyadingeka ukuba ifumaneke kwintambo, ngenxa yokuthintela intambo, kwaye iqinisekise ukusebenza kwexesha elide kwintambo. Imodeli ye-proby ye-jebs, eyinxalenye yerabha yerabha yerabha, intambo yamanzi eyahlulelene nentambo yamanzi e-FSPOF kunye ne-HOSPY, i-FS-DJYP3.

I-2. Uhlobo lwentambo ye-waterproof yentambo
(1). I-carbs engatshatanga enye, esongelayoI-SEMi-PHEAMIKI YENDLELA YOKUZIPHATHAKwikhathuni le-insulan, esonga iqhelekileyoIteyiphu yokuthintela amanziNgaphandle, emva koko tyhala i-sheath engaphandle, ukuze kuqinisekiswe ukuba unxibelelwano olupheleleyo lwekhaka lentsimbi, lisonga nje i-tepes ye-teping thessing, i-field yentsimbi engasasebenziyo i-filler ye-filler okanye ibhloko yentsimbi inokugcwaliswa. I-Line yeLizwe engaphakathi kunye ne-Sheath Sheath Sheath iyafana nezo zichazwe kwintambo enye ye-core.

(2). I-Aluminum ye-Aluminum ye-Aluminum ye-Aluminum ye-Aluminum ye-ALUMUCIFUCIFINIFUCMNIFORINGRED itshekishwe ngaphakathi kwi-sheath okanye i-laker ye-inile yangaphakathi njengokungqinelana kwamanzi.

(3). Phambili i-HDPE i-HDEP engaphandle ngqo kwintambo. Intambo ye-XPE ifakwe intambo engaphezulu kwe-110kv ixhotywe nge-sheath yensimbi yokuhlangabezana neemfuno zamanzi. Ikhaka lesinyithi ligqibe kakhulu kunye nokunganyangeki kwamanzi okuhle kwamanzi. Iindidi eziphambili ze-sheath yensimbi zezi: I-Aluminium evinjwe i-Aluminium ye-Aluminium, eshushu icinezelekile ye-Aluminum ye-Aluminum ye-Aluminum, ye-Weldigaum ye-WelDed Steed, i-WelDed Steed Deleve, kunjalo.

I-3. Ifom yamanzi yentambo yamanzi
Ngokubanzi yahlulwe yaba liqela elithe nkqo kunye nenkunkuma. Ukuchasana kwamanzi athe nkqo kusetyenziswaibhloko yamanzi evaliweyo, umgubo wamanzi kunye neendlela zamanzi zokuvimba amanzi, indlela yokuxhathisa kwamanzi kwezi zixhobo zinamanzi anokwandisa intambo, ukuze kufezekiswe intambo yentambo ixesha elide. Ukuxhathisa amanzi e-radicy ikakhulu ngokukhuphela i-HDPE ye-HDPE ye-HDPE okanye ukucofa i-sheet, i-welding kunye ne-sheath yensimbi yensimbi.

I-4. Ukuhlelwa kweentambo zamanzi
Zintathu iindidi ezintathu zeentambo zamanzi ezisetyenziswa eTshayina:
(1). Intambo ye-Inript yephepha eliyi-oyile yeyona intambo ephindiweyo yamanzi enganyangekiyo. Ukufakelwa kwayo nabaqhubi bazaliswe yi-oyile yentambo, kwaye kukho i-jacket yentsimbi (ijacket yentsimbi okanye i-aluminium jacket) ngaphandle kwe-inshontes, eyintambo yokuchasana namanzi. Kwixa elidlulileyo, uninzi lwamanqanaba aphantsi komhlaba (okanye ngaphantsi kwamanzi) Iintambo ezisetyenzisiweyo ze-oil, kodwa iikhabhathi zeoyile zinqongophele, kwaye kukho ingxaki ekuvuyisweni kweoyile, kwaye ngoku zisetyenziswa kancinci kwaye zincinci.

(2). Imigca yerabha ye-Ethyylene proplene yerabha isetyenziswe ngokubanzi kwimigca yokuhambisa amanzi aphantsi kwaye ephakathi ye-Delewater ePhakamileyo yentsebenzo yokufakelwa ngaphandle kwexhala 'lomthi wamanzi ". Intambo yerabha yerabha yamanzi (uhlobo lwe-JHS) inokusebenza ngokukhuselekileyo kumanzi angaphantsi kwexesha elide.

(3). I-Polythylene edibeneyo ye-Polythylene (i-XPE) inyathelo lamandla e-incoring ngenxa yombane ocacileyo, kunye nenkqubo yokufakelwa kwemveliso, ngaphandle kwenkqubo yokungafuneki, i-Proney Rownlownlown engasebenziyo, Ukunciphisa ubomi benkonzo yentambo. Ke ngoko, intambo ye-Polythylene inxibelelene, ingakumbi intambo ye-voltium kunye ne-voltage ye-voltage phantsi kwesenzo sombane we-AC, kufuneka sibe nesakhiwo se-Clotage, kufuneka sibe nendawo esetyenziswayo "kwindawo emanzi.

5. Umahluko phakathi kwentambo yamanzi kunye nentambo yesiqhelo
Umahluko phakathi kweentambo zamanzi kunye neentambo eziqhelekileyo kukuba iintambo eziqhelekileyo azinakusetyenziswa emanzini. Intambo ye-JHS Androof ikwanohlobo lwentambo eguqukayo yerabha, i-inshuler irhasi yerabha, kunye nentambo yerabha yesiqhelo, intambo ye-JHS idla ngokusetyenziswa, kodwa kudlula emanzini. Iintambo zaManzi ze-Aterproof zihlala zi-3, uninzi lwazo lusetyenziswa xa uqhagamshela impompo, ixabiso leentambo zerabha ziya kubiza i-ruble yerabha, kuya kufuneka unxibelelane nomthengisi ukuba wazi ungqimba lwamanzi.

I-6. Umahluko phakathi kwentambo ye-waterproof kunye nentambo yamanzi enganyangekiyo
Intambo yaManzi ye-Waterproof: Thintela amanzi ukuba angangeni kwi-Inriorme ye-Cable, usebenzisa isakhiwo sentambo kunye nezixhobo.

Intambo yokubhloka amanzi: Uvavanyo luvumela amanzi ukuba angene kwi-leble yentambo, kwaye akavumeli ukungena kwi-Penetions ukuya kubude obuchaziweyo. Intambo yokuvala amanzi yahlulahlulwe yanguManzi weCloctor amanzi kunye nentambo engumbane.

Ubume bolonga lwamanzi omqhubi: ukongeza i-powder ye-valter kunye ne-varn yokuthintela i-wire ye-wire, xa umqhubi efaka amanzi, apho amanzi avelisa amanzi anendawo yokuthintela ukungena kwamanzi okusebenzayo.

Isakhiwo sokubhloka kwamanzi sentambo Xa amanzi evaliwe ayanda, ikhawuleza aqonde icandelo lokubhloka kwamanzi ukuthintela ukungena kwamanzi. Kwikhabhathi ye-on-cobre ezintathu, kunzima kakhulu ukufezekisa intambo yekhebula elipheleleyo, kuba isikhewu esiphakathi se-core esineempawu ezibini sizaliswe, nokuba i-cont yebhloko yamanzi igcwaliswe ngokwesiseko se-char-quation, kwaye ke intambo yenziwa.
