Izixhobo zeCable zokuVimba amanzi
Izinto zokuvimba amanzi ngokubanzi zingahlulwahlulwa zibe ziindidi ezimbini: ukuvimba amanzi okusebenzayo kunye nokuvimba amanzi okungasetyenziswayo. Ukuvimba amanzi okusebenzayo kusebenzisa iimpawu zokufunxa amanzi nokudumba kwezinto ezisebenzayo. Xa isheya okanye ilungu lonakele, ezi zinto ziyanda xa zidibana namanzi, zinciphise ukungena kwawo ngaphakathi kwintambo. Ezi zinto ziqukaijeli ekhulayo efunxa amanzi, iteyiphu yokuvimba amanzi, umgubo wokuvimba amanzi,intambo yokuvala amanzi, kunye nentambo yokuvala amanzi. Kwelinye icala, ukuvala amanzi okungasebenziyo kusebenzisa izinto ezithintela amanzi ngaphandle kwentambo xa isheya yonakele. Imizekelo yezinto ezithintela amanzi okungasebenziyo yintlama egcwele ipetroli, iglu enyibilikayo eshushu, kunye nentlama ekhulisa ubushushu.
I. Izinto zokuVimba amanzi ezingasebenziyo
Ukuzaliswa kwezinto ezithintela amanzi, ezifana nepetroleum paste, kwiintambo yayiyeyona ndlela iphambili yokuvala amanzi kwiintambo zamandla zokuqala. Le ndlela ithintela amanzi ukuba angangeni kwintambo kodwa ineengxaki ezilandelayo:
1.Iyandisa kakhulu ubunzima bentambo;
2.Ibangela ukwehla kokusebenza kwentambo yokuqhuba umbane;
3. Ipeyinti yepetroliyam ingcolisa kakhulu iintambo, nto leyo eyenza ukucoca kube nzima;
4. Inkqubo yokuzalisa epheleleyo kunzima ukuyilawula, kwaye ukuzalisa okungaphelelanga kunokubangela ukusebenza kakubi kokuvala amanzi.
II. Izinto Zokuthintela Amanzi Ezisebenzayo
Okwangoku, izinto ezithintela amanzi ezisebenzayo ezisetyenziswa kwiintambo ikakhulu yiteyiphu yokuthintela amanzi, umgubo wokuthintela amanzi, intambo yokuthintela amanzi, kunye nentambo yokuthintela amanzi. Xa kuthelekiswa nepetroleum paste, izinto ezithintela amanzi ezisebenzayo zineempawu ezilandelayo: ukufunxwa kwamanzi okuphezulu kunye nesantya esiphezulu sokudumba. Zinokufunxa amanzi ngokukhawuleza kwaye zidumbe ngokukhawuleza ukuze zenze into efana nejeli ethintela ukungena kwamanzi, ngaloo ndlela iqinisekisa ukhuseleko lobushushu bentambo. Ukongeza, izinto ezithintela amanzi ezisebenzayo zilula, zicocekile, kwaye kulula ukuzifaka nokuzidibanisa. Nangona kunjalo, zikwanazo nezinye iingxaki:
1. Umgubo ovimba amanzi kunzima ukuwuncamathisela ngokulinganayo;
2. Iteyiphu okanye uboya obuthintela amanzi bunokunyusa ububanzi bangaphandle, buthintele ukusasazwa kobushushu, bukhawulezise ukuguga kobushushu bentambo, kwaye bunciphise amandla okuhambisa intambo;
3. Izinto ezithintela amanzi ezisebenzayo zibiza kakhulu ngokubanzi.
Uhlalutyo lokuVimba Amanzi: Okwangoku, indlela ephambili eTshayina yokuthintela amanzi ukuba angangeni kumaleko wokugquma kweentambo kukwandisa umaleko ongangeni manzi. Nangona kunjalo, ukuze sifezekise ukuvinjwa kwamanzi okubanzi kwiintambo, akufuneki siqwalasele kuphela ukungena kwamanzi ngemitha kodwa sikwathintele ngokufanelekileyo ukusasazeka kwamanzi ixesha elide xa engena kwintambo.
Umaleko Wokwahlukanisa Amanzi wePolyethylene (Inner Sheath): Ukukhupha umaleko wokuvala amanzi we-polyethylene, kunye nomaleko womqamelo ofunxa umswakama (njengeteyipu yokuvala amanzi), kunokuhlangabezana neemfuno zokuvala amanzi ixesha elide kunye nokukhuselwa komswakama kwiintambo ezifakwe kwiindawo ezimanzi ngokulinganayo. Umaleko wokuvala amanzi we-polyethylene kulula ukuwenza kwaye awudingi zixhobo ezongezelelweyo.
Itheyiphu yeAluminiyam eQokelelwe ngePlastiki Itheyiphu yePolyethylene eQokelelwe ngePolyethylene Ulwelo lokuZihlukanisa olungangeni manzi: Ukuba iintambo zifakelwe emanzini okanye kwiindawo ezimanzi kakhulu, amandla okuvimba amanzi e-radial yeeleya zokwahlula i-polyethylene anganelanga. Kwiintambo ezifuna ukusebenza okuphezulu kokuvala amanzi e-radial, ngoku kuqhelekile ukusonga umaleko wetheyiphu ye-aluminium-plastiki edibeneyo ujikeleze umongo wentambo. Olu tywino lunamandla amakhulu okanye amawaka okumelana namanzi kune-polyethylene ecocekileyo. Lo gama nje umthungo wetheyiphu edibeneyo ubotshelelwe ngokupheleleyo kwaye uvaliwe, ukungena kwamanzi akunakwenzeka. Itheyiphu edibeneyo ye-aluminium-plastiki ifuna inkqubo yokusonga nokubopha ende, ebandakanya utyalo-mali olongezelelweyo kunye nohlengahlengiso lwezixhobo.
Kwimisebenzi yobunjineli, ukufikelela ekuvalekeni kwamanzi okude kuyinkimbinkimbi ngakumbi kunokuthintela amanzi okude. Iindlela ezahlukeneyo, ezinje ngokutshintsha isakhiwo se-conductor sibe yi-tight-pressed design, zisetyenzisiwe, kodwa iziphumo bezincinci kuba kusekho izikhewu kwi-conductor ecinezelweyo evumela amanzi ukuba asasazeke ngesenzo se-capillary. Ukuze kufikelelwe ekuvalekeni kwamanzi okude, kuyimfuneko ukugcwalisa izikhewu kwi-stranded conductor ngezinto zokuthintela amanzi. La manqanaba mabini alandelayo okulinganisa kunye nezakhiwo zingasetyenziselwa ukufikelela ekuvalekeni kwamanzi okude kwiintambo:
1.Ukusetyenziswa kwee-conductors ezivala amanzi. Yongeza intambo evala amanzi, umgubo ovala amanzi, intambo evala amanzi, okanye ubophe iteyiphu evala amanzi ujikeleze i-conductor ecinezelwe ngokuqinileyo.
2.Ukusetyenziswa kwee-cores ezivimba amanzi. Ngexesha lenkqubo yokwenziwa kweentambo, gcwalisa umbindi ngentambo evimba amanzi, okanye ugqume umbindi ngeteyipu ethintela amanzi ecothayo okanye ekhusela ubushushu.
Okwangoku, umceli mngeni ophambili ekuthinteleni amanzi ixesha elide usekwe kwiikhondektha ezithintela amanzi—indlela yokuzalisa izinto ezithintela amanzi phakathi kweekhondektha kunye nezinto ezithintela amanzi ekufuneka zisetyenziswe iseyeyona nto iphambili kuphando.
Ⅲ. Isiphelo
Itekhnoloji yokuthintela amanzi ngemitha isebenzisa ikakhulu iileya zokuthintela amanzi ezijikeleze umaleko wokukhusela we-conductor, kunye nomgangatho womqamelo ofunxa umswakama ongezelelweyo ngaphandle. Kwiintambo ze-voltage ephakathi, iteyiphu edibeneyo ye-aluminium-plastiki isetyenziswa rhoqo, ngelixa iintambo ze-voltage ephezulu zihlala zisebenzisa ijekethi zokutywina zentsimbi ye-lead, i-aluminium, okanye i-stainless steel.
Itekhnoloji yokuvimba amanzi ende igxile kakhulu ekuzaliseni izikhewu phakathi kwemicu eqhubayo ngezinto zokuvimba amanzi ukuthintela ukusasazeka kwamanzi embindini. Ukususela kuphuhliso lwangoku lwetekhnoloji, ukuzalisa ngepowder yokuvimba amanzi kusebenza kakuhle ekuvaleleni amanzi ende.
Ukufikelela kwiintambo ezingangeni manzi kuya kuchaphazela ngokuqinisekileyo ukuchithwa kobushushu kweentambo kunye nokusebenza kokuhambisa umbane, ngoko ke kubalulekile ukukhetha okanye ukuyila ulwakhiwo olufanelekileyo lweentambo ezithintela amanzi ngokusekelwe kwiimfuno zobunjineli.
