Isakhiwo
Ikhebula elixhumene nesiphambano lakhiwa umgodla wangaphandle, izikhali zensimbi, igobolondo langaphakathi, isigcwalisi, isendlalelo sokuvikela ithusi, ungqimba lwe-semiconducting yangaphandle, ungqimba oluvikelayo, ungqimba lwe-semiconducting yangaphakathi, umqhubi, umgogodla wemali wekhebula.Ngakho-ke, hlobo luni lwesakhiwo sekhebula esidinga ukuthi yiluphi uhlobo lwezinto ezibonakalayo nobuchwepheshe bezesekeli zekhebula kanye nokuxhumana kwayo okukodwa nokuhambisana.
Isimiso sokuklama sokuhlanganisa ikhebula kufanele sihlangabezane futhi sifinyelele izidingo: yenza ikhebula lisebenze ngokuphepha kunoma iyiphi indawo yemvelo.Ukuze kuzuzwe lokhu, kudingekile ukunaka izici ezine ezibalulekile, okuyilezi: (1) ukubekwa uphawu, (2) ukwahlukanisa, (3) insimu kagesi, (4) inqubo nezinye izakhi.Lokhu futhi ukuxazulula izinkinga ezine ezibalulekile zekhanda lekhebula.
Kuvaliwe
1) Ngoba iningi lamajoyinti ekhebula afakwe emigqeni yangaphandle, ngaphansi komhlaba nezinye izindawo.Ngakho-ke, ukuvimbela amanzi kanye nomswakama-umswakama kube yinye yezihluthulelo zokuqinisekisa ukusebenza okuphephile kwamalunga ekhebula.Futhi ukusebenza kwayo kokubeka uphawu nezindlela kufanele kucatshangelwe.
Njengamanje, kunezindlela ezimbili zokufaka uphawu:
1. enye iyindlela yokubumba nge-asphalt noma i-epoxy resin.Le ndlela iyinkimbinkimbi ngenqubo, kunzima ukuyilawula, futhi ayihambisani nokugcinwa.
2. Enye indlela entsha, okwamanje okuyindlela ekhethwayo yabakhiqizi basekhaya nabangaphandle, ukusebenzisa ama-sealant anwebeka kakhulu.Inqubo ilula, ukusebenza kunokwethenjelwa, futhi ukugcinwa nokufakwa kulula.Lezi zinzuzo eziyingqayizivele ziyenza ibe inkambi yokusetshenziswa.
Ukuze usebenzise le ndlela entsha, into yokuqala okufanele uyicabangele ukusebenza kwe-sealant.Ngoba ikhwalithi nokusebenza kwe-sealant kuthinta ngokuqondile ukusebenza kokuvala kwe-cable joint.Khetha i-glue engakwazi ukuhlangana nobuso bomzimba wekhebula kanye nobuso bezinto ezitholakalayo ngokuqinile.Ngesikhathi esifanayo, kubaluleke kakhulu ukukwazi ukuhlangabezana neglue engasetshenziswa ezindaweni ezihlukahlukene zokushintsha izinga lokushisa.
2) Ngoba izesekeli zekhebula lamandla abandayo-shrinkable ngokugcwele ziyizisekeli zekhebula elinwebekayo.Okusho ukuthi, ukunwebeka kwerabha ye-silicone ewuketshezi isetshenziselwa ukwandisa ipulasitiki kanye nemicu yokusekela efektri kusengaphambili.Ibeke endaweni ebekiwe khona lapho, bese ukhipha ibha yokusekela ukuze uyishwabanise ngokwemvelo.Lolu hlobo lobuchwepheshe ubuchwepheshe bokushwabana obubandayo, futhi lolu hlobo lwesisekeli luyisisetshenziswa sekhebula esinciphayo esibandayo.Ngakho-ke, lesi sisekeli esibandayo esinciphayo sine "elasticity" enhle.Ingagwema ukunwetshwa okushisayo nokufinyezwa kwekhebula ngenxa yemvelo yomoya kanye nezinga lomthwalo ngesikhathi sokusebenza kwekhebula.Kuyingozi yokuphuka edalwe igebe phakathi kwe-insulation ekhiqizwa "ukuphefumula kwekhebula".Ukungalungi okukhulu kwezesekeli ezikwazi ukushisa ukushisa ukuthi aziguquki.Ngakho-ke, izesekeli ezikwazi ukushwabana ezibandayo ngokuphelele ziyizinqumo ezingcono kakhulu ezingasetshenziswa ezindaweni ezinomehluko omkhulu wokushisa kanye nomthelela omkhulu wesimo sezulu.
I-Insulation
Isidingo sokwahlukanisa sekhanda lekhebula ukuhlangabezana nezinto ezimbili eziyinhloko zokwahlukanisa kwesigaba nesigaba kanye nomhlabathi ophambene.
1. I-insulation yesigaba-kuya-isigaba yizinhlobo ezimbili zezinto zokufakelwa: uhlobo lwerabha ye-silicone kanye nezinto ezishiswayo.Ngokuvamile, ukusebenza kwe-insulation kudinga ukuhlangabezana nezidingo ezisekelwe kunkomba yokufaka iyunithi yento ehlanganiswe nobukhulu bento.
2. I-insulation phakathi kwesigaba kuya phansi ukuvimbela ukushaja ekukhuphukeni ibanga eliphephile ukusuka kumandla aphezulu kuya emandleni aphansi.Izinto zenjoloba ye-silicone ebandayo eshwabene inokunwebeka okuhle.Uma nje umklamo unengqondo, ukuqina kwawo okuqinile kunamandla okwanele okubamba.Izinga lokushisa elinciphayo lekhanda lekhebula elishwabenekayo lingu-100℃-140℃, futhi izinga lokushisa lingahlangabezana nezimo zalo zokuncipha kuphela lapho lifakiwe.Uma izinga lokushisa liphansi, ngenxa yokuthi i-thermal expansion coefficient yekhebula ihlukile kuleyo yezinto ezishwabenekayo, kungenzeka ukuthi i-delamination izokwenzeka endaweni engaphansi kuka-80 ℃, ngakho-ke kuzovela imifantu.Ngale ndlela, amanzi nomswakama kuzongena ngaphansi kwesenzo sokuphefumula, ngaleyo ndlela kucekele phansi ukufakwa kwesistimu.Kodwa-ke, lapho izimo zemvelo zishintsha, akukho ukunwebeka okufana nerabha ye-silicone, ngakho-ke kuzothinta nokuphepha.Lokhu kuwububi bezinto ezincipha ukushisa.
Inkundla kagesi
Inkambu kagesi yezihlanganisi zekhebula ezibandayo ezibandayo ziphathwa ngendlela yejometri, eshintsha ukusabalalisa insimu kagesi ngokusebenzisa ikhoni yokucindezeleka.Ixazululwa ngomumo othile wejometri kanye ne-engeli engu-R enembile.Le ndlela kulula ukuyilawula nokuhlola.Kungaqinisekiswa futhi kubonakale efektri.Indlela yokwelapha insimu kagesi yekhanda lekhebula elishwabene ukushisa iwukushintsha ukusatshalaliswa kwensimu kagesi ngendlela yepharamitha ewumugqa.Kumele ithembele kumapharamitha amabili abalulekile: ukumelana nevolumu, i-108-11Ω, kanye ne-b dielectric constant ye-25. Ngenxa yenqubo yayo yokukhiqiza eyinkimbinkimbi kanye nezinguquko ezinkulu ngenxa yezici zemvelo, kunzima ukulawula ukuzinza kwemingcele.Ngakho-ke, kuzoba nomthelela kwikhwalithi yomkhiqizo.
Ukukhetha ukunqanyulwa kwekhebula okuhle kakhulu noma amajoyinti ephrojekthi akufanele neze kuqatshelwe.Ukunqanyulwa kwekhebula lakho maduzane kuzoba ingxenye ebalulekile yokusebenza kwakho.Awukwazi ukukhokhela ingxenye yebhizinisi evaliwe ngenxa yokulungiswa njalo noma ukuwohloka.Imikhiqizo yokunqanyulwa kwekhebula ebandayo elungile / yokunciphisa ukushisa izokhuphula umkhiqizo wakho futhi yenze umsebenzi ube lula kakhulu kubasebenzi.Vele uqiniseke ukuthi wenza ucwaningo olufanele ukuze ukhethe ukunqanyulwa kwekhebula okusingatha yonke imisebenzi yakho, okunikeza isevisi ethembekile, futhi abasebenzi bakho baqeqeshwe ngendlela efanele.
