Kufutfumeta ukhonkolo wire PNSV: isikimu emakhiyubhi yokuhlabelela

Kufutfumeta ukhonkolo PNSV wire ukubekwa isikimu okuzokwenziwa kuchaziwe ngezansi, isetshenziswa uma usebenza ngaphandle ebusika. manipulations ezinjalo kudingeka ngenxa yokuthi lapho ngaphansi lokushisa ongaphakeme isixazululo kancane iqala ukuba sithole amandla, kumane nje amanzi siqala ukushintsha sibe ice. ukuqina amade ngokhonkolo yokuthi umsebenzi yaqhubeka amasonto nezinyanga, ngaphezu, kukhona kungenzeka ukuthi design asisho ukuthola amandla efanele uzowa iyasebenza.

Isimiso ezisebenza we wire

wire ukhonkolo PNSV ubuchwepheshe efudumele itholakala lokuthi ukuthi ngaphambi kokuqala thusi ngamukela kudingekile ikhebula cross-section futhi ukucindezeleka kwaleso esibekiwe, esinguJesu bese wathela. Khona-ke intambo ixhunyiwe. Ungesabi ukuthi izinga ukhonkolo zizoshintsha ngaphansi kwethonya lokushisa eliphezulu, Bubbles awaveli njengoba imifantu ngemva kokuphulukisa, kodwa inqubo elapha ngeke ime okushisa aphansi, ezizohlinzeka design okuqinile futhi enokwethenjelwa.

Technical izici izintambo ngoba ukhonkolo

Wire Ukushisa ukhonkolo PNSV ngokuvamile inezici ezithile ezikhethekile. Lokhu umqhubi ngokuvamile zamanje aphethe, elithatha enamathela olubamba ukushisa. Isivikelo singenziwa ka-polyester noma polyvinyl chloride. Lapho ubukhulu kuyinto 1.2 mm, kodwa isilinganiso ukumelana okulingana 0.15 Ohm / m. Ungayisebenzisa etinhlotjeni letibanti lokushisa -60- + 50 ° C. Ngo ukusebenza, kungenzeka babe ilingana 14-16 amperes.

Ukubeka kungaba kwenziwe ngesikhathi -25- + 50 ° C. Ngaphambi kokuba uthenge udinga ukucacisa zizosetshenziswa bangaki izintambo, ukuze i-1 m ³ yesixazululo uzodinga cishe ngo-55 m.

Winter Ukushisa ukhonkolo ikhebula PNSV ephephile ngokuphelele, kusukela ukukhiqizwa umkhiqizo ithola ukwahlukanisa izinga ukuvimbela umlilo. Kukhona cishe akukho ngozi ukuthi nophilayo brokenfooted, njengoba anele. akufanele actuate bentambo nje ngeke kwamanzi ikhambi. Uma kungenjalo, ngeke zishe ngenxa zamanje anda. Nokho, iziphetho asesabi enye yezinto ezinjalo, ngoba akhiwa izintambo phezu umxhwele cross-section, ethula okuthiwa imikhawulo abandayo. Zenziwa kusukela APV-4, ubude esiphezulu 1 m.

Ububanzi bokusebenzisa

Izindlela amalahle ukhonkolo wire PNSV kuhilela ikhono lokusebenzisa nje ukubonisa yasekhaya, kodwa futhi ngezinga ezimbonini. Ngezinye izikhathi akhiqizwa ukufakwa

izisekelo kanye ezicijile.

Ukuqhuba ukufakwa ikhebula

Nokusingatha izintambo kusho handling wemfanelo. Ngaphambi kokuthi uqale inqubo laying, kubalulekile ukukhulula ebusweni doti futhi lezinto angaphandle osebenza kulabo izakhi ukuthi kungalimaza wire. Ngokuhamba lokhu kubalulekile ukuze kuqinisekiswe ukuthi ikhebuli akuyona insaliwe. Kunconywa ukuba afeze laying of a umkhumbi, kodwa akufanele kwakhiwa ezindaweni nalutho. Njengoba iningi elula ukustaka indlela izenzo inyoka.

Ngemva kokusebenzisa isidingo uqhubeke ngokuqaphela. Ngakho, kufanele kube khona izinguquko voltage, ukuze sifinyelele lo mgomo ufuna ukusebenzisa isimame, kungenjalo ngocingo nje zishe bese uyalikhipha ngeke kwenzeke.

uhlelo Warm wire ukhonkolo PNSV lapho isihloko. Uma nekuwusebentisa practice, wena ungaveza bese ugcwalisa uxhumano, okuhilela efingqa ikhebula kwamandla. Kunconywa ukuba isetshenziswe uma kuxhunywa transformer. Njengomthetho, ochwepheshe batusa ukusetshenziswa esiteshini Ukushisa imikhiqizo SPB-40, SPB-80.

Uxhumano angenziwa ezifundeni ezimbili kagesi, umshini wokuqala okuthiwa "inkanyezi", kanti eyesibili - a "unxantathu". Kulo mBhalo, izintambo ku wire zihlukaniswe izingxenye 3 alinganayo kanye wire ngamunye interfaced ngokulinganisa. Imisa kwakhiwa kumele exhunywe kwi-engeyokuqala 3 futhi uxhumeke kwi-terminals esiteshini 3rd.

Izici gaphambi

Ngaphambi kokuba uqale ngakho udinga ukwazi efudumele ukhonkolo wire PNSV.

Phakathi nenkathi lokuqala, ikhambi uzobe ukufuthelana, ngaleyo ndlela angamukelekile okwandisa izinga lokushisa okukhulu kuka-10 ⁰ C amahora amabili. Isikhathi sesibili akufanele ephelezelwa ukunyuka kwezinga lokushisa mkhulu kunezinhliziyo 80 ⁰ C. Ngesikhathi esigabeni sokugcina Ukupholisa ngomoya. Kulokhu, futhi, kufanele ungajahi nokuncipha akufanele bube ngaphezu kuka-5 ⁰ C ihora elilodwa.

Kufutfumeta ukhonkolo wire PNSV uhlelo kabani ukustaka okuchazwe lapha, sehlukile hhayi kakhulu kusukela obandayo uhlelo ubuchwepheshe "phansi efudumele". Ngaphezu kwalokho, lokhu ikhebula kungaba bazibandakanye ukufezekisa lezi zinjongo. Nokho, uhlelo kuyodingeka ukuqedela kancane, ukwakha heater izintambo we imicu, kanti phezulu kohlelo kumele ivikelwe ukwahlukanisa.

Izindleko Ukushisa ikhebula

Ngaphambi kokuba uthenge udinga uzijwayeze ikhebula amanani. Ezindaweni ezahlukene kungaba abiza ngezindlela ezahlukene, kodwa amanani isilinganiso uhlala ingashintshiwe, kuba elilingana ruble 2. / M. Akufanele ukuthenga umkhiqizo ngaphandle kokuhlola ngabe kulingana izindinganiso isimo, ngakho ikhebula ikhiqizwa ngokuvumelana nezindinganiso 12.1.013-78.

Ukuqhuba ukucutshungulwa ukhonkolo emva ukufudumala

abakhi Abaningi uyazibuza ukuthi kungenzeka ukuba bangasizakali ahlabayo noma imishini ukhonkolo ngemva ezuza amandla. Lo magazini kubangelwa yokuthi ngesikhathi kokuma design ukufudumala namanje akusho attain amandla banga. Phendula lo mbuzo uthambekele kokuhle, kodwa abanye ukubhuka. Sika, nakuba kungenzeka, kodwa Akwamukelekile ukukhiqiza ukushaqeka. Isixazululo esifaneleka kunazo zonke kuleli cala uba ukusetshenziswa amathuluzi idayimane. Ngakho, uma usebenzisa umsebenzi kulesi sigaba diamond imishini, emigodini ukhonkolo inzuzo imiphetho bushelelezi, nokusasamba ngeke kwenzeke. Ngaphezu kwalokho, uma ukuba bayamba umzimba eziphathekako ngokwenza kancane idayimane, bese uguqula ithuluzi ngesikhathi valve ekunqobeni akudingeki ukuthi esifanele ngokhonkolo njalo nakakhulu.

isazi izincomo

Kufutfumeta ukhonkolo isikimu PNSV wire laying okuyinto esihlokweni kungenziwa ezivezwa coiling yayo sokuqala luhlaka steel, ngakho-ke kuyadingeka ukuqinisekisa ukungabi khona ukungezwani. Ungakwazi umane walala phakathi izingxenye efulemini yensimbi. Kufanele kukhunjulwe ukuthi wire asisho uthinte kobuso formwork, aphume ashone kusukela umzimba ngokhonkolo ngemva kakhulu wawathela akufanele.

Ukushisa ikhebula ingafakwa kuphela ngemva kokwakhiwa uzimele ukuqinisa lwenziwe, akudingekile ukuqala ekuqhubeni le misebenzi futhi kuze kube isikhathi lapho izakhi esishunyekiwe ngeke uvele isikhala befaka isakhiwo. umsebenzi zokushisela Kufanele igcwaliswe sikhathi. Kufutfumeta ukhonkolo PNSV wire uhlelo kabani ukustaka iboniswa sibalo, akufanele uqhubeke ngemva kokuphulukisa isixazululo phakathi 50%.

Ukushisa lapho avela core kumele akwazi ukuxoxa ikhambi 40-800 ⁰ C. Period kuze kube uqweqwe lithola amandla egcwele, kuzoncika izici into, futhi ngokuvamile kuthatha cishe izinsuku ezintathu. Okufudumele esiteshini kumele kabusha usebenza kolayini esifushane noma eside. Isinyathelo phakathi izintambo akufanele bube ngaphezu kuka-15 mm.

wire ukhonkolo efudumele PNSV Ukubala okusesihlokweni esithi, kodwa ukuphoqelelwa yayo akukuniki yimpumelelo ephelele. Phela, kubalulekile ukuba acabangele ubuchwepheshe ukufakwa lapho kuhloswe ukuba ngakususi wire naye noma waliwela. Ukuze ukwazi ukulawula izinga lokushisa isixazululo kwezakhiwo enezikhukhula, kubalulekile ukwenza umgodi ekhethekile. Akufanele ziqale inqubo iyazifudumeza ukuba okwamanje kuze kube isixazululo selibekiwe ngokugcwele, ngoba kuphambene yezizathu zokuphepha, ngaphezu, kungalimaza wire. Kungcono ukuphathisa nokufezeka kwentando ezinjalo umsebenzi ochwepheshe, njengoba ukufakwa ikhebula kuhambisana nezinkinga ezithile futhi kudinga amakhono master ekuziphatheni manipulations ezinjalo.

Wire Ukushisa ukhonkolo ukubala

Uma sicabangela lokhu okungenhla, singathola waphetha kanje: 1 ^{m3 ngokhonkolo} kuyodingeka ichithe ama-55 metres ikhebula. Ukuze abale bentambo, kubalulekile ekuqaleni ukuthola kangakanani yesixazululo is batheleka formwork. Ngakho, i-20 m ³ ingxube kudingeka bathole 1100 m.

umsebenzi wokwakha Jikelele kungcono ukuba afeze phakathi nezinyanga zasehlobo, okuyinto kuyiqiniso ikakhulukazi Onjiniyela yangasese. Njengomthetho, ukugcinwa ethela aphathekako isikhathi abandayo kungenxa isidingo ukudlula into yesikhathi esithile. Umsebenzi onjalo ekwakhiweni ikhaya izindleko ezengeziwe for yokufuna emelana nokubanda enhlanzini yasezindaweni izithasiselo, Ukushisa izintambo kanye nezinye izinto. Yebo, kanye zabasebenzi ebusika lapho ukhonkolo kuthululwe kunzima kakhulu ngoba batch kuza njengoba ukusakazwa okwalandela ingxube ngokuvumelana formwork.
