Izintambo ezimelana nokushisa okuphansi (ezivame ukubizwa ngokuthi "izintambo ezingamelani nokubanda") ziwuhlobo lwezintambo ezikhethekile ezenzelwe izindawo ezishisa kakhulu. Ingqikithi yazo isekusetshenzisweni kwezinto ezikhethekile ezimelana nokushisa okuphansi, ezizivumela ukuthi zigcine izakhiwo zikagesi nezemishini ezinhle kakhulu ngisho nangaphansi kwezimo ezinzima kusukela ku--40°C kuya ku--60°C. Ngokuphambene nalokho, izintambo ezijwayelekile zibhekana nokonakala kokusebenza okusheshayo ezindaweni ezinjalo futhi azikwazi ukuqinisekisa ukusebenza okuphephile nokuthembekile.
1. Umehluko Oyisisekelo: Ukukhethwa Kwezinto Ezibalulekile
Izinto zokwakha ziyisici esiyinhloko esinquma ukumelana kwekhebula ekushiseni okuphansi, okubonakala kakhulu ekushiseni nasekuvaleni.
Izinto Zokuvala Ukushisa
Amakhebula Amelana Nokushisa Okuphansi: Sebenzisa izinto ezikhethekile zokushisa ezifana nama-fluoropolymers, i-Polyurethane (PU), i-PVC eguquliwe enokushisa okuphansi, kanye ne-Cross-Linked Polyethylene (XLPE) enokushisa okuphansi. Lezi zinto zinezakhiwo zama-molecule ezinokuguquguquka kokushisa okuphansi, okuqinisekisa ukuthi ungqimba lokushisa aluqhekeki noma lunciphe ngaphansi kwezimo ezibandayo kakhulu.
Amakhebula Ajwayelekile: Ngokuvamile asebenzisa i-PVC ejwayelekile nomaI-XLPE, eqina ngokushesha futhi iqhekeke emazingeni okushisa aphansi, okuholela ekwehlulekeni kokufakwa kokushisa.
Izinto Zokugoqa
Amakhebula Amelana Nokushisa Okuphansi: Igobolondo langaphandle livame ukusebenzisa i-Nitrile Rubber, i-Chloroprene Rubber (CR), i-EPDM, i-Thermoplastic Polyurethane (TPU), noma i-low-temperature eyakhelwe ngokukhethekile.Izinto ze-LSZHLezi zinto azigcini nje ngokumelana nokushisa okuphansi kodwa futhi zinikeza ukumelana okuhle kakhulu kokuguguleka, ukumelana nowoyela, ukumelana ne-UV, kanye nokumelana nesimo sezulu, okunikeza isivikelo esiphelele sekhebula.
Amakhebula Ajwayelekile: Igobolondo lenziwe kakhulu nge-PVC noma i-Polyethylene (PE) ejwayelekile, evame ukuguga nokuqhekeka ngaphansi kokucindezeleka okuhlangene kwamazinga okushisa aphansi kanye nezindawo eziyinkimbinkimbi, ilahlekelwa umsebenzi wayo wokuvikela.
2. Umehluko Wesakhiwo Nokusebenza
Ngokusekelwe ezimfanelweni zezinto ezibonakalayo, izinhlobo ezimbili zezintambo zibonisa umehluko omkhulu ekwakhiweni kwesakhiwo kanye nokusebenza kokugcina.
Umklamo Womqhubi Nokwakheka Kwesakhiwo
Amakhebula Amelana Nokushisa Okuphansi:
Umqhubi: Ngokuvamile usebenzisa izintambo zethusi ezinezintambo eziningi, ezicolekile kakhulu, ezihlanganiswe kahle ezingenawo umoya-mpilo noma izintambo zethusi ezifakwe emathinini, okuthuthukisa kakhulu ukuguquguquka kwekhebula kanye nokumelana nokushiswa kwe-oxidation.
Isakhiwo: Ubude bokubeka obuthuthukisiwe kanye nokwengezwa okungenzeka kwemicu yokuthamba, izendlalelo ezilwa nokusonta, noma izendlalelo ze-buffer ukuze kuthuthukiswe ukugoba, ukugoba, kanye nokumelana nokushayisana, okulungele ukusetshenziswa kokunyakaza.
Amakhebula Ajwayelekile: Isakhiwo senzelwe ukufakwa okungaguquki emazingeni okushisa ajwayelekile, ngokuguquguquka okuphansi kokugoba komqhubi kanye nokuqina okuncane kwemishini.
Ukuqhathaniswa Kokusebenza Okuyinhloko
Amakhebula Amelana Nokushisa Okuphansi:
Ukusebenza Komshini: Igcina ukuguquguquka okuphezulu, amandla aphezulu okudonseka, kanye nokumelana nokukhathala okugobile ngisho nasemakhazeni amakhulu.
Ukusebenza Kukagesi: Iyakwazi ukugcina ukumelana okuzinzile kokushisa kanye namazinga okumelana ne-voltage, kanye nokuqhuba kahle kakhulu.
Ukubekezelelana Kwemvelo: Ine-resistance evelele yokuguguleka, ukumelana nokugqwala kwamakhemikhali, kanye nokumelana nesimo sezulu.
Amakhebula Ajwayelekile:
Ukusebenza Komshini: Kulahlekelwa ukuguquguquka emazingeni okushisa aphansi; i-sheath kanye ne-insulation kulula ukuqhekeka, okwenza kube lula kakhulu ukulimala komshini.
Ukusebenza Kukagesi: Ukumelana nokushisa kwehla kakhulu, ingozi yokuphuka iyanda, okubeka izingozi ezinkulu zokuphepha.
3. Izimo Zokusebenza kanye Nokucatshangelwa Kwezomnotho
Umehluko wokusebenza unquma ngqo amasimu azo okusetshenziswa kanye nokusebenza kahle kwezomnotho.
Izimo Zohlelo Lokusebenza
Amakhebula Amelana Nokushisa Okuphansi: Ayindlela edingekayo ezindaweni ezifana nezindawo ezibandayo, izindawo zokugcina izinto ezibandayo zezimboni, izindawo eziphakeme kakhulu, amadekhi emikhumbi, amandla omoya angaphandle, imishini yolwandle olujulile, i-metallurgy, amakhemikhali kaphethroli, izindiza, kanye nocwaningo lwe-Antarctic.
Amakhebula Ajwayelekile: Afanelekela kuphela ukusatshalaliswa kwamandla angaphakathi, kanye nezakhiwo ezivamile zezimboni nezomphakathi ezindaweni zesimo sezulu esifudumele kanye nezinye izindawo zokushisa ezizungezile.
Ukufakwa Nokunakekelwa
Amakhebula Amelana Nokushisa Okuphansi: Aklanyelwe ukufakwa kokushisa okuphansi; kwezinye izimo, angasetshenziswa ngezinyathelo zokushisa kusengaphambili, anikeza ukulula kokufaka okuphezulu, ukuthembeka okuqinile kohlelo, kanye nemvamisa yokulungisa ephansi.
Amakhebula Ajwayelekile: Ukufakwa ezindaweni ezinokushisa okuphansi akuvunyelwe ngokuphelele, njengoba kungabangela kalula umonakalo ohlala njalo kungqimba lokuvikela, okuholela ezindleleni eziphezulu zokulungisa kamuva.
Ukuhlaziywa Kwezindleko
Amakhebula Amelana Nokushisa Okuphansi: Ngenxa yokusetshenziswa kwezinto ezikhethekile nezinqubo eziyinkimbinkimbi, izindleko zokuqala zokuthenga ziphakeme. Kodwa-ke, ngaphakathi kwendawo yazo eklanyelwe, zinikeza ukusebenza okuthembekile kanye nokuphila isikhathi eside kwenkonzo, okuholela ezindleko eziphansi zobunikazi.
Amakhebula Ajwayelekile: Anezindleko zokuqala eziphansi, kodwa uma esetshenziswa kabi ezindaweni ezinokushisa okuphansi, azoholela ekuhlulekeni okuvamile, isikhathi sokungasebenzi, kanye nezehlakalo zokuphepha, okuholela ezindleleni eziphezulu zezindleko.
Isifinyezo
Ukukhetha phakathi kwezintambo ezingamelani nokushisa okuphansi kanye nezintambo ezijwayelekile akusona isinqumo esilula esisekelwe kuphela ezindlekweni, kodwa isinqumo sobunjiniyela bezinhlelo esinqunywa ngokuyisisekelo yizimo zokushisa zendawo yokusetshenziswa. Ukukhetha okulungile kuyisidingo esiyinhloko sokuqinisekisa ukusebenza okuphephile, okuzinzile, kanye nesikhathi eside kwezinhlelo zamandla ezindaweni ezinokushisa okuphansi.
