Ukusetyenziswa kweteyiphu yokufudumeza kwi-antifreeze kunye ne-thermal insulation of subway

Ngokukhawuleza kokufudukela ezidolophini, uloliwe ohamba ngaphantsi komhlaba, njengesithuthi sikawonke-wonke esisebenzayo nesifanelekileyo, udlala indima ebalulekileyo kuthutho lwasezidolophini. Nangona kunjalo, imibhobho, izixhobo kunye nezixhobo kwi-subway system ziyakwazi ukukhenkceza kwiindawo eziphantsi kweqondo lokushisa ebusika, okukhokelela ekungaphumeleli kunye neengozi zokhuseleko. Ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwendlela kaloliwe engaphantsi komhlaba, amanyathelo asebenzayo okuthintela umkhenkce kunye nokugcina ubushushu kufuneka athathwe. Iteyiphu yokufudumeza isetyenziswe ngokubanzi kwindlela engaphantsi kwendlela yokugquma umkhenkce.

Iteyiphu yokufudumeza yinto yokufakelwa kwe-thermal esebenzisa amandla ombane ukwenza ubushushu. Ngokuqhelekileyo iqulethe iingcingo ezimbini ezihambelanayo ze-conductive core kunye ne-insulating material. Xa umsinga wombane udlula kwi-conductive core wire, ukushisa kwe-Joule kuveliswa, kubangela ukuba i-tape yokufudumala ishushu. Ubushushu bokufudumala kwetheyiphu yokufudumala bunokutshintshwa njengoko kufuneka.

Ukusetyenziswa kwetape yokufudumeza kwindlela engaphantsi kwendlela yokugquma umkhenkce:

1. I-antifreeze yombhobho

Kukho inani elikhulu lemibhobho kwindlela engaphantsi komhlaba, njengonikezelo lwamanzi kunye nemibhobho yokuhambisa amanzi, imibhobho yokukhusela umlilo, imibhobho yokungenisa umoya, njl. kukhokelela ekugqabhukeni okanye ekuvalelekeni. Ukuthintela oku kungenzeki, i-tape yokufudumala inokugqunywa ebusweni bombhobho. Ubushushu obuveliswa yi-tape yokufudumala ingasetyenziselwa ukugcina ukushisa ngaphakathi kombhobho kunye nokukhusela umbhobho ekukhenkceni.

2. Isixhobo sokukhenkceza

Kukho izixhobo ezininzi kwindlela kaloliwe engaphantsi komhlaba, ezinje ngeempompo zamanzi, iimotor, iziguquli, njl. Ezi zixhobo zikwachaphazeleka kukukhenkceza kwiindawo ezinobushushu obuphantsi ebusika, nto leyo ekhokelela kukusilela kwesixhobo. Ukuthintela oku kungenzeki, i-tape yokufudumeza inokugqunywa ebusweni besixhobo. Ubushushu obuveliswa yi-tape yokufudumala ingasetyenziselwa ukugcina ubushushu ngaphakathi kwesixhobo kunye nokukhusela izixhobo zokukhenkcela.

3. Ukugqunywa kwesitishi

Izikhululo zikaloliwe ezingaphantsi komhlaba ziyindawo ebalulekileyo yokuba abakhweli bangene kwaye baphume kuhola wendlela, kwaye kufuneka bagcine indawo efudumeleyo netofotofo. Ukuze ufezekise le njongo, ii-tapes zokufudumeza zingafakwa kwiindonga, iisilingi, imigangatho, njl njl. Ubushushu obuveliswa ngamateyipu okufudumeza bunokusetyenziswa ukunyusa izinga lokushisa ngaphakathi kwesitishi kunye nokuthintela ubushushu ngaphakathi kwesitishi ukuba bube buphantsi kakhulu.

Izinto eziluncedo zokufudumeza tape kwindlela yangaphantsi ye-antifreeze insulation:

1. Ukusebenza okuphezulu kunye nokonga amandla

Iteyiphu yokufudumeza yinto esebenza kakhulu yokugquma evelisa ubushushu ngokukhawuleza kwaye inokulungiswa njengoko kufuneka. Xa kuthelekiswa nezixhobo zendabuko zokugquma, iteyiphu yokufudumeza inomlinganiselo ophezulu wokusebenza kwamandla kwaye inokugcina ngokufanelekileyo amandla.

2. Ikhuselekile kwaye ithembekile

I-tape yokufudumeza yenziwe ngezinto ezikhuselayo kwaye ine-insulation efanelekileyo kunye neempawu zokungena kwamanzi. Ngethuba lokusetyenziswa, i-tape yokufudumeza ayiyi kubangela ingozi yokukhusela efana nomlilo ovulekileyo okanye ukuvuza, kwaye inokuqinisekisa ukusebenza okukhuselekileyo kwendlela ehamba phantsi.

3. Ukuyifaka ngokulula

Ufakelo lwetape yokufudumeza lukulungele kakhulu. Udinga kuphela ukugubungela i-tape yokufudumala ebusweni bombhobho okanye izixhobo ezifuna ukugqunywa. Ubude betape yokufudumeza bunokunqunyulwa njengoko kuyimfuneko ukulungiselela imibhobho kunye nezixhobo zeemilo ezahlukeneyo kunye nobukhulu.

4. Ulungiso olulula

Ukugcinwa kwetape yokufudumeza kulula kakhulu. Udinga kuphela ukujonga rhoqo ukusebenza kwe-insulation kunye nokufudumala kwe-tape yokufudumala. Ukuba i-tape yokufudumala ifunyenwe iphosakele okanye yonakaliswe, kuphela inxalenye eyonakalisiweyo idinga ukutshintshwa, kungekhona yonke i-tape yokufudumala.

Njengesixhobo esisebenzayo sokufakelwa kwe-thermal, iteyiphu yokufudumeza isetyenziswe ngokubanzi kwi-antifreeze insulation of subways. Inokuthintela ngempumelelo imibhobho, izixhobo kunye nezibonelelo ekubeni zingachatshazelwa ngumkhenkce kwiindawo ezinobushushu obuphantsi ebusika, ukuqinisekisa ukusebenza okuqhelekileyo kwendlela kaloliwe engaphantsi komhlaba. Ngelo xesha, i-tape yokufudumeza ineenzuzo zokusebenza okuphezulu, ukugcinwa kwamandla, ukhuseleko kunye nokuthembeka, ukufakwa lula kunye nokugcinwa okulula, okwenza kube yinto efanelekileyo yokukhetha ukutshatyalaliswa kwe-anti-freeze kwi-subways.
