Boiler Boiler
Machubu a boiler ndi amodzi mwa mapaipi opanda msoko.Njira zopangira ndizofanana ndi chubu chopanda msoko, koma zimakhala ndi zofunikira zopanga mapaipi achitsulo.Kutengera kutentha, chubu cha boiler chimagawidwa m'machubu opopera wamba komanso chubu chopopera chambiri.
Njira zopangira:
① general boiler chubu kutentha ndi pansi 450 ℃, ntchito chitoliro otentha-anagulung'undisa kapena ozizira kukokedwa chubu kupanga zitsulo chitoliro.
② chubu chopopera chokwera kwambiri chimagwiritsidwa ntchito nthawi zambiri pakatentha kwambiri komanso chitoliro champhamvu, zotsatira za mpweya wotentha kwambiri komanso mpweya wamadzi, makutidwe ndi okosijeni ndi dzimbiri.Chitoliro chachitsulo chokhala ndi mphamvu yophulika kwambiri, kukana kwambiri kwa mpweya wa okosijeni ndikukhala ndi kukhazikika kwadongosolo.
Zolinga za machubu a boiler:
① machubu otenthetsera wamba amagwiritsidwa ntchito makamaka popanga machubu a khoma lamadzi, machubu m'madzi otentha ndi chitoliro cha nthunzi yotentha kwambiri, machubu otenthetsera kwambiri, machubu akulu ndi ang'onoang'ono a utsi ndi njerwa.
② chubu chotenthetsera kwambiri chimagwiritsidwa ntchito makamaka popanga machubu othamanga kwambiri komanso machubu otenthetsera kwambiri, machubu otenthetsera, mpweya, chitoliro chachikulu cha nthunzi.
Gulu:
Machubu a boiler ambiri komanso machubu opopera opopera kwambiri amawonetsedwa ndi kutentha kwambiri.Machubu a boiler ambiri, kapena machubu othamanga kwambiri malinga ndi momwe amagwiritsira ntchito amatha kugawidwa mumitundu yosiyanasiyana yazitsulo.
Miyezo ndi zinthu zachitsulo chitoliro likupezeka pa carbon, aloyi, ndi zosapanga dzimbiri zakuthupi.

Makulidwe Ofanana: OD kuchokera 6mm kuti 1240mm, makulidwe kuchokera 1mm kuti 50mm
Mitundu:Chitoliro chowongoka chowongoka, ndi chitoliro chachitsulo cha U boiler cha chubu exchanger mtolo.
Miyezo iyi imafotokoza za gulu, kukula, mawonekedwe, kulemera ndi kupatuka kovomerezeka, zofunikira zaukadaulo, kuyang'anira ndi kuyesa, kuyika, kuyika chizindikiro ndi satifiketi yaubwino wa machubu opanda zitsulo opanda waya.
