    Kambani yedu inonyanya kutengesa mapaipi akasiyana-siyana esimbiBoiler Mapaipi, Boiler simbi mapaipi, boiler simbi machubhu, boilers machubhu, China Boiler. Vazhinji vatengesi vekutengesa vanosangana nematambudziko kana vachitora, semuenzaniso musiyano pakati pesimbi chaiyo huremu uye theoretical huremu. Rega ndipindure mubvunzo uyu kune wese.

    1. Theoretical huremu hwesimbi

    The theoretical huremu hwesimbi hunowanikwa nekuverenga hukuru hwezita uye density (inodanwa kunzi huremu chaihwo munguva yakapfuura). Izvi zvinoenderana zvakananga nehurefu hwesimbi, nzvimbo yemuchinjiko, uye kutsauka kwehukuru hunobvumidzwa. Nekuda kwekutsauka kunobvumidzwa mukugadzira, iyo yakaverengerwa huremu huremu hwakasiyana neimwe kukosha, uye kukosha kweiyo theoretical ndeyekutarisa chete uchifungidzira.

    2. Kurema chaiko kwesimbi

    Huremu chaihwo hwesimbi zvinoreva huremu hunowanikwa nekuyera chaiko (nechikero). Huremu chaihwo hwakarurama kupfuura huremu hwedzidziso.

    Overview

    Application

    Inonyanya kushandiswa kugadzira yakakwirira-mhando kabhoni structural simbi, alloy structural simbi uye isina kupisa-inodzivirira simbi isina musono pombi dzesimbi yekumanikidza yakakwira uye pamusoro pemhepo boiler pombi.

    Inonyanya kushandiswa kune yakanyanya kudzvanywa uye yakanyanya tembiricha sevhisi ye boiler (Superheater chubhu, reheater chubhu, mhepo inotungamira chubhu, main steam chubhu yekumusoro uye yakanyanya kudzvanywa boilers). Pasi pechiito chepamusoro tembiricha flue gasi uye mhute yemvura, iyo chubhu ichave oxidize uye corrode. Zvinotarisirwa kuti pombi yesimbi ine kusimba kwepamusoro, kupikisa kwakanyanya kune oxidation uye corrosion, uye kunaka kwemaitiro kugadzikana.
