Cov qauv thiab cov qauv
Qhov sib txawv tshaj plaws nyob rau hauv lawv cov duab: tooj liab round raj muaj ib puag ncig cross-section, thaum tooj liab square tubes muaj ib tug square lossis rectangular cross-section. Qhov sib txawv ntawm cov qauv no ua rau muaj tus cwj pwm sib txawv ntawm kev quab yuam thiab kub diffusion.
Vim lawv cov qauv zoo sib xws, tooj liab puag ncig cov raj muaj peev xwm cuam tshuam qhov sib npaug sib npaug thaum raug rau sab hauv siab, tso cai rau lawv kom muaj kev ruaj ntseg zoo dua thaum thauj cov kua lossis cov xov xwm gaseous. Nyob rau hauv sib piv, tooj liab square tubes tej zaum yuav muaj kev ntxhov siab nyob rau hauv tej lub ces kaum, tab sis lawv cov square qauv ua rau lawv yooj yim dua rau kev sib txuas thiab kho, tshwj xeeb tshaj yog qhov haum haum ntawm lub raj tooj liab thiab lwm yam khoom.
Cov txheej txheem tsim khoom thiab nqi
Los ntawm kev tsim khoom, cov txheej txheem ntau lawm rau tooj liab puag ncig thiab tooj liab square tubing txawv. Round hlab feem ntau yog yooj yim dua thiab ntau npaum li cas los tsim vim hais tias lub round cross-section yog ib qho yooj yim los tswj thaum lub sij hawm ncab thiab dabtsi yog khoov txheej txheem, uas ua rau tooj liab alloy round raj ntau yig los tsim. Nyob rau hauv sib piv, kev tsim ntawm tooj liab square tubes yuav tsum tau ntau complex tooling thiab machining cov tswv yim, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm kev tuav tswj qhov tseeb ntawm cov ces kaum thiab qhov ncaj ntawm npoo, thiab yog li ntawd tus nqi kuj.
