Cov lus teb yog cev cev muaj qhov ua haujlwm siab dua rau ob qho tib si flex thiab torsional twisting dua xwmfab rau qhov hnyav muab. Siv ERW tub raws li nws yog ntau, ntau muaj zog dua tshaj CHS.
Tsis tas li kom paub yog, qhov twg yog qhov muaj zog channel lossis cov tub raj square?
Tube yog muaj zog dua . Lub cev plaub fab yog muaj zog dua tshaj puag ncig cev hauv khoov; puag ncig cev yog muaj zog dua hauv torsion (twisting). Ob leeg yog muaj zog dua tshaj channel.
Tom qab ntawd, lo lus nug yog, lub voj voog puas muaj zog dua li square? Hauv kev tsim vaj tsev, yog tias ib kab lus tau hloov pauv zoo ib yam li a xwmfab ntawm tib cheeb tsam, ces tus lub voj voog yog muaj zog dua . Txawm li cas los xij, yog tias muaj kab teeb hla hla ob phab ntsa thiab ntu yog ncig ces nws tsis muaj zog tshaj li ib lub xwmfab ntu Ntawm no xwmfab /rectangular yog muaj zog dua los ntawm kev txiav txim siab stability.
Dhau li, kuv puas muaj zog dua li cov tub raj?
Ib I- nqaj tau tsim los muab qhov zoo tshaj plaws kuv los ntawm kev muaj qhov sib faib loj dua ntawm thaj tsam ntu ntu sib nrug deb ntawm qhov chaw nruab nrab ntawm nqaj . Plaub fab cev nrog qhov ntev tshaj plaws ntsug ntsug yog tom ntej thiab xwmfab yog qhov phem tshaj vim qhov kuv rau ntu ntu nyob ntawm lub zog thib peb ntawm txoj kab ntsug.
Muaj zog npaum li cas square steel tubing?
Feem ntau (thiab tej zaum pheej yig tshaj) xwmfab yam ntxwv tub yog tsim los ntawm A36 carbon hlau nrog qhov siab tshaj tawm los ntawm 36, 000 psi. Tej zaum yuav muaj cov qhab nia zoo dua, tab sis koj yuav tsum tau txheeb xyuas nrog (lossis google) hlau cov neeg muab khoom. Max shear kev nyuaj siab yuav tsum tau khaws cia hauv qab 14, 400 psi.

ICS thaj chaw ua haujlwm twg teeb tsa cov phiaj xwm phiaj xwm phiaj xwm thiab ua ntej thiab muaj lub luag haujlwm tag nrho rau qhov xwm txheej?
Cov lus txib xwm txheej yog lub luag haujlwm rau kev teeb tsa lub hom phiaj xwm txheej, cov tswv yim thiab qhov tseem ceeb. Nws kuj muaj lub luag haujlwm tag nrho rau qhov xwm txheej
Dab tsi yog qhov qaug zog acid thiab muaj zog puag tsim?
Cov ntsev ntawm cov kua qaub tsis muaj zog thiab lub hauv paus muaj zog ua rau hydrolysis hauv dej los tsim OH-ions ntxiv. Txij li thaum acetic acid yog ib qho tsis muaj zog acid, nws tseem unionized nyob rau hauv kev daws thiab cov OH-ions ua rau cov tshuaj yooj yim los yog alkaline. Ib yam li ntawd, ntsev ntawm lub zog acid thiab tsis muaj zog hauv paus yog acidic nyob rau hauv aqueous tov
Dab tsi yog qhov cuam tshuam ib puag ncig ntawm hnub ci zog?
Lub peev xwm ntawm ib puag ncig cuam tshuam nrog lub hnub ci zog-kev siv av thiab chaw nyob, kev siv dej, thiab kev siv cov khoom phom sij hauv kev tsim khoom- tuaj yeem sib txawv heev nyob ntawm cov thev naus laus zis, uas suav nrog ob pawg dav: photovoltaic (PV) hnub ci hlwb lossis tsom rau hnub ci. Thermal nroj tsuag (CSP)
Vim li cas cov duab ntawm titration nkhaus txawv rau titration ntawm muaj zog acid vs muaj zog puag thiab qaug zog acid vs muaj zog puag?
Cov duab dav dav ntawm titration nkhaus yog tib yam, tab sis pH ntawm qhov sib npaug sib txawv. Hauv qhov tsis muaj zog acid-muaj zog titration, pH yog ntau dua 7 ntawm qhov sib npaug. Hauv qhov muaj zog acid-tsis muaj zog titration, pH tsawg dua 7 ntawm qhov sib npaug
Dab tsi yog txhais los ntawm Ib puag ncig Vim li cas ib puag ncig suav tias yog qhov system?
Ib puag ncig yog suav tias yog qhov system vim peb tsis tuaj yeem nyob tsis muaj ib puag ncig yog tias tsis muaj tsob ntoo yuav tsis muaj oxygen thiab tsis muaj sia
