Cov kav hlau tsis muaj qhov thiab cov kav hlau welded ua lub luag haujlwm tseem ceeb ua cov khoom tseem ceeb ntawm kev lag luam niaj hnub no.
Cov lus qhia ntawm cov raj no feem ntau yog txhais los ntawm lub cheeb sab nraud (OD), phab ntsa tuab (WT) thiab ntev (L), thaum xam qhov hnyav ntawm cov raj hlau yog raws li cov kev ntsuas no ntxiv rau qhov ceev (ρ) ntawm cov khoom. Rau kev npaj phiaj xwm, kev tswj tus nqi thiab kev xa khoom, kev xam qhov hnyav ntawm cov yeeb nkab hlau yog qhov tseem ceeb. Tsab xov xwm no nthuav qhia peb txoj hauv kev rau kev xam qhov hnyav ntawm cov yeeb nkab hlau thiab qhia yuav siv lawv li cas nrog cov piv txwv ua tau.
Kev Xam Xam Yooj Yim ntawm Qhov Hnyav Yeeb Nkab
Qhov hnyav ntawm cov yeeb nkab hlau tuaj yeem kwv yees los ntawm kev xam nws qhov ntim muab faib rau qhov ceev ntawm cov hlau.
Rau cov kav hlau puag ncig (xws li cov seamless thiabcov kav hlau vuam), qhov hnyav yog xam raws li nram no:
Qhov hnyav(kg)=×(OD)2-(OD-2 × WT)2)×L×ρ
ODyog lub cheeb sab nraud ntawm cov yeeb nkab hlau hauv meters (m);
WTyog phab ntsa tuab ntawm cov yeeb nkab hlau hauv meters (m);
Lyog qhov ntev ntawm cov yeeb nkab hlau hauv meters (m);
ρyog qhov ceev ntawm cov hlau, rau cov hlau carbon ib txwm, nws yog li 7850kg / m3.
Cov txheej txheem yooj yim: cov chav imperial
Qhov hnyav(lb/ft)=(OD (hauv)−WT (hauv)) ×WT (hauv) × 10.69
qhov twg 10.69 yog ib qho piv txwv suav los ntawm qhov ceev ntawm cov hlau thiab kev hloov pauv chav tsev siv los hloov qhov ntev ntawm nti mus rau phaus ib ko taw ntawm qhov ntev.
Piv txwv kev suav
Xav tias ib feem ntawmERW yeeb nkab hlaunrog rau sab nraud txoj kab uas hla ntawm 10 nti thiab phab ntsa tuab ntawm 0.5 nti, xam qhov hnyav ib ko taw ntawm qhov ntev: Qhov hnyav (lb/ft) = (10-0.5) x 0.5 x 10.69
Qhov hnyav ib ko taw ntawm qhov ntev ntawm cov yeeb nkab hlau no yog kwv yees li 50.7775 phaus.
Cov txheej txheem yooj yim: cov chav ntsuas
Qhov hnyav (kg) = (OD − WT) × WT × L × 0.0246615
OD yog lub cheeb sab nraud ntawm cov yeeb nkab hlau, hauv meters (mm);
WT yog phab ntsa tuab ntawm cov yeeb nkab hlau hauv meters (mm);
L yog qhov ntev ntawm lub raj hauv meters (m);
0.0246615 yog raws li qhov ceev ntawm hlau (kwv yees li 7850 kg / m³) thiab qhov hloov pauv ntawm chav tsev.
Piv txwv kev suav
Xav tias peb muaj ibcov yeeb nkab hlau tsis muaj seamlessnrog rau sab nraud txoj kab uas hla ntawm 114.3 hli, phab ntsa tuab ntawm 6.35 hli, thiab ntev ntawm 12 m. Xam qhov hnyav ntawm cov yeeb nkab siv cov mis yooj yim saum toj no:
1. Xam qhov sib txawv ntawm txoj kab uas hla thiab phab ntsa tuab: 114.3 - 6.35 = 107.95. 2.
2. Xam qhov hnyav los ntawm kev hloov cov mis: 107.95 × 6.35 × 12 × 0.0246615. 3.
3. Qhov tshwm sim yog: 202.86
Yog li ntawd, tag nrho qhov hnyav ntawm cov yeeb nkab yog kwv yees li 202.86 kg.
Cov coefficients 10.69 thiab 0.0246615 hauv cov mis no yog raws li qhov nruab nrab ntawm cov hlau. Cov hlau sib txawv (piv txwv li hlau tsis xeb, hlau sib xyaw, thiab lwm yam) yuav muaj qhov sib txawv ntawm cov ntom ntom thiab cov yam ntxwv yuav tsum tau kho raws li qhov ntawd.
Cov kev xam no muab kev kwv yees ntawm qhov hnyav ntawmtsis muaj qhov tsis sib xwsthiab cov kav hlau vuam. Vim muaj ntau yam khoom siv sib txawv, kev kam rau siab ntawm kev tsim khoom, thiab lwm yam, qhov hnyav tiag tiag yuav txawv.
Qhov hnyav tiag tiag yuav txawv nyob ntawm seb qhov kev kam rau siab ntawm kev tsim khoom thiab qhov ceev ntawm cov khoom siv, yog li cov qauv no tsuas yog kwv yees xwb. Yog xav kom paub tseeb tias qhov hnyav yog li cas, nws raug nquahu kom koj siv cov ntaub ntawv uas tus neeg tsim khoom muab los yog ntsuas qhov tseeb.
Yog xav tau kev xam lej engineering kom raug lossis kev hais nqe lag luam, nws raug pom zoo kom siv cov ntaub ntawv kom ntxaws ntxiv lossis hu rau cov neeg muab khoom yeeb nkab kom tau cov ntaub ntawv qhov hnyav raug.
Kev xam qhov hnyav ntawm cov yeeb nkab yog ib feem tseem ceeb ntawm kev tsim qauv engineering thiab kev tswj tus nqi, thiab kev nkag siab zoo thiab kev siv cov kev xam no Txoj kev xam no siv tau rau cov yeeb nkab hlau tsis muaj qhov sib txuas nrog cov phab ntsa nyias nyias. Hauv cov yeeb nkab hlau tsis muaj qhov sib txuas nrog phab ntsa tuab heev, tej zaum yuav xav txog kev xam ntau dua.
cov cim npe: qhov hnyav ntawm cov yeeb nkab, cov yeeb nkab hlau, seamless, welded.
