Hydrostatic Kev Ntsuam Xyuas
Txhua qhov ntev ntawm cov yeeb nkab yuav tsum raug sim los ntawm cov khw mus rau lub tshuab cua hydostatic Lub siab yuav tsum txiav txim siab los ntawm kab sib luag hauv qab no:
P = 2st / d
Kev tso cai sib txawv hauv qhov hnyav thiab qhov ntev
Txhua qhov ntev ntawm cov yeeb nkab yuav tsum tau sib cais thiab nws qhov hnyav yuav tsis sib txawv ntau dua 10% dhau los yog nws qhov hnyav, suav siv nws qhov ntev thiab qhov hnyav rau ib ntu ntev.
Cov taub sab nraud yuav tsis sib txawv ntau dua ± 1% los ntawm cov kev cai tshwj xeeb sab nraud ntawm lub taub.
Phab ntsa tuab ntawm txhua qhov taw tes yuav tsum tsis ntau tshaj 12.5% nyob rau hauv cov phab ntsa dicently.
Qho ntev
Ib Leeg Random ntev: 16 txog 25ft (4.88 txog 7.62m)
Ob chav random ntev: ntau dua 25ft rau 35ft (7.62 txog 10.67m)
Uniform ntev: kev tiv thaiv kev sib tw ± 1in
Xaus
Cov yeeb nkab nqa yuav tsum tau muab cov ntaub nyias nyias xaus, thiab cov burrs ntawm qhov kawg yuav raug tshem tawm
Thaum cov yeeb nkab kawg tau teev tseg rau Bevel xaus, lub kaum sab xis yuav yog 30 txog 35 degree
