Psi rau MPa hloov dua siab tshiab, psi yog ib chav tsev siab, txhais tau tias yog phaus ib square inch, 145psi = 1MPa, PSI hu ua Pound sper square inch hauv lus Askiv.P yog phaus, S yog square, thiab kuv yog nti.Hloov tag nrho cov units rau metric units yields:
1bar≈14.5psi;1 psi = 6.895kPa = 0.06895bar
Cov teb chaws xws li Europe thiab Tebchaws Meskas tau siv los siv psi ua ib chav
Hauv Suav teb, peb feem ntau piav qhia qhov siab ntawm cov pa hauv "kg" (tsis yog "jin"), thiab lub cev yog "kg / cm^2".Ib kilogram siab txhais tau hais tias ib kilogram ntawm quab yuam ua rau ib square centimeter.
Chav tsev feem ntau siv txawv teb chaws yog "Psi", thiab chav tsev tshwj xeeb yog "lb / hauv 2", uas yog "phaus ib square inch".Chav tsev no zoo li qhov ntsuas kub Fahrenheit (F).
Tsis tas li ntawd, muaj Pa (Pascal, ib qho Newton ua rau ib square meter), KPa, Mpa, Bar, millimeter dej kem, millimeter mercury kem thiab lwm yam siab units.
1 bar (bar) = 0.1 MPa (MPa) = 100 kilopascal (KPa) = 1.0197 kg/cm²
1 tus qauv atmospheric siab (ATM) = 0.101325 MPa (MPa) = 1.0333 bar (bar)
Vim tias qhov sib txawv ntawm cov chav nyob me me, koj tuaj yeem sau nws li no:
1 bar (bar) = 1 tus qauv atmospheric siab (ATM) = 1 kg / cm2 = 100 kilopascals (KPa) = 0.1 megapascals (MPa)
Kev hloov pauv psi yog raws li hauv qab no:
1 tus qauv atmospheric siab (atm) = 14.696 phaus ib nti 2 (psi)
Kev sib raug zoo ntawm kev sib hloov siab:
Siab 1 bar (bar) = 10^5 Pa (Pa) 1 dyne/cm2 (dyn/cm2) = 0.1 Pa (Pa)
1 Torr (Torr) = 133.322 Pa (Pa) 1 millimeter mercury (mmHg) = 133.322 Pa (Pa)
1 hli dej kem (mmH2O) = 9.80665 Pa (Pa)
1 engineering atmospheric siab = 98.0665 kilopascals (kPa)
1 kilopascal (kPa) = 0.145 lbf/in2 (psi) = 0.0102 kgf/cm2 (kgf/cm2) = 0.0098 atmospheric siab (atm)
1 phaus force/inch 2 (psi) = 6.895 kilopascal (kPa) = 0.0703 kilogram force / cm2 (kg/cm2) = 0.0689 bar (bar) = 0.068 atmospheric pressure (atm)
1 lub cev atmospheric siab (atm) = 101.325 kilopascals (kPa) = 14.696 phaus ib nti 2 (psi) = 1.0333 bar (bar)
Muaj ob hom valve systems: ib qho yog "nominal siab" system sawv cev los ntawm lub teb chaws Yelemees (nrog rau kuv lub teb chaws) raws li kev tso cai ua hauj lwm siab ntawm chav tsev kub (100 degrees hauv kuv lub teb chaws thiab 120 degrees hauv lub teb chaws Yelemees).Ib qho yog "qhov kub thiab txias" uas sawv cev los ntawm Tebchaws Meskas thiab sawv cev los ntawm kev tso cai ua haujlwm siab ntawm qhov kub thiab txias
Nyob rau hauv qhov kub thiab txias system ntawm Teb Chaws Asmeskas, tshwj tsis yog rau 150LB, uas yog raws li 260 degrees, tag nrho lwm theem yog raws li 454 degrees.
Qhov kev ntxhov siab tso cai ntawm 150-psi chav kawm (150psi = 1MPa) No. 25 carbon steel valve yog 1MPa ntawm 260 degrees, thiab qhov kev ntxhov siab tso cai ntawm chav tsev kub yog ntau dua 1MPa, txog 2.0MPa.
Yog li ntawd, feem ntau hais lus, lub nominal siab theem sib xws rau American standard 150LB yog 2.0MPa, lub nominal siab theem sib xws rau 300LB yog 5.0MPa, thiab hais txog.
Yog li ntawd, lub nominal siab thiab kub thiab siab qib tsis tuaj yeem hloov pauv raws li cov qauv hloov pauv siab.
