Kutembenuka kwa Psi kupita ku MPa, psi ndi unit yokakamiza, yomwe imatanthauzidwa ngati mapaundi pa inchi imodzi, 145psi = 1MPa, PSI imatchedwa Pound sper square inch mu Chingerezi.P ndi mapaundi, S ndi masikweya, ndipo ine ndi inchi.Kutembenuza mayunitsi onse kukhala mayunitsi a metric kumabweretsa zokolola:
1bar≈14.5psi;1psi=6.895kPa=0.06895bar
Mayiko monga Europe ndi United States azolowera kugwiritsa ntchito psi ngati gawo
Ku China, timakonda kufotokoza kupanikizika kwa gasi mu "kg" (osati "jin"), ndipo gawo la thupi ndi "kg/cm^2".Kuthamanga kwa kilogalamu kumatanthauza kuti kilogalamu imodzi ya mphamvu imagwira ntchito pa centimita imodzi.
Chigawo chomwe chimagwiritsidwa ntchito kwambiri kunja ndi "Psi", ndipo gawo lenileni ndi "lb/in2", lomwe ndi "pounds per square inch".Chigawochi chikufanana ndi kutentha kwa Fahrenheit (F).
Komanso, pali Pa (Pascal, Newton amachita pa mita lalikulu), KPa, Mpa, Bar, millimeter madzi ndime, millimeter mercury ndime ndi mayunitsi kuthamanga.
1 bala (bar) = 0.1 MPa (MPa) = 100 kilopascal (KPa) = 1.0197 kg/cm²
1 standard atmospheric pressure (ATM) = 0.101325 MPa (MPa) = 1.0333 bar (bar)
Chifukwa kusiyana kwa mayunitsi ndikochepa kwambiri, mutha kulemba motere:
1 bar (bar) = 1 standard atmospheric pressure (ATM) = 1 kg/cm2 = 100 kilopascals (KPa) = 0.1 megapascals (MPa)
Kutembenuka kwa psi kuli motere:
Kuthamanga kwa 1 mumlengalenga (atm) = 14.696 mapaundi pa inchi 2 (psi)
Ubale wotembenuka mtima:
Pressure 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 of mercury (mmHg) = 133.322 Pa (Pa)
Mzere wa madzi 1 mm (mmH2O) = 9.80665 Pa (Pa)
1 engineering atmospheric pressure = 98.0665 kilopascals (kPa)
1 kilopascal (kPa) = 0.145 lbf/in2 (psi) = 0.0102 kgf/cm2 (kgf/cm2) = 0.0098 atmospheric pressure (atm)
1 pound force/inch 2 (psi) = 6.895 kilopascal (kPa) = 0.0703 kilogram mphamvu / centimeter 2 (kg/cm2) = 0.0689 bar (bar) = 0.068 atmospheric pressure (atm)
1 mphamvu ya mumlengalenga (atm) = 101.325 kilopascals (kPa) = 14.696 mapaundi pa inchi 2 (psi) = 1.0333 bar (bar)
Pali mitundu iwiri ya machitidwe a valve: imodzi ndi "yothamanga mwadzina" yomwe imayimiridwa ndi Germany (kuphatikizapo dziko langa) pogwiritsa ntchito mphamvu yovomerezeka yogwira ntchito kutentha (madigiri 100 m'dziko langa ndi madigiri 120 ku Germany).Chimodzi ndi "kutentha ndi kupanikizika" koyimiridwa ndi United States ndikuyimiridwa ndi kukakamizidwa kovomerezeka kogwira ntchito pa kutentha kwina.
Mu kutentha ndi kupanikizika dongosolo la United States, kupatula 150LB, amene zachokera madigiri 260, misinkhu zina zonse zochokera 454 madigiri.
Kupanikizika kovomerezeka kwa kalasi ya 150-psi (150psi = 1MPa) No. 25 carbon steel valve ndi 1MPa pa madigiri 260, ndipo kupanikizika kovomerezeka pa kutentha kumakhala kwakukulu kwambiri kuposa 1MPa, pafupifupi 2.0MPa.
Chifukwa chake, nthawi zambiri, mulingo wocheperako womwe umagwirizana ndi muyezo waku America 150LB ndi 2.0MPa, mulingo wapawiri womwe umafanana ndi 300LB ndi 5.0MPa, ndi zina zotero.
Chifukwa chake, kuthamanga mwadzina ndi kutentha ndi kupanikizika sikungasinthidwe mwachisawawa molingana ndi njira yosinthira.
Psi kupita ku MPa kutembenuza tebulo
Kusintha kwa PSI-MPa
