Phetolelo ea Psi ho MPa, psi ke yuniti ea khatello, e hlalosoang e le liponto ka sekwere-inch, 145psi = 1MPa, PSI e bitsoa Pound sper square inch ka Senyesemane.P ke ponto, S ke lisekoere, 'me 'na ke inch.Ho fetolela likarolo tsohle ho metric unit ho hlahisa litholoana:
1bar≈14.5psi;1psi=6.895kPa=0.06895bar
Linaha tse kang Europe le United States li tloaetse ho sebelisa psi e le sehlopha
Chaena, ka kakaretso re hlalosa khatello ea khase ka "kg" (ho e-na le "jin"), 'me karolo ea' mele ke "kg/cm^2".K'hilograma e le 'ngoe ea khatello e bolela hore kilogram e le' ngoe ea matla e sebetsa ka lisenthimithara tse le 'ngoe.
Yuniti e sebelisoang hangata kantle ho naha ke "Psi", mme yuniti e ikhethileng ke "lb/in2", e leng "pound per square inch".Yuniti ena e tšoana le sekala sa mocheso oa Fahrenheit (F).
Ho phaella moo, ho na le Pa (Pascal, Newton e le 'ngoe e sebetsa ka mithara e le' ngoe ea lisekoere), KPa, Mpa, Bar, kholomo ea metsi ea millimeter, kholomo ea millimeter mercury le likarolo tse ling tsa khatello.
1 bar (bar) = 0.1 MPa (MPa) = 100 kilopascal (KPa) = 1.0197 kg/cm²
1 khatello e tloaelehileng ea sepakapaka (ATM) = 0.101325 MPa (MPa) = 1.0333 bar (bar)
Hobane phapang ea likarolo e nyane haholo, o ka e ngola tjena:
1 bar (bar) = 1 khatello e tloaelehileng ea sepakapaka (ATM) = 1 kg/cm2 = 100 kilopascals (KPa) = 0.1 megapascals (MPa)
Phetoho ea PSI e shebahala tjena:
1 khatello e tloaelehileng ea sepakapaka (atm) = 14.696 liponto ka inch 2 (psi)
Kamano ea phetoho ea khatello:
Khatello 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 ea mercury (mmHg) = 133.322 Pa (Pa)
1 mm kholomo ea metsi (mmH2O) = 9.80665 Pa (Pa)
Khatello ea sepakapaka e 1 = 98.0665 kilopascals (kPa)
1 kilopascal (kPa) = 0.145 lbf/in2 (psi) = 0.0102 kgf/cm2 (kgf/cm2) = 0.0098 khatello ea sepakapaka (atm)
1 pound force/inch 2 (psi) = 6.895 kilopascal (kPa) = 0.0703 kilogram force / centimeter 2 (kg/cm2) = 0.0689 bar (bar) = 0.068 khatello ea sepakapaka (atm)
Khatello e 1 ea sepakapaka (atm) = 101.325 kilopascals (kPa) = 14.696 pounds ka inch 2 (psi) = 1.0333 bar (bar)
Ho na le mefuta e 'meli ea litsamaiso tsa li-valve: e' ngoe ke "khatello ea lebitso" e emetsoeng ke Jeremane (ho kenyeletsoa naha ea heso) ho latela khatello e lumelletsoeng ea ho sebetsa mocheso oa kamore (100 degrees naheng ea heso le 120 degrees Jeremane).E 'ngoe ke "sistimi ea mocheso le khatello" e emeloang ke United States mme e emetsoe ke khatello e lumelletsoeng ea ho sebetsa mochesong o itseng.
Tsamaisong ea mocheso le khatello ea United States, ntle le 150LB, e thehiloeng ho likhato tse 260, maemo a mang kaofela a thehiloe ho likhato tse 454.
Khatello e amohelehang ea sehlopha sa 150-psi (150psi = 1MPa) No. 25 carbon steel valve ke 1MPa ka likhato tsa 260, 'me khatello e lumelletsoeng ka mocheso oa kamore e kholo haholo ho feta 1MPa, e ka bang 2.0MPa.
Ka hona, ha re bua ka kakaretso, boemo ba khatello ea lebitso bo tsamaellanang le maemo a Amerika a 150LB ke 2.0MPa, boemo ba khatello ea lebitso bo tsamaellanang le 300LB ke 5.0MPa, joalo-joalo.
Ka hona, khatello ea lebitso le mocheso le likhatello tsa khatello li ke ke tsa fetoloa ka mokhoa o sa tloaelehang ho latela mokhoa oa ho fetola khatello.
