Psi kuMPa shanduko, psi inzvimbo yekumanikidza, inotsanangurwa semapaundi pa square inch, 145psi = 1MPa, PSI inonzi Pound sper square inch kuChirungu.P ipound, S ikona, uye ini inchi.Kushandura mayuniti ese kuita metric mauniti kunobereka:
1bar≈14.5psi;1psi=6.895kPa=0.06895bar
Nyika dzakaita seEurope neUnited States dzakajaira kushandisa psi sechikamu
MuChina, isu tinowanzo tsanangura kudzvanywa kwegasi mu "kg" (panzvimbo pe "jin"), uye chikamu chemuviri "kg/cm^2".One kilogram of pressure zvinoreva kuti kirogiramu imwe yesimba inoshanda pane imwe square centimeter.
Iyo inowanzoshandiswa unit kunze kwenyika ndeye "Psi", uye iyo chaiyo unit ndeye "lb/in2", inova "pondo per square inch".Ichi chikamu chakafanana neFahrenheit tembiricha scale (F).
Mukuwedzera, pane Pa (Pascal, imwe Newton inobata pane imwe square mita), KPa, Mpa, Bar, millimeter yemvura column, millimeter mercury column uye mamwe maitiro ekumanikidza.
1 bha (bha) = 0.1 MPa (MPa) = 100 kilopascal (KPa) = 1.0197 kg/cm²
1 yakajairwa atmospheric pressure (ATM) = 0.101325 MPa (MPa) = 1.0333 bar (bha)
Nekuti musiyano mumayuniti idiki kwazvo, unogona kunyora seizvi:
1 bar (bar) = 1 chiyero chemhepo yemhepo (ATM) = 1 kg/cm2 = 100 kilopascals (KPa) = 0.1 megapascals (MPa)
Iko kutendeuka kwepsi kunotevera:
1 yakajairwa atmpheric pressure (atm) = 14.696 pounds per inch 2 (psi)
Pressure shanduko hukama:
Kudzvanya 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 yemekiyuri (mmHg) = 133.322 Pa (Pa)
1 mm mbiru yemvura (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 simba / centimita 2 (kg/cm2) = 0.0689 bar (bar) = 0.068 atmospheric pressure (atm)
1 physical atmpheric pressure (atm) = 101.325 kilopascals (kPa) = 14.696 pounds per inch 2 (psi) = 1.0333 bar (bar)
Kune mhando mbiri dzemavharuvhu masisitimu: imwe ndeye "nominal pressure" system inomiririrwa neGermany (kusanganisira nyika yangu) zvichibva pakumanikidzwa kushanda kunobvumirwa patembiricha yekamuri (100 madhigirii munyika yangu uye 120 madhigirii kuGermany).Imwe ndeye "tembiricha uye kumanikidza system" inomiririrwa neUnited States uye inomiririrwa neinobvumirwa kushanda kumanikidza pane imwe tembiricha.
Mune tembiricha uye kumanikidza system yeUnited States, kunze kwe150LB, iyo yakavakirwa pa260 madhigirii, mamwe ese mazinga akavakirwa pa454 madhigirii.
Kushungurudzika kunobvumirwa kwekirasi ye150-psi (150psi = 1MPa) No. 25 carbon steel valve is 1MPa pa 260 degrees, uye kushushikana kunobvumirwa pakushambidzika kwekamuri kwakakura kudarika 1MPa, inenge 2.0MPa.
Naizvozvo, kazhinji kutaura, iyo yezita yekumanikidza level inoenderana neAmerican standard 150LB ndeye 2.0MPa, iyo yezita yekumanikidza level inoenderana ne300LB ndeye 5.0MPa, zvichingodaro.
Naizvozvo, iyo yezita kudzvinyirirwa uye tembiricha uye kudzvanywa mamakisi hazvigone kushandurwa zvakajairika zvinoenderana neiyo yekumanikidza shanduko formula.
Psi kuenda kuMPa pressure yekushandura tafura
PSI-MPa kutendeuka
