I-Psi ukuya kwi-MPa ukuguqulwa, i-psi yiyunithi yoxinzelelo, echazwa njengeepounds nge-intshi yesikwere, 145psi = 1MPa, i-PSI ibizwa ngokuba yi-Pound sper square inch ngesiNgesi.P yiponti, S is square, kwaye mna yi-intshi.Ukuguqula zonke iiyunithi zibe ziiyunithi zemetriki isivuno:
I-1bar≈14.5psi;1psi=6.895kPa=0.06895bar
Amazwe afana neYurophu kunye neUnited States aqhele ukusebenzisa i-psi njengeyunithi
E-China, ngokuqhelekileyo sichaza uxinzelelo lwegesi kwi "kg" (kunokuba "jin"), kunye neyunithi yomzimba "kg / cm ^ 2".Ikhilogram enye yoxinzelelo ithetha ukuba ikhilogram enye yamandla isebenza kwi-square centimeter.
Iyunithi esetyenziswa ngokuxhaphakileyo phesheya yi “Psi”, kwaye iyunithi ethile yi “lb/in2″, eyi “pound per square intshi”.Le yunithi ifana neFahrenheit isikali sobushushu (F).
Ukongeza, kukho i-Pa (Pascal, enye iNewton isebenza kwimitha yesikwere), i-KPa, i-Mpa, iBar, ikholomu yamanzi e-millimeter, ikholamu ye-millimeter mercury kunye nezinye iiyunithi zoxinzelelo.
Ibha e-1 (ibha) = 0.1 MPa (MPa) = 100 kilopascal (KPa) = 1.0197 kg/cm²
I-1 umgangatho woxinzelelo lwe-atmospheric (ATM) = 0.101325 MPa (MPa) = 1.0333 ibha (bar)
Kuba umahluko kwiiyunithi umncinci kakhulu, ungawubhala ngolu hlobo:
Ibha ye-1 (ibha) = 1 uxinzelelo oluqhelekileyo lwe-atmospheric (ATM) = 1 kg / cm2 = 100 kilopascals (KPa) = 0.1 megapascals (MPa)
Ukuguqulwa kwe-psi ngolu hlobo lulandelayo:
I-1 umgangatho woxinzelelo lwe-atmospheric (atm) = 14.696 iipounds nge-intshi ye-2 (psi)
Ubudlelwane botshintsho loxinzelelo:
Uxinzelelo lwe-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 ye-mercury (mmHg) = 133.322 Pa (Pa)
Ikholamu yamanzi eyi-1 mm (mmH2O) = 9.80665 Pa (Pa)
I-1 yobunjineli yoxinzelelo lwe-atmospheric = 98.0665 kilopascals (kPa)
1 kilopascal (kPa) = 0.145 lbf/in2 (psi) = 0.0102 kgf/cm2 (kgf/cm2) = 0.0098 uxinzelelo lwe-atmospheric (atm)
I-1 pound force/intshi 2 (psi) = 6.895 kilopascal (kPa) = 0.0703 kilogram force / centimeter 2 (kg/cm2) = 0.0689 bar (bar) = 0.068 uxinzelelo lwe-atmospheric (atm)
I-1 yoxinzelelo lwe-atmospheric ngokomzimba (atm) = 101.325 kilopascals (kPa) = 14.696 iipounds nge-intshi nganye 2 (psi) = 1.0333 ibha (bar)
Kukho iintlobo ezimbini zeenkqubo zevalve: enye yinkqubo "yoxinzelelo lwegama" emelwe yiJamani (kubandakanywa nelizwe lam) ngokusekelwe kuxinzelelo oluvumelekileyo lokusebenza kwindawo yokushisa (i-100 degrees kwilizwe lam kunye ne-120 degrees eJamani).Enye "yinkqubo yobushushu kunye noxinzelelo" emelwe yi-United States kwaye imelwe yingcinezelo yokusebenza evumelekileyo kwiqondo lokushisa elithile.
Kwinkqubo yobushushu kunye noxinzelelo lwe-United States, ngaphandle kwe-150LB, esekelwe kwii-260 degrees, onke amanye amanqanaba asekelwe kwi-454 degrees.
Uxinzelelo oluvumelekileyo lweklasi ye-150-psi (150psi = 1MPa) Inombolo ye-25 carbon steel valve yi-1MPa kwii-degrees ezingama-260, kwaye uxinzelelo oluvumelekileyo kwiqondo lokushisa likhulu kakhulu kune-1MPa, malunga ne-2.0MPa.
Ngoko ke, ukuthetha ngokuqhelekileyo, inqanaba loxinzelelo lwegama elihambelana nomgangatho waseMelika we-150LB yi-2.0MPa, inqanaba loxinzelelo lwegama elihambelana ne-300LB yi-5.0MPa, njalo njalo.
Ngoko ke, uxinzelelo oluqhelekileyo kunye nokushisa kunye namabakala oxinzelelo alukwazi ukuguqulwa ngokungaqhelekanga ngokwefomula yokuguqula uxinzelelo.
I-Psi ukuya kwitafile yokuguqula uxinzelelo lwe-MPa
PSI-MPa ukuguqulwa
