Incazelo ye-PSI ne-PSI: Amayunithi Okucindezela, Umehluko, kanye Nokuguqulwa
Iyini i-PSI?
I-PSI (Amaphawundi nge-Inch yesikwele) ilinganisa ingcindezi ngokubala amandla (amaphawundi) asetshenziswa ku-intshi eyodwa yesikwele yendawo. Isetshenziswa kakhulu ezinhlelweni ze-hydraulic, ingcindezi yamathayi, kanye nemishini yezimboni, iyiyunithi ejwayelekile yengcindezi yasebukhosini.
Qaphela: I-PSI ingase futhi ibhekisele ezezimali (Umnikelo Wemali Wokuqala) noma umuthi (I-Postpartum Stress Inventory), kodwa lo mhlahlandlela ugxile ezimweni zobunjiniyela.
I-PSI njengeyunithi yokucindezela
Incazelo
I-PSI ilinganisa ingcindezi lapho amandla angu-1 lb esebenza endaweni eyi-1 in². Inamandla kakhulu e-US/UK kwezinhlelo zokusebenza zobunjiniyela.
Ukuguqulwa Okuyinhloko
| I-PSI | kPa | ibha | I-MPa |
|---|---|---|---|
| I-PSI engu-1 | 6.895 | 0.0689 | 0.00689 |
| 1 i-atm | 101.3 | 1.013 | 0.1013 |
| Okulinganayo | I-atm e-1 ≈ 14.696 PSI | I-MPa engu-1 ≈ 145 PSI |
Isibonelo Somhlaba Wangempela
-I-WOG eyi-1000I-Ball Valve: Kusho ivalvu yebhola ye-PSI eyi-1000 = ibha engu-68.95 noma i-6.895 MPa
-AI-2000 WOG Ball Valve: Kusho ivalvu yebhola ye-PSI engu-2000 = ibha engu-137.9 noma i-13.79 MPa
Iyini i-PSIG?
Incazelo ye-PSIG
I-PSIG (Amaphawundi nge-Square Inch Gauge) ilinganisa ingcindezi yokulinganisa—ingcindeziuma kuqhathaniswa nomfutho womoya. Liyinani eliboniswa kuma-gauge amaningi okucindezela.
I-PSI vs i-PSI: Umehluko Omkhulu
| Ithemu | Uhlobo | Indawo Yokubhekisela | Ifomula |
|---|---|---|---|
| I-PSI | Kuncike kumongo | Kuyahlukahluka (ngokuvamile = i-PSIG) | Iyunithi ejwayelekile |
| I-PSIG | Ingcindezi yegeyiji | Ingcindezi yomoya yendawo | I-PSIG = I-PSIA – 14.7 |
| I-PSIA | Ingcindezi ephelele | I-vacuum ephelele | I-PSIA = I-PSIG + 14.7 |
Izibonelo Eziwusizo
Ithayi elibhalwe ukuthi “35 PSI” = 35 PSIG (ingcindezi yokulinganisa).
I-vacuum ezingeni lolwandle ifundeka ngo--14.7 PSIG (PSIA = 0).
I-PSI vs i-PSIG: Izicelo Eziyinhloko
Amacala Okusetshenziswa Kwezimboni
I-PSIG:Kusetshenziswa kuma-gauge okucindezela, kuma-compressor, kanye nasezinhlelweni ze-hydraulic (isb., ukulinganisa umfutho wamathayi noma umfutho wamapayipi).
I-PSIA:Okubalulekile ezinhlelweni zezindiza/ze-vacuum lapho ukucindezela okuphelele kubaluleke khona.
Ukucaciswa Kobuchwepheshe
Amadokhumenti avame ukufinyeza i-PSI ngokuthi “i-PSI,”kodwa izimo eziqinile zidinga ukuhlukaniswa (isib., uhlu lwemininingwane yendiza oluthi “18 PSI” kodwa olusho ukuthi 18 PSIG).
Dwebela ushiye isithupha:Iningi lezibalo ze-"PSI" zezimboni empeleni yi-PSI.
Amathebula Okuguqulwa Okuphelele kwe-PSI
Ukuguqulwa Kweyunithi Yokucindezela
| Iyunithi | I-PSI | ibha | I-MPa |
|---|---|---|---|
| I-PSI engu-1 | 1 | 0.0689 | 0.00689 |
| Ibha eli-1 | 14.5 | 1 | 0.1 |
| I-MPa eyi-1 | 145 | 10 | 1 |
Okunye Ukuguqulwa Okuyinhloko
I-PSI eyi-1 = 0.0703 kg/cm²
1 kg/cm² = 14.21 PSI
1 i-atm = 14.696 PSI = 101.3 kPa = 760 mmHg
Imibuzo Evame Ukubuzwa: I-PSI ne-PSIG
U: Ingabe i-PSI iyafana ne-PSI?
A: Empeleni, igama elithi “PSI” livame ukusho i-PSI (ingcindezi yokulinganisa). Ngobuchwepheshe, i-PSI ayicaci kahle, kanti i-PSIngokucacileizinkomba zokucindezela komoya.
Q: Kungani ama-valve esebenzisa izilinganiso ze-PSI?
A: I-PSI ikhombisa ukubekezelela okuphezulu kwengcindezi (*isib., ivalvu ye-PSI engu-1000 = ibha engu-68.95*).
U: Kufanele ngisebenzise nini i-PSIA vs i-PSIG?
A: Sebenzisa i-PSIG ukuze uthole ukufundwa komfutho wemishini; i-PSIA ukuze uthole izinhlelo ze-vacuum noma izibalo zesayensi.
Izinto Ezibalulekile Okufanele Uzicabangele
1. I-PSI = amandla nge-intshi yesikwele; I-PSI = I-PSI uma kuqhathaniswa nomfutho womoya.
2. Amanani amaningi e-"PSI" ezimboni yi-PSIG (isb., umfutho wamathayi, izilinganiso zamavalvu).
3. Ukuguqulwa okubalulekile: 1 PSI = 0.0689 ibha, 1 MPa = 145 PSI.
