Tsananguro yePSI nePSIG: Zvikamu zveDzvinyiriro, Musiyano, uye Kuchinja
Chii chinonzi PSI?
PSI (Mapaundi paSkweya Inch) inoyera kumanikidzwa nekuverenga simba (mapaundi) rinoshandiswa paskweya inchi imwe chete yenzvimbo. Inonyanya kushandiswa muma hydraulic systems, pressure yematayi, uye michina yeindasitiri, ndiyo yakajairika imperial pressure unit.
Cherechedza: PSI inogona zvakare kureva mari (Initial Coin Offering) kana mushonga (Postpartum Stress Inventory), asi gwaro iri rinotarisa pane zveinjiniya.
PSI sechikamu chekumanikidza
Tsanangudzo
PSI inoyera kumanikidzwa kana simba re 1 lb rikashanda panzvimbo ine 1 in². Ndiyo inonyanya kushandiswa muUS/UK mumabasa einjiniya.
Kuchinja Makiyi
| PSI | kPa | bhawa | MPa |
|---|---|---|---|
| 1 PSI | 6.895 | 0.0689 | 0.00689 |
| 1 atm | 101.3 | 1.013 | 0.1013 |
| Zvakafanana | 1 atm ≈ 14.696 PSI | 1 MPa ≈ 145 PSI |

Chii chinonzi PSIG?
Tsanangudzo yePSIG
PSIG (Mapaundi paSkweya Inch Gauge) inoyera chiyero chekumanikidza—kumanikidzwakana tichienzanisa nekumanikidzwa kwemhepoNdiwo kukosha kunoratidzwa pamagauji mazhinji ekudzvanya.
PSI vs PSIG: Musiyano Mukuru
| Nguva | Rudzi | Nzvimbo yekutarisa | Fomura |
|---|---|---|---|
| PSI | Zvichienderana nemamiriro ezvinhu | Zvinosiyana (kazhinji = PSIG) | Chiyero cheGeneric |
| PSIG | Kumanikidzwa kwegeji | Kumanikidzwa kwemhepo yemunzvimbo | PSIG = PSIA – 14.7 |
| PSIA | Kumanikidzwa kwakazara | Muchina wekudzima mvura zvachose | PSIA = PSIG + 14.7 |
Mienzaniso Inoshanda
Tayi rakanyorwa kuti “35 PSI” = 35 PSIG (geuge pressure).
Chinovhara mvura pagungwa chinoti -14.7 PSIG (PSIA = 0).
PSI vs PSIG: Zvishandiso Zvikuru
Nyaya dzekushandiswa kwemaindasitiri
PSIG:Inoshandiswa muma "pressure gauges", ma "compressor", uye ma "hydraulic systems" (semuenzaniso, kuyera "pressure" yematairi kana "pombi pressure").
PSIA:Zvakakosha muhurongwa hwemhepo/vacuum uko kudzvanywa kwakazara kunokosha.
Kujekeswa Kwehunyanzvi
Magwaro anowanzopfupikisa PSIG se "PSI,"asi mamiriro ezvinhu akaomarara anoda musiyano (semuenzaniso, rondedzero yezviratidzo zvendege "18 PSI" asi zvinoreva 18 PSIG).
Mutemo wepamusoro:Mazhinji e "PSI" ekuverenga eindasitiri chaizvoizvo iPSIG.
Matafura Ekushandura EPSI Akakwana
Kushandurwa kweDhijitari yeDzvinyiriro
| Chikamu | PSI | bhawa | MPa |
|---|---|---|---|
| 1 PSI | 1 | 0.0689 | 0.00689 |
| Bhawa rimwe chete | 14.5 | 1 | 0.1 |
| 1 MPa | 145 | 10 | 1 |
Mamwe Makiyi Ekushandura
1 PSI = 0.0703 kg/cm²
1 kg/cm² = 14.21 PSI
1 atm = 14.696 PSI = 101.3 kPa = 760 mmHg
Mibvunzo Inowanzo bvunzwa: PSI nePSIG
Mubvunzo: PSI yakafanana nePSIg here?
A: Muchokwadi, "PSI" inowanzoreva PSIG (gauge pressure). Muchokwadi, PSI haina kujeka, nepo PSIG ichireva zvishoma.zvakajekazvinoreva kumanikidzwa kwemhepo.
Mubvunzo: Sei mavharuvhu achishandisa PSI ratings?
A: PSI inoratidza kushivirira kwakanyanya kwesimba (*semuenzaniso, vharuvhu yePSI 1000 = 68.95 bar*).
Mubvunzo: Ndinofanira kushandisa PSIA vs PSIG riini?
A: Shandisa PSIG pakuverenga kumanikidzwa kwemidziyo; PSIA pakushandisa vacuum systems kana pakuverenga kwesainzi.
Zvinhu Zvinokosha Zvaunofanira Kuziva
1. PSI = simba pa sikweya inch; PSIG = PSI kana tichienzanisa nekumanikidzwa kwemhepo.
2. Zvizhinji zve "PSI" zvemaindasitiri iPSI (semuenzaniso, kumanikidzwa kwematayi, kuongororwa kwemavharuvhu).
3. Kuchinja kwakakosha: 1 PSI = 0.0689 bar, 1 MPa = 145 PSI.
