Tlhaloso ea PSI le PSIG: Liyuniti tsa Khatello, Liphapang le Liphetoho
PSI ke eng?
PSI (Liponto ka Sekwere sa Inchi) e lekanya khatello ka ho bala matla (liponto) a sebelisoang sebakeng se le seng sa sekwere sa inchi. Haholo-holo e sebelisoa litsamaisong tsa hydraulic, khatello ea mabili le lisebelisoa tsa indasteri, ke yuniti e tloaelehileng ea khatello ea borena.
Ela Hloko: PSI e ka boela ea bua ka lichelete (Tlhahiso ea Chelete ea Pele) kapa meriana (Postpartum Stress Inventory), empa tataiso ena e shebane le maemo a boenjiniere.
PSI e le Yuniti ea Khatello
Tlhaloso
PSI e lekanya kgatello ha matla a 1 lb a sebetsa hodima bokahodimo ba 1 in². E atile haholo US/UK bakeng sa ditshebediso tsa boenjiniere.
Liphetoho tsa Linotlolo
| PSI | kPa | bare | MPa |
|---|---|---|---|
| 1 PSI | 6.895 | 0.0689 | 0.00689 |
| 1 atm | 101.3 | 1.013 | 0.1013 |
| Litekanyo tse lekanang | Atm e le 1 ≈ 14.696 PSI | 1 MPa ≈ 145 PSI |
Mohlala oa Lefatše la Sebele
-WOG e 1000Valve ea Bolo: E bolela valve ea bolo ea PSI ea 1000 = 68.95 bar kapa 6.895 MPa
-AValve ea Ball ea WOG ea 2000: E bolela valve ea bolo ea PSI ea 2000 = 137.9 bar kapa 13.79 MPa
PSIG ke eng?
Tlhaloso ea PSIG
PSIG (Liponto ka Sekwere sa Inch Gauge) e lekanya kgatello ya tekanyo—kgatelloha e bapisoa le khatello ea sepakapakaKe boleng bo bonts'ang ho boholo ba likhakanyo tsa khatello.
PSI khahlanong le PSIG: Liphapang tsa Bohlokoa
| Nako | Mofuta | Ntlha ea Litšupiso | Foromo |
|---|---|---|---|
| PSI | Ho itshetlehile ka moelelo | E fapana (hangata = PSIG) | Yuniti e tloaelehileng |
| PSIG | Khatello ea tekanyo | Khatello ea sepakapaka ea lehae | PSIG = PSIA – 14.7 |
| PSIA | Khatello e feletseng | Phokotso e feletseng ea lephaka | PSIA = PSIG + 14.7 |
Mehlala e Sebetsang
Thaere e ngotsweng “35 PSI” = 35 PSIG (kgatello ya tekanyo).
Sekheo se se nang letho se bophahamong ba lewatle se bala -14.7 PSIG (PSIA = 0).
PSI khahlanong le PSIG: Litšebeliso tsa Bohlokoa
Linyeoe tsa Tšebeliso ea Liindasteri
PSIG:E sebelisoa ho li-gauge tsa khatello, li-compressor, le litsamaiso tsa hydraulic (mohlala, ho lekanya khatello ea mabili kapa khatello ea liphaephe).
PSIA:Bohlokoa litsamaisong tsa lifofane/vacuum moo khatello e felletseng e leng ea bohlokoa.
Litlhaloso tsa Tekheniki
Litokomane hangata li khutsufatsa PSIG e le "PSI,"empa maemo a thata a hloka phapang (mohlala, lethathamo la litlhaloso tsa sefofane "18 PSI" empa le bolela 18 PSIG).
Molao oa bohlokoa:Bongata ba dipalo tsa "PSI" tsa indasteri ha e le hantle ke PSIG.
Litafole tse Felletseng tsa Phetoho ea PSI
Liphetoho tsa Karolo ea Khatello
| Yuniti | PSI | bare | MPa |
|---|---|---|---|
| 1 PSI | 1 | 0.0689 | 0.00689 |
| Bara e le 1 | 14.5 | 1 | 0.1 |
| 1 MPa | 145 | 10 | 1 |
Liphetoho tse ling tsa senotlolo
1 PSI = 0.0703 kg/cm²
1 kg/cm² = 14.21 PSI
Atm e le 1 = 14.696 PSI = 101.3 kPa = 760 mmHg
Lipotso Tse Botsoang Khafetsa: PSI le PSIG
P: Na PSI e tšoana le PSIG?
K: Ha e le hantle, “PSI” hangata e bolela PSIG (kgatello ya tekanyo). Ka botekgeniki, PSI ha e utlwahale hantle, ha PSIG yona e sa utlwahale hantle.ka ho hlakalitšupiso tsa khatello ea sepakapaka.
P: Ke hobane'ng ha li-valve li sebelisa litekanyetso tsa PSI?
A: PSI e bontša mamello e phahameng ka ho fetisisa ea khatello (*mohlala, valve ea PSI ea 1000 = 68.95 bar*).
P: Ke lokela ho sebelisa PSIA khahlanong le PSIG neng?
A: Sebelisa PSIG bakeng sa ho bala khatello ea lisebelisoa; PSIA bakeng sa litsamaiso tsa vacuum kapa lipalo tsa saense.
Lintlha tsa Bohlokoa
1. PSI = matla ka lisenthimithara tse sekwere; PSIG = PSI ha e bapisoa le khatello ea sepakapaka.
2. Bongata ba boleng ba "PSI" ba indasteri ke PSIG (mohlala, khatello ea mabili, litekanyetso tsa li-valve).
3. Liphetoho tse bohlokoa: 1 PSI = 0.0689 bare, 1 MPa = 145 PSI.
