Sharaxaadda PSI iyo PSIG: Cutubyada Cadaadiska, Kala Duwanaanshaha, iyo Beddelka
Waa maxay PSI?
PSI (Pounds halkii Injin Labajibbaaran) waxay cabbirtaa cadaadiska iyadoo xisaabinaysa xoogga (pounds) ee lagu dabaqay hal inji labajibbaaran oo bedka ah. Asal ahaan waxaa loo isticmaalaa nidaamyada haydarooliga, cadaadiska taayirada, iyo qalabka warshadaha, waa cutubka cadaadiska boqortooyada caadiga ah.
Fiiro gaar ah: PSI waxay sidoo kale tixraaci kartaa maaliyadda (Bixinta Lacagta Bilowga ah) ama daawada (Bandhigga Walbahaarka Dhalmada Kadib), laakiin hagahani wuxuu diiradda saarayaa duruufaha injineernimada.
PSI oo ah Cutub Cadaadis ah
Qeexitaan
PSI waxay cabbirtaa cadaadiska marka 1 lb oo xoog ah uu ku shaqeeyo dusha sare ee 1 in². Waa mid aad ugu badan Mareykanka/UK marka loo eego codsiyada injineernimada.
Beddelka Muhiimka ah
| PSI | kPa | baar | MPA |
|---|---|---|---|
| 1 PSI | 6.895 | 0.0689 | 0.00689 |
| 1 atm | 101.3 | 1.013 | 0.1013 |
| U dhigma | 1 atm ≈ 14.696 PSI | 1 MPa ≈ 145 PSI |
Tusaale Dhab ah
-1000 WOGQalabka Kubadda: Waxay la macno tahay 1000 PSI ball waalka = 68.95 bar ama 6.895 MPa
-A2000 WOG Ball Valve: Waxay ka dhigan tahay 2000 PSI ball waalka = 137.9 bar ama 13.79 MPa
Waa maxay PSIG?
Qeexitaanka PSIG
PSIG (Roond halkii Inji oo Labajibbaaran ah Cabbirka) wuxuu cabbiraa cadaadiska cabbirka - cadaadiskamarka loo eego cadaadiska jawigaWaa qiimaha lagu soo bandhigo inta badan cabbirayaasha cadaadiska.
PSI vs PSIG: Kala duwanaanshaha Muhiimka ah
| Muddada | Nooca | Barta Tixraaca | Qaaciddada |
|---|---|---|---|
| PSI | Ku-tiirsanaan Macnaha guud | Kala duwan (badanaa = PSIG) | Cutubka guud |
| PSIG | Cadaadiska cabbirka | Cadaadiska jawiga deegaanka | PSIG = PSIA – 14.7 |
| PSIA | Cadaadis buuxa | Faaruq dhammaystiran | PSIA = PSIG + 14.7 |
Tusaalooyin wax ku ool ah
Taayir lagu calaamadeeyay "35 PSI" = 35 PSIG (cadaadis cabbir).
Faakuumka heerka badda wuxuu u dhigmaa -14.7 PSIG (PSIA = 0).
PSI iyo PSIG: Codsiyada Muhiimka ah
Kiisaska Isticmaalka Warshadaha
PSIG:Waxaa loo isticmaalaa cabbirayaasha cadaadiska, kombaresarada, iyo nidaamyada haydarooliga (tusaale ahaan, cabbiraadda cadaadiska taayirka ama cadaadiska dhuumaha).
PSIA:Muhiim u ah nidaamyada hawada sare/vacuum-ka halkaas oo cadaadiska dhabta ah uu muhiim yahay.
Caddeynta Farsamada
Dukumentiyadu waxay inta badan PSIG u soo gaabiyaan "PSI,"laakiin xaaladaha adag waxay u baahan yihiin kala soocid (tusaale ahaan, liiska faahfaahinta diyaaradaha "18 PSI" laakiin macnaheedu waa 18 PSIG).
Xeerka suulka:Inta badan akhrinta "PSI" ee warshadaha ayaa dhab ahaantii ah PSIG.
Jadwallada Beddelka PSI ee Dhammaystiran
Beddelka Cutubka Cadaadiska
| Cutubka | PSI | baar | MPA |
|---|---|---|---|
| 1 PSI | 1 | 0.0689 | 0.00689 |
| 1 baar | 14.5 | 1 | 0.1 |
| 1 MPa | 145 | 10 | 1 |
Beddelaadyo kale oo Muhiim ah
1 PSI = 0.0703 kg/cm²
1 kg/cm² = 14.21 PSI
1 atm = 14.696 PSI = 101.3 kPa = 760 mmHg
Su'aalaha Badiya La Weydiiyo: PSI iyo PSIG
S: PSI ma la mid baa PSIG?
A: Dhab ahaantii, "PSI" badanaa waxay tilmaamaysaa PSIG (cadaadis cabbir). Farsamo ahaan, PSI waa mid aan caddayn, halka PSIG ay tahay mid aan caddayn.si cadtixraaca cadaadiska jawiga.
S: Maxay waalayaashu u isticmaalaan qiimeynta PSI?
A: PSI waxay muujinaysaa dulqaadka cadaadiska ugu badan (*tusaale ahaan, 1000 PSI valv = 68.95 bar*).
S: Goorma ayaan isticmaali karaa PSIA iyo PSIG?
A: U isticmaal PSIG akhrinta cadaadiska qalabka; PSIA nidaamyada faakuumka ama xisaabinta sayniska.
Waxyaabaha Muhiimka ah ee Laga Qaadan Karo
1. PSI = xoog inji laba jibbaaran ah; PSIG = PSI marka loo eego cadaadiska jawiga.
2. Qiimaha ugu badan ee warshadaha "PSI" waa PSIG (tusaale ahaan, cadaadiska taayirka, qiimeynta waalka).
3. Beddelaadyo muhiim ah: 1 PSI = 0.0689 bar, 1 MPa = 145 PSI.
