Inkcazo ye-PSI kunye ne-PSIG: Iiyunithi zoxinzelelo, umahluko, kunye nokuguqulwa
Yintoni iPSI?
I-PSI (iiponti nge-intshi yesikwere) ilinganisa uxinzelelo ngokubala amandla (iiponti) asetyenziswa kwindawo enye yesikwere se-intshi. Isetyenziswa kakhulu kwiinkqubo ze-hydraulic, uxinzelelo lwamatayara, kunye nezixhobo zoshishino, yiyunithi yoxinzelelo oluqhelekileyo lwe-imperial.
Qaphela: I-PSI isenokubhekisa kwi-finance (Initial Coin Offering) okanye amayeza (Postpartum Stress Inventory), kodwa esi sikhokelo sigxile kwiimeko zobunjineli.
I-PSI njengeCandelo loXinzelelo
Inkcazo
I-PSI ilinganisa uxinzelelo xa i-1 lb yamandla isebenza kumphezulu we-1 in². Isetyenziswa kakhulu e-US/UK kwizicelo zobunjineli.
Ukuguqulwa Okubalulekileyo
| I-PSI | kPa | ibha | I-MPa |
|---|---|---|---|
| 1 PSI | 6.895 | 0.0689 | 0.00689 |
| 1 i-atm | 101.3 | 1.013 | 0.1013 |
| Ezilinganayo | I-atm e-1 ≈ 14.696 PSI | I-MPa e-1 ≈ 145 PSI |
Umzekelo Wehlabathi Lokwenyani
-I-WOG eyi-1000Ivalvu yeBhola: Kuthetha ivalvu yebhola yePSI eyi-1000 = i-68.95 bar okanye i-6.895 MPa
-AIvalvu yeBhola yeWOG ka-2000: Kuthetha ivalvu yebhola yePSI engama-2000 = 137.9 bar okanye 13.79 MPa
Yintoni iPSIG?
Inkcazo yePSIG
I-PSIG (iiponti nge-Square Inch Gauge) ilinganisa i-gauge pressure—pressurexa kuthelekiswa noxinzelelo lomoyaLixabiso eliboniswa kwiigeyiji ezininzi zoxinzelelo.
I-PSI vs i-PSI: Umahluko oPhambili
| Ixesha | Uhlobo | Indawo yokubhekisa | Ifomula |
|---|---|---|---|
| I-PSI | Kuxhomekeke kumxholo | Iyahluka (rhoqo = iPSIG) | Iyunithi yeGeneric |
| I-PSIG | Uxinzelelo lwegeyiji | Uxinzelelo lomoya lwendawo | I-PSIG = I-PSIA – 14.7 |
| I-PSIA | Uxinzelelo olupheleleyo | I-vacuum epheleleyo | I-PSIA = I-PSIG + 14.7 |
Imizekelo Esebenzayo
Itayara ebhalwe “35 PSI” = 35 PSIG (uxinzelelo lokulinganisa).
I-vacuum elwandle ifundeka ngo -14.7 PSIG (PSIA = 0).
I-PSI vs i-PSIG: Izicelo eziphambili
Amatyala okusetyenziswa kwimizi-mveliso
I-PSIG:Isetyenziswa kwiigeyiji zoxinzelelo, iicompressor, kunye neenkqubo zehydraulic (umz., ukulinganisa uxinzelelo lwamatayara okanye uxinzelelo lwepayipi).
I-PSIA:Kubalulekile kwiinkqubo zeenqwelo-moya/zomoya apho uxinzelelo olupheleleyo lubalulekile khona.
Iingcaciso zoBugcisa
Amaxwebhu adla ngokufinyeza i-PSI njenge-“PSI,”kodwa iimeko ezingqongqo zifuna umahluko (Umzekelo, uluhlu lweenkcukacha zeenqwelo-moya oluthi “18 PSI” kodwa luthetha ukuba yi-18 PSIG).
Umgaqo kabhontsi:Uninzi lwezibalo ze-"PSI" zemizi-mveliso ngokwenene yiPSIG.
Iitafile zoGuqulo lwePSI eziBanzi
Ukuguqulwa kweCandelo loXinzelelo
| Iyunithi | I-PSI | ibha | I-MPa |
|---|---|---|---|
| 1 PSI | 1 | 0.0689 | 0.00689 |
| Ibha e-1 | 14.5 | 1 | 0.1 |
| I-MPa e-1 | 145 | 10 | 1 |
Ezinye iinguqu ezibalulekileyo
I-PSI e-1 = 0.0703 kg/cm²
1 kg/cm² = 14.21 PSI
I-atm e-1 = 14.696 PSI = 101.3 kPa = 760 mmHg
Imibuzo ebuzwa rhoqo: i-PSI kunye ne-PSIG
Q: Ingaba i-PSI iyafana ne-PSI?
A: Ngokwenyani, igama elithi “PSI” lidla ngokuthetha iPSIG (uxinzelelo lokulinganisa). Ngokwenyani, iPSI ayicacanga, ngelixa iPSIG ithetha into engacacanga.ngokucacileyoiireferensi zoxinzelelo lomoya.
Q: Kutheni iivalvu zisebenzisa i-PSI ratings?
A: I-PSI ibonisa ukunyamezela koxinzelelo oluphezulu (*umz., ivalvu ye-PSI eyi-1000 = 68.95 bar*).
Q: Ndingayisebenzisa nini i-PSIA vs i-PSIG?
A: Sebenzisa i-PSIG xa ufunda uxinzelelo lwezixhobo; i-PSIA xa usebenzisa i-vacuum systems okanye xa usebenzisa izibalo zesayensi.
Izinto ezibalulekileyo ekufuneka ziqwalaselwe
1. I-PSI = amandla nge-intshi yesikwere; I-PSI = I-PSI xa ithelekiswa noxinzelelo lomoya.
2. Uninzi lwexabiso le-"PSI" kwimizi-mveliso yi-PSI (umz., uxinzelelo lwamatayara, ukulinganiswa kweevalvu).
3. Ukuguqulwa okubalulekileyo: 1 PSI = 0.0689 bar, 1 MPa = 145 PSI.
