PSI vs PSIG: Kusiyana Kofunika Kwambiri ndi Kutanthauzira Kagwiritsidwe Ntchito

Kufotokozera kwa PSI ndi PSIG: Ma Units Opanikizika, Kusiyana, ndi Kusintha

Kodi PSI ndi chiyani?

PSI (Mapaundi pa Inchi imodzi Yaikulu) imayesa kupanikizika powerengera mphamvu (mapaundi) yomwe imagwiritsidwa ntchito pa inchi imodzi ya malo. Imagwiritsidwa ntchito makamaka mu makina a hydraulic, kuthamanga kwa matayala, ndi zida zamafakitale, ndipo ndiye gawo lodziwika bwino la kuthamanga kwa mphamvu ya Imperial.

Dziwani: PSI ingatanthauzenso zachuma (Chopereka Choyamba cha Ndalama) kapena mankhwala (Postpartum Stress Inventory), koma bukuli likuyang'ana kwambiri pa nkhani za uinjiniya.

PSI ngati Unit Yopanikizika

Tanthauzo

PSI imayesa kuthamanga kwa mphamvu pamene mphamvu ya 1 lb ikugwira ntchito pamalo a 1 in². Ndi yodziwika kwambiri ku US/UK pa ntchito zauinjiniya.

Chitsanzo cha Dziko Lenileni

-WOG 1000Valavu ya Mpira: Zimatanthauza valavu ya mpira ya PSI 1000 = 68.95 bar kapena 6.895 MPa

-AValavu ya Mpira ya WOG ya 2000: Zimatanthauza valavu ya mpira ya PSI ya 2000 = 137.9 bar kapena 13.79 MPa

Kodi PSIG ndi chiyani?

Tanthauzo la PSIG

PSIG (Mapaundi pa Square Inch Gauge) imayesa kupanikizika—kupanikizikapoyerekeza ndi kupsinjika kwa mlengalengaNdi mtengo womwe umawonetsedwa pa magauji ambiri opanikizika.

PSI vs PSIG: Kusiyana Kwakukulu

Zitsanzo Zothandiza

Tayala lolembedwa kuti “35 PSI” = 35 PSIG (kuthamanga koyezera).

Chotsukira madzi pamadzi chimawerengedwa kuti -14.7 PSIG (PSIA = 0).

PSI vs PSIG: Mapulogalamu Ofunika Kwambiri

Milandu Yogwiritsira Ntchito Mafakitale

PSIG:Amagwiritsidwa ntchito mu ma pressure gauges, ma compressor, ndi ma hydraulic systems (monga, kuyeza kuthamanga kwa matayala kapena kuthamanga kwa mapaipi).

PSIA:Chofunika kwambiri mu kayendedwe ka ndege/vacuum komwe kupanikizika kwathunthu ndikofunikira.

Kufotokozera zaukadaulo

Zikalata nthawi zambiri zimafupikitsa PSIG ngati “PSI,”koma nkhani zokhwima zimafuna kusiyanitsa (Mwachitsanzo, mndandanda wa zofotokozera za ndege ndi "18 PSI" koma zikutanthauza 18 PSIG).

Lamulo lalikulu:Mawerengedwe ambiri a "PSI" a mafakitale kwenikweni ndi PSIG.

Matebulo Osinthira a PSI Okwanira

Kusintha kwa Unit Pressure

Kusintha Makiyi Ena

1 PSI = 0.0703 kg/cm²

1 kg/cm² = 14.21 PSI

1 atm = 14.696 PSI = 101.3 kPa = 760 mmHg

Mafunso Ofunsidwa Kawirikawiri: PSI ndi PSIG

Q: Kodi PSI ndi yofanana ndi PSIG?

A: Mwachidule, “PSI” nthawi zambiri imatanthauza PSIG (kuthamanga koyezera). Mwaukadaulo, PSI ndi yosamveka bwino, pomwe PSIG ndi yosiyana ndi mawu ena.momveka bwinozimasonyeza kuthamanga kwa mpweya.

Q: N’chifukwa chiyani ma valve amagwiritsa ntchito ma PSI ratings?

A: PSI imasonyeza kupirira kwamphamvu kwambiri (*monga, valavu ya PSI 1000 = 68.95 bar*).

Q: Ndi liti pamene ndiyenera kugwiritsa ntchito PSIA vs PSIG?

A: Gwiritsani ntchito PSIG powerengera kuthamanga kwa zida; PSIA powerengera makina otayira mpweya kapena mawerengedwe asayansi.

Mfundo Zofunika Kwambiri

1. PSI = mphamvu pa inchi imodzi; PSIG = PSI poyerekeza ndi kupanikizika kwa mpweya.

2. Ma "PSI" ambiri a mafakitale ndi PSIG (monga kuthamanga kwa matayala, ma valvu).

3. Kusintha kofunikira: 1 PSI = 0.0689 bar, 1 MPa = 145 PSI.
