Sida loo beddelo Cadaadiska Valve PSI, BAR iyo MPA?

Beddelka PSI iyo MPA, PSI waa unug cadaadis ah, oo lagu qeexo sida pound/inji-jibbaaran ee Ingiriiska, 145PSI = 1MPa, PSI-ga Ingiriisiga waxa loo yaqaan Pounds per square in. P waa Pound, S waa Square, iyo i waa inch.Waxaad ku xisaabin kartaa dhammaan cutubyada leh cutubyo dadweyne:1bar≈14.5PSI, 1PSI = 6.895kpa = 0.06895barYurub iyo Maraykanka iyo waddamo kale ayaa loo isticmaalaa in ay PSI u isticmaalaan unug ahaan.

Shiinaha, waxaan guud ahaan ku qeexnaa cadaadiska gaaska "kg" (halkii "pound").Unugga jirku waa “KG/CM^2″, cadaadiska hal kiilogaraamna waa awoodda hal kiilo ee hal sentimitir oo labajibbaaran.

Unugyada sida caadiga ah dibadda looga isticmaalo waa “PSI”, unugga gaarka ahna waa “LB/In2”, oo ah “pound/inji laba jibaaran”.Unuggani waa sida calaamadda heerkulka (F).

Intaa waxaa dheer, waxaa jira PA (Pascal, hal Newton waxa uu ku yaalaa hal mitir oo laba jibbaaran), KPA, MPA, BAR, milimitirka biyaha, millimitirka meerkuri iyo unugyo kale oo cadaadis ah.

1 Baar (BAR) = 0.1 MPa (MPA) = 100 Knaka (KPA) = 1.0197 kg/ sentimitir laba jibaaran

1 Cadaadiska atmospheric caadiga ah (ATM) = 0.101325 MPA (MPA) = 1.0333 Bar (BAR)

Sababtoo ah kala duwanaanshaha cutubku aad ayuu u yar yahay, waxaad xasuusan kartaa tan:

1 Bar (BAR) = 1 Cadaadiska caadiga ah ee atmospheric (ATM) = 1 kg/ sentimitir laba jibaaran = 100 kiiloo (KPA) = 0.1 MPa (MPA)

Beddelka PSI waa sida soo socota:

1 Cadaadiska atmospheric caadiga ah (ATM) = 14.696 rodol/inch 2 (PSI)

Xiriirka beddelka cadaadiska:

Cadaadiska 1 Bar (BAR) = 10^5 Pa (PA) 1 Dadin/cm 2 (dyn/cm2) = 0.1 Pa (PA)

1 Terr = 133.322 Pa (PA) 1 mm Hg (mmHg) = 133.322 Pa (PA)

1 mm tiirka biyaha (mmh2O) = 9.80665 Pa (PA)

1 Cadaadiska atmospheric injineernimada = 98.0665 kite (KPA)

1 Knipa (KPA) = 0.145 rodol/inji 2 (PSI) = 0.0102 kg/cm 2 (kgf/cm2) = 0.0098 cadaadiska atmospheric (ATM)

1 rodol xoog/inji 2 (PSI) = 6.895 kenta (KPA) = 0.0703 kg/cm 2 (kg/cm2) = 0.0689 Bar (bar) = 0.068 cadaadiska atmospheric (ATM)

1 Cadaadiska jawiga jirka (ATM) = 101.325 Kenpa (KPA) = 14.696 rodol/inji 2 (PSI) = 1.0333 Bar (BAR)

Waxaa jira laba noocalwaaxyada: mid waa nidaamka "cadaadiska magaca ah" ee uu matalo Jarmalka (oo uu ku jiro dalkayga) heerkulka caadiga ah (Shiinaha waa 100 darajo iyo Jarmalku waa 120 darajo).Mid waa "nidaamka cadaadiska kulaylka" ee uu matalo Maraykanku heerkul gaar ah oo heerkul gaar ah.

Waxaa ka mid ah heerkulka iyo nidaamka cadaadiska ee Maraykanka, marka laga reebo 150LB oo ku salaysan 260 darajo, heerarka kale ee dhammaan heerarka waxay ku saleysan yihiin 454 darajo.

250-pound (150PSI = 1MPa) Nambarka 25 kaarboonka birta birta ah wuxuu ahaa 260 darajo, cadaadiska la ogolyahayna wuxuu ahaa 1MPa, cadaadiska isticmaalka heerkulka qolka ayaa aad uga weynaa 1MPa, qiyaastii 2.0MPa.

Sidaa darteed, guud ahaan, heerka cadaadiska magaca ee u dhigma heerka US 150LB waa 2.0MPa, heerka cadaadiska magaca ee u dhigma 300LB waa 5.0MPa iyo wixii la mid ah.

Sidaa darteed, ma beddeli kartid cadaadiska magaca iyo heerka heerkulka iyadoo loo eegayo qaabka isbeddelka cadaadiska.
