Yadda ake canza matsi na Valve PSI, BAR da MPA?

PSI da MPA juzu'i, PSI yanki ne na matsa lamba, wanda aka ayyana shi da fam/inci na murabba'in Burtaniya, 145PSI = 1MPa, kuma PSI Turanci ana kiransa Pounds kowane murabba'i a cikin P shine Pound, S Square, kuma ni Inci ne.Kuna iya lissafin duk raka'a tare da raka'a na jama'a:1 bar≈14.5PSI, 1PSI = 6.895kpa = 0.06895barAna amfani da Turai da Amurka da sauran ƙasashe don amfani da PSI azaman naúrar.

A kasar Sin, gabaɗaya muna kwatanta matsa lamba na iskar gas a cikin "kg" (maimakon "lamba").Naúrar jiki ita ce “KG/CM^2″, kuma matsi na kilo ɗaya shine ƙarfin kilogram ɗaya akan santimita murabba'i ɗaya.

Raka'o'in da aka fi amfani da su a ƙasashen waje sune "PSI", kuma takamaiman sashin shine "LB/In2", wanda shine "laba/inci murabba'i".Wannan rukunin yana kama da alamar zafin jiki (F).

Bugu da kari, akwai PA (Pascal, Newton daya yana kan murabba'in mita daya), KPA, MPA, BAR, ginshikin ruwa na millimita, mercury millimeter da sauran raka'o'in matsa lamba.

1 Bar (BAR) = 0.1 MPa (MPA) = 100 Knaka (KPA) = 1.0197 kg/santimita murabba'i

1 Standard atmospheric matsa lamba (ATM) = 0.101325 MPa (MPA) = 1.0333 Bar (BAR)

Saboda bambancin raka'a kadan ne, zaku iya tunawa da wannan:

1 Bar (BAR) = 1 Standard atmospheric pressure (ATM) = 1 kg/square centimeter = 100 kilo (KPA) = 0.1 MPa (MPA)

Juyin PSI shine kamar haka:

1 Standard atmospheric matsa lamba (ATM) = 14.696 fam/inch 2 (PSI)

Alakar canza matsi:

Matsa lamba 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 shafi na ruwa (mmh2O) = 9.80665 Pa (PA)

1 Injiniya na yanayi matsa lamba = 98.0665 kite (KPA)

1 Knipa (KPA) = 0.145 fam/inch 2 (PSI) = 0.0102 kg/cm 2 (kgf/cm2) = 0.0098 matsa lamba na yanayi (ATM)

1 fam ƙarfi/inch 2 (PSI) = 6.895 kenta (KPA) = 0.0703 kg/cm 2 (kg/cm2) = 0.0689 Bar (bar) = 0.068 matsa lamba na yanayi (ATM)

1 Matsin yanayi na jiki (ATM) = 101.325 Kenpa (KPA) = 14.696 fam/inch 2 (PSI) = 1.0333 Bar (BAR)

Akwai nau'i biyu nabawuloli: daya shine tsarin "matsin lamba" wanda Jamus ke wakilta (ciki har da ƙasata) a yanayin zafi na al'ada (a cikin Sin yana da digiri 100 kuma Jamus tana da digiri 120).Ɗaya shine "tsarin matsa lamba" wanda Amurka ke wakilta a wani zazzabi a wani zazzabi.

Daga cikin tsarin zafin jiki da matsa lamba a cikin Amurka, sai dai 150LB dangane da digiri 260, sauran matakan a duk matakan sun dogara ne akan digiri 454.

250-pound (150PSI = 1MPa) No. 25 carbon karfe bawul ya kasance 260 digiri, da kuma yarda danniya ne 1MPa, da kuma amfani danniya a dakin zafin jiki ya fi girma fiye da 1MPa, game da 2.0MPa.

Sabili da haka, gabaɗaya, matakin matsa lamba na ƙima wanda ya dace da ma'aunin Amurka 150LB shine 2.0MPa, kuma matakin matsa lamba na ƙima wanda ya dace da 300LB shine 5.0MPa da sauransu.

Don haka, ba za ku iya canza matsa lamba na ƙididdiga da matakin zafin jiki gwargwadon tsarin canjin matsa lamba ba.
