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

Juyawar PSI da MPA, PSI na'urar matsi ce, wadda aka ayyana a matsayin fam/murabba'in inci na Burtaniya, 145PSI = 1MPa, kuma ana kiran PSI Turanci fam a kowace murabba'in inci. P fam ne, S murabba'i ne, kuma i Inci ne. Kuna iya ƙididdige duk raka'o'in da ke da raka'o'in jama'a:Sanduna 1≈14.5PSI, 1PSI = 6.895kpa = 0.06895sandunaTurai da Amurka da sauran ƙasashe suna amfani da PSI a matsayin naúrar.

A ƙasar Sin, galibi muna kwatanta matsin lambar iskar gas a cikin "kg" (maimakon "fam"). Naúrar jiki ita ce "KG/CM^2″, kuma matsin lambar kilogram ɗaya shine ƙarfin kilogram ɗaya akan murabba'in santimita ɗaya.

Na'urorin da aka fi amfani da su a ƙasashen waje sune "PSI", kuma takamaiman na'urar ita ce "LB/In2", wanda shine "pound/square inci". Wannan na'urar tana kama da alamar zafin jiki (F).

Bugu da ƙari, akwai PA (Pascal, Newton ɗaya yana kan murabba'in mita ɗaya), KPA, MPA, BAR, ginshiƙin ruwa na milimita, millimeter mercury da sauran na'urorin matsi.

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

1 Matsakaicin matsin lamba a yanayi (ATM) = 0.101325 MPa (MPA) = 1.0333 Bar (BAR)

Saboda bambancin na'urar yana da ƙanƙanta sosai, za ku iya tuna wannan:

Sanduna 1 (SANDA) = 1 Matsakaicin matsin lamba na yanayi (ATM) = 1 kg/santimita murabba'i = kilogiram 100 (KPA) = 0.1 MPa (MPA)

Canza PSI kamar haka:

1 Matsakaicin matsin lamba na yanayi (ATM) = fam 14.696/inch 2 (PSI)

Alaƙar 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)

Ginshiƙin ruwa na mm 1 (mmh2O) = 9.80665 Pa (PA)

1 Matsin yanayi na injiniya = 98.0665 kite (KPA)

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

Ƙarfin fam 1/inci 2 (PSI) = 6.895 kenta (KPA) = 0.0703 kg/cm 2 (kg/cm2) = 0.0689 Bar (sanduna) = 0.068 matsin lamba na yanayi (ATM)

1 Matsi na zahiri a yanayi (ATM) = 101.325 Kenpa (KPA) = fam 14.696/inch 2 (PSI) = 1.0333 Bar (BAR)

Akwai nau'i biyu nabawuloli: ɗaya ita ce tsarin "matsin lamba na musamman" wanda Jamus (har da ƙasata) ke wakilta a yanayin zafi na yau da kullun (a China digiri 100 ne kuma Jamus digiri 120 ne). Ɗaya ita ce "tsarin matsin lamba na zafin jiki" wanda Amurka ke wakilta a wani yanayin zafi a wani yanayin zafi.

Daga cikin tsarin zafin jiki da matsin lamba a Amurka, banda 150LB bisa digiri 260, sauran matakan a kowane mataki sun dogara ne akan digiri 454.

Bawul ɗin ƙarfe mai nauyin fam 250 (150PSI = 1MPa) mai lamba 25 ya kasance digiri 260, kuma matsin lambar da aka yarda da ita shine 1MPa, kuma matsin lambar amfani da shi a zafin ɗaki ya fi 1MPa girma, kimanin 2.0MPa.

Saboda haka, gabaɗaya, matakin matsin lamba na asali wanda ya yi daidai da ma'aunin Amurka na 150LB shine 2.0MPa, kuma matakin matsin lamba na asali wanda ya yi daidai da 300LB shine 5.0MPa da sauransu.

Saboda haka, ba za ku iya canza matsin lamba da matakin zafin jiki bisa ga dabarar canza matsin lamba ba.
