Yi magana game da alakar triangular tsakanin matsa lamba na ƙididdiga, ƙirar ƙira da matsin aiki

1. Menene matsa lamba PN (MPa)?

Ƙimar ma'anar da ke da alaƙa da ƙarfin juriya na matsi na sassan tsarin bututu yana nufin ƙirar da aka ba da matsin lamba da ke da alaƙa da ƙarfin injin na kayan aikin bututu.PN yana bayyana matsi na ƙididdiga gabaɗaya.

(1) Matsin lamba - ƙarfin matsi na samfurin a yanayin zafi, wanda aka bayyana a cikin PN, naúrar: MPa.

(2) Zazzabi na Magana: Abubuwa daban-daban suna da yanayin zafi daban-daban.Misali, yawan zafin jiki na karfe shine 250 ° C

(3) Matsin lamba 1.0Mpa, wanda aka nuna shi azaman: PN 1.0 Mpa

2. Menene damuwar aiki?

Yana nufin matsakaicin matsa lamba da aka ƙayyade bisa ga matsakaicin matsakaicin aiki na bututun da aka isar da shi a kowane matakan don amincin tsarin bututun.Ana bayyana matsi na aiki gabaɗaya a cikin Pt.

3. Menene matsin ƙirar ƙira?

Yana nufin matsakaicin matsa lamba nan take na tsarin bututun ruwa da ke aiki akan bangon ciki na bututun.Gabaɗaya, ana amfani da jimlar matsin aiki da ragowar matsa lamba na guduma na ruwa.Ana bayyana matsa lamba na ƙira gabaɗaya a cikin Pe.

4. Gwajin gwaji

An ƙayyade matsi da za a kai don ƙarfin matsawa da gwajin ƙarfin iska na bututu, kwantena ko kayan aiki.Ana bayyana matsi na gwajin gabaɗaya a cikin Zab.

5. Alakar da ke tsakanin matsa lamba na ƙididdiga, matsa lamba na aiki da matsa lamba na ƙira

Matsin lamba shine matsi na ƙididdiga da aka kayyade don dacewar ƙira, ƙira da amfani.Naúrar wannan matsi na suna a zahiri matsa lamba ne, kuma matsa lamba sunan gama gari ne a cikin Sinanci, sashin kuma shine “Pa” maimakon “N”.Matsin lamba a cikin Ingilishi shine pres-surenomina mara kyau: l a cikin suna ko tsari amma ba a zahiri ba (masu ƙima, ƙima).Matsakaicin matsi na matsi na jirgin ruwa yana nufin matsi na ƙima na flange na jirgin ruwa.The maras muhimmanci matsa lamba flange jirgin ruwa flange ne kullum zuwa kashi 7 maki, wato 0.25, 0.60, 1.00, 1.60, 2.50, 4.00, 6.40MPa.Tsarin ƙira = 1.5 × matsa lamba mai aiki.

Ana samun matsa lamba na aiki daga lissafin hydraulic na cibiyar sadarwar bututu.

6. Dangantaka

Gwajin gwajin> matsa lamba na ƙima>Matsayin ƙira>Matsayin aiki

Tsarin ƙira = 1.5 × matsa lamba aiki (yawanci)
