Molao oa Pascal le Sisteme ea Hydraulic
Tlhaloso e Bonolo ea Molao oa Pascal
Molao oa Pascal o theha motheo oa sistimi e 'ngoe le e 'ngoe ea haeteroliki. Molao ona o re ha motho a sebelisa khatello mokelikeling o koetsoeng, khatello e ata ka ho lekana mahlakoreng 'ohle. Khatello ha e fokotsehe kapa ha e fetohe ha e ntse e tsamaea ka har'a mokelikeli. Sena se bolela hore matla a sebelisoang ntlheng e 'ngoe tsamaisong a ka hlahisa phello e lekanang ntlheng e 'ngoe, leha libopeho kapa boholo ba lijana li fapane.
Bo-rasaense ba lekile Molao oa Pascal ka liteko tse ngata. Pontšo e 'ngoe e tummeng ke Teko ea Pascal ea Barrel. Tekong ena, motho o tšela metsi ka har'a phaephe e telele, e tšesaane e hokahantsoeng le barele e tletseng metsi. Esita le metsi a manyane ka har'a phaephe a baka khatello e lekaneng ho phatlola barele. Sena se bontša hore khatello e sebelisoang holimo e tsamaea ka ho lekana ho pholletsa le mokelikeli, ho sa tsotelehe sebopeho kapa boholo ba setshelo.

Foromo ea lipalo bakeng sa Molao oa Pascal ke:
P = F / Amoo P e emetseng kgatello, F e emetseng matla, le A e emetseng sebaka. Haeba motho a sebedisa matla piston e nyane, kgatello e hlahiswang e tshwana ho pholletsa le mokelikeli. Ha kgatello ena e fihla piston e kgolo, matla a a eketseha hobane sebaka se seholo. Molao-motheo ona o dumella sistimi ya hydraulic ho atisa matla le ho etsa mesebetsi e boima ka boiteko bo bonyenyane.
Mohlala oa Letsatsi le Letsatsi oa Molao oa Pascal

Ha mochini o sutumelletsa lever e nyane fatše, matla a tsamaea ka har'a mokelikeli oa hydraulic 'me a phahamisa koloi e boima. Khatello e hlahisoang ke matla a manyane a ho kenya e hasana ka ho lekana ka har'a mokelikeli, e leng se lumellang piston e kholo ho phahamisa koloi habonolo.

Ho Sebelisa Liforomo ho Bala Matla
Lipalo tse sebetsang li thusa basebelisi ho utloisisa hore na liforomo li sebetsa joang lits'ebetsong tsa 'nete tsa hydraulic. Nahana ka mehlala ena:
- Silindara ea hydraulic e na le bophara ba piston ba lisenthimithara tse 4 'me e sebetsa ho 1500 PSI.
- Radius = lisenthimithara tse 2
- Sebaka = π × (2 inches)^2 ≈ 12.57 square inches
- Matla = 1500 PSI × 12.57 lisekoere-inchi ≈ 18,855 liponto
- Silindara e nyane e bophara ba lisenthimithara tse 2 ka khatello e tšoanang:
- Radius = 1 inch
- Sebaka = π × (inchi e le 1)^2 ≈ 3.14 lisekoere-inchi
