Jack e phahamisa boima joang?

Jack ke mofuta oa lisebelisoa tsa ho phahamisa tse bobebe le tse nyane tse sebelisang likarolo tsa tšepe tsa jacking joalo ka lisebelisoa tse sebetsang le ho phahamisa lintho tse boima ka borakete e kaholimo kapa ka claw e tlase ka har'a stroke.E sebelisoa haholo lifemeng, merafong, lipalangoang le mafapheng a mang e le ho lokisa likoloi le ho phahamisa tse ling, tšehetso le mesebetsi e meng.Sebopeho sa eona se bobebe ebile se tiile, se tenyetseha ebile se ka tšeptjoa, 'me motho a le mong a ka se jara le ho se sebelisa.

Li-jacks li arotsoe ka mefuta ea mechine le ea hydraulic.Li-jacks tse sebelisoang hangata li kenyelletsa li-hydraulic jacks, li-screw jacks le li-jacks tsa motlakase.

Ha e le hantle, molao-motheo oa phetisetso ea hydraulic ke molao oa Pascal, ke hore, khatello ea metsi hohle e tsitsitse.Tsamaisong ea ho leka-lekana, khatello e hlahisoang ke piston e nyenyane e batla e le nyenyane, ha khatello e hlahisoang ke piston e kholoanyane le eona e batla e le khōlō, e ka bolokang mokelikeli o tsitsitse.Ka hona, ka ho fetisoa ha metsi, likhatello tse fapaneng lipheletsong tse fapaneng li ka fumanoa, 'me morero oa phetoho o ka finyelloa.Jack hydraulic jack e sebelisoang hangata ke batho e sebelisa molao-motheo ona ho fihlela phetisetso ea matla.

Equation ea mantlha ea khatello e tsitsitseng (p=p0+ ρ GH), ha khatello ea kantle ea P0 ea mokelikeli o ka har'a sets'oants'o se koetsoeng e fetoha, ha feela mokelikeli o ntse o le boemong ba oona ba pele, khatello ea nako efe kapa efe ea mokelikeli e tla fetoha. ka tekanyo e lekanang, e leng molao-motheo oa ho fetisa khatello kapa molao-motheo oa Pascal.

Haeba khatello e itseng e sebelisoa ho piston e le 'ngoe tsamaisong ea hydraulic, khatello e tšoanang ea increment e tla hlahisoa piston e' ngoe.Haeba sebaka sa piston ea bobeli e le makhetlo a 10 ho feta piston ea pele, matla a sebetsang piston ea bobeli e tla eketseha ho feta makhetlo a 10 ho feta a piston ea pele, ha khatello ea lipiston tse peli e ntse e lekana.

The screw jack e hula mofeng ho ea pele le pele, e ntša manala, ke hore, e sutumelletsa sebaka sa ratchet hore se potoloha, ebe gear e nyane ea bevel e khanna sekoti se seholo sa bevel ho potoloha sekoti sa ho phahamisa, hore letsoho le phahamisang le phahamisoe. kapa ho theoleloa ho fihlela mosebetsi oa ho phahamisa tsitsipano, empa ha ho bonolo joaloka jack hydraulic.
