Lub twj tso kua mis hydraulic yog lub twj tso kua mis phau ntawv tsim los tsim cov hydraulic siab los ntawm kev tuav haujlwm. Nws yog feem ntau siv los ua lub zog hydraulic lub tog raj kheej, jacks, thiab ntau yam khoom siv hydraulic. Nov yog cov yam ntxwv tseem ceeb thiab cov yam ntxwv ntawm hydraulic tes twj tso kua mis:
Kev tuav haujlwm: Hydraulic tes twj tso kua mis yog ua manually los ntawm tes, ua rau lawv muaj ntau yam thiab tsim nyog rau cov ntawv thov uas siv hluav taws xob, xws li hluav taws xob lossis cua compressed, tej zaum yuav tsis muaj.
Piston lossis Plunger Mechanism: Hydraulic tes twj feem ntau muaj piston lossis plunger mechanism uas, thaum actuated ntawm tes, pressurizes hydraulic kua (feem ntau yog roj) nyob rau hauv lub twj tso kua mis reservoir.
Siab tiam: Raws li tus neeg teb xov tooj twj tso kua mis, hydraulic kua yog hloov chaw, tsim siab. Cov kua dej siab no ces xa mus rau lub tshuab hydraulic, xws li lub tog raj kheej lossis lub jack, ua haujlwm.
