Thehydraulic jackamaphatikiza mawu oti "anayi-awiri kukoka chikwi chimodzi" momveka bwino komanso momveka bwino. Jack wamng'ono samalemera kuposa amphaka angapo mpaka khumi ndi awiri amphaka, koma amatha kunyamula matani angapo kapena matani mazana a zinthu zolemera. Ndizodabwitsa kwambiri. Ndiye, mkati mwa hydraulic jack energy ndi chiyani?

Hydraulic jack ndi chopangidwa ndi classical physics. Ngakhale timadabwitsidwa ndi nzeru zaumunthu, ndikofunikira kumvetsetsa mfundo yogwira ntchito ya hydraulic jack. Chifukwa chake lero, ndikupatsani kusanthula kosavuta kuchokera pamalingaliro afizikiki. Ma hydraulic jacks.
Choyamba, tiyenera kumvetsetsa chiphunzitso chapamwamba mu makina akale, ndiko kuti, lamulo la Pascal, lamulo la Pascal, lomwe ndi lamulo la hydrostatics. "Lamulo la Pascal" limati pambuyo pa mfundo iliyonse mu incompressible static fluid imapanga kuwonjezereka kwamphamvu chifukwa cha mphamvu yakunja, kuwonjezeka kwapanikizi kumeneku kudzaperekedwa kumalo onse amadzimadzi osasunthika nthawi yomweyo.

Mkati mwa jack hydraulic jack makamaka ndi mawonekedwe a U pomwe pisitoni yaying'ono imalumikizidwa ndi pisitoni yayikulu komanso yofanana ndi chipangizo cholumikizirana. Kuthamanga kwa hydraulic kwa pistoni yayikulu kumakulitsidwa ndikukankhira cholumikizira chamanja cholumikizidwa ndi pisitoni yaying'ono kusamutsa madziwo ku pistoni yayikulu. Pa nthawiyi, anthu ena sangamvetse. Matani ochepa amphamvu amadalirabe anthu omwe amagwiritsa ntchito kukakamiza komweko kuti amalize kukweza?
Inde sichoncho. Ngati ndi choncho, ndiye kuti mapangidwe a izihydraulic jackzilibe tanthauzo. Amagwiritsa ntchito lamulo la Pascal mu physics. Chiŵerengero cha malo okhudzana ndi ma pistoni akuluakulu ndi ang'onoang'ono kumadzimadzi ndi ofanana ndi chiwerengero cha kuthamanga. Kungoganiza kuti mphamvu padzanja imachulukitsidwa ndi nthawi za 20 pokanikizira chowongolera ku pistoni yaying'ono, ndipo gawo lolumikizana la ma pistoni akulu ndi ang'onoang'ono ndi 20: 1, ndiye kuti kukakamiza kochokera ku pistoni yaying'ono kupita ku pistoni yayikulu kuwirikiza kawiri. mpaka 20 * 20 = 400 nthawi. Timapita kukagwiritsa ntchito kuthamanga kwa 30KG kukanikiza chowongolera chamanja, mphamvu ya pistoni yayikulu ifika 30KG * 400 = 12T.

Kutengerapo kwamphamvu kwapang'onopang'ono, motsatira mfundo ya Pascal, pakhoza kukhala flyover yanthawi yomweyo, kuti mukwaniritse kutembenuka kwamphamvu kwambiri. Ichi ndichifukwa chake jack yaying'ono ya hydraulic ili ndi mphamvu zambiri.
