Jack inosimudza sei huremu?

Jack imhando yemidziyo yakareruka uye diki yekusimudza inoshandisa simbi jacking mativi semidziyo inoshanda uye inosimudza zvinhu zvinorema kuburikidza nepamusoro bracket kana pasi claw mukati mekurohwa.Inonyanya kushandiswa mumafekitari, migodhi, zvekufambisa uye mamwe madhipatimendi sekugadzirisa mota uye kumwe kusimudza, rutsigiro uye mamwe mabasa.Chimiro chayo chakareruka uye chakasimba, chinochinjika uye chakavimbika, uye munhu mumwe chete anogona kuitakura nekuishandisa.

Jacks akakamurwa kuita michina uye hydraulic marudzi.Majeki anowanzo shandiswa anosanganisira hydraulic jacks, screw jacks uye magetsi jacks.

Muchidimbu, musimboti wekutanga wehydraulic transmission mutemo waPascal, ndiko kuti, kudzvanywa kwemvura kwese kwese kunoenderana.Muhurongwa hwekuenzanisa, kudzvinyirirwa kunoitwa nepiston diki kudiki, nepo kudzvanywa kunoitwa nepiston hombe zvakare kwakakura, izvo zvinogona kuchengetedza mvura yakamira.Naizvozvo, kuburikidza nekufambiswa kwemvura, kudzvinyirirwa kwakasiyana pamagumo akasiyana kunogona kuwanikwa, uye chinangwa cheshanduko chinogona kuwanikwa.Iyo hydraulic jack inowanzoshandiswa nevanhu inoshandisa iyi musimboti kuwana simba rekutapurirana.

Basic equation ye static pressure (p=p0+ ρ GH), kana iyo yekunze kudzvanywa P0 yemvura iri mugaba rakavharika ichichinja, chero mvura ikaramba iri muchimiro chayo chepakutanga, kudzvanywa chero nguva mumvura kunochinja. nehuwandu hwakafanana, inova iyo static pressure transfer musimboti kana Pascal musimboti.

Kana imwe dzvinyiriro ikaiswa kune imwe piston muhydraulic system, iyo imwechete yekumanikidza increment inogadzirwa pane imwe piston.Kana nzvimbo yepistoni yechipiri yakapetwa ka10 pane yepiston yekutanga, simba rinoshanda papiston yechipiri richawedzera kusvika ka10 pane rekutanga piston, ukuwo kudzvanywa kwemapistoni maviri kuchiri kuenzana.

Iyo screw jack inodhonza mubato kumashure nekudzoka, inodhonza kunze, kureva, inosundira ratchet clearance kuti itenderere, uye giya diki rebevel rinotyaira hombe bevel giya kutenderedza screw yekusimudza, kuti sleeve yekusimudza isimudzwe. kana kuderedzwa kuti uwane basa rekusimudza tension, asi haisi nyore se hydraulic jack.
