Kodi Jack amakweza bwanji kulemera kwake?

Jack ndi mtundu wa zida zonyamulira zopepuka komanso zazing'ono zomwe zimagwiritsa ntchito zida zojambulira zitsulo ngati zida zogwirira ntchito ndikunyamula zinthu zolemetsa kudzera pabulaketi yapamwamba kapena chikhadabo chapansi mkati mwa sitiroko.Amagwiritsidwa ntchito makamaka m'mafakitale, migodi, mayendedwe ndi madipatimenti ena monga kukonza magalimoto ndi kukweza kwina, kuthandizira ndi ntchito zina.Mapangidwe ake ndi opepuka komanso olimba, osinthika komanso odalirika, ndipo munthu m'modzi amatha kunyamula ndikuigwiritsa ntchito.

Jacks amagawidwa mumitundu yamakina ndi ma hydraulic.Ma jacks omwe amagwiritsidwa ntchito nthawi zambiri amaphatikiza ma hydraulic jacks, screw jacks ndi magetsi.

M'malo mwake, mfundo yoyambira yotumizira ma hydraulic ndi lamulo la Pascal, ndiye kuti, kukakamiza kwamadzi kulikonse kumagwirizana.Mu dongosolo lolinganiza, kupanikizika kwa pisitoni yaing'ono kumakhala kochepa, pamene kupanikizika kwa pistoni yaikulu kumakhalanso kwakukulu, komwe kungapangitse madzi kukhala osasunthika.Chifukwa chake, kudzera pakupatsirana kwamadzimadzi, zovuta zosiyanasiyana pazifukwa zosiyanasiyana zitha kupezeka, ndipo cholinga chakusintha chikhoza kukwaniritsidwa.Jack hydraulic jack yomwe imagwiritsidwa ntchito kwambiri ndi anthu amagwiritsa ntchito mfundo iyi kuti akwaniritse kufalitsa mphamvu.

Basic equation of static pressure (p=p0+ ρ GH), pamene kuthamanga kwakunja kwa P0 kwamadzi omwe ali mumtsuko watsekedwa akusintha, bola ngati madziwo amakhalabe m'malo ake okhazikika, kupanikizika kulikonse mumadzimadzi kudzasintha. ndi kuchuluka komweko, komwe ndi mfundo yosinthira kukakamiza kapena mfundo ya Pascal.

Ngati kukakamiza kwina kuyikidwa pa pistoni imodzi mu hydraulic system, kuthamanga komweko kumapangidwa pa pistoni ina.Ngati pisitoni yachiwiri ili kuwirikiza ka 10 kuposa ya pistoni yoyamba, mphamvu imene ikugwira pisitoni yachiwiriyo idzawonjezeka kuwirikiza ka 10 kuposa ya pistoni yoyamba, pamene mphamvu ya pisitoniyo imakhala yofanana.

Screw jack imakoka chogwiriracho mmbuyo ndi mtsogolo, ndikutulutsa chikhadabo, ndiye kuti, imakankhira chilolezo kuti chizungulire, ndipo giya yaying'ono ya bevel imayendetsa giya yayikulu ya bevel kuti izungulire wononga zonyamulira, kuti manja okweza akwezedwe. kapena kutsitsa kuti akwaniritse ntchito yokweza kupsinjika, koma sizophweka ngati jack hydraulic jack.
