N'chifukwa chiyani ma Jack amakweza kulemera kwakukulu ndi khama lochepa?

Chodabwitsa cha "kubweza kwakukulu kwa ndalama zochepa kwambiri" kulipo kulikonse m'moyo wa tsiku ndi tsiku. Hydraulic jack ndi chitsanzo cha "kubwerera kwakukulu kwa ndalama zochepa kwambiri".

Jackyo amapangidwa makamaka ndi chogwirira, maziko, ndodo ya pistoni, silinda ndi mbali zina.Gawo lirilonse limagwira ntchito yofunikira pakugwira ntchito kwa jack yonse, ndipo woyendetsa amangofunika kutulutsa mphamvu yaying'ono kuti anyamule matani angapo a zinthu zolemera.

Chifukwa chomwe zotsatira zake zitha kukwaniritsidwa makamaka chifukwa cha mfundo ziwiri.Mfundo imodzi ndi mfundo yolimbikitsira.Mwa kukanikiza chogwirira cha jack, gawo lathu lomwe timagwira m'manja ndi mkono wamphamvu, ndipo gawo loyang'ana ndi mkono wotsutsa.Kuchuluka kwa chiŵerengero cha mkono wa mphamvu ndi mkono wotsutsa, kuyesetsa kochepa komwe tiyenera kugwira ntchito.

Mfundo yachiwiri ndi kutumiza magiya.Giya yayikulu imayendetsedwa ndi pinion kenako imatumizidwa ku screw kuti iwonjezere torque ndikukwaniritsa zotsatira zopulumutsa ntchito.Kunena zowona, kufalikira kwa magiya ndikusintha kwa mfundo yolimbikitsira.

Ndi chimodzimodzi pansi pa mphamvu yopulumutsa ntchito kawiri ya lever mfundo ndi kufalitsa zida kuti screw jack imabweretsa "zikwapu zinayi kapena ziwiri" mokwanira, ndikuthetsa mavuto ambiri omwe timakumana nawo m'moyo wathu watsiku ndi tsiku ndi ntchito zazikulu.
