Ngongole yamphamvu pulley block

Kuwala kwa buluzi kwamphamvu ndi gawo lalikulu la makina omangira anga, makamaka opangidwa ndi ma pulleys, mabatani, mabatani ndi zida zamafuta. Ntchito yake yolumikizira ndikuwongolera katunduyo ndikuchepetsa katundu wam'munda posintha njira ya waya kuti iwonetsetse mayendedwe otetezeka komanso ogwira ntchito. Chitseko cha mazira nthawi zambiri chimapangidwa ndi chitsulo champhamvu kapena chovala chosagwirizana ndi chitsulo chosokoneza chilengedwe komanso katundu wolemera.

Malinga ndi masanjidwewo, pulley block imatha kugawidwa mu sheve (yokhazikitsidwa pamwamba pa derrick) ndi gudumu lotsogolera (lomwe limagwiritsidwa ntchito kusintha waya wayandama). Sheing imagwiritsidwa ntchito kwambiri pa shaft yolumikizira ndikukhala ndi katundu wofutukuka; Wheel wowongolera nthawi zambiri amapezeka mu shafts kapena zikwangwani zovuta ndipo amafunika kukhala ndi njira zotsutsana ndi zoyeserera. Mitundu ina yapamwamba kwambiri imakhalanso ndi masensa kuti muwunikire mawaya minda yovuta komanso yovala zamkati munthawi yeniyeni kuti musinthe chitetezo.

Kuyang'ana kuvala kovuta kwa tchire la tchireli, kudyetsa mafuta ndi mawonekedwe achangu ndiye njira yowonetsetsa kuti apange ntchito yabwino. Malo obisika amakhala dzimbiri komanso kudzikundikira kwafumbi, ndipo mapepala osindikizidwa ndi mafuta odzola okhaokha amafunikira. Ngati kuvala chingwe kapena ming'alu mu pulley kupezeka, makinawo ayenera kuyimitsidwa ndikusinthidwa mwachangu kuti apewe ngozi zankhondo. Kuphatikiza apo, kapangidwe ka akabulule yaphulu kuyenera kutsatira zinthu zachitetezo ku National.
