Qhov twg yog qhov nrawm dua, ib leeg saw hluav taws xob hoist lossis ob txoj saw?

Ib txoj sawhluav taws xob hoisthais txog ib txoj hlua nqa nqa txuas nrog tus nuv, thaum lub saw ob txhais tau tias ob. Ob txhais tau hais tias ib lub sprocket ntxiv rau qhov sib txuas ntawm lub tshuab hluav taws xob kom tso cai rau ib qho saw hlau hla, uas yog sib npaug rau ob txoj saw txuas. Hooked. Nyob rau hauv ib txwm muaj xwm txheej, lub lifting ceev ntawm ib lub saw hlau yog ceev dua li ntawm ob lub saw fais hoist.

Tus naj npawb ntawm cov chains raug cuam tshuam los ntawm qhov ntsuas load. Feem ntau, 1 tuj yog ib qho saw hlau, 2 tons yog ob txoj saw, lossis 1 tuj kuj tuaj yeem ua ob txoj saw, uas tsis ruaj. Vim hais tias ib lub saw hlau tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom thauj khoom yog tias nws yuav tsum nqa cov nyiaj ntau, cov chains muaj kev sib raug zoo nrog cov khoom thauj. Lub peev xwm nqa thiab nqa ceev ntawm ib qho saw thiab ob lub saw sib txawv. Piv txwv li, lifting ceev ntawm 1 tuj ib leeg saw fais hoist yog 6.6m / min, thaum lub lifting ceev ntawm 1 tuj ob saw yog 3.4m / min. Thiab lub zog lub cev muaj zog kuj txawv. Ib tuj ntawm ib lub saw yog 1.5kw, thaum ib tuj ntawm ob lub saw yog 0.75kw.

Qhov ceev yog txheeb ze rau ntau qhov ntsuas. Piv txwv li, yog hais tias lub lifting hnyav yog lub teeb, lub lifting ceev yuav ceev. Yog hais tias lub cev muaj zog lifting ntawm ib tug loj tonnage muaj zog thiab cov xov tooj ntawm chains loj, lub lifting ceev yuav tsis ceev heev, thiab txawm tias nws yog ceev, nws yuav tsis muaj kev ruaj ntseg txaus. , nws yooj yim rau co thiab instability. Ntxiv nrog rau cov saw hoists, hlau hlua hluav taws xob hoists yeej yog txoj cai. Lawv kuj tau muab faib ua ib qho ceev thiab ob zaug ceev. Qhov ceev tuaj yeem hloov kho yog tias muaj qee qhov yuav tsum tau ua, xws li xaiv cdmd nrog cov nrawm sib txawv, lossis hloov pauv ceev thiab zaus.
