Tam sim no, feem ntau ntawm cov tsoos pulleys nyob rau hauv kev ua lag luam yog cam khwb cia hlau los yog steel castings, uas yog kim thiab nyuaj nyob rau hauv tus txheej txheem, thiab tus nqi tiag tiag yog ntau dua li ntawmnylon pulleys.Cov khoom nylon muaj lub peev xwm muaj zog, tab sis tsis zoo hnav tsis kam thiab yooj yim hnav los ntawm steel cables.

Tab sis peb kuj tuaj yeem hloov cov proportions los tsim cov nylon pulleys zoo dua.Tom qab siv cov nylon pulley tshiab, kev pab cuam lub neej ntawm lub pulley tuaj yeem nce los ntawm plaub mus rau tsib zaug, thiab kev pab cuam lub neej ntawm cov hlua hlau hlua tuaj yeem nce li kaum zaug.

Piv nrog cam khwb cia hlau pulleys,nylon pulleysyog 70% sib dua thiab nce ntau lawm efficiency.Nyob rau tib lub sijhawm, nws kuj tseem txhim kho kev ua haujlwm tag nrho ntawm lub tshuab, uas yooj yim rau kev txij nkawm, disassembly thiab sib dhos tsis muaj roj lubricating.

Nylon logmuaj cov yam ntxwv ntawm tsis muaj kev sib txhuam sparks thiab muaj zog kev nyab xeeb kev ua tau zoo, uas tuaj yeem ua tau raws li cov kev xav tau ntawm kev ua haujlwm sab nraum zoov mus ntev.

Txij li thaum xyoo 1970, ntau lub tuam txhab txawv teb chaws crane tau txais nylon pulleys ua cov khoom siv yooj yim ntawm cranes.Tam sim no, peb lub tuam txhab tsis tau tsuas yog muaj pulleys haum rau cranes, tab sis kuj muaj ntau yam nylon khoom haum rau lwm yam lag luam, uas tau txais zoo los ntawm feem ntau tuam txhab uas muag nyob rau hauv kev ua lag luam.

Nylon yog abrasion resistant thiab tsis tsuas yog txo qhov hnyav tag nrho ntawm lub cuab yeej, tab sis kuj tseem tiv thaiv thiab txhawb cov hlau nto.Tam sim no,nylon pulleystau siv dav hauv kev nqa khoom xws li nkoj thiab elevator.
