Shayela Pulley

Incazelo emfushane:

Njengengxenye yokukhishwa kwamandla yesithumeli, i-pulley yokushayela ihlukaniswe yaba izinhlobo ezimbili: I-smooth surface kanye ne-rubber coated surface pulley.Ngaphansi kwesimo samandla aphansi kanye nezinga lokushisa elincane le-ambient, i-pulley ebusweni obushelelezi ingasetshenziswa.Endabeni yendawo enomswakama, amandla aphezulu kanye nokushelela kalula, kufanele kusetshenziswe i-pulley eboshwe ngenjoloba.

I-pulley yekhanda itholakala endaweni lapho umthumeli wempahla ekhipha khona, eyaziwa ngokuthi ukuphela kokuthulula kwesithumeli sebhande.Ngenxa yokuthi ishayela lonke uhlelo, ngokuvamile idinga ijazi elimahhadlahhadla elimboze indawo engaphandle ukuze kwandiswe ukudonsa kwebhande layo.
I-pulley yekhanda ngokuvamile inobubanzi obukhulu kunawo wonke ama-pulleys.Kwesinye isikhathi, uhlelo lungaba ne-pulley engaphezu kweyodwa njenge-pulley yokushayela.I-pulley yokugcina yokukhipha, ngokuvamile ububanzi obukhulu be-roller yokushayela, ibizwa ngokuthi i-head pulley.

Lokhu kutholakala ekugcineni kokulayisha kwesithumeli sebhande.Ngezinye izikhathi kuza nokuma kwephiko ukuhlanza ibhande ngokuvumela izinto eziwela eceleni ezingxenyeni zokusekela.
Kusethaphu elula yokuthutha ibhande, i-pulley yomsila izogxunyekwa kumzila wesitimela ovamise ukugoba ukuvumela ukuqina kwebhande.Kwezinye izinhlelo zokudlulisa amabhande njengoba sizobona, ukuqina kwebhande kushiywa kwenye i-roller ebizwa ngokuthi i-take-up roller.
