A: Ukulinganisa okubalulekileyo kuquka: ububanzi bangaphandle (usebenzisa iteyipu yepi okanye ii-caliper ezinkulu, ukulinganisa kwiindawo ezininzi), ubukhulu beflange (ii-caliper), ukudlala nge-radial (isalathisi se-dial esine-pry bar, umkhondo ophakanyisiweyo), ukudlala nge-axial (isalathisi se-dial esine-axial loading), kunye ne-seal gap (ii-feeler gauges). Bhala phantsi imilinganiselo rhoqo ukuze umisele amazinga okuguguleka (mm ngeeyure ezili-1,000).

Q: Ziziphi iimpawu zokuba kuza kufuneka kutshintshwe i-carrier roller?
A: Iimpawu ziquka: ukuvuza okubonakalayo kwesitywina (ubumanzi, inkunkuma eqokelelweyo), ukujikeleza okurhabaxa okuvakalayo ngexesha lokujika ngesandla, ubushushu obuphezulu bokusebenza (obunokubonwa ngokuchukumisa okanye nge-infrared), iingxolo ezingaqhelekanga ngexesha lokusebenza (ukugaya, ukugquma), ukuguguleka kweflange ebonakalayo enemiphetho ebukhali, ukudlala okulinganiselweyo okugqitha iinkcukacha (i-radial ye-4-6 mm), kunye namabala athe tyaba abonisa ukunamathela.

Q: Ngaba iirola zokuthwala izinto zingakhiwa kwakhona okanye ziphinde zenziwe ukuze zisetyenziswe ekumbeni?
A: Ewe, iinkonzo zokwakha ngokutsha ezithembekileyo zingathatha indawo yeebheringi kunye nezitywini, zakha kwakhona ii-treads ezigugileyo kunye neeflanges ngokusebenzisa i-hardfacing (i-arc efakwe emanzini, i-laser cladding), kwaye zibuyisele izinto kwimeko entsha nge-50-70% yexabiso elitsha. I-CQC TRACK iphuhlisa amandla okuphinda ivelise ukuze ixhase iinjongo zozinzo lwabathengi bemigodi.

Q: Imeko yetsheyini yomkhondo ibuchaphazela njani ubomi berola yomthwali?
A: Itshaneli yendlela egugileyo (ukuphakama kwepitch okugqithisileyo okugqitha i-2-3%, iprofayili yereyile egugileyo) ikhawulezisa ukuguguleka kwerola yenkampani ngokutshintsha ijiyometri yoqhagamshelwano kunye nokwandisa umthwalo oguqukayo. Eyona ndlela ilungileyo kushishino icebisa ukuba kutshintshwe iirola kunye netyathanga xa ukuguguleka kwetyathanga kudlula ukuguguleka kwe-2-3%.

Q: Yeyiphi inkqubo efanelekileyo yokugcina iirola ezithwala ezinye izinto kwimisebenzi yokwemba?
A: Gcina kwindawo ecocekileyo neyomileyo ekhuselweyo kwimozulu (kungcono ukugcina ngaphakathi). Gcina kwiphakheji yokuqala ene-desiccant ukuba ikhona. Jikelezisa rhoqo (rhoqo kwiinyanga ezi-3-6) ukuthintela ukubola kwe-brine. Khusela ekungcoleni nasekutshabalaleni kwempembelelo. Landela iingcebiso zomenzi zokugcina ukuze uhlale ixesha elide utywina kwaye uthambise (ngesiqhelo iminyaka emi-2-3).

Olu shicilelo lobuchwephesha lujoliswe kubaphathi bezixhobo abaziingcali, iingcali zokuthenga, kunye nabasebenzi bokulungisa kwimigodi nakwimisebenzi yokwakha enzima. Iinkcukacha kunye neengcebiso zisekelwe kwimigangatho yoshishino kunye nedatha yomenzi ekhoyo ngexesha lokupapashwa. Onke amagama omenzi, iinombolo zenxalenye, kunye neempawu zeemodeli zisetyenziselwa iinjongo zokuchonga kuphela. Soloko ujongana namaxwebhu ezixhobo kunye neengcali zobugcisa ezifanelekileyo ukuze ufumane izigqibo ezithile zesicelo.
