Q: Ingabe ama-roller okuthwala angakhiwa kabusha noma akhiqizwe kabusha ukuze kusetshenziswe ukumba?
A: Yebo, izinsizakalo zokwakha kabusha ezithembekile zingathatha indawo yama-bearings nama-seal, zakha kabusha ama-treadmill agugile nama-flanges ngokusebenzisa i-hardfacing (i-arc ecwiliswe emanzini, i-laser cladding), futhi zibuyisele izingxenye esimweni esifanayo ngezindleko ezintsha ezingama-50-70%. I-CQC TRACK ithuthukisa amakhono okuvuselela kabusha ukusekela imigomo yokusimama kwamakhasimende okumba.

U: Isimo se-track chain sithinta kanjani impilo ye-carrier roller?
A: Uchungechunge lwethrekhi olugugile (ukunwebeka kwephimbo ngokweqile okungaphezu kuka-2-3%, iphrofayili yesitimela esigugile) kusheshisa ukuguguleka kweroli yokuthwala ngokushintsha i-geometry yokuxhumana nokwandisa umthwalo oguquguqukayo. Umkhuba omuhle kakhulu wemboni uncoma ukushintsha amaroli kanye neketanga ndawonye lapho ukuguguleka kweketanga kudlula ukunwebeka kuka-2-3%.

Q: Iyiphi inqubo efanele yokugcina ama-rollers okuthwala ayisipele emisebenzini yezimayini?
A: Gcina endaweni ehlanzekile, eyomile, evikelekile esimweni sezulu (kungcono ukugcina ngaphakathi). Gcina ephaketheni lokuqala eline-desiccant uma litholakala. Jikelezisa njalo (njalo ezinyangeni ezi-3-6) ukuvimbela ukubola kwe-brine. Vikela ekungcoleni nasekulimaleni komthelela. Landela izincomo zomkhiqizi zokugcina ukuze kube nokuphila isikhathi eside kokuvala nokugcoba (ngokuvamile iminyaka emi-2-3).

Le ncwadi yobuchwepheshe ihloselwe abaphathi bemishini abangochwepheshe, ochwepheshe bokuthenga, kanye nabasebenzi bokulungisa ezimayini nasemisebenzini yokwakha enzima. Imininingwane kanye nezincomo kusekelwe ezindinganisweni zemboni kanye nedatha yomkhiqizi etholakala ngesikhathi sokushicilela. Wonke amagama omkhiqizi, izinombolo zezingxenye, kanye nezimpawu zamamodeli kusetshenziselwa izinjongo zokuhlonza kuphela. Njalo bheka imibhalo yemishini kanye nochwepheshe bezobuchwepheshe abafanelekayo ukuze uthole izinqumo eziqondene nesicelo.
