Magawo a chosakaniza riboni amagwira ntchito ngati njira yofunikira kwambiri yolowera posankha zida ndi kapangidwe ka njira. Mu ntchito ya uinjiniya, mawu oti "magawo" amaphatikizapo mbali zitatu zogwirizana koma zosiyana: mphamvu ya volumetric (yomwe imatsimikiza mphamvu yogwiritsira ntchito batch), miyeso yakunja ya geometric (yomwe imatsimikiza malo oyika ndi mutu wofunikira), ndi miyeso ya ziwalo zoyenda mkati (yomwe imatsimikiza kuchuluka kwa kusakaniza ndi kufanana). Pamodzi, mbali zitatuzi zimapanga mawonekedwe athunthu a chosakaniza riboni.
Ⅰ. Zofotokozera za Voliyumu: Miyeso Yodziwika vs. Mphamvu Yeniyeni
Maonekedwe a chitsanzo cha osakaniza riboni nthawi zambiri amadalira kuchuluka konse, komwe kumatanthauza kuchuluka kwa malo amkati mkati mwa chidebe chooneka ngati U cha chipinda chosakaniza, choyezedwa mu malita (L) kapena ma cubic metres (m³). Mafotokozedwe ofanana amayambira pa mitundu ya ma laboratory a malita 50 mpaka mayunitsi a mafakitale a malita 30,000.
Ndikofunikira kusiyanitsa izi ndi kuchuluka kwa ntchito, komwe kumatanthauza kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito panthawi yogwira ntchito. Chifukwa cha kufunika kwa malo omasuka pamwamba omwe amaperekedwa ndi mfundo yosakaniza ya riboni, kuchuluka koyenera kodzaza kwa 40% mpaka 70% ya kuchuluka konse kumalangizidwa, ndi mtengo wamba wa kapangidwe ka 60%. Izi zikutanthauza kuti makina okhala ndi kuchuluka konse kwa 3,000 L ali ndi mphamvu yeniyeni yogwiritsira ntchito batch ya pafupifupi 1,800 L ya zinthu.
Choletsa ichi chimachokera ku mawonekedwe a kapangidwe ka riboni ya screw: pamene riboni zamkati ndi zakunja zikuzungulira, ziyenera kukankhira zinthuzo kuchokera kumapeto onse awiri kupita pakati kapena kuchokera pakati kupita kumapeto onse awiri, pomwe nthawi yomweyo zimapanga radial tumbling. Ngati kuchuluka kwa kudzaza kuli kokwera kwambiri, zinthuzo pamwamba zidzapitirira malire ogwira ntchito a riboni ndipo sizingathe kutenga nawo mbali mu kayendedwe ka convective, zomwe zimakhudza mwachindunji kufanana kwa kusakaniza.
II.Miyeso Yakunja: Kutalika, M'lifupi, Kutalika, ndi Zopinga za Malo
Chosakaniza riboni chili ndi kapangidwe kopingasa, ndipo miyeso yake yakunja imatsimikiziridwa ndi magawo otsatirawa a geometric:
Kutalika (L): Kumatsimikiziridwa ndi kutalika kwa chotengera chosakaniza ndi miyeso ya axial yoyika mbale zomaliza, ma bearing housings, ndi gear reducer
M'lifupi (W): Zimatsimikiziridwa ndi m'lifupi wakunja kwa chidebe chooneka ngati U ndi mawonekedwe a mbali ya chochepetsera mphamvu cha mota ndi giya
Kutalika (H): Kumadalira mtunda wochokera pansi pa chidebecho kupita ku chivundikiro chapamwamba, komanso kutalika kwa kapangidwe ka valavu yotulutsira madzi pansi ndi malo olowera madzi pamwamba.
III.Miyeso ya Zigawo Zosuntha Zamkati: Chidutswa cha Tsamba Lokulungidwa ndi Kutsetsereka
Magawo a kukula kwa masamba a screw okha ndi omwe amatsimikiza mwachindunji kuchuluka kwa ntchito yosakaniza:
Chidutswa chakunja cha tsamba la screw: Chimazindikira kukula kwa kugwedezeka kwa zinthuzo. Chidutswa chakunja chikakhala chachikulu, chimakulanso kwambiri chomwe chimasunthidwa ndi kuzungulira kamodzi. Kawirikawiri, chidutswa chakunja cha tsamba la screw chimakhala chocheperako pang'ono kuposa m'lifupi mwa mkati mwa chidebe chooneka ngati U, pomwe pakati pa tsamba ndi thupi la chidebecho pamakhala pakati pa 3 ndi 10 mm kuti zinthuzo zisatseke.
Pitch: Pitch ya ndege yamkati ndi yakunja ya screw imatsimikizira mtunda wa axial womwe chipangizocho chimakankhidwira ndi kuzungulira kulikonse. Mu mapangidwe anthawi zonse, chiŵerengero cha pitch ndi screw diameter youluka ndi 0.8–1.2. Pitch yaying'ono imapanga mphamvu zolimba zometa, zomwe zimapangitsa kuti ikhale yoyenera zipangizo zomwe zimatha kusonkhana; pitch yayikulu imawonjezera liwiro lotumizira axial, zomwe zimapangitsa kuti ikhale yoyenera zipangizo zomwe zimatha kuyenda bwino.
Ma screw amkati ndi akunja nthawi zambiri amagwiritsa ntchito mawonekedwe awiri, ozungulira motsutsana: ma fly akunja amakankhira zinthuzo kumbali imodzi, pomwe ma fly amkati amakankhira mbali ina, zomwe zimapangitsa kuti zikhale zosakanikirana mu ng'oma yonse. Kusiyana kwa magawo awiriwa a ma fly (m'mimba mwake wamkati nthawi zambiri umakhala nthawi 0.4 mpaka 0.6 kuposa wa kunja) kumapereka mphamvu yoyendetsera zinthu zozungulira.
