I. Akamaro ko guhitamo iminyururu n'amapine bikwiye
Mu nganda za sima, ascenseur zo mu ndobo ni ingenzi cyane mu gutwara ibikoresho biremereye kandi bikurura cyane nka clinker, limestone, na sima mu buryo buhagaze.Iminyururu n'iminyururu by'uruzigaBifite umuvuduko ukomeye mu by'ikoranabuhanga, bigatuma imiterere yabyo n'uburyo bigenzura umusaruro ari ingenzi kugira ngo imikorere igende neza. Dore impamvu guhitamo ibice bikwiye ari ingenzi n'uburyo SCIC ibikemura:
1. Ubushobozi bwo gutwara imizigo:Iminyururu n'iminyururuIgomba kwihanganira imitwaro myinshi yo gukurura no guhungabana bitewe no kugenda kw'indobo mu buryo buhoraho. Ibice bidafite ubuziranenge bishobora kwangirika bitunguranye, bigatera ikibazo cyo kudakora neza, ibyago by'umutekano, no gusana bihenze. Kuba SCIC ikurikiza amahame ya DIN bituma ibicuruzwa byacu byuzuza ibisabwa by'imbaraga, nko kugabanya imbaraga zavuzwe za 280–300 N/mm².
2. Kurwanya kwangirika: Imiterere y'ibikoresho bya sima yoroshye cyane yihutisha kwangirika kw'ibice bya ascenseur. Iminyururu ikonje (kugeza kuri 800 HV) n'iminyururu (kugeza kuri 600 HV) bitanga ubuso burambye bwo kwirinda kwangirika, mu gihe bikomeza gukomera kugira ngo hirindwe kwangirika. Uburyo bwo gushyira kaburimbo neza bwa SCIC bugera ku bunini bwa 10% bya kaburimbo busabwa n'ubujyakuzimu bungana na 5–6%, bigatuma bikora neza igihe kirekire.
3. Iyubahirizwa ry'amahame ngenderwaho: Iyubahirizwa rya DIN 764, DIN 766, DIN 745, na DIN 5699 ryemeza koiminyururu n'iminyururukuzuza ibipimo ngenderwaho by’inganda ku bipimo, imiterere y’ibikoresho, n’ubwizerwe. Ubuhanga bwa SCIC mu kuzuza aya mahame butuma habaho ireme rihoraho rijyanye n’imirimo ikomeye.
4. Igenzura ry’Ubuziranenge bw’Umusaruro: Igenzura rikomeye rya SCIC—kuva ku guhitamo ibikoresho kugeza ku igenzura rya nyuma—rigabanya inenge kandi rigatuma imiterere y’ibikoresho iba myiza, ikomeye kandi ikomeye. Ubu bushobozi bugabanya ibyago byo kwangirika mu gihe cy’imimerere mibi y’inganda za sima.
Guhitamo igikwiyeiminyururu n'iminyururuni ingenzi cyane ku mikorere myiza n'umutekano wa ascenseur zawe zo mu isanduku. Muri SCIC, ibicuruzwa byacu byakozwe kandi bigakorwa kugira ngo byuzuze amahame ya DIN akomeye, bigamije ko bishobora kwihanganira imitwaro iremereye n'ibikoresho byoroshye bikunze gukoreshwa mu nganda za sima. Dukoresheje uburyo bwacu bwo kugenzura ubuziranenge, ushobora kwizera ko iminyururu n'amapine byacu bizatanga umusaruro wizewe, bikagabanya ibyago byo kwangirika gutunguranye n'amafaranga yo kubungabunga.
II. Kunganya Ubukomere n'Imbaraga mu gihe cyo gukora
Kugira ngo umuntu agere ku bukomere bw'ubuso bwemejwe n'umukiriya (800 HV ku minyururu, 600 HV ku minyururu), ubugari bwa kaburiziyo (10% by'umurambararo w'umuyoboro), uburebure bufatika bw'ubukomere (550 HV kuri 5-6% by'umurambararo), n'imbaraga zo gucika (280–300 N/mm²) bisaba uburinganire bwiza hagati y'ubukomere n'imbaraga. Dore uko SCIC ibigeraho binyuze mu guhitamo ibikoresho, kuvura ubushyuhe, no kuvura kaburiziyo:
Uburyo bw'ingenzi bwo gukora
1. Guhitamo ibikoresho:Ibyuma bifite karuboni nyinshi cyangwa alloy bitoranywa bitewe n'ubushobozi bwabyo bwo gusubiza kaburimbo no kuzimya, bigatuma ubuso bukomera kandi bukagira imbaraga nyinshi.
2. Guhindura kaburimbo:Kaburizing ikwirakwiza karuboni mu cyuma kugira ngo yongere ubukana. Ku muyoboro w'uruhererekane ufite umurambararo wa mm 20;Ubujyakuzimu bwa kaburizi: 10% bya mm 20 = mm 2;Ubujyakuzimu bw'ubukomere bukora neza: 5–6% bya mm 20 = mm 1–1.2 kuri 550 HV;Ibi bituma ubuso bukomera kandi budashobora kwangirika mu gihe bibungabunga igice cy'imbere cy'umuyoboro kugira ngo gishobore kwakira imizigo ihindagurika.
3. Uburyo bwo kuvura ubushyuhe:Kuzimya: Nyuma yo kuzimya, ibice birazimwa kugira ngo bifatanye n'ubukomere bw'ubuso (800 HV ku minyururu, 600 HV ku minyururu);Gushyushya: Gushyushya bigenzurwa (urugero, kuri 200–250°C) bihindura imiterere y'inyuma y'umubiri, bigatuma imbaraga zigomba gucikamo 280–300 N/mm². Gushyushya bikabije bigabanya ubukana, mu gihe gushyushya bigabanya ubukana bishobora gutuma umuntu adashyuha.
4. Itegeko ryo kuringaniza: Ubukomere: Ubukomere bwinshi bw'ubuso burwanya kwangirika kw'ibikoresho byoroshye;Ingufu: Gukomera kw'imbere birinda kuvunika kw'ingufu mu gihe cy'imitwaro iremereye.SCIC igenzura uburebure bwa kaburimbo n'ibipimo byo gushyushya kugira ngo hirindwe koroha cyane mu gihe ihuye n'ibisabwa n'umukiriya.
(iminyururu ifite ubukana bwinshi bw'ubuso bwa karuboni)
(imiyoboro y'iminyururu ifite ubukana bwinshi bw'ubuso bwa karuboni, nyuma yo gupimwa imbaraga zo kumena)
Uburyo bwacu bwo gukora bugenzurwa neza kugira ngo tugere ku buringanire bwiza hagati y'ubukomere n'imbaraga. Binyuze mu gutunganya neza no kuvura ubushyuhe, twemeza koiminyururu n'iminyururuIfite ubuso bukomeye kandi budashobora kwangirika mu gihe ikomeza kugira igice gikomeye cyo hagati kugira ngo ishobore guhangana n'imizigo ihindagurika mu bikorwa byawe. Ubu buryo ni ingenzi cyane kugira ngo ibikoresho birambe neza kandi byizerwa.
III. Kugenzura igihe cy'ubuzima binyuze mu mikorere no kubungabunga
Ndetse no hamweiminyururu n'iminyururu by'ubuziranenge, gukoresha neza no kubungabunga ni ingenzi kugira ngo wongere igihe cyo kubaho mu nganda zitunganya amasasu. SCIC itanga ubuyobozi bukurikira ku bakiriya:
Amabwiriza agenga imicungire
1. Igenzura rihoraho:Igenzuraiminyururu n'iminyururuku bimenyetso byo kwangirika, nko kurekura (urugero, >2–3% by'uburebure bw'umwimerere), guhinduka kw'ibara, cyangwa kwangirika kw'ubuso. Kumenya hakiri kare birinda kwangirika.
2. Gusiga amavuta:Shyira amavuta ashyushye cyane kandi akomeye kugira ngo ugabanye kwangirika no kwangirika. Shyira amavuta buri masaha 100–200 y'akazi, bitewe n'imiterere.
3. Gukurikirana ihungabana:Komeza umugozi mwiza kugira ngo wirinde gucika intege cyane (bitera gutitira) cyangwa gufunga cyane (kongera kwangirika). Hindura ukurikije amabwiriza ya SCIC.
4. Gusimbuza ku gihe:Hitamo ibintu byashaje cyangwa byangiritse kugira ngo wirinde ko byangirika. Urugero, agatsiko kangiritse gakwiye gusimbuzwa vuba.
5. Uburyo bwiza bwo gukora:Koresha mu buryo bukurikije imipaka y'igishushanyo (urugero, irinde kurenza imbaraga za 280–300 N/mm²) kugira ngo ugabanye umuvuduko.
Kugira ngo iminyururu n'imishumi yawe birusheho kumara igihe kirekire, kurikiza ibi bikurikira: genzura buri gihe niba byasaze, reba neza ko amavuta akwiye akoreshwa, genzura imbaraga z'iminyururu, kandi usimbuze ibice byangiritse vuba. Ukurikije aya mabwiriza kandi ugakora mu buryo bujyanye n'imiterere, ushobora kongera uburyo bwo kwizerwa no gukora neza kwa ascenseur zawe.
Inyigo y'Urugero: Ingaruka ku Isi Nyayo
Ishusho:
Uruganda rwa sima rwahuye n’ibibazo byinshi byo kwangirika kw’imigozi y’uruziga, aho igihe cyo kuruhuka cyageraga ku masaha 10 buri kwezi bitewe n’imigozi ifite ubukana bwa 600 HV gusa n’ubujyakuzimu buto bwa kaburizi. Ibi byatumye ikiguzi cyo gusana gizamuka ndetse n’umusaruro ugabanuka.
Igisubizo:
Uruganda rwakoresheje imiyoboro ya SCIC ikora neza cyane:
- Ibipimo: umurambararo wa mm 30, ubukana bw'ubuso bwa mm 800, ubujyakuzimu bwa mm 3 bwo gukaraba, ubukana bufatika bwa mm 1.8 kuri mm 550 HV, imbaraga zo gucika za 290 N/mm².
- Kubungabunga: Igenzura rya buri cyumweru kabiri, amavuta akoreshwa buri masaha 150, no guhindura imbaraga.
(imiyoboro y'iminyururu ifite ubujyakuzimu bwa carburizing bwiza kugeza kuri 10% by'umurambararo w'imiyoboro)
IV. Ibisubizo
1. Igihe cyo kuruhuka: cyagabanutseho 80% (kugeza ku masaha 2 mu kwezi).
2. Igihe cy'ubuzima: Iminyururu yamaze amezi 18 (ugereranyije n'amezi 6 mbere).
3. Kuzigama Ikiguzi: Amafaranga yo kubungabunga yagabanutseho 50% buri mwaka.
Ibi bigaragaza uburyo ibice bya SCIC bifite ubuziranenge n'ubuyobozi bwo kubungabunga bitanga inyungu zifatika.
V. Umwanzuro
1. Guhitamo Ibice Bikwiye:Iminyururu n'iminyururu byemewe na SCIC bikurikiza DIN, ishyigikiwe n'igishushanyo mbonera cyiza no kugenzura ubuziranenge, igenzura umutekano n'imikorere myiza mu byuma bitunganya amabake by'uruganda rwa sima.
2. Kunganya Ubukomere n'Imbaraga: Uburyo bwacu bwo gukora bujyanye n'ibyo abakiriya basaba, butuma tudashira kandi bugatuma dushobora gutwara imizigo.
3. Gukoresha neza igihe cyose cy'ubuzima: Ubuyobozi bufatika bwo kubungabunga butuma habaho ubwizigirwa bw'igihe kirekire.
Binyuze mu bufatanye na SCIC, abakiriya babona iminyururu n'amapine byakozwe neza, bihuye n'ibyo bakeneye, kandi bigaterwa inkunga n'ingamba zifatika zo kunoza imikorere no kugabanya ikiguzi.
