In sisitemu yo gutunganya sima, preheater nigice cyingenzi ninyubako yibikorwa byinganda zitanga sima.Irashobora gushyushya ifunguro mbisi no kunoza umusaruro witanura.Preheater flap valve igira uruhare runini mugukingira ikirere no guhora ugaburira bihoraho bikaba ihuza ryingenzi muri sisitemu ya preheater.Mubikorwa nyirizina, kubera igishushanyo mbonera kidafite ishingiro cya flap valve yateje umwuka mubi, guhindagurika no guhindagurika, bigira ingaruka zikomeye kumitekerereze yibyo kurya, ibisohoka mumatara azenguruka ndetse nubwiza bwa clinker bizagira ingaruka.
After Kugirango ukemure iki kibazo, nyuma yiperereza nubushakashatsi bwibigo byinshi, igisubizo cyo guhindura cyarateguwe kandi ibice byoroshye bifite amakosa birashobora gutezimbere imikorere ya flap valve ikora neza kandi ikagira ingaruka nziza yo gufunga.
a. Hindura amaboko ya shaft kumpande zombi kugirango umupira uhindurwe kugirango umenye neza imikorere, igikonoshwa gipfundikijwe hamwe na kashe yo gufunga kugirango ushireho igikonoshwa.
TUbwoko bwe bwububiko bufite imikorere myiza yo gufunga kandi birashobora gutuma isuku igira isuku, ibyo bikaba byerekana neza imikorere ya flap valve kandi bigahindura cyane ingaruka zo gufunga ikirere.
b. Igishushanyo cyigenga cyinjira kumuryango bituma igenzurwa ryigihe kizaza nogusimbuza plaque ya plaque byoroshye kandi byoroshye, bishobora kugabanya igihe cyo kubungabunga no kugabanya ikiguzi cyo kubungabunga.
After ihinduranya ya flap valve, guhagarara kwa clamping byavanyweho burundu, kandi plaque ya plaque yangiritse yarimo neza, bigera ku ngaruka zo kongera igihe cya serivisi no kugabanya ikiguzi cyibicuruzwa.
Tahindura neza ya preheater flap valve ntabwo azigama gusa kandi atanga inyungu zikomeye mubukungu, ahubwo anatanga inyungu zimwe mubijyanye no kuzigama ingufu, kugabanya ibicuruzwa, kunoza imikorere no kurengera ibidukikije.
