Sefa yamchenga, yomwe imadziwikanso kuti quartz sand filter, mchenga fyuluta, ndi fyuluta yomwe imagwiritsa ntchito mchenga wa quartz homogeneous ndi wofanana ndi tinthu tating'onoting'ono tomwe timapanga mchenga wa mchenga ngati chonyamulira chonyamulira cha kusefera kwamitundu itatu.Nthawi zambiri amagwiritsidwa ntchito kusefera koyambirira.Imagwiritsa ntchito mchenga ndi miyala ngati zosefera.
Sefa yamchenga ndi miyala ndi imodzi mwazosefera zapa media.Bedi lake lamchenga ndi fyuluta yamitundu itatu ndipo limatha kutsekereza dothi.Ndi oyenera kusefera madzi bwino bwino, mankhwala ulimi madzi, ndi chisanadze mankhwala a njira zosiyanasiyana madzi mankhwala, etc. Malo osiyanasiyana monga mafakitale, kumidzi, mahotela, masukulu, minda munda, zomera madzi, etc. Pakati zosefera onse , fyuluta yamchenga ndiyo njira yabwino kwambiri yochitira zonyansa za organic ndi organic m'madzi.Fyulutayi imatha kusefa ndikusunga zonyansa ndipo imatha kupereka madzi osasokoneza.Malingana ngati organic zili m'madzi kuposa 10mg/L, ziribe kanthu kuchuluka kwa inorganic content, mchenga fyuluta ayenera kugwiritsidwa ntchito.
mfundo ntchito:
Pa ntchito bwinobwino, madzi osefa kufika sing'anga wosanjikiza kudzera madzi polowera.Panthawiyi, zowonongeka zambiri zimagwidwa pamwamba pa sing'anga, ndipo dothi labwino ndi zinthu zina zoyandama zomwe zimayandama zimatsekeredwa mkati mwapakati kuti zitsimikizire kuti dongosolo lopanga zisakhudzidwe ndi Kusokonezedwa kwa zowononga zimatha kugwira ntchito bwino.Pambuyo pa opaleshoni, pamene zonyansa ndi zolimba zosiyanasiyana zoyimitsidwa m'madzi zimafika pamlingo wina, makina a fyuluta amatha kuzindikira kusiyana kwa kuthamanga pakati pa malo olowera ndi kutuluka mu nthawi yeniyeni kupyolera mu chipangizo chowongolera kusiyana.Pamene kusiyana kwapakati kufika pamtengo wokhazikitsidwa, PLC yolamulira zamagetsi idzapereka njira yoyendetsera njira zitatu za hydraulic control valve zimatumiza chizindikiro.Njira zitatu zoyendetsera ma hydraulic control valve zidzangoyendetsa valavu ya njira zitatu zofananira zosefera kudzera mumsewu wamadzi, kulola kutseka njira yolowera ndikutsegula njira yachimbudzi nthawi yomweyo.Madzi a unit adzalowa kudzera m'madzi a fyuluta unit pansi pa mphamvu ya madzi, ndikupitiriza kutsuka sing'anga wosanjikiza wa unit fyuluta, kuti akwaniritse zotsatira kuyeretsa sing'anga.Zonyansa zotsuka zidzasefedwa ndi kuthamanga kwa madzi.Chimbudzi cha unit chimalowa mu chitoliro cham'madzi kuti chitsirizitse ntchito yochotsa madzi ofunda.Fyuluta yamchenga ya AIGER imathanso kugwiritsa ntchito nthawi kuti ichotse zimbudzi.Nthawi ikafika nthawi yokhazikitsidwa ndi woyang'anira nthawi, bokosi loyendetsa magetsi lidzatumiza chizindikiro chotsuka zonyansa ku valavu yoyendetsera ma hydraulic control valve.Njira yeniyeni yachimbudzi ndi monga pamwambapa.
