Tisanadumphire m'magawo ogwirira ntchito, tiyeni tiyambe kumvetsetsa cholinga ndi zigawo za ma valve a ma port ambiri.Valavu yamitundu yambiri ndi gawo lofunikira la fyuluta ya mchenga, yomwe imayang'anira kuwongolera madzi kudzera muzosefera zosiyanasiyana.Nthawi zambiri imakhala pamwamba pa canister ndipo imagwiritsidwa ntchito poyang'anira ntchito monga kusefera, kusambitsa kumbuyo, kutsuka, kuwononga ndi kubwezeretsanso.Valavu imakhala ndi maudindo osiyanasiyana kuphatikizapo fyuluta, backwash, flush, zinyalala ndi recirculate, aliyense amene ali ndi cholinga choyeretsa.
 
Chitsogozo chatsatane-tsatane pogwiritsira ntchito valavu yamadoko ambiri:
1. Sankhani malo oyenera: Yambani ndikuzindikira malo oyenera omwe mukufuna pa ntchito yanu yokonza dziwe.Kuti musefe nthawi ndi nthawi, ikani valavu pamalo osefera.
2. Backwashing: Pamene choyezera kuthamanga pa fyuluta kufika pa mlingo wapamwamba, backwashing ikuchitika.Ingozimitsani mpope, kukankhira valavu pansi ndikuitembenuzira kumalo osungira kumbuyo, ndikuyatsanso mpope.Lolani madzi kuti aziyenda mobwerera kumbuyo kuti achotse zinyalala pakama lamchenga.
3. Flush: Mukabwerera mmbuyo, ikani valve kuti "isungunuke" ndikuyendetsa mpope kwa nthawi yochepa.Izi zimathandiza kuthetsa bedi lamchenga ndikuchotsa zinyalala zomwe zatsala panjira yotsukira msana.
4. Madzi onyansa: Kuti muchepetse mlingo wa madzi mu dziwe, ikani valavu pamalo amadzi onyansa.Izi zimalambalala bwino fyulutayo ndikulola madzi kukhetsa mwachindunji.
5. Kubwezeretsanso: Gwiritsani ntchito malo obwezeretsanso ngati mukufuna kudutsa fyuluta koma sungani madzi mkati mwa dziwe.Izi ndizothandiza kwambiri pamene mukuwonjezera mankhwala omwe amatha kutseka fyuluta.
6. Kusamalira nthawi zonse: Ndikofunikira kwambiri kukonza zosefera pa thanki yamchenga tsiku ndi tsiku, kuphatikizira kuyeretsa thanki yamadzi ndikusintha mchenga pazaka 5-7 zilizonse.Onetsetsani kuti mukutsatira malangizo a wopanga kuti mukhale otetezeka komanso ogwira mtima.
 
Kugwiritsa ntchito valavu yamitundu yambiri pa fyuluta ya dziwe la mchenga sikuyenera kukhala kowopsa.Podziwa malo osiyanasiyana ndikutsatira ndondomeko ya sitepe ndi sitepe, mutha kukhalabe ndi zochitika zapamwamba komanso kusunga dziwe lanu loyera nthawi yonse yosambira.Kumbukirani kuika patsogolo kukonza nthawi zonse chifukwa izi zidzakulitsa moyo wa makina anu a mchenga.Tsopano, pokhala ndi chidziwitso chogwiritsa ntchito ma valve ambiri, mutha kukwaniritsa molimba mtima kusefera kwa dziwe ndikusangalala ndi kusambira kotsitsimula mu dziwe lanu losamalidwa bwino.
