Mfundo Yozizirira Madzi ya Volvo Diesel Generator Set

Wopanga wa Volvo majenereta a dizilo aphunzira momwe njira zoziziritsira madzi zimagwirira ntchito: zoziziritsira madzi zitha kugawidwa m'makina oziziritsira madzi oyenda mokakamiza komanso njira zoziziritsira madzi zozungulira, kutengera momwe choziziritsira chimayendera.Jekete lamadzi ozizira limaponyedwa pamutu wa silinda ndi silinda ya injini ya dizilo.Pampu ikakanikizira choziziritsa, choziziritsira chimadutsa paipi yogawa kuti mukhazikitse jekete lamadzi la cylinder block.Madzi ozizira amatenga kutentha kuchokera pakhoma la silinda, amakwera kutentha, ndiyeno amalowa mu jekete lamadzi lamutu wa silinda ndi kulowa mupaipi yamadzi kudzera mu thermostat ndi radiator.Nthawi yomweyo, chifukwa cha kuyamwa kozungulira kwa fani, kulowa mu radiator, mpweya kudzera pa radiator pachimake kuwombedwa, kotero kutentha kumadutsa pakati pa radiator pachimake cha choziziritsa kukhosi kumatuluka nthawi zonse mumlengalenga, kutentha kumachepa.M'kupita kwa nthawi, popanikizidwa ndi mpope, imabwereranso mu jekete lamadzi la silinda, kotero kuti kuzungulira kumapitirira ndipo injini ya dizilo imathamanga kwambiri.Pofuna kuziziritsa bwino ma silinda akutsogolo ndi akumbuyo a injini za dizilo zamitundu yambiri, injini za dizilo nthawi zambiri zimakhala ndi mapaipi ogawa madzi kapena kuponya zipinda zogawa madzi mu silinda.Chitoliro chogawa ndi chitoliro chachitsulo chomwe chimatulutsa kutentha kwa mafuta pamtunda wa dzenje la madzi.Pampu yokulirapo, kuyandikira kwamphamvu kwa kuziziritsa kwa masilindala akutsogolo ndi kumbuyo, makina onsewo amakhala atakhazikika.

Zambiri za Volvo jenereta dizilo gwiritsani ntchito njira yoziziritsira madzi mokakamiza.Ndiko kuti, mpope wamadzi umagwiritsidwa ntchito kuonjezera kuthamanga kwa sing'anga yozizira.Kuchuluka kwa dongosolo lozizira kumakhala kochepa kwambiri kusiyana ndi kayendedwe ka chilengedwe, ndipo kuziziritsa kwazitsulo zam'mwamba ndi zam'munsi kumakhala kofanana.

Dongosolo loziziritsa madzi lilinso ndi sensa ya kutentha kwa madzi ndi mita ya kutentha kwa madzi.Sensa ya kutentha kwa madzi imayikidwa pa chitoliro chotulutsira chamutu wa silinda, ndipo kutentha kwa madzi kuchokera ku chitoliro cha mtsinje kumapititsidwa ku mita ya kutentha kwa madzi.Wogwiritsa ntchito nthawi zonse amatha kugwiritsa ntchito mita ya kutentha kwa madzi kuti awone momwe makina ozizirira amagwirira ntchito.Kutentha kwamadzi ogwirira ntchito nthawi zambiri kumakhala 80-90 ° C.Kukana kozizira komanso kozizira usiku.Chozizirira chomwe chimagwiritsidwa ntchito mu injini za dizilo chiyenera kukhala madzi ofewa aukhondo.Ngati madzi olimba agwiritsidwa ntchito, mchere womwe uli mmenemo udzakhazikika pa kutentha kwakukulu ndi kumamatira ku mapaipi, ma jekete ndi ma radiator kuti apange sikelo ndi kuchepetsa kutentha kwa kutentha.Kutha kutenthetsa mosavuta injini ya dizilo kumatha kuwononganso pakatikati pa radiator ndikufulumizitsa kuvala kwa chopondera chapope ndi casing.Madzi olimba omwe ali ndi mchere wambiri amafunika kufewetsa asanayambe kuwonjezeredwa ku makina ozizirira.Njira yodziwika bwino yochepetsera madzi olimba ndikuwonjezera 0.5-1.5g ya sodium carbonate ku 1L yamadzi.Ngati chinthucho chikukwera, zonyansa zopangidwa mu 0.5-0.8g ya sodium hydroxide zimatenthedwa, ndipo madzi oyeretsedwa amabayidwa mu ozizira.
