Mafuta fyuluta m'nyengo yozizira
Kutsekeka kwamafuta ndikosowa. Komabe, kusefera kwamafuta ndikofunikira kwambiri, makamaka mu injini za dizilo.
Magawo amafuta masiku ano savutika ndi kuipitsidwa kwamafuta. Ma injini amakono okhala ndi jekeseni wamafuta amakhala ndi zosefera zabwino kwambiri komanso zolondola zamafuta, motero salephera chifukwa cha izi.
Mapangidwe olondola a jekeseni amafunikira mafuta oyera - ndipo mafuta otere amaperekedwa, ndipo zonyansa zilizonse zimayikidwa mu fyuluta. Popeza kuti chipangizochi nthawi zambiri chimabisika mozama, n’chosavuta kuchiiwaliratu. Kodi ndi koyenera kuwasintha ngati injini ikugwirabe ntchito mosalakwitsa? Komabe, ndizoyenera (kamodzi pazaka ziwiri zilizonse), chifukwa sitidziwa kwenikweni kuchuluka kwa dothi komwe kwachuluka mu fyuluta komanso ngati kumapangitsa kukana kwambiri kutuluka kwa mafuta.
Pampu yokakamiza idzathana ndi izi, koma kwa kanthawi. M'malo mwake, fyuluta yamafuta mu injini zamafuta iyenera kusinthidwa kutengera mtunda wagalimoto komanso kuyera kwamafuta. Gawo lomaliza silingathe kulamulira, choncho tiyeni tivomereze kuti nthawi zina tidzasintha fyuluta, yomwe inali yoyera mokwanira.
Zinthu ndizosiyana kwambiri ndi injini za dizilo. Amafunikanso mafuta oyera kwambiri, koma kuwonjezera apo, mafuta a dizilo amatha kugwa ndipo amawonjezera kukhuthala kwake ndi kutentha pang'ono, ndipo pansi pamtengo wina, parafini imatulutsidwa. Izi zimachitika mu thanki yamafuta ndi muzosefera zamafuta.
Chifukwa chake, zosefera dizilo ndi mtundu wa sump momwe madzi ndi tizigawo tamafuta olemera ayenera kusonkhanitsidwa. M'chilimwe, izi nthawi zambiri zimakhala zopanda ntchito, koma m'nyengo yozizira ndi yozizira m'pofunika kumasula ndi kuyeretsa nthawi zonse makilomita zikwi zingapo. Njirayi nthawi zambiri imakhala ndi kumasula decanter ndi kukhetsa zinyalala. Tiyenera kukumbukira kuyeretsa chipangizochi, makamaka tisanayambe ulendo wautali, monga nthawi ya tchuthi chachisanu.
Njira yabwino koposa ndiyo kusinthira fyuluta yamafuta ndi yatsopano chaka chilichonse nyengo yachisanu isanakwane. Zowona, panthawiyi timagwiritsa ntchito nyengo yozizira (i.e., parafini-precipitating pa kutentha kochepa) mafuta a dizilo, depressants (mafuta owonjezera omwe amasungunula parafini) akhoza kuwonjezeredwa, koma ngakhale kuukira kumodzi kwa chisanu kukhoza kusokoneza moyo wathu.
