Udizili ubanda ngaliphi izinga lokushisa ehlobo?
Okuqukethwe
Kuyini ukugcotshwa kwe-wax, futhi kungani kungalungile ngemoto kadizili?
Ama-wax edizili, ahlala etholakala kuphethiloli kadizili, angama-hydrocarbon amaketanga amade ajwayele ukucwebezela emazingeni okushisa aphansi. Lawa ma-platelet ayikristalu avimba izihlungi kumaketanga "we-wax" wangempela. Ama-hydrocarbon amaketango amade ahlanganisiwe andisa ngokuphawulekayo i-viscosity kaphethiloli we-diesel, okungalungile kokubili injini kanye nepompo likaphethiloli. Ukuba khona kwamanzi ngenani elikhulu ngokwanele kubangela enye inkinga - ukwakheka kwamakristalu eqhwa. Lokhu kwenzeka lapho kuqandisa khona uphethiloli we-diesel. Inkinga ukuthi: a) amanzi awancibiliki kunoma iyiphi i-hydrocarbon ewuketshezi; b) lawa makristalu emazingeni okushisa athile asevele eyinto eqinile, ngokungafani nopharafini, osewuketshezi.
Kuzo zombili izimo, uphethiloli wedizili uzoqala ukugeleza futhi kuphela uma ushisiswe ngaphezu kwezinga lokushisa lekristalu.
Inkinga, njengoba kwakubonakala, ingaxazululwa ngokungeza inani elithile (kusuka ku-7 kuya ku-10%) le-biodiesel kuphethiloli we-diesel. Kodwa-ke, okokuqala, uphethiloli we-biodiesel uyabiza, futhi okwesibili, lokhu ngezinye izikhathi kwakha into ewugqinsi ebangela ukugcwaliswa kwephethiloli ehlanzekile ye-diesel engenazo izithasiselo.
Ngokungafani nopharafini (lapho amakristalu ama-molecule ahlangene ehlukana nezinga lokushisa eliphakeme), ingxube kaphethiloli wedizili ne-biodiesel iba namafu futhi ayijahi ukubuyela kuphethiloli ojwayelekile.
Ukumiswa kwe-Turbid, okwenzeka ngesikhathi senqubo yokukhipha, kuvala izihlungi, ezithwala kakhulu ukusebenza kwepompo likaphethiloli. Ngenxa yalokho, izikhala ezingxenyeni ezihambayo ziyalahleka futhi izinqubo zokungqubuzana ezomile ziqala. Njengoba amazinga okushisa nezingcindezi ziphakeme, izinhlayiya zensimbi ezikhishwe ngokushesha ziphenduka zibe yimpushana yensimbi, eqala ukujiya bese kuba i-sinters. Futhi iphampu iphelile.
Ukuqinisekisa ukuthi lokhu akwenzeki, kuyadingeka ukusebenzisa izithasiselo ezifanele kuzingxube ze-biodiesel. Ngaphezu kwalokho, akufanele kube namanzi kuphethiloli we-diesel, okubuye kuvimbele izihlungi.
Ingabe ukhona umehluko phakathi "kwedizili yasebusika" kanye "nodizili wasebusika"?
Nakhu. Esimweni sokuqala, i-diesel fuel ixubene ne-parafini, esimweni sesibili, i-antigel yengezwa kuphethiloli we-diesel evamile. Amagalaji kaphethiloli amaningi ahlinzeka ngodizili wasebusika esikhundleni sikadizili wasebusika ngoba ushibhile. Abanye bahlakaniphe kakhudlwana futhi banikela ngazo zombili izinhlobo ukuvumela abathengi bazinqumele. Ezimotweni ezintsha, uphethiloli wedizili wasebusika oqukethe izithasiselo ezifanele uyathandwa.
Futhi kuthiwani nge-biodiesel? Ukuba khona kwayo kudinga ushintsho kubuchwepheshe bokucubungula uphethiloli, ngoba amaphuzu e-gelation ahluke komunye nomunye. Ngakho-ke, i-biodiesel izosabela ngendlela ehlukile ngezingxenye zesistimu kaphethiloli. I-Biodiesel, njengodizili, ama-gel esimweni sezulu esibandayo, kodwa izinga lokushisa eliqondile lokubunjwa kwejeli lizoncika ekutheni i-biodiesel yenziwe ngani. Amafutha edizili azophenduka abe ijeli cishe ezingeni lokushisa elifanayo lapho kuqala ukugcotshwa kwamafutha noma amafutha asetshenziswe ukwenza uphethiloli.
Iphuzu eliqandayo likadizili ehlobo
Kunzima ukubala ngokunembile lobu bubanzi ngoba kuningi okuguquguqukayo okusebenzayo. Nokho, amazinga okushisa amabili abalulekile ayaziwa:
- Iphuzu lefu yilapho i-wax kapharafini iqala ukuphuma kuphethiloli.
- Indawo yokuthela lapho udizili unejeli eningi kakhulu kangangokuthi ayisagelezi. Leli phuzu ngokuvamile lingaphansi kancane kwephoyinti lefu likaphethiloli.
Ngamafutha e-diesel ehlobo, izinga lokushisa lokuqala cishe lihambisana nobubanzi -4 ... -6ºC, kanti eyesibili -10 ... -12ºC (kucatshangwa ukuthi izinga lokushisa lomoya langaphandle elingashintshi). Ngokunemba kakhudlwana, lawa mazinga okushisa anqunywa kumalabhorethri, lapho kucatshangelwa khona ezinye izici zomzimba nemishini kaphethiloli.
