Incazelo yokuminyana kukadizili nokubaluleka kwayo
Ukuminyana kukadizili kuyipharamitha ebalulekile yokukala ikhwalithi nokusebenza kukaphethiloli wedizili. Ukuminyana kubhekisela kumthamo weyunithi ngayinye kaphethiloli wedizili futhi kuvame ukuvezwa ngamakhilogremu ku-cubic meter ngayinye (kg/m³). Ezimbonini zamakhemikhali namandla, ukuminyana kukadizili kunomthelela oqondile ezicini eziningi zokusebenza kukaphethiloli, ukugcinwa kanye nezokuthutha.
Ibanga elijwayelekile lokuminyana kukadizili
Empeleni, ukuminyana kukaphethiloli we-diesel kuvamise ukuba ku-800 kuya ku-900 kg/m³, kodwa lobu bubanzi bungase buhluke kuye ngenqubo yokukhiqiza, umthombo wempahla eluhlaza kanye nokwakheka kwezithasiselo. Isibonelo, ukuminyana kukaphethiloli wedizili ojwayelekile (No. 0 uphethiloli wedizili) kuvame ukuba ngu-835 kg/m³, kuyilapho ukuminyana kwamanye amafutha edizili acutshungulwe ngokukhethekile kungase kuhluke kancane. Ngakho-ke, lapho ukhetha uphethiloli wedizili, ukwazi uhla lokuminyana kwawo kungasiza ukwahlulela ikhwalithi nokufaneleka kwawo.
Umthelela wokuminyana kukadizili ekusebenzeni kokuvutha
Ukuminyana kukadizili kunomthelela omkhulu ekusebenzeni kahle komlilo. Ngokuvamile, uphethiloli wedizili onokuminyana okuphezulu ukhipha amandla engeziwe ngesikhathi sokusha ngoba uqukethe ama-hydrocarbon amaningi ngevolumu yeyunithi ngayinye. Ukuminyana okwedlulele kungase kuholele ekuncipheni kwekhwalithi yesifutho yama-injection, ngaleyo ndlela kuthinte ukusebenza kahle kokuvutha kanye namazinga okukhipha umoya. Ngakho-ke, ukuminyana kukadizili kudinga ukulawulwa ngokunembile kukho kokubili ukukhethwa kukaphethiloli kanye nokwakhiwa kwenjini ukuze kuqinisekiswe ukushiswa okukahle kanye nokukhipha ukungcola okuncane.
Umthelela wezinga lokushisa elizungezile ekumineni kukadizili
Ukuminyana kukaphethiloli we-diesel kuyashintsha nezinga lokushisa. Ngokuvamile, ukuminyana kukaphethiloli we-diesel kuncipha kancane njengoba izinga lokushisa likhuphuka. Lokhu kungenxa yomphumela oshisayo wokwandisa ama-molecule edizili emazingeni okushisa aphezulu. Ngokusebenza, umphumela wokushisa ku-density yamafutha e-diesel udinga ukucatshangelwa ngokucophelela, ikakhulukazi ngesikhathi sokugcinwa nokuthutha uphethiloli we-diesel, lapho ukulawulwa kwezinga lokushisa okungalungile kungase kubangele amaphutha e-volumetric. Ngenxa yalesi sizathu, izinkampani zikawoyela ngokuvamile zilungisa ukuminyana kukaphethiloli wedizili ukuze izinga lokushisa liqiniseke ukuze kuqinisekiswe ukunemba ezindaweni ezihlukene.
Indlela Yokukala Ukuminyana Kwedizili
Ukulinganisa ukuminyana kukadizili kuvame ukwenziwa kusetshenziswa i-densitometer noma ibhodlela elithile lamandla adonsela phansi. Umsebenzisi uzoqale athele isampula likadizili emshinini wokulinganisa futhi aqinisekise ukuthi izinga lokushisa lesampula lizinzile. Inani lokuminyana likaphethiloli wedizili lingase lithathwe ekufundweni kwe-densitometer noma ifomula yebhodlela elithile lamandla adonsela phansi. Le nqubo, nakuba ibonakala ilula, idinga izinga elithile lobuchwepheshe engxenyeni yesisebenzisi ukuze kuqinisekiswe ukunemba nokwethembeka kwesilinganiso.
Ubudlelwano phakathi kokuminyana kukadizili nezindawo zokufaka isicelo
Izimo zokufaka ezihlukene zinezidingo ezihlukene zokuminyana kukadizili. Isibonelo, uphethiloli wedizili wezinga lokushisa eliphansi osetshenziswa ezindaweni ezibandayo uzolungiswa ukuminyana kwawo uma kuqhathaniswa nophethiloli ojwayelekile wedizili ukuze kuvinjelwe ukuqina ngaphansi kwezimo ezisezingeni eliphansi. Ngakolunye uhlangothi, uphethiloli wedizili osetshenziswa ezinjinini ezisebenza kahle zidinga ibhalansi phakathi kokuminyana nokusebenza kahle komlilo ukuze kuqinisekiswe ukuphuma kwamandla nokonga kukaphethiloli. Ngakho-ke, ukuqonda ukuminyana kukaphethiloli wedizili nokukhetha ngokwezidingo zohlelo lokusebenza kuyisihluthulelo sokuqinisekisa ukusebenza kahle nokwelula impilo yesevisi yemishini.
Isiphetho
Ukuminyana kukadizili kungenye yezinkomba ezibaluleke kakhulu zekhwalithi nokusebenza kukadizili. Ngokuqonda ububanzi obujwayelekile, izici ezithonya kanye nezindlela zokulinganisa zokuminyana kukadizili, ungakhetha kangcono imikhiqizo kadizili efanele izimo zohlelo lokusebenza ezihlukene. Lokhu akusizi nje ukuthuthukisa ukusebenza kahle kukaphethiloli, kodwa futhi kunciphisa ukungcola nokuvikela imvelo. Ukuminyana kukadizili kuzoqhubeka nokubamba iqhaza elibalulekile ekufakweni kwezicelo zikadizili nocwaningo lwangomuso.
