Isici sokuhlunga uwoyela wenjini isihlungi sikawoyela wenjini. Umsebenzi wesihlungi sikawoyela wenjini ukuhlunga ama-sundries, ama-colloid kanye nomswakama kuwoyela wenjini nokuletha amafutha enjini ahlanzekile kuzo zonke izingxenye zokugcoba.
Ukuze kuncishiswe ukumelana nokungqubuzana phakathi kwezingxenye ezihambayo enjinini futhi kuncishiswe ukuguga kwezingxenye, uwoyela uhanjiswa ngokuqhubekayo endaweni engqubuzanayo yengxenye ngayinye ehambayo ukuze kwakheke ifilimu kawoyela wokugcoba ukuze kugcotshwe. Amafutha enjini ngokwawo aqukethe inani elithile le-gum, ukungcola, umswakama kanye nezithasiselo. Ngesikhathi esifanayo, ngesikhathi sokusebenza kwenjini, ukwethulwa kwemfucumfucu yensimbi yokugqoka, ukungena kwama-sundries emoyeni kanye nokukhiqizwa kwama-oxides kawoyela kancane kancane kwandisa ama-sundries emafutheni. Uma uwoyela ungahlungiwe futhi ungena ngokuqondile kumjikelezo kawoyela wokugcoba, ama-sundries aqukethwe emafutheni azolethwa endaweni yokungqubuzana kombhangqwana onyakazayo, asheshise ukuguga kwezingxenye futhi anciphise impilo yesevisi yenjini.
Ngenxa ye-viscosity ephezulu kawoyela wenjini uqobo kanye nokuqukethwe okuphezulu kokungcola kuwoyela wenjini, ukuze kuthuthukiswe ukusebenza kahle kokuhlunga, isihlungi sikawoyela wenjini ngokuvamile sinamazinga amathathu: umqoqi kawoyela wenjini, isihlungi samafutha enjini kanye nowoyela wenjini yesibili. isihlungi. Umqoqi wokuhlunga ufakwa epanini likawoyela phambi kwepompo likawoyela futhi ngokuvamile wamukela uhlobo lwesikrini sesihlungi sensimbi. Isihlungi sikawoyela esiyinhloko sifakwa ngemuva kwephampu kawoyela futhi sixhunywe ngochungechunge nephaseji eliyinhloko likawoyela. Ihlanganisa ikakhulukazi i-metal scraper, i-sawdust filter element kanye nephepha lokuhlunga le-microporous. Manje i-microporous filter paper isetshenziswa kakhulu. Isihlungi esihle sikawoyela sifakwe ngemuva kwephampu kawoyela futhi sixhunywe ngokuhambisana nephaseji likawoyela eliyinhloko, ikakhulukazi okuhlanganisa uhlobo lwephepha lokuhlunga le-microporous kanye nohlobo lwe-rotor. Isihlungi se-oyela sohlobo lwe-rotor samukela ukuhlungwa kwe-centrifugal ngaphandle kwesici sokuhlunga, okuxazulula ngempumelelo ukungqubuzana phakathi kokuthuthwa kukawoyela nokusebenza kahle kokuhlunga.
