Umqoqi wesihlungi - ukufaka epanini likawoyela elingaphambili lephampu kawoyela.
Ngenxa ye-viscosity enkulu kawoyela ngokwawo kanye nokuqukethwe okuphezulu kwemfucumfucu emafutheni, ukuze kuthuthukiswe ukusebenza kahle kokuhlunga, isihlungi sikawoyela ngokuvamile sinamazinga amathathu, okuyisihlungi sokuqoqa uwoyela, isihlungi sawoyela esimahhadla kanye nenhlawulo kawoyela. isihlungi. Isihlungi sifakwa epanini likawoyela phambi kwephampu kawoyela, futhi ngokuvamile samukela uhlobo lwesikrini sesihlungi sensimbi.
Ukuze kuncishiswe ukumelana nokungqubuzana phakathi kwezingxenye ezihambayo ezihambayo enjinini futhi kuncishiswe ukuguga kwezingxenye, uwoyela uhanjiswa njalo endaweni yokungqubuzana kwezingxenye ezihambayo ukuze enze ifilimu yamafutha okugcoba ukuze kugcotshwe. Amafutha ngokwawo aqukethe inani elithile le-gum, ukungcola, umswakama kanye nezithasiselo. Ngesikhathi esifanayo, ngesikhathi sokusebenza kwenjini, ukwethulwa kwezinsalela zensimbi, ukungena kwemfucumfucu emoyeni, nokukhiqizwa kwama-oksidi kawoyela kwenza imfucumfucu emafutheni yande kancane kancane. Uma uwoyela ungahlungiwe futhi ungena ngqo emgwaqeni kawoyela wokugcoba, uzoletha imfucumfucu equkethwe emafutheni endaweni yokungqubuzana kombhangqwana onyakazayo, isheshise ukuguga kwezingxenye futhi inciphise impilo yesevisi yenjini. Umsebenzi wesihlungi samafutha ukuhlunga udoti, inhlaka namanzi emafutheni, nokuletha amafutha ahlanzekile ezingxenyeni zokugcoba.
Isihlungi se-oyili esimahhadla sifakwe ngemuva kwephampu kawoyela, kanti isiteshi sikawoyela esiyinhloko ochungechungeni, ikakhulukazi uhlobo lwe-scraper yensimbi, uhlobo lwesihlungi se-sawdust core, uhlobo lwephepha lokuhlunga le-microporous, ikakhulukazi lisebenzisa uhlobo lwephepha lokuhlunga le-microporous. Isihlungi esihle sikawoyela sifakwe ngokuhambisana nephaseji likawoyela eliyinhloko ngemva kwephampu kawoyela. Kukhona ikakhulukazi izinhlobo ezimbili zohlobo lwephepha lokuhlunga le-microporous kanye nohlobo lwe-rotor. Isihlungi sikawoyela we-rotor samukela ukuhlunga kwe-centrifugal ngaphandle kwesici sokuhlunga, esixazulula ngempumelelo ukungqubuzana phakathi kokungena kwamafutha nokusebenza kahle kokuhlunga.
Izinhlobo zokulimala kwesihlungi sikawoyela ikakhulukazi zimi kanje:
1, isihlungi simbozwe ngamafutha, noma isihlungi sonakalisiwe.
2, i-buoy iyancibilika noma iqhume, amafutha ku-buoy noma isihlungi setha isikali esiningi kakhulu nokuvinjelwa okubangelwa umonakalo.
3, ipayipi ivinjiwe; Idivayisi yonyawo olubambayo ayinamandla futhi iyawa ngemva kokudlidliza, okubangela ukulimala ku-accumulator.
Isihlungi sikawoyela sifakwe phambi kwendawo yokungena kawoyela yephampu kawoyela, futhi umsebenzi wayo oyinhloko ukuvimbela ukungcola okukhulu kwemishini ukuthi kungangeni empompini yamafutha yomshini womuntu. Ifomu lokuqoqa isihlungi lingahlukaniswa libe isihlungi esintantayo nesihlungi esingashintshi.
Ihlunga ngomqoqi wokuhlunga
1. Setha isihlungi
Umqoqi wokuhlunga ngokuvamile uklanywa ngesikrini sokuhlunga futhi utholakala ngaphambi kwepompo likawoyela ukuvimbela izinhlayiya ezinkulu ukuthi zingangeni empompini yamafutha. Isihlungi somqoqi sihlukaniswe ngezinhlobo ezimbili ezintantayo futhi ezilungisiwe.
Isihlungi esintantayo singamunca uwoyela ohlanzekile ongqimbeni olungaphezulu, kodwa kulula ukuhogela igwebu, okuholela ekwehleni komfutho kawoyela kanye nomphumela wokugcoba ongazinzile. Isihlungi esinqunyiwe sitholakala ngaphansi kwezinga likawoyela, nakuba ukuhlanzeka kwamafutha aphefumulelwe kubi kakhulu kunohlobo oluntantayo, kodwa kugwema ukudonsa kwegwebu, umphumela wokugcoba uzinzile, isakhiwo silula, futhi injini yamanje yezimoto isebenzisa isihlungi esinjalo.
Okwesibili, isihlungi sikawoyela esigcwele
Isihlungi sikawoyela esigcwele ngokugcwele sixhunywe ochungechungeni phakathi kwephampu kawoyela kanye nephaseji eliyinhloko likawoyela ukuze lihlunge wonke uwoyela. Njengamanje, izinjini eziningi zezimoto zisebenzisa izihlungi zikawoyela ezigcwele.
Izihlungi zikawoyela ezigcwele ngokugcwele zinemiklamo ehlukahlukene yokuhlunga, okuyizihlungi zephepha ezivame kakhulu. Izihlungi zamafutha ezinezici zokuhlunga iphepha zihlukaniswe zibe izinhlobo ezimbili: ezibolayo nezibalulekile. Lapho isici sokuhlunga sivinjelwa kakhulu ukungcola, ingcindezi kawoyela endaweni yokungena kawoyela yesihlungi izokhuphuka, futhi lapho ifinyelela inani elithile, i-valve ye-bypass izovulwa, futhi uwoyela uzongena ngqo emgudwini omkhulu kawoyela ngaphandle kokuhlunga. ngokusebenzisa isici sokuhlunga. Nakuba amafutha ethuthwa ezingxenyeni ezihlukahlukene zokugcoba ngaphandle kokuhlunga ngalesi sikhathi, kungcono kakhulu kunokuntuleka kwamafutha okugcoba.
Okwesithathu, isihlungi sikawoyela sohlobo oluhlukanisiwe
Amaloli amakhulu, ikakhulukazi izinjini zamaloli asindayo, ngokuvamile asebenzisa inhlanganisela yezihlungi zikawoyela ezigcwele ngokugcwele kanye ne-shunt. Isihlungi esigcwele ngokugcwele sinesibopho sokuhlunga ukungcola ngezinhlayiya ezingaphezu kuka-0.05mm emafutheni, kuyilapho isihlungi se-shunt sinesibopho sokuhlunga ukungcola okuncane ngezinhlayiya ezingaphansi kuka-0.001mm, futhi kuphela u-5% kuya ku-10% wokunikezwa kukawoyela iphampu yamafutha iyahlungwa.
Isihlungi esihle sohlobo lwe-shunt sinezinhlobo ezimbili: uhlobo lwesihlungi nohlobo lwe-centrifugal. Njengamanje, isihlungi sikawoyela we-centrifugal sisetshenziswa kakhulu. Ine-rotor ngaphakathi esekelwe ku-shaft ngama-bearings. Kukhona ama-nozzles amabili ku-rotor, esebenzisa ingcindezi yokusebenza yesistimu yokugcoba ngokwayo, lapho uwoyela engena ku-rotor futhi ephuma ku-nozzle, i-torque ye-recoil ikhiqizwa, okwenza i-rotor ijikeleze ngesivinini esikhulu. Ngaphansi kwesenzo samandla we-centrifugal, ukungcola okuqinile emafutheni kuyahlukaniswa futhi kuqoqwe odongeni lwangaphakathi lwe-rotor. Amafutha aphakathi nendawo ye-rotor ahlanzekile futhi ageleza esuka emlonyeni abuyele epanini likawoyela.
Okwesine, isihlungi sikawoyela we-centrifugal
Isihlungi sikawoyela we-Centrifugal sibonakala ngokusebenza okuzinzile, isakhiwo esithembekile, asikho isidingo sokushintsha isici sokuhlunga. Vele ususe i-rotor njalo futhi uhlanze ibala ebusweni be-rotor, ungayisebenzisa futhi, futhi impilo yesevisi yinde. Kodwa-ke, isakhiwo sayo siyinkimbinkimbi, intengo iphakeme, isisindo sikhulu, futhi izidingo zobuchwepheshe zabasebenzi bezokunakekelwa ziphakeme.
