Ngokuthuthuka okusheshayo kwezolimo nezimboni

I-slurry entantayo indandatho uphawu

Ngokuthuthuka okusheshayo kwezolimo kanye nezimboni, amaphampu okucindezela aphezulu kakhulu nangaphezulu, ukucindezela kokungena kwepompo kufika ku-100 kg / cm ^ 2, noma 200 kg / cm ^ 2, izinga lokushisa eliwuketshezi lifika ku-200-400C. Kulesi simo kukhona uphawu oluthile lwemishini olunzima, futhi uphawu lwendandatho entantayo lufaneleka kakhulu. Isakhiwo sophawu lwendandatho entantayo silula ( uma siqhathaniswa nesigxivizo esiwumshini). Vula ama-mesons amaningi phakathi kwezimpawu zemishini nokupakisha. Ukusebenza okuthembekile, kodwa kukhudlwana kunobukhulu be-axial benye indlela yokuvala . Isici esintantayo sendandatho siwukusebenzisa ukuthintana nobuso bendandatho entantayo kanye namayunithi antantayo ukuze kuzuzwe izimpawu zobuso bokuphela kwe-axial, i-radial shaft seal iyindawo eyi-cylindrical ngendawo eyindandatho entantayo yendingilizi engaphakathi ye-slit ewumngcingo ukuze kukhiqizwe i-throttling evalekile.

Uma kuqhathaniswa nezinye izinhlobo zezimvu zamanzi, indandatho entantayo enezinzuzo zokuziqondanisa. Ngenxa yokuthi ziyakwazi ukuziqondanisa, ukucaciswa kwe-radial kungenziwa kuncane kakhulu. Indandatho entantayo kanye negebe phakathi komkhono nobude begebe kuyisici esibalulekile esithinta inani lokuvuza .

Umfanekiso 9-13 entwasahlobo izindandatho ezintathu ezintantayo zidlala indima yokusekela. I-Floating ring seal ingaklanywa njengendandatho eyodwa, ingasetshenziswa futhi emasongweni amaningana axhumene nomunye nomunye, enziwe ngophawu olude. Ngaphansi kwezimo ezivamile , kufanele ibe ngaphandle kwezimbobo zokukhulula indandatho entantayo exhunywe endaweni yokucindezela okuphansi , ukuze idlale umphumela wokuphehla kwegebe lokuvala , kodwa ingakwazi ukuvimba imbobo yokukhulula . Kwethulwe ngaphezu kohlobo lwe-centrifugal lwe-seal oluvame ukusetshenziswa kakhulu,umkhiqizi wepompo ye-slurryngokuthuthukiswa kwesayensi nezobuchwepheshe, ubuchwepheshe be-seal ngokwayo buyashintsha, izigxivizo zenjoloba, ukupakisha, izimpawu zemishini, indandatho entantayo ngokwayo isathuthukiswa futhi ithuthukiswe, futhi kungenzeka ngokuphelele ukuvela kwesakhiwo sophawu olusha, kusemkhuba kuphela. wokushintsha iqiniso ukuze uqhubeke nokuthola nokubamba umthetho wemvelo wezinto zangaphandle , ukukhuthaza ukuthuthukiswa kwezinto .

Ama-centrifugal rotor bearings anezingxenye, imithwalo ye-radial ne-axial. Ngokusho kwesakhiwo esithwalayo singahlukaniswa ngezigaba ezimbili ezigoqayo nezishelelayo.
