Uwoyela ontantayo uphawu yigama elivamile lezimvu zamanzi ezintantayo, eziyingxenye yophawu lwemishini ezimpawini eziguquguqukayo.Isebenza kahle kakhulu ngokuvala ezindaweni zokusebenza ezinokhahlo njengempushana yamalahle, inzika, nomhwamuko wamanzi.Kuyi-compact mechanical seal ikakhulukazi esetshenziswa ngesivinini esiphansi kanye nezimo zomthwalo osindayo.Inezinzuzo zokumelana nokugqoka, isinxephezelo esizenzakalelayo ngemuva kokugqoka kobuso bokuphela, ukusebenza okuthembekile, kanye nesakhiwo esilula, futhi isetshenziswa kabanzi emishinini yezimayini zamalahle.Njengomshini wokuhamba ngogandaganda, izingxenye ze-sprocket zekhanda le-scraper conveyor (umsila), indlela yokulayisha isihloko somgwaqo kanye nesigaba se-cantilever, izigubhu zokusika kwesokunxele nakwesokudla kanye nezinciphisi zemishini yezimayini yamalahle eqhubekayo, njll.
Okuntantayouwoyela uphawuisetshenziswa kusinciphisi seplanethi sengxenye ehambayo yemishini yokwakha ukuze sivale ngokuguquguqukayo ubuso bokuphela bengxenye.Ngenxa yokuthembeka kwayo okuphezulu, iphinda isetshenziswe njengophawu oluguqukayo lwe-shaft ephumayo yesondo lebhakede le-dredger.Lolu hlobo lophawu olwezimpawu zemishini futhi ngokuvamile luhlanganisa indandatho entantayo eyenziwe ngezinto ze-ferroalloy kanye ne-nitrile rubber O-ring seal efanayo.Izindandatho ezintantayo zisetshenziswa ngababili, enye izungeza nengxenye ejikelezayo kanti enye imile, ehluke kakhulu kuneringi yophawu lukawoyela.
Isigxivizo sikawoyela esintantayo sakhiwe izindandatho ezimbili ezifanayo zensimbi nezindandatho ezimbili zenjoloba.Isimiso sayo sokusebenza ukuthi i-pair of rubber rings yakha isikhala esivaliwe nge-cavity (kodwa hhayi ukuthintana ne-shaft) ngaphansi kokusekelwa kwamasongo ensimbi.Lapho uzungezisa, izindawo ezimbili ezingaphansi kwezindandatho zensimbi ziyahambelana futhi ziyashelelana, ziqinisekisa ukusebenza kahle ngakolunye uhlangothi, futhi zivalwa ngempumelelo othulini lwangaphandle, amanzi, udaka, njll., ukuvikela amafutha okugcoba angaphakathi ekuvuzeni.
Umgomo wokuvala uphawu lwamafutha antantayo ukuthi ukuguqulwa kwamasongo amabili antantayo okubangelwa ukucindezelwa kwe-axial ye-O-ring kukhiqiza amandla acindezelayo ebusweni bokuphela kokuvala kwendandatho entantayo.Ngokugqokwa kweyunifomu yobuso bokuphela kokuvala, amandla anwebekayo agcinwe yi-I-Rubber O-ringikhishwa kancane kancane, ngaleyo ndlela idlala indima yesinxephezelo se-axial.Indawo yokubeka uphawu ingagcina ukunamathela okuhle phakathi nesikhathi esimisiwe, futhi impilo yokuvala ejwayelekile ingaphezu kuka-4000h.
Iyantantauwoyela uphawuwuhlobo olukhethekile lophawu lwemishini olwakhiwe ukuze luvumelane nezimo zokusebenza ezinokhahlo.Inezinzuzo zokumelana nokungcola okuqinile, ukumelana nokugqoka, ukumelana nomthelela, ukusebenza okuthembekile, isinxephezelo esizenzakalelayo sokugqoka kobuso bokuphela, kanye nesakhiwo esilula.Isetshenziswa kakhulu emikhiqizweni yemishini yobunjiniyela, futhi isetshenziswa kabanzi kuma-conveyor ahlukahlukene, okokusebenza kokwelashwa kwesihlabathi, kanye nemishini kakhonkolo.Emishinini yokumba amalahle, isetshenziselwa ikakhulukazi i-sprocket kanye ne-reduction of scraper conveyors, kanye nendlela yokudlulisela, ingalo ye-rocker, isigubhu, nezinye izingxenye zemishini yezimayini yamalahle.Lolu hlobo lomkhiqizo wokubeka uphawu lubanzi futhi luvuthiwe ekusetshenzisweni kwemishini nemishini yobunjiniyela, kodwa kwezinye izimboni, ngenxa yokusetshenziswa okulinganiselwe, ukuntuleka kwedatha yethiyori eyisisekelo nolwazi lokusebenzisa, ukwehluleka okwenzeka ngesikhathi sokusetshenziswa kuvamile, okwenza kube nzima. ukuzuza umphumela olindelekile.
Gcina igebe elithile phakathi kwendandatho entantayo kanye ne-shaft ejikelezayo, engantanta ngokukhululekile, kodwa ayikwazi ukujikeleza nge-shaft ejikelezayo.Ingenza kuphela ukuslayida kwe-radial esintantayo futhi igcine ukugqama okuthile nesikhungo se-shaft ngaphansi kwesenzo samandla adonsela phansi.Lapho i-shaft iphenduka, uketshezi lokuvala (ngokuvamile uwoyela) lufakwa ngaphandle ukuze lwakhe ifilimu kawoyela esikhaleni esiphakathi kwe-shaft nendandatho entantayo.Ngenxa yesenzo samandla we-oyela wedge akhiqizwa ngesikhathi sokujikeleza kwe-shaft, inani elithile lokucindezela kwefilimu kawoyela ligcinwa ngaphakathi kwefilimu kawoyela, okuvumela indandatho entantayo ukuthi igcine ngokuzenzakalelayo "ukuqondanisa" nendawo ephakathi kwe-shaft, inciphisa kakhulu igebe futhi ngempumelelo. ukuthola ukuvala ukuvuza okuphakathi kwe-fluid.Izinzuzo zayo ukusebenza kokubekwa uphawu okuzinzile, ukwethembeka, nempilo ende yesevisi;Uhla lwepharamitha yokusebenza yophawu lubanzi ngokuqhathaniswa (nokucindezela kokusebenza okufika ku-30 MPa kanye nezinga lokushisa elisebenzayo lika -100 ~ 200 ℃);Ilungele ukuvala imidiya yegesi kuma-centrifugal compressor, futhi ayikwazi ukufeza ukuvuza endaweni yomoya, futhi ifanele ukuvala imidiya evuthayo, eqhumayo, enobuthi, neyigugu.Okubi ukuthi izidingo zokucubungula izindandatho ezintantayo ziphakeme, zidinga uhlelo olukhethekile lukawoyela wokuvala;Kuningi ukuvuza kwangaphakathi, kodwa kusengokwesimo sokujikeleza kwangaphakathi, okuhlukile ngokwekhwalithi nokuvuza kwezimpawu zemishini.Isetshenziswa kabanzi kuma-seal ashukumisayo kuma-compressor we-centrifugal.
