Zonke seals mechanical kudingeka ukugcinamechanical seal ubusos ivaliwe ngenxa yokungabikho kwengcindezi ye-hydraulic. Izinhlobo ezahlukene zeziphethu zisetshenziswa ezimpawu zemishini.
Intwasahlobo eyodwauphawu lomshiniuma kuqhathaniswa nekhoyili esindayo uma kuqhathaniswa, ingamelana nokugqwala kwezinga eliphezulu futhi ayivaleki uketshezi lwe-viscous. Amandla e-Centrifugal angase athambekele ekukhululeni amakhoyili. Iziphethu ezilodwa zivame ukudinga isikhala se-axial esengeziwe kanye nezimpawu zemishini ezinosayizi abahlukene zidinga iziphethu ezinosayizi abahlukene.
Iziphethu eziningingokuvamile zincane kuneziphethu zodwa, ezihlinzeka ngomthwalo omfaniswano owengeziwe ebusweni bophawu. Izigxivizo eziningi ezinobukhulu obuhlukahlukene zingasebenzisa iziphethu ezifanayo kuphela ngokushintsha izinombolo zamakhoyili eziphethu. Intwasahlobo eminingi imelana nokuhlehlisa kusuka ku-centrifugal force kune-spring yekhoyili eyodwa enamandla asebenza ngendlela ehlukile. Kodwa intambo encane yesiphambano. yemithombo emincane yenza ukuthi imithombo emincane ingamelani nokugqwala futhi ivaleke
A wave spring mechanical sealsidinga isikhala esincane se-axial kunomklamo wentwasahlobo kaningi. Kodwa kufanele kwenziwe amathuluzi akhethekile ukuze kufinyelelwe emiphumeleni engcono kakhulu yokukhiqiza, ngaphandle kokushisa okudingekayo kulo mklamo kukhawulela izinto ezisetshenziswayo ezisezingeni eliphezulu zensimbi engagqwali kanye namaqembu e-Hastelloy. Okwesithathu, ushintsho olukhulu ekulayisheni kokuchezuka okunikeziwe kufanele kubekezelelwe. Ukulahlekelwa okukhulu kwamandla noma ukuzuza ngamandla ngokuqhathaniswa nokuhamba kwe-axial encane kufanele kulindelwe.
Iwashaiyisiphethu esiqine kakhulu; empeleni, inkinga evamile nge-washer ukuthi izinga lentwasahlobo liphezulu kakhulu. Ukunciphisa izinga lentwasahlobo, ama-washers ahlanganiswe.
kubhodlaInhlanganisela ye-spring and second sealing element iwukubhodla kwensimbi. Kukhona izifutho ezishiselwe onqenqemeni zensimbi kanye nezifutho ezakhiwe. Izifutho ezibunjiwe zisetshenziselwa ukwehlisa inani lokushisela ngezifutho ezakhiwe zibe izinga eliphezulu kakhulu lentwasahlobo kunezifutho ezishiselwe. Ukukhethwa kokuqina kwe-bellow kwenziwa ngokuvumelana nokumelana nokucindezela ngaphandle kwezinga lentwasahlobo elidlulele. Kubalulekile ukukhetha indlela yokushisela kanye nesimo se-bellows ukuze uthole impilo yokukhathala okukhulu.
