Seal Izinketho
I-Glond seal - Uhlobo oludume kakhulu lwe-seal. Amanzi ahlanzekile ngomfutho othile ajovwe ekupakisheni ngesinqamuleli selambu, avimbele ukuvuza ekugoqeni. Isakhiwo esilula, ukugcinwa okulula kanye nezindleko eziphansi, ezifanele lapho uphawu lwe-expeller lungafaneleki khona.
I-Expeller seal- I-expoller ikhiqiza amandla abuyele emuva we-centrifugal ukuvimbela ukuvuza. Ingasetshenziselwa iphampu yesiteji esisodwa noma iphampu yokuqala yamaphampu amaningi ochungechungeni lapho ingcindezi eqondile ohlangothini lokumunca inkulu kunaleyo ohlangothini lokuphuma ingekho ngaphezu kuka-10%. Awekho amanzi e-gland adingekayo, i-slurry ngeke ihlanjululwe futhi umphumela wokuvala uthembekile, osetshenziswa lapho ukuhlanjululwa kwe-slurry kungavunyelwe.
Mechanical seal - Ifanele ukusetshenziswa lapho kungekho nto eyengeziwe evunyelwe ukuxuba noketshezi olumpontshwayo, njengamakhemikhali noma imboni yokudla.
Isici sesakhiwo
★ I-diameter enkulu ene-overhang emfushane iqinisekisa ukuqina kwe-shaft, efanelekile esimweni samandla aphezulu.
★ Umkhono weshafu wensimbi engenasici oqinile onezigxivizo zendandatho ethi 'O' emikhawulweni yomibili. I-slip fit ivumela umkhono uvikele i-shaft ekuguge nasekugqwaleni.
★ Amaphini e-vanes kukho kokubili ikhava yangaphambili nengemuva ye-Impeller akhulula ukucindezela kophawu futhi anciphise ukujikeleza kabusha.
★ I-Casing yenziwe nge-ductile iron, izimbambo zisiza i-casing ukuze ime ukucindezela okuphezulu.
★ Izingxenye ezimanzi zenziwe nge-high-chrom alloy noma irabha, enezinto ezimelana nokuqhunyiswa, ukumelana nokugqwala kanye nomthelela ekugugulekeni, okuthuthukise impilo yesevisi yephampu.
★ Izingxenye ezimanzi zenziwe ngensimbi noma irabha ziyashintshana noma zixube ukusetshenziswa, zifanele isimo sokusebenza esihlukile.
★ I-Impeller isebenzisa indlela yokugeleza okubanzi kanye ne-vane concave ukuze kuthuthukiswe ukugeleza nokumelana nokugqwala, kwelule impilo yesevisi.
★ Isigxivizo se-shaft singase sisetshenziswe njenge-packing seal, i-expeller seal kanye ne-mechanical seal ukuze ivumelane nezimo zokusebenza ezahlukene.
★ Igatsha lokukhipha lingamiswa ngezikhawu ze-45 degrees ngesicelo futhi liqondiswe kunoma yiziphi izikhundla eziyisishiyagalombili ukuze zivumelane nokufakwa kanye nezicelo.
★ I-Assembly ephethe i-grease lubrication kanye ne-oli lubrication iyakhethwa kuncike ekusetshenzisweni.
★ Yamukelwa umhlangano othwala uwoyela we-lubrication unganciphisa ngempumelelo izinga lokushisa eliphezulu lokusebenza futhi unciphise ukuthwala iphutha
★ I-grease lubrication ephethe umhlangano ukufakwa kalula nokulungiswa, isakhiwo esilula futhi kulula ukusigcina futhi senze ngokuthembekile.
