Izinto ezifanele ze-mechanical seal zizokujabulisa ngesikhathi sokufaka isicelo.
Ama-seal angama-Mechanical angasetshenziswa ezinhlobonhlobo zezinto kuye ngokusetshenziswa kwezimpawu.Ngokukhetha impahla efanele yakhofutha uphawu, izohlala isikhathi eside, ivimbele ukugcinwa nokwehluleka okungadingekile.
Yiziphi izinto ezisetshenziselwauphawu lomshinis?
Izinto ezihlukahlukene zingasetshenziselwa izigxivizo ngokuya ngezidingo nendawo ezizosetshenziselwa yona.Ngokucabangela izinto ezibonakalayo ezifana nokuqina, ukuqina, ukunwetshwa kokushisa, ukuguga nokumelana namakhemikhali, uyakwazi ukuthola into efanelekile yophawu lwakho lomshini.
Lapho izigxivizo zemishini ziqala ukufika, ubuso be-seal ngokuvamile benziwa ngezinsimbi ezifana nezinsimbi eziqinile, ithusi nethusi.Ngokuhamba kweminyaka, izinto ezingavamile ziye zasetshenziselwa izinzuzo zazo zezakhiwo, okuhlanganisa izitsha zobumba kanye namabanga ahlukahlukene amakhabhoni ayimishini.
Uhlu lwezinto ezijwayelekile kakhulu zobuso be-seal
Ikhabhoni (CAR) / Ceramic (CER)
Le nto ngokuvamile iqukethe u-99.5% we-aluminium oxide enikeza ukumelana okuhle kokuhuzuka ngenxa yokuqina kwayo.Njengoba i-carbon ingasebenzi ngamakhemikhali ingakwazi ukumelana namakhemikhali amaningi ahlukene, nokho ayifaneleki uma 'ithuthumela' ngokushisa.Ngaphansi kwezinga lokushisa elibi kakhulu lingaphahlazeka noma liqhekeke.
I-Silicone Carbide (SiC) ne-sintered silicone carbide
Le nto yenziwa ngokuhlanganisa i-silica ne-coke futhi ifana ngamakhemikhali ne-Ceramic, nokho inezimfanelo zokugcoba ezithuthukisiwe futhi inzima kakhulu.Ukuqina kwe-silicone carbide kuyenza ibe yisixazululo esihle kakhulu sokugqokwa kanzima ezindaweni ezinokhahlo futhi ingaphinda igqitshwe futhi ipholishwe ukuze ilungise uphawu izikhathi eziningi empilweni yayo.
I-Tungsten Carbide (TC)
Impahla ehlukahlukene kakhulu efanai-silicone carbidekodwa ifaneleka kakhulu izicelo zokucindezela okukhulu ngenxa yokuba nokunwebeka okuphezulu uma kuqhathaniswa.Lokhu kuvumela 'ukuguquguquka' kancane futhi kuvimbele ukuhlanekezela kobuso.NjengeSilicone Carbide ingaphinde igqitshwe futhi ipholishwe.
