Iningimechanical shaft sealsayatholakala kuzo zombili izinguqulo ezilinganiselayo nezingalingani.Zombili zinezinzuzo kanye nokubi.
Iyini ibhalansi ye-seal futhi kungani ibaluleke kangakauphawu lomshini?
Ibhalansi yophawu isho ukusatshalaliswa komthwalo ebusweni bophawu.Uma kunomthwalo omningi ebusweni bophawu, kungaholela ekuvuzeni koketshezi ngaphakathi kophawu okwenza uphawu lungabi namsebenzi.Ngaphezu kwalokho, ifilimu ewuketshezi phakathi kwezindandatho zophawu ibeka engcupheni yokuhwamuka.
Lokhu kungase kubangele ukuguga okuphakeme futhi kudabuke isigxivizo, kunciphise ubude bayo bempilo.Ngakho-ke ukulinganisa kwezimpawu kuyadingeka ukuze kugwenywe izinhlekelele kanye nokwelula impilo yophawu.
Ama-Balanced Seals:
Uphawu olulinganiselayo lunomkhawulo ophakeme kakhulu wokucindezela.Kusho ukuthi zinamandla amakhulu okucindezela futhi zikhiqiza ukushisa okuncane.Bangakwazi ukuphatha uketshezi olunokuthambisa okuphansi kangcono kunezimpawu ezingalingani.
Izimpawu Ezingalingani:
okwamanje,izigxivizo zemishini ezingalinganingokuvamile zizinzile kakhulu kunozakwabo abalinganiselayo mayelana nokudlidliza, i-cavitation nokungahambi kahle.
Okuwukuphela kwe-drawback eyinhloko evezwa uphawu olungalingani umkhawulo wengcindezi ephansi.Uma zifakwa ngaphansi kwengcindezi engaphezulu ngisho nangaphezu kwalokho ezingayithatha, ifilimu ewuketshezi izohwamuka ngokushesha futhi ibangele ukuthi uphawu olugijimayo lome bese luhluleka.
Umehluko phakathi kwezimpawu ezilinganiselwe nezingalingani:
• Izimpawu ezilinganiselayo = Ngaphansi kuka-100%
Izigxivizo ezilinganiselwe zinesilinganiso sebhalansi esingaphansi kwamaphesenti angu-100, ngokuvamile, ziphakathi kwamaphesenti angu-60 no-90.
• Izimpawu Ezingalingani = Ngaphezu kuka-100%
Izimpawu ezingalingani zinesilinganiso sebhalansi esingaphezu kwamaphesenti angu-100, ngokuvamile, siphakathi kwamaphesenti angu-110 namaphesenti angu-160.
Uma ungenawo umqondo wokuthi yiziphi izimpawu zemishini ezifanele ukupompa, ungaxhumana nathi ukuze uthole imininingwane eyengeziwe, sizokusiza ukukhetha izimpawu ezifanele zemishini.
