Iiseal eziqhekekileyo zisisombululo esitsha sokutywina kwiindawo apho kunokuba nzima ukuzifaka okanye ukutshintsha iiseal zemveli zoomatshini, njengezixhobo ezinzima ukufikelela kuzo. Zikwalungele ukunciphisa ixesha lokungasebenzi elibizayo lezinto ezibalulekileyo kwimveliso ngokoyisa ubunzima bokuhlanganisa kunye nokuqhaqha okuhambelana nezixhobo ezijikelezayo. Iiseal ezininzi zoomatshini eziqhekekileyo neziqhekekileyo ziye zayilwa ngabavelisi abahlukeneyo, nangona kunjalo, ngezinketho ezininzi ezikhoyo kwimarike, wazi njani ukuba loluphi ukhetho olufanelekileyo kwisicelo sakho?
Imingeni
Nangona uyilo oluninzi lunokufezekisa injongo yokunciphisa ixesha elifunekayo ukutshintsha isitywina soomatshini, luye lwazisa ezinye iingxaki. Ezi ngxaki zoyilo zibangelwa zizinto ezimbalwa:
• Ezinye iindlela zoyilo lwezitywino eziqhekekileyo ezineenxalenye ezininzi ezikhululekileyo ekufuneka ziphathwe ngononophelo olukhulu.
• Ukufakelwa kunokufuna imilinganiselo echanekileyo okanye ukusetyenziswa kwee-shims ezahlukeneyo okanye izixhobo ezikhethekileyo ukuze kulungiswe ngokuchanekileyo kwaye kubekwe indibano yesitywina soomatshini kwi-shaft ejikelezayo.
• Ezinye izitywini zisebenzisa indlela yokubambelela yangaphakathi, nto leyo ethintela amandla okubamba i-torsional kunye ne-axial ukuze zifumane isitywini kwisixhobo.
Enye ingxaki enokubakho xa indawo yeshaft kufuneka ilungiswe emva kokuba itywiniwe. Kwiindlela ezithile zoyilo, izikrufu ezisetyenzisiweyo zitshixa indibano yendandatho yesitywina ejikelezayo kwishaft kwaye azinakufikelelwa emva kokuba iindibano ezimbini ze-standalone gland zibotshiwe kunye.
Oku kuthetha ukuqhaqhwa ngokupheleleyo kwesitywina xa sele sifakiwe, nto leyo eshiya umsebenzisi wokugqibela enoxanduva lokuqinisekisa ukuba isitywina esintsonkothileyo esinobuso obudibeneyo ngokuchanekileyo sihlanganiswe ngokuchanekileyo kwipompo.
Isisombululo seFlexaseal
I-Flexaseal ijongana nezi ngxaki kunye nemida nge-Style 85 two-piece split cartridge mechanical seal assembly. I-Style 85 split seal inee-unitized, self-contained assemblys ezimbini kuphela ezidibana phezu kwe-shaft ukuze zenze uyilo lwe-self-setting kunye ne-self-aligning cartridge seal.
Olu yilo lwe-cartridge mechanical seal oluhlukaniswe ngokupheleleyo lususa ukuphathwa kwezinto ezininzi ezikhululekileyo, ezithambileyo, nezichanekileyo ezenziweyo.
kwaye ivumela ukufakwa okulula kakhulu, okulula nokonga ixesha ngaphandle kokulinganisa okanye ukuqikelela. Ubuso obuphambili bokuvala bubanjwe kunye kwaye bugcinwe ngokukhuselekileyo ngaphakathi kweendawo ezimbini ze-gland eziqhekekileyo kunye ne-sleeve, zikhuselekile kakuhle kuyo nayiphi na indlela yokuphatha kakubi, ukungcola okanye ukungcola.
Iingenelo
• Eyona ndlela ilula yokufaka nayiphi na itywina elahlulweyo emhlabeni: ncamathisela nje iihafu ezimbini ze-cartridge phezu kwe-shaft uze uzifake kwipompo njengayo nayiphi na enye itywina ye-cartridge.
• Itywina lokuqala lomatshini wekhatriji elahlulweyo emhlabeni apho kubanjwa khona iziqwenga ezibini kuphela: ubuso obudibeneyo buqiniswe ngokukhuselekileyo kwiinxalenye zekhatriji kwaye abunakuqhotyoshwa okanye kuqhekeke.
• Yahlulahlula kuphela isitywina somatshini sekhatriji apho i-impeller inokulungiswa khona ngaphandle kokususa isitywina: faka nje kwakhona iikliphu zokuseta, khulula iiskrubhu zokuseta kwaye ulungise indawo ye-impeller uze uqinise kwakhona iiskrubhu zokuseta kwaye ususe iikliphu.
• Kuphela sitywino somatshini sekhatriji esahluliweyo esihlanganiswe ngokupheleleyo, kwaye uxinzelelo luvavanyiwe kumzi-mveliso: ukuthembeka kokutywina kuqinisekiswa ngaphambi kokuba kuthunyelwe ebaleni, ngaloo ndlela kuqinisekiswa izinga eliphezulu lempumelelo kufakelo ngalunye.
• Akukho milinganiselo, akukho shims, akukho zixhobo zikhethekileyo, kwaye akukho glue: iikliphu zokuseta iikhatriji ziqinisekisa ukulungelelaniswa okufanelekileyo kwe-axial kunye ne-radial ukuze kube lula ukufaka
Uyilo lweSitayile 85 alufani nezinye ezikhoyo kwimarike. Nangona uninzi lwezitywino zoomatshini eziqhekekileyo zifakelwe ngaphandle kwebhokisi yokuzalisa kwaye zenzelwe ukusebenza njengesitywino sangaphandle, iSitayile 85 yenziwe njengetywino yoomatshini yekhatriji yokwenyani, eqhekekileyo ngokupheleleyo. Luyilo oluzinzileyo lwe-hydraulically, oluzinzileyo olunezipringi ezininzi olufakelwe kakhulu ngaphandle kwebhokisi yokuzalisa.
Ezi mpawu zivumela amandla e-centrifugal ukuba agcine izinto eziqinileyo kude nobuso besitywino ngelixa egcina amandla okusingatha isantya esiphezulu, uxinzelelo lwangaphakathi kunye nokungahambi kakuhle. Akukho mfuneko yokukhathazeka ngezinto eziqinileyo, njengoko izipringi zikhuselekile kwaye zingaphandle kwemveliso ukuze kuthintelwe ukuvaleka.
