Izivalo ezihlukanisiwe ziyisisombululo sokuvala esisha sezindawo lapho kungaba nzima ukufaka noma ukufaka esikhundleni izivalo ezivamile zemishini, njengemishini enzima ukufinyelela kuyo. Zilungele futhi ukunciphisa isikhathi sokungasebenzi esibizayo sezimpahla ezibalulekile ekukhiqizeni ngokunqoba ubunzima bokuhlanganisa nokuqaqa obuhambisana nemishini ejikelezayo. Izivalo eziningana zemishini ezihlukanisiwe ngokuphelele zaklanywa abakhiqizi abahlukahlukene, nokho, ngezinketho eziningi kangaka ezitholakala emakethe wazi kanjani ukuthi yikuphi ukukhetha okungcono kakhulu kwesicelo sakho?
Izinselele
Nakuba imiklamo eminingi ingafinyelela umgomo wokunciphisa isikhathi esidingekayo ukushintsha uphawu lomshini, iye yaletha ezinye izinkinga. Lezi zinkinga zokuklama ezingokwemvelo zingabangelwa izici ezimbalwa:
• Eminye imiklamo yesitayela sezingxenye ezihlukanisiwe inezingxenye eziningana ezikhululekile okumele ziphathwe ngokucophelela okukhulu.
• Ukufakwa kungadinga izilinganiso eziqondile noma ukusetshenziswa kwama-shim ahlukahlukene noma amathuluzi akhethekile ukuze kulungiswe kahle futhi kubekwe i-mechanical seal assembly ku-rotation shaft
• Ezinye izivalo zisebenzisa indlela yokubopha yangaphakathi, zinciphisa amandla okubamba e-torsional kanye ne-axial ukuze kutholakale kahle isivalo emshinini.
Okunye ukukhathazeka okungaba khona kuvela lapho indawo yomgodi kufanele ilungiswe ngemva kokuthi uphawu selusethiwe. Kweminye imiklamo, izikulufo ezisethiwe zikhiya i-rotary seal ring assembly ku-shaft futhi azikwazi ukufinyelelwa ngemva kokuba i-stainless gland assembly ezimbili sezihlanganiswe ndawonye.
Lokhu kusho ukuhlukaniswa okuphelele kwesivalo uma sesifakiwe, okushiya umsebenzisi wokugcina enesibopho sokuqinisekisa ukuthi isivalo esiyinkimbinkimbi esinobuso obugobile kahle sihlanganiswe kabusha kahle epompo.
Isixazululo se-Flexaseal
I-Flexaseal ibhekana nalezi zingqinamba kanye nemikhawulo nge-Style 85 two-piece split cartridge mechanical seal assembly. I-Style 85 split seal inezinhlaka ezimbili kuphela ezihlanganisiwe, ezizimele ezihlangana ndawonye phezu kweshafti ukuze zakhe umklamo we-cartridge seal ozibekela wona kanye nozilungisa wona.
Lo mklamo wokuvala ohlanganisiwe ngokuphelele wekhatriji uqeda ukuphathwa kwezingxenye eziningi ezikhululekile, ezithambile, nezinembile ezenziwe
futhi ivumela ukufakwa okulula kakhulu, okulula nokonga isikhathi ngaphandle kokulinganisa noma ukuqagela. Ubuso obubalulekile bokuvala bubanjwe ndawonye futhi bugcinwe ngokuphephile ngaphakathi kwezingxenye ezimbili ze-gland ezihlukanisiwe kanye ne-sleeve, buvikelwe kahle kunoma yikuphi ukuphathwa kabi, ukungcola noma ukungcola.
Izinzuzo
• Ukufakwa okulula kakhulu kwanoma yiluphi uphawu oluhlukanisiwe emhlabeni: mane unamathisele izingxenye ezimbili zekhatriji phezu komgodi bese uzifaka epompo njenganoma yiluphi olunye uphawu lwekhatriji
• I-cartridge mechanical seal yokuqala ehlukanisiwe emhlabeni lapho kusingathwa khona izingcezu ezimbili kuphela: ubuso obugobile buqiniswe ngokuphephile ngama-cartridge halves futhi abukwazi ukugoqwa noma ukuqhekezwa
• I-cartridge mechanical seal ehlukanisiwe kuphela lapho i-impeller ingalungiswa khona ngaphandle kokususa i-seal: mane nje ufake kabusha iziqeshana zokusetha, ukhulule izikulufo zokusetha bese ulungisa indawo ye-impeller bese uqinisa kabusha izikulufo zokusetha bese ususa iziqeshana.
• Kuphela uphawu lomshini lwekhatriji oluhlukanisiwe oluhlanganiswe ngokuphelele, kanye nengcindezi evivinywe efektri: ubuqotho bokuvala buyaqinisekiswa ngaphambi kokuthunyelwa ensimini, ngaleyo ndlela kuqinisekiswa izinga eliphezulu lempumelelo ekufakweni ngakunye.
• Akukho zilinganiso, akukho shims, akukho mathuluzi akhethekile, futhi akukho glue: iziqeshana zokusetha i-cartridge ziqinisekisa ukulungiswa okufanele kwe-axial kanye ne-radial ukuze kube lula kakhulu ukufaka
Umklamo weSitayela 85 awufani nanoma yimuphi omunye emakethe. Nakuba izivalo eziningi zemishini ezihlukanisiwe zifakwa ngaphandle kwebhokisi lokugxusha futhi zenzelwe ukusebenza njengesivalo sangaphandle, iSitayela 85 sakhiwe njengesivalo semishini sekhatriji sangempela, esihlukaniswe ngokuphelele. Siwumklamo we-hydraulic olinganiselayo, ongashintshi we-multi-spring ofakwe ngokuyinhloko ngaphandle kwebhokisi lokugxusha.
Lezi zici zivumela amandla e-centrifugal ukuthi agcine izinto eziqinile kude nobuso besivalo ngenkathi egcina ikhono lokusingatha isivinini esiphezulu, ukucindezeleka kwangaphakathi kanye nokungahambisani kahle. Asikho isidingo sokukhathazeka ngezinto eziqinile, njengoba izipilingi zivikelwe futhi zingaphandle komkhiqizo ukuze kuqedwe ukuvaleka.
