Ama-Mechanical seal adlala indima ebalulekile ezinhlelweni ezahlukahlukene zezimboni. Zivimbela ukuvuza koketshezi negesi kumishini ezungezayo njengamaphampu nama-compressor, iqinisekisa ukusebenza kahle nokuphepha. Imakethe yomhlaba wonke yezigxivizo zemishini kulindeleke ukuthi ifinyelele cishe ku-USD 4.38 billion ngo-2024, ngesilinganiso sokukhula esingaba ngu-6.16% minyaka yonke kusukela ngo-2024 kuya ku-2030. Lokhu kukhula kugqamisa ukubaluleka kwakho okwandayo kuzo zonke izimboni. Kunezinhlobonhlobo zezimpawu zemishini ezikhona, ngayinye yakhelwe ukuhlangabezana nezidingo nemibandela ethile yokusebenza, okuyenza ibaluleke kakhulu ekugcineni ukuthotshelwa kwemvelo kanye nokuthuthukisa umkhiqizo wezimboni.
OkuyisisekeloIzingxenye zeMechanical Seals
Izigxivizo zemishini zihlanganisa izingxenye ezimbalwa ezibalulekile ezisebenza ndawonye ukuvimbela ukuvuza kwemishini yezimboni. Ukuqonda lezi zingxenye kusiza ekukhetheni uphawu olulungile lwezinhlelo zokusebenza ezithile.
Izinto Eziyisisekelo Zokuvala
Izakhi eziyisisekelo zokuvala zakha umnyombo wezimpawu zemishini. Banomthwalo wemfanelo wokudala umgoqo omkhulu ngokumelene nokuvuza koketshezi.
Ukuzungezisa Izimpawu
Izigxivizo ezijikelezayo zixhunywe engxenyeni ejikelezayo yezinto zokusebenza, njenge-pump shaft. Zihamba ne-shaft, zigcina uphawu oluqinile ngokumelene nengxenye emile. Lokhu kunyakaza kubalulekile ekuvimbeleni ukuvuza ngenkathi kuvumela i-shaft ukuthi ijikeleze ngokukhululeka.
Izigxivizo Ezinganyakazi
Izigxivizo ezimile zihlala zingaguquki endaweni, ngokuvamile zixhunywe endlini yezinto zokusebenza. Zisebenza ngokubambisana nezimpawu ezijikelezayo ukuze zenze uhlelo oluphelele lokuvala. Isigxivizo esimile sinikeza indawo ezinzile lapho uphawu olujikelezayo lungacindezela khona, luqinisekise uphawu oluthembekile.
Izinto Zokuvala Kwesibili
Izakhi zokuvala zesibili zithuthukisa ukusebenza kahle kwezigxivizo zemishini ngokunikeza amandla engeziwe okuvala. Basiza ukunxephezela ukungaboni ngaso linye okuncane nokuhluka kwezimo zokusebenza.
O-izindandatho
Ama-O-rings ayizici eziyindilinga ze-elastomeric ezihlinzeka ngophawu olumile phakathi kwezindawo ezimbili. Zivame ukusetshenziswa ezimpawu zemishini ukuvimbela ukungcola kwangaphandle ukuthi kungangeni endaweni yokuvala. Ama-O-rings ahlukahlukene futhi angakwazi ukuzivumelanisa nezimo nosayizi abahlukahlukene, okuwenza afanelekele izinhlelo zokusebenza ezahlukene.
Ama-Gaskets
Ama-gaskets asebenza njengolunye uhlobo lwesici sokuvala sesibili. Ngokuvamile zenziwa ngezinto ezifana nerabha noma i-PTFE futhi zisetshenziselwa ukugcwalisa isikhala phakathi kwezindawo ezimbili. Ama-gaskets asiza ukuvimbela ukuvuza ngokwakha uphawu oluqinile, ikakhulukazi ezimeni eziguquguqukayo lapho ukunyakaza kungase kwenzeke.
Ezinye Izingxenye
Ngaphezu kwezakhi zokuvala eziyinhloko nezesibili, izimpawu zemishini zihlanganisa ezinye izingxenye ezifaka isandla ekusebenzeni kwazo.
Iziphethu
Iziphethu zidlala indima ebalulekile ekugcineni ingcindezi phakathi kwezimpawu eziphendukayo nezimile. Baqinisekisa ukuthi ama-seal ahlala exhumana, ngisho nalapho kukhona ukushintshashintsha kwengcindezi noma izinga lokushisa. Iziphethu zisiza ukwamukela noma yikuphi ukunyakaza kwe-axial, kuthuthukise ukwethembeka kophawu.
Izingxenye Zensimbi
Izingxenye zensimbi zinikeza ukusekelwa kwesakhiwo sezimpawu zemishini. Zihlanganisa izingxenye ezifana nezindlu zensimbi kanye nezigcini ezibamba izimpawu endaweni. Lezi zingxenye zenzelwe ukumelana nezimo ezinzima ezivame ukuhlangana nazo ezindaweni zezimboni, ziqinisekisa impilo ende nokuqina kophawu.
Ukuqonda izingxenye eziyisisekelo zezigxivizo zemishini kubalulekile ekukhetheni uhlobo olufanele lwezinhlelo zokusebenza ezithile zezimboni. Ingxenye ngayinye idlala indima ebalulekile ekuqinisekiseni ukusebenza kahle nokuthembeka kophawu, ekugcineni kube neqhaza ekusebenzeni kahle kwezinto zonke.
Izinhlobo zeziMpawu zeMechanical
Izigxivizo zemishini ziza ngezinhlobo ezahlukene, ngayinye yakhelwe ukuhlangabezana nezidingo ezithile zokusebenza. Ukuqonda lezi zinhlobo kusiza ekukhetheni uphawu olufaneleka kakhulu lwezinhlelo zokusebenza ezihlukene zezimboni.
Izimpawu ze-Cartridge
Izigxivizo ze-Cartridge zinikeza isisombululo esihlanganiswe ngaphambili, ukwenza ukufakwa kube lula nokunciphisa ingozi yamaphutha. Bathuthukisa ukwethembeka
Izicelo kanye Nemibandela Yokukhetha
Izicelo zezimboni
Izigxivizo zemishini zithola ukusetshenziswa kakhulu emikhakheni yezimboni ehlukahlukene ngenxa yekhono lazo lokuvimbela ukuvuza nokugcina ubuqotho besistimu. Izimboni ezimbili ezivelele ezithembele kakhulu kuma-seal mechanical zihlanganisa ukucubungula amakhemikhali kanye nowoyela negesi.
Ukucubungula Amakhemikhali
Embonini yokucubungula amakhemikhali, izimvu zamanzi eziyimishini zidlala indima ebalulekile ekuqinisekiseni ukugcinwa okuphephile koketshezi oluyingozi. Zivimbela ukuvuza kwamaphampu nezixube, okubalulekile ekugcineni ukuphepha nokuhambisana nemvelo. Izigxivizo zisiza ekugcineni ubuqotho bemishini yenqubo ngokuvimbela ukungcoliswa nokuqinisekisa ukuthi amakhemikhali ahlala ngaphakathi kwezinhlelo ezimisiwe. Lolu hlelo lokusebenza lugqamisa ukubaluleka kokukhetha ama-seal akwazi ukumelana namakhemikhali anolaka namazinga okushisa ahlukahlukene.
Amafutha Negesi
Imboni kawoyela negesi idinga izixazululo eziqinile nezithembekile zokuvala ngenxa yezindawo ezinengcindezi ephezulu okuhlangatshezwane nazo ekubholeni nasekukhipheni. Izigxivizo zemishini zibalulekile ekuvimbeleni ukuvuza okungaholela ekuhlulekeni okuyinhlekelele noma ezingozini zemvelo. Isidingo esikhulayo sezimpawu zemishini ezihlala isikhathi eside nezisebenza kahle kulo mkhakha sigcizelela indima yazo ebalulekile ekugcineni ukuphepha nokusebenza kahle. Izimpawu ezisetshenziswa ekufakweni kukawoyela negesi kumele zibekezelele ukucindezela okukhulu namazinga okushisa, okwenza kubaluleke kakhulu ukukhetha izinto ezifanele kanye nemiklamo.
Imibandela Yokukhetha
Ukukhetha uphawu olufanele lomshini kuhilela ukucabangela izici ezimbalwa ukuze kuqinisekiswe ukusebenza kahle nokuphila isikhathi eside. Imibandela ebalulekile ihlanganisa izinga lokushisa nengcindezi, kanye nokuhambisana noketshezi.
Izimo Zezinga Lokushisa Nengcindezi
Izigxivizo zemishini kufanele zimelane nezimo ezithile zokushisa nezingcindezi zohlelo lokusebenza. Izindawo ezisezingeni eliphezulu zidinga ama-seal enziwe ngezinto ezingamelana nokuwohloka kokushisa. Ngokufanayo, izimpawu ezisetshenziswa ezinhlelweni zokucindezela okuphezulu kumele zakhelwe ukuphatha imithwalo ye-axial ngaphandle kokuphazamisa inte yazo.
