I-Centrifugal Pump Seal Basics
Amaphampu we-centrifugalIsetshenziswa kabanzi kwizimboni ezahlukahlukene, kufaka phakathi uwoyela kanye negesi, ukucubungula kwamakhemikhali, ukwelashwa kwamanzi, kanye nesizukulwane samandla, ukuthutha uketshezi oluyimpumelelo. Enye yezinto ezibucayi zephampu ye-centrifugal uhlelo lokubopha uphawu, oluvimbela ukuvuza koketshezi olugcwele futhi luqinisekise ukuthi iphampu lisebenza ngokuphepha nangendlela efanele. Phakathi kwezinhlobo ezahlukene zamasistimu wokubopha uphawu, izimpawu ezimbili zemishini zivame ukusetshenziswa kuzinhlelo zokusebenza lapho ukuvimbela ukuvuza kubaluleke kakhulu. Kodwa-ke, amazinga okushisa aphezulu angafaka izinselelo ezibucayi ebuqothweni bezinhlelo eziphindwe kabili, okuholela ekukhuphukeni okuyingozi ekucindezelweni nasekuphulukeni okuyinhlekelele.
Izisekelo zezimpawu zamapompo we-centrifugal
Izilongezo zemishini ziwuhlobo oluvame kakhulu lohlelo lokufaka uphawu olusetshenziswa kumaphampu we-centrifugal. Ziqukethe izinto ezimbili eziyinhloko: ubuso be-seal state kanye nobuso be-boal ojikelezayo, obucindezelwa ndawonye ukudala uphawu oluqinile. Ubuso bophawu buvame ukwenziwa ngezinto ezihlala isikhathi eside njengekhabhoni, i-ceramic, noma i-silicon carbide, engamelana nezimo ezinzima ngaphakathi kwephampu. Inhloso eyinhloko yophawu ukuvimbela uketshezi olugcwele olusuka ekuvuzeni ukuphuma kwephampu ngenkathi futhi nokugcina izinto ezingcolile zingangeni ohlelweni.
Ezinhlelweni ze-Mechanical Seal Seal, isethi eyodwa yobuso be-seal isetshenziselwa ukuqukatha uketshezi. Kodwa-ke, kuzinhlelo zokusebenza ezibandakanya uketshezi olunobungozi, olunobuthi, noma oluphezulu lwengcindezelo, uhlelo lwe-macheccal seal oluphindwe kabili luvame ukuqashwa. Izimpawu ezimbili eziphindwe kabili ziqukethe amasethi amabili obuso bobuso obuhlelwe ngokucushwa noma ukubuyela emuva emuva, ngoketshezi lwesithiyo phakathi kwabo. Lo mklamo uhlinzeka ngesendlalelo esengeziwe sokuvikelwa ekuvuzweni nasekukhuliseni ukuthembeka kohlelo lokufaka uphawu.
Izinhlelo ze-Double Seal kanye nezinzuzo zazo
Izilonda eziphindwe kabili zemishini zinenzuzo ikakhulukazi kuzinhlelo zokusebenza lapho ukuvimbela ukuvuza kubalulekile. Uketshezi lwesithiyo phakathi kwalezi zindawo ezimbili zobuso bophawu lusebenza njenge-buffer, ukuvimba uketshezi olunamampunge ngenxa yokuphunyuka emvelweni. Ngaphezu kwalokho, uketshezi lwesithiyo lusiza ekugcobeni futhi lupholise ubuso bendawo, ukunciphisa ukugqoka kanye nokunweba impilo yezimpawu zakwezimpawu. Izimpawu eziphindwe kabili zisetshenziswa kakhulu kuzinhlelo zokusebenza ezibandakanya izingcindezi eziphakeme, amazinga okushisa aphezulu, uketshezi olulimazayo, noma uketshezi oluyingozi yemvelo.
Kunezinhlobo ezimbili eziphambili zokucushwa kwe-Double Seal:
Ama-Tandem Seals: Kulokhu kucushwa, uphawu oluyisisekelo lubhekene noketshezi olugcwele, kuyilapho uPrive Secondary usebenza njengesipele uma kuvela uphawu oluyisisekelo. Uketshezi lwesithiyo uvame ukugcinwa engcindezini ephansi kunoketshezi olugcwele ukuqinisekisa ukuthi noma yikuphi ukuvuza kugeleza ngaphakathi kubheke ephampu.
Izimpawu zangemuva emuva emuva: Kuleli lungiselelo, amasethi amabili obuso bophawu athambekele emaphaketheni ahlukile, ngoketshezi lwesithiyo agcinwe engcindezini ephakeme kunoketshezi olugcwele. Lokhu kucushwa kuvame ukusetshenziswa kuzinhlelo zokusebenza ezibandakanya uketshezi oluguquguqukayo noma oluyingozi.
Umthelela wamazinga okushisa aphezulu ezinhlelweni ze-Double Seal Seal
Ngenkathi izinhlelo ze-Double Seal Seal zinikeza izinzuzo ezibalulekile, azivikelekile ezinseleleni ezibangelwa amazinga okushisa aphezulu. Amazinga okushisa aphezulu angavela emithonjeni ehlukahlukene, kufaka phakathi uketshezi olugcwele, imvelo esebenzayo, noma ukuxabana phakathi kobuso bendawo. Lapho amazinga okushisa akhuphuka, kungavela izingqinamba eziningana ezokwehlela ubuqotho bohlelo lwe-seal:
Ukunwetshwa kwe-Thermal:Amazinga okushisa aphezulu abangela izinto zobuso be-seal kanye nezinye izingxenye ukuze zikhule. Uma ukwandiswa okushisayo kungafani, kungaholela ekulweni nokuphathwa kabi kobuso bendawo, okuholele ekuphumeni okuvuvukala noma ukwehluleka kwesicavilo.
Ingcindezi eyandayo e-Barrier Fluid:Ohlelweni lwe-Seal Seal, uketshezi lwesithiyo lubalulekile ukuze kugcinwe ubuqotho bophawu. Kodwa-ke, amazinga okushisa aphezulu angenza ukuthi uketshezi lwesithiyo ukukhulisa, okuholela ekukhuphukeni okuyingozi kokucindezela ngaphakathi kwegumbi leseli. Uma ingcindezi idlula umkhawulo wokuqamba wohlelo lwe-seal, kungadala ukuthi izimpawu zehluleke, ziholele ekuvuzeni noma ekulimaleni okuyinhlekelele ephampu.
Ukuwohloka kwezinto zokwehla kwezinto:Ukuchayeka isikhathi eside kumazinga okushisa aphezulu kungadala ukuthi izinto ezisetshenziswe obhekene nobuso be-seal defade. Isibonelo, ama-elastomers asetshenziswa kuma-O-rings noma ama-gaskets angaqina noma aqhekeke, kuyilapho ubuso be-carbon noma ubumba bungase bube brittle. Lokhu kusulwa kungaphazamisa amandla we-Seal wokugcina umgoqo oqinile, okuholela ekuvuzweni.
I-Vaporrization of the Barrier Fluid:Ezimweni ezimbi kakhulu, amazinga okushisa aphezulu angadala uketshezi lwesithiyo ukuze luhlangane, kwakha amaphakethe egesi ngaphakathi kwegumbi leseli. Lawa maphakethe wegesi angaphazamisa ukugcotshwa kanye nokupholisa kobuso bendawo, okuholela ekushayweni okwengeziwe, ukugqoka kanye nokwehluleka kokugcina kwalo.
Ukunciphisa ubungozi bokushisa okuphezulu
Ukuvimbela imiphumela emibi yamazinga okushisa aphezulu ezinhlelweni ze-Double Seal Seal, kungathathwa izinyathelo eziningana:
Ukukhethwa Kwezinto Ezifanele:Ukukhetha izinto zokwakha seal ezingamelana namazinga okushisa aphezulu kubalulekile. Isibonelo, ama-elastomers angaphansi komhlaba aphezulu anjenge-fluorocarbon noma i-mpororooroolastomer (i-FFKM) ingasetshenziselwa ama-o-ring, ngenkathi ama-ceramics athuthukile noma i-silicon carbide ingasetshenziselwa ubuso be-sal.
Bheka isilinganiso sebhalansi:Ukukhetha uphawu lwenzelwe ukucindezelwa okuphezulu kwe-lowolate uketshezi oPhweni lokuqala.
Izinhlelo Zokupholisa:Ukufaka amasistimu wokupholisa, njengokushintshana kokushisa noma amajakethi okupholisa, kungasiza ekunciphiseni ukushisa futhi ulondoloze izinga lokushisa loketshezi lwesithiyo ngaphakathi kwemingcele ephephile.
Ukuphathwa Kwengcindezi:Ukuqapha kanye nokulawula ingcindezi ka-Barrier Fluid kubalulekile ukuvikela ukucindezelwa okuyingozi. Ama-valves wokusiza amangcindezi noma amasistimu wokulawula ingcindezi angafakwa ukuze alondoloze uketshezi lwesithiyo engcindezini efanelekile.
Ukulungiswa okujwayelekile:Ukuhlolwa njalo nokunakekelwa kohlelo lwe-Seal kungasiza ekuboneni nasekubhekeni izingqinamba ngaphambi kokuholela ekwehlulekeni. Lokhu kufaka ukubheka izimpawu zokugqoka, ukuphakamiseka, noma ukonakaliswa kwezinto zokwenziwa kwezinto.
Ukugcina
Tkflo centrifugal pumpIzimpawu, ikakhulukazi izilombu ezisebenza ngemishini eziphindwe kabili, zidlala indima ebalulekile ekuqinisekiseni ukusebenza okuphephile nokusebenzayo kwamaphampu ezicelo ezifunwayo. Kodwa-ke, amazinga okushisa aphezulu angabeka ubungozi obukhulu ebuqothweni bezinhlelo ze-Double Seal, okuholele ekucindezelweni okwengeziwe, ukucekelwa phansi kwezinto ezibonakalayo, kanye nokwehluleka kwesikhala. Ngokuqonda izisekelo eziyisisekelo ze-Centrifugal Pump Seals futhi zisebenzisa izindlela ezifanele zokunciphisa imiphumela yokushisa okuphezulu, abasebenza ngokufanele bangaqhakambisa ukuthembeka nokuphila isikhathi eside kwezinhlelo zabo zepompo. Ukukhethwa Kwezinto Ezifanele, Izinhlelo Zokupholisa, Ukuphathwa Kwengcindezi, kanye Nokulondolozwa Okujwayelekile Yizo zonke izingxenye ezibalulekile zecebo eliqinile lokubhekana nezinselelo ezibangelwa amazinga okushisa aphezulu.
