Lapho ngibona auphawu lomshiniesenzweni, ngizizwa ngigqugquzelwa isayensi ngemuva kwayo. Le divayisi encane igcina uketshezi ngaphakathi kwemishini, ngisho noma izingxenye zihamba ngokushesha.
- Onjiniyela basebenzisa amathuluzi afanaI-CFD ne-FEAukufunda amazinga okuvuza, ingcindezi, nokuthembeka.
- Ochwepheshe nabo bayakalai-torque yokushayisana kanye namazinga okuvuzaukuqinisekisa ukuthi zonke izimpawu zisebenza kahle kakhulu.
Okuthathwayo Okubalulekile
- Izimpawu zemishinidala umgoqo oqinile omisa ukuvuza kwamaphampu nemishini, ngisho nalapho izingxenye zihamba ngokushesha, zivikela izinto zokusebenza nendawo ezungezile.
- Ukukhetha izinto ezifanele kanye nohlobo lwama-seal kusiza ama-seal ahlale isikhathi eside, anciphise ukusetshenziswa kwamandla, kanye nezindleko zokunakekela eziphansi.
- Ukuhlolwa okuvamile nokunakekelwa okufanele kugcina izimpawu zemishini zisebenza kahle, zonga imali futhi zivimbele ukuwohloka.
Indlela I-Mechanical Seal Esebenza Ngayo
Isimiso sokusebenza se-Mechanical Seal
Uma ngibheka auphawu lomshini, ngibona ikhambi elihlakaniphile lenkinga enzima. Isigxivizo sidala ukuxhumana okuqinile phakathi kweshaft ehambayo kanye nendlu emile. Lesi sixhumanisi sigcina uketshezi ngaphakathi kwamaphampu, ama-mixers, noma ama-compressor, ngisho noma i-shaft ijikeleza ngesivinini esiphezulu. Ngikuthola kumangalisa ukuthi isayensi nobunjiniyela buhlangana kanjani lapha.
Ososayensi basebenzisa amamodeli ekhompiyutha ukuze bahlole ukuthi uketshezi luhamba kanjani nokuthi ukushisa kusakazeka kanjani ngaphakathi kwe-seal. Basebenzisa izibalo ukuze babikezele ukuthi uphawu luzosabela kanjani ezinguqukweni zokucindezela, isivinini, noma izinga lokushisa. Isibonelo, uma amandla acindezela uphawu abhekane ndawonye ashintsha ngo-4% kuphela, ubuso be-seal bungahamba ngaphezu kuka-34% ngaphezulu, futhi ukuvuza kungagxuma ngaphezu kuka-100%. Lezi zinombolo zibonisa ukuthi uphawu luzwela kangakanani endaweni yalo. Onjiniyela bahlola amamodeli abo ngokuhlolwa kwangempela kwempilo, ukukala amazinga okushisa namazinga avuzayo. Iimiphumela ihambisana eduze, okufakazela ukuthi isayensi ngemuva kophawu isebenza emhlabeni wangempela.
Izingxenye Eziyinhloko Zophawu Lomshini
Ngaso sonke isikhathi ngizizwa ngihlabeke umxhwele ngezingxenye ezakha uphawu oluwumshini. Ingxenye ngayinye inomsebenzi okhethekile, futhi ndawonye bakha umgoqo oqinile ngokumelene nokuvuza.
- Ubuso Bophawu Oluzungezayo: Le ngxenye ijikeleza nge-shaft. Kufanele ihlale ibushelelezi futhi isicaba.
- Ubuso be-Stationary Seal: Le ngxenye ihlala inganyakazi, icindezelwe ebusweni obujikelezayo.
- Izimpawu zesibili: Ama-O-rings noma ama-elastomers agcwalisa noma yiziphi izikhala ezincane futhi agcine uphawu luqinile.
- Spring noma Bellows: Lezi zidudula ubuso be-seal ndawonye, noma ngabe i-shaft ihamba kancane.
- Izingxenye Zensimbi: Lezi zibamba yonke into endaweni futhi zisize isigxivizo silingane nezinto zokusebenza.
Ukukhetha izinto ezibonakalayo kubaluleke kakhulu. Ngibonile izimpawu ezenziwe ngezitsha zobumba noma ama-carbides zihlala isikhathi esidekunemiklamo emidala. Lezi zinto zimelana nokugqoka nokushisa. Ama-O-rings kanye nezinto zokugcoba ezikhethekile zisiza uphawu lusebenze kahle iminyaka. Onjiniyela baklama ubuso ukuthi bucishe bulingane kahle futhi buhambisane. Lo mklamo ocophelelayo ugcina ukuvuza kuncane futhi usiza uphawu luhlale isikhathi eside.
Ithiphu:Lapho ukhetha uphawu lwemishini, hlola njalo izinto. Insimbi engagqwali isebenza kahle ekushiseni okuphezulu. I-PTFE imelana namakhemikhali anokhahlo.
Indlela Izimpawu Zemishini Zivimbela Ukuvuza
Ngikholwa ukuthi umlingo wangempela wophawu lwemishini kwenzeka esikhaleni esincane phakathi kobuso bezimpawu ezimbili. Ifilimu elincanyana lamafomu oketshezi lapha. Le filimu isebenza njenge-cushion, inciphisa ukungqubuzana nokuguga. Uma ifilimu ishubile kakhulu, ukuvuza kungenzeka. Uma izacile kakhulu, ubuso bungaguga ngokushesha. Onjiniyela bafunda ukuthi ubuso bunzima noma bushelelezi kangakanani, nokuthi ukushisa kulishintsha kanjani igebe. Basebenzisa ama-grooves akhethekile namaphethini ukulawula ifilimu ewuketshezi.
Ukuhlolwa kwamafekthri kubonisa ukuthi izimvu zamanzi ezintsha zigcina ukuvuza kuphansi kakhulu, ngisho nangaphansi kwengcindezi ephezulu. Ngemva kwezinkulungwane zamahora,izimvu zamanzi ezigugile zingaqala ukuvuza kakhulu, ikakhulukazi uma konakala indawo engaphezulu. Ngibonile ukuthi ukugcina ubuso be-seal buhlanzekile futhi bushelelezi kwenza umehluko omkhulu.
Kwezinye izimo, izimvu zamanzi zivumela umhwamuko omncane ukuba uphume—cishe 1 cc ngosuku. Lokhu kuphephile oketshezini oluningi. Kumakhemikhali ayingozi, imiklamo ekhethekile igcina ukuvuza cishe kuqanda.
Ngizizwa ngiziqhenya ngokwazi ukuthi izimvu zamanzi eziyimishini zivikela abantu kanye nemvelo ngokumisa ukuvuza ezimeni ezinzima.
Izinhlobo, Ukuqhathanisa, kanye Nezinzuzo Zezimpawu Zemishini
Izinhlobo Zezimpawu Zemishini Nezinhlelo Zokusebenza Ezijwayelekile
Ngibona izinhlobo eziningi zezimpawu zemishini emsebenzini wami. Uhlobo ngalunye luhambisana nomsebenzi okhethekile. Izigxivizo ze-Cartridge zifika zilungele ukufakwa, okwenza ukusetha kube lula. Ama-pusher seal asebenzisa iziphethu ukugcina ubuso be-seal buhlangene. Ukusetshenziswa kwama-non-pusher sealizifutho esikhundleni seziphethu. Ngivame ukusebenzisa ama-double seal oketshezini oluyingozi ngoba engeza ukuvikeleka okwengeziwe. Ukuhlukaniswa kwezimpawu kuyasiza lapho ngingakwazi ukuhlukanisa imishini. Ngikhetha uphawu olulungile ngokusekelwe kuketshezi, ingcindezi, nesivinini. Isibonelo, ngisebenzisa uphawu olulodwa kumaphampu amanzi ahlanzekile kanye nezimpawu ezimbili ezitshalweni zamakhemikhali.
Mechanical Seal vs. Ukupakisha nezinye izindlela
Lapho ngiqhathanisa uphawu olusetshenziswayo nokupakishwa kwezindlala, ngibona umehluko omkhulu. Ukupakisha kudinga ukuqiniswa njalo nokuvuza okwengeziwe. Ama-mechanical seal agcina ukuvuza kuphansi futhi konga amandla. Ngenze ithebula ukukhombisa umehluko omkhulu:
| Isici | Mechanical Seals | Ukupakisha kweGland |
|---|---|---|
| Isilinganiso sokuvuza | Iphansi ngokuphawulekayo;ukuvuza isilinganiso 1 | Okuphezulu kakhulu; ukuvuza isilinganiso 800 |
| Ukusetshenziswa kwamandla | Cishe ngo-50% ngaphansi kokupakisha | Ukusetshenziswa kwamandla okuphezulu |
| Izidingo Zokusebenza | Idinga ukugezwa ukuze iphole futhi ihlanzwe | Idinga ukunakekelwa njalo |
| Izinkinga zesondlo | Kuyazwela ukomisa ukugijima nokungaqondani kahle | Ijwayele ukuhuzuka nokuvuza |
Leli thebula liyangikhuthaza ukuthi ngikhethe inketho engcono kakhulu yomsebenzi ngamunye.
Izinzuzo Eziyinhloko Zokusebenzisa Izimpawu Zemishini
Ngizizwa ngiziqhenya lapho ngisebenzisa uphawu lukamshini ngoba luvikela imishini nendawo ezungezile. Yehlisa ukuvuza, yonga amandla, futhi yehlise nezindleko zokuyilungisa. Ngibona impilo yemishini ende kanye nokuphuka okumbalwa. Ngophawu olulungile, ngisiza iqembu lami ukuthi lisebenze ngokuphepha nangempumelelo.
Ithiphu:Ukukhetha uphawu olulungile kungaholela eminyakeni yokusebenza okungenazinkinga.
Ngiyethemba i-mechanical seal ukugcina okokusebenza kwami kusebenza kuqinile. Ngibona imiphumela yangempela: amaphampu ahlala iminyaka emithathu isikhathi eside, futhi ngonga kufika ku-50% ekunakekeleni. Nakhu engikuqaphelayo:
| Zuza | Umphumela Womhlaba Wangempela |
|---|---|
| Ukonga Amandla | Amandla angaphansi ngo-5-10% asetshenzisiwe |
| Izindleko Eziphansi | U-$500,000 ulondolozwe isayithi ngalinye |
FAQ
Yini okufanele ngiyenze uma uphawu lwami lukamshini luqala ukuvuza?
Ngihlale ngibheka ukungcola noma umonakalo kuqala. Ukuhlanza uphawu noma ukufaka izingxenye ezigugile ngokuvamile kuyixazulula inkinga.
Ithiphu:Ukuhlola okuvamile kugcina okokusebenza kwami kusebenza kuqinile.
Isici esiwumshini ngokuvamile sihlala isikhathi esingakanani?
Ngibona ama-seal amaningi ahlala unyaka owodwa kuya kwemihlanu. Ukunakekelwa okuhle nezinto ezifanele zingisiza ngifinyelele impilo ende ngangokunokwenzeka.
Ngingakwazi ukufaka uphawu lomshini ngedwa?
Ngikholwa ukuthi noma ngubani angafunda leli khono. Ngilandela imiyalelo isinyathelo ngesinyathelo.
- Ngisebenzisa amathuluzi afanele.
