Izigxivizo zemishini zingaxazulula izinkinga ezihlukahlukene zokuvala. Nazi ezimbalwa ezigqamisa ukuguquguquka kwezimpawu zemishini futhi zibonise ukuthi kungani zibalulekile emkhakheni wezimboni wanamuhla.
1. Izixube zeRibhoni Lempuphu Eyomile
Izinkinga ezimbalwa ziyavela uma usebenzisa izimpushana ezomile. Isizathu esiyinhloko ukuthi uma usebenzisa umshini wokuvala odinga isithambisi esimanzi, kungase kubangele ukuthi impushana ivaleke eduze kwendawo yokuvala. Lokhu kuvaleka kungaba yingozi ohlelweni lokuvala. Isixazululo siwukukhipha impushana nge-nitrogen noma umoya ocindezelwe. Ngale ndlela, impushana ngeke ingene, futhi ukuvala akufanele kube yinkinga.
Kungakhathaliseki ukuthi unquma ukusebenzisa i-nitrogen noma umoya ocindezelwe, qiniseka ukuthi ukugeleza komoya kuhlanzekile futhi kuthembekile. Uma ingcindezi iyancipha, khona-ke lokhu kungavumela impushana ukuthi ihlangane ne-packing-shaft interface, ehlula inhloso yokugeleza komoya.
Intuthuko entsha ekukhiqizeni ehlanganiswe kumagazini kaJanuwari 2019 wePumps & Systems idala izinto zegraphite ezenziwe nge-siliconized kusetshenziswa ukusabela komhwamuko wamakhemikhali okuguqula izindawo eziveziwe ze-electrographite zibe i-silicone carbide. Izindawo ezine-siliconized zimelana kakhulu nokuhuzuka kunezinsimbi, futhi le nqubo ivumela ukwenza okokusebenza kube ukulungiselelwa okuyinkimbinkimbi njengoba ukusabela kwamakhemikhali kungashintshi usayizi.
Amathiphu okufaka
Ukuze unciphise uthuli, sebenzisa i-valve yokukhipha enekhava evala uthuli ukuze uvikele isivalo se-gasket
Sebenzisa amasongo e-lantern ku-packing gland futhi ugcine inani elincane lokucindezela komoya phakathi nenqubo yokuhlanganisa ukuze uvimbele izinhlayiya ekufinyeleleni ibhokisi lokugxusha. Lokhu kuzophinde kuvikele i-shaft ekugqokeni.
2. Izindandatho Eziyisipele Ezintantayo ze-High-Pressure Rotary Seals
Izindandatho eziyisipele ngokuvamile zisetshenziswa ngokuhlanganiswa nezigxivizo eziyinhloko noma ama-O-rings ukusiza ama-O-rings amelane nemiphumela yokukhishwa. Indandatho eyisipele ilungele ukusetshenziswa ezinhlelweni ezijikelezayo ezinomfutho ophezulu, noma ezimeni lapho kukhona amagebe abalulekile wokukhipha.
Ngenxa yengcindezi ephezulu kusistimu, kunobungozi bokuthi i-shaft ingaqondani kahle noma ingcindezi ephezulu edala ukuthi izingxenye zikhubazekile. Nokho, ukusebenzisa indandatho eyisipele esintantayo ohlelweni olujikelezayo olunomfutho ophezulu kuyisixazululo esihle kakhulu ngoba kulandela ukunyakaza kwe-shaft ehlangothini, futhi izingxenye azikhubazeki ngesikhathi sokusetshenziswa.
Amathiphu okufaka
Enye yezinselelo eziyinhloko ezihlotshaniswa nezigxivizo zemishini kulezi zinhlelo zokucindezela okuphezulu ukuzuza ukucaciswa kwegebe elincane kakhulu lokukhipha ukuze kuncishiswe umonakalo owenziwe nge-extrusion. Uma igebe le-extrusion lilikhulu, umonakalo owenziwe uphawu ungase ube mkhulu ngokuhamba kwesikhathi.
Esinye isidingo ukugwema ukuthintana kwensimbi kuya kwensimbi endaweni ye-extrusion ebangelwa ukuchezuka. Ukuthintana okunjalo kungabangela ukungqubuzana okwanele okuvela ekushiseni ukuze kugcine kuntekenteke uphawu olusetshenziswayo futhi kulwenze lungakwazi ukumelana nokukhishwa.
3. Izinsimbi Ezicindezelwe Kabili ku-Latex
Ngokomlando, ingxenye eyinkinga kakhulu ye-latex seal esetshenziswayo ukuthi iyaqina lapho iboniswa ekushiseni noma ekungqubuzaneni. Lapho i-latex seal ichayeka ekushiseni, amanzi ayaphuma kwezinye izinhlayiya, okuphumela ekubeni yome. Lapho i-latex yokuvala ingena esikhaleni phakathi kobuso be-mechanical seal, ibhekana nokungqubuzana nokushelela. Lokhu kuholela ku-coagulation, okulimazayo ekubekweni uphawu.
Ukulungiswa okulula wukusebenzisa uphawu lomshini olucindezelwe kabili ngoba uketshezi oluvimbelayo lwenziwa ngaphakathi. Kodwa-ke, kunethuba lokuthi i-latex isengakwazi ukungena ezimpawu ngenxa yokuphazamiseka kwengcindezi. Indlela eqinisekile yokulungisa le nkinga ukusebenzisa i-double cartridge seal ene-throttle ukuze ulawule isiqondiso sokushaywa kwamanzi.
Amathiphu okufaka
Qinisekisa ukuthi iphampu yakho iqondaniswe kahle. I-shaft iyaphela, ukuchezuka phakathi nesiqalo esiqinile, noma izinhlobo zamapayipi zingaphonsa ukuqondanisa kwakho futhi kuzodala ingcindezi kuphawu.
Ngaso sonke isikhathi funda amadokhumenti ahambisana nezigxivizo zakho zemishini ukuze uqinisekise ukuthi uzifaka okokuqala ngendlela efanele; ngaphandle kwalokho, i-coagulation ingenzeka kalula futhi yonakalise inqubo yakho. Kulula kunalokho abanye abantu abalindele ukwenza amaphutha amancane angaphazamisa ukusebenza kophawu futhi abangele imiphumela engahlosiwe.
Ukulawula ifilimu ewuketshezi ehlangana nobuso be-seal kwandisa isikhathi sokuphila kwe-mechanical seal, futhi izimpawu ezicindezelwe kabili zinikeza lokho kulawula.
Ngaso sonke isikhathi faka uphawu lwakho olucindezelwe kabili ngesilawuli semvelo noma isistimu yokusekela ukuze wethule umgoqo woketshezi phakathi kwalezi zimpawu ezimbili. Uketshezi ngokuvamile luvela ethangini ukuze lugcobe izigxivizo ngohlelo lwamapayipi. Sebenzisa izinga kanye namamitha okucindezela ethangini ukuze lisebenze ngokuphephile futhi likwazi ukulibamba ngendlela efanele.
4. Izimpawu ezikhethekile ze-E-Axle zezimoto zikagesi
I-e-axle emotweni kagesi yenza imisebenzi ehlanganisiwe yenjini kanye nokudlulisa. Enye yezinselelo ekuvaleni lolu hlelo ukuthi ukuthuthwa kwezimoto zikagesi kugijima ngokuphindwe kasishiyagalombili kunezimoto ezihamba ngegesi, futhi ijubane lingase linyuke nakakhulu njengoba izimoto ezisebenza ngogesi zihamba phambili.
Izigxivizo zendabuko ezisetshenziselwa ama-eksisi anemikhawulo yokujikeleza cishe amafidi angu-100 ngomzuzwana. Lokho kulingisa kusho ukuthi izimoto zikagesi zikwazi ukuhamba amabanga amafushane ngamashaji eyodwa. Nokho, uphawu olusanda kuthuthukiswa olwenziwe nge-polytetrafluoroethylene (PTFE) lusingathe ngempumelelo ukuhlolwa komjikelezo womthwalo osheshisiwe wamahora angu-500 elingisa izimo zokushayela zomhlaba wangempela futhi lazuza isivinini sokujikeleza samafidi angu-130 ngomzuzwana. Izigxivizo zafakwa emahoreni angama-5,000 okuhlolwa kokubekezela, futhi.
Ukuhlolwa ngokucophelela kwezimpawu ngemva kokuhlolwa kwabonisa ukuthi kwakungekho ukuvuza noma ukuguga ku-shaft noma udebe oluvalayo. Ngaphezu kwalokho, ukugqoka endaweni egijimayo kwakungabonakali.
Amathiphu okufaka
Izigxivizo ezishiwo lapha zisesigabeni sokuhlola futhi azikakalungeli ukusatshalaliswa kabanzi. Kodwa-ke, ukuhlangana okuqondile kwemoto kanye no-gearbox kuveza izinselelo ezihlobene nezimpawu zemishini yazo zonke izimoto zikagesi.
Ngokukhethekile, injini kufanele ihlale yomile ngenkathi i-gearbox ihlala igcotshiwe. Lezo zimo zenza kube semqoka ukuthola uphawu oluthembekile. Ukwengeza, abafaki kufanele bahlose ukukhetha uphawu oluvumela i-e-axle ukuthi ihambe ngokuzungezisa okudlula ukuzungezisa okungu-130 ngomzuzu - okuthandwa yimboni yamanje - kuyilapho kunciphisa ukungqubuzana.
Ama-Mechanical Seals: Ibalulekile ekusebenzeni Okungaguquguquki
Ukubuka konke lapha kukhombisa ukuthi ukukhetha isigxivizo esilungile senhloso sinomthelela ngqo emiphumeleni. Ngaphezu kwalokho, ukujwayelana nezinqubo ezihamba phambili zokufaka kusiza abantu bagweme izingibe.
