Izivalo ezithintana nomshini zithembele kungqimba loketshezi oluncane olugcinwe phakathi kobuso bazo obujikelezayo nobungaguquki. Lapho le filimu yoketshezi inyamalala, uphawu luyoma. Ngenkathi lesi sihloko sigxile ezivalo ezithintana noketshezi ezijwayelekile kumaphampu e-centrifugal avundlile, anesigaba esisodwa, kubalulekile ukuqaphela ukuthi amaphampu aqondile, imiklamo yokugeleza okuxubile, kanye nezivalo zensimbi ezishayayo zibonisa ukuziphatha okuhlukile kokugijima okomile kanye nokubekezelelana. Izixazululo eziklanywe ngendlela—njengezivalo zegesi ezomile, izivalo ezihlukanisiwe, noma ubuso obukhethekile bokuzigcoba—nazo zinamakhono ahlukene okugijima okomile.
Ubuqotho besistimu buncike kakhulu kule filimu yoketshezi, enikeza ukuthambisa okubalulekile kwe-hydrodynamic kanye nokupholisa kwendawo. Ngaphandle kwayo, uphawu lubhekene nokucindezeleka okukhulu kwe-tribological futhi lonakala ngokushesha. Ukuqonda indlela esebenza ngayo, umthelela wezohwebo, kanye nezimbangela eziyinhloko zokugijima okomile kusiza onjiniyela bokuthembeka ukuthi bathuthukise isikhathi esimaphakathi phakathi kokwehluleka (i-MTBF) futhi banciphise izindleko zomjikelezo wokuphila.
Umthelela wezentengiselwano wokuhamba komoya owomile
Umthelela wezezimali wokusebenza okomile udlulela ngale kwentengo yesivalo sokufaka esikhundleni. Izindleko zokulungisa eziqondile zesilinganisoukwehluleka kophawu lwephampu ye-centrifugalngokuvamile isukela ku-$3,000 kuya ku-$10,000 uma kubhekwa umsebenzi, izingxenye ezithathelwanayo, kanye nezinqubo zokuhlanza. Kodwa-ke, lesi sibalo siyahlukahluka kakhulu kuye ngobukhulu besivalo, imboni, indawo, nokuthi ngabe iphampu iyimodeli ejwayelekile ye-ANSI, i-API esindayo, noma eyenziwe ngokwezifiso.
Isikhathi sokungasebenzi esingahleliwe sibiza kakhulu. Isibonelo, ukwehluleka kokusebenzisa ipompo yokuphakelwa kwebhoyila ebalulekile kungaphoqa isitshalo sikagesi ukuthi siphazamise iyunithi, okuholela ezinkulungwaneni zamaRandi ngehora ekukhiqizeni okulahlekile. Ukwehluleka okukhulu nakho kubeka engcupheni izinhlawulo zemvelo, ukulungiswa kwezinto eziyingozi, kanye nomonakalo wesibili wemishini, okuphindaphinda izindleko zesigameko esisodwa.
Incazelo yokusebenza okomile
Ukugeleza okomile kwenzeka lapho ifilimu yoketshezi lokuthambisa—ngokuvamile ubukhulu obuyi-1 kuya ku-3 microns—inyamalala ngokuphelele esibonakalayo sesivalo, iphoqa ubuso obucwebezelisiwe kakhulu ukuba bube buthintana ngqo, obungagcotshwanga.
Nakuba abakhiqizi beklama izivalo zemishini ukuze baphathe ukugcotshwa kwemingcele okufushane ngesikhathi sokuqalisa nokuvala, ukusebenza okomile okuqhubekayo kwephula le mingcele yokuklama. Ngaphandle kwe-medium yoketshezi yokususa ukushisa okukhulu okubangelwa yi-shaft ejikelezayo, isivalo siyahluleka ngokushesha ngokusebenzisa umonakalo wokushisa nowomshini ochazwe ezigabeni ezilandelayo.
Izimbangela ezivamile ezinhlelweni zamaphampu
Ukuphazamiseka kwe-hydraulic kanye namaphutha okusebenza kubangela izehlakalo eziningi zokungasebenzi kahle. Abaqhubi bavame ukubangela ukusebenza okomile ngokuqala ipompo ngaphandle kokukhipha umoya kahle ekhasejini, okushiya umoya noma umusi uvaleleke ebhokisini lokugcwala. Ukusebenzisa ipompo nge-valve yokumunca evaliwe nakho kuqeda ngokuphelele uketshezi oluphuma ekamelweni lokuvalela.
Ezinye izinto ezivame ukubangela lokhu kuhlanganisa ikhanda lokumunca elihlanzekile nelingenawo amandla (NPSha) okubangela ukucasuka okukhulu, ukuvuza ethangini lokumunca, noma ukusebenzisa ipompo kude kakhulu nendawo yayo yokusebenza kahle (BEP).

Kwenzekani Ngaphakathi Kwesivalo Ngesikhathi Sokugijima Komile
Uma uphawu lulahlekelwa ifilimu yalo yoketshezi, lungena emjikelezweni obhubhisayo wokungqubuzana, ukushisa, kanye nokuguquka kwezinto. Ngenxa yokuthi ubuso bophawu buhlangene kakhulu, ukuthintana okuqondile kudala amandla amakhulu okusika. Amandla okushisa avelayo aphuma ngaphandle, onakalise izingxenye zokulawula zesibili kanye nezindlela zokushayela.
Ukuwa kwefilimu yokugcoba
Ngaphansi kwezimo ezijwayelekile, ifilimu yoketshezi igcina i-coefficient of friction (COF) iphansi kakhulu. Uma le filimu iwa, uhlelo lokusebenza lushintsha ngokushesha lube yi-dry friction, okwenza i-COF ikhuphuke kakhulu.
Lokhu kwanda okukhulu kokumelana nokungqubuzana kudinga i-torque eningi kakhulu kusuka kumoto ukuze kugcinwe ukujikeleza komgodi. Ngaphandle kwefilimu yoketshezi, ukungabi namandla okubonakalayo kwesivalo kubhekene nokushintshwa okubandayo nokuqhekeka, kususe ngokushesha amaphrofayili akhethekile obuso avame ukunikeza ukuphakama kwe-hydrodynamic.
Ukushisa okuguquguqukayo kanye nomonakalo wobuso
Ukungqubuzana okuphezulu ngokushesha kudala ukushisa okukhulu kwendawo. Ngaphandle koketshezi lokupholisa isixhumi esibonakalayo, amazinga okushisa angafinyelela amazinga alimazayo—ngokuvamile adlula u-300°C kuya ku-500°C kuma-silicon carbide kanye ne-carbon pairings ngesivinini esijwayelekile semoto—ngaphakathi kwemizuzwana kuya kwemizuzu, kuye ngezimo ze-pressure-velocity (PV).
Lokhu kushisa okukhulu kubangela izindlela ezahlukene zokwehluleka ngokusekelwe ezintweni zobuso. Izinto eziqinile njenge-silicon carbide noma i-tungsten carbide zithola ukushaqeka kokushisa, zanda ngokungalingani futhi zakha ama-radial micro-fractures abizwa ngokuthi “ukuhlola ukushisa.” Izinto ezithambile, njenge-resin-impregnated carbon, i-blister njengoba izihlanganisi zazo zangaphakathi zanda futhi ziqhuma endaweni yokuvala, zibhubhisa i-micro-flatness edingekayo.
Imiphumela kuma-elastomer, izipringi, kanye nezingxenye zokushayela
Njengoba ukushisa kuphuma ebusweni besivalo, kuyawohloka izingxenye zesibili. Ama-O-ring e-Elastomeric ayawohloka ngokusekelwe emikhawulweni yawo ethile yokushisa; isibonelo, i-FKM (Viton) ejwayelekile ivame ukuqina futhi ithathe isethi ehlala njalo ngaphezu kuka-200°C, kuyilapho i-PTFE yonakala futhi iphuma ngaphezu kuka-260°C.
Ngale kwama-elastomer, ukungqubuzana okomile kudlulisela i-torque enamandla kuma-pins okulwa nokujikeleza kwesivalo kanye nezindlela zokushayela. Ama-drive pins angaqhekeka, noma i-seal sleeve ingajikeleza ku-shaft futhi ibangele ukugabha okukhulu. Izipringi ze-coil zensimbi kanye nama-bellows nawo alahlekelwa yisimo sawo sokushisa nokucindezeleka ngenxa yokushisa, ehluleka ukugcina amandla okuvala adingekayo ngisho noma opharetha bebuyisela uketshezi kamuva.
Indlela Umonakalo Owomile Ohlukahluka Ngayo Ngokwezimo Zesevisi
Imicimbi yokusebenza okomile iqhubeka ngamazinga ahlukene futhi iveza amaphrofayili omonakalo ahlukene. Ubunzima buxhomeke kakhulu ezimweni zesevisi ngesikhathi ipompo ilahlekelwa ifilimu yayo yoketshezi.
Izakhiwo zoketshezi, isivinini sokujikeleza, kanye nezinto zobuso konke kunquma ukuthi uphawu luyasinda yini okwesikhashana noma luhluleka ngendlela eyinhlekelele.
Ubunzima bomonakalo ngesikhathi sokuvezwa
Ubude bokuvezwa yisona sici esibaluleke kakhulu ekusindeni kwe-seal. Ukulahlekelwa okwesikhashana kokumunca okuhlala imizuzwana embalwa kuphela kungabangela ukugoba okuncane okuziphilisayo uma uketshezi lubuya.
Kodwa-ke, ukuhamba okomile okuqhubekayo kuba yingozi ngokushesha kuma-seal ajwayelekile angawodwa. Njengoba ukuvezwa kuqhubeka, ukwanda kokushisa kuphazamisa unomphela ubuso be-seal futhi kuvula indlela yokuvuza. Ezisetshenzisweni zesivinini esikhulu, ukwehluleka okubi kakhulu—njengobuso obuqinile obuphukile noma ama-O-rings ancibilikisiwe—kwenzeka ngokushesha okukhulu ngenxa yokuqongelela okusheshayo kokushisa okungqubuzanayo.
Umehluko phakathi kwamanzi, amakhemikhali, ama-hydrocarbon, kanye nama-slurry
Uketshezi olupompiwe lulawula imiphumela yesibili yesenzakalo sokuphuma komoya. Lapho upompa amanzi, ukwehla kwengcindezi noma ukuphakama kwezinga lokushisa kubangela ukuthi ifilimu yoketshezi esele ikhanye ibe umusi. Lokhu kwandiswa komthamo okunamandla kubhidliza ngamandla ubuso besivalo, okubangela ukushayisana nokuqhekeka komphetho.
Ezinkonzweni ze-hydrocarbon, ukushisa kuyawaphula ngokushisa ama-residue oketshezi, kubeke ungqimba oluqinile nolunamandla lwe-coked carbon ebusweni. Ekusetshenzisweni kwe-slurry, isithwali soketshezi siyahwamuka, sibhaka izinto eziqinile ezilenga ngqo ebusweni be-seal kanye neziphethu. Lokhu kukhiya izingxenye ezinamandla futhi kubhubhise izindawo ezigobile.
