Isingeniso
Ukukhetha uphawu lomgodi wepompo kuthinta okungaphezu kokuvuza emgodleni. Ukukhetha okulungile kuthinta isikhathi sokusebenza kwemishini, imvamisa yokulungisa, ukusetshenziswa kwamandla, ukuphepha, kanye nokuhambisana nezindinganiso zokukhishwa komoya. Ngenxa yokuthi ukusebenza kophawu kuncike ekucindezelweni kokusebenza, izinga lokushisa, izakhiwo zoketshezi, isivinini somgodi, kanye nomklamo wepompo, inketho efanelekile ohlelweni olulodwa ingase yehluleke ngokushesha kolunye. Lesi sihloko sichaza izici ezibalulekile eziqondisa ukukhethwa kophawu, siqhathanisa izinhlobo zophawu ezivamile nezinto zokwakha, futhi sibonisa ukuthi singazifanisa kanjani nezimo zokusebenza zangempela. Ekugcineni, abafundi bazoba nohlaka olusebenzayo lokukhetha uphawu oluthuthukisa ukuthembeka futhi lwehlise izindleko zokusebenza eziphelele.
Kungani Kubalulekile Ukukhetha Iphampu Efanele Yokumboza Umgodi
Ekwakhiweni kwemishini ejikelezayo,uphawu lomgodi wepompoimelela ukuzivikela okuyinhloko ekulahlekelweni uketshezi, ukungcoliswa komoya, kanye nokwehluleka okukhulu kwemishini. Naphezu komthelela wayo omncane ngokomzimba ngaphakathi kwephampu ye-centrifugal noma ye-positive displacement, uphawu lwe-shaft luyimbangela yephesenti eliphezulu kakhulu lokungasebenzi kwephampu. Izifundo zokuthembeka embonini zibonisa njalo ukuthi ukwehluleka kophawu kubalwa u-65% kuya ku-70% wazo zonke izindlela zokulungisa iphampu.
Ukukhetha indlela efanele yokuvala akuyona nje indaba yokuhambisana kwehadiwe; kuyisinqumo sobunjiniyela esiyinkimbinkimbi esinquma ngqo umjikelezo wokuphila kwempahla. Ukucushwa kwesivalo okwenziwe kahle kukhulisa i-Mean Time Between Failures (MTBF), kuvikela ukuhambisana nemvelo, futhi kunciphisa izindleko zokusebenza eziqhubekayo ezihlobene nokulahlekelwa komkhiqizo kanye nomsebenzi wokulungisa.
Umthelela ekusebenzeni kwesikhathi kanye nokuvuza
Ubudlelwano obuqondile phakathi kokukhethwa kwesivalo kanye nesikhathi sokusebenza kwesikhungo kulinganiswa nge-MTBF kanye namazinga okuvuza kwevolumu. Isivalo esenziwe kahle kakhulu esisebenza ngaphansi kwezimo ezifanele singandisa i-MTBF yephampu kusukela ekuqaleni kwezinyanga eziyi-12 kuya ezinyangeni ezingaphezu kwezingu-36. Ngakolunye uhlangothi, isivalo esisetshenziswe kabi sizobhekana nokuguguleka kobuso okusheshayo, ukuphazamiseka kokushisa, noma ukuwohloka kwe-elastomer, okuphoqa ukuvalwa ngaphambi kwesikhathi.
Imithetho yesimanje yokukhishwa komoya idinga ukulawulwa okuqinile kokuvuza. Isibonelo,izimpawu zomshiniEklanyelwe ngokwezindinganiso ze-API 682 ngokuvamile yakhelwe ukuvimbela ukukhishwa kwe-volatile organic compound (VOC) kube ngaphansi kwezingxenye ezingama-500 ngesigidi (ppm), kanti amazinga aphezulu okuvuza koketshezi avunyelwe avame ukuvalwa ku-5.6 amagremu ngehora ekusetshenzisweni okujwayelekile kwe-hydrocarbon. Ukugcina lokhu kubekezelelana kokuvuza okuncane kakhulu yikho okugcina izitshalo zokucubungula eziqhubekayo zisebenza ngaphandle kokuphazamiseka komthetho.
Imiphumela yokukhetha uphawu okungalungile
Ukwehluleka ukucacisa isivalo sephampu esifanele kubangela uchungechunge lwemiphumela emibi. Umthelela osheshayo kakhulu ungowezezimali: emisebenzini ye-petrochemical enamandla aphezulu noma yokucwenga, isikhathi sokungasebenzi kwephampu esingahleliwe singadala izindleko ezisukela ku-$10,000 kuya ku-$50,000 ngosuku ekukhiqizweni okulahlekile kuphela.
Ngaphandle kwemali engenayo elahlekile, ukukhetha okungalungile kubeka engcupheni ukuphepha. I-seal engakwazi ukuphatha ukuphakama kwengcindezi okungalindelekile noma ama-transients okushisa okuphezulu ingase ibhekane nokuqhuma kobuso okubi, ikhiphe uketshezi oluyingozi, oluvuthayo, noma olunobuthi emoyeni. Ngaphezu kwalokho, ukukhetha okungalungile kwe-seal kuvame ukuholela ekulimaleni kwemishini yesibili, njengokuqhekeka okukhulu kwe-shaft, ukungcola kwamabhere, kanye nokwehluleka kwenjini ngenxa yokungena koketshezi, okuphindaphinda izindleko zokulungisa eziyisisekelo ngesilinganiso samathathu kuya kwayisihlanu.
Izisekelo Zophawu Lomshafu Wephampu Nezinhlobo Eziyinhloko
Izivalo zombhobho wepompo yezimboni zisebenza ngesimiso sokulawula ukuvuleka phakathi kombhobho ojikelezayo kanye nebhokisi lepompo elingaguquki. Nakuba umgomo oyisisekelo uhlala ungaguquki, indlela yomshini iyahlukahluka kakhulu ngokusekelwe ekufutheni koketshezi, izinga lokuvuza elidingekayo, kanye nesabelomali sokulungisa esitholakalayo. Izigaba ezimbili ezivelele ukupakisha kokucindezela kwendabuko kanye nezivalo zomshini eziqondile.
Ukupakisha vs izivalo zemishini
Ukupakisha ngokucindezela, okwakwaziwa ngokomlando ngokuthi ukupakisha nge-gland, kusebenzisa izinto ezilukiwe (njenge-PTFE, i-graphite, noma i-aramid) ezicindezelwe nxazonke ze-shaft ukuze kuvinjelwe ukugeleza koketshezi. Kudinga ukuvuza okuhlosiwe, okuqhubekayo—ngokuvamile cishe amaconsi angu-40 kuya kwangu-60 ngomzuzu—ukugcoba nokupholisa i-shaft. Nakuba ukupakisha kunikeza izindleko zokuthenga eziphansi futhi kungapakishwa kabusha ngaphandle kokuhlakaza ipompo ngokuphelele, kusebenzisa amandla okungqubuzana aphindwe kasithupha kunezinye izindlela.
Izivalo zomshini zisebenzisa ubuso obubili obuyisicaba kakhulu bokuhlangana (obunye bujikeleza, obunye bunganyakazi) obucindezelwe ndawonye ngenxa yokucindezeleka kwentwasahlobo kanye nokucindezela koketshezi. Ifilimu yoketshezi oluncane kakhulu, ngokuvamile engaphansi kwe-1 micron ubukhulu, ihlukanisa ubuso, okuholela ekuvuza okubonakalayo okucishe kube yi-zero. Nakuba ukutshalwa kwezimali kokuqala kuphakeme, izivalo zomshini ziqeda ukushaqeka komgodi futhi zinciphisa kakhulu ukulahleka komkhiqizo.
| Isici | Ukupakisha Kokucindezela | Uphawu Lomshini |
|---|---|---|
| Izinga Lokuvuza Elibonakalayo | Amaconsi angu-40 – 60 ngomzuzu | < 5.6 g/ihora (cishe u-zero) |
| Ukulahlekelwa Amandla Okungqubuzana | Okuphezulu (ukuhudula okuqhubekayo) | Iphansi (ifilimu yoketshezi igcotshwe) |
| Izindleko Zokuqala Zokuthenga | Okuphansi ($50 – $200) | Okuphezulu ($500 – $5,000+) |
| Ukugqokwa Kweshafti/Imikhono | Okuphezulu (ukukhathazeka kuyinto ejwayelekile) | Akukho (ukuguguleka kuhlukaniswe ebusweni) |
Izivalo zekhatriji ezilodwa, ezimbili, kanye nezimbozo zekhatriji
Izivalo zemishini zihlukaniswa ngokwendlela ezihlelwe ngayo. Izivalo ezilodwa zakhiwe yibhangqa elilodwa lobuso bokuhlangana futhi ngokuvamile zifanelekela uketshezi olungeyona ingozi olufinyelela ku-300 psi. Zithembele ngokuphelele oketshezini olupompiwe ukuze zigcotshwe.
Izivalo eziphindwe kabili zisebenzisa ubuso obubili kanye nohlelo lokuvimba noma lokuvimba. Elungiselelweni lokuvimba okuphindwe kabili elicindezelwe, uketshezi lokuvimba lugcinwa lunomfutho ongu-10% kuya ku-15% kunomfutho webhokisi lokugcwalisa lephampu, okuqinisekisa ukuthi uma uphawu lwangaphakathi luhluleka, uketshezi lokuvimba luvuza enqubweni, kunokuba uketshezi lwenqubo oluyingozi luvuze emkhathini.
Izimpawu zekhatrijiamayunithi ahlanganiswe ngaphambilini aqukethe ubuso besivalo, ipuleti le-gland, i-sleeve, kanye nama-elastomer ashukumisayo ephaketheni elilodwa. Ngokususa isidingo sokusetha ngesandla ukucindezela kwentwasahlobo yesivalo (ubude bokusebenza) kushaft, izivalo ze-cartridge zinciphisa amaphutha okufakwa ngo-40% olinganiselwa futhi zisheshise kakhulu izikhathi zokulungisa.
Ifaneleka kakhulu uketshezi oluhlanzekile, oluhlabayo, noma oluyingozi
Ukuqondanisa uhlobo lwesivalo nesimo soketshezi kuyitshe lesisekelo sokuthembeka. Koketshezi oluhlanzekile nolungenangozi njengamanzi okupholisa noma izinyibilikisi ezilula, isivalo sekhatriji esisodwa sinikeza ukusebenza okungabizi kakhulu.
Ukusetshenziswa okunolaka, njengemigodi noma amanzi angcolile aqukethe amazinga aphezulu e-silica, kudinga izixazululo eziqinile. Ukuhlanganiswa kobuso obuqinile (isb., i-Silicon Carbide ngokumelene ne-Silicon Carbide) kuyimpoqo, kuvame ukubhangqwa ne-flush yangaphandle ehlanzekile (i-API Plan 32) ukugcina izinhlayiya kude negebe lokuvala elibalulekile.
Kuketshezi oluyingozi kakhulu, olunobuthi, noma olubulalayo, izivalo ezicindezelwe kabili (ezisekelwa yi-API Plan 53A, 53B, noma izinhlelo zoketshezi oluvimbelayo ezingama-54) ziyadingeka ngokomthetho nangokusebenza. Lokhu kulungiswa kuqinisekisa ukuthi akukho ukukhishwa kwenqubo emoyeni, okuyisidingo esiqinile ngaphansi kwe-EPA kanye neziqondiso zemvelo zomhlaba wonke.
Izimo Zokusebenza kanye Nemininingwane Eqhuba Ukukhetha
Ukwakha uphawu lomshini wokupompa kudinga ukuhlola izimo eziqondile zomzimba nezokushisa zokusetshenziswa kokupompa. Isilinganiso esibanzi esisetshenziselwa ukunquma ukusebenza kophawu lomshini yinani le-PV (Pressure-Velocity), elibala umthwalo ebusweni bophawu kuhlanganiswe nejubane lokushelela. Ukudlula umkhawulo we-PV womenzi kuqinisekisa ukuhwamuka kwangaphambi kwesikhathi kwefilimu yoketshezi kanye nokubhujiswa kobuso okusheshayo.
Ingcindezi, izinga lokushisa, isivinini, kanye nezakhiwo zoketshezi
Imikhawulo yokucindezela ilawula ubuqotho besakhiwo sesivalo. Izivalo zemishini ezingalingani ezijwayelekile zivame ukukhawulelwa ekucindezelweni kwebhokisi lokugcwala elingu-150 psi, kanti izivalo ezilinganisiwe zingaphatha ukucindezeleka okufika ku-400 psi, kanti izivalo ezenziwe ngokwezifiso eziklanywe kahle zingamelana nokufinyelela ku-3,000 psi ekusetshenzisweni kwamapayipi. Amaphrofayili okushisa alawula ukubekezelelana kokushisa; izivalo kumele zisebenze ngokuphepha kuzo zonke izinhlobo eziningi, ngokuvamile kusukela ku--40°C ezinkonzweni ze-cryogenic kuya ngaphezu kuka-400°C ezindaweni zokuhlanza uwoyela oshisayo.
Ijubane lokujikeleza kwe-shaft lithonya ngqo amandla e-centrifugal kanye nokukhiqizwa kokushisa okungqubuzanayo ebusweni be-seal. Iningi le-seal ezijwayelekile lilinganiselwe isivinini sobuso esifinyelela kumamitha angu-25 ngomzuzwana (m/s). Ngaphezu kwalokho, izakhiwo zoketshezi ezifana ne-viscosity zithinta kakhulu ukuphakama kwe-hydrodynamic kwe-seal. Uketshezi olune-viscosity ephezulu (ngaphezu kwama-centipoise angu-3,000) lwandisa ukucindezeleka kwe-shear ezingxenyeni ezijikelezayo, okuvame ukudinga ama-drive pins akhethekile noma izindlela zokudlulisa i-torque eziqinile ukuvimbela uphawu ukuthi lungaphambuki.
Ukuhambisana kwezinto ezibonakalayo zobuso, ama-elastomer, nezingxenye zensimbi
Ukukhethwa kwezinto kuyinqubo enzima yokufanisa izinsimbi kanye nama-elastomer nobukhali bamakhemikhali boketshezi lwenqubo. Ngobuso bokuqala bokuvala, onjiniyela balinganisela ubulukhuni, ukuhanjiswa kokushisa, kanye nokungasebenzi kahle kwamakhemikhali.
Ama-Elastomer (ama-O-rings) nawo abaluleke kakhulu. I-Nitrile ejwayelekile (i-NBR) inqunyelwe ku-90°C kanye nemisebenzi eyisisekelo yamanzi/amafutha. Ama-Fluoroelastomer afana ne-FKM (Viton) andisa imikhawulo yokushisa ifike ku-204°C futhi anikeza ukumelana okubanzi kwamakhemikhali, kuyilapho ama-Perfluoroelastomer afana ne-FFKM (Kalrez) agcinelwe amakhemikhali aphezulu kanye namazinga okushisa afinyelela ku-327°C. Izingxenye zensimbi ezakhiwe—izipringi, ama-gland, kanye nemikhono—zivamise ukwenziwa ngomshini kusuka ku-316 Stainless Steel, yize izindawo ezingcolisa kakhulu zingadinga i-Alloy 20, i-Hastelloy C-276, noma i-Titanium.
| Izinto Zobuso | Ubulukhuni (I-Knoop) | Ukushisa Okuphezulu (W/mK) | Iphrofayela Yesicelo Esiyinhloko |
|---|---|---|---|
| I-Carbon Graphite | 100 – 150 | 10 – 15 | Amanzi ahlanzekile, izidingo eziphansi zokungqubuzana |
| I-Silicon Carbide (i-SiC) | 2,500 – 2,800 | 120 – 130 | Izinto zokubhula, uketshezi olushisa kakhulu |
| I-Tungsten Carbide (WC) | 1,800 – 2,200 | 80 – 100 | Ukushaqeka okukhulu ngokomzimba, okunomthelela omkhulu |
| I-Alumina Ceramic | 2,000 | 20 – 30 | Amakhemikhali agqwala kakhulu |
Uhlu lokuhlola lokukhetha uphawu
