Umhlahlandlela wokugcina wokuthwala ukuhlaziywa kokudlidliza nenani le-GE | Shangdong yueheng

Njengonjiniyela we-MRO noma unjiniyela wokuthengwa kwempahla, uyaqonda ukuthi impilo yemishini yakho iyimpilo yokusebenza kwakho. Isikhathi sokuphumula esingahleliwe singaphezu kokuphazamiseka; Kuyinto eqondile emgqeni wakho ongezansi. Le ndatshana i-dive yakho ejulile ibe yinye yamathuluzi anamandla kakhulu ekunakekelweni kokuqagela: Ukuhlaziywa kokudlidliza, ngokugxila okuthile kubalulekile inani. Sizohlola ukuthi yini lesi silinganiso, ukuthi ungayihumusha kanjani, nokuthi ungakubeka kanjani ukuvikela ukwehluleka kwemishini yakho, futhi uqinisekise ukuthembeka okungaguquki inkampani yakho incike kukho. E-VPK ephethe, asizivele nje zenziwe ama-bearings; Sinikeza ubuchwepheshe bokusiza ozakwethu baphumelele.

Kuyini ukuhlaziywa kokudlidliza futhi kungani kubalulekile?

Emgogodleni wayo, Ukuhlaziywa kokudlidliza Ingabe inqubo yokulinganisa amasiginali okudlidliza emshinini, ukucubungula leyo datha, kanye nokusebenzisa imininingwane ukunquma impilo yomshini nezinto zayo. Cabanga ngakho njengodokotela usebenzisa i-stethoscope ukulalela ukushaya kwenhliziyo kwesiguli. Yonke imishini ejikelezayo, kusuka ebhokisini lamagiya wezimboni liye emotweni encane kagesi, ikhiqiza isiginesha eyingqayizivele "ye-vibration" lapho isesimweni esihle sokusebenza. Lapho ingxenye efana ne -buzile Kuqala ukwehluleka, kwethula ukunyakaza okusha, okuhlukile kuleso siginesha.

Ukuze umphathi onjengawe, uRichard, lokhu akuyona isayensi engabonakali. Kuyindlela esebenzayo, engahlaseli yokubheka ngaphakathi kwemishini yakho ngenkathi iyasebenza. Ngokusungula isisekelo sokudlidliza okujwayelekile bese kubhekwa ushintsho, unga:

• Thola amaphutha kusenesikhathi: Khomba izingqinamba ezinjengokuthela ukugqokwa, ukuphakamiseka, noma ukungalingani isikhathi eside ngaphambi kokuba kube ukwehluleka okubucayi.
• Vikela ukulimala okuyinhlekelele: Ukwehluleka -buzile Ungabhubhisa imisele, izindlu nezinye izingxenye ezibizayo uma kushiywe kungalawulwa.
• Hlela ukulungiswa ngokuphumelelayo: Esikhundleni sokuphendula ekwakhekeni, ungahlela ukulungiswa ngesikhathi sokuhlelwa okuhleliwe, ukonga izindleko ezinkulu.
• Khulisa ukuphepha: Ukuvimbela ukwehluleka kwemishini okungalindelekile kuvikela abasebenzi bakho kanye nesikhungo sakho.

Ukwethenjwa kwawo wonke ama-mehendi wohlelo kuncike empilweni yezingxenye zawo ezincane kakhulu. Iphutha elilodwa -buzile ingamisa lonke umugqa wokukhiqiza. Kungakho ukuqonda idatha kusuka ekuhlaziyweni kokudlidliza kuyitshe lesisekelo sokulungiswa kwezimboni kwanamuhla.

Yini ngempela i-ge inani lokuthola ukudlidliza?

Manje, ake siqonde. Ungahle ubone izilinganiso ezahlukahlukene embikweni wokudlidliza: velocity, ukuthuka, ukushesha. Kepha omunye waba namandla kakhulu -buzile Ukuxilonga yilona inani, eyaziwa nangokuthi "ukusheshisa okumbozwayo" noma "ukumboza okumboze." Le yindlela ekhethekile yokulinganisa iphayona yizinkampani ezifana Skf.

Ngakho-ke, kuyini? Cabanga ngephutha elincanyana emncintiswaneni wokuthwala. Njalo lapho into egoqayo idlula kuleso sine, idala umthelela omncane, ovame kakhulu, noma "chofoza." Emvelweni enomsindo wezimboni, lokhu kuchofozwa okuncane kukhishwa ngokuvezwa okujwayelekile komshini, okuphansi okuphansi (njengokuhlambalaza nokuqhuma). Le khasi gearlika Inqubo isebenza njengesihlungi esikhethekile. Akunaki umsindo omkhulu wesemuva, ophansi kakhulu futhi uhlukanisa amandla "umthelela" we-frequency frequency " La mandla asetshenziselwe ukukhiqiza inani elilodwa, elilula: inani.

Ukukhuphuka inani kuvame ukuba yisibonakaliso sokuqala sesexwayiso sokuthi a -buzile isenkingeni. Kungathola amaphutha amancane ama-Microscopic ukuthi izilinganiso ezijwayelekile zokudlidliza zingaphuthelwa, zikunikeze isixwayiso sokuqala sokwehluleka okuzayo. Lokhu yilolu uhlobo lwedatha ethembekile, yokuxwayisa kusenesikhathi ukuthi umphathi osuselwa kumininingwane edinga ukuvimbela isimanga esibizayo.

Ngabe kuthathwa kanjani isilinganiso sokusheshisa kwe-ge emvelweni?

Ukuqoqa okunembile gearlika Idatha iyinqubo eqondile, kepha idinga amathuluzi namasu afanele. Ithuluzi eliyinhloko yi azvuzi, inzwa (imvamisa kazibuthe) ebekwe ngqo ezindlini ezithwala umshini. Leli azvuzi iguqula ukunyakaza okwenziwe ngomshini kokudlidliza kube yisiginali kagesi.

Lesi siginali bese sondliwa kumqoqi wedatha, njenge I-Skf Microal I-Analizer. Nakhu okwenziwe lula okwenzeka ngaphakathi komqoqi ukukhiqiza i gearlika Inani:

1. Ukutholwa kwedatha: Le khasi azvuzi uthatha uhla oluphelele lokudlidliza kusuka ku -buzile.
2. Ukuhlunga okuphezulu okuphezulu: Uhlelo lusebenzisa isihlungi sokususa wonke ama-vibrations aphansi aphansi ahambisana nokusebenza okujwayelekile komshini (njengokujikeleza kwe-shaft kanye nokungalingani).
3. Ukumboza (ukugcotshwa): Isiginali esele imvamisa ephezulu, equkethe imiphumela evela kwiphutha elinemvume, iyacutshungulwa. "Imvilovo" yalesi siginali iyadalwa, empeleni elandelwa yi-Peak Amplitude yemithelela.
4. Ukuhlunga okuphezulu kwe-Low-Pass & FFT: Lesi siginali esimbozwayo siphinde sahlungwa futhi futhi sihlaziywe kusetshenziswa i-Four Fourier Transform (FFT) ukudala i-spectrum. Lesi sibonelelo sibonisa izinga lapho imithelela yenzeka khona.
5. Ukufundwa kwe-GE: Amandla aphelele ngaphakathi kobubanzi obuthile bokuvama kwalesi sibonelelo sokugcina kubalwa ukukhiqiza owokugcina gearlika inani.

Lesi silinganiso sinikeza inombolo ecacile, ethe xaxa. Ngokuthatha isikhathi esithile ukufunda kusuka endaweni efanayo emshinini, ungabheka -buzile Isimo ngokuhamba kwesikhathi futhi wenze ngaphambi kwenkinga ukukhuphuka.

Yini imvamisa yesimo sokuthwala okuhlulekayo?

Ngenkathi iyonke gearlika Inani likunikeza inkomba enkulu yobulukhuni benkinga, gearlika I-Spectrum ihlinzeka ngemininingwane yokuxilonga ukukhomba indawo ngqo yephutha. Into egoqayo -buzile inezakhi ezine eziphambili ezingahluleka, futhi ngamunye akhiqiza imithelela ehlukile, acatshangelwe ubuningi bokwenzeka lapho ijikeleza.

Lokhu kwaziwa ngokuthi ama-sufrency amabi:

• I-Ball Pass Frequency, umjaho wangaphandle (BPFO): Izinga lapho izinto ezigoqayo zidlula endaweni eyodwa emjahweni wangaphandle. Lokhu kuvame kakhulu -buzile iphutha.
• I-Ball Pass Frequency, umjaho wangaphakathi (BPFI): Izinga lapho izinto ezigoqayo zidlula endaweni eyodwa emjahweni wangaphakathi.
• I-Ball Spin Frequency (BSF): Ukujikeleza ubuningi bokwenzeka yento eyodwa yokugoqa (ibhola noma i-roller uqobo).
• Imvamisa yesitimela eyisisekelo (FTF): Ukujikeleza ubuningi bokwenzeka yekheji eliphethe izinto ezigoqayo.

Lapho ubona inani eliphakeme ku gearlika I-Spectrum, ungafanisa ubuningi bokwenzeka kwenye yalawa maphutha abilwe. Isibonelo, uma ubona inani eliphakeme elinamandla e-BPFO, ungaqiniseka kakhulu ukuthi kunomonakalo womjaho wangaphandle walokho okuqondile -buzile. Leli zinga lokunemba lokuxilonga libalulekile ekuhleleni ukulungisa okuyikho.

Ngabe utolika kanjani ukufundwa kwenani le-Ge ngezicelo ezihlukile zokufaka izicelo?

Umbuzo ojwayelekile esiwuthola e-VPK Beth uthi, "Yini 'enhle' noma okubi ' inani? "Impendulo akuyona inombolo eyodwa; kuya kakhulu ku isicelo. Ijubane eliphakeme, i-motor elayishwe kancane iyoba nesiginesha ehluke kakhulu yokudlidliza kune-pulley ehamba kancane, elayishwe kakhulu.

Nalu uhlaka olujwayelekile lokuhumusha gearlika Ukufundwa:

Ukucatshangelwa Okubalulekile:

• Sungula isisekelo: Indlela ethembekile kunazo zonke ukuthatha a ukufunda Lapho a -buzile kusha futhi kwaziwa ukuthi kuhle into efunekayo. Lesi sisekelo siba yindawo yakho yesethenjwa.
• Umkhuba, ungasabeli: Okukodwa okuphezulu ukufunda kungaba yi-anomaly. Amandla angempela we Ukuhlaziywa kokudlidliza amanga ekuthambekeni kwedatha ngokuhamba kwesikhathi. Ukukhuphuka okuqinile nokuguqukayo ku inani kuwuphawu oluqinisekile lwenkinga ekhulayo.
• Ijubane lomshini: Ama-alamu abukhali kufanele alungiswe ngokususelwa kujubane lokujikeleza lomshini. Imishini ehamba kancane ngokwemvelo iphansi gearlika amazinga.

Njengomenzi wezinhlobonhlobo ezahlukahlukene zezimboni, siyaqonda ukuthi imithwalo ehlukene futhi ishesha kanjani umthelela empilweni. Kungakho sihlale sincoma ukusungula amazinga athile aqondene ne-alamu athile.

Yiziphi izinto ezibalulekile ezithonya ukufundwa kwe-gele ngaphezu kwesimo?

Ngenkathi inani inkomba enhle ye -buzile Ezempilo, kubalulekile ukuqonda ukuthi ezinye izindaba zemishini zingathonya nokufundwa. Umhlaziyi onekhono kumele acubungule lezi zinto ukwenza ukuxilongwa okulungile futhi ugweme ukuhumusha kabusha imininingwane.

Nazi ezinye izimo ezingakhiqiza amandla afudumele aphezulu futhi zithinte okwakho gearlika Ukukalwa:

• Izinkinga zokuthambisa: Lokhu kungukukhulu. Akwanele noma acekelwa phansi ukufihlela Ibangela ukuxhumana kwensimbi-to-metal, eveza imithelela efana nephutha elibonakalayo. Sizohlola lokhu esigabeni esilandelayo.
• Izingqinamba zeGear Mesh: Ebhokisini lamagiya, ukulungiswa kwamazinyo wegiya kungakhiqiza ukudlidliza okuvame kakhulu okungase kuthathwe yi azvuzi Eseduze -buzile.
• I-Mistalignment: Ukuphazamiseka okunamandla noma okufana nokufana kungabeka okungajwayelekile thwala use -buzile, kubangela ukucindezelwa nokwenza umsindo ovame kakhulu.
