Ngesikhathi sokusebenza kwe- icala lokuhlukanisa amaphampu, ukudlidliza okungamukeleki akufunwa, njengoba ukudlidliza akugcini nje ukumosha izinsiza namandla, kodwa futhi kudala umsindo ongadingekile, futhi kulimaza ngisho nepompo, okungaholela ezingozini ezimbi kakhulu kanye nokulimala. Ukudlidliza okuvamile kubangelwa izizathu ezilandelayo.

1. I-Cavitation

I-Cavitation ivamise ukukhiqiza amandla e-broadband angahleliwe aphezulu, kwesinye isikhathi agqitshwe ngama-harmonics we-blade pass frequency (ama-multiple). I-Cavitation iwuphawu lwekhanda lokumunca elinetha elihle elinganele (NPSH). Lapho uketshezi olumpontshwa lugeleza ezindaweni ezithile zendawo zezingxenye zokugeleza ngesizathu esithile, ukucindezela okuphelele koketshezi kuyehla kuye kumfutho womoya ogcwele (umfutho wokuhwamuka) woketshezi ekushiseni okumpompayo, uketshezi luyahwamuka lapha, lukhiqize umusi, amaBubbles. kwakheka; ngesikhathi esifanayo, igesi encibilikisiwe oketshezini izophinde iqhume ngendlela yama-bubbles, yakha ukugeleza kwezigaba ezimbili endaweni yendawo. Lapho ibhamuza liya endaweni enomfutho ophezulu, uketshezi olunomfutho ophezulu ozungeze ibhamuza luzojiya ngokushesha, lushwabane futhi luqhumise ibhamuza. Ngaleso sikhathi lapho ibhamuza lijiya, lishwabana, futhi liqhuma, uketshezi oluzungeze ibhamuza luzogcwalisa umgodi (okwakhiwa ukufingqa nokugqabuka) ngesivinini esikhulu, kukhiqize igagasi elinamandla lokushaqeka. Le nqubo yokukhiqiza amabhamuza nokuqhuma kwamabhamuza ukulimaza izingxenye ezidlulayo yinqubo ye-cavitation yepompo. Ukuwa kwamabhamuza esitimu kungalimaza kakhulu futhi kungalimaza iphampu kanye ne-impeller. Uma i-cavitation yenzeka empompini yekesi ehlukanisiwe, kuzwakala sengathi "amamabula" noma "amatshe" adlula epompo. Kuphela uma i-NPSH edingekayo yephampu (NPSHR) iphansi kune-NPSH yedivayisi (NPSHA) ingagwenywa i-cavitation.

2. Iphampu flow pulsation

I-Pump pulsation yisimo esenzeka lapho iphampu isebenza eduze kwekhanda layo elivalayo. Ukudlidliza kufomethi yegagasi yesikhathi kuzoba yi-sinusoidal. Futhi, i-spectrum isazobuswa yi-1X RPM namafrikhwensi e-blade pass. Kodwa-ke, lezi ziqongo zizobe ziguquguquka, zikhule futhi zinciphe njengoba ukugeleza kokugeleza kwenzeka. Igeji yokucindezela epayipini lokuphuma kwephampu izoguquguquka iye phezulu naphansi. Uma iiphampu yecala lokuhlukanisai-outlet ine-valve yokuhlola ukujika, ingalo ye-valve ne-counterweight izogxuma iye phambili naphambili, okubonisa ukugeleza okungazinzile.

3. I-pump shaft igobile

Inkinga ye-shaft egobile ibangela ukudlidliza kwe-axial okuphezulu, okunomehluko wesigaba se-axial othambekele ku-180° ku-rotor efanayo. Uma ukugoba kuseduze nendawo emaphakathi ye-shaft, ukudlidliza okubusayo kuvame ukwenzeka ngo-1X RPM; kodwa uma ukugoba kuseduze nokuhlangana, ukudlidliza okubusayo kwenzeka ngo-2X RPM. Kuvame kakhulu ukuthi i-pump shaft igobe eduze noma eduze nokuhlangana. Igeji yokudayela ingasetshenziswa ukuze kuqinisekiswe ukuchezuka kwe-shaft.

4. I-pump impeller engalingani

Ama-split case pump pumps kufanele alinganisele ngokunembile kumkhiqizi wephampu wangempela. Lokhu kubaluleke kakhulu ngoba amandla abangelwa ukungalingani angathinta kakhulu impilo ye-pump bearings (ukuphila okuthwalayo kuhambisana ngokuphambene ne-cube yomthwalo onamandla osetshenzisiwe). Amaphampu angase abe nama-impeller alenga phakathi nendawo noma ama-cantilevered. Uma i-impeller ilenga phakathi nendawo, ukungalingani kwamandla ngokuvamile kudlula ukungalingani kombhangqwana. Kulokhu, ukudlidliza okuphezulu kakhulu kuvamise ukuba kuhlangothi lwe-radial (oluvundlile futhi oluqondile). I-amplitude ephakeme kakhulu izoba ngesivinini sokusebenza sephampu (1X RPM). Endabeni yokungalingani kwamandla, izigaba ezivundlile ezingemuva nezimaphakathi zizocishe zifane (+/- 30°) njengezigaba eziqondile. Ukwengeza, izigaba ezivundlile nezime mpo zephampu ngayinye ethwele ngokuvamile zihluka cishe ngo-90° (+/- 30°). Ngokuklama kwayo, i-impeller emiswe maphakathi inama-axial forces abhalansi kuma-bearings angaphakathi nangaphandle. Ukudlidliza kwe-axial okuphakeme kuwuphawu oluqinile lokuthi isixhumi sepompo sivinjwe izinto zangaphandle, okubangela ukudlidliza kwe-axial ukuthi kukhuphuke ngokuvamile ngesivinini sokusebenza. Uma iphampu ine-impeller e-cantilevered, lokhu ngokuvamile kubangela i-axial ephezulu kakhulu ne-radial 1X RPM. Ukufundwa kwe-axial kuvame ukuba sesigaba futhi kuzinzile, kuyilapho ama-rotor angama-cantilevered anokufundwa kwesigaba se-radial okungenzeka angazinzi abe nakho kokubili amandla nokungalingani okubili, okungase kudingeke ukulungiswa. Ngakho-ke, izisindo zokulungisa ngokuvamile kufanele zibekwe ezindizeni ezi-2 ukuze zimelane namandla nokungalingani kwabashadile. Kulesi simo ngokuvamile kudingekile ukususa i-rotor yepompo bese uyibeka emshinini wokulinganisa ukuze ulinganise ngokunemba okwanele njengoba izindiza ze-2 ngokuvamile azitholakali kusayithi lomsebenzisi.

5. Ukungahambi kahle kwe-pump shaft

Ukungahambi kahle kwe-shaft yisimo sepompo yokushayela eqondile lapho imigqa ephakathi kwama-shafts amabili axhunyiwe ingahambelani. Ukungaqondani kahle okuhambisanayo kuyisimo lapho imigqa emaphakathi ye-shaft ihambisana kodwa isuka komunye nomunye. I-spectrum yokudlidliza ngokuvamile izobonisa i-1X, 2X, 3X... ephezulu, futhi ezimeni ezinzima, ama-harmonics aphakeme kakhulu azovela. Esiqondisweni se-radial, isigaba sokuhlanganisa Umehluko ngu-180 °. Ukungaboni kahle kwe-angular kuzobonisa i-axial 1X ephezulu, enye engu-2X kanye ne-3X, 180° isigaba sokuphuma kwesigaba kuzo zombili iziphetho zokuhlangana.

6. Inkinga yokuthwala iphampu

Iziqongo kumafrikhwensi angavumelani (kuhlanganise nama-harmonics) yizimpawu zokuguga okuthwele. Ukuphila okufushane okuthwalayo kumaphampu ekesi ehlukanisiwe kuvame ukuba umphumela wokukhetha okungekuhle komkhiqizo wohlelo, njengemithwalo eningi, ukugcotshwa okungekuhle noma amazinga okushisa aphezulu. Uma uhlobo oluthwalayo kanye nomkhiqizi baziwa, imvamisa ethile yokuhluleka kwendandatho yangaphandle, indandatho yangaphakathi, izakhi ezigoqayo kanye nekheji kunganqunywa. Lezi mvamisa zokwehluleka zalolu hlobo lokuthwala zingatholakala kumathebula kuma-software amaningi e-predictive maintenance (PdM) namuhla.
