Uma iphampu isebenza ngesivinini esiphezulu futhi isesimweni sokugeleza okuphansi, imiphumela eminingana ingenzeka.
Ngokuya ngobungozi bokulimala kwengxenye yemishini:
- Ku-impeller: Uma iphampu ishesha kakhulu, isivinini esiyindilinga se-impeller sidlula inani lokuklama. Ngokwefomula ye-centrifugal force (lapho i-centrifugal force, inqwaba ye-impeller, isivinini esiyindilinga, futhi iyiradiyasi ye-, iholela ekwenyukeni okukhulu kwamandla amaphakathi. Lokhu kungabangela ukwakheka kwe-impeller ukuthi kuthwale ngokweqile ukucindezeleka, okuholela ekuwohlokeni noma ngisho nokuphuka kwe-impeller Ngokwesibonelo, kwamanye amaphampu e-centrifugal anesivinini esiphezulu, kanye i-impeller ruptures, izindwani eziphukile zingangena kwezinye izingxenye zomzimba wepompo, okubangela umonakalo omkhulu kakhulu.
- Ku-shaft nama-bearings: Ukusheshisa ngokweqile kwenza i-shaft ijikeleze ngaphezu kwezinga lokuklama, okwandisa i-torque kanye nomzuzu wokugoba ku-shaft. Lokhu kungase kubangele ukuthi i-shaft igobe, ithinte ukunemba okufanele phakathi kwe-shaft nezinye izakhi. Isibonelo, ukugoba kwe-shaft kungase kuholele kugebe elingalingani phakathi kwe-impeller ne-pump casing, okuqhubekisela phambili ukudlidliza nokuguga. Kuma-bearings, ukusebenza ngesivinini esiphezulu kanye nokugeleza okuphansi kwenza izimo zabo zokusebenza zibe zimbi kakhulu. Njengoba ijubane landa, ukushisa okungqubuzanayo kwama-bearings kukhuphuka, futhi ukusebenza okugeleza okuphansi kungase kuthinte ukugcoba kanye nemiphumela yokupholisa yama-bearings. Ngaphansi kwezimo ezijwayelekile, ama-bearings ancike ekujikelezeni kwamafutha okugcoba epompo ukuze kukhishwe ukushisa nokugcoba, kodwa ukuhlinzekwa nokujikeleza kwamafutha okugcoba kungase kuthinteke esimweni sokugeleza okuphansi. Lokhu kungase kuholele ekuthwaleni izinga lokushisa elingaphezu kwamandla, kubangele ukuguga, ukuklolodela, nomunye umonakalo kumabhola aphethe noma imigwaqo yomjaho, futhi ekugcineni kubangele ukwehluleka ukuthwala.
- Okwezimpawu: Izigxivizo zephampu (njengezigxivizo zemishini kanye nezigxivizo zokupakisha) zibalulekile ekuvimbeleni ukuvuza koketshezi. Ukusheshisa ngokweqile kwandisa ukuguga kwezimpawu ngoba isivinini esihlobene phakathi kwezimpawu nezingxenye ezijikelezayo siyakhula, futhi amandla okungqubuzana nawo ayanda. Emsebenzini wokugeleza okuphansi, ngenxa yesimo sokugeleza esingazinzile soketshezi, ukucindezela emgodini we-seal kungase kuguquke, kuphazamise nakakhulu umphumela wokuvala. Isibonelo, indawo yokuvala phakathi kwezindandatho ezimile nezizungezayo zesigxivizo esisetshenziswayo ingase ilahlekelwe ukusebenza kwayo kokuvala ngenxa yokuguquguquka kwengcindezi kanye nokungqubuzana kwesivinini esikhulu, okuholela ekuvuzeni koketshezi, okungathinti nje kuphela ukusebenza okuvamile kwephampu kodwa futhi kungase kubangele. ukungcoliswa kwemvelo.
Mayelana nokwehliswa kokusebenza nokwehliswa kokusebenza kahle:
- Ekhanda: Ngokomthetho wokufana wamaphampu, lapho iphampu ishesha kakhulu, ikhanda liyakhula ngokulingana nesikwele sejubane. Kodwa-ke, ekusebenzeni kokugeleza okuphansi, ikhanda langempela lepompo lingase libe phezulu kunekhanda elidingekayo lesistimu, okubangela ukuthi indawo yokusebenza yephampu iphambuke endaweni yokusebenza kahle kakhulu. Ngalesi sikhathi, iphampu isebenza ekhanda eliphezulu ngokungadingekile, ichitha amandla. Ngaphezu kwalokho, ngenxa yokugeleza okuncane, ukumelana nokugeleza kwe-liquid empompini kuyanda, okuqhubeka kunciphisa ukusebenza kahle kwepompo.
- Ngokusebenza kahle: Ukusebenza kahle kwepompo kuhlobene eduze nezici ezifana nokugeleza nekhanda. Emsebenzini wokugeleza okuphansi, ama-vortex kanye ne-backflow phenomena kwenzeka ekugelezeni koketshezi epompo, futhi lokhu kugeleza okungavamile kwandisa ukulahlekelwa kwamandla. Ngesikhathi esifanayo, ukulahlekelwa okungqubuzanayo phakathi kwezingxenye zemishini nakho kuyanda ngesikhathi sokushesha kakhulu, kunciphisa ukusebenza kahle okuphelele kwepompo. Isibonelo, empompini eyi-centrifugal esebenza kahle ngokujwayelekile okungu-70%, ekusebenzeni okushesha kakhulu nokugeleza okuphansi, ukusebenza kahle kungase kwehle kuze kufike ku-40% - 50%, okusho ukuthi amandla amaningi ayamoshwa ekusebenzeni kwephampu kunokuba ukuthutha uketshezi.
Mayelana nokumosha amandla kanye nezindleko zokusebenza ezikhuphukile:
Lokhu kuholela ekwenyukeni okukhulu kokusetshenziswa kwamandla kanye nezindleko zokusebenza. Isibonelo, iphampu eqala ukusebenzisa ama-kilowatt-amahora ayi-100 kagesi ngosuku ingase ikhulise ukusetshenziswa kwayo kwamandla ukuya ku-150 - 200 kilowatt-hour kuleso simo sokusebenza esingesihle. Ngokuhamba kwesikhathi, kuzodala ukulahlekelwa okukhulu kwezomnotho ebhizinisini.
Ekugcineni, ingozi ye-cavitation iyanda:
Emsebenzini wokugeleza okuphansi, isivinini sokugeleza kwe-liquid endaweni yokungena yepompo siyehla, futhi ingcindezi ingase yehle. Ngokomgomo we-cavitation, lapho ingcindezi endaweni yepompo iphansi kunokucindezela komhwamuko ogcwele uketshezi, uketshezi luyahwamuka kwenze amabhamuza. Lawa ma-bubbles azowa ngokushesha lapho engena endaweni yokucindezela okuphezulu kwepompo, ekhiqiza amagagasi okushisa aphezulu wendawo futhi abangele ukulimala kwe-cavitation ezingxenyeni ezifana ne-impeller ne-pump casing. Ukusheshisa ngokweqile kungase kukhulise lesi simo se-cavitation ngoba izinguquko zokusebenza kwepompo zingase ziwohloke nakakhulu izimo zokucindezela endaweni yokungena. I-Cavitation izodala i-pitting, izimbobo ezifana nekhekheba lezinyosi, nomunye umonakalo endaweni ye-impeller, okuthinta kakhulu ukusebenza kwepompo kanye nempilo yesevisi.
Ukuze uthole okwengeziwe mayelana namaphampu anodaka, sicela uthinte iphampu ye-Rita-Ruite
