Xa ipompo isebenza ngesantya esiphezulu kwaye kwisimo sokuhamba okuphantsi, iziphumo ezininzi zingenzeka.
Ngokwecandelo loomatshini imingcipheko yomonakalo:
- Kwi-impeller: Xa umpompo ugqithise-isantya esiphezulu, isantya se-circumferential se-impeller sidlula ixabiso loyilo. Ngokwefomula yamandla e-centrifugal (apho i-centrifugal force, bubunzima be-impeller, isantya sokujikeleza, kwaye yiradiyasi ye, ikhokelela ekonyukeni okubonakalayo kwamandla ase-centrifugal. Oku kunokubangela ukuba ulwakhiwo lwe-impeller luthwale ngokugqithisileyo uxinzelelo, okubangela deformation okanye nokugqabhuka impeller Umzekelo, kwezinye-speed ezininzi iimpompo centrifugal, kanye i-impeller ruptures, ii-blades eziphukileyo zingangena kwezinye iindawo zomzimba wempompo, zibangele umonakalo omkhulu.
- Kwi-shaft kunye neebheringi: I-over-speeding yenza i-shaft ijikeleze ngaphaya komgangatho woyilo, ukwandisa i-torque kunye nomzuzu wokugoba kwi-shaft. Oku kunokubangela ukuba i-shaft igobe, ichaphazela ukuchaneka okufanelekileyo phakathi kwe-shaft kunye namanye amacandelo. Ngokomzekelo, ukugoba kwe-shaft kunokukhokelela kwisithuba esingalinganiyo phakathi kwe-impeller kunye ne-casing yempompo, ukuqhubela phambili ukungcangcazela kunye nokunxiba. Kwiibheringi, ukusebenza ngesantya esiphezulu kunye nokuhamba okuphantsi kuzenza zibe mandundu iimeko zabo zokusebenza. Njengoko isantya sanda, ukushisa okukhukhulayo kweebheringi kuphakama, kwaye umsebenzi ophantsi-phantsi unokuchaphazela i-lubrication kunye nemiphumo yokupholisa yeebheringi. Ngaphantsi kweemeko eziqhelekileyo, iibheringi zixhomekeke ekujikelezeni kweoli yokuthambisa kwimpompo yokutshatyalaliswa kobushushu kunye ne-lubrication, kodwa ukunikezelwa kunye nokujikeleza kweoli ye-lubricating kunokuchaphazeleka kwimeko ephantsi. Oku kunokukhokelela kubushushu obugqithisileyo, kubangele ukuguga, ukukruneka, kunye nomnye umonakalo kwiibhola ezithweleyo okanye kwiindlela zomdyarho, kwaye ekugqibeleni kubangele ukusilela.
- Kumatywina: Izitywina zempompo (ezifana nezitywini zoomatshini kunye nokupakisha amatywina) zibalulekile ekuthinteleni ukuvuza kolwelo. Ukuhamba ngesantya esiphezulu kwandisa ukunxiba kwezitywina kuba isantya esihambelanayo phakathi kwamatywina kunye neendawo ezijikelezayo ziyanda, kwaye amandla okhuhlane nawo ayanda. Kumsebenzi wokuhamba okuphantsi, ngenxa yokungazinzi kobume be-liquid, uxinzelelo kwi-cavity yesitywina lunokuguquka, luchaphazele ngakumbi umphumo wokutywinwa. Umzekelo, umphezulu wokutywina phakathi kwamakhonkco amileyo kunye ajikelezayo etywina lomatshini unokuphulukana nokusebenza kwawo okutywinwa ngenxa yokuguquguquka koxinzelelo kunye nokukhuhlana okuhamba ngesantya esiphezulu, okukhokelela ekuvuzeni kolwelo, okungachaphazeli nje ukusebenza okuqhelekileyo kwempompo kodwa kunokubangela. ukungcoliseka kwendalo.
Ngokumalunga nokuthotywa komgangatho wokusebenza kunye nokunciphisa ukusebenza kakuhle:
- Ngentloko: Ngokomthetho wokufana kweempompo, xa umpompo ugqithise isantya, intloko iyanda ngokulinganayo kwisikwere sesantya. Nangona kunjalo, ekusebenzeni okuphantsi, intloko yangempela yempompo ingaba phezulu kunentloko efunekayo yenkqubo, ebangela ukuba indawo yokusebenza yempompo iphambuke kwindawo efanelekileyo yokusebenza. Ngeli xesha, ipompo isebenza kwintloko ephezulu ngokungeyomfuneko, ichitha amandla. Ngaphezu koko, ngenxa yokuhamba okuncinci, ukuchasana kokuhamba kwamanzi kwimpompo kuyanda, kunciphise ngakumbi ukusebenza kwempompo.
- Ukusebenza kakuhle: Ukusebenza kwempompo kuhambelana ngokusondeleyo nezinto ezifana nokuhamba kunye nentloko. Kwi-low-flow operation, i-vortexes kunye ne-backflow phenomena zenzeka kwi-liquid flow in pump, kwaye oku kuhamba okungaqhelekanga kwandisa ukulahlekelwa kwamandla. Kwangaxeshanye, ilahleko yokungqubana phakathi kwamacandelo omatshini nawo ayanda ngexesha lokuhamba ngesantya esiphezulu, ukunciphisa ukusebenza kakuhle kwempompo. Umzekelo, kwimpompo ye-centrifugal enokusebenza okuqhelekileyo kwe-70%, kwi-over-speeding kunye ne-low-flow operation, ukusebenza kakuhle kunokuncipha ukuya kuma-40% - 50%, oku kuthetha ukuba amandla amaninzi achithwa ekusebenzeni kwempompo kunokuba kusebenze. ukuthutha ulwelo.
Ngokubhekiselele kwinkcitho yamandla kunye nokunyuka kweendleko zokusebenza:
Oku kukhokelela ekunyukeni okukhulu kokusetyenziswa kwamandla kunye neendleko zokusebenza. Umzekelo, impompo esebenzisa i-100 kilowatt-iiyure zombane ngosuku inokunyusa amandla ayo ombane ukuya kuma-150 - 200 eekhilowatt-iiyure kwimeko yokusebenza kakubi ngolo hlobo. Ekuhambeni kwexesha, iya kubangela ilahleko enkulu yezoqoqosho kwishishini.
Ekugqibeleni, umngcipheko we-cavitation uyanda:
Kwi-low-flow operation, i-liquid flow velocity kwi-inlet inlet iyancipha, kwaye uxinzelelo lunokuhla. Ngokomgaqo we-cavitation, xa uxinzelelo kwi-inlet yempompo iphantsi kunoxinzelelo lwe-saturated vapor yolwelo, ulwelo luyaphuphuma ukuze lube namaqamza. Ezi bhubhu ziya kuwela ngokukhawuleza xa zingena kwindawo yoxinzelelo oluphezulu lwempompo, ukuvelisa amaza okutshatyalaliswa kwendawo kunye nokubangela umonakalo we-cavitation kumacandelo afana ne-impeller kunye ne-pump casing. Ukugqithisa ngokukhawuleza kunokunyusa le nto ye-cavitation ngenxa yokuba ukuguqulwa kokusebenza kompompo kunokunyusa ngakumbi iimeko zoxinzelelo kwi-inlet. I-Cavitation iya kubangela i-pitting, i-honeycomb-like holes, kunye nolunye umonakalo kwi-surface impeller, echaphazela kakhulu ukusebenza kompompo kunye nobomi benkonzo.
