Apo pombi inoshanda pa-over-speed uye mumamiriro ekuderera-kuyerera, migumisiro yakawanda inogona kuitika.
Panyaya yemechanical chikamu kukuvara njodzi:
- Kune iyo impeller: Kana pombi iri pamusoro-kumhanya, iyo circumferential kumhanya kweiyo impeller inodarika kukosha kwekugadzira. Zvinoenderana ne centrifugal force formula (pane pane simba re centrifugal, ndiko kuwanda kwe indeller, ndiko kumhanya kwe circumferential, uye radius ye,inotungamira kukuwedzera kukuru kwe centrifugal simba. kushushikana, zvichiita kuti deformation kana kunyange kuputika impeller Somuenzaniso, mune dzimwe high-speed multi-stage centrifugal pombi, kamwe impeller kuputika, mashizha akaputsika anogona kupinda mune dzimwe nzvimbo dzepombi yepombi, zvichikonzera kukanganisa kwakanyanya.
- Kune shaft nemabhengi: Kuwedzeresa-kumhanyisa kunoita kuti shaft itenderere kupfuura chiyero chekugadzira, ichiwedzera torque uye nguva yekukotama pane shaft. Izvi zvinogona kuita kuti shaft ikotame, inokanganisa kurongeka kwakakodzera pakati peshaft uye zvimwe zvikamu. Semuenzaniso, kukotama kweshaft kunogona kutungamira kune mukaha usina kuenzana pakati pemapombi uye pombi casing, zvichiwedzera kuwedzera vibration uye kupfeka. Kune mabearings, kukurumidza-kumhanya uye kuderera-kuyerera kunowedzera mamiriro avo ekushanda. Sezvo kukurumidza kunowedzera, kupisa kunopisa kwemabhengi kunokwira, uye kushanda kwepasi-kuyerera kunogona kukanganisa mafuta uye kutonhora kwemaitiro. Mumamiriro ezvinhu akajairwa, mabheji anovimba nekutenderera kwemafuta ekuzora mupombi yekupisa kupisa uye mafuta, asi kupihwa uye kutenderera kwemafuta ekuzora kunogona kukanganiswa mumamiriro ekuderera-kuyerera. Izvi zvinogona kutungamira kune yakanyanyisa kubereka tembiricha, zvichikonzera kusakara, scuffing, uye kumwe kukuvadza kune anotakura mabhora kana mijaho, uye pakupedzisira zvichikonzera kutadza kubereka.
- Zvezvisimbiso: Zvisimbiso zvepombi (zvakadai semakanika zvisimbiso uye kurongedza zvisimbiso) zvakakosha kudzivirira kubuda kwemvura. Kuwedzera-kumhanya kunowedzera kupfeka kwezvisimbiso nokuti kukurumidza kukurumidza pakati pezvisimbiso uye zvikamu zvinotenderera zvinowedzera, uye simba rinoputika rinowedzerawo. Mukushanda kwakadzika-kuyerera, nekuda kwekusagadzikana kwekuyerera kwemvura, kudzvanywa kwechisimbiso mhango kunogona kuchinjika, kuchiwedzera kukanganisa chisimbiso mhedzisiro. Semuenzaniso, nzvimbo yekuisa chisimbiso pakati peyakamira uye inotenderera mhete dzemuchina chisimbiso inogona kurasikirwa nekuita kwayo yekuisa chisimbiso nekuda kwekusimba kwekuchinja uye kumhanyisa-kumhanya, zvichitungamira mukudonha kwemvura, izvo zvisingangokanganisa kushanda kwakajairika kwepombi asiwo zvinogona kukonzera. kusvibiswa kwezvakatipoteredza.
Nezve kuderedzwa kwekuita uye kudzikiswa kwehunyanzvi:
- Kumusoro: Zvinoenderana nemutemo wekufanana kwemapombi, kana pombi ichimhanya-mhanya, musoro unowedzera zvakaenzana nechikwere chekumhanya. Zvisinei, mukushanda kwepasi-kuyerera, musoro chaiwo wepombi unogona kunge wakakwirira kudarika musoro unodiwa wegadziriro, zvichiita kuti pombi yepombi ienderere mberi kubva panzvimbo yakanakisisa yekushanda. Panguva ino, pombi inoshanda pane zvisina kufanira musoro wepamusoro, inoparadza simba. Uyezve, nekuda kwekuyerera kudiki, kuyerera kwemvura mupombi kunowedzera, zvichiwedzera kuderedza kushanda kwepombi.
- Nokuda kwekushanda: Kushanda kwepombi kwakanyatsoenderana nezvinhu zvakadai sekuyerera uye musoro. Mukushanda kwakaderera-kuyerera, mavortex uye backflow phenomena anoitika mukuyerera kwemvura mupombi, uye aya asina kujairika anoyerera anowedzera kurasikirwa kwesimba. Panguva imwecheteyo, kurasikirwa kwekukakavadzana pakati pema mechanical components kunowedzerawo panguva ye-over-speeding, kuderedza kushanda kwakakwana kwepombi. Semuyenzaniso, papombi yecentrifugal ine 70% inoshanda zvakanaka, mukumhanya-mhanya uye kuyerera kwakaderera, kushanda kwayo kunogona kudzikira kusvika pa40% - 50%, zvinoreva kuti simba rakawanda rinoparara mukushanda kwepombi kwete mu. kutakura mvura.
Panyaya yekuraswa kwesimba uye kuwedzera mari yekushandisa:
Izvi zvinotungamirira kukuwedzera kukuru kwesimba rekushandisa uye mari yekushandisa. Semuenzaniso, pombi inotanga kushandisa 100 kilowatt-maawa emagetsi pazuva inogona kuwedzera simba rayo rekushandisa kusvika ku150 - 200 kilowatt-maawa mumamiriro ezvinhu asina kunaka akadaro. Mukufamba kwenguva, zvinozokonzera kurasikirwa kukuru kwehupfumi kune bhizinesi.
Pakupedzisira, njodzi ye cavitation inowedzera:
Mukushanda kwakaderera-kuyerera, mvura inoyerera velocity papombi inopinza inoderera, uye kudzvinyirira kunogona kuderera. Zvinoenderana neiyo cavitation musimboti, kana kudzvanywa kwepombi kwepombi kwakadzikira pane yakazara mhute yekumanikidza yemvura, iyo mvura inoputika kuita mabhubhu. Aya mabhubhu achakurumidza kudonha kana achipinda munzvimbo yepamusoro-yekudzvanya yepombi, achigadzira mafungu epamhepo-kudzvanya mafungu uye achikonzera kukuvadzwa kwecavitation kune zvikamu senge impeller uye pombi casing. Kuwedzera-kumhanya kunogona kuwedzera chiitiko ichi che cavitation nokuti kuchinja kwekushanda kwepombi kunogona kuwedzera kuipa kwemamiriro ekumanikidzika pane inopinza. Cavitation inokonzeresa gomba, maburi euchi-senge maburi, uye kumwe kukuvadza pane impeller, zvichikanganisa zvakanyanya kushanda kwepombi uye hupenyu hwebasa.
