Kugadzirisa nzira ye multistage centrifugal pombi

(Pfupiso tsananguro)Nheyo yekushanda yepombi yakawanda - nhanho ye centrifugal yakafanana neyepasi centrifugal pombi.

Nheyo yekushanda yepombi yakawanda - nhanho ye centrifugal yakafanana neyepasi centrifugal pombi. Kana iyo mota ichityaira iyo impeller pane shaft kuti itenderere nekumhanya kukuru, iyo mvura yakazadzwa muimpeller inokandwa kubva pakati peipeller ichitevedza nzira yekuyerera pakati pemablades kune periphery ye impeller pasi pekuita kwe centrifugal force. Nekuda kwekuita kwemablades, iyo mvura inowedzera kudzvanywa uye kumhanya panguva imwe chete, uye inotungamirwa kune inotevera - nhanho impeller kuburikidza nekuyerera kwegwaro goko. Nenzira iyi, inoyerera nepakati pese impellers uye gwara goko rimwe nerimwe, richiwedzera kuwedzera simba rekumanikidza rekuwedzera kwemvura. Mushure mekuisa impeller yega yega nhanho nhanho, mumwe musoro unowanikwa uye mvura yepasi inosimudzwa pasi. Uyu ndiwo musimboti wekushanda wesimbi isina simbi yakawanda - nhanho pombi.
Zvinonyanya kukosha zvemultistage centrifugal pombi:
1. Vertical structure, inlet and outlet flanges iri pamutsetse mumwe wepakati, chimiro chakabatana, nzvimbo idiki, uye kuisirwa kuri nyore.
2. Iyo vertical chimiro pombi inotora chisimbiso chemuchina chechimiro chemidziyo, chinoita kuti kuisirwa uye kugadzirisa kushanda kwakachengeteka uye kwakanyanya nyore, uye kunovimbisa kuvimbika kwechisimbiso.
3. Iyo mota shaft yemulti-stage centrifugal pombi yakabatana zvakananga nepombi shaft kuburikidza nekubatanidza.
4. Iyo horizontal pombi yakashongedzerwa neakawedzera shaft mota, iyo ine chimiro chakareruka uye iri nyore kuisa nekuchengetedza.
5. Zvikamu zvinoyerera zvose zvakagadzirwa nesimbi isina tsvina, iyo isingasvibisi svikiro uye inovimbisa hupenyu hurefu hwebasa uye kutaridzika kwakanaka.
6. Mutsindo wakaderera uye kudengenyeka kuduku. Nemagadzirirwo akajairwa, ine yakanaka kuita zvakasiyana.
Ndedzipi nzira dzekugadzirisa dzemultistage centrifugal pumps? Nzira mbiri dzinonyanya kushandiswa dzinotangwa:

1. Valve throttling

Nzira iri nyore yekuchinja kuyerera kweiyo centrifugal pombi yekuvhurwa kweiyo pombi yekubuda kunze kwenyika, nepo kumhanya kweiyo pombi - Stage Centrifugal Pump isingachinji (kazhinji kumhanya kwakarongedzwa). Iyo yakakosha ndeyekuchinja chinzvimbo chePippeline hunhu curve kuti uchinje pombi yekushandisa. Iyo kupindirana kwepombi yemapomba curve curve q - h uye pombi yemapipi curve curve q - σh ndiyo muganho wekushanda pombi kana iyo vharuvhu yakavhurwa zvizere. Kana vharuvhu yakavharwa, kuramba kwenzvimbo yemapipi inowedzera, pombi inoshanda inofamba kuruboshwe, uye kuyerera kunoenderana kunoderera. Kana vharuvhu racho rakavharwa zvakakwana, rakaenzana nekuparadza kusingaperi uye zero kuyerera. Panguva ino, pombi yemapipi curvecly inoenderana neyekupedzisira. Zvinogona kuoneka kuti kana vharuvhu rikavharwa kudzora kuyerera, mari yemvura yekuwedzera. Iyi nzira iri nyore kushanda, inoenderera mberi nekuyerera, uye inogona kugadziridzwa kuChido pakati peimwe kuyerera uye neZero, pasina mari yekuwedzera, uye ine huwandu hwakawanda hwekushandisa. Nekudaro, kugadziriswa kwekukasira ndiko kupedza simba rakawandisa kweiyo centrifugal pombi yekuchengetedza, uye nekubudirira kwe pombi yementrrifugal kuchadzikira, izvo zvisiri zvehupfumi zvine hupfumi.

2. Frequency kutendeuka kumhanya mutemo

Kutsauka kwenzvimbo yekushanda kubva pakakwirira-inoshanda nzvimbo ndiyo mamiriro ekutanga ekumhanya kwepombi. Kana kukurumidza kwepombi ye-multistage centrifugal pombi inoshanduka, kuvhara kwevharuvhu kunoramba kusina kuchinjwa (kazhinji kuvhura kukuru), maitiro epombi yepombi anoramba asina kuchinjwa, uye simba rekupa mvura uye hunhu hwemusoro hunoshanduka zvichienderana. Kana kuyerera kunodiwa kuri kudiki pane kuyerera kwakatemwa, musoro weiyo frequency kutendeuka kukurumidza kudzora idiki pane yevhavha throttling, saka simba rekupa mvura rinodiwa kuti riite frequency conversion speed regulation zvakare idiki pane iyo valve throttling. Zviripachena, kana zvichienzaniswa nekupuruzira kwevharuvhu, simba - kuchengetedza mhedzisiro ye frequency conversion yekumhanyisa regulation yakakurumbira, uye kushanda zvakanaka kwehorizontal multi-stage centrifugal pumps kwakakwira. Uye zvakare, kushandiswa kweiyo frequency conversion yekumhanyisa regulation haingobatsiri kudzikisa mukana wecavitation mupombi yecentrifugal, asiwo inowedzera nguva yekutanga / yekumisa nzira nekugadzirisa kukurumidza / kudzika nguva, kuitira kuti torque ine simba ideredze zvakanyanya. , Nekudaro kubvisa inoparadza mvura sando mhedzisiro kusvika pamwero mukuru, zvakanyanya kuwedzera hupenyu hwepombi uye pombi system.

Iyo yakawanda - nhanho centrifugal pombi inotora iyo yepamusoro - kushanda nesimba uye simba - kuchengetedza hydraulic modhi inokurudzirwa nenyika. Iyo ine mabhenefiti ehukuru hwepamusoro uye kuchengetedza simba, yakafara dhizaini, yakachengeteka uye yakagadzikana kushanda, yakaderera ruzha, hupenyu hurefu, kuisirwa nyore uye kugadzirisa, nezvimwe; nekushandura zvinhu zvepombi, fomu yekuisa chisimbiso uye kuwedzera kutonhora Iyo sisitimu inogona kutakura mvura inopisa, mafuta, corrosive uye abrasive media, etc. Different multi-stage centrifugal pump vagadziri vanogadzira mhando dzakasiyana dzemapombi akawanda - stage centrifugal. Multi-stage centrifugal pombi dzinobatanidza pombi mbiri kana kupfuura dzine basa rimwechete pamwechete. Chimiro cheiyo fluid chiteshi chinoratidzwa mune media media pressure relief port uye yekutanga nhanho. Iyo inlet yechikamu chechipiri yakabatana, uye yepakati kudzvinyirira chiteshi chechikamu chechipiri chakabatana nekupinda kwechikamu chechitatu. Yakatevedzana yakadaro-yakabatana meshini inoumba multi-stage centrifugal pombi. Kukosha kwepombi yemultistage centrifugal ndeyekuwedzera kudzvanywa kweseti.
