Kurasikirwa kwehuwandu uye kudzivirira kurasikirwa kwe slurry pombi
Kurasikirwa kwevhoriyamu centrifugal china slurry pombi seal ring ring leakage kurasikirwa, kurasikirwa kwechiyero pakati pemasangano uye nhanho yekudonha yekudonha kurasikirwa.
A seal ring leakage kurasikirwa
Mune impeller inlet, mhete yekuisa chisimbiso muchina slurry pombi basa, nekuti zvindori zvekuisa chisimbiso pamativi ese kune mutsauko wekumanikidza, parutivi rwekumanikidza kubuda kwemhepo kunenge kune rumwe rutivi rweimpeller inlet pressure, saka pachagara paine. chikamu chemvura kubva kune impeller outlet kuenda kune impeller inlet leakage .Ichi chikamu chemvura inowanikwa musimba re impeller, asi mvura yacho haina kutumirwa, nokudaro kuderedza kuwanda kwemvura china slurry pump .Iro simba rese rinoshandiswa kukurira kuvuza kweiyo fluid seal ring pane inopikisa.
Zviripachena, iyo yakakura iyo chisimbiso mhete dhayamita Dw, iyo yakanyanya kushata pamativi ese emusiyano wekumanikidza, iyo yakakura kuwanda kwekudonha.Kune stereotypes china slurry pombi, kuitira kuderedza kuwanda kwekudonha kwekuvandudza kushanda kwechina slurry pombi inofanirwa kubvumidzwa mune yekuvharisa mhete gap kuderera.Kazhinji fungidziro yakazara yekubvumidza chisimbiso mhete dhayamita 0.002, seDw = 200 mm, iyo yakazara clearance ye0.40 mm.Kana yaunganidzwa, mhete yechisimbiso eccentrically kwete yakakura kwazvo, kana zvisina kudaro, huwandu hwekudonha huchawedzera.Imwe nhanho dzinokosha dzinoshandiswa kuwedzera kushorwa kwechisimbiso chemhete nzira yekudzikisa kuwanda kwekudonha, kuwedzera kushorwa kwechisimbiso mhete kunoitwa ??ye maze, zigzag, etc. Inowedzerawo kureba kwechisimbiso chisimbiso chisimbiso, kuwedzera kushorwa munzira .
Kubuda kwechisimbiso mhete, uye mune dzimwe nguva kunogona kukonzera kukanganisa kweiyo impeller inlet, saka dhizaini inofanirwa kuumba mhete yechisimbiso.
Chechipiri, the balance mechanism leakage kurasikirwa
Mune akawanda ecentrifugal china slurry pombi, axial thrust balancing inoratidzira masangano: senge maburi ekuyeresa, chiyero chekudzora, chiyero disc.Sezvo paine mativi maviri ekuyeresa kudzvanya kusiyanisa masisitimu, uye nekudaro chikamu chemvura inodonha kubva kunzvimbo yakakwira yekumanikidza kuenda kunzvimbo yakaderera.Inenge 5% kudzikisa gomba rekudonha kwaizodzikamisa kushanda kwechina slurry pombi.Mukuenzanisa disc institution, leakage accounts ye3% yebasa rekuyerera, asi mamwe epamusoro-pressure china slurry pump yakakura kupfuura iyi;kuitira kuti uderedze kurasikirwa kwekudonha kunogona kuderedzwa chiyero disc dhayamita D pasina kukanganisa counterweight mamiriro '.
Chechitatu, iyo interstage leakage kurasikirwa
Mune iyo yakawanda-nhanho volute china slurry pombi, iyo nhanho yepakati pamativi ese maviri ekumanikidza ndiro renji, saka kune kurasikirwa kwekudonha, zvichienderana nekurongeka kweakasiyana masangano, nhanho yekumanikidza pamativi ese emaplateti e spacer inogona kunge iri yekutanga, chechipiri kana chepamusoro , iyo yakawanda nhanho inosiyana , ipapo iyo yakanyanya kudonha kuvuza pakati pechikamu chekuparadzanisa , saka pano inoshandiswa zvakanyanya pakati pechisimbiso chakatsikwa.
Kupfuurirazve, mune yakawanda-nhanho china slurry pombi segment, kune inter-stage leakage.Asi uku kudonha pakati peyakambotaurwa nhanho yakasiyana, nekuti ichi chikamu chemvura hachibvisi kuburikidza ne impeller, hachisi chekurasikirwa kwevhoriyamu.Pano, chiyero chekumanikidzika chakakomberedza plate partition, yakamanikidzwa nekupararira kwekuita kwevanees ye impeller-side chikamu uye gap rekusveta (yakaenzana ne centrifugal impeller) yakakonzerwa.Mune basa rekusiyanisa kudzvanywa, kuvuza kwemvura yenhanho yenguva padivi pebhodhi isati yapinda mune impeller gap backlash, uye negwara vanes, ABM shizha (inhalation guide vanes) uye kudzokera mugomba pakati pezinga, dzokorora maitiro.Kunyangwe kupindirana-chikamu chechina slurry pombi kuvuza mwero haisi yekurasikirwa nevhoriyamu, asi inoyerera ichienda kuchina slurry pombi yekushandisa simba.Mukuwedzera, chikamu chemvura kuburikidza nevanotungamira vanes, vane huro huchaita kuti chikamu chemuchinjikwa chinoshanda chinoderera (kureva, kubuda kwemvura kunotora chikamu chechikamu chemuchinjikwa), ichawedzera kuyerera pano, zvichikonzera kurasikirwa kwe hydraulic. .Zvinoenderana ne "centrifugal china slurry pombi dhizaini dhizaini," bhuku rinenge : a multi-stage china slurry pombi , pakuyerera kwe20 l / s, gap riri pakati pedanho rinodzikira kubva 0.75 mm kusvika 0.25 mm, interstage leakage quantity. q kuderera kwe0.7 litita / sec.nekuda kwekuderedzwa kwe q, kuyerera kunopfuura nepakati pemavhanes kunoderedzwa, kuderedza kuyerera kwevane huro, kuderedza kurasikirwa kwemvura mumavheni, uye nekuti q inoderedza kukurumidza kweiyo impeller iyo mvura inosiya inotungamira slot mukati. rutivi rwakaderedzwa, nokudaro kuderedza friction kurasikirwa kwe impeller disc, saka china slurry pombi kushanda zvakanaka kunovandudzwa ne5%.
