Umpompo oxutywe ngokupheleleyo we-shaft odibeneyo wepompo luhlobo lwempompo ephakathi kunye nobukhulu obukhulu obusebenzisa i-angle ye-angle adjuster ukuqhuba ii-pump blades ukuze zijikeleze, ngaloo ndlela zitshintsha i-angle yokubeka i-blade ukufezekisa ukuhamba kunye nokutshintsha kwentloko. Eyona ndlela yokuhambisa ngamanzi acocekileyo okanye ilindle elilula ku-0~50℃ (ijelo leendaba elikhethekileyo liquka amanzi olwandle kunye namanzi oMlambo oMthubi). Isetyenziswa kakhulu kwimimandla yeeprojekthi zogcino lwamanzi, ukunkcenkceshela, ukuhanjiswa kwamanzi kunye neeprojekthi zokuphambukisa amanzi, kwaye isetyenziswa kwiiprojekthi ezininzi zesizwe ezifana neProjekthi yokuNyula aManzi aMazantsi ukuya kuMntla kunye noMlambo waseYangtze ukuya kwiProjekthi yokuPhambuka koMlambo iHuaihe.
Iibhleyidi zeshaft kunye nempompo yokuqukuqela exutyiweyo zigqwethekile ngokwesithuba. Xa iimeko zokusebenza zempompo ziphambuka kwindawo yokuyila, umlinganiselo phakathi kwesantya esijikelezayo semida yangaphakathi nangaphandle yeeblades kutshatyalaliswa, okukhokelela ekuphakanyisweni okuveliswe ngamacangci (ii-airfoils) kwi-radii eyahlukileyo ayisalingani, ngaloo ndlela kubangela ukuba ukuhamba kwamanzi kwimpompo kube kuphazamiseka kwaye ilahleko yamanzi inyuke; okukhona ukude kwindawo yoyilo, kokukhona iqondo lokuqukuqela lokuqukuqela okukhulu kwamanzi kunye nelahleko enkulu yamanzi. Iimpompo ze-axial kunye ne-mixed flow pump zinentloko ephantsi kunye nommandla omxinwa osebenza kakhulu. Ukutshintsha kwentloko yabo yokusebenza kuya kubangela ukunciphisa okukhulu ekusebenzeni kwempompo. Ngoko ke, iimpompo ze-axial kunye ne-mixed flow flow pumps ngokubanzi azikwazi ukusebenzisa i-throttling, ukuguqula kunye nezinye iindlela zokulungelelanisa ukutshintsha ukusebenza kweemeko zokusebenza; ngelo xesha, ngenxa yokuba iindleko zokulawulwa kwesantya ziphezulu kakhulu, ukulawulwa kwesantya esiguquguqukayo kunqabile ukusetyenziswa ekusebenzeni kwangempela. Ekubeni iimpompo ze-axial kunye ne-mixed flow flow pump zinomzimba omkhulu we-hub, kulungele ukufakela ii-blade kunye ne-blade yokudibanisa izixhobo ezinokulungelelanisa i-angle. Ngoko ke, ukulungiswa kwemeko yokusebenza kweepompo ze-axial kunye ne-mixed flow pump ngokuqhelekileyo kuthatha ukulungiswa kwe-angle eguquguqukayo, enokwenza iimpompo ze-axial kunye ne-mixed flow pump zisebenze phantsi kwezona meko zilungileyo zokusebenza.
Xa ukunyuka kwamanqanaba omgangatho wamanzi anyukayo nasezantsi (oko kukuthi, intloko yenetha iyanda), i-angle yokubeka i-blade ihlengahlengiswa kwixabiso elincinci. Ngelixa kugcinwa ukusebenza kakuhle okuphezulu, izinga lokuhamba kwamanzi liyancitshiswa ngokufanelekileyo ukukhusela i-motor ekugqithiseni; xa umehluko wamanzi onyukayo kunye nasezantsi uyancipha (oko kukuthi, intloko yomnatha iyancipha), i-angle yokubeka i-blade ihlengahlengiswa kwixabiso elikhulu ukulayisha ngokupheleleyo i-motor kwaye ivumele impompo yamanzi ukuba impompe amanzi amaninzi. Ngamafutshane, ukusetyenziswa kwe-shaft kunye neepompo ezixubileyo ezinokuthi zitshintshe i-angle ye-blade zingenza ukuba zisebenze kwindawo efanelekileyo kakhulu yokusebenza, ukuphepha ukuvala ukunyanzeliswa kunye nokufezekisa ukusebenza kakuhle kunye nokupompa kwamanzi aphezulu.
Ukongezelela, xa iyunithi iqaliswa, i-angle yokubeka i-blade inokulungelelaniswa kwinqanaba elincinci, elinokunciphisa umthwalo wokuqala we-motor (malunga ne-1/3 ~ 2/3 yamandla alinganisiweyo); ngaphambi kokuvala, i-angle ye-blade inokulungiswa kwixabiso elincinci, elinokunciphisa isantya sokubuyela umva kunye nomthamo wamanzi wokuhamba kwamanzi kwimpompo ngexesha lokuvalwa, kunye nokunciphisa umonakalo wempembelelo yokuhamba kwamanzi kwisixhobo.
Ngamafutshane, isiphumo sohlengahlengiso lwe-engile ye-blade sibalulekile: ① Ukulungelelanisa i-engile kwixabiso elincinci kwenza kube lula ukuqala nokuvala; ② Ukulungelelanisa i-engile kwixabiso elikhulu kwandisa izinga lokuhamba; ③ Ukulungelelanisa i-engile kunokwenza iyunithi yempompo iqhube ngokwezoqoqosho. Ingabonwa ukuba i-angle angle adjuster ithatha indawo ebaluleke kakhulu ekusebenzeni nasekulawuleni izikhululo zokupompa eziphakathi kunye nezikhulu.
