I-impeller ibhekisela kwidiski yesondo enama-blade ahambayo. Kupompo ye-centrifugal, i-impeller ibhekisela emzimbeni ojikelezayo onama-blade adlulisela amandla oketshezini.
Ama-blades we-centrifugal pump impellers ngokuvamile ama-blade agobele emuva. Kunezinhlobo ezimbili zama-blades: i-cylindrical ne-twisted. Ukusetshenziswa kwama-blade asontekile kunganciphisa umthwalo wama-blades, kuthuthukise ukusebenza kwepompo ye-centrifugal, futhi kuthuthukise ikhono lokulwa ne-cavitation, kodwa ukukhiqiza kunzima futhi izindleko ziphezulu.
Iphampu ye-centrifugal yokucwenga kanye nemboni yamakhemikhali idinga ukuthi i-impeller iphonswe noma i-impeller ehlanganiswe ngokugcwele. Ukuthuthukiswa kwama-impellers ashiselwe ikakhulukazi asetshenziselwa amaphampu amakhemikhali akhethekile e-centrifugal enziwe ngezinto zensimbi ezinezakhiwo ezimbi zokuphonsa (njengensimbi nama-alloys ayo). Ukunemba kwejometri kanye nokuqedwa kwe-surface ye-impeller eshiselwe kungcono kunaleyo ye-cast cast, enenzuzo ukuthuthukisa ukusebenza kahle kwepompo ye-centrifugal.
Ngokwendlela yokucubungula, i-impeller ingahlukaniswa ngohlobo lwe-riveted, uhlobo olushiselwe kanye nohlobo olubalulekile. I-impeller eyakhiwe ngokuhlangene ikakhulukazi ibhekisela enqubweni yokusakaza enembayo nezinye izinqubo ezikhethekile. Iukunemba inqubo yokulingisaisindisa kokubili amahora womuntu kanye nezinto zokwakha, kodwa ngenxa yesimo esiyinkimbinkimbi se-impeller kanye nezidingo eziphezulu zokucubungula, kunzima ukuqinisekisa ukuthi ama-castings awanawo ama-pores nokungcola.
I-RMC Foundryingakwazi ukukhiqiza izinhlobo ezahlukene zama-impeller isebenzisa inqubo yokusakaza enembayo (i-investment casting) kanyeCNC ukunemba machining. Singakwazi ukukhiqiza ama-impeller anemba okuphezulu, ukumelana nokugqwala kusuka ku-austenitic stainless steel, i-duplex stainless steel, imvula eqinile, insimbi engagqwali eqinile, nama-alloys asekelwe ku-nickel.
Njengamanje, izinhlobo eziyisisekelo ze-centrifugal pump impellers ziwuhlobo lwesiteshi sokugeleza (isiteshi sokugeleza esisodwa, isiteshi sokugeleza kabili), uhlobo lwe-vane (uhlobo oluvaliwe, uhlobo oluvulekile), uhlobo lwe-spiral centrifugal kanye nohlobo lwe-swirl.
1. I-Impeller Yohlobo Lwesiteshi
I-impeller yesiteshi sokugeleza iyishaneli yokugeleza egobile ukusuka endaweni engenayo ukuya endaweni yokuphuma. Lolu hlobo lwe-impeller lufaneleka ukudlulisa uketshezi oluqukethe izinhlayiya ezinkulu zokungcola noma imicu emide. Ngoba lolu hlobo lwe-impeller lunezinto ezinhle kakhulu zokulwa nokuvala. Kodwa ukungalungi kwakhe ukuthi ukusebenza kwe-anti-cavitation kubuthakathaka kunezinye izinhlobo.
2. I-Vane Impeller
I-semi-open futhi evulekile impeller ku-vane impeller kulula ukuyiphonsa, futhi kulula ukuyigcina nokuhlanza ukungcola okuvinjiwe ohlelweni lokudlulisa. Kodwa-ke, ukungahambi kahle kwayo ukuthi igebe phakathi kodonga lwangaphakathi lwamanzi acindezelwe kanye ne-blade ngaphansi kokuhuzuka kwezinhlayiya eziqinile landa phakathi nenqubo yokuthutha, okunciphisa ukusebenza kahle kwepompo, nokuzinza kwesimo sokugeleza kwe-liquid. emseleni wokugeleza konakala ngenxa yokwanda kwegebe. , yenza ipompo idlidlize, lolu hlobo lwe-impeller akulula ukuthutha okuphakathi okuqukethe izinhlayiya ezinkulu nemicu ende. I-impeller evaliwe inokusebenza kahle okuphezulu futhi ingasebenza kahle isikhathi eside. I-axial thrust yepompo incane, kodwa i-impeller evaliwe kulula ukuyilimaza, futhi akulula ukuthutha imidiya yemfucumfucu equkethe izinhlayiya ezinkulu noma imicu ende.
3. I-Spiral Centrifugal Impeller
Ama-spiral centrifugal impeller anezinsimbi ezisontekile ezinwebeka nge-axially ukusuka embobeni yokumunca emzimbeni wehabhu ocijile. I-liquid edlulisiwe ngeke ishaye noma iyiphi ingxenye yepompo lapho igeleza ngama-blades, ngakho-ke akukho monakalo epompo, futhi ngesikhathi esifanayo, ayibhubhisi uketshezi oludlulisiwe. Ngenxa ye-propulsion of screw, izinhlayiya ezimisiwe zinokudlula okuqinile, ngakho lolu hlobo luyamukelwa. Amaphampu e-impeller afanele ukupompa imidiya equkethe izinhlayiya ezinkulu nemicu ende.
4. I-Swirl Impeller
I-swirling impeller yonke noma ingxenye ye-impeller ehlehliswa kumzila wokugeleza wekamelo lamanzi elicindezelweyo, elinomsebenzi omuhle wokulwa nokuvala. Izinhlayiya zigeleza ekamelweni lokucindezela kwamanzi ngaphansi komfutho we-vortex owenziwe ukujikeleza kwe-impeller, futhi ukunyakaza kwezinhlayiya ezimisiwe akukhiqizi amandla, futhi ukushintshanisa amandla nge-liquid esiteshini sokugeleza. Phakathi nenqubo yokugeleza, izinhlayiya ezimisiwe noma izintambo ezinde azixhumani nama-blade agugile, ama-blades agugile kakhulu, futhi igebe alikhuliswanga ngenxa yokulimala. Ifanele ukupompa imidiya equkethe izinhlayiya ezinkulu nemicu ende.
Ama-vane impeller asetshenziswa kumaphampu amaphakathi angahlukaniswa abe amafomu amane: (a) uhlobo oluvaliwe; (b) uhlobo oluvulekile ngaphambili; (c) uhlobo lwangemuva oluvulekile phakathi; (d) uhlobo oluvulekile
1. I-impeller evaliwe
I-impeller evaliwe iqukethe ama-blades namapuleti ekhava angaphambili nangemuva. I-impeller evaliwe inokusebenza okuphezulu futhi kunzima ukuyikhiqiza, futhi isetshenziswa kakhulu kumaphampu we-centrifugal. Ilungele ukudlulisa uketshezi oluhlanzekile olune-viscosity ephansi futhi azikho izinhlayiya, ezifana namanzi ahlanzekile nezisombululo.
2. I-semi-open impeller
I-semi-open impeller ngokuvamile inezakhiwo ezimbili: enye iwuhlobo olungaphambili oluvulekile kancane, olwakhiwe ipuleti lekhava elingemuva kanye nezindwani. Ukusebenza kahle kwe-impeller kwalesi sakhiwo kuphansi, futhi indandatho yokuvala enemvume eguquguqukayo iyadingeka ukuze kuthuthukiswe ukusebenza kahle; enye yi-cover plate yangemuva kanye ne-blade. Uhlobo oluvulekile luhlanganisa ipuleti lekhava yangaphambili kanye nensingo. Njengoba indandatho yokuvala efanayo ne-impeller evaliwe ingasetshenziswa, ukusebenza kahle ngokuyisisekelo kuyafana nalokhu kwe-impeller evaliwe, futhi i-blade nayo inophawu (i-back blade noma i-axiliary impeller) seal ngaphezu kokudlulisa uketshezi. umphumela. I-semi-open impeller ifanele ukudlulisa uketshezi oluqukethe izinto eziqinile ezimisiwe njengezinhlayiya eziqinile nemicu. I-semi-open impeller ayinzima kangako ukuyikhiqiza, iphansi ngezindleko, futhi inokuvumelana nezimo okuqinile.
3. Vula i-impeller
I-impeller evulekile inama-blade kanye nezimbambo zokuqinisa i-blade, futhi ayikho i-impeller enamapuleti ekhava angaphambili nangemuva. I-impeller inokusebenza okuphansi nokusebenza okuncane, futhi isetshenziselwa ukuthutha uketshezi olune-viscosity ephezulu kanye ne-slurry liquids.
