I-impeller ibhekisa kwidiski yevili enamaphiko ahambayo. Kwimpompo ye-centrifugal, i-impeller ibhekisela kumzimba ojikelezayo onamacangca ahambisa amandla kulwelo.
Iincakuba zezigxininisi zempompo eziziisentimitha zidla ngokuba ziincakuba ezigobileyo ngasemva. Kukho iintlobo ezimbini zeencakuba: i-cylindrical kunye ne-twisted. Ukusetyenziswa kwee-blades eziphothiweyo kunokunciphisa umthwalo wee-blades, ukuphucula ukusebenza kwepompo ye-centrifugal, kunye nokuphucula amandla okulwa ne-cavitation, kodwa ukuvelisa kunzima kwaye ixabiso liphezulu.
Impompo ye-centrifugal yokucoca kunye neshishini lemichiza ifuna i-impeller ukuba iphoswe okanye i-welded ngokupheleleyo i-impeller edibeneyo. Uphuhliso lwe-welded impellers lusetyenziswa kakhulu kwiimpompo zekhemikhali ezikhethekileyo ze-centrifugal ezenziwe ngezinto zetsimbi ezineempawu zokuphosa (ezifana nentsimbi kunye ne-alloys yayo). Ukuchaneka kwejometri kunye nokugqitywa komphezulu we-welded impeller kungcono kunezo ze-impeller cast, enenzuzo ekuphuculeni ukusebenza kwepompo ye-centrifugal.
Ngokwendlela yokucubungula, i-impeller inokwahlulwa ibe yi-riveted type, uhlobo oludityanisiweyo kunye nodidi oludibeneyo. I-impeller eyenziwe ngokudibeneyo ibhekisa ikakhulu kwinkqubo yokuphosa echanekileyo kunye nezinye iinkqubo ezizodwa. Iinkqubo yokuphosa echanekileyoigcina zombini iiyure zomntu kunye nezinto eziphathekayo, kodwa ngenxa yesimo esiyinkimbinkimbi se-impeller kunye neemfuno eziphezulu zokucubungula, kunzima ukuqinisekisa ukuba ukuchithwa akunakho ukukhupha kunye nokungcola.
RMC Foundryinokuvelisa iintlobo ngeentlobo ze-impellers isebenzisa inkqubo yokuphosa echanekileyo (ukuphosa utyalo-mali) ngokunjaloCNC ukuchaneka machining. Sinokwenza izinto ezichaneke kakhulu, i-impellers-resistant-resistant kwi-austenitic stainless steel, i-duplex stainless steel, imvula eqinile eqinile, kunye ne-alloys esekwe kwi-nickel.
Okwangoku, iintlobo ezisisiseko ze-centrifugal pump impellers luhlobo lwe-flow channel (umsele omnye wokuhamba, umjelo wokuhamba kabini), uhlobo lwe-vane (uhlobo oluvaliweyo, uhlobo oluvulekileyo), uhlobo lwe-spiral centrifugal kunye nohlobo lwe-swirl.
1. I-Channel Type Impeller
I-impeller yomjelo wokuhamba ngumjelo ogobileyo ukusuka kwindawo yokungena ukuya kwindawo yokuphuma. Olu hlobo lwe-impeller lufanelekile ukuhambisa ulwelo oluqulethe amasuntswana amakhulu okungcola okanye imicu emide. Ngenxa yokuba olu hlobo lwe-impeller luneempawu ezintle zokulwa nokuvala. Kodwa ukungonakali kwakhe kukuba ukusebenza kwe-anti-cavitation kubuthathaka kunezinye iifom.
2. Vane Impeller
I-semi-open and open impellers kwi-vane impeller kulula ukuyiphosa, kwaye kulula ukuyigcina kunye nokucoca ukungcola okuvaliweyo kwinkqubo yokuhambisa. Nangona kunjalo, ukungonakali kwayo kukuba i-gap phakathi kodonga lwangaphakathi lwamanzi agxininisiweyo kunye ne-blade phantsi kwe-abrasion ye-particles eqinile iyanda ngexesha lenkqubo yokuthutha, okunciphisa ukusebenza kakuhle kwempompo, kunye nokuzinza kwemeko yokuhamba kwamanzi. kumjelo wokuhamba utshatyalalisiwe ngenxa yokwanda kwesithuba. , yenza i-vibrate yepompo, olu hlobo lwe-impeller alulula ukuthutha i-medium equkethe amaqhekeza amakhulu kunye nemicu emide. I-impeller evaliweyo inokusebenza okuphezulu kwaye inokuhamba kakuhle ixesha elide. I-axial thrust yepompo incinci, kodwa i-impeller evaliweyo ilula ukulimaza, kwaye akulula ukuthutha i-media media equkethe iinqununu ezinkulu okanye iifiber ezide.
3. I-Spiral Centrifugal Impeller
I-Spiral centrifugal impellers zineencakuba ezijijekileyo ezisuka nge-axially ukusuka kwizibuko lokufunxa kwi-tapered hub body. I-liquid ehambisayo ayiyi kubetha nayiphi na inxalenye yepompo xa igeleza ngamacangci, ngoko akukho monakalo kwimpompo, kwaye ngelo xesha, ayinakonakalisa i-liquid ehambisayo. Ngenxa yokuqhubela phambili kwe-screw, iinqununu ezimisiweyo zinokugqithiswa okunamandla, ngoko olu hlobo luyamkelwa. Iimpompo ze-impeller zifanelekile ukupompa imidiya equkethe iinqununu ezinkulu kunye neentambo ezide.
4. I-Swirl Impeller
I-impeller ejikelezayo iyonke okanye inxalenye ye-impeller ebuyiselwa kumjelo wokuhamba wegumbi elixinzelelekileyo lamanzi, elinomsebenzi omhle wokuchasana nokuvala. Iingqungquthela zihamba kwindawo yoxinzelelo lwamanzi phantsi kwempembelelo ye-vortex eyenziwa ngokujikeleza kwe-impeller, kwaye ukuhamba kweengqungquthela ezimisiweyo akuvelisi amandla, kwaye utshintshise amandla kunye ne-liquid kwi-flow channel. Ngethuba lenkqubo yokuhamba, iinqununu ezimisiweyo okanye iifiber ezide aziqhagamshelani neentambo ezigugileyo, ii-blades zigqithisekile, kwaye i-gap ayikhuliswanga ngenxa ye-abrasion. Kufanelekile ukupompa imidiya equlethe iinqununu ezinkulu kunye neentambo ezide.
I-vane impellers ezisetyenziswa kwiimpompo ze-centrifugal zinokwahlulwa zibe ziintlobo ezine: (a) uhlobo oluvaliweyo; (b) uhlobo oluvulekileyo lwangaphambili; (c) uhlobo olungasemva oluvulekileyo; (d) uhlobo oluvulekileyo
1. I-impeller evaliweyo
I-impeller evaliweyo iqulethwe ngamacwecwe kunye namacwecwe angaphambili nasemva. I-impeller evaliweyo inokusebenza okuphezulu kwaye kunzima ukuyenza, kwaye isetyenziswa kakhulu kwiimpompo ze-centrifugal. Kufanelekile ukuhambisa i-liquids ecocekileyo kunye ne-viscosity ephantsi kwaye akukho maqhekeza, njengamanzi acocekileyo kunye nezisombululo.
2. Semi-open impeller
I-impeller ye-semi-open ngokubanzi inezakhiwo ezibini: enye luhlobo olungaphambili lwe-semi-open, oluqulunqwe yipleyiti yokugubungela yangasemva kunye neencakuba. Ukusebenza kwe-impeller kwesi sakhiwo siphantsi, kwaye indandatho yokutywina kunye ne-adjustable clearance iyadingeka ukuze kuphuculwe ukusebenza kakuhle; enye yipleyiti yokugquma yangasemva kunye nencakuba. Uhlobo oluvulekileyo lwe-semi-open luquka ipleyiti yekhava yangaphambili kunye ne-blade. Ekubeni umsesane wokutywina ofanayo kunye ne-impeller evaliweyo ingasetyenziswa, ukusebenza kakuhle kuyafana naleyo ye-impeller evaliweyo, kwaye i-blade nayo inesitywina (i-back blade okanye i-impeller encedisayo) ngaphezu kokuhambisa ulwelo. isiphumo. I-impeller semi-open ilungele ukuhambisa ulwelo oluqulathe izinto eziqinileyo ezifana namasuntswana aqinileyo kunye nemicu. I-semi-open impeller ayinzima kakhulu ukuyenza, iphantsi kweendleko, kwaye inokwazi ukuziqhelanisa.
3. Vula i-impeller
I-impeller evulekileyo inamacangca kuphela kunye ne-blade yokuqinisa iimbambo, kwaye akukho nto i-impeller enamacwecwe angaphambili nangemuva. I-impeller inokusebenza okuphantsi kunye nezicelo ezincinci, kwaye isetyenziselwa ukuthutha ulwelo olune-viscosity ephezulu kunye nolwelo oluludaka.
