ICentrifugal Slurry Slurry Flow in the Impoller

Lapho i-slurry isebenza uketshezi lapho isondo lijikeleza ngezinto eziphambili ndawonye, ​​ngasikhathi sinye futhi lisuka kwimposela ejikelezayo endizeni ngayinye. Uketshezi ngokuhamba okujikelezayo kwe-impeller kubizwa ngokuthi ukunyakaza okujikelezayo, inani lesisekelo libizwa ngokuthi ijubane le-peripheral, ukusetshenziswa okushoyo. Uketshezi ekujikelezeni impeller ngaphakathi flow flow lubizwa ngokuthi ukunyakaza okuhlobene, okuvezwa ngesivinini esikhulu, kuvezwe ku-velocity yomzimba ephelele, i-v imele velocity ngokuphelele lilingana nesivinini se-peripheral se-velocity velocity velocity kanye ne-W = = U + W ijubane le-peripheral le-impeller elishayela umugqa olinganiselwe we-tangent umugqa ojwayelekile, njengoba kukhonjisiwe ku-2-a); Inkombandlela ye-tangential ku-velocity ehlobene ne-blade ye-liquid, ukuqondiswa kwe-velocity ngokuphelele kwesimo se-liquid se-velocity ye-velocity ye-velocity ehlanganisiwe kanye ne-velocity ehlanganisiwe, njengoba kukhonjisiwe - Umdwebo 2. Ukuhamba kwe-Implemer kungamelwa ngokugqamile. Igrafu ekhombisa uketshezi ngesivinini se-impeller kanye nesiqondisi sokunyakaza ibizwa ngokuthi unxantathu weVelocity. Uketshezi ngaphakathi kwejubane le-impeller nganoma yisiphi isikhathi kunxantathu oboniswe kuMfanekiso 2-2. Kuqinile. Ngezikhathi ezithile,Umkhiqizi wePumpry PumpsIwusizo kakhulu yi-Inleller Inlet kanye ne-Outlet Fluid Flow State.

Lapho usayizi we-impoller waziwa, amapharamitha anikezwe, umlohlisi angenziwa ngonxantathu we-inlet kanye nokuphuma, ukuze uketshezi luhlaziywe ku-inleller ye-impeller kanye nokuphuma kwesimo sokugeleza. Ukuze wenze unxantathu we-velocity, i-velocity ephelele imvamisa ibolile ibe yizakhi ezimbili ze-orthogonal velocity: isivinini esime mpo se-velocity esokile, kuvame ukubizwa ngokuthi yi-axial velocity, emelelwa yi-VM; Enye inkomba iyahambisana nejubane elikuso lengxenye ye-velocity, elivame ukulibiza ngokuthi yi-velocity velocity esondelene, elishiwo nge-VM, kukhonjiswe kuMfanekiso 2-3.

Ku-velocity unxantathu, i-angle ye-velocity ephelele phakathi kwe-velocity esondelene ne-angle evunyelwe phakathi kwesivinini esiseduze se-velocity ehlobene ne-u phakathi kwe-β.
