Lapho i-Slurry isebenza uketshezi lapho isondo lizungeza izici eziyinhloko ndawonye , ngesikhathi esifanayo futhi kusukela ku-impeller ejikelezayo endizeni ngayinye.I-Liquid ene-rotational movement of the impeller ibizwa ngokuthi i-circular motion, izinga lesisekelo libizwa ngesivinini se-peripheral, sebenzisa u-u said.Uketshezi olusuka ku-impeller ejikelezayo ngaphakathi kokugeleza kwangaphandle kubizwa ngokuthi ukunyakaza kwesihlobo , isivinini saso esihlobene nesivinini , esivezwa ngoketshezi lwe-W oluhlobene nokunyakaza komzimba wephampu okwaziwa ngokuthi ukunyakaza okuphelele , isivinini sawo sibizwa ngokuthi isivinini esiphelele , kanti u-V umele isivinini esiphelele esingu-V futhi u-u ilingana nesivinini se-peripheral ye-vector ye-velocity ehlobene kanye ne-W, okungukuthi, V = u + W Ijubane le-peripheral le-impeller elishayela umugqa we-tangent ojikelezayo we-liquid , njengoba kuboniswe ku-2-1a);isiqondiso se-tangential ku-blade yesivinini esihlobene soketshezi , isiqondiso sesivinini esiphelele sejubane le-liquid ye-circumferential yejubane elihlanganisiwe nesivinini esihlobene , njengoba kubonisiwe - Umfanekiso 2. Ukunyakaza koketshezi ngaphakathi kwe-impeller kungamelwa ngemifanekiso.Igrafu ebonisa uketshezi ngesivinini se-impeller kanye nendawo yokunyakaza ibizwa ngokuthi unxantathu wesivinini .Uketshezi ngaphakathi kwejubane le-impeller kunoma iyiphi indawo kunxantathu oboniswe kuMfanekiso 2-2.Okuqinile .Kwesinye isikhathi,umkhiqizi wepompo ye-slurryokuwusizo kakhulu isimo sokugeleza kwe-impeller kanye ne-outlet fluid.
Uma usayizi we-impeller waziwa , imingcele enikeziwe , i-impeller ingenziwa ngonxantathu we-inlet kanye ne-outlet velocity , ukuze uketshezi luhlaziywe endaweni yokufaka i-impeller kanye nokuphuma kwesimo sokugeleza.Ukuze kwenziwe unxantathu wesivinini , isivinini esiphelele sivamise ukubola sibe izingxenye ezimbili ze-orthogonal velocity : eyodwa isivinini esime mpo sesivinini esiyindilinga , ngokuvamile sibizwa ngokuthi i-axial velocity, emelelwa i-Vm;esinye isiqondiso sihambisana nesivinini esiyisiyingi sengxenye yesivinini , ngokuvamile esibizwa ngokuthi ingxenye ye-circumferential velocity , ne- Vm eshiwo , eboniswe kuMfanekiso 2-3 .
Kunxantathu wesivinini , i-engeli ye-absolute velocity V phakathi kwe-velocity ye-circumferential u-u ene-engeli eshiwo phakathi kwesivinini esiyisiyingi sesivinini esihlobene w imelelwa ngu-u phakathi kuka-β.
