A na-ekewa Turbomachinery n'ime isi ụzọ abụọ: otu bụ igwe na-arụ ọrụ nke mmiri na-enweta ike iji mee ka isi nrụgide ma ọ bụ isi mmiri, dị ka nfuli vane na ventilashị; Nke ọzọ bụ isi ihe na-ebugharị, nke mmiri ahụ na-agbasawanye, na-ebelata nrụgide, ma ọ bụ isi mmiri na-emepụta ike, dị ka turbines na mmiri mmiri. A na-akpọ onye na-ebugharị ihe mbụ turbine, a na-akpọkwa igwe na-arụ ọrụ igwe mmiri agụba.
Dị ka ụkpụrụ dị iche iche na-arụ ọrụ nke onye fan ahụ si dị, enwere ike kewaa ya n'ụdị agụba na ụdị olu, n'etiti nke ụdị agụba nwere ike kewaa n'ime axial flow, ụdị centrifugal na ngwakọta agwakọta. Dị ka nrụgide nke fan ahụ si dị, enwere ike kewaa ya n'ime ikuku, compressor na ventilator. Ụkpụrụ ụlọ ọrụ anyị dị ugbu a JB / T2977-92 na-akọwa: Onye na-akwado ya na-ezo aka na onye ofufe nke ọnụ ụzọ ya bụ ọnọdụ ntinye ikuku ọkọlọtọ, nke nrụgide ọpụpụ (nrụgide nlele) bụ ihe na-erughị 0.015MPa; A na-akpọ nrụgide ntinye (nrụgide nlele) n'etiti 0.015MPa na 0.2MPa onye na-afụ ọkụ; Nrụpụta mpụta (nrụgide nlele) karịrị 0.2MPa ka a na-akpọ compressor.
Akụkụ ndị bụ isi nke onye na-afụ ọkụ bụ: volut, onye nchịkọta na impeller.
Onye na-anakọta nwere ike iduzi gas na impeller, na ọnọdụ ntinye ntinye nke impeller na-ekwe nkwa site na geometry nke onye nchịkọta. E nwere ọtụtụ ụdị onye na-anakọta ihe, tumadi: gbọmgbọm, cone, cone, arc, arc arc, arc cone na ndị ọzọ.
Impeller n'ozuzu nwere wheel mkpuchi, wheel, agụba, aro disk anọ components, ya Ọdịdị bụ tumadi welded na riveted njikọ. Dị ka impeller tinyekwa dị iche iche echichi akụkụ, nwere ike kewaa radial, n'ihu na azụ atọ. The impeller bụ akụkụ kacha mkpa nke centrifugal fan, nke onye isi na-ebugharị, bụ obi nke centrifugal turinachinery, na-ahụ maka usoro nnyefe ike nke Euler equation kọwara.

A na-ejikarị ụda olu na-anakọta gas na-esi na impeller pụta. N'otu oge ahụ, ike kinetic nke gas nwere ike gbanwee n'ime ike nrụgide static nke gas site n'ibelata ọsọ gas ahụ n'ụzọ dị nro, na gas nwere ike iduzi ka ọ hapụ volut. Dị ka mmiri turbomachinery, ọ bụ ụzọ dị irè iji melite arụmọrụ na ịrụ ọrụ nke ọma site n'ịmụ ihe ubi nke ime ya.
