Ana kiransa turbomachinery don canja wurin makamashi zuwa ci gaba da gudana na ruwa ta hanyar aiki mai ƙarfi na ruwan wukake a kan mai juyawa mai jujjuya ko don haɓaka jujjuyawar ruwan wukake ta hanyar kuzari daga ruwa. A cikin turbomachinery, igiyoyi masu juyawa suna yin aiki mai kyau ko mara kyau akan ruwa, haɓakawa ko rage matsa lamba. Turbomachinery ya kasu kashi biyu manyan nau'ikan: daya shine injin aiki wanda daga gare shi ne ruwa ke ɗaukar iko don ƙara matsi ko kan ruwa, kamar fanfunan fanfuna da na'urorin iska; Wani kuma shi ne babban motsi, wanda ruwan ke faɗaɗawa, yana rage matsi, ko kuma kan ruwa ya samar da wuta, kamar injin tururi da injin turbin ruwa. Babban mai motsi ana kiransa turbine, kuma injin aiki ana kiransa injin ruwan ruwa.
Dangane da ka'idodin aiki daban-daban na fan, ana iya raba shi zuwa nau'in ruwa da nau'in girma, daga cikinsu ana iya raba nau'in ruwa zuwa kwararar axial, nau'in centrifugal da kwararar ruwa. Dangane da matsa lamba na fan, ana iya raba shi zuwa busa, compressor da injin iska. Ma'auni na masana'antar injin mu na yanzu JB/T2977-92 ya tanada: Mai fan yana nufin fanko wanda ƙofarsa shine daidaitaccen yanayin shigar iska, wanda matsatsin fitarwa (matsalar ma'auni) bai wuce 0.015MPa; Matsin fitarwa (matsalar ma'auni) tsakanin 0.015MPa da 0.2MPa ana kiransa mai hurawa; Matsin fitarwa (matsin ma'auni) wanda ya fi 0.2MPa ana kiransa compressor.
Babban sassa na abin hurawa su ne: volute, mai tarawa da impeller.
Mai tarawa zai iya jagorantar iskar gas zuwa magudanar ruwa, kuma yanayin kwararar mashin ɗin yana da garanti ta hanyar lissafi na mai tarawa. Akwai nau'ikan sifofin masu tarawa da yawa, musamman: ganga, mazugi, mazugi, baka, baka, arc mazugi da sauransu.
Impeller gabaɗaya yana da murfin dabaran, dabaran, ruwa, faifai faifai guda huɗu, tsarinsa galibi welded ne da haɗin kai. Bisa ga kanti impeller na daban-daban shigarwa kusurwoyi, za a iya raba zuwa radial, gaba da baya uku. Mai kunnawa shine mafi mahimmancin ɓangaren fan na centrifugal, wanda babban mai motsi ke motsa shi, shine zuciyar turinachinery centrifugal, wanda ke da alhakin tsarin watsa makamashin da aka kwatanta ta Euler equation. Gudun da ke cikin centrifugal impeller yana shafar jujjuyawar impeller da lanƙwan ƙasa kuma tare da raguwa, dawowa da al'amuran kwarara na biyu, ta yadda magudanar ruwa a cikin impeller ya zama mai rikitarwa sosai.

Ana amfani da ƙarar don tattara iskar gas da ke fitowa daga cikin injin daskarewa. A lokaci guda kuma, makamashin motsa jiki na iskar gas na iya jujjuya shi zuwa madaidaicin kuzarin iskar gas ta hanyar rage saurin iskar gas a matsakaici, kuma ana iya jagorantar iskar don barin tashar volut. A matsayin turbomachinery na ruwa, hanya ce mai matukar tasiri don haɓaka aiki da ingantaccen aiki na busa ta hanyar nazarin filin ta na ciki. Don fahimtar ainihin yanayin kwarara cikin centrifugal abin hurawa da haɓaka ƙirar impeller da volute don haɓaka aiki da inganci, malamai sun yi babban bincike na ka'idar, bincike na gwaji da ƙididdige ƙima na centrifugal impeller da volute.
