Tahi turai. Ko te parau tumu o te mahi me te whānui

E hangaia mātanga pūnaha ventilation me te whāhauhau tango ki ngā āhuatanga maha pūkete. titau tāutanga muri aro motuhake: me waiho aerodynamics rangi, hatete, silencers, diffusers, grilles me vaolo i wahi, me nga pā me whāhauhau - i te kaha e tika ana.

Fan, turai axial ranei, te tikanga e taea te huaina te ngakau o te pūnaha, i roto i te meka pana reira te rangi i roto i te pūnaha iaia - mahani i roto i te aronga e hiahiatia ana. Ahakoa te meka e hiahiatia taua wae ki te mahi i te taua mahi - takoha kaupapa rangi, ia o ratou kua he hoahoa motuhake.

Te tahi turai. Ko te parau tumu pūrere o te mahi me te āhuatanga

Kei tēnei taputapu o te wira mahi, i titia nei te i runga i te take motuhake, te kokoru me rere putorino, me te whare tōrino. Air (hau nuku-) riro maha, me te tomo te mau pu te whare tahi tītaka matatahi wira. Ko te kupu i reira ko te tauiraa i roto i te ahunga o te rere o te hau (hau) i te whakarara raina tika tonu ki te tuaka, riro te reira toropā. Next, mahi kaha turai propels te rangi i roto i te kohao motuhake i roto i te whare.

Kua riro taua āhuatanga o tenei kōwae he take mo tona ingoa - i te tahi turai, he reira toropā. kua riro te taputapu whakawhetai ki tona tinana, tōrino-āhua - tetahi atu "ingoa" - te koko.

Huringa o te impeller i roto i te mea powhiriwhiri taua kia matau, ki maui ranei. Tau o matatahi pānga te momo me te whakaaro o te taputapu. He he kotahi arai: i roto i nei ara e piko ratou nga matatahi (whakamua hoki ranei) - i roto i ētahi wā, he reira o faufaa taketake. Hei tauira, he mea powhiriwhiri turai whakaratohia ki matatahi niao ki whakamuri, ka taea e whakaora ake ki te 20% pūngao, me ka te kikī whakaaetia i runga i te kohi rangi.

Whakamua matatahi piko, i tahuri, ka taea e whakaiti i te diameter o te wira ki te e kua piri ratou, a i runga i, te tahi ano e taea e atu kiato. iti iti tere, me te taumata haruru te: Ko tētahi atu painga.

Ka taea te whakamahi pūrere tahi turai i roto i te pūnaha takoha tangohanga me wharekai horoi kākahu, metallurgical me te matū ahumahi, refineries hinu. I roto i tenei take, mōhio e ki te whakamahere koe i runga i te neke ngā ma, e kore e poke ki poke hau kino, he reira nui ki "ngata" hanga o waro maitai. I roto i te wā i reira e kitea hau taikaha, whakamahia te taputapu e ki te konumohe koranu casing rino maka ranei. I roto i ngā tipu i reira i reira he he hiahia i roto i te rangi wero kei roto poke pukuriri hau kohu ranei, he mea tika ki te tāuta pā motuhake. Ratou āhuatanga motuhake e te wahi i roto rawa, i roto i nei e rere i te rangi kino (impeller ki matatahi, he casing, he kakau) hanga o alloys maitai waikawa-ātete, kirihou me te konumohe. Ko reira kitea e te mea kia taputapu motuhake, te pūrere ventilation pērā i te mea powhiriwhiri turai, ka nui ake hoki i roto i te paerewa o te waro maitai tona utu.
