Haisi chakavanzika chokuti munhu akaoma kumisa mukutsvaka kwake kunyaradzwa. Uye kuchena kwemhepo mauri kunotora basa rinokosha mukugadzirisa mamiriro ezvinhu akanaka mumba. Zvinosuruvarisa, mukati memahombekombe emukati medu makarongwa nenzira iyo isingagoni kupa mukana wakakodzera wekushandurwa kwemhepo. Uye kunyange kutenga mabhuku ekuchenesa mweya hakubatsiri nguva dzose. Mamiriro acho achabatsirwa nokutengwa kwechigadzirwa chakakosha chinobatsira masasa emhepo kufamba uye nekuvandudza zvakakurumidza- fan . Pamusoro pezvinhu zvekuisa nekushanda kwevashandi vepaRefal domestic, tichataura nhasi.
Ndechipi musiyano pakati pe fanal radial uye fan anxial?
Iko mureza we radial akarongwa sei uye chii chakasiyana nacho kubva kune axial fan? Sezvazvinozivikanwa, mumhepo inofungidzirwa mumhepo inotungamirwa nemajeko (makasi) akakomberedza mutsara mairi aya akabatanidzwa. Iko ndiko kuti, kufamba kwemhepo nemafungu emhepo kunowanikwa mundiro imwechete, uye mune imwe nzira. Kusiyana neaxial fans mumhepo dzinotarisa, kutungamirirwa kwemhepo kufamba mumhepo uye kubuda kwechikwata hakufanani - kubuda kwemhepo kunowanikwa pamakona akakwana kumhepo inopinda.
Chinhu chikuru chekushanda kwemafirimu emhepo inopisa, iyo inoratidzika seyendarira, panze yakafukidzwa nemaruva. Mabhanhire emuchina we radial anogona kukombomira mberi kana kumashure. Mufudzi ane mazamu akavhara kumashure anowedzera uye anoshandisa 25% mashoma simba, asi ane nhamba dzisina kukanganisa dzinoita kuti zvishandiswe pamigariro yemhuri isingadikanwi: inowedzera ruzha panguva yekushanda uye ine huwandu hukuru hwehuwandu.
Kuiswa kwevhidhiyo yepafari yepamba yekudzura
Pamusana pekugadzirwa kwavo, mafidi radial, anonzi centrifugal fans, anogona kukonzera kudzvinyirira kwakakwirira uye kufambisa mhepo kumhepo yakareba kupfuura iyo axial. Ndokusaka vateveri vemazuva ano vanowanzoshandiswa mumashamba emagetsi. Mumakamuri emumba, mafi ra radial anoshandiswa chete seashanti mashizha uye akaiswa mukati memhara. Muchiitiko ichi, munzvimbo iyo mota yemhepo inokwidziridzwa, mhepo inofanirwa kuchinja inofanirwa kuchinja mararamiro ayo kune imwe nzira yakarurama. Kuti kuderedze huwandu hwemashoko uye ruzha, vateereri vemazuva ano vanofanira kunge vakagadzirirwa kushamwaridzana kunokonzera kushandiswa panguva yekugadzira.
Kuti huti fanhu inogara kwenguva yakareba kwemakore akawanda isina kuparara, zvinotevera zvinofanirwa kusangana muimba iyo inoshandiswa:
- kutonhorera kwemweya hakufaniri kuva pamusoro pemadhigirii makumi matanhatu;
- Nhamba yezvinosvibisa zvinokonzerwa mumhepo haifaniri kudarika 1 gramu pa 1 cubic mita;
- Panofanira kunge pasina michina yakaoma uye michina inobhururuka mumhepo.
Kuenzaniswa kwemafirimu emhepo
Zvichienderana nemamiriro acho ezvinhu, kusiyanisa zvakasiyana-siyana zvemafero e radial (centrifugal):
- Mukufamba kwekufamba kwemhepo masasa:
- kushamwaridzana;
- kuneta.
- kudzvinyirirwa (kusvika pa1000 Pa);
- miviri yakasimba (1000-3000 Pa);
- kukanganiswa kukuru (3000-12000 Pa).
- kuruboshwe (mairi-maawa) kutenderera;
- kurudyi (kutaridzika) kutenderera.
Kazhinji kazhinji mumagadzirirwo emhepo mhepo uye air airing, uye
Zviratidzo zvemafaro emhepo
Pakusarudza mhando chaiyo yemufaro wepachimbwa wepamba anofunga nezvezviitiko zvinotevera:
- simba rekushandisa motokari;
- Kuita - chiyero chemhepo iyo fan inokwanisa kudarika iyo pachayo muchikamu chenguva;
- kudzvinyirirwa kwemhepo pachiteshi chema fan;
- Kusiyanisa kupesana pamusuo uye kubudiswa kweiyo fan;
- kuoma kwechimiro - girafu rinoratidza kuoma kunomiririra pane zvinoitwa nefi.
