FFU fan filter unit ndi chida chofunikira pa ntchito zoyeretsa chipinda. Ndi fyuluta yofunikira kwambiri yoperekera mpweya kuti chipinda choyera chisakhale ndi fumbi. Imafunikanso pa mipando yogwirira ntchito yoyera kwambiri komanso pa malo oyeretsera.
Ndi chitukuko cha chuma komanso kusintha kwa miyoyo ya anthu, anthu ali ndi zofunikira zapamwamba kwambiri pa khalidwe la zinthu. FFU imasankha khalidwe la zinthu kutengera ukadaulo wopanga ndi malo opangira zinthu, zomwe zimakakamiza opanga kuti atsatire ukadaulo wabwino wopanga zinthu.
Magawo omwe amagwiritsa ntchito zida zosefera mafani a FFU, makamaka zamagetsi, mankhwala, chakudya, bioengineering, zamankhwala, ndi ma laboratories, ali ndi zofunikira kwambiri pa malo opangira. Zimaphatikiza ukadaulo, zomangamanga, zokongoletsera, kupereka madzi ndi ngalande, kuyeretsa mpweya, HVAC ndi mpweya woziziritsa, kulamulira kokha ndi ukadaulo wina uliwonse. Zizindikiro zazikulu zaukadaulo zoyezera mtundu wa malo opangira m'mafakitale awa ndi monga kutentha, chinyezi, ukhondo, kuchuluka kwa mpweya, kuthamanga kwa mpweya mkati, ndi zina zotero.
Chifukwa chake, kuwongolera moyenera zizindikiro zosiyanasiyana zaukadaulo za malo opangira zinthu kuti zikwaniritse zofunikira pakupanga zinthu zapadera kwakhala imodzi mwa malo ofufuzira omwe alipo pakali pano paukadaulo wa zipinda zoyera. Kale m'ma 1960, chipinda choyamba choyera chamadzimadzi padziko lonse lapansi chinapangidwa. Kugwiritsa ntchito FFU kwayamba kuwonekera kuyambira pomwe idakhazikitsidwa.
1. Momwe njira yowongolera FFU ilili panopa
Pakadali pano, FFU nthawi zambiri imagwiritsa ntchito ma mota a AC okhala ndi liwiro la gawo limodzi, ma mota a EC okhala ndi liwiro la gawo limodzi. Pali ma voltage awiri amagetsi a FFU fan filter unit: 110V ndi 220V.
Njira zake zowongolera zimagawidwa m'magulu otsatirawa:
(1). Kulamulira ma switch a liwiro lambiri
(2). Kuwongolera liwiro losayenda pang'onopang'ono
(3). Kulamulira makompyuta
(4). Kulamulira kutali
Zotsatirazi ndi kusanthula kosavuta ndi kufananiza njira zinayi zowongolera zomwe zili pamwambapa:
2. FFU yowongolera ma switch ambiri
Dongosolo lowongolera ma switch ambiri limaphatikizapo switch yowongolera liwiro ndi switch yamagetsi yomwe imabwera ndi FFU. Popeza zigawo zowongolera zimaperekedwa ndi FFU ndipo zimagawidwa m'malo osiyanasiyana padenga la chipinda choyera, antchito ayenera kusintha FFU kudzera pa switch yosinthira pamalopo, zomwe zimakhala zovuta kwambiri kuziwongolera. Kuphatikiza apo, liwiro la mphepo losinthika la FFU limakhala ndi magawo ochepa. Pofuna kuthana ndi zinthu zovuta zoyendetsera FFU, kudzera mu kapangidwe ka mabwalo amagetsi, ma switch onse a FFU a liwiro lalikulu adayikidwa pakati ndikuyikidwa mu kabati pansi kuti agwire ntchito pakati. Komabe, mosasamala kanthu za mawonekedwe kapena pali zoletsa pakugwira ntchito. Ubwino wogwiritsa ntchito njira yowongolera ma switch ambiri ndikuwongolera kosavuta komanso mtengo wotsika, koma pali zolephera zambiri: monga kugwiritsa ntchito mphamvu zambiri, kulephera kusintha liwiro bwino, kusakhala ndi chizindikiro chobwezera, komanso kulephera kukwaniritsa kulamulira kwamagulu kosinthasintha, ndi zina zotero.
3. Kuwongolera kusintha kwa liwiro popanda masitepe
Poyerekeza ndi njira yowongolera ma switch ambiri, njira yowongolera ma switch opanda ma stepless ili ndi njira yowonjezera yowongolera ma speed opanda ma stepless, yomwe imapangitsa kuti liwiro la fan la FFU lizisinthasintha nthawi zonse, komanso imawononga mphamvu ya injini, zomwe zimapangitsa kuti mphamvu zake zigwiritsidwe ntchito kwambiri kuposa njira yowongolera ma switch ambiri.
- Kulamulira makompyuta
Njira yowongolera makompyuta nthawi zambiri imagwiritsa ntchito mota ya EC. Poyerekeza ndi njira ziwiri zapitazi, njira yowongolera makompyuta ili ndi ntchito zapamwamba izi:
(1). Pogwiritsa ntchito njira yolamulira yogawidwa, kuyang'anira ndi kuwongolera FFU pakati kumatha kuchitika mosavuta.
(2). Chigawo chimodzi, mayunitsi angapo ndi kugawa kwa FFU zitha kuchitika mosavuta.
(3). Dongosolo lowongolera lanzeru lili ndi ntchito zopulumutsa mphamvu.
(4). Chowongolera chakutali chosankha chingagwiritsidwe ntchito poyang'anira ndi kulamulira.
(5). Dongosolo lowongolera lili ndi mawonekedwe olumikizirana osungidwa omwe amatha kulumikizana ndi kompyuta kapena netiweki yolandirira kuti akwaniritse ntchito zolumikizirana ndi kuyang'anira kutali. Ubwino waukulu wowongolera ma mota a EC ndi: kuwongolera kosavuta komanso kuthamanga kwambiri. Koma njira yowongolera iyi ilinso ndi zolakwika zina zoopsa:
(6). Popeza ma mota a FFU saloledwa kukhala ndi maburashi m'chipinda choyera, ma mota onse a FFU amagwiritsa ntchito ma mota a EC opanda maburashi, ndipo vuto la kusintha kwa magetsi limathetsedwa ndi ma commutator amagetsi. Kufupika kwa moyo wa ma commutator amagetsi kumapangitsa kuti moyo wonse wa ntchito ya makina owongolera uchepe kwambiri.
(7). Dongosolo lonse ndi lokwera mtengo.
(8). Ndalama zokonzera pambuyo pake zimakhala zambiri.
5. Njira yowongolera kutali
Monga chowonjezera pa njira yowongolera makompyuta, njira yowongolera kutali ingagwiritsidwe ntchito kuwongolera FFU iliyonse, yomwe imawonjezera njira yowongolera makompyuta.
Mwachidule: njira ziwiri zoyambirira zowongolera zimagwiritsa ntchito mphamvu zambiri ndipo sizosavuta kuzilamulira; njira ziwiri zomaliza zowongolera zimakhala ndi nthawi yochepa komanso mtengo wotsika. Kodi pali njira yowongolera yomwe ingagwiritse ntchito mphamvu zochepa, kuwongolera kosavuta, moyo wotsimikizika wautumiki, komanso mtengo wotsika? Inde, imeneyo ndi njira yowongolera kompyuta pogwiritsa ntchito mota ya AC.
Poyerekeza ndi ma mota a EC, ma mota a AC ali ndi zabwino zambiri monga kapangidwe kosavuta, kukula kochepa, kupanga kosavuta, kugwira ntchito kodalirika, komanso mtengo wotsika. Popeza alibe mavuto osinthasintha, moyo wawo wogwirira ntchito ndi wautali kwambiri kuposa wa ma mota a EC. Kwa nthawi yayitali, chifukwa cha kusagwira bwino ntchito kwake polamulira liwiro, njira yowongolera liwiro yakhala ikugwiritsidwa ntchito ndi njira yowongolera liwiro la EC. Komabe, chifukwa cha kubuka ndi chitukuko cha zida zamagetsi zatsopano zamagetsi ndi ma circuits akuluakulu ophatikizidwa, komanso kubuka ndi kugwiritsa ntchito mosalekeza malingaliro atsopano owongolera, njira zowongolera za AC zakula pang'onopang'ono ndipo pamapeto pake zidzalowa m'malo mwa machitidwe owongolera liwiro la EC.
Mu njira yowongolera ya FFU AC, imagawidwa m'njira ziwiri zowongolera: njira yowongolera ma voltage ndi njira yowongolera ma frequency conversion. Njira yotchedwa njira yowongolera ma voltage ndikusintha liwiro la mota mwa kusintha mwachindunji ma voltage a stator ya mota. Zoyipa za njira yowongolera ma voltage ndi izi: kugwira ntchito kochepa panthawi yowongolera liwiro, kutentha kwambiri kwa mota pa liwiro lotsika, komanso kuchuluka kochepa kwa liwiro. Komabe, zoyipa za njira yowongolera ma voltage sizikudziwika bwino pa katundu wa mafani a FFU, ndipo pali zabwino zina zomwe zikuchitika pano:
(1). Ndondomeko yowongolera liwiro ndi yokhwima ndipo njira yowongolera liwiro ndi yokhazikika, zomwe zingatsimikizire kuti ikugwira ntchito mosalekeza popanda mavuto kwa nthawi yayitali.
(2). Yosavuta kugwiritsa ntchito komanso yotsika mtengo pamakina owongolera.
(3). Popeza katundu wa fan ya FFU ndi wopepuka kwambiri, kutentha kwa injini sikoopsa kwambiri pa liwiro lochepa.
(4). Njira yowongolera ma voltage ndi yoyenera kwambiri pa katundu wa fan. Popeza FFU fan duty curve ndi damping curve yapadera, liwiro la control likhoza kukhala lalikulu kwambiri. Chifukwa chake, mtsogolo, njira yowongolera ma voltage idzakhalanso njira yayikulu yowongolera liwiro.
