Kodi "fyuluta ya mpweya" ndi chiyani?
Fyuluta ya mpweya ndi chipangizo chomwe chimagwira tinthu tating'onoting'ono pogwiritsa ntchito zinthu zosefera zomwe zili ndi mabowo ndikuyeretsa mpweya. Pambuyo poyeretsa mpweya, imatumizidwa m'nyumba kuti iwonetsetse kuti zipinda zoyera ndi kuyeretsa mpweya m'zipinda zonse zomwe zili ndi mpweya woziziritsa. Njira zosefera zomwe zikudziwika pano zimapangidwa makamaka ndi zotsatira zisanu: zotsatira zoletsa, zotsatira za inertial, zotsatira za kufalikira, mphamvu yokoka, ndi zotsatira za electrostatic.
Malinga ndi zofunikira pakugwiritsa ntchito mafakitale osiyanasiyana, zosefera za mpweya zitha kugawidwa m'magulu awiri: fyuluta yayikulu, fyuluta yapakatikati, fyuluta ya hepa ndi fyuluta ya ultra-hepa.
Kodi mungasankhe bwanji fyuluta ya mpweya moyenera?
01. Dziwani bwino momwe zosefera zimagwirira ntchito pamlingo uliwonse kutengera momwe ntchito ikuyendera.
Zosefera zoyambira ndi zapakatikati: Zimagwiritsidwa ntchito kwambiri poyeretsa mpweya ndi makina oziziritsira mpweya. Ntchito yawo yayikulu ndikuteteza zosefera zomwe zili pansi pa madzi ndi mbale yotenthetsera yoziziritsira pamwamba pa chipangizo choziziritsira mpweya kuti zisatsekeke ndikuwonjezera nthawi yawo yogwira ntchito.
Fyuluta ya Hepa/ultra-hepa: yoyenera kugwiritsidwa ntchito pazochitika zokhala ndi zofunikira kwambiri paukhondo, monga malo operekera mpweya woziziritsa mpweya m'malo ochitira masewera olimbitsa thupi opanda fumbi m'chipatala, kupanga magetsi, kupanga zida zolondola komanso mafakitale ena.
Kawirikawiri, fyuluta yotsirizira imatsimikizira momwe mpweya ulili woyera. Mafyuluta akumtunda pamlingo uliwonse amachita ntchito yoteteza kuti azitha kugwira ntchito nthawi yayitali.
Kugwira bwino ntchito kwa zosefera pa gawo lililonse kuyenera kukonzedwa bwino. Ngati mafotokozedwe a magwiridwe antchito a magawo awiri oyandikana a zosefera ndi osiyana kwambiri, gawo lapitalo silingathe kuteteza gawo lotsatira; ngati kusiyana pakati pa magawo awiriwa sikusiyana kwambiri, gawo lomalizali lidzakhala lolemetsa.
Kapangidwe koyenera ndi kakuti mukamagwiritsa ntchito gulu la "GMFEHU" la efficiency specification, ikani fyuluta yoyamba masitepe awiri mpaka anayi aliwonse.
Pamaso pa fyuluta ya hepa kumapeto kwa chipinda choyera, payenera kukhala fyuluta yokhala ndi mawonekedwe a mphamvu osachepera F8 kuti itetezedwe.
Kugwira ntchito kwa fyuluta yomaliza kuyenera kukhala kodalirika, magwiridwe antchito ndi kasinthidwe ka fyuluta yoyambirira kuyenera kukhala koyenera, ndipo kusamalira fyuluta yoyamba kuyenera kukhala kosavuta.
02. Yang'anani magawo akuluakulu a fyuluta
Kuchuluka kwa mpweya woyezedwa: Pa zosefera zomwe zili ndi kapangidwe kofanana ndi fyuluta yomweyi, pamene kukana komaliza kwatsimikizika, dera la fyuluta limawonjezeka ndi 50%, ndipo nthawi yogwiritsira ntchito fyuluta idzakulitsidwa ndi 70%-80%. Pamene dera la fyuluta liwirikiza kawiri, nthawi yogwiritsira ntchito fyulutayo idzakhala yotalika katatu kuposa yoyambayo.
Kukana koyamba ndi kukana komaliza kwa fyuluta: Fyuluta imapanga kukana kwa mpweya, ndipo kuchuluka kwa fumbi pa fyuluta kumawonjezeka ndi nthawi yogwiritsira ntchito. Pamene kukana kwa fyuluta kukukwera kufika pamtengo winawake, fyulutayo imachotsedwa.
Kukana kwa fyuluta yatsopano kumatchedwa "kukana koyamba", ndipo mtengo wokana womwe umagwirizana ndi nthawi yomwe fyulutayo yachotsedwa umatchedwa "kukana komaliza". Zitsanzo zina za fyuluta zimakhala ndi magawo a "kukana komaliza", ndipo mainjiniya oziziritsa mpweya amathanso kusintha chinthucho malinga ndi momwe zinthu zilili pamalopo. Mtengo wokana komaliza wa kapangidwe koyambirira. Nthawi zambiri, kukana komaliza kwa fyuluta yomwe imagwiritsidwa ntchito pamalopo ndi kuwirikiza kawiri kapena kana kuposa kukana koyambirira.
Kukana komaliza kovomerezeka (Pa)
G3-G4 (zosefera zoyambirira) 100-120
F5-F6 (fyuluta yapakati) 250-300
F7-F8 (fyuluta yapakatikati kwambiri) 300-400
F9-E11 (sub-hepa fyuluta) 400-450
H13-U17 (fyuluta ya hepa, fyuluta ya ultra-hepa) 400-600
Kuchita bwino kwa kusefa: "Kuchita bwino kwa kusefa" kwa fyuluta ya mpweya kumatanthauza chiŵerengero cha kuchuluka kwa fumbi lomwe lagwidwa ndi fyuluta ku kuchuluka kwa fumbi la mpweya woyambirira. Kudziwa momwe kusefa kumagwirira ntchito sikungasiyanitsidwe ndi njira yoyesera. Ngati fyuluta yomweyi yayesedwa pogwiritsa ntchito njira zosiyanasiyana zoyesera, kuchuluka kwa magwiridwe antchito komwe kwapezeka kudzakhala kosiyana. Chifukwa chake, popanda njira zoyesera, kuchita bwino kwa kusefa sikungatheke kukamba za.
Kutha kusunga fumbi: Kutha kusunga fumbi kwa fyuluta kumatanthauza kuchuluka kwa fumbi komwe kuloledwa kusungidwa mu fyuluta. Kuchuluka kwa fumbi kukapitirira mtengo uwu, kukana kwa fyuluta kudzawonjezeka ndipo mphamvu yosefera idzachepa. Chifukwa chake, nthawi zambiri zimanenedwa kuti mphamvu yosunga fumbi ya fyuluta imatanthauza kuchuluka kwa fumbi lomwe limasungidwa pamene kukana chifukwa cha kuchuluka kwa fumbi kufika pamtengo wodziwika (nthawi zambiri kawiri kukana koyambirira) pansi pa voliyumu inayake ya mpweya.
03. Yang'anirani mayeso a fyuluta
Pali njira zambiri zoyesera momwe zosefera zimagwirira ntchito: njira ya gravimetric, njira yowerengera fumbi mumlengalenga, njira yowerengera, kusanthula kwa photometer, njira yowerengera kusanthula, ndi zina zotero.
Kuwerengera Njira Yojambulira (Njira ya MPPS) Kukula kwa Tinthu Tomwe Timalowa Kwambiri
Njira ya MPPS pakadali pano ndiyo njira yodziwika bwino yoyesera zosefera za hepa padziko lonse lapansi, ndipo ndiyo njira yovuta kwambiri yoyesera zosefera za hepa.
Gwiritsani ntchito kauntala kuti mufufuze mosalekeza ndikuyang'ana pamwamba pa mpweya wonse wa fyuluta. Kauntalayo imapereka chiwerengero ndi kukula kwa tinthu ta fumbi pa mfundo iliyonse. Njirayi singathe kungoyesa kuchuluka kwa ntchito ya fyuluta yokha, komanso kuyerekeza mphamvu ya malo aliwonse.
