NTCHITO NDI UBWINO WA FFU FAN FILTER UNIT

Mapulogalamu

FFU fan filter unit, yomwe nthawi zina imatchedwanso laminar flow hood, imatha kulumikizidwa ndikugwiritsidwa ntchito mwanjira yofanana ndipo imagwiritsidwa ntchito kwambiri m'chipinda choyera, benchi yogwirira ntchito yoyera, mizere yoyera yopangira, chipinda choyera chosonkhanitsidwa ndi chipinda choyera choyera.

Chida chosefera mafani cha FFU chili ndi zosefera zoyambira ndi za hepa ziwiri. Faniyo imayamwa mpweya kuchokera pamwamba pa chipangizo chosefera mafani ndikusefera kudzera mu zosefera zoyambira ndi za hepa.

Ubwino

1. Ndi yoyenera kwambiri kusonkhana m'mizere yopangira yoyera kwambiri. Ikhoza kukonzedwa ngati gawo limodzi malinga ndi zosowa za njira, kapena mayunitsi angapo akhoza kulumikizidwa motsatizana kuti apange mzere wolumikizira chipinda choyera cha kalasi 100.

2. Chida chosefera mafani cha FFU chimagwiritsa ntchito fani yakunja ya rotor centrifugal, yomwe imakhala ndi moyo wautali, phokoso lochepa, yosakonza, kugwedezeka pang'ono, komanso kusintha liwiro lopanda masitepe. Yoyenera kupeza malo oyera kwambiri m'malo osiyanasiyana. Imapereka mpweya wabwino kwambiri kuti chipinda choyera ndi malo ang'onoang'ono azikhala oyera m'malo osiyanasiyana komanso milingo yosiyanasiyana yaukhondo. Pomanga chipinda chatsopano choyera, kapena kukonzanso chipinda choyera, sichingowonjezera kuchuluka kwa ukhondo, kuchepetsa phokoso ndi kugwedezeka, komanso kuchepetsa mtengo kwambiri. Chosavuta kuyika ndi kusamalira, ndi gawo labwino kwambiri la malo oyera.

3. Kapangidwe ka chipolopolocho kamapangidwa ndi mbale yapamwamba kwambiri ya aluminiyamu-zinc, yomwe ndi yopepuka kulemera, yosagwira dzimbiri, yosagwira dzimbiri, komanso yokongola.

4. Ma FFU laminar flow hood amasakidwa ndikuyesedwa chimodzi ndi chimodzi malinga ndi US Federal Standard 209E ndi fumbi particle counter kuti zitsimikizire kuti ndi zabwino.
