KUYINI I-LAMINAR FLOW HOOD EGUMBINI ELIHLANZEKILE?

I-laminar flow hood iyithuluzi elivikela umqhubi kumkhiqizo. Inhloso yalo eyinhloko ukugwema ukungcoliswa komkhiqizo. Isimiso sokusebenza sale divayisi sisekelwe ekuhambeni komoya we-laminar. Ngedivayisi ethile yokuhlunga, umoya ugeleza ngokuvundlile ngesivinini esithile ukuze wakhe umoya owehlayo. Lokhu kugeleza komoya kunesivinini esifanayo kanye nesiqondiso esifanayo, esingasusa ngempumelelo izinhlayiya namagciwane emoyeni.

I-laminar flow hood ivame ukuba nomoya ophezulu kanye nohlelo lokukhipha umoya oluphansi. Uhlelo lokunikeza umoya ludonsa umoya ngefeni, luwuhlunge ngesihlungi somoya se-hepa, bese luwuthumela ku-laminar flow hood. Ku-laminar flow hood, uhlelo lokunikeza umoya luhlelwe phansi ngokusebenzisa izikhala zokunikeza umoya eziklanywe ngokukhethekile, okwenza umoya ube nesimo esifanayo sokugeleza komoya ovundlile. Uhlelo lokukhipha umoya oluphansi lukhipha ukungcola kanye nezinhlayiya eziku-hood nge-outlet yomoya ukuze kugcinwe ingaphakathi le-hood lihlanzekile.

I-laminar flow hood iyidivayisi yokunikeza umoya ohlanzekile yendawo enokuhamba okuqondile okuqondile. Ukuhlanzeka komoya endaweni kungafinyelela ku-ISO 5 (isigaba 100) noma ngaphezulu endaweni ehlanzekile. Izinga lokuhlanzeka lincike ekusebenzeni kwesihlungi se-hepa. Ngokwesakhiwo, ama-laminar flow hood ahlukaniswe abe yi-fan kanye ne-fanless, uhlobo lomoya obuyayo ngaphambili kanye nohlobo lomoya obuyayo ngemuva; ngokwendlela yokufaka, ahlukaniswe abe uhlobo oluqondile (ikholomu) kanye nohlobo lokuphakamisa. Izingxenye zayo eziyisisekelo zifaka igobolondo, isihlungi sangaphambi kwesikhathi, ifeni, isihlungi se-hepa, ibhokisi lokucindezela elingaguquki kanye nezinto zikagesi ezisekelayo, amadivayisi okulawula okuzenzakalelayo, njll. Ukungena komoya kwe-unidirectional flow hood enefeni ngokuvamile kuthathwa egumbini elihlanzekile, noma kungathathwa ku-mezzanine yobuchwepheshe, kodwa isakhiwo sayo sihlukile, ngakho-ke kufanele kunakwe umklamo. I-laminar flow hood engenafeni yakhiwe kakhulu isihlungi se-hepa kanye nebhokisi, kanti umoya wayo ongenayo uthathwa ohlelweni lokupholisa umoya oluhlanzekile.

Ngaphezu kwalokho, i-laminar flow hood ayigcini nje ngokudlala indima eyinhloko yokugwema ukungcola komkhiqizo, kodwa futhi ihlukanisa indawo yokusebenza nemvelo yangaphandle, ivimbele abaqhubi ukuthi bangahlaselwa ukungcola kwangaphandle, futhi ivikele ukuphepha nempilo yabasebenzi. Kwezinye izivivinyo ezinezidingo eziphezulu kakhulu endaweni yokusebenza, ingahlinzeka ngendawo yokusebenza ehlanzekile ukuvimbela amagciwane angaphandle ukuthinta imiphumela yokuhlola. Ngesikhathi esifanayo, ama-laminar flow hood avame ukusebenzisa izihlungi ze-hepa namadivayisi okulungisa ukugeleza komoya ngaphakathi, okunganikeza izinga lokushisa elizinzile, umswakama kanye nesivinini sokugeleza komoya ukugcina indawo eqhubekayo endaweni yokusebenza.

Ngokuvamile, i-laminar flow hood iyithuluzi elisebenzisa isimiso sokugeleza komoya we-laminar ukucubungula umoya ngedivayisi yokuhlunga ukuze kugcinwe indawo ihlanzekile. Inezinhlelo zokusebenza eziningi emikhakheni eminingi, inikeza indawo yokusebenza ephephile nehlanzekile yabaqhubi kanye nemikhiqizo.
