KODI LAMINAR FLOW HOOD NDI CHIYANI MUCHIPINDA CHOyera?

Laminar flow hood ndi chipangizo chomwe chimateteza wogwiritsa ntchito ku chinthucho. Cholinga chake chachikulu ndikupewa kuipitsidwa kwa mankhwalawa. Mfundo yogwira ntchito ya chipangizochi imachokera ku kayendedwe ka laminar airflow. Kupyolera mu chipangizo china chosefera, mpweya umayenda mopingasa pa liwiro linalake kupanga mpweya wopita pansi. Kuthamanga kwa mpweya kumeneku kuli ndi liwiro lofanana komanso lolunjika, lomwe lingathe kuthetsa tinthu tating'onoting'ono ndi tizilombo toyambitsa matenda mumlengalenga.

Laminar flow hood nthawi zambiri imakhala ndi mpweya wapamwamba komanso makina otulutsa pansi. Makina operekera mpweya amakoka mpweya kudzera pa fani, amasefa ndi fyuluta ya mpweya wa hepa, kenako ndikuitumiza ku laminar flow hood. Mu laminar flow hood, makina operekera mpweya amakonzedwa pansi kudzera m'mipata yopangira mpweya, zomwe zimapangitsa kuti mpweya ukhale wofanana ndi mpweya wopingasa. Dongosolo lotayira pansi limatulutsa zowononga ndi zinthu zina mu hood kudzera mu mpweya wotuluka kuti mkati mwa hood mukhale oyera.

Laminar flow hood ndi chipangizo cham'deralo chopangira mpweya wabwino chokhala ndi vertical unidirectional flow. Ukhondo wa mpweya m'dera lanulo ukhoza kufikira ISO 5 (kalasi 100) kapena malo aukhondo apamwamba. Mulingo waukhondo umadalira ntchito ya fyuluta ya hepa. Malinga ndi kapangidwe kake, ma laminar otaya ma hood amagawidwa kukhala mafani komanso opanda fan, mtundu wakutsogolo wakubwerera komanso mtundu wakumbuyo wakumbuyo; malinga ndi njira yokhazikitsira, amagawidwa kukhala ofukula (gawo) ndi mtundu wokweza. Zigawo zake zazikulu ndi monga chipolopolo, pre-filter, fan, hepa fyuluta, static pressure box ndi zothandizira zipangizo zamagetsi, zipangizo zodzitetezera, ndi zina zotero. Mpweya wa mpweya wa unidirectional flow hood ndi fan nthawi zambiri umatengedwa kuchokera ku chipinda choyera, kapena ukhoza kutengedwa kuchokera ku mezzanine yaukadaulo, koma kapangidwe kake ndi kosiyana, kotero chidwi chiyenera kulipidwa pamapangidwewo. Chophimba chopanda mpweya cha laminar chimapangidwa makamaka ndi fyuluta ya hepa ndi bokosi, ndipo mpweya wake wolowera umatengedwa kuchokera ku air-conditioning system yoyeretsa.

Kuonjezera apo, hood yotchedwa laminar flow hood sikuti imangogwira ntchito yaikulu yopewera kuipitsidwa kwa mankhwala, komanso imalekanitsa malo ogwirira ntchito kuchokera kumadera akunja, imalepheretsa ogwira ntchito kuti asasokonezedwe ndi zowonongeka zakunja, ndikuteteza chitetezo ndi thanzi la ogwira ntchito. M'mayesero ena omwe ali ndi zofunikira kwambiri pa malo ogwirira ntchito, angapereke malo abwino ogwirira ntchito kuti ateteze tizilombo toyambitsa matenda akunja kuti tisakhudze zotsatira zoyesera. Pa nthawi yomweyo, laminar flow hoods nthawi zambiri amagwiritsa ntchito zosefera hepa ndi zipangizo zosinthira mpweya mkati, zomwe zingapereke kutentha kokhazikika, chinyezi ndi kuthamanga kwa mpweya kuti zisungidwe nthawi zonse pamalo ogwirira ntchito.

Kawirikawiri, laminar flow hood ndi chipangizo chomwe chimagwiritsa ntchito mfundo ya mpweya wa laminar kuti igwiritse ntchito mpweya kudzera pa chipangizo cha fyuluta kuti chilengedwe chikhale choyera. Ili ndi ntchito zambiri m'magawo ambiri, kupereka malo otetezeka komanso aukhondo ogwira ntchito kwa ogwira ntchito ndi zinthu.
