1. Chiyambi cha fyuluta ya hepa
Monga tonse tikudziwa, makampani opanga mankhwala ali ndi zofunikira kwambiri pa ukhondo ndi chitetezo. Ngati pali fumbi mufakitale, lingayambitse kuipitsa, kuwonongeka kwa thanzi komanso kuphulika kwa zinthu. Chifukwa chake, kugwiritsa ntchito zosefera za hepa ndikofunikira kwambiri. Kodi miyezo yogwiritsira ntchito zosefera za hepa, nthawi yosinthira, magawo osinthira ndi zizindikiro ndi ziti? Kodi malo opangira mankhwala omwe ali ndi zofunikira paukhondo wapamwamba ayenera kusankha bwanji zosefera za hepa? Mumakampani opanga mankhwala, zosefera za hepa ndi zosefera zomaliza zomwe zimagwiritsidwa ntchito pochiza ndi kusefa mpweya m'malo opangira. Kupanga aseptic kumafuna kugwiritsa ntchito zosefera za hepa mokakamiza, ndipo kupanga mitundu yolimba ndi yolimba nthawi zina kumagwiritsidwa ntchito. Chipinda choyeretsera mankhwala chimakhala chosiyana ndi zipinda zina zoyeretsera zamafakitale. Kusiyana kwake ndikuti popanga zokonzekera ndi zopangira zopanda septic, ndikofunikira osati kungoyang'anira tinthu tomwe tayikidwa mumlengalenga, komanso kuwongolera kuchuluka kwa tizilombo toyambitsa matenda. Chifukwa chake, makina oziziritsira mpweya mufakitale ya mankhwala alinso ndi njira zoyeretsera, zoyeretsera, zophera tizilombo ndi njira zina zowongolera tizilombo toyambitsa matenda mkati mwa malamulo oyenera. Fyuluta ya mpweya imagwiritsa ntchito fyuluta yokhala ndi mabowo kuti igwire fumbi kuchokera mu mpweya, kuyeretsa mpweya, ndikuyeretsa mpweya wafumbi ndikutumiza mchipindamo kuti zitsimikizire kuti mpweya uli bwino mchipindamo. Pa malo ochitira mankhwala omwe ali ndi zofunikira zapamwamba, ma fyuluta a hepa a gel seal nthawi zambiri amagwiritsidwa ntchito kusefa. Ma fyuluta a hepa a gel seal amagwiritsidwa ntchito kwambiri kuti agwire tinthu tosakwana 0.3μm. Ali ndi kutseka bwino, kusefa bwino kwambiri, kukana kuyenda bwino, ndipo angagwiritsidwe ntchito kwa nthawi yayitali kuti achepetse mtengo wa zinthu zomwe zimagwiritsidwa ntchito mtsogolo, kupereka mpweya woyera ku malo ochitira mankhwala oyera. Ma fyuluta a hepa nthawi zambiri amayesedwa kutayikira asanachoke ku fakitale, koma anthu omwe si akatswiri amafunika kusamala kwambiri akamasamalira ndi kukhazikitsa. Kuyika kosayenera nthawi zina kumapangitsa kuti zinthu zodetsa zituluke kuchokera ku chimango kupita ku chipinda choyera, kotero mayeso ozindikira kutayikira nthawi zambiri amachitika pambuyo poyika kuti atsimikizire ngati fyulutayo yawonongeka; ngati bokosilo likutayikira; ngati fyulutayo yayikidwa bwino. Kuwunikanso nthawi zonse kuyenera kuchitika pambuyo pake kuti zitsimikizire kuti kusefa kwa fyulutayo kukugwirizana ndi zofunikira pakupanga. Njira zomwe zimagwiritsidwa ntchito kwambiri zimaphatikizapo zosefera zazing'ono za hepa, zosefera za deep pleat hepa, zosefera za gel seal hepa, ndi zina zotero, zomwe zimakwaniritsa cholinga cha ukhondo kudzera mu kusefa mpweya ndi kuyenda kuti zisefe tinthu ta fumbi mumlengalenga. Katundu wa fyuluta (wosanjikiza) ndi kusiyana kwa kuthamanga kwa fyuluta pamwamba ndi pansi ndizofunikanso. Ngati kusiyana kwa kuthamanga kwa fyuluta pamwamba ndi pansi pa fyuluta kukuwonjezeka, kufunikira kwa mphamvu ya mpweya woperekedwa ndi mpweya wotulutsa mpweya kudzawonjezeka, kuti pakhale kusintha kofunikira kwa mpweya. Kusiyana kwa kuthamanga pakati pa fyuluta pamwamba ndi pansi pa fyuluta zotere kungapangitse kuti mpweya ugwire bwino ntchito.
2. Muyezo wosinthira
Kaya ndi fyuluta ya hepa yomwe yayikidwa kumapeto kwa chipangizo choyeretsera mpweya kapena fyuluta ya hepa yomwe yayikidwa pa bokosi la hepa, izi ziyenera kukhala ndi zolemba zolondola za nthawi yogwirira ntchito komanso ukhondo ndi kuchuluka kwa mpweya ngati maziko osinthira. Mwachitsanzo, pogwiritsa ntchito mwachizolowezi, moyo wa fyuluta ya hepa ukhoza kukhala woposa chaka chimodzi. Ngati chitetezo chakutsogolo chili chabwino, moyo wa fyuluta ya hepa ukhoza kukhala woposa zaka ziwiri popanda vuto lililonse. Zachidziwikire, izi zimadaliranso mtundu wa fyuluta ya hepa, kapena kupitirira apo. Fyuluta ya hepa yomwe yayikidwa mu zida zoyeretsera, monga fyuluta ya hepa mu shawa ya mpweya, imatha kukhala ndi moyo wautumiki wa zaka zoposa ziwiri ngati fyuluta yoyamba yakutsogolo ili yotetezedwa bwino; monga fyuluta ya hepa pa benchi yoyera, titha kusintha fyuluta ya hepa kudzera mu pressure differential gauge pa benchi yoyeretsera. Fyuluta ya hepa pa shed yoyera imatha kudziwa nthawi yabwino yosinthira fyuluta ya mpweya kudzera mu liwiro la mpweya wa fyuluta ya mpweya ya hepa. Ngati ndi fyuluta ya mpweya ya hepa pa FFU fan filter unit, fyuluta ya hepa imasinthidwa kudzera mu prompt mu PLC control system kapena prompt ya pressure differential gauge. Zomwe zimayikidwa m'malo mwa ma hepa filters m'mafakitale opanga mankhwala zomwe zafotokozedwa mu clean workshop design specifications ndi izi: liwiro la mpweya limachepetsedwa kufika pamlingo wocheperako, nthawi zambiri osakwana 0.35m/s; resistance imafika kawiri kuposa mtengo woyamba wa resistance, ndipo nthawi zambiri imayikidwa pa 1.5 ndi mabizinesi; ngati pali kutayikira kosakonzedwa, malo okonzera sayenera kupitirira ma point atatu, ndipo malo onse okonzera sayenera kupitirira 3%, ndipo malo okonzera malo amodzi sayenera kupitirira 2cm*2cm. Ena mwa akatswiri athu odziwa bwino ntchito yoyika ma air filter afotokoza mwachidule zomwe akumana nazo, ndipo apa tikuwonetsa ma hepa filters m'mafakitale opanga mankhwala, tikuyembekeza kukuthandizani kumvetsetsa nthawi yabwino yosinthira fyuluta ya mpweya molondola. Pamene pressure differential gauge ikuwonetsa kuti air filter resistance imafika kawiri kapena katatu kuposa resistance yoyamba mu air conditioner unit, air filter iyenera kusungidwa kapena kusinthidwa. Ngati palibe njira yoyezera kuthamanga kwa mpweya, mungagwiritse ntchito njira yosavuta iwiri iyi kuti musankhe ngati ikufunika kusinthidwa: yang'anani mtundu wa fyuluta yomwe ili m'mbali za mphepo zakumtunda ndi pansi pa fyuluta ya mpweya. Ngati mtundu wa fyuluta yomwe ili m'mbali mwa mpweya wayamba kukhala wakuda, muyenera kukonzekera kuisintha; gwiritsani fyuluta yomwe ili m'mbali mwa mpweya wa fyuluta ya mpweya ndi dzanja lanu. Ngati muli ndi fumbi lambiri m'dzanja lanu, muyenera kukonzekera kuisintha; lembani momwe fyuluta ya mpweya imasinthira kangapo ndikufupikitsa nthawi yabwino kwambiri yosinthira; ngati kusiyana kwa kuthamanga kwa mpweya pakati pa chipinda choyera ndi chipinda chapafupi kumatsika kwambiri fyuluta ya mpweya ya hepa isanafike pa kukana komaliza, mwina kukana kwa fyuluta yoyamba ndi yachiwiri ndi kwakukulu kwambiri, ndipo muyenera kukonzekera kuisintha; ngati ukhondo m'chipinda choyera sukwaniritsa zofunikira pa kapangidwe kake, kapena kupanikizika koipa kumachitika, ndipo fyuluta yoyambirira ndi yachiwiri yogwira ntchito bwino sinafike nthawi yosinthira, mwina kukana kwa fyuluta ya hepa ndi kwakukulu kwambiri, ndipo muyenera kukonzekera kuisintha.
3. Nthawi yotumikira
Pogwiritsa ntchito bwino, fyuluta ya hepa mufakitale ya mankhwala imasinthidwa kamodzi pa chaka chimodzi kapena ziwiri (kutengera mtundu wa mpweya m'madera osiyanasiyana), ndipo deta iyi ndi yosiyana kwambiri. Deta yodziwira zomwe zachitika ingapezeke kokha mu projekiti inayake pambuyo potsimikizira ntchito ya chipinda choyera, ndipo deta yodziwira zomwe zachitika zoyenera chipinda choyera ingaperekedwe kokha pa shawa yoyera ya mpweya m'chipinda. Zinthu zomwe zimakhudza moyo wa ntchito ya mafyuluta a hepa: (1). Zinthu zakunja: Malo akunja. Ngati pali msewu waukulu kapena msewu kunja kwa chipinda choyera, pali fumbi lambiri, lomwe lidzakhudza mwachindunji kugwiritsa ntchito mafyuluta a hepa ndipo moyo wawo wogwirira ntchito udzachepa kwambiri. (Chifukwa chake, kusankha malo ndikofunikira kwambiri) (2). Malekezero akutsogolo ndi apakati a duct yopumira mpweya nthawi zambiri amakhala ndi mafyuluta oyamba ndi apakati kutsogolo ndi pakati pa duct yopumira mpweya. Cholinga chake ndikuteteza bwino ndikugwiritsa ntchito mafyuluta a hepa, kuchepetsa kuchuluka kwa zosintha, ndikuchepetsa ndalama zogulira. Ngati kusefa kwa kutsogolo sikuyendetsedwa bwino, moyo wa ntchito ya filter ya hepa udzafupikitsidwanso. Ngati zosefera zoyambira ndi zapakatikati zachotsedwa mwachindunji, nthawi yogwiritsira ntchito fyuluta ya hepa idzafupikitsidwa kwambiri. Zinthu zamkati: Monga tonse tikudziwa, malo osefera bwino a fyuluta ya hepa, ndiko kuti, mphamvu yake yosungira fumbi, imakhudza mwachindunji kugwiritsa ntchito fyuluta ya hepa. Kugwiritsa ntchito kwake kumagwirizana kwambiri ndi malo osefera bwino. Malo ogwirira ntchito akakula, kukana kwake kumakhala kochepa komanso nthawi yayitali yogwiritsira ntchito. Ndikofunikira kuyang'anitsitsa kwambiri malo osefera bwino komanso kukana kwake posankha zosefera za hepa. Kupatuka kwa fyuluta ya Hepa n'kosapeweka. Kaya ikufunika kusinthidwa iyenera kuyesedwa pamalopo. Muyezo wosinthira ukafika, uyenera kuyang'aniridwa ndikusinthidwa. Chifukwa chake, kufunika kwa moyo wa fyuluta sikungakulitsidwe mwachisawawa pakugwiritsa ntchito. Ngati kapangidwe ka dongosolo sikoyenera, chithandizo cha mpweya wabwino sichinakhazikitsidwe, ndipo dongosolo lowongolera fumbi la shawa yoyera m'chipinda silili la sayansi, nthawi yogwiritsira ntchito fyuluta ya hepa ya fakitale ya mankhwala idzakhala yochepa, ndipo ina iyenera kusinthidwa pasanathe chaka chimodzi. Mayeso ofanana: (1). Kuyang'anira kusiyana kwa kuthamanga kwa mpweya: Pamene kusiyana kwa kuthamanga kwa mpweya fyuluta isanafike komanso itatha kufika pamtengo wokhazikika, nthawi zambiri kumasonyeza kuti iyenera kusinthidwa; (2). Nthawi yogwiritsira ntchito: Onani nthawi yogwiritsira ntchito fyuluta, komanso weruzani mogwirizana ndi momwe zinthu zilili; (3). Kusintha kwa ukhondo: Ngati ukhondo wa mpweya mu workshop watsika kwambiri, mwina ntchito ya fyuluta yatsika ndipo kusintha kuyenera kuganiziridwa; (4). Dziwani chiweruzo: Pangani chiweruzo chokwanira kutengera zomwe mudagwiritsa ntchito kale komanso momwe fyulutayo imakhalira; (5). Yang'anani kuwonongeka kwa sing'anga, mawanga kapena madontho osinthika, mipata ya gasket ndi kusintha kwa mtundu kapena dzimbiri la chimango ndi chinsalu; (6). Yesani kukhulupirika kwa fyuluta, yesani kutayikira ndi kauntala wa fumbi, ndikulemba zotsatira zake ngati pakufunika.
