CHITSOGOZO CHATHUNTHU CHOYERETSA BECHI

Kuwona kwa Mpweya
Kapangidwe ka mabenchi oyera sikunasinthe kwambiri m'zaka 40 zapitazi. Pali zosankha zambiri ndipo chifukwa chake komanso zomveka bwino za hood yomwe ili yoyenera kugwiritsidwa ntchito kwanu zimasiyana malinga ndi momwe ntchito yanu ilili, zida zomwe zimagwiritsidwa ntchito, komanso kukula kwa malo omwe mukuyikamo.

Kuyenda kwa Laminar ndi mawu omwe amagwiritsidwa ntchito pofotokoza mayendedwe a mpweya omwe ali ndi liwiro lofanana, zomwe zimapangitsa kuti kuyenda kwa mpweya/liwiro kuyende mbali imodzi popanda mafunde a eddy kapena reflux m'dera logwirira ntchito. Pa mayunitsi oyenda pansi, kuyesa kwa utsi wowonera kayendedwe ka mpweya kungagwiritsidwe ntchito kuwonetsa madigiri ochepera 14 kuchokera pamwamba mpaka pansi (dera logwirira ntchito).

Muyezo wa IS0-14644.1 umafuna kuti pakhale gulu la ISO 5 - kapena Gulu 100 mu Federal Standard 209E yakale yomwe anthu ambiri amaitchulabe. Dziwani kuti kuyenda kwa laminar tsopano kwasinthidwa ndi mawu oti "kuyenda kwa unidirectional" pa zikalata za ISO-14644 zomwe zikulembedwa pano. Kuyika kwa benchi yoyera mu chipinda choyera kuyenera kufufuzidwa ndikusankhidwa mosamala kwambiri. Zosefera za HEPA za padenga, ma grill operekera, ndi kayendedwe ka anthu ndi zinthu zonse ziyenera kukhala gawo la equation ya mtundu wa hood, kukula ndi malo.

Mitundu ya ma hood imasiyana malinga ndi komwe madzi akuyenda, console, bench top, table top, yokhala ndi ma casters, yopanda ma casters, ndi zina zotero. Ndikambirana zina mwa zosankha komanso zabwino ndi zoyipa za chilichonse, ndi cholinga chothandiza makasitomala kupanga zisankho zophunzitsidwa bwino pa zomwe zingakhale zabwino pa nkhani iliyonse. Palibe chimodzi chomwe chimagwirizana ndi zonse mu mapulogalamu awa, chifukwa onse amasiyana.

Benchi Yoyera ya Model ya Console
Chotsani mpweya pansi pa malo ogwirira ntchito bwino pochotsa tinthu tomwe timapangidwa pansi modutsa m'chipinda chotsukira;
·Moto uli pansi pa malo ogwirira ntchito zomwe zimapangitsa kuti zikhale zosavuta kupeza;
· Zingakhale zoyima kapena zopingasa nthawi zina;
·N'zovuta kuyeretsa pansi pa pansi;
·Kuyika ma casters pansi kumakweza chivundikirocho, komabe kuyeretsa ma casters n'kosatheka;
·Njira yoyeretsera ndi yofunika kwambiri chifukwa thumba la IV lili pakati pa fyuluta ya HEPA ndi malo ogwirira ntchito ndipo mpweya woyamba umakhala wofooka.

Benchi Loyera Pamwamba pa Tebulo
· Zosavuta kuyeretsa;
·Tsegulani pansi kuti magalimoto, zinyalala kapena malo ena osungira zinthu agwiritsidwe ntchito;
· Bwerani mu mayunitsi oyenda molunjika komanso molunjika;
·Imabwera ndi mafani/ma intakes otsika pa mayunitsi ena;
· Bwerani ndi ma casters, omwe ndi ovuta kuyeretsa;
·Ma fan omwe ali pamwamba amachititsa kuti chipinda chisasefedwe, amakoka mpweya kupita ku denga lomwe limanyamula ndi kuyika tinthu tomwe timapangidwa ndi kuyenda kwa munthu m'chipinda chotsukira.

Malo Oyera: ISO 5
Zosankha izi, kwenikweni, ndi mipando yoyera yomangidwa m'makoma/madenga a chipinda chotsukira kukhala gawo la kapangidwe ka chipinda chotsukira. Izi nthawi zambiri zimachitika popanda kuganizira kwambiri komanso kuganizira pasadakhale nthawi zambiri. Sizinayesedwe ndi kutsimikiziridwa kuti zitha kubwerezedwanso poyesa ndi kuyang'anira, chifukwa cha momwe zinthu zonse zopangidwa zimakhalira, motero FDA imawachitira mosakayikira. Ndikugwirizana nawo pa malingaliro awo chifukwa omwe ndawona ndi kuyesa sagwira ntchito monga momwe wopanga amaganizira. Ndikupangira kuyesa izi pokhapokha ngati pali zinthu zina, kuphatikizapo:
1. Chowunikira mpweya kuti chitsimikizire kuthamanga;
2. Madoko oyesera kutayikira kwa madzi ali pamalopo;
3. Palibe magetsi omwe ali mkati mwa hood;
4. Palibe chimango chomwe chimagwiritsidwa ntchito pa chishango/nsalu yolowera mbali;
5. Tinthu tating'onoting'ono timasunthika ndipo timagwiritsidwa ntchito pafupi ndi malo ovuta kwambiri;
6. Njira yoyesera yolimba imapangidwa ndi kuchitidwa mobwerezabwereza pogwiritsa ntchito kanema;
7. Khalani ndi chotchingira chobowola chochotseka pansi pa chipangizo cha mphamvu ya fan HEPA kuti chiziyenda bwino mbali imodzi;
8. Gwiritsani ntchito malo ogwirira ntchito achitsulo chosapanga dzimbiri omwe amachotsedwa pakhoma lakumbuyo kuti alole kuti kumbuyo/mbali mwa tebulo ndi khoma ziyende bwino. Ayenera kusunthika.

Monga mukuonera, zimafuna kuganizira kwambiri kuposa momwe chivundikiro chopangidwa kale chimachitira. Onetsetsani kuti gulu lopanga mapulani lamanga malo okhala ndi malo oyera a ISO 5 m'mbuyomu omwe adakwaniritsa malangizo a FDA. Chinthu chotsatira chomwe tiyenera kuganizira ndi komwe tingapeze mipando yoyera m'chipinda choyera? Yankho lake ndi losavuta: musawaike pansi pa fyuluta ya HEPA ya denga ndipo musawaike pafupi ndi zitseko.

Poganizira za kuipitsidwa kwa zinthu, mipando yoyera iyenera kukhala kutali ndi njira zoyendera kapena njira zoyendera. Ndipo, izi siziyenera kuyikidwa pakhoma kapena kuphimba ma air grills. Malangizo ndi akuti mulole malo m'mbali, kumbuyo, pansi ndi pamwamba pa ma hood kuti athe kutsukidwa mosavuta. Chenjezo: Ngati simungathe kuyeretsa, musachiyike m'chipinda choyera. Chofunika kwambiri, chiyikeni m'njira yoti akatswiri athe kuyesa ndi kupeza.

Pali zokambirana zokhudza, kodi zingayikidwe moyang'anizana? Zolunjika pa wina ndi mnzake? Zobwerera m'mbuyo? Ndi chiyani chabwino? Zimadalira mtundu, mwachitsanzo wowongoka kapena wopingasa. Pakhala mayeso ambiri pa mitundu yonse iwiri ya ma hood, ndipo malingaliro amasiyana pa yomwe ikugwirizana bwino ndi ntchito zosiyanasiyana. Sindithetsa nkhaniyi ndi nkhaniyi, komabe ndipereka malingaliro anga pa njira zina zoganizira zomwe zilipo pa mapangidwe awiriwa.
