GCWALISA ISIKHOKELO SOKUCOCA IBHNSHI

Ukubonwa kokuhamba komoya
Uyilo lweebhentshi ezicocekileyo aluzange lutshintshe kakhulu kwiminyaka engama-40 edlulileyo.Iinketho zininzi kwaye isizathu kunye nengqiqo yokuba yeyiphi ihood elungele isicelo sakho iya kwahluka malunga nokuba zithini na iinkqubo zakho, izixhobo ezisetyenziswa kwinkqubo, kunye nobukhulu bendawo obeka kuyo.

I-Laminar flow is the verbiage esetyenziselwa ukuchaza iintshukumo zomoya ezithe nkqi kwisantya, zenza i-unidirectional flow/velocity ihamba kwicala elinye kungekho misinga eddy okanye i-reflux kwindawo yomsebenzi.Kwiiyunithi ezihamba phantsi, uvavanyo lwe-visual flow visualization ingaqeshwa ukubonisa ngaphantsi kwe-14 degrees offset ukusuka phezulu ukuya ezantsi (indawo yomsebenzi).

Umgangatho we-IS0-14644.1 ubiza ukuhlelwa kwe-ISO 5 - okanye i-Class 100 kwi-Federal Standard Standard 209E apho abaninzi abantu basabhekisela kuyo.Nceda uqaphele ukuba ukuhamba kwe-laminar ngoku kuthatyathelwe indawo ngamagama athi "unidirectional flow" kumaxwebhu e-ISO-14644 abhalwayo ngoku.Ukubekwa kwebhentshi ecocekileyo kwigumbi lokucoca kufuneka kuhlalutywe kwaye kukhethwe ngononophelo.Izihluzi ze-Ceiling HEPA, iigrill zokubonelela, kunye nokuhamba kwabantu kunye neemveliso zonke kufuneka zibe yinxalenye ye-equation yohlobo lwe-hood, ubungakanani kunye nokubeka.

Iindidi zeehoods ziyahluka malunga necala lokuhamba, i-console, i-bench top, i-table top, kunye ne-casters, ngaphandle kwee-casters, njl. abathengi abenza izigqibo ezifundileyo malunga nokuba yeyiphi eya kuba ngcono kwimeko nganye.Akukho ubungakanani obufanayo-konke kwezi zicelo, njengoko zonke ziyahluka.

Ibhentshi yeConsole ecocekileyo
Susa umoya ngaphantsi kwendawo yokusebenza ngokutshayela ngokufanelekileyo umgangatho wamasuntswana awenziwe ahamba kwigumbi lokucoca;
·Imoto ibekwe ngaphantsi kwendawo yokusebenza isenza kube lula ukufikelela kuyo;
·Inokuthi nkqo okanye ithe tye kwiimeko ezithile;
·Kunzima ukucoca ngaphantsi komzantsi;
·Ukubeka iicaster emazantsi kuphakamisa ihood, nangona kunjalo ukucoca iicaster phantse akunakwenzeka;
·Indlela yokubulala iintsholongwane ibaluleke kakhulu kuba i-IV bag iphakathi kwesihluzo se-HEPA nomphezulu wokusebenza kwaye umoya wokuqala usengozini.

I-Table Top Clean Bench
·Ukucoca kulula;
·Vula ngaphantsi ukuze kusetyenziswe iinqwelo, inkunkuma okanye enye indawo yokugcina;
·Ngena kwiyunithi yokuhamba ethe tye & ethe nkqo;
·Yiza namathontsi asezantsi/abalandeli kwezinye iiyunithi;
·Yiza neecasts, ekunzima ukuzicoca;
·Ukungena kweefeni ngaphezulu kubangela ukujikelezwa kokucoca kwegumbi, ukutsalela umoya ukuya kwindawo yokuphakamisa isilingi kunye nokuxhoma amasuntswana aveliswa yintshukumo yomntu kwigumbi lokucoca.

Iindawo ezicocekileyo: ISO 5
Ezi zikhetho, ngokufanelekileyo, iibhentshi ezicocekileyo ezakhiwe kwiindonga / iisilingi zegumbi lokucoca ziyinxalenye yoyilo lwegumbi lokucoca.Ezi zikholisa ukwenziwa ngokuqwalaselwa okuncinci kunye nokucingelwa kwangaphambili kwiimeko ezininzi.Abakhange bavavanywe kwaye bangqinwe ukuba bayaphinda-phinda kuvavanyo kunye nokubeka iliso, njengoko zonke iihood ezenziweyo zinjalo, ngenxa yoko i-FDA ibaphatha ngokuthandabuza okukhulu.Ndiyavumelana nabo kwizimvo zabo njengoko endizibonileyo ndaza ndavavanywa zingasebenzi njengoko umyili ebecinga ukuba ziya kwenjenjalo.Ndingacebisa ukuba uzame oku kuphela ukuba kukho izinto ezithile, kubandakanya:
1. Ukuhlola ukuhamba komoya ukubonisa isantya;
2. Amazibuko okuvavanya ukuvuza akhona;
3. Akukho zibane zikhoyo ngaphakathi kwehood;
4. Akukho freyim isetyenziswayo kwi-directional flow shield/sash;
5. Izixhobo zokubala zesuntswana ziyashukuma kwaye zisetyenziswa kufutshane nendawo yokubaluleka;
6. Inkqubo yovavanyo eyomeleleyo iyilwe kwaye yenziwe ngokuphindaphindiweyo ngokucofa ividiyo;
7. Yiba ne-screed enemingxuma ekhutshwayo ngezantsi kweyunithi ye-HEPA yamandla eFan ukuvelisa ukuhamba kakuhle kwe-unidirectional;
8. Sebenzisa umphezulu womsebenzi wentsimbi engenasici otsalwe eludongeni olungasemva ukuvumela ukuhamba ukugcina umva/amacala etafile kunye nodonga ecocekile.Kufuneka ishukumiseke.

Njengoko ubona, ifuna ingcinga eninzi ngakumbi kunehood eyenziwe ngaphambili.Qinisekisa ukuba iqela loyilo liye lakha indawo ene-ISO 5 kwindawo ecocekileyo kwixesha elidlulileyo eliye ladibana nezikhokelo ze-FDA.Into elandelayo ekufuneka sijongane nayo kukuba zifumaneka phi iibhentshi ezicocekileyo kwigumbi lokucoca?Impendulo ilula: musa ukuzibeka phantsi kwayo nayiphi na isihluzo se-HEPA kwaye ungazibeki kufutshane neminyango.

Ukusuka kwindawo yokulawula ukungcola, iibhentshi ezicocekileyo kufuneka zibekwe kude neendlela zokuhamba okanye iindlela zokuhamba.Kwaye, ezi akufuneki zibekwe eludongeni okanye zigqume iigrill zomoya zokubuya nazo.Ingcebiso kukuvumela igumbi emacaleni, ngasemva, ezantsi nangaphezulu kweehood ukuze zicocwe lula.Isilumkiso: Ukuba awukwazi ukuyicoca, musa ukuyibeka kwigumbi elicocekileyo.Okubalulekileyo, zibeke ngendlela yokuvumela uvavanyo kunye nofikelelo ngamagcisa.

Kukho iingxoxo malunga nokuba, ngaba zinokubekwa ngaphesheya komnye nomnye?Perpendicular omnye komnye?Umva nomva?Yiyiphi eyona ilungileyo?Kulungile, kuxhomekeke kuhlobo, okt nkqo okanye tye.Kubekho uvavanyo olubanzi kuzo zombini ezi ntlobo zee-hoods, kwaye izimvo ziyahluka malunga nokuba yeyiphi ekufanelekele usetyenziso olwahlukileyo.Andiyi kuyicombulula le ngxoxo kunye neli nqaku, nangona kunjalo ndiya kunika izimvo zam kwezinye iinkqubo zokucinga phaya kuyilo ezimbini.
