Ukunemba Kobunjiniyela Kokugcina Okusebenza Kahle Kwezithako Zokuxuba Amakhava Esilo
Isivalo sesilo sokugcina izithako kufanele senze izinto ezintathu ngesikhathi esisodwa: sivimbe uthuli, sivimbe umswakama, futhi sinikeze ithimba lokuhlanza indlela yokungena engangcolisi iqoqo. Ezithakweni zemithi, lokho kusho umphetho ovaliwe oboshiwe one-EPDM gasket namabhawodi e-8.8-grade, uhlobo lwephahla olukhethwe ngokumelene nomoya wendawo kanye nomthwalo weqhwa futhi kubhekiselwe ku-AWWA D108 noma API 650 ne-ADM 2015 ne-ASCE 7-10, kanye nengaphakathi elingahlanzeka ngempela, kungaba udonga lwengilazi oluhlanganiswe nensimbi olune-Ra engaphansi kuka-0.8 µm noma igobolondo le-316L stainless. Isivalo futhi siwumngcele womhwamuko, ngakho-ke indlela ye-condensate kufanele yakhiwe futhi ingashiywa ku-insulation.
Ukusingathwa kwempushana ye-Pharma kunesicelo esiqinile kunomsebenzi omningi wezinto eziqinile eziningi. I-excipient ingase ingasebenzi, kodwa i-Spec yekhasimende ibhalwe ngokumelene nokuqukethwe komswakama, usayizi wezinhlayiyana kanye nenani lamagciwane, futhi impelasonto eyodwa emanzi ngaphakathi kwe-silo ingenza inqwaba iphume ngaphandle kwencazelo. Ngasikhathi sinye i-silo ihlezi ngaphakathi kwemboni lapho uthuli luyimkhiqizo, hhayi inhlupheko, ngakho uphahla kufanele luhlale luvaliwe ngaphansi kokudonswa kokuqoqwa kothuli kwemboni ngenkathi i-silo ithululwa. Amaqembu obunjiniyela bokunemba okuphezulu kwe-excipients yokugcina ama-silo covers alinganisa lezo zidingo ezimbili ngokumelene nesithathu esingavamile ukudwetshwa: ithimba lokulungisa kufanele likwazi ukuvula uphahla, lihlanze umugqa, futhi liphinde livalwe ngaphandle kokwethula izinhlayiyana.
Izimo ezintathu zomthwalo wesivalo sesilo sezithako
Uthuli, umswakama kanye nokufinyeleleka. Okokuqala kusobala: umngcele wothuli onqenqemeni, isivalo sophahla kanye nakho konke ukungena, kubanjwe ngaphansi kwengcindezi engemihle umqoqi wothuli awusebenzisayo ngesikhathi sokukhipha. Okwesibili yikho okubangela izinkinga ze-excipient. Isilo esigcwele i-powder efudumele bese siphola sizokwakheka ngaphakathi kumphezulu wophahla; uma lawo manzi ehla aye emkhiqizweni, i-lot isengozini. Okwesithathu ukufinyeleleka: isivalo sophahla, umsele we-gasket ohlanzekayo, kanye nomqenqema ongagcini i-powder, ngoba umqenqema ogcwele i-powder ecindezelwe awukwazi ukuvala.
Impendulo yokuklama emswakameni womswakama iwukuthi indawo yekhanda iphathwe njengevolumu elawulwayo. Yiyise emoyeni ohlanzekile owenziwe womile noma ohlelweni lomoya ohlanzekile wemboni, tshekisa uphahla lwangaphakathi ukuze noma yimaphi amanzi ajijile afinyelele emseleni wamanzi noma kumbhobho wokugeza, futhi gcina umsele we-gasket ngaphandle komugqa wokuvikela kunokuba ube sendleleni yothuli.
Ukukhetha uhlobo lophahla
Isimo somthwalo sinquma i-geometry. I-aluminium geodesic dome iyisinqumo esivamile se-silo enkulu eboshwe ngamabhawodi enobubanzi obukhulu: isabalalisa kahle umoya ophakamayo neqhwa, yengeza isisindo esincane esifile, futhi inikeza umugqa ocwebileyo wokugoqa kanye nombuthano wamabhawodi. Yakhelwe nge-AWWA D108 noma i-API 650, nesimo somoya neqhwa sithathwe ku-ADM 2015 kanye ne-ASCE 7-10 yesizinda. Uphahla lwamapuleti eboshwe ngohlaka lufaneleka isilo encane, lunikeza indawo yokusebenzela, futhi kulula ukulufaka ngezindlela zokuhamba nezinsimbi zokubamba; i-cone engashoni ithambile kodwa idinga umthambeka oqondile ukuze ikhiphe iqhwa futhi idla indawo yekhanda.
Noma yiluphi uhlobo, imininingwane yomphetho yenza umsebenzi. I-flange yophahla iboshelwa kuringi ephezulu yegobolondo nge-gasket ye-EPDM namabhawodi ezinga le-8.8 kuzungeze umjikelezo wonke, futhi isembozo sangaphakathi somphetho kufanele siqhubeke ukuze impushana ingangeni emgodini. Isicabha, indawo yokukhipha uthuli, ukuxhumana komoya kanye nanoma iyiphi indawo yethuluzi lezinga konke kuhlezi kulo mdwebo ofanayo wokuxhumana.
Impahla yangaphakathi yesilo se-excipients
Ikhono lokuhlanjululwa liwukucaciswa, hhayi ukuqedwa. Amasistimu amabili angaphakathi amboza iningi lama-excipients. Udonga lwengilazi oluhlanganiswe nensimbi lushiswa ku-820 kuya ku-930 °C ngesendlalelo se-enamel esingu-0.25 kuya ku-0.45 mm, kulinganiswa ngaphezu kuka-3,450 N/cm², ngobukhulu bendawo engaphansi kwe-Ra 0.8 µm; alunazimbobo, kulula ukuligeza, futhi luyabekezelela ububanzi be-pH kusuka ku-1 kuya ku-14, okusiza uma i-silo efanayo ingase ithathe umfudlana oxubile noma owenziwe ngama-pellets. Igobolondo lensimbi engagqwali engu-316L iyisinqumo lapho umkhiqizo udinga indawo emanzi yensimbi ephelele, ngezindleko eziphindwe kaningi kune-GFS, nangalapho ikhasimende licela ukuqedwa okucwebezelisiwe kanye ne-passivation ebhaliwe.
Kumaqembu okumboza ngokwawo, gcina izindawo zangaphakathi zibushelelezi futhi ziqhubekayo, gwema izindonga lapho impushana ingahlala khona, futhi ucacise isivalo kanye ne-gasket yaso njengezinto ezingahlanzwa zisendaweni. Lapho kusetshenziswa isilo se-GFS, imiphetho yamaphaneli ilungiswa efektri futhi amaphaneli ahlolwa nge-spark nge-1500 V DC ngaphambi kokuthunyelwa, ngakho-ke ingaphakathi lifika lingenazo izimbobo ezincane ezingaba yinkinga yokuhlanza.

Precision excipients storage silo covers are won in the rim detail and lost in the vapour path. Seal the boundary with a gasketed bolted flange, choose the roof form against the real wind and snow case, size the vent from the filling air displacement, and pick an interior that can be washed rather than one that merely looks smooth. For a pharmaceutical bulk powder silo, the practical decision is between a fused enamel interior with 1500 V spark tested panels and a 316L stainless shell, and both are deliverable from the same bolted silo platform. Send the powder data, the batch size, the diameter and the site load case to the engineering desk and the roof form, rim detail and document package will follow.
