Ukukhetha okulungileyo I-ATEX fan ye-centrifugal akukhona malunga nokukhangela ibhokisi-imalunga nokuthintela ukuvutha kwizityalo zekhemikhali ezinothuli, ukuphepha ukusilela kwintlekele kwiindawo zepeyinti zokuphatha i-solvent-handling, okanye ukuqinisekisa ukuhamba komoya okuqhubekayo apho ugxininiso lwemethane luhamba kufuphi nemida yokuqhuma. Siye sabona amaziko achaza abalandeli "abalinganisiweyo be-ATEX" kuphela ukufumanisa-ngexesha lokugunyazisa-ukuba indawo evaliweyo yemoto ayizange iqinisekiswe kumaqela egesi ye-Zone 1, okanye ukuba izinto ezikhuphayo azikwazi ukumelana nokukhupha i-silica-laden exhaust. Yiyo loo nto ukhetho aluqali ngamanani ekhathalogu, kodwa ngemibuzo emithathu engaxoxisiyo: Luluphi ulwahlulo lwendawo eyingozi kanye? Bubuphi obona bushushu bokusebenza bomsinga womoya? Yaye luluphi uxinezeleko oluya kunyamezela ifeni—ukonakala, ukukrazuka, ukukhwela ibhayisekile eshushu, okanye zontathu ezi zinto?
Kutheni iSatifikethi se-ATEX Sifuna Ngakumbi Kuneleyibhile
An I-ATEX fan ye-centrifugal kufuneka ihlangabezane neemfuno ezimbini ezihambelanayo: inqanaba lokukhusela izixhobo (EPL) elihambelana nendawo (umzekelo, iGa ye-Zone 0, i-Gb ye-Zone 1), kunye nokuhambelana kweqela legesi (IIC ye-hydrogen / acetylene, i-IIB ye-ethylene, i-IIA ye-propane). Kodwa isiqinisekiso sodwa asiqinisekisi ukusebenza kwentsimi. Kwiprojekthi enye yokucokisa, i-fan iphumelele uvavanyo lwe-ATEX kwi-25 ° C ambient-kodwa ayiphumelelanga ngexesha lokuqalisa kwehlobo xa ubushushu bomphezulu we-casing budlula i-T4 (135 ° C) ngenxa yoyilo olungonelanga lokutshatyalaliswa kobushushu. Ukuthotyelwa kwelizwe lokwenyani kuthetha ukungqinisisa udidi olushushu *phantsi kweemeko zokwenyani zomsebenzi*, hayi iimeko zaselebhu kuphela. Kukwathetha ukuqinisekiswa kwecandelo ngalinye-eliphethe izitywina, imikhono yeshaft, kunye neziqhoboshi - zidweliswe kumda wesatifikethi. Sihlala sijonga iziqinisekiso zeemviwo zohlobo lwe-EC ngokuchasene neeyunithi zomzimba ngaphambi kokuba zithunyelwe. Akukho ngqikelelo. Akukho ngaphandle.
Ukhetho Loyilo Olunqanda Ukungaphumeleli-Akuhlangatyezwanga nje Nemigangatho
Ifeni eqinisekisiweyo iyasilela ukuba ulwakhiwo lwayo luyachasana nokusingqongileyo. Qwalasela ezi zigqibo ezingqiniweyo:
- I-Impeller imathiriyeli ibaluleke ngaphezu koxinzelelo lwe-static. I-aluminiyam i-impellers i-spark kwindawo ye-carbon black dust-nangemvume ye-ATEX. I-Titanium okanye i-steel-stainless-steel iyayisusa loo ngozi, kodwa ifuna ulungelelwaniso oluchanekileyo ukunqanda ukuguga okubangelwa yi-vibration kwintsebenzo eqhubekayo ye-24/7.
- Ukudityaniswa kweemoto akuyoplagi kunye nokudlala. Imoto eqinisekisiweyo ye-ATEX efakwe kwizindlu zefeni ezingaqinisekisiweyo ivala yonke indibano. Iyunithi epheleleyo-kubandakanya ukudibanisa idrayivu, ukugada, kunye nefreyimu yesiseko-kufuneka ivavanywe njengenkqubo enye.
- Isicwangciso sokutywinwa sichaza ixesha elide. Izitywini zomlomo eziqhelekileyo zivuza uthuli kwiibheringi phakathi kweenyanga kumbhobho wezityalo zesamente. Iinkqubo zokuhlanjululwa koxinzelelo oluhle kunye nenaliti yegesi engasebenziyo yandisa ubomi benkonzo nge-3-5 × kwiindawo ezinobumba obuphezulu.
Sithathe indawo yabalandeli belifa abali-120 kwizikhululo zamandla ezibaswa ngamalahle apho irhasi ye-desulfurization flue yabangela ukuthotywa okukhawulezileyo kweekhabhoni eziqhelekileyo zentsimbi. Ukutshintshela kwii-double-inlet centrifugal fans kunye ne-epoxy-coated casings kunye ne-Hastelloy-C276 impellers zinqumle ixesha lokuphumla elingacwangciswanga nge-78%-ngaphandle kokulahla ingqibelelo ye-ATEX.
Ukwenza ngokwezifiso ayisiyonto iLuxury-yeyona ndlela yokudibanisa inyani
Ngaphandle kweshelufu abalandeli be-ATEX baphatha iimeko zeencwadi zokufunda. Iisayithi zokwenyani azilandeli iincwadi zezifundo. Igumbi lokucoca amayeza lifuna umoya ongaqhubi kudubula kunye ≤25 dB(A) ingxolo-ayinakwenzeka ngezithinteli eziqhelekileyo ze-radial-tip. Isisombululo: isishukumiso se-titanium egobileyo ngasemva, umgca we-acoustic odityaniswe kwi-volute, kunye ne-IE4 eqhuba ngokuthe ngqo i-motor esusa umngcipheko we-belt-drive sparking. Ixesha elipheleleyo lokuhambisa: iiveki ze-11. Omnye umxhasi kumgca wokuvelisa i-sulfuric acid efuna ukuchasana ne-H₂SO₄ inkungu kwi-80 ° C ngelixa ugcina isatifikethi se-Zone 1 IIB. Iingubo ezisemgangathweni ze-epoxy zithotyiwe. Sisebenzise i-fluoropolymer-lined cast cast iron casings kunye ne-ceramic-coated shaft extensions-kunye ne-coefficients yokwandiswa kwe-thermal eqinisekisiweyo kuluhlu olupheleleyo lokusebenza.
Isiko akuthethi ukucotha. I-machining yethu yangaphakathi, i-sheet metal fabrication, kunye nemigca yokulinganisa eguquguqukayo masiguqule i-geometry ye-casing, ukulungelelanisa i-inlet / outlet flanges, ukudibanisa i-sensors yeqondo lokushisa, okanye ukongeza amachweba okucoca-konke ngaphandle kokulibaziseka kokuqinisekiswa kwakhona, kuba sisebenza ngaphakathi kwemida yoyilo evunyiweyo kwangaphambili.
Yintoni Eza Emva Kokuba I-invoyisi Imisele Ukhuseleko—Ayikokuthobela Nje Kuphela
Amaxwebhu yindlela yakho yokuqala yokuzikhusela ngexesha lophicotho-zincwadi okanye lophando lwezehlo. Yonke I-ATEX fan ye-centrifugal ukusuka eZibo Hongcheng Fan Co., Ltd. iinqanawa ezinefayile epheleleyo yobugcisa: isatifikethi soviwo lwe-EC-uhlobo, iingxelo zovavanyo (ukungcangcazela, ingxolo, ukunyuka kweqondo lokushisa), iziqinisekiso zezinto eziphathekayo, kunye nofakelo oluthile lwe-torque specs-hayi iincwadana eziqhelekileyo. Sibandakanya iipleyiti ezinekhowudi ze-QR ezinxibelelanisa kwimizobo ephila ngokutsha elawulwa ngokutsha kunye noluhlu lweendawo ezisecaleni. Xa indawo yepetrochemical e-Oman idinga ukutshintshwa ngokungxamisekileyo kwebhoyila eyoyisakalayo yokuvuthela i-centrifugal, iqela lethu lobunjineli liye laphonononga iibholiti zesiseko ezikhoyo, ukunyamezelwa kolungelelwaniso lwemibhobho, kunye ne-harmonics yamandla ombane wegridi yasekhaya-emva koko kuthunyelwe indawo yokulahla kunye neeparamitha ze-VFD esetwe kwangaphambili kunye nokuqinisekiswa kokujikeleza kwesigaba. Akukho ngqikelelo. Akukho msebenzi wobunjineli kwakhona.
Ukhuseleko alufikelelwa ekugunyazisweni. Igcinwe ngolondolozo oluqikelelwayo, iindawo ezinokulandeleka, kunye neenjineli ezime kwigumbi lakho lokulawula ngexesha lokuqalisa. Yiyo loo nto inkxaso yethu ibandakanya uqeqesho oluthe ngqo kwisicelo-kungekhona nje "indlela yokuyivula," kodwa "indlela yokubona ukuthotywa kwenqanaba lokuqala kwindawo yokufuma ephezulu yeZone 2."
