Kusarudza zvakanaka ATEX centrifugal fan haisi yekutarisa bhokisi - ndezvekudzivirira kupisa mumiti ine guruva, kudzivirira kutadza kunotyisa mumatehwe ependi ekugadzirisa zvinonyungudutsa, kana kuve nechokwadi chekuenderera kwemhepo uko methane yakawanda inotenderera pedyo nemiganhu inoputika. Isu takaona zvivakwa zvichitsanangura "ATEX-yakatemerwa" mafani kuti angoona-panguva yekumisikidzwa-kuti iyo mota yakavharirwa haina kunyoreswa kuZone 1 mapoka egasi, kana kuti iyo impeller haigone kumira neabrasive silica-yakaremerwa exhaust. Ndosaka kusarudzwa kunotanga kwete nenhamba dzekarodha, asi nemibvunzo mitatu isingagone kutaurirana: Ndeipi chaiyo ine njodzi nzvimbo yekuisa? Ndeipi yakanyanya kupisa tembiricha yemhepo? Uye ndezvipi zvinonetsa izvo feni ichatsungirira—kuora, kuboora, kuchovha bhasikoro, kana kuti zvose zvitatu?
Nei ATEX Certification ichida Zvakawanda Kupfuura Label
An ATEX centrifugal fan inofanira kusangana nezvinodiwa zviviri zvakafanana: chiyero chekudzivirira kwemidziyo (EPL) inoenderana nenzvimbo (semuenzaniso, Ga yeZone 0, Gb yeZone 1), uye kuenderana kweboka regasi (IIC yehydrogen/acetylene, IIB yeethylene, IIA yepropane). Asi certification chete haivimbisi kuita kwemunda. Mune imwe purojekiti yekunatsa, feni yakapfuura bvunzo dzeATEX pa25 ° C ambient-asi yakakundikana panguva yekutanga kwechirimo apo tembiricha yepasi yecasing yakapfuura T4 (135 ° C) nekuda kwekusakwana dhizaini yekubvisa kupisa. Kuteera kwepasirese kunoreva kuongorora kirasi yekupisa *pasi pemamiriro chaiwo ebasa*, kwete chete mamiriro emurabhoritari. Zvinorevawo kusimbisa chikamu chese- chinotakura zvisimbiso, shaft maoko, kunyangwe zvisungo - chakanyorwa muchikamu chetifiketi. Isu tinowanzo kuyambuka-kutarisa EC-mhando yebvunzo zvitupa zvinopesana nemuviri zvikamu zvisati zvatumirwa. Hapana fungidziro. Hapana kunze.
Sarudzo Dzekugadzira Dzinodzivirira Kukundikana—Kwete Kungosangana Nemitemo
Fani yakasimbiswa inokundikana kana kuvakwa kwayo kunopesana nenharaunda yayo. Funga nezvezvisarudzo izvi zvakasimbiswa mumunda:
- Impeller zvinhu zvakakosha kupfuura static pressure rating. Aluminium impellers inopenya munzvimbo dzeguruva dema-kunyangwe nemvumo yeATEX. Titanium kana simbi isina-simbi yakasiyana inobvisa njodzi iyoyo, asi inoda kudzikamisa zvine simba kuti udzivise kuzunguzika-kunokonzeresa kutakura kupfeka mukuenderera mberi kwe24/7 kushanda.
- Kubatanidzwa kwemota hakusi plug-uye-kutamba. Iyo ATEX-yakasimbiswa mota yakaiswa pane isina-certified fan fan inobvisa kuteedzera kwegungano rese. Iyo yakazara unit-inosanganisira drive coupling, gadhi, uye base frame-inofanirwa kuyedzwa seimwe system.
- Kuisa chisimbiso nzira inotsanangura hupenyu hurefu. Standard lip seals inodonhedza huruva mumabearings mukati memwedzi mukupopota simende. Positive-pressure purge masisitimu ane inert gasi jekiseni anowedzera hupenyu hwesevhisi ne3-5 × munzvimbo dzakakwirira-dzinoumbwa.
Takatsiva anopfuura zana nemakumi maviri enhaka mafeni muzviteshi zvemagetsi emarasha uko desulfurization flue gasi yakakonzera kuparara nekukurumidza kweyakajairwa kabhoni simbi casings. Kuchinjira kune mbiri-inlet centrifugal mafeni ane epoxy-yakavharwa casings uye Hastelloy-C276 impellers inocheka isina kurongeka yekudzikira ne78%-pasina kukanganisa kuvimbika kweATEX.
Kugadzirisa Haisi Yehumbozha-Ndiyo Chete Nzira yekufananidza Chokwadi
Kunze-pasherufu mafeni eATEX anobata zvinyorwa zvebhuku. Saiti chaidzo hadziteveri mabhuku. Imba yekuchenesa mishonga yaida kuputika-inopinza mhepo ine ≤25 dB(A) ruzha-hazvigoneke neyakajairwa radial-tip impeller. Solution: tsika yekudzokera kumashure-yakakomberedzwa titanium impeller, acoustic lining yakabatanidzwa mune volute, uye yakananga-kutyaira IE4 mota inobvisa bhandi-drive sparking njodzi. Yese yekuendesa nguva: 11 mavhiki. Mumwe mutengi mumutsara wekugadzira sulfuric acid aida kuramba mhute H₂SO₄ pa80°C uchichengetedza Zone 1 IIB certification. Standard epoxy coatings delaminated. Takashandisa fluoropolymer-lined cast cast iron casings ane ceramic-coated shaft edzedzero-uye akasimbisa ekuwedzera kwemafuta ekuwedzera mukati meiyo yakazara inoshanda renji.
Tsika hazvirevi kunonoka. Yedu-mu-house machining, sheet metal fabrication, uye dynamic balancing mitsara ngatigadzirise casing geometry, adapta inlet/outlet flanges, batanidza tembiricha sensors, kana kuwedzera purge ports-zvose pasina kudzoreredza kunonoka kupihwa, nekuti isu tinoshanda mukati meyakatemerwa dhizaini miganhu.
Chii Chinouya Mushure mekunge Invoice Yaona Kuchengeteka—Kwete Kungoteerera
Zvinyorwa ndiwo mutsara wako wekutanga wekudzivirira panguva yekuongorora kana kuongorora chiitiko. Every ATEX centrifugal fan kubva kuZibo Hongcheng Fan Co., Ltd. ngarava ine yakazara tekinoroji faira: EC-mhando yebvunzo chitupa, mishumo yebvunzo (kuzunguzika, ruzha, kukwira kwetembiricha), zvitupa zvezvinhu, uye kuisirwa-chaiyo torque specs-kwete generic manual. Isu tinosanganisira QR-coded nameplates anobatanidza kurarama kudzokorora-inodzorwa dhizaini uye spare zvikamu zvinyorwa. Kana saiti yepetrochemical muOman ichida kutsiva nekuchimbidza bhailer centrifugal blower, timu yedu yeinjiniya yakaongorora mabhaudhi enheyo aivepo, kushivirira kwemagetsi emagetsi emunharaunda, ndokuzotumira yekudonhedza-mukati neiyo pre-set VFD paramita uye nhanho yekutenderera yekuongorora. Hapana kufungidzira. Hapana kugadzirwazve kwemunda.
Chengetedzo haiwanikwe pakutumwa. Iyo inotsigirwa kuburikidza neinofanofungidzira kugadzirisa, zvikamu zvinoteedzera, uye mainjiniya akamira mukamuri yako yekudzora panguva yekutanga. Ndosaka rutsigiro rwedu runosanganisira kudzidziswa kwakanangana nekushandisa-kwete chete "mabatiro" asi "maitirwo ekuona danho rekutanga kutakura kushatisa munzvimbo dzakanyanya kunyorova Zone 2."
