Iimeko zemizi-mveliso eziqatha azixoleli amacandelo abuthathaka. Kwiindawo zokucutshungulwa kweekhemikhali, iiyunithi ze-flue gas desulfurization, okanye ii-refineries zonxweme, abalandeli be-carbon-steel standard bahluleka kwiinyanga-i-pitting, i-crack, ibamba phantsi kwe-chloride-laden air or vapor acidic. Umbuzo wokwenene awukho ukuba umhlwa uya kubetha-yiyo nini, kwaye lingakanani ixesha lokuphumla, iindleko zokulungisa, kunye nomngcipheko wokhuseleko oluya kuzisa. Yiyo loo nto iinjineli zaseZibo Hongcheng Fan Co., Ltd. zayeka ukuyila abalandeli “abaxhathise umhlwa ngokwaneleyo”. Bakha iifeni ezichasene nomhlwa zensimbi engenasici eyenzelwe i-zero compromise: 316L izindlu zentsimbi engenasici, iishafti, iziqhoboshi kunye neziqhoboshi; i-welded seams ngokupheleleyo; imiphezulu engeyiyo; kunye ne-dynamic balancing eqinisekisiweyo kwi-ISO 1940 G2.5. Hayi njengenketho-kodwa njengesiseko.
Kutheni iStainless Steel ingekho “Ngcono nje”—Ayixoxiswanga kwizicelo eziBalulekileyo
Siye sabona iipateni ezintathu eziqhelekileyo zokungaphumeleli kwimimiselo yokubola: okokuqala, i-galvanic corrosion apho iifreyimu ze-carbon-steel zidibanisa i-impellers ezingenasici-ukudala i-micro-currents edla kwii-weld joints. Okwesibini, ukonakala kwemingxuma ngaphakathi kweeflange ezinebholiti ezivezwe kwicondensate kunye nesulfure dioxide. Okwesithathu, uxinzelelo-i-corrosion cracking kwi-fan shafts phantsi komthwalo we-thermal we-cyclic kunye nokuvezwa kwe-H₂S. Abalandeli abaqhelekileyo be-epoxy-coated bagqume le miba-de kube ukugquma iitshiphusi ngexesha lokugcinwa okanye ukukhwela ibhayisekile nge-thermal, beveza intsimbi ekrwada ngaphantsi. Ifeni yentsimbi echasene nomhlwa isusa unobangela: akukho tyatyambo lokuthotywa, akukho zintsimbi zifanayo kwizibini, akukho migibe efihlakeleyo yokubola. EZibo Hongcheng, lonke uhlobo lwe-FBD-Ⅱ fan eyenzelwe inkonzo yokukhuthaza igesi yamalahle isebenzisa i-316L engenamthungo yokudonsa kunye neebhleyidi ze-impeller ezinobuncinci be-2.5 mm ubukhulu bodonga-hayi nje ukumelana nenkungu ye-asidi, kodwa ukumelana namasuntswana abrasive ngaphandle kokubhitya ngaphantsi konyamezelo lwesakhiwo.
UkuSebenza kweLizwe lokwenyani kufuna ukuBumba iSigqibo ngasinye soYilo
Abanye banokuphikisa ukuba intsimbi estainless igqithise ukufuma okuphakathi. Kodwa idatha yasendle ixelela elinye ibali. Kwisityalo semichiza saseShandong esiqhuba umsebenzi oqhubekayo we-24/7, ifeni egqunywe yi-centrifugal yahlala iinyanga ezili-14 ngaphambi kokuba kubanjwe yintlekele ukusuka kwikloride ukuya kwigrisi. Indawo yayo yentsimbi engatyiwayo echasene nomhlwa—ukuhamba komoya okufanayo (28,000 m³/h), uxinzelelo olufanayo oluzinzileyo (3,200 Pa), umlinganiselo ofanayo wemoto (55 kW)—usebenze iinyanga ezingama-47 ngokuvalwa okungacetywanga. Ngoba? Kuba uZibo Hongcheng akatshintshi nje izixhobo. Baphinda benza ubunjineli: izindlu ezandisiweyo zokuthwala ezinezitywina ezinemilebe ephindwe kabini ezilinganiselwe kwi-IP68; i-labyrinth engathintekiyo itywina kwizandiso ze-shaft; kunye neeprofayili ze-impeller blade ezilungiselelwe isantya esisezantsi-ukunciphisa ukhukuliseko ngelixa ugcina ukusebenza kakuhle. I-9-19 i-high-pressure-stainless blower yabo, esetyenziswa ngokubanzi njenge-boiler abalandeli baseprayimari kwizityalo ezivuthayo ze-biomass, ihambisa i-84.3% ye-peak performance kwi-1,450 rpm-kungekhona ukuxhathisa ukubola, kodwa ngenxa yoqeqesho oludibeneyo lwe-thermal kunye ne-mechanical design.
UkuLungisa OkuSebenzayo-Hayi nje Amabango oNtengiso
“Ukwenziwa ngokwezifiso” kuthetha okuncinci ngaphandle kokuba ithunyelwe ngexesha, idibana ne-spec, kwaye iyasinda ekugunyazisweni. EZibo Hongcheng, ukwenziwa ngokwezifiso kuqala ngobunjineli besicelo-kungekhona amaphepha okuthengisa. Xa indawo yokunyibilikisa i-titanium ifuna iifeni ezikhusela ugqabhuko-dubulo ezikwaziyo ukumelana nomphunga wetyuwa onyibilikisiweyo kuma-450°C, iqela labo alizange lihambe ngokwemilinganiselo yegeneric. Baphonononge iingxelo zokwakhiwa kwerhasi yombane, imephu yemitha yobushushu kwizindlu zefeni, i-Inconel 625 ekhethiweyo ye-inlet cones, yongeza iziseko ezithwele ijacket yamanzi, kunye nokusebenza okuqinisekisiweyo kwi-rig yovavanyo lwangaphakathi lwe-1,200 kW-ukulinganisa ukungcangcazela, ukunyuka kobushushu, kunye nokubola koxinzelelo kwiiyure ezingama-72 phantsi komthwalo ofanisiweyo. Akukho nombolo yekhathalogu engekho kwishelufu. Akukho "phantsi kophononongo lobunjineli." Kubhalwe nje, kuyaphinda, uphumezo olungqiniweyo lwasendle. Iphothifoliyo yabo yensimbi engenastainless ye-anti-corrosion fan ibandakanya i-17 eyahlukileyo kunye ne-ATEX, i-IECEx, okanye i-CCC-Mine certification-kunye neyunithi nganye ngeenqanawa ezineengxelo zovavanyo lwezinto ezibonakalayo (MTRs), izatifikethi zokulinganisela okuguquguqukayo, kunye neegophe zokusebenza ezigcweleyo ezisayinwe yinjineli ebhalisiweyo.
Ukuthembeka Unokuqinisekisa-Ngaphambi koFakelo
Ukuthembela kuvela ekuhleni—kungekhona kwiincwadana ezinemifanekiso. Yonke intsimbi ye-anti-corrosion fan evela kwi-Zibo Hongcheng idlula kwiindawo zokukhangela ezine ezinyanzelekileyo: ukuqinisekiswa kwezinto eziluhlaza nge-spectrometer ye-XRF ephathwayo (ukuqinisekisa i-Mo ≥ 2.5%, i-Cr ≥ 16.5%, i-Ni ≥ 10.5%); ukuhlolwa komda kusetyenziswa izinto eziqinisekisiweyo zeCMM; uvavanyo olusebenzayo kwi-110% isantya esilinganiselwe kwi-30 imizuzu kunye nokubeka iliso le-vibration real-time (<0.71 mm / s RMS kwisantya sokusebenza); kunye nokuhlolwa kokuvuza kokugqibela nge-helium mass spectrometry kuyo yonke i-welded seams. Akukho nto ngenqanawa ngaphandle kwedosi yedijithali enekhowudi ye-QR enxibelelanisa neevidiyo zovavanyo, iskena se-MTR, kunye neelog zokulinganisa. Yiyo indlela okhusela ngayo impazamo ye-120,000 yeedola: ukufaka umtshini "ongenasici" kuphela ukufumana i-baseplate yi-304-hayi i-316L-kwaye iyasilela kwiinyanga ezintandathu kufuphi ne-chlorine scrubber.
I-airflow ye-industrial ayithethi malunga nokuhamba komoya-imalunga nokugcinwa kwenkqubo ukuqhubeka, ukukhusela abasebenzi, kunye nokuphepha ukusilela. Umtshini wentsimbi yensimbi engenasici ayiloziko leendleko. Ingumgca wokuqala wokukhusela kumngcipheko wenkqubo. I-Zibo Hongcheng Fan Co., Ltd. iyabakha ukuba bangafikeleli ubuncinci bemigangatho-kodwa baphile ngaphandle kwezixhobo abazisebenzisayo. Ngenxa yokuba kwiimeko ezinzima, ukuqina akukhethi. Kuphela kwengcaciso ebalulekileyo.
