Iinkqubo zeefeni zetonela ezingaqhushumba zigcina umoya uhamba apho intlantsi inokuthetha intlekele. Kwimigodi yamalahle, kwiitonela zokwenziwa kweekhemikhali, okanye kwiipaseji zenkonzo ye-oyile, ukungena komoya akukho malunga nokuthuthuzela—kumalunga nokusinda. Siye sabona abalandeli besilela phantsi koxinzelelo lobushushu, ukuvutha komlilo ngexesha le-methane spikes, okanye i-corrode emva kweenyanga ezintandathu kumoya ogcwele isulfure. Kungenxa yoko le nto iinjineli zicacisa iiyunithi zefeni yetonela yokuqhuma hayi njengokhetho-kodwa njengemfuno esisiseko.
Kutheni iiFani zeTunnel eziMgangatho zisilela kwiindawo ezinobungozi
Ukungena komoya kwindawo eyingozi kufuna ngaphezulu komthamo wokuhamba komoya. Ifuna ukhuseleko lwangaphakathi-akukho mthombo wokutshisa, akukho ndawo eshushu, akukho ndlela yokukhupha. I-axial eqhelekileyo okanye i-centrifugal tunnel fans isebenzisa ii-motor induction kunye neeterminals eziveziweyo, izindlu ezingenayo umoya, kunye neebrashi zekhabhoni ezine-arc. Kwi-Zone 1 (apho i-atmospheres yerhasi eqhumayo inokwenzeka) okanye uMmandla 2 (apho zibakho ngamaxesha athile), ezo mpawu zaphula imigangatho ye-IEC 60079-0 kunye ne-GB 3836.1 ngokuthe ngqo.
Siye savavanya abalandeli betonela abathathu abangekho kwi-shelf emoyeni we-mine oyifanisiweyo (5.5% CH₄, 22 ° C, 95% RH). Zonke zigqithile kwimilinganiselo yobushushu bomphezulu kwimizuzu engama-47. Ukusikwa kwe-thermal ephindwe kabini; enye ilayite umxube werhasi yovavanyo ngexesha lotyando lokuqalisa. Oyena nobangela? Iimotor windings ezingaqinisekisiweyo, ii-hubs ze-impeller ezingenamhlaba, kunye neziqhoboshi zeplastiki ezivelisa intlawulo yombane. Ukungaphumeleli kwehlabathi lokwenyani akuyothiyori-ibhalwe kuLawulo lwaseTshayina lwezehlo zoKhuseleko lwezeMisebenzi ukusuka ngo-2022-2023.
Yintoni eyenza uMlandeli weTonelo yoQhobo lweNyaniso?
Itonela eqinisekisiweyo yokumelana nokudubula idibanisa iileya ezine ezingaxoxisiyo: indawo evalekileyo yemoto (dⅠ okanye Ex d IIB T4), uyilo oludibeneyo olungatshiyo (hayi nje "ukumelana nentlantsi"), izinto ezihambelana neqondo lokushisa, kunye nokulinganisela okuguquguqukayo okuqinisekisiweyo kwi-110% yesantya esilinganiselwe. Uchungechunge lwe-FBD (dⅠ) olujikelezayo olujikelezayo lwe-axial flow fan-eyenzelwe ngokukodwa izihloko zomgodi wamalahle ophantsi komhlaba-lusebenzisa iimotor ezimbini ezinobungqina bokudubula ezigcinwe kwiindawo ezivaliweyo ze-aluminiyam kunye ne-0.012 mm isithuba esiphezulu sokudibanisa. I-impellers zayo zihamba kwi-1,480 rpm kodwa zihlala ngaphantsi kwe-135 ° C ubushushu bomhlaba kunye nomthwalo we-105%. Ayisiyo ikopi yokuthengisa-leyo yidatha elinganisiweyo evela kwilebhu yethu eqinisekisiweyo ye-ISO 17025.
Kodwa isiqinisekiso sisodwa asanelanga. Siye sabukela abathengi befaka abalandeli abaqinisekisiweyo kuphela ukufumana ukuphuma komoya ngokuhla ngenxa yokungahambelani kwemigudu okanye ukuhla kwamandla ombane kumgama weemitha ezingama-800. Isisombululo sokwenyani kufuneka sithathele ingqalelo izinto eziguquguqukayo zenqanaba lenkqubo: iigophe zoxinzelelo olumileyo, isiphithiphithi se-inlet, iziphumo zokufuma kwe-ambient kwi-motor insulation resistance, kunye nokuphazamiseka kwe-harmonic ukusuka kwi-variable-frequency drives. Yiyo loo nto yonke iyunithi ye-FBD ithumela ngegophe lokusebenza ngokuthe ngqo-hayi nje itshathi yekhathalogu-kwaye ibandakanya iilugi zokumisa iibhokisi ezinobungakanani obungama-35 mm² ucingo lobhedu.
Ukwenza ngokwezifiso akuyonto iLuxury-Kuyimfuneko yokuSebenza
Ubukhulu obunye-bonke abukho phantsi komhlaba. Ifeni yetonela ye-3.2 m yedayamitha yokukhukuliseka kwamalahle idinga ukutyhala okwahlukileyo, inkangeleko yengxolo, kunye nejiyometri yokunyuswa kunenye ye-5.8 m yeshafti yokufikelela kwisityalo. Sakhe ngaphezulu kwe-174 yeendlela ezahlukeneyo kwiinyanga ezingama-27 ezidlulileyo-kubandakanya imodeli ene-titanium-bladed ye-H₂S-rich flue gas ducts, ulungelelwaniso lwe-inlet-inlet yeesekethe ezihambelanayo zokungenisa umoya, kunye neenguqulelo eziguquguqukayo ezisezantsi ezinciphisa ukungcangcazela kwe-resonant kwiindonga zamatye ezitshisiweyo.
Iintambo eziphambili esizisebenzisa rhoqo:
- Iklasi yokuvala iimoto: Umgangatho we-H-class insulation, uphuculwe ukuya kwi-C-class kwi->200 °C kwi-ambient applications
- Imathiriyeli ye-Impeller: I-aluminiyam ialloy (eqhelekileyo), insimbi engenasici 316 (imekobume zekloridi), okanye iBanga lesi-7 titanium (H₂S + isantya esiphezulu)
- Ujongano lolawulo: I-RS-485 Modbus RTU efakwe ngaphambili, i-4–20 mA ingxelo ye-analog, okanye indibaniselwano yokuyeka unxunguphalo olungxamisekileyo
- Umda wesatifikethi: Iqinisekisiwe kabini kuzo zombini i-GB 3836 kunye ne-ATEX 2014/34/EU-ingqinwe yi-CNEX kunye ne-SGS
Akukho sohlwayo sexesha lokukhokela sisebenza. Umgca wethu wokuvelisa imodyuli ubamba iifreyimu ze-12 eziphambili zeemoto, iipatheni ze-8 impeller, kunye ne-5 yezindlu ezahlukeneyo-zonke zihlolwe kwangaphambili kwaye zibhalwe. Iimpawu eziqhelekileyo zitshixelwa ngaphambi kokuba kuqale ukusebenza, hayi emva kokudibana.
Ukusebenza Kwenyani Kuqala Phambi koFakelo
Ukuhanjiswa akugqitywanga. Silandele imiba yasemva kofakelo kuzo zonke iindawo ezingama-41: i-62% ilandwa kwindawo engafanelekanga, i-23% ukuya kwiintambo zobonelelo ezincinci, kunye ne-15% kwisithintelo sokungena okubangelwa luyilo olubi lotshintsho. Yiyo loo nto yonke iodolo ibandakanya inkxaso yobunjineli yesicelo sasimahla-hayi nje iincwadana zePDF. Iqela lethu lihlola itonela lakho elinqamlezileyo, ukumila kwerhasi elindelekileyo, uzinzo kumthombo wamandla, kunye nemiqobo yokufikelela kulungiso. Senza imodeli yokubola kokuhamba komoya kwiimitha ezingama-200+ zombhobho kunye nemingcipheko yokuhla kwamandla ombane weflegi phambi kokuba usike ikhonkrithi.
I-Zibo Hongcheng Fan Co., Ltd. yakha ezi yunithi kwiziko layo le-9,000 m² i-Zibo Blower Industrial Park-apho umlandeli ngamnye uthi aqhube iiyure ezingama-72 zovavanyo oluqhubekayo lomthwalo ngoxinzelelo olukwiqondo elipheleleyo, kulandele ukuskena kwe-thermographic kunye nomlinganiselo wokukhupha kancinci. Ufumana ingxelo yovavanyo esayiniweyo, hayi isitikha sesatifikethi. Kuba xa i-methane concentration ibetha i-4.3%, into ebalulekileyo ayikuthotyelwa kwamaphepha-kukuba ingaba fan iyaqhubeka ijikeleza.
Kwiinjineli ezichaza iinkqubo zabalandeli betonela ezinobungqina bokudubula, umbuzo awuthi "Loluphi uhlobo?" "Leliphi iqabane eliqondayo ukuba ukusilela ukungena komoya akuloxesha lokuphumla-kumngcipheko." Oko kuqonda kuhlala kunyamezelo lomthungo we-weld, amandla e-dielectric enamagingxigingxi, kunye nobuchule bochwephesha bokuqinisekisa ukuqhubeka kokubekwa kwindawo. Kulapho ukhuseleko lokwenyani luqala khona-kwaye apho lungaze luphele.
