Iinkqubo ze-metal ze-ventilator ayizozixhobo kuphela-ziyindlela yokuqala yokuzikhusela ngokuchasene nokuphefumla, ukuqhuma, kunye noxinzelelo lobushushu. Kwimisebenzi yehlabathi yokwenyani, sikubonile ukungaphumeleli kokungena komoya okubangela ukukhutshwa kwemeko kaxakeka-kungekhona ngenxa yokuba abalandeli bophukile, kodwa ngenxa yokuba bebengachazwanga ngokuqokelela imethane, ukulayishwa kothuli, okanye ukwahluka koxinzelelo ngequbuliso. Isiganeko sika-2023 kwimigodi ye-Shandong engabonakaliyo yaqinisekisa ukuba: i-axial fan ye-original fan yadibana neethagethi zevolumu ye-airflow ephepheni kodwa ayizange ikwazi ukugcina uxinzelelo lwe-static ngaphezu kwe-1,800 Pa xa ukuchasana kokucoca kwanda nge-40% emva kweeyure ze-72 zokusebenza okuqhubekayo. Kulapho ukuthembeka kuyeka ukuba yithiyori.
Kutheni “Ukuhamba komoya nje okwaneleyo” yiNgcinga eyingozi
Imigodi yentsimbi engaphantsi komhlaba ifuna ngaphezulu kwemveliso yevolumetric. Bafuna impendulo eguquguqukayo, imfezeko yesakhiwo phantsi kokungcangcazela, kunye nokuziphatha okungaphumeleliyo kwi-atmospheres eqhumayo. Uthotho lwe-FBD (dⅠ) olunobungqina boqhushumbo boxinzelelo loxinzelelo-i-injection counter-rotating axial flow local ventilator-esetyenziswa ngaphezulu kwe-37 yemigodi yamatye aqinileyo kulo lonke elase-China nakuMzantsi-mpuma Asia-yenzelwe ngokukodwa ukuvala loo msantsa. I-double-motor yayo, i-counter-rotation design ihambisa i-22-28% ephezulu yoxinzelelo oluphezulu kuneeyunithi ze-axial zenqanaba elinye kwigalelo lamandla afanayo. Okubaluleke ngakumbi, udidi lwayo lokuQala, iCandelo loku-1 lokuqinisekisa ugqabhuko-dubulo alufakwanga bhotshi-lwakhelwe kwijometri yezindlu zemoto, ujongano lokutywinwa kweshaft, kunye nenkqubo yokuphosa i-spark-resistant.
Kodwa ukusebenza akukho malunga neespekthi kuphela. Imalunga nokuba kwenzeka ntoni xa ubushushu be-ambient bufika kuma-52°C, ukufuma okuhambelanayo kunyukela ngaphezu kwe-95%, kwaye ukuxinwa kothuli lwe-silica kungaphezulu kwe-8 mg/m³. Iibheringi zefeni ezisemgangathweni ziyabamba. Ibhanti liqhuba isiliphu. Iimotor windings ziyancipha. Yiyo loo nto ukhetho lwentsimbi yentsimbi kufuneka luqale ngemephu yokusingqongileyo-hayi ukukhangela ikhathalogu. Siye saqaphela ukuba abathengi banciphise ixesha lokugunyazisa ngama-60% xa babesabelana ngeengxelo zohlalutyo lwerhasi yequla kunye neshedyuli yemihla ngemihla yokuthuthwa kwentsimbi phambi kokuba kuqukunjelwe ukhetho lwabalandeli. Idatha yokwenyani ibetha iingqikelelo ezihlala zikhona ngalo lonke ixesha.
Izinto eziNtathu ezingaThethwayo kuYilo lokuPhumelela kweMigodi yesinyithi
- Ingqibelelo yobungqina bokudubula kufuneka idlulele ngaphaya kwenjini. Abalandeli abanikwe umlinganiselo wezone 1 bume bendawo basasilela ukuba i-inlet ductwork ayinakuqhubekeka komhlaba okanye ukuba izithulisi zineziqhoboshi ezingakhuselwanga. Uchungechunge lwe-FBD ludibanisa iintambo eziqinisekisiweyo zokumisa ngokuthe ngqo kwi-flange ekhulayo-akukho kufakwa kwakhona kwintsimi efunekayo.
- Ukuphatha uthuli akunyanzelekanga—kuyongezeleka. Ifeni ehambisa i-12,000 m³/h ekuqaliseni ihla iye kwi-9,300 m³/h emva kweentsuku ezili-14 ngaphandle kokulungiswa ukuba ukuhluzwa kwesingeniso akwanelanga. Abalandeli be-Titanium-eyenzelwe i-high-corrosion, i-high-abrasion zones-igcina> i-94% ye-airflow elinganisiweyo ngexesha leentsuku ze-30 ngaphandle kokucoca.
- Ukulawula imiba yokusabela ngokufihlakeleyo. Iidrive frequency drives (VFDs) kufuneka zisabele ngaphakathi kwemizuzwana eyi-1.2 ukuya kwi-CO sensor triggers. Iiyunithi ezine-analog kuphela zokulawula i-loops zongeza i-4-7 imizuzwana ye-latency-ixesha elaneleyo lokugxininiswa kwe-methane ukuwela i-5% ye-LEL kwi-stopes evaliweyo.
Xa I-off-the-Shelf ingakhuselekanga ngokwaneleyo
Abanye banokuphikisa ukuba abalandeli bemizi-mveliso basebenza kakuhle kunye nezixhobo zokhuseleko ezongeziweyo. Nangona kunjalo, ukongeza iindawo ezivaliweyo zobungqina bokudubula kwi-fan ye-axial yenjongo jikelele kudala imiqobo ye-thermal, kunciphisa ukufikelela kwenkonzo, kunye nokukhupha izatifikethi zezixhobo zokuqala. Okubi kakhulu, yazisa iindawo ezintsha zokungaphumeleli: ilahleko yokucinezelwa kwe-gasket, ukuthotywa kwe-conduit seal, kunye nokudinwa kwe-wiring okubangelwa kukungcangcazela. Ukwenza ngokwezifiso akukho malunga nokunethezeka-kumalunga nokuphelisa ujongano apho umngcipheko ugxile khona.
I-Zibo Hongcheng Fan Co., Ltd. yakha lo mgaqo kwindlela yokusebenza kwayo. Xa umgodi wobhedu eYunnan wawudinga ifeni ekwaziyo ukwenza i-3,200 Pa yoxinzelelo olungagungqiyo kwi-8,500 m³/h ngelixa isebenza ngokuqhubekayo kwi-75°C yobushushu bokuphuma, iinjineli azizange zitshintshe imodeli esele ikhona. Baphinde baqhuba iiprofayili ze-blade twist kwi-ANSYS CFX, i-Inconel 625 ekhethiweyo yee-rotor hubs, kwaye yaqinisekisa ukunyamezela ukwanda kwe-thermal kwiimvavanyo zokutshisa iiyure ezili-120. Isiphumo? Iyunithi eqinisekisiweyo kwi-GB 3836.1-2021 kunye ne-ISO 8573-1 i-Class 2 ye-particulate contamination-ihanjiswe kwiiveki ze-11, kungekhona kwiinyanga ezintandathu.
Okuza emva kwe-invoyisi kubaluleke kakhulu
I-ventilator yensimbi yensimbi ayifumani ixabiso layo ngexesha lofakelo-izibonakalisa ngexesha lokutshintsha kwesithathu kwiveki ye-17. Yilapho i-harmonics ye-vibration ibonakalisa ukungahambi kakuhle, xa ukuthwala ukufudumala kweqondo lokushisa kuveza ukungahambelani kwe-lubrication, kwaye xa i-logic yokulawula ibeka i-firmware bugs. I-Zibo Hongcheng Fan Co., Ltd. ibandakanya ukulungela ukuxilongwa kude kuyo yonke i-FBD kunye neeyunithi ze-titanium-series: Inkxaso ye-Modbus TCP, i-onboard lokushisa / uxinzelelo / i-vibration sensors, kunye ne-firmware-upgradeable logic controllers. Abachwephesha bentsimi abalindeli ukuphuka-babona ukuphambuka kwi-3% yokwanda kwe-amplitude, kungekhona i-30%.
Inkonzo ayisebenzi. Kuyaqikelelwa. Iqela labo lobunjineli bezicelo liphonononga izicwangiso zokungena komoya womgodi phambi kokuba zihanjiswe-hayi ukuba zithengiswe, kodwa ukulinganisa ubude bombhobho, isiphithiphithi esibangelwa yingqiniba, okanye izilungiso zoxinano olusekwe kwindawo ephakamileyo ezitshintsha iimfuno zamandla ehashe ukuya kuthi ga kwi-11%. Loo ngqalelo ikhusela ukubuyisela intsimi ebiza imali kwaye igcina i-airways ihambelana nemigangatho yokhuseleko ye-AQ 2013-2018 yaseChina.
Ukungena komoya okukhuselekileyo kukhuseleko akukho ndawo yokulalanisa. Yonke i-ventilator yentsimbi kufuneka iphendule imibuzo emithathu ngaphambi kokuba ithunyelwe: Ngaba iyasinda kokusingqongileyo? Ngaba isabela ngokukhawuleza kwimiqondiso yesoyikiso kunexesha lokusabela kwabantu? Ngaba inkxaso yayo ye-ecosystem ilindele iindlela zokungaphumeleli—kungekhona nje ukuzibhala? I-Zibo Hongcheng Fan Co., Ltd. iphendula ewe-kungekhona njengamabango okuthengisa, kodwa njengeengxelo zovavanyo, iilogi zentsimi, kunye neerekhodi zophicotho lomntu wesithathu. Kuba ngaphantsi komhlaba, ukuhamba komoya akulinganiswa ngeecubic metres ngomzuzu. Kulinganiswa kubomi obuzinzileyo, utshintsho lugqityiwe, kwaye iimeko zikaxakeka ziyaphetshwa.
