Mine ventilation fan ukukhetha akulona uhlu lokuhlola ukuthengwa kwempahla—kuyisinqumo sobunjiniyela esibucayi ngokuphepha. Ukukhetha okukodwa okungalungile kungasho ukugxila okuphezulu kwe-methane, ingcindezi yokushisa, ukunqwabelana kothuli oluphefumulayo, noma ngisho nokushisa okuyinhlekelele endaweni eqhumayo. Sikubonile: imayini e-Inner Mongolia ithathele indawo fan yayo ye-axial egugile yafaka iyunithi engaqinisekisiwe ukuze yehlise izindleko-zingakapheli izinyanga ezintathu, amazinga e-CO akhuphuka ngesikhathi sokushintsha kweshifu. Enye indawo e-Shanxi ifake i-booster encane ye-centrifugal ngaphandle kokubala ukulahlekelwa kwe-duct friction; ukuhamba komoya kwehle ngo-38% ebusweni. Lokhu bekungekona ukwehluleka kwemishini. Bekunokungafani kwencazelo.
Qondanisa uhlobo lwabalandeli nomsebenzi wokungenisa umoya—Hhayi nje Ivolumu Yomoya
Amafeni okugeleza kwe-axial abusa umoya wendawo—ikakhulukazi eduze nobuso obusebenzayo—ngoba aletha ukugeleza komoya okuphezulu ngengcindezi emile ephansi. Kodwa "ukugeleza komoya okuphezulu" akusho lutho ngaphandle komongo. I Uchungechunge lwe-FBD (dⅠ) oluphikisana nokuqhuma kwefeni ye-axial flow, isibonelo, ifinyelela ku-20–45 m³/s ku-3,000–6,500 Pa static pressure, nama-impeller akabili azungezisa amahlangothi ahlukene. Lowo mklamo ukhansela isiyaluyalu esijikelezayo, ukhuphula ukusebenza kahle kufika ku-12%, futhi uqede isidingo sokuqondisa ama-vanes ezingxenyeni eziqinile zomhubhe. Ngokuphambene, ifeni ye-axial yesiteji esisodwa esijwayelekile yosayizi ofanayo ingase ime lapho ukucindezela okumile kudlula u-2,200 Pa—okuvamile emigwaqweni yomoya ende, egobile, noma evinjwe kancane.
Abalandeli be-Centrifugal bangena lapho ingcindezi ibaluleke ngaphezu kwevolumu: ama-shafts amakhulu, iziteshi ezikhuthazayo, noma amapayipi okukhipha i-sulfurization. I 9-19 high-pressure centrifugal blower iphatha 1,200–12,000 m³/h kufika ku-15,000 Pa—ilungele ukunqoba ukumelana nokukhuhla, izihlungi, noma ukuphakamisa okuqondile. I-impeller yayo egobile emuva isebenza ngokupholile, imelana nokwakheka kothuli, futhi igcina ukusebenza okuzinzile kuzo zonke izimo zomthwalo oguquguqukayo. Ama-root blowers? Kuphela ngokudluliswa kwegesi okunembe, engenawo umoya—njengokuphinda kujikelezwe igesi yamalahle—hhayi umoya ovamile.
Ubufakazi Bokuqhuma Akubona Inketho—Akuxoxiswana Ngayo Emayini Yegesi
Abanye o-opharetha baphatha isitifiketi sokuvikela ukuqhuma njengesithiyo samaphepha. Akunjalo. Kuyisu lokuzibamba ngokomzimba. A eqinisekisiwe I-axial flow fan yezimayini yamalahle evikela ukuqhuma kufanele ihlangabezane namazinga e-GB 3836.1–2021: izindlu ezivivinywe ukumelana nokuqhuma kwangaphakathi ngaphandle kokudluliswa kwelangabi, amazinga okushisa angaphezulu agcinwe ngaphansi kwe-T4 (135°C), kanye nokuvuleka phakathi kwezingxenye eziphendukayo nezimile ezibanjwe ukuze zikwazi ukubekezelela ama-micrometer. Silinganise izinga lokushisa eliphezulu kumayunithi angaqinisekisiwe afinyelela ku-172°C phakathi nomsebenzi oqhubekayo wamahora angu-4—ngaphezu kwemikhawulo ephephile yezingxube zomoya we-methane.
Ukuqinisekiswa komhlaba wangempela kubalulekile. Yonke iyunithi ye-FBD(dⅠ) ihlolwa ngokuyigunyaza kokushiswa kwamahora angu-72 ngaphansi komthwalo olingisiwe we-methane-rich, okulandelwa ukuthwebula isithombe esishisayo kanye nokuqinisekiswa kokucaciswa kwe-spark-gap. Asikho isitifiketi esikhishwa kuze kube yilapho umlandeli ephase kokubili ubuqotho bemishini kanye nokuhlola ukuzinza kokushisa.
Khohlwa “Usayizi Owodwa Ulingana Konke”—Ukwenza Ngokwezifiso Kuxazulula Izinkinga Zensimu Yangempela
Imininingwane ejwayelekile ihluleka ngaphansi komhlaba. Ububanzi be-duct bushintsha phakathi nokugijima? Engeza ama-cones e-tapered inlet. Umoya ogqwalile ogcwele i-H₂S emithungweni yamalahle ejulile? Cacisa izigqugquzeli ze-titanium kanye ne-epoxy ukumelana ne-asidi—hhayi nje insimbi engagqwali. Amazinga okushisa aphezulu angaphezu kuka-50°C? Thuthukisa ukufakwa kwezimoto ku-Class H futhi wengeze amaphiko okupholisa angaphandle. Sake saklama kabusha indawo yokuhlala yefenisha yomhubhe yephrojekthi kagesi we-Yunnan ngemuva kokuhlaziywa kokudlidliza kwembule ukuzwakala kwe-resonance ku-2,350 RPM-okubangelwa ukuhlangana kwe-harmonic ne-conveyor drive eseduze. Ukulungisa? Kushintshwe imvamisa yemvelo ngo-18% ngokulungiswa kokuqina kodonga nokufaka okumanzi. Ilethwa ezinsukwini eziyi-11.
I-Zibo Hongcheng Fan Co., Ltd. yakha lobu buchule enqubweni yayo. Onjiniyela abayinikezi imidwebo ekukhiqizeni—bathuthuka ngokubambisana nochwepheshe bemishini, ochwepheshe bebhalansi, kanye nabasebenzi baselebhu yokuhlola. Izicelo ezenziwe ngokwezifiso—ukuthi ukutywinwa kwe-IP68, ukuthobela kwe-ATEX Zone 1, noma ukuhlanganiswa ne-SCADA nge-Modbus RTU—kubangela ukubuyekezwa okuhlukahlukene ngaphambi kokucaphuna. Isikhathi sokuhola sihlala sibikezelwa ngoba ukwenza ngendlela oyifisayo kwenzeka ngaphakathi kwendawo efanayo engu-9,000 m² lapho kungena khona impahla eluhlaza bese kuthunyelwa ngomkhumbi amayunithi.
Bheka Ngale Kwe-Nameplate—Hlola Inqubo Esemuva Komkhiqizo
Umlandeli olinganiselwa ku-5,000 Pa akaqinisekisi i-5,000 Pa kusayithi lakho. Ukusebenza kwehlisa ukuguguleka kwe-blade, ukuguga kwe-bearing, ukushintshashintsha kwe-voltage, noma ukuhlanekezelwa kwe-inlet. Kungakho i-Zibo Hongcheng ihlola yonke iyunithi ngaphansi kwezimo zomhlaba wangempela: ukugeleza komoya okuqinisekisiwe ngohlelo lwe-pitot olulinganisiwe, ingcindezi eqinisekiswe ngama-manometer edijithali alandeleka ku-NIM, ukusebenza kahle kubalwa kusetshenziswa izindlela ezihambisana ne-ISO 5801. Umbiko ngamunye uhlanganisa ukudonsa kwangempela kwamandla—hhayi nje ukulinganisa kwezimoto—kanye nezinga lomsindo elilinganiswa imitha elingu-1 nge-ISO 3744 ngayinye.
Lesi siyalo sibaluleke kakhulu lapho ukuphila kuxhomeke ekuvumelaneni. Lapho imayini ye-metallurgical e-Gansu idinga abalandeli bokungena esikhundleni sesistimu yayo yokukhipha umoya we-sintering plant, asizange nje sifanise ukugeleza komoya. Senze imephu ama-gradients okushisa kuwo wonke ama-ductwork, salinganisa izilinganiso zokuhuzuka kwe-particle, futhi sakhetha ifeni ye-centrifugal embili-inlet enamathiphu e-ceramic-coated nama-bearings apholile ngamanzi. Manje isebenzisa amahora angu-22,000 ngaphandle kokulungiswa—kweqa okulindelwe kwe-OEM ngo-40%.
Ukukhetha ilungelo fan yokungena komoya oyiminyene iqala ngokubuza imibuzo enzima—hhayi ngamanani noma ukulethwa, kodwa mayelana nezindlela zokwehluleka, ukweqisa kwemvelo, kanye nokujula kokuqinisekisa. Kusho ukukhetha ozakwethu abahlola ngaphansi komthwalo, unjiniyela wokwehlisa isithunzi, futhi aphathe isitifiketi njenge-physics—hhayi umsebenzi wamaphepha. Ngoba emisebenzini engaphansi komhlaba, ukugeleza komoya akuyona into engabonakali. I-oxygen. Kuyi-dilution. Kuwumkhawulo phakathi koshintsho oluvamile kanye nombiko wesigameko.I-Mine Ventilation Fan
