Amasistimu wabalandeli okususa uthuli emayini yamalahle awazona izinto ongazikhethela zona—ziyisivikelo esihamba phambili ngokumelene nesifo sokuphefumula, ingozi yokuqhuma, kanye nesikhathi sokukhiqiza. Emisebenzini yomhlaba wangempela kuyo yonke i-Shandong, i-Shanxi, ne-Inner Mongolia, sibone ukwehluleka kokukhipha umoya kubangela ukumisa okungahleliwe phakathi namahora angu-72. Ukunqwabelana kothuli kuma-motor windings? Kuqinisekiswe ezindaweni ezintathu ezihlukene zokuthunyelwa kwamalahle ngonyaka odlule. Ukungalingani kwabalandeli ngemva kwezinyanga eziyisithupha zokusebenza okuqhubekayo? Inkinga eyenzeka njalo—kuze kube yilapho o-opharetha beshintshela kumayunithi akhelwe inhloso, alinganiselayo aguqukayo anamabheringi ahlanganisiwe avalwe ngothuli.
Kungani Abalandeli Abajwayelekile Behluleka Ngaphansi Komshoshaphansi
I-axial fan yenhloso evamile ihambisa umoya. A I-Coal mine run removal fan ihambisa umoya *ngenkathi isinda* izinhlayiya ezilimazayo, umswakama ophezulu, i-methane-laden atmosphere, nokushintshashintsha kwamandla kagesi okuvamile kumagridi ezimayini akude. Ukwehluleka okuningi kulandelela emuva ekucabangeni okuthathu okungafani:
- Umcabango #1: “Uthuli luyinhlabathi nje ephuma emoyeni.” Okungokoqobo: Uthuli lwamalahle luthwala ishaja engaguquki, lunamathela ngogesi endaweni ye-impeller, futhi lucekela phansi ama-aluminium angu-0.08 mm/ngonyaka ngaphansi komthwalo oqhubekayo.
- Umcabango #2: "Ukuvikela ukuqhuma = ukubekezelela uthuli." Okuyiqiniso: Izindlu zenjini enesitifiketi se-Ex-d zivimbela ukuvutha—kodwa azivimbeli uthuli ekuvaleni amaphiko okupholisa, inyusa izinga lokushisa elijikajikayo ngo-22°C ngaphezu komkhawulo olinganiselwe.
- Umcabango #3: "I-CFM ephakeme ihlale isho ukulawula okungcono." Okuyiqiniso: Ukugeleza komoya okunyakazayo, okungenamibandela kuzungeza uthuli kabusha esikhundleni sokuluthwebula emthonjeni. Ukususwa okusebenzayo kudinga amaphrofayili esivinini afaniswa nomklamo we-hood—hhayi okukhiphayo okungavuthiwe.
Silinganise lokhu mathupha ekubuyiseleni kabusha kwango-2023 kuphaneli ye-Datong engaphansi komhlaba. Ukushintsha iyunithi yokugeleza okuxubile engu-30 kW ngochungechunge lwe-FBD (dⅠ) oluphikisayo lwe-axial fan kunqamule ukuchayeka kothuli oluphefumulayo ngo-64%—hhayi ngoba inyakazisa umoya owengeziwe, kodwa ngenxa yokuthi ijika layo lezigaba ezimbili ligcine isivinini sokuthwebula esingu->18 m/s endaweni yokungena yokugezela, ngisho noma ukumelana nesihlungi kukhuphuka.
Izidingo Ezine Zomklamo Ongaxoxiswana
Ukucacisa a I-Coal mine run removal fan kusho ukubeka phambili ubunjiniyela obufakazelwe emkhakheni kunezicaciso zekhathalogi. Nakhu okubambekayo ngaphansi komhlaba:
- Ukulinganisa okunamandla okuvalwe ngothuli: Amarotha alinganisela ku-G2.5 grade *emva* kokuhlanganiswa okugcwele—okuhlanganisa nezihlangu zothuli nama-shaft couplings—hhayi nje ama-impeller angenalutho. Ukudlidliza okungalinganiseli kusheshisa ukugqoka ngo-3.7× ezindaweni ezinothuli.
- Uhlaka olumelana nokubola: Izindlu zensimbi ezikhangayo aziphumeleli lapho i-H₂S ihlangana khona nokujiya. Abalandeli be-Titanium bamelana nokuchayeka kwegesi ene-asidi; insimbi ye-carbon steel ene-ISO 12944 C5-M isilinganiso sihlala isikhathi eside esingu-3× kunopende ojwayelekile ezimpompini ezimanzi.
- Ubuqotho bokuvikela ukuqhuma ngaphansi kwengcindezi yokushisa: Izimoto kufanele zigcine isitifiketi se-Ex-d ku-110°C ambient—okuvamile eduze namadrayivu okuthutha. Lokho kudinga ukufakwa kwe-Class H *kanye* namabhokisi etheminali angeyona ayoni ukuze kunqandwe ukusakazeka kwenhlansi ngamabhawodi akhuphukayo.
- Ukulungiswa okufinyeleleka kusevisi: Akukho ukuqaqa okudingekayo ukuze kufakwe esikhundleni. Ochwepheshe bendawo e-Xuzhou baqinisekisile ukuthi bashintshe ama-roller ayisiyingi anemigqa ekabili ku-9-19 centrifugal blower emizuzwini engu-47—besebenzisa iziklintshi ezimbili kuphela futhi kungekho crane.
Idatha Yokuthunyelwa Kwangempela: Yini Esebenza Lapho
Asikho isixazululo sendawo yonke. Uhlelo lokusebenza lubeka i-architecture:
- Izihloko zokuthuthukisa: Abalandeli be-axial abalandelanayo abawuchungechunge lwe-FBD baletha ingcindezi emile engu-12–28 kPa—okwanele ukusunduza umoya ngamamitha angu-500+ wokudonsa kuyilapho ugcina isivinini sobuso. Isakhiwo sabo sezimoto ezimbili sisusa ukushelela kwebhande futhi sivumela ukuqalisa okuhleliwe ukuze kugwenywe ukukhuphuka kwegridi.
- Indawo yokuhlala yamalahle namaphoyinti okudlulisa: Amafeni we-anti-corrosion centrifugal anama-blade agobele emuva abamba u-350–450 g/m³ ukulayisha uthuli ngaphandle kokwehla kokusebenza. Sihlole iyunithi eyodwa ngokuqhubekayo izinyanga eziyi-14 embonini yokuwasha yaseYanzhou—ukusebenza kahle okugcinwe phakathi kuka-±1.3% naphezu kwemijikelezo yokuhlanza ama-abrasive yansuku zonke.
- Iziteshi ezingaphansi komhlaba: Abalandeli be-titanium abangaqhumi bagijima buthule ku-72 dBA—ngisho noma igcwele. Ukwakhiwa kwabo okungewona uzibuthe kuqeda ukushisa kwamanje kwe-eddy eduze kwe-switchgear ephezulu.
Indaba yokudonsa amandla. Ifeni engu-45 kW esetshenziswe kabi esebenzisa u-24/7 ibiza u-$18,700/ngonyaka kugesi kuphela (ku-$0.08/kWh). Ilungelo I-Coal mine run removal fan-okulungiselelwe ukumelana nesistimu, hhayi ukukhishwa okuphezulu-kwehlisa lokho ngo-22-31% ngaphandle kokudela ukusebenza kahle kokuthwebula.
Ukukhetha Umaqondana Wakho, Hhayi Nje Umkhiqizo
Udinga ubunjiniyela bohlelo lokusebenza—hhayi ikhathalogi ye-PDF. Lapho iklayenti lase-Heilongjiang libika ukuqhekeka kwe-impeller emathanjeni alo e-desulfurization, ithimba lethu lathumela unjiniyela wenkundla ne-vibrometer ephathekayo kanye nekhawunta yezinhlayiyana. Imbangela? I-resonance ku-1,740 RPM ehambisana ne-boiler pulsation frequency. Isixazululo: Isibalo seblade esishunwe ngokwezifiso nehabhu eliqinisiwe—kulethwa ezinsukwini eziyi-11.
I-Zibo Hongcheng Fan Co., Ltd. yakha yonke into I-Coal mine run removal fan endlini—kusuka kuzigxivizo ze-titanium ezenziwe ngomshini ngokunemba ukuya kumawindi angaqhumi-ngaphansi kwemithetho yokuhlola eqondaniswe ne-ISO 9001. Iyunithi ngayinye ihlolwa ngomthwalo wamahora angu-48 ngothuli olulingiswayo olulayishwayo ngaphambi kokuthunyelwa. Azikho izinkontileka ezingaphansi kolwandle. Akukho ukuvumelana "okujwayelekile".
Ikhwalithi yomoya ngaphansi komhlaba ayimayelana nokuthobelana—imayelana nokuqhubeka. Umehluko phakathi koshintsho oluhamba luhlanzekile kanye nokumiswa kwe-alamu ye-methane ecushwe uthuli. Khetha umlandeli oklanyelwe iqiniso lemayini—hhayi isithembiso sencwajana.
