Nheyo yekusarudza mafeni emigodhi iri muhuwandu hwemhepo, mhepo yekumanikidza, kuputika-kusapindira kwekuita, kushanda kwakanyanya, kuchengetedza redundancy, reverse ventilation, uye kuenzanisa kutenderera kuzere kwemamiriro ekushanda kwemugodhi.
1. Core parameter mamiriro (inofanirwa kuverengerwa)
1. Yangu axial kuyerera fan mhepo yemhepo Q (m³/min kana m³/h)
Kuverengera hwaro: Verenga huwandu hunodiwa hwemhepo yemugodhi (kusanganisira vashandi, gasi, huruva, kuputika, zvemagetsi uye zvemuchina, nezvimwewo) zvinoenderana ne "MT/T 634-2019".
Zvido zvekusarudza:
Main ventilator: Rated air volume ≥ Total inodiwa air volume yemugodhi × (1.05 - 1.1) (leakage, reserve margin).
Ventilator yemunharaunda: Yakatemerwa vhoriyamu yemhepo ≥ Yakaverengerwa mhepo yemhepo yekuchera kumeso × 1.1.
Kuvhara kutenderera kwese: nyore kufefetera nguva, nguva yakaoma, nhanho yekutanga yekusvika pakukwanisa kugadzira, uye gare gare kuwedzera.
2. Mine axial kuyerera fan air pressure P (Pa, total pressure)
Kuverengera hwaro: Yese mugodhi kufefetedza kuramba (kupokana kwekupokana + kupikisa kwenzvimbo) + pesvedzero yekumanikidza kwemhepo.
Zvido zvekusarudza:
Main ventilator: Rated total pressure ≥ Maximum ventilation resistance × (1.3 - 1.35) (tora muganhu wepamusoro wemigodhi yakakwirira yekudzivirira).
Ventilator yemunharaunda: Yakarongerwa kumanikidzwa kwese ≥ Kupokana kwese kwemhepo duct × 1.2.
Axial kuyerera / centrifugal kuenzanisa:
Kudzikira kuderera (<1500 Pa), mhepo yakakura yemhepo: Axial kuyerera rudzi (kutanga kune inter-shaft axial kuyerera).
High resistance (> 3000 Pa), yakadzika mugodhi: Centrifugal type.
Kupokana kwepakati, nzira yemhepo yakaoma: Yakasanganiswa kuyerera mhando.
3. Yangu axial kuyerera fan kushanda zvakanaka η
Kunyanya kushanda kweiyo huru yemhepo inofefetera ≥ 70%, uye nzvimbo yekushanda inofanirwa kunge iri mukati meiyo yepamusoro-inoshanda zone.
Isa pamberi pemhando dzesimba-rinoshanda (senge inter-shaft axial kuyerera, kusiyanisa frequency kumhanyisa regulation).
4. Mine axial flow fan simba N (kW)
Yakaverengerwa zvichienderana nehuwandu hwemhepo, kudzvanywa kwemhepo, uye kugona: N=
60 × 1000 × η Machine
×η Kutumira
Ndokumbira upe zvinyorwa zvinoda kushandurirwa nemazvo uye nekutsetseka
Q×P
Ndokumbira upe zvinyorwa zvinoda kushandurirwa nemazvo uye nekutsetseka
。
Motokari yemagetsi inofanirwa kunge iine 10% - 15% margin, uye inosiyana frequency mota (inoponesa simba uye inomhanyisa-inogadziriswa) inofanirwa kufarirwa.
Huru-hukuru-hukuru mafeni anogona kuve akashongedzerwa nembiri mota / synchronous motors.
II. Kuchengetedzwa uye Kuputika-zvisingapindire Mamiriro (zvinosungirwa)
1. Kuputika-kusingabvumire giredhi (zvinosungirwa kumigodhi yemarasha)
Migodhi yegasi: ExdⅠ (mugodhi unoputika-uchapupu mhando).
Yakakwira gasi / yakabuda migodhi: ExdⅠMb, uye yakagadzirirwa anti-static impellers uye spark-isina chimiro.
Zvese zvikamu zvemota, magetsi ekudzora, uye junction bhokisi zvinoputika-uchapupu. Midziyo isina kuputika inorambidzwa zvachose kupinda mumugodhi.
2. Chengetedzo redundancy (inosungirwa kune main ventilators)
Maseti maviri emagetsi ane huwandu hwakafanana anopihwa kune yega yega shaft yemhepo (imwe iri kushandiswa uye imwe se backup), ine imwecheteyo modhi uye yakatarwa.
Muchina wekuchengetedza unotanga mukati memaminitsi gumi.
Mapoka emuno maventilator / ventilator haafanire kushandiswa semafevha makuru.
3. Reverse ventilation capacity (inosungirwa)
A reverse ventilation mudziyo unofanirwa kuiswa, uye mafambiro emhepo anogona kuchinjwa mukati memaminitsi gumi.
Iko reverse ventilation air volume inofanira kuva ≥ 40% yehuwandu hwemhepo.
4. "Matatu Akakosha uye Makiyi maviri" kune mavheti emunharaunda
Special transformers, special switches, special cables; mhepo yekuvhara simba, gasi simba rekuvhara.
Mhepo duct: inodzoreredza moto, anti-static, ine chiyero chekuvuza ≤ 5%.
III. Mine Axial Flow Fan Mine Working Conditions uye Environmental Conditions
1. Yakazara-kutenderera kuenderana yemugodhi
Kuvhara vhoriyamu yemhepo / mhepo yekumanikidza shanduko yedanho rekutanga, yechipiri nhanho, uye nhanho yekuwedzera.
Misiyano mumaburi evhoriyamu yakaenzana yakakura, uye hupenyu hwebasa hwakareba. Sarudza rudzi mumatanho.
2. Kumanikidzwa kwemhepo yakasikwa
Kana kudzika kwetsime kuri > 400m kana mutsauko wehurefu patsime uri > 150m, sanganisira kudzvanywa kwemhepo yepanyama (±).
3. Kuchinja kwezvakatipoteredza
Hupfu huru: mapeller anopfeka, guruva-proof chisimbiso.
Damp / corrosive: anti-corrosion coating, Stainless simbi zvikamu.
Ruzha: dhizaini yakaderera-ruzha, muffler, inoenderana nehutsanana hwemaindasitiri.
IV. Kusarudza Nheyo uye Matanho
Verenga huwandu hwemhepo inodiwa: verenga huwandu hwemhepo hunoenderana neMT / T 634-2019, pamwe nemuchero.
Verenga iyo yakazara kuramba: verenga iyo yakanyanya kupokana munguva iri nyore / yakaoma yekufema, pamwe nemuganho.
Sarudza rudzi: axial kuyerera (hombe yemhepo vhoriyamu, kushomeka kushoma), centrifugal (yakakwirira kushorwa), yakasanganiswa kuyerera (pakati kuramba).
Tarisa maitiro ekuita: nzvimbo yekushanda inofanira kuwira munzvimbo inoshanda, siya 5 ° margin kune axial flow blade angle, uye centrifugal speed inofanira kuva ≤ 90% yehupamhi hwepamusoro.
Sarudza mota: kuputika-chiratidzo, simba rekuenzanisa, kusiyanisa frequency kukoshesa.
Kuchengetedzwa kwekuchengetedza: reverse ventilation, backup, matatu-specials uye maviri-kukiya, kuputika-uchapupu chitupa.
Tekinoroji uye kuenzanisa kwehupfumi: kushanda nesimba, kushandiswa kwesimba, kuchengetedza, uye hupenyu hwehupenyu hwakakwenenzverwa.
