Chofanizira cha 250kw mine axial flow fan, K40-8-NO26 Mine Fan, chikutumizidwa ku mabizinesi amigodi m'chigawo cha Hunan, China. Gwiritsani ntchito ma motors osaphulika omwe ali ndi mphamvu ya 380V. Moyo wautumiki wa fani ndi zaka 15.
Kuchita bwino kwambiri, phokoso lochepa, palibe hump mumayendedwe opindika
M'badwo watsopano wa K ndi DK mndandanda wa mafani opulumutsa mphamvu
1. Mwachidule
M'badwo watsopano wa K ndi DK mafani opulumutsa mphamvu adapangidwa bwino kutengera mafani opulumutsa mphamvu mumgodi. Kupyolera mu kukonzanso kwaumisiri ndi kukonzanso kamangidwe, ntchito yawo inalimbikitsidwa ndipo kukula kwa makina kunakulitsidwa. Mafani awa ali ndi magwiridwe antchito apamwamba, phokoso lotsika, magwiridwe antchito ambiri, komanso mphamvu zopulumutsa mphamvu. Kuphatikiza apo, chipangizo cha mphete chokhazikika chimayikidwa mu silinda yayikulu ya fan, ndikuchotsa ma hump pamapindikira, ndikuwonetsetsa kuti fan ikugwira ntchito mokhazikika pamikhalidwe iliyonse yokana.
Kukulitsa magwiridwe antchito a mndandanda wa mafani ndi kukwaniritsa zosowa zosiyanasiyana zazikulu, sing'anga, ndi migodi ang'onoang'ono sanali mgodi, kuti maukonde mpweya wabwino ndi otsika, sing'anga, mkulu kukana ndi lalikulu, sing'anga, mabuku ang'onoang'ono mpweya akhoza kusankha mafani waukulu, mafani wothandiza, ndi Mipikisano siteji siteshoni mafani ntchito m'dera mkulu-mwachangu, mndandanda wa mafani utenga awiri likulu chiŵerengero ndi 0.40 structural mitundu (0.40) ndi structural 0.40 mitundu (0.40) counter-rotation), zomwe ndi K40, K45 ndi DK40, DK45. Ndipo K40 imagwiritsa ntchito ma motors 4, 6, ndi 8-pole pama liwiro atatu, K45 imagwiritsa ntchito ma motors 4 ndi 6-pole pama liwiro awiri, ndipo DK40 ndi DK45 amagwiritsa ntchito ma motors 6 ndi 8-pole pama liwiro awiri motsatana.
Mwa njira iyi, mwa "kuphatikiza" kukula kwa makina ndi magawo awiri a hub, mitundu iwiri ya zomangamanga, ndi maulendo atatu mwanjira inayake, mndandanda wa mafaniwa uli ndi chiwerengero cha 93.
Masewero ndi magawo akulu aukadaulo am'badwo watsopano wa K ndi mafani opulumutsa mphamvu a DK opanda hump akuwonetsedwa mu Table 2 ndi Table 3 motsatana. Zolemera zomwe zalembedwa patebulo zimaphatikizanso kulemera kwa injini ndi diffuser yamakina onse.
Zithunzi ndi matebulo a kukula kwa mafani a K40 ndi K45 akuwonetsedwa mu Chithunzi 6 ndi Table 6 ndi 7 motsatana.
Njira yoyimira (chitsanzo) ya m'badwo watsopano wa K ndi DK mndandanda wamafani opulumutsa mphamvu ndi motere: K 40– 4 №.15
Nambala yachitsanzo cha Mining fan ndi 15,
("DJK" akuyimira chofanizira chamtundu wa mapasa) (ie m'mimba mwake mwa gudumu logwirira ntchito D = 15dr;
Hub ratio d = 0.40 Nambala ya pole ndi 4, n = 1450 r/m
