A 250kw mine axial flow fan, K40-8-NO26 Mine Fan, iri kutumirwa kumakambani emigodhi muHunan Province, China.Shandisai mota dzinoputika-dzinopisa dzine voltage ye380V. Upenyu hwebasa rekugadzira feni makore gumi nemashanu.
Kushanda kwepamusoro, ruzha rwakaderera, hapana humps mune hunhu curve
Chizvarwa chitsva K uye DK akateedzana anochera mafeni ekuchengetedza simba
1. Muchidimbu
Chizvarwa chitsva K uye DK akateedzana emugodhi-ekuchengetedza simba mafeni akagadzirwa zvakabudirira zvichibva pamafani ekutanga emugodhi anochengetedza simba. Kuburikidza nekuvandudzwa kwehunyanzvi uye kunatsiridza zvimiro, kuita kwavo kwakakwidziridzwa uye saizi yemuchina yakawedzerwa. Iyi nhevedzano yevateveri vane hunyanzvi hwepamusoro, ruzha rwakadzika, huwandu hwekuita kwakakura, uye zvakanyanya kukosha kwekuchengetedza simba. Pamusoro pezvo, inoyerera inodzikamisa mhete mudziyo inoiswa mune huru fan cylinder, ichibvisa humps mune yehunhu curve, ichiva nechokwadi chekushanda kwakagadzikana kwefani pasi pemamiriro ese ekupikisa.
Kuwedzera mashandiro emhando yeiyi nhevedzano yevateveri uye kusangana nezvinodiwa zvemigodhi mikuru, yepakati, uye diki isiri migodhi, kuitira kuti mambure emhepo ane yakaderera, yepakati, yakakwirira kuramba uye yakakura, yepakati, mavhoriyamu madiki emhepo anogona kusarudza mafeni makuru, mafeni ebetsero, uye mafeni echiteshi chepamusoro-soro anoshanda munzvimbo yepamusoro-soro, iyi nhevedzano yevateveri inotora maviri hub reshiyo uye 0.40 mhando mbiri (0.450) hub uye 0.40 structural unit (0.40). counter-rotation), zvinoti K40, K45 uye DK40, DK45. Uye K40 inoshandisa 4, 6, uye 8-pole motors kune matatu kumhanya, K45 inoshandisa 4 uye 6-pole motors kune maviri kumhanya, uye DK40 neDK45 anoshandisa 6 uye 8-pole motors kune maviri kumhanya zvakateerana.
Nenzira iyi, ne "kubatanidza" saizi yemuchina wega wega ane maviri hub ratios, maviri ezvimiro mhando, uye matatu kumhanya neimwe nzira, iyi nhevedzano yevateveri ine huwandu hwe93 yakatarwa.
Iyo dhizaini yekuita uye yakakura tekinoroji paramita yechizvarwa chitsva K akateedzana uye DK akatevedzana emugodhi-ekuchengetedza simba mafeni asina humps anoratidzwa muTafura 2 uye Tafura 3 zvakateerana. Iwo mareferenzi akanyorwa patafura anosanganisira huremu hwemota uye diffuser yemuchina wese.
Iyo dhizaini yezvimiro uye saizi matafura eK40 uye K45 akateedzana mafeni anoratidzwa muFigure 6 uye Tafura 6 uye 7 zvakateerana.
Iyo modhi yekumiririra nzira (muenzaniso) yechizvarwa chitsva K uye DK yakatevedzana migodhi inoponesa simba mafeni ndeiyi inotevera: K 40– 4 №.15
