BPXH-8变频行星叶轮卸灰机的研制

Development of BPXH-8 frequency conversion unloading device with planet vane

BPXH-8变频行星叶轮卸灰机采用上下两个灰仓及组叶轮,解决了灰粉自流及卡堵现象;通过延长灰仓的密封长度,防止了灰粉结块.主轴及轴承选用20Cr钢,并进行特殊处理,过流件选用耐磨材料CoMnNb钢,提高了耐磨性,延长了寿命.实践表明,该机是火力发电厂一种新型的优质卸灰机.

After using upper and lower ash-cabins and group vane in BPXH - 8 frequency conversion ash-discharge device with plant vanes, the ash self-flow and the blocking have been resolved. The sealing length of the ash-cabins has been prolonged in order to avoid ash agglomerate. As 20Cr steel, whose surface is treated specially, is selected as the materials of the main-shafts and the bearings, and CrMoNb steel as the materails of the wear-resisting parts, their wearing quality has been raised, and their lifes have been prolonged. It is proved that the machine is good in the quality and a new kind of unloading device in thermal power plant.
