针对涡旋压缩机平衡铁随主轴旋转时产生的阻力损失问题,提出了圆角结构及机翼型结构平衡铁.运用Fluent有限元分析软件,结合滑移网格技术对平衡铁工作区域模拟,研究了 3 种不同结构平衡铁所受的压差阻力矩和摩擦阻力矩,对比分析了不同结构产生的阻力矩大小.结果表明:压差阻力矩占总阻力矩的90%以上,总阻力矩随转速的增大而增大;相对于样机平衡铁,前后端面为圆角的平衡铁总阻力矩减小了30%~50%之间;机翼型平衡铁总阻力矩减小了55%~65%之间.
Study on Influence of Balance Iron Structure on Resistance Torque of Scroll Compressor
Aiming at the problem of resistance loss caused by the balance iron of scroll compressor rotating with the spindle,the balance iron of fillet structure and wing structure was proposed.Using Fluent finite element analysis software,combined with sliding mesh technology to simulate the working area of balanced iron,the differential pressure resistance torque and friction resistance torque of three different structures of balanced iron were studied,and the resistance torque generated by different structures was compared and analyzed.The results show that the differential resistance torque accounts for more than 90%of the total resistance torque,and the total resistance torque increases with the increase of rotational speed.Compared with the prototype balance iron,the total resistance torque of the balance iron with rounded ends is reduced by 30%~50%.The total resistance torque of the wing-type balance iron is reduced by 55%~65%.
