【摘要】：为了解决无油涡旋压缩机的润滑问题,提出一种磁悬浮驱动式无油涡旋压缩机。基于涡旋压缩机的力学理论,充分考虑到无油涡旋压缩机工作时的实际状况,结合磁悬浮技术,设计出一种可以避免使用轴承和防自转装置的无油涡旋压缩机。通过数值计算软件对磁悬浮驱动式无油涡旋压缩机的动涡盘进行受力计算,详细分析了涡旋齿节距不同情况下动涡盘在不同转角下的受力;利用有限元分析软件对无油涡旋压缩机提供驱动力的E-I型电磁铁、U-I型电磁铁和U-U型电磁铁在不同气隙下的吸引力进行有限元仿真,并做了对比说明;最后把涡旋压缩机的受力与U-I型电磁铁的驱动力进行有效比较。结果表明:该新型涡旋压缩机在理论上是完全可以实现其正常工作,且有效避免了轴承与防自转装置的使用,同时还兼具了磁悬浮技术低磨损、无污染等特点。
[Abstract]:In order to solve the lubrication problem of oil-free scroll compressor, a magnetic levitation driven oil-free scroll compressor is proposed. Based on the mechanical theory of the scroll compressor, the actual condition of the oil-free scroll compressor is fully taken into account. Combined with magnetic levitation technology, a kind of oil-free scroll compressor which can avoid the use of bearing and anti-rotation device is designed. The dynamic vortex disk of magnetic levitation driven oil-free scroll compressor is calculated by numerical calculation software. In this paper, the force of the vortex disk at different rotation angles is analyzed in detail under the different pitch of the vortex teeth. The finite element analysis software is used to simulate the attraction of E-I type electromagnet, U-I type electromagnet and U-U type electromagnet under different air gaps, which provide driving force for oil-free scroll compressor. And made the contrast explanation; Finally, the force acting on the scroll compressor is compared with the driving force of U-I type electromagnet. The results show that the new type scroll compressor can work normally in theory. And effectively avoid the use of bearings and anti-rotation device, but also have magnetic levitation technology low wear, no pollution and other characteristics.
