Abstract

Traditional scroll compressors are difficult to achieve oil-free operation due to the presence of a high-friction anti-rotation mechanism. This paper proposes a magnetic drive oil-free scroll compressor to solve this problem. Firstly, the structure and principle of this scroll compressor are introduced. Then the finite element analysis of the electromagnetic system was conducted; the dynamics model of the magnetic scroll compressor operating in the uncompressed state was established. Finally, the PID control of the system is performed, and simulations and experiments are carried out. Experimental results: under the 0.05 mm step signal in the X direction, the position response time of the system is 0.1 s, and the angle response time of 0.001 rad is 0.2 s. The results show that the oil-free scroll compressor has good position control response characteristics.

磁驱动无油涡旋压缩机位置响应特性分析

传统涡旋压缩机由于存在高摩擦抗旋转机构，难以实现无油运行。为解决这一问题，本文提出了一种磁力传动无油涡旋压缩机。首先介绍了涡旋压缩机的结构和工作原理。然后对电磁系统进行了有限元分析;建立了涡旋式磁力压缩机在非压缩状态下的动力学模型。最后对系统进行了PID控制，并进行了仿真和实验。实验结果:在X方向0.05 mm阶跃信号下，系统的位置响应时间为0.1 s, 0.001 rad角度响应时间为0.2 s。结果表明，无油涡旋压缩机具有良好的位置控制响应特性。
