摘要

为了开发高性能、高可靠性的直线冰箱压缩机

从理论上分析了影响直线压缩机固有频率的因素

通过实验研究了直线压缩机在不同排气压力和工作频率下的工作特性.研究结果表明:直线压缩机的固有频率不仅与运动组件质量和弹簧刚度有关

还受到排气压力及活塞行程的影响

随排气压力的增大而增大; 在不同的排气压力和活塞行程下

当工作频率接近固有频率时

压缩机的工作电流和输入功率最小

压缩机效率最高

工作可靠稳定.在设计直线冰箱压缩机时

为了使其高效、可靠稳定地运行

应保证额定运行工况下的固有频率与工作频率相等.

Abstract

In order to design high performance and reliability linear refrigerator compressors

the factors influencing the natural frequency of the linear compressor were analyzed theoretically

and experimental study on operating characteristics of different discharge pressure and operation frequency were conducted. The results show that the natural frequency of the linear compressor is influenced by not only mass of moving parts and spring stiffness but also discharge pressure and piston stroke

and the natural frequency increases with the discharge pressure. At the different discharge pressure and operation frequency

the compressor has the minimum working current and input power

and higher efficiency when the operation frequency being close to the natural frequency. In designing the linear refrigerator compressor

the operation frequency should be equal to the natural frequency at the rated operating condition for obtaining high performance of the linear compressor.
