往复式压缩机迷宫密封加工过程中，为简化加工工艺，将传统迷宫密封加工成类迷宫螺旋密封。为比较类迷宫螺旋密封与迷宫密封的密封性能差异，分析类迷宫螺旋密封的密封机制，将类迷宫螺旋密封的能量耗散分成类迷宫密封能量耗散和槽向能量损失，采用CFD方法对类迷宫螺旋密封的密封性能进行数值模拟。结果表明，类迷宫螺旋密封的密封性能虽不及传统迷宫密封，但密封效果相差在5％以内，综合考虑加工工艺、经济效益等因素，采用类迷宫螺旋密封代替迷宫密封是完全可行的。

To simplify the processing technology,the labyrinth-like screw seal is used to replace the traditional labyrinth seal during the machining process of labyrinth reciprocating compressor.The sealing performance between the labyrinth seal and the labyrinth-like screw seal was compared,and the sealing mechanism of labyrinth-like screw seal was analyzed.By dividing the energy dissipation of labyrinth-like screw seal into the energy dissipation of labyrinth-like seal and the energy loss at groove direction,the sealing performance of the labyrinth-like screw seal was simulated by using CFD method.The results show that the sealing performance of the labyrinth-like screw seal is less than that of traditional labyrinth seal,but the sealing effect difference is within 5%.It is completely feasible to use the labyrinth-like screw seal instead of the laby-rinth seal with considering processing technology,economic benefit and other factors.
