Abstract

The theoretical analysis carried out in this work showed the relevance of the topic of determining the dependencies of conditional gaps in long-stroke units on the discharge pressure for various designs of the compression stage. Significant errors in the performance of calculations, especially for large diameters of the steps, make it unacceptable to use the values of gaps obtained for the existing structures of piston units. In the future, it is necessary to carry out field tests to determine the dependencies of the gaps on the pressure and the design of the unit.The theoretical analysis carried out in this work showed the relevance of the topic of determining the dependencies of conditional gaps in long-stroke units on the discharge pressure for various designs of the compression stage. Significant errors in the performance of calculations, especially for large diameters of the steps, make it unacceptable to use the values of gaps obtained for the existing structures of piston units. In the future, it is necessary to carry out field tests to determine the dependencies of the gaps on the pressure and the design of the unit.

低速长行程活塞装置气缸-活塞密封密封性对其工作过程影响的评价

在这项工作中进行的理论分析显示了确定长冲程单元中条件间隙对各种压缩级设计的排放压力的依赖性这一主题的相关性。计算性能中的重大误差，特别是对于大直径的台阶，使得使用活塞单元现有结构的间隙值是不可接受的。今后，有必要进行现场试验，以确定间隙对压力和装置设计的依赖关系。在这项工作中进行的理论分析显示了确定长冲程单元中条件间隙对各种压缩级设计的排放压力的依赖性这一主题的相关性。计算性能中的重大误差，特别是对于大直径的台阶，使得使用活塞单元现有结构的间隙值是不可接受的。今后，有必要进行现场试验，以确定间隙对压力和装置设计的依赖关系。
