Evaluation of the effect of leak-tightness of cylinder-piston seals on the working process of low-speed long stroke piston units

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.
