Abstract
The issues of vibration isolation for power plants along pipelines with weakly compressible working fluids using compensators have been considered in the article. It has been proposed to determine the vibration-isolating efficiency of a compensator by its vibration rigidity value at a given vibration frequency. Based on experimental data for various types of compensators, it has been revealed that the vibration rigidity increase compared to their static values can be one to two orders of magnitude or more in the studied range of vibration frequencies up to 800 Hz. It has been experimentally shown that for standard compensators, a weakly compressible working medium (water) increases vibration rigidity by an order of magnitude or more, and its flow through the compensator and pipeline further increases the transfer of vibration through the compensator. Physical and computational models of such working medium influence have been proposed and experimentally tested. Based on this, the compensator design with a vibration rigidity one hundred times less than that of a standard compensator in the frequency range up to 800 Hz has been developed and experimentally studied. It has been experimentally confirmed that to reduce the vibration transfer through the compensator, various types of working medium pressure pulsations in the compensator should be reduced, and the reasons for their occurrence have been considered. Methods have been proposed and experimentally tested to reduce vibration transfer, pressure pulsations and vibration forces using compensators with liquid, as well as using active methods.
