The axial force value of the expander changes frequently (ATE system)
Thread Content
The plant is equipped with an expander of the Atlas type used for the refrigeration units. Since its installation, there have been frequent changes in the axial force value (ATE system), along with intermittent humming noises within the system. Help: The possible causes of this problem are. . . ? I need the help of all experts! ! ! I thank you here!
It is recommended to test the vibration spectrum along with the rotational speed. When providing the measurement results, include both the frequency-domain plot and the time-domain plot. It would be better if the testing instrument could provide a waterfall chart of the start-up and shutdown processes.
