Expander heating and purging
Thread Content
What is the method for heating and purging an expander? How can it be thoroughly cleaned to prevent ice blockages? Will reverse purging cause the expander to rotate in the opposite direction?
Regarding the cleaning of the expander, the pipeline section should be dealt with first, and then the expander should be installed. As for the subsequent cleaning, it mainly involves drying. Before starting the drying process, it is necessary to introduce shaft seal air first and then activate the oil lubrication system. The heating process should start with drying by the reverse airflow of the expander. For reference.
