Purge first or conduct a single-unit test first
Thread Content
I would like to ask the seniors: Since our factory is currently under construction, should the various equipment in the air compression station be purged first and then tested individually, or tested individually first and then purged? How does one purge an air compressor? Air needs to flow through the compressor in order to carry out the purging process – how can this issue be resolved?
It doesn’t matter; do it in the way that’s most convenient for you
For the individual testing of an air compressor station alone, the order in which it is tested has little impact~~~
Generally, purging is done first, followed by pressure testing.
Blow it out first, then test run it – it’s safer that way!
First, verify the quality of the compressor’s installation. Most importantly, manually clean any residues at the welds inside the air intake filter chamber, as well as in the pipes and equipment leading from the filter chamber to the compressor itself. Clean the pipes between various stages as well. Once this is done, the compressor can be started, and this air can then be used to purge the pipes and equipment connected to the compressor. Before purging, the packing in equipment such as air-cooled towers and molecular sieves must be installed only after the purging is completed successfully. During purging, the pipes behind the compressor should be tapped gently on their walls with wooden stakes to remove any remaining residues such as slag. The quality of equipment installation before purging must be ensured, as purging is the final step. This plan is available from the equipment installation company. The key is to have proper supervision in place.
Very good! :handshake
The single-unit trial operation is organized by the contractor, while the purging is carried out by the owner; generally, the former is done first
