[Dsg-rich] Discussion results on RICH air pressure and compressor from today's DSG meeting

[Tyler Lemon]

Hello,

During today's DSG weekly meeting, we discussed the problem with the RICH air pressure and compressor.

The following conclusions and recommendations were discussed:

1.) For the past few months, there has been a correlation between ambient air pressure and RICH pressure and airflows. However, this correlation does not appear to be significant since the tank pressure and airflow only changes slightly with ambient pressure.

2.) The filter at the compressor's output should be changed/drained by Hall B since its pressure drop gauge is in the red and if the filter is saturated, it may be preventing the compressor from outputting at its full capacity. The compressor will need to be powered off and the entire air-cooling system depressurized to do this.

3.) The PT used for alarms and interlocks should be replaced. Again, the compressor will need to be powered off and the entire air-cooling system depressurized to do this.

4.) It would be good to determine what routine maintenance the compressor should undergo. If any is needed, Hall B would have to arrange this with Atlas Copco.

5.) The second compressor should be powered.

Best regards,
Tyler
