Issues with the suction volume of centrifugal compressors
Thread Content
What are the causes of poor suction volume in centrifugal compressors?
The difference between summer and winter lies in temperature; other factors such as structure also have an impact. However, for the topic raised by the original poster, it would be best to clarify under what conditions the comparison is being made
Regarding the low flow rate of the inhaled gas, it is recommended that you carry out the following checks: 1: Check the inlet flow meter to ensure it is functioning properly. 2: The filter at the compressor inlet may be clogged. 3: There may be a change in the molecular weight of the process gas. 4: The pressure at the compressor inlet might be too low. 5: Ensure that all valves along the process pipeline are in proper working condition. 6: Check the load on the drive motor; if the suction flow rate is indeed low, the load on the drive motor will decrease at a constant pressure ratio.
Recently, the inhalation volume has improved. This is because the steam temperature used in the turbine was low some time ago; the temperature of the 4.0 Mpa steam dropped to 236 degrees. Then, by increasing the temperature, the air intake volume improves.
In that case, it’s not a problem with the compressor but rather an issue of insufficient output from the turbine.
Yes, the preliminary assessment is that there is scaling on the blades inside the turbine; the low steam temperature caused some sort of \"liquid slugging\", and the scaling has been reduced to some extent. Do you think it makes sense?
Hehe, in my opinion, when it comes to driving centrifugal compressors, the key factor is the rotational speed; especially in the case of compressors driven by turbines. If the rotational speed is sufficient, then the required output can be achieved, that is, the rated power can be attained; otherwise, that won’t be possible
