Is it necessary to perform pulsation analysis?
Thread Content
The discharge pressure is 5.2 MPa, the rated power is 340 KW. Is it necessary to conduct a pulsation analysis for this reciprocating compressor? ? ? Everyone says it’s a bit expensive and not worth it; I hope some experienced sea travelers can give me some advice
Pulse analysis is beneficial for the safe and stable operation of reciprocating compressors; how can it be omitted?
According to API618, for those with low outlet pressure and low rated power, it can be determined based on experience; that is, at position 1. In practice, however, many units at position 2 are not manufactured either
It is advisable to conduct pulsation analysis, as it is very important for the operation of the unit. This includes assessing the stress on the pipelines inside the unit, as well as the pulsation frequency and amplitude. Only with data available can it be determined whether the pipeline stress is within acceptable limits and whether the positions of the supports are appropriate, thereby minimizing the risk of resonance in the unit. This is extremely useful for ensuring safe equipment operation; we have encountered problems with excessive vibration on site, which renders the operation of the equipment unsafe.
There’s a whole thick book on pulsation analysis – often, by the time the pipeline design is completed in the design institute, the manufacturer has not yet dealt with the issue of pulsations. P. In my opinion, pulse analysis is more about form than substance.
First, is there a problem with your compressor? Things like vibration control, for example – if there is no reason someone thinks it’s unnecessary, then such measures are generally taken during the design and installation of compressors.
I pretty much agree with your view. It’s hard to say just how much impact it has; it’s more of a psychological comfort. In reality, one still needs to rely on experience and performance, as well as to arrange the value-added pipe racks appropriately in actual use – that’s my personal opinion.
For reciprocating compressors manufactured in accordance with API618 standards, pulsation analysis calculations are necessary.
There are three levels: 1, 2, and 3. Level 1 means it doesn’t need to be done
