Effect of inlet suction volume on piston compressors
Thread Content
We are piston compressors, two-stage models used for compressing ammonia. The ammonia is compressed in the first cylinder, then passes through a cooler before entering the second cylinder. If the temperature in the first cylinder is high, will that affect the amount of gas drawn in? Will the intake volume decrease? Thank you, please share your thoughts
If the problem occurs during normal operation, then it’s not an issue related to the amount of air drawn in; rather, there might be a problem with the check valve on the cylinder, and it’s necessary to stop operations for inspection and repair. As for the temperature increase caused by water temperature, one can check the cylinder water jackets; scaling in the cooler is a factor that reduces heat exchange efficiency. High temperatures can affect the amount of air drawn in (the inflation volume).
When the temperature is high, the compression ratio decreases, which in turn affects the amount of air drawn in; temperature is a parameter that must be carefully controlled in positive displacement compressors
As the temperature rises, the density of the gas decreases and its volume increases; as a result, the compressor’s capacity declines. High cylinder temperatures lead to a reduction in the weight of the gas being delivered in the first stage. Once the hot gas cools down, its volume decreases, which in turn reduces the amount of gas entering the second stage
