Seeking help regarding compressor efficiency
Thread Content
The designed compressor power is 3,400 kilowatts for a flow rate of 810,000 cubic meters per hour; currently the operating flow rate has dropped to 400,000 cubic meters per hour. Could the efficiency be too low? Is it necessary to replace it with a smaller compressor? Experts, please help analyze it
A single unit with an air flow rate of 810,000 cubic feet per hour doesn’t seem to exist in the world yet. Based on the power of the motor used in such a system, the exhaust volume should be around 35,000 standard cubic feet per hour; the original poster might want to verify this further
Centrifugal types cannot do this; under normal centrifugal design conditions, the operating condition adjustment range is between 75% and 100%
What about a reciprocating type? Would that work? Could its efficiency be too low under light operating conditions, making it uneconomical?
I don’t know much about reciprocating types; in my opinion, the volumetric efficiency decreases when the back pressure remains constant
According to what the poster said, the efficiency of the piston machine must be reduced. It is recommended to shut down two units and keep two running.
Is there a leak in the air valve? The inflation volume has decreased so much
I misunderstood what the original poster meant. The design called for over 800,000 square meters, but only half of that was actually used; using excessive resources for such a small scale results in low efficiency.
1. Reciprocating compressors generally come in several versions for adjusting flow rate, such as 50%, 75%, 100%, etc. 2. When operating outside the designed conditions, the volumetric efficiency also changes. 3. To determine whether a reciprocating compressor can operate for an extended period at lower flow rates, it is necessary to consult the manufacturer; for example, it is important to check whether the reverse angle meets the requirements. 4. If there is a spare reciprocating compressor with a lower flow rate but that still meets the required pressure specifications, switching to use that compressor is a good option
