Inspiratory pressure
Thread Content
May I ask everyone, why does a low inhalation pressure cause the inhalation valve temperature to rise? Is it because of poor inhalation that the high-temperature, high-pressure gas in the clearance cannot be replenished by the medium, resulting in a vicious cycle that ultimately leads to an increasing temperature inside the cylinder?
With constant outlet pressure, a low inlet pressure results in a high pressure ratio, thereby leading to a higher temperature
Mm-hmm, thank you all; I kinda went off track a bit
Low inlet pressure and normal outlet pressure result in a high compression ratio, more work done, and higher temperatures
That’s correct; we have a new hydrogen generator equipped with a two-stage compressor. In the past, problems with the exhaust valve caused the pressure in the inter-stage tank to be very low, the compression ratio of the first stage was close to 1, and the suction and discharge temperatures of the second stage were extremely high, making it impossible for the unit to operate.
What is the typical limit for the exhaust temperature of compressors?
