Consultation on compressors
Thread Content
1. When the pressure difference between the inlet and outlet of the compressor is equal, does a higher inlet pressure result in a higher or lower shaft power for the compressor? 2. Are a booster and a compressor the same thing, or is there a difference?
It should be the power that increases, because the flow rate increases at the same temperature
The power increases; the principle remains the same, just with no phase change occurring
Excessively high intake pressure can cause overpressure at the compressor outlet, leading to accidents
Under the same pressure difference, the lower the inlet pressure, the greater the shaft power should be, right?
I think that the greater the intake pressure, the greater the shaft power as well; since the intake pressure is higher, the flow rate increases while the cylinder volume remains constant, resulting in more work being done and thus a higher shaft power
1. The higher the shaft power. The greater the traffic, the more energy is naturally consumed.
2. Usually, by compressor I mean one that draws in air at atmospheric pressure and discharges it at a certain pressure. A supercharger introduces air at a pressure higher than atmospheric pressure and discharges it at an even higher pressure. Of course, there are also compressors that draw in air at a pressure lower than atmospheric pressure. So it’s just a matter of different names; the principle is the same: compressing gas at a certain pressure to the pressure you need.
