Helium is used in many technical applications, such as magnetic resonance imaging (MRI) machines to diagnose a variety of medical conditions. It is also used in aerospace, helping to pressurize and purge fuel tanks for rockets and satellites. These applications require high-pressure cryogenic gases, which are typically compressed by helium compressors. However, the same properties that make helium ideal for these applications also present challenges when it comes to compression. Because helium is less dense than air, it can easily escape during compression, leading to costly leaks. To combat this issue, helium compressor use special gaskets and sealants to prevent leaks.
How much does a Helium compressor cost?
Helium compressors are designed to withstand high pressures, and they must be constructed with a steel or aluminum casing that can withstand the high-pressure load of the gas. In addition, helium has a lower molecular weight than air, which means that it heats up considerably when it is compressed. Therefore, helium compressors are designed with smaller compression ratios between stages to ensure that the helium does not overheat during the compression process.
In order to overcome this problem, a new design theory of highly loaded helium compressor was proposed based on its characteristics. This theory is characterized by the fact that the highly loaded compressor can increase its Euler work by increasing both the axial velocity and minus prewhirl. This can significantly improve the performance of the helium compressor, especially in terms of its flow characteristics. Moreover, it can significantly reduce the specific power and adverse pressure gradient when backpressure increases, which is not the case with the conventional compressor.
