What should be paid attention to when using a helium compressor?

Helium is 86% less dense than air. This means that helium compressors must be built to extremely tight tolerances to efficiently compress helium without excessive leakage. Additionally, helium gas releases a lot of heat when compressed, and the compressor must be able to absorb and dissipate that heat. Therefore, for larger helium compressors, water cooling is required to improve cooling efficiency.

Typical helium applications include recovery and compression systems for liquid cooling in research facilities, particle accelerators, nuclear medicine, aerospace and military missile applications. Helium recovery and compression is also used in general industrial applications, commercial gas filling plants, heliostat applications and helium extraction.


How does a helium compressor work in the process?

The working principle of the helium compressor mainly includes two aspects: gas liquefaction and gas separation.

Gas liquefaction is realized by organizing liquefaction equipment according to the liquefaction cycle. The main liquefaction cycles are the Linde liquefaction cycle and the Claude liquefaction cycle.

The helium compressor utilizes the throttling effect of the throttling valve to liquefy the feed gas cycle. The raw material gas at normal pressure p1 and normal temperature T1 is compressed in the compressor from state 1 to state 2 at the same temperature, and the corresponding pressure is p2. It is cooled down to state 3 by the heat exchanger, and then depressurized by the throttle valve, and expanded to the state of equal enthalpy. 4. At this time, part of the gas is converted into liquid and discharged from the liquid reservoir; the unliquefied part of the gas is reheated in the heat exchanger to state 1, thereby forming a thermodynamic cycle.


What are the structural characteristics of the helium compressors?

1. helium compressors offer a wide range of helium operating pressures and flow rates for a variety of cryopump and cryogenic cold head applications.

2. helium compressors are available in high pressure, low pressure, water-cooled and air-cooled models;

3. helium compressors are the central source of ultra-high-purity helium in closed cycle systems.

4. helium compressors offer easy maintenance, proven reliability and optional remote control capabilities.

5. In addition, the helium compressor uses a scroll compressor instead of a piston compressor in competitor products. Scroll-based compressors provide greater reliability and energy efficiency, and greatly improve reliability.
