What is the product description of the helium compressor?

Our helium compressors are compact in design, reliable in quality, low in speed, long in service life and pollution-free. Helium is an expensive gas, and when used, we need to recycle it and refill it into cylinders, especially in helium balloons.

Usually the suction pressure is 0-1bar, the discharge pressure is 200bar, and the flow rate can reach 5-20nm3/hr or higher. And in the welding range of magnesium, zirconium, aluminum, titanium and other metals, helium needs to be pressurized as a protective gas.

There are mainly helium compressors, high-pressure helium compressors, liquid helium compressors, etc.

What are the technical characteristics of helium compressors?

The design of the helium compressor is oil-free, the helium refrigeration system will avoid the problem of oil contamination, and the reliability will be significantly improved. Centrifugal turbo compressors use high-speed impellers to work on the working medium to increase the pressure, without oil seals, and can be lubricated by oil-free gas bearings or magnetic bearings, completely oil-free.

The process of low-temperature refrigeration is a cycle composed of a series of thermodynamic processes. Its main function is to cool the helium working medium to the required low temperature and compensate the cold loss of the system to obtain the refrigeration capacity at low temperature or obtain liquid helium. The helium refrigeration/liquefaction cycle is a state change process in which helium is used as the working medium, so that the heat released during the low-temperature liquefaction of helium is transferred to the environment. Since it is a process of entropy reduction, a certain amount of energy is consumed.

What are the structural characteristics of helium compressors?

The centrifugal helium compressor in the liquid nitrogen temperature zone is divided into normal temperature and low temperature working parts in the overall structure, and the normal temperature part includes motor drive device, electromagnetic bearing, frequency conversion controller. The low temperature part includes the gas circulation part composed of the compressor air inlet, the working impeller, the diffuser and the volute. The main working parts of a centrifugal helium compressor are the high-speed rotating impeller and diffuser. The impeller does work on the gas, and in the flow channel of the impeller and the diffuser, the mechanical energy is converted into the gas pressure energy by the centrifugal pressure boosting effect and the speed reducing and diffusing effect. The work done by the impeller on the gas is the fundamental reason for the increase of the gas pressure. For an impeller of a certain size, the higher the rotational speed, the more energy the gas obtains, and the greater the pressure increase; the centrifugal compressor at room temperature passes through an impeller The pressure that can increase the gas is limited. If the required gas pressure is higher, multi-stage compression should be used.
