Problems solved by technology

It is particularly difficult to seal when applied to highly permeable gases (such as hydrogen)
At the same time, due to the mutual friction between the sealing materials, the sealing parts need to be lubricated and cooled, and it is difficult to meet the needs of gas transportation with high requirements on gas quality and sealing

Abstract

The present invention discloses a magnetic drive high speed turbocharger, consisting of a turbo shell, a turbo rotor, a diffusing groove, a shell, an air inlet, an air outlet, a high-speed motor and a magnetic coupler. The coupler is composed of an external rotor assembly and an internal rotor assembly; the two assemblies are divided by an isolation cover which is fixed on the shell forming a sealed chamber with the shell. Besides, the external rotor assembly is connected with the high-speed motor and the internal rotor assembly is connected with the turbo rotor. The invention adopts the magnetic coupler drive, the whole pressure-improving component is arranged in a sealed shell, which eliminates sealing problems caused by dynamic sealing with no need of lubrication and cooling. The compressor is suitable for the high purity gas which has strict requirements for sealing, flammable and explosible, poisonous and baneful.

Description

technical field [0001] The invention relates to a turbocharger used for medium pressure differential gas transmission, especially for gas transmission occasions with high requirements on gas quality and sealing. Background technique [0002] Turbine compressor is the most widely used gas booster equipment among turbine compressors, and it is widely used in various sectors of the national economy, especially in mining, metallurgy, petroleum, chemical industry, energy and other fields. However, since the boost value of the turbocharger is proportional to the square of the turbine edge linear velocity, in order to obtain a larger boost, it is necessary to use a larger turbine diameter and a higher speed, or to use multi-stage turbines in series, and the manufacturing cost higher. Therefore, turbochargers are mostly used in large-flow gas delivery occasions. The equipment used for gas transportation with small flow rate and medium pressure differe...
