Make concept to material product - successful acceptance of a new type of expand

On November 21st, 2014, experts from the Technical Institute of Physics and Chemistry at the Chinese Academy of Sciences held an acceptance review meeting for the "New Expander Development Prototype" and "New Expander Testing Platform" in the company's meeting room, and heard the development summary report and conducted After field testing, it was agreed that the project passed acceptance.

The new expander jointly developed by Pride Cryogenic and the Institute of Physics and Chemistry was the first new expander in the world and achieved a major historic breakthrough.

To verify the new expander, Pride Cryogenic developed a related test platform with a maximum circulating flow rate of 80 Nm3/h, a maximum working pressure of 20 bar and a minimum test temperature of 4.2 K. The circulating medium is helium, and the PLC and the host computer function well automatically. Control, display and collection functions.

The isentropic efficiency of the new expander reaches 57.8%, which can replace the traditional turbo expander and is applied in cryogenic equipment such as air separation equipment, liquefied natural gas equipment, and liquefaction equipment. Wide application prospects, with great economic and social benefits.
