Turbine shock absorber vacuum device is known from the engineering thermodynamic steam thermal cycle theory.
In order to make the thermal equipment have a higher thermal efficiency, the condenser must maintain a higher vacuum. Jet steam extractor and jet air extractor are currently the two main equipment for extracting condenser vacuum, but both of these equipment have the disadvantages of low efficiency and low compression ratio.
With the development of units in the direction of high parameters and large capacity, this type of equipment becomes uneconomical. If a combined vacuum device composed of a shock absorber and other air extractors is used, the efficiency can be greatly improved and energy consumption can be reduced.
Nine, many products in the vacuum degassing industry are often subjected to vacuum degassing in the production process. For example, clay products require vacuum degassing of clay before molding.
