Design and Application of Inflatable Sealing System for a Certain Wind Tunnel
The inflatable sealing system for a certain wind tunnel is used to isolate the air pressure environment inside and outside the gate or fill the gap between moving parts during the test,and ensure that the wind tunnel circuit can simulate the high atmospheric pressure environment up to 20 thousand meters.The base material of the ore belt is silicone rubber with reinforced fibers,and the cross section of the enclosure is concave with fixed bases on sides.it is formed by linear segmented molded vulcanization molding,the annular inflatable sealing tape is successfully developed in high and low temperature,long life,high expansion,and large scale envi-ronmental conditions,The inflation/deflation gas circuit,electromagnetic,and transmitters based on the integrated block are de-signed.The inflation and deflation control system adopts the PLC and electromagnetic and vacuum generator;The system is connected to the wind tunnel measurement and control optical fiber ring network by through the Profinet to realize the local or remote automatic control,which solves the the problems of enclosure structure,airtight leakage,and structural design of large-scale dense metal air nozzle.The system has a good application effect,high automation level,and great popularization and application value.
