Pipe pressure drop and transfer bottle conveying characteristics in vertical pipe pneumatic logistics transmission system
Pneumatic logistics transmission system is widely used in medical and chemical industries.Pipe pressure drop and characteristic velocity are key parameters for vertical pipe pneumatic logistics transmission system,but related reports are few.Based on the vertical pipe pneumatic logistics transmission system constructed in the laboratory,experiments of compressed air flow conveying transfer bottle were carried out.Conveying characteristics analysis as well as the modeling of the pipe pressure drop and characteristic velocity were conducted.First,with the help of pressure drop signal analysis,high-speed camera and data processing,transfer bottle conveying characteristics were analyzed.And a method to identify the transfer bottle motion states was proposed based on the analysis of the pipe pressure drop signal.Secondly,comprehensively considering the structural characteristics of the flow channel,a pipeline pressure drop model of the vertical pipe gas flow transmission system was established,and the pipeline resistance coefficient was obtained through data regression.Finally,on the basis of force balance analysis and conservation of mechanical energy,characteristic velocity prediction models were established,which provide a new method for the transfer bottle status identification and tracking monitoring.
