Pneumatic Capsule Transport

The main advantages of the pneumatic capsule transport are: the high speed, ecological safety and the possibility to fully automate the movement. The objective of the work is to analyze the possibility to use the pneumatic capsule transport for transportation of different cargoes. The theoretical method of capsule pneumatic transport characteristics, depending on the tube material, includes the mathematical model with different types of friction. This model is based on Newton's second law of motion. The experimental device consists of a t-piece that is connected to the tube and vacuum pump through three-way valves. The capsule passes by one of the ultrasonic detector and starts the timer. The timer goes off when the capsule passes by the second detector. Specially designed program gives the opportunity to check the differential pressure in real-time mode and to get the data about the time movement of the capsule. The experimental research showed that the theoretical model can be used to calculate different types of the pneumatic capsule transport; the experimental model can be used to get kinematic data of the capsule movement and to determine the friction coefficient; the device and the software gives the opportunity to continue the research of the possibility to use the capsule pneumatic transport for transportation of different cargoes.
