Experimental verification of the properties of pneumatic elements

Abstract

The subject of this article is experimental verification of properties of pneumatic elements. These elements have been a part of equipment for measuring of rotary air motors parameters. When comparing the measured data with the mathematical model, there were slight variations. The main objective is to verify the correct functioning of these pneumatic elements, comparing the measured results with theoretical data from the catalogs of manufacturers and determine their potential impact on the entire measuring system.

Measurement of Pneumatic Valve Flow Parameters on the Test Bench with Interchangeable Venturi Tubes and Their Practical Use

“…It also expresses the size of the valve in direct relation to the speed of the actuator. The conversion of the sonic conductance C in dm 3 s −1 •bar −1 to the effective sectional area S in mm 2 applies: S = 5 C. The flow parameters C and b contained in the data sheets often differ from their actual values, which were confirmed by the experimental determination of the characteristic of the pneumatic control valve [13]. The object of this article is to test the properties of pneumatic elements.…”
