Piston movement analysis for the purposes of gas impulsator diagnostics

The article describes the results of the tests carried out for the purposes of diagnostics of the control and dynamics of the piston movement, which is a component of the gas pulser. The aim of the work is to obtain knowledge about physical phenomena and processes occurring during the operation of the device. This allows to determine the causes of accelerated wear of the piston and its seals. The task of gas pulsers is to support the transport of bulk materials. These are pneumatic devices controlled by pneumatic valves. They are used in places where transported materials that create overhangs are stored (e.g., coal, bran, sand, glass). A pulse of compressed air directed from gas container trough outlet pipe into the tank causes the remaining material to peel off from the walls, which restores the free flow of the raw material.
