GAS PULSER

WIPO Patent Application WO/2020/220693

A1

Disclosed is a gas pulser, comprising: a motor as well as a control system, a support frame (4), a housing, an air inlet end cover (8), an air inlet, an air outlet end cover (11), and an air outlet; an elastic connection system; and a rotor pair, which comprises a rotor provided with gas discharge holes and a solid lubrication rotor sleeve also provided with gas discharge holes, and has the function of blocking or allowing passage of gas. The solid lubrication rotor sleeve is fixed and statically mounted in the housing, the rotor is driven to rotate in the solid lubrication rotor sleeve by the motor by means of connection of the elastic connection system, the high-pressure gas pulse frequency is controlled by controlling the rotating speed of the rotor, and the intensity of a gas pulse is controlled by setting the pressure and flow of incoming gas. The gas pulser can successfully avoid the gluing failure problem of a high-speed large-diameter bimetal solid lubricating bearing and effectively reduce the wear failure problem, and can make a high-pressure gas jet generate strong intermittent pulses, thereby obtaining strong sound waves having an adjustable frequency.
