Gas pulse generator

Abstract

The invention provides a gas pulse generator. The gas pulse generator comprises a motor, a control system, a support frame, a shell body, a gas inlet end cover, a gas inlet port, a gas outlet end cover and a gas outlet port. The gas pulse generator is characterized by further comprising an elastic connection system and a rotor pair, wherein the rotor pair comprises a rotor provided with a gas exhaust hole and a solid lubrication rotor sleeve also provided with a gas exhaust hole, and has a gas check opening-closing function; the solid lubrication rotor sleeve is fixedly and statically installed in the shell body; the rotor is driven to rotate by the motor in the solid lubrication rotor sleeve through the connection of the elastic connection system; the pulse frequency of high-pressure gasis controlled by controlling the rotational speed of the rotor; and the strength of gas pulses is controlled by setting the pressure and flow rate of the gas which flows in. The gas pulse generator iscapable of successfully avoiding the problem of gluing failure of a high-speed large-diameter double-metal solid lubrication bearing and effectively alleviating the problem of wear failure, capable of effectively reducing the heating amount of the double-metal oil-free bearing, capable of enabling high-pressure gas jet to generate strongly discontinuous pulses and then obtaining a strong sound wave with an adjustable frequency, and capable of being used in but not limited to the fields of strong sound wave rain enhancement, fog dispersal, dust removal and the like.

Description

technical field [0001] The invention relates to a gas pulser, in particular to a gas pulser applied in the field of strong sound waves. Background technique [0002] In the prior art, gas pulsers (gas pulse generators) have been widely used, and many studies have been conducted. For example, a method of obtaining gas pulses by controlling the high-pressure gas source switch at high speed through a solenoid valve is proposed, and a mechanical rotary pulse gas generator is also proposed. [0003] For the method of obtaining gas pulses through electromagnetic valves, it is generally believed that there are disadvantages such as unreliable sealing and leakage, limited frequency of high-frequency switching of electromagnetic valves, narrow application range, short life, and poor working reliability. [0004] For mechanical rotary pulse gas generators, generally speaking, the structure of the prior art is relatively complicated. [0005] References: Patent Documents CN107402194A...
