Abstract

The controllable gas vibrating system includes one exciting barrel, one piston, one guide bar, two baffle plates separately on two ends of the exciting barrel to form one sealed space together with the exciting barrel, ball valves, two motors and one control system to control the rotation of the motors. The piston is set on the guide bar for sliding relatively to the guide bar and inside the sealed space to separate the sealed space into one right gas chamber and one left gas chamber with ball valve controlled gas inlet and gas outlet each. The controllable gas vibrating system has controllable vibrating frequency, low cost and use convenience.

Description
