Pneumatic shake devices
Spring knocker
|
|
Pneumatic knocker could be used for bulk material release if the bulk material was adhesed on walls of tubes or filling hopper. Compared to ball vibrator, knocker can be used for materials which solidify by intensive shedding; in this case individual shakes are well-proven. The principe is simple: by presurize of air chamber the spring is pre-tensioned and by air exhausting the spring causes the impact. This system should be used, when there is no sufficient flow rate in the line for standard pneumatic knockers without springs. |

Reccommended connection
The 3/2 valve is suitable for knocker control. The force of knocker does not depend on distance between knocker and valve. We reccommend to mount the valve outside, where the knocker's shocks couldn't reach the valve. | ||
Attention: knocker is designed for make shocks only by movement of piston towards to front cap with flange! Do not allow to make shocks during piston return movement in any case! It may be the cause of permanent damage of end cap of knocker! |
