Air knocker SK type operation principle
- When air pressure is not infused into the cylinder from the three-phase solenoid valve, the magnetic piston① attaches the Anchor plate② firmly.
- Turn on the switch to electrify the Three-phase solenoid valve. When air pressure becomes enough to detach the Magnetic piston from the Anchor plate, the Magnetic piston hits the Base plate③ with a high velocity.
- The Base plate indirectly transmits a shock to the inside of a hopper, which breaks down the bridge or formation of powder in the hopper.
- Tunr off the swith and the compressed air remaining in the Cylinder is exhaus -eted through the three-phase solenoid valve. The Magnetic piston is replaced by the Return spring④
