XT316 - SMC ETech

NP121-A
Air Shocker
Series XT316
The air shocker is a pneumatic piston
type shock generator.
Removes plugging due to bridging or
adhesion of bulk material inside a
hopper or chute.

The model of an air shocker to be selected depends on the type,
shape, and size of the machine on which the air shocker is mounted,
as well as the degree of adhesion and plugging. However, the
following diagram will provide a guideline on selection of the type and
number of air shockers.
Example) Suppose the diameter and thickness of the hopper are 500mm
and 4mm, respectively. According to the intersection of the lines
representing the diameter and thickness, one XT316-63B should
be selected.

Piston (A)
When the 3-port solenoid valve remains OFF, the tank and piston
chamber are under atmospheric pressure, piston (A) is locked
by a spring, and thus the main passage is closed.
3) Impact
When the 3-port solenoid valve remains ON, air flows into the tank.
When the pressure reaches the specified value, the poppet opens,
the air passes through the sub-passage and flows into the piston
chamber to move piston (A), and thus the main passage opens.

Hopper
A large quantity of air accumulated in the tank flows through the
main passage into the piston chamber. Then piston (A) moves at
high speed to strike against piston (B), and thus vibration is
transmitted through the base to the hopper.
When the 3-port solenoid valve is turned OFF, the air inside the
tank and cylinder is exhausted through the exhaust port of the
solenoid valve and residual pressure exhaust port. Then piston
(A) and poppet return to their initial condition.

Mounting Method
1. The base is subjected to repeated impact load of the air shocker, so weld all the periphery completely. Intsallation
of a stiffening rib is recommended.
2. When the mounting section is thin, install a stiffening plate and weld all its periphery completely.
3. Securely tighten the air shocker with the attached bolts, spring washers, and hard-locknuts.
4. Apply wire or chain to the hook to fix the air shocker and prevent it from falling.
