Handling Precautions
Maintenance
Use of intermittent air blow may increase piping
temperatures. Therefore, observe the temperature for
several hours during the trial operation. Also, pay
attention to the product temperature during inspection.
The flow rate is throttled in the nozzle. If compressed air
is supplied repeatedly, the air inside the piping may
cause adiabatic compression. As a result, the
temperature inside the piping increases. In this case, if
the heat radiation to surroundings is not sufficient, the
product temperature may exceed its operating
temperature range. If compressed air is supplied under
conditions where the product temperature exceeds its
operating temperature range, this may cause the product
to break. Take the preventive measures shown below.
1) Design to reduce piping capacity.
2) Build materials or mechanisms with high heat
radiation ability into the areas around the nozzle.
3) Select a product with a wide operating
temperature range.
Example of circuit when piping temperatures increase:
Pressure of 0.5 MPa or more, Ten times per minute
5. The performance of an ejector will deteriorate due
to clogged suction filters and silencers.
High flow filters should be used, especially in dusty
locations.
If a filter is required on the release pressure side, a
different filter should be prepared.
*
It is not possible to use vacuum pressure and
positive pressure together on the same line.
6. When the element becomes clogged, stop
operation and adjust the internal pressure of the
filter to atmospheric pressure before replacing
the element.
1. Element should be replaced in either of the two
cases below.
1) When pressure drop reaches 0.1 MPa of positive
pressure or 20 kPa of vacuum pressure.
2) When the set values (flow rate, vacuum reaching
time) change.
2. During disassembly and assembly, confirm that
there are no scratches, damage, etc, to the O-ring.
3. Before using, confirm there is no leakage after
replacing elements.
4. Be sure to check that the lock mechanism is
locked securely before use.
Maintenance
1. Perform maintenance inspections according to
the procedures indicated in the operation manual.
If handled improperly, malfunction and damage of
machinery or equipment may occur.
2. Maintenance work
If handled improperly, compressed air can be
dangerous. The assembly, handling, repair, and
element replacement of pneumatic systems should
be performed by a knowledgeable and experienced
person.
3.
Drain flushing
Remove drainage from air filters regularly.
4. Removal of equipment and supply/exhaust of
compressed
When components are removed, first confirm that
measures are in place to prevent workpieces from
dropping, run-away equipment, etc. Then, cut off the
supply pressure and electric power, and exhaust all
compressed air from the system using the residual
pressure release function.
When the equipment is operated after remounting or
replacement, confirm that the equipment is operating
normally.
