Trouble
Cause
Countermeasures
Adsorption
response
is not
quick enough.
Internal capacity of the circuit on
the vacuum side is too large for
the ejector performance.
→ Reduce the internal capacity of the vacuum
circuit.
→ Change to an ejector with larger suction flow.
The set vacuum pressure for the
suction verification is too high,
making the time before
it reaches the set value longer.
Optimize the lifting force and change the setting to
have the suction verification of vacuum pressure as
low as possible.
Fluctuation of
vacuum
pressure
Supply pressure fluctuates.
Install a tank in the compressed air line on the
supply side, and reduce the air consumption of other
equipment.
The generated vacuum pressure
fluctuates, making the exhaust
noise intermittent at a certain
supply pressure range.
This is a phenomenon peculiar to ejectors which is
caused when the supply pressure is a little lower
than the standard supply pressure. → Increase or
decrease the supply pressure a small amount.
Vacuum
failure over
time (absorbs
properly
initially.)
Vacuum pressure is reduced,
due to clogging of the suction
filter (caused by dust in the
environment on the vacuum
side, sucking of foreign matter
from surface of work piece,
adsorption of humidity, etc.)
 Replace the filter element with a new one.
 Increase the number of suction filters (such as
ZFA, ZFB and ZFC)
Vacuum pressure is reduced,
because of the clogging of the
silencer (due to foreign matter
such as drainage and carbon
particles in the supply air).
Clean the supply air.
 Control the drainage.
 Add an air filter and a mist separator.
 Replace the silencer with a new one.
Vacuum pressure and/or suction
flow is reduced due to clogging
of the nozzle and the diffuser.
→ Remove foreign matter and substances sticking
to it. (Needs to be repaired.)
Mount an air filter on the supply side to prevent it
from happening again.
