Category Cause

E.
Faulty
PowerTrap
1. Dirt or scale is
caught in the motive
medium intake valve
or the valve is worn
2. Dirt or scale is
caught in the
exhaust valve or the
valve is worn
3. The snap-action unit
is obstructed by dirt
or scale or its
operation is
otherwise faulty
4. The float is broken
5. Dirt or scale is
caught in the GT
main valve (steam
trap) unit, resulting
in faulty valve
opening/closing
• The
PowerTrap
does not operate for long periods of
time, in spite of the fact that condensate has collected
in the condensate receiver/reservoir pipe; if there is no
sound at all of the operating medium flowing in the
motive medium intake valve and the exhaust valve, it
is possible that the
PowerTrap
is faulty
Note, however, that this phenomenon will also occur
when the motive medium pressure is less than the
back pressure
• If the
PowerTrap
does not operate for long periods
of time and the sound of the operating medium can be
heard continuously in the motive medium supply pipe,
the
PowerTrap
is faulty
Disassemble the
PowerTrap
, and inspect the
following items:
1. Raise and lower the float and check to make sure
the snap-action unit operates properly
2. Check the motive medium intake and exhaust
valves to make sure there is no dirt or scale caught
or any other abnormality
3. Check other possible factors that might hinder
operation
After performing the above inspection, repair any
defects discovered or replace the
PowerTrap
1. Dirt or scale is
caught in the
condensate inlet
check valve or the
valve is worn or
getting hung up
• The operating medium that has been supplied is
leaking from the inlet check valve, preventing the
pressure inside the trap from increasing; as a result,
the condensate is not discharged
Disassembly and inspection is required
2. Dirt or scale is
caught in the
condensate outlet
check valve or the
valve is worn or
getting hung up
• The discharged condensate has flowed back into the
PowerTrap
, causing the interval at which the unit
operates to grow shorter and reducing its discharge
capacity
Disassembly and inspection is required
3. The condensate inlet
or outlet check
valves have been
installed in the wrong
direction
• Correct the installation so that the check valve is
facing the right way to allow the desired flow of
condensate
F.
Faulty
check
valve
4. The condensate inlet
or outlet check
valves are too small
• The condensate flow capacity is insufficient
Use a larger size
G.
There is a
problem
with other
equipment
1. A large quantity of
steam is flowing into
the condensate
receiver/reservoir
• When a large quantity of steam is discharged from the
exhaust pipe or vent pipe, it may be because steam
from a blowing steam trap or an open valve has
flowed into the condensate inflow pipe system of the
condensate receiver/reservoir; check these traps and
the valves on the condensate inflow pipe system
