Cause
Corrective Measure
F.
Faulty
check valve
1. Dirt or scale is caught in the
pumped medium 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 pumped medium is not discharged
Disassembly and inspection is required
2. Dirt or scale is caught in the
pumped medium outlet
check valve or the valve is
worn or getting hung up
- The discharged pumped medium 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 pumped medium 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 pumped medium
4. The pumped medium inlet or
outlet check valves are too
small
- The pumped medium 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 receiver
- 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 pumped medium
inflow pipe system of the receiver; check these
traps and the valves on the pumped medium
inflow pipe system
