equipment
Cause
- 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
- 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
- Correct the installation so that the check valve is
facing the right way to allow the desired
flow of pumped medium
- The pumped medium flow capacity is insufficient
Use a larger size
- 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/reservoir; check these traps and
the valves on the pumped medium inflow pipe system
