Periodic Inspection and Diagnosis
There are two types of periodic inspection: the visual inspection and the disassembly
inspection.
(1) Visual Inspection
•
As a general rule, this inspection should be performed at least once every 3 months.
•
Check the following items:
a) There should be no leakage from the
PowerTrap
or from any of the
connections.
b) The PowerTrap unit should be operating cyclically (one indication being the
sharp, mechanical sound of the snap-action unit operating at the transition
between the filling and the discharge parts of the cycle). Immediately after
the end of the discharge part of the cycle and during the filling part of the
cycle, the sound of flow in the exhaust pipe should be heard. During the
pumping (discharge) part of the cycle, flow in the motive medium supply pipe
should be heard.
c) Condensate should not accumulate in the steam-using equipment, and the
temperature of the equipment should not be abnormally low.
d) There should be no condensate overflow from the overflow pipe or vent pipes.
e) There should be no continuous steam discharge through the vent pipe (it is
normal for the PowerTrap to release retained steam from the vent pipe after
motive steam forces the condensate discharge.)
f) There should not be any abnormal noise such as water hammer from the
condensate outlet pipe or the condensate recovery line while the
PowerTrap
operates.
(2) Disassembly Inspection
•
Only the
PowerTrap
unit(s) and check valves need disassembly inspection.
For the disassembly inspection, refer to the corresponding product’s instruction
manual.
