Periodic Inspection And Diagnosis - TLV PowerTrap GP14-B Manuel D'utilisation

• The GP14-B can discharge approximately 30 liters (8 U.S. gal) of pumped
medium for each discharge operation.
The amount of time required for each discharge operation will be between 3 and 30
seconds, depending on the back pressure and the motive medium pressure.
(2) If an error such as a leak or water hammer occurs after beginning PowerTrap operation,
shut off the valves immediately in the following order:
valve [Vm] on motive medium supply pipe → pumped medium inlet valve [Vi] → pumped
medium outlet valve [Vo] → valve [Ve] on exhaust pipe
(3) Whenever any type of malfunction is suspected in the PowerTrap, refer to the
"Troubleshooting"section on page 30.

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-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) Pumped medium should not accumulate in the (steam-using) equipment, and the
temperature of the equipment should not be abnormally low.
d) For open systems, verify that an overflow pipe from the receiver is installed.
e) For open systems, no steam should be seen flowing out through the vent pipe.
f ) There should not be any abnormal noise from the pumped medium outlet pipe or the
pumped medium recovery line when the PowerTrap operates.
(2) Disassembly Inspection
• Refer to the "Disassembly/Reassembly" section on pages 21 - 29.
• As a general rule, this inspection should be performed at least once every 2 years.
• When inspecting the interior of the unit, check the following items:
a) Make sure the push rod does not catch on anything during snap-action (the up-down
movement of the push rod) and moves smoothly as the float rises and falls.
b) Make sure the valve shafts in the intake (motive medium) and exhaust valves move up
and down smoothly. The gap between the stem of the closed intake (motive medium)
valve and the push plate should be within specified range. The exhaust valve will have
some movement when open, but should be stable when closed.)
c) Make sure the float is not damaged and has not filled with water.
d) Make sure all nuts and bolts are properly installed and fastened.
e) Check to make sure that there is no foreign matter sticking to the shafts and levers of
any of the units, and make sure there is no abnormal wear.
• When reassembling, be sure to replace the body and cover gaskets with new gaskets.
• Also replace any parts that are broken or show serious wear.
• If any parts require replacement, refer to "Replacement Parts" on page 22.
