Installation Procedure
Figure on previous page is a simplified flow sketch. For the devices such as control
valves, steam traps etc. that are not directly related to the system package, refer to
the instruction manual for each product regarding installation. Installation, inspection,
maintenance, repairs, disassembly, adjustment and valve opening/closing should be
carried out only by trained maintenance personnel.
(1) Pumped Medium:
•
Fluids that can be discharged through the
PowerTrap
are limited to steam
condensate and water.
PowerTraps
that have been specially constructed for
other specific fluids are not limited by this restriction.
(2) Motive Medium Supply Piping [Sm]:
•
The size of the motive medium supply pipe should be the same size as the
system package motive medium supply pipe connection.
•
Motive medium inlet pressure should not exceed 1.05 MPaG (150 psig, 10.5
barg).
•
Steam, compressed air, or nitrogen may be used as the motive medium.
•
When the motive medium is steam, if the application will require that the
equipment be shut down (non-operating) for periods of 2 months or longer,
install a drip leg on the motive medium supply line, and a steam trap [St] on the
drip leg. The outlet pipe from the steam trap [St] may be connected to the
exhaust pipe [Se] close to where it connects to the condensate receiver.
This measure is not necessary when the motive medium is compressed air or
nitrogen.
(3) Pressure Reducing Valve on the Motive Medium Supply Piping [Rm]:
•
When the supply pressure of the motive medium is greater than 1.05 MPaG
(150 psig, 10.5 barg), install a TLV
COSPECT
Series pressure reducing valve.
Make sure that the motive medium pressure is lower than the maximum
operating pressure of the
PowerTrap
. Use good piping practices when
selecting the installation location for
COSPECT
.
In this case, be sure to install a safety valve between the pressure reducing
valve and the
PowerTrap
.
•
When the motive medium pressure is less than 1.05 MPaG (150 psig, 10.5
barg), if a pressure reducing valve is to be installed to slow the speed of the flow,
the installation of a safety valve is not required.
•
Install the pressure reducing valve as far away from the
PowerTrap
as
possible.
When the motive medium pressure is less than 0.5 MPaG (72.5 psig, 5 barg): at
least 3 m (10 ft).
When the motive medium pressure is 0.5 MPaG or greater (72.5 psig or greater,
5 barg or greater): at least 3 m + 1 m (10 ft + 3 ft) for every 0.1 MPaG (4.5 psig,
1 barg) over 0.5 MPaG (72.5 psig, 5 barg).
•
The pressure setting on the pressure reducing valve should be between 0.05
and 0.15 MPa (7 – 20 psi, 0.5 – 1.5 bar) higher than the back pressure.
When the discharge capacity of the
PowerTrap
is insufficient for the set
motive pressure, increase this set pressure even further.
