Feedwater Pump Relief Valve
Excessive leakage from the relief valve will
result in insufficient water to the heating coil and
will result in overheating. The relief valve (Fig. 7-8)
is factory preset for the following pumps:
• C2 pump .................... 275 psi
7.3.1
Adjustment
Under certain conditions, when starting
the machine, the feed pressure may
surge sufficiently to cause the relief
valve to release a small amount of
water. The feed pressure will return to
normal, however, after the machine
heats and the system becomes
stabilized.
a. Start the machine in the FILL position and
slowly close the coil feed valve until the
relief valve begins to discharge. When the
discharge begins, check the pressure on
the feed pressure gauge.
b. To raise the pressure adjustment, turn the
adjusting screw clockwise. Similarly, to
lower the pressure adjustment, turn the
adjusting screw counterclockwise. Secure
the adjusting screw with the lock nut after
adjustment process.
It is best to make these pressure
adjustments while the feedwater pump
is off. A feedwater pump that is running
places more resistance against the
adjusting nut.
c. Fully open the coil feed valve. Regularly
inspect the relief valve for leakage during
normal operation.
7.4
Temperature Controllers (MTLC1,
MTLC2)
The MTLCs are installed in the electrical
control box.
7.4.1
Check Main Temperature Limit
Controllers
a. Remove one thermocouple lead wire from
the MTLC. See Fig. 7-9 below.
b. Verify that a shutdown occurs and an
alarm is initiated within one minute.
