wide range of inlet supply pressures, loads &
speeds.
BASIC OPERATION:
Pressurized air or natural gas enters the motor through
the inlet port. Air/gas expands through the two-stage
turbine and is exhausted to atmosphere. The turbine
drives through a gearbox (speed reduction) to the
output shaft. Indicated motor output (torque, HP,
RPM) is as measured at the shaft end.
Motor rotation is indicated “as viewed” on the shaft end
of the motor; as either RH-CW (clockwise) & LH-CCW
(counter-clockwise).
IMPORTANT
To attain maximum product life, it is important to
properly match the Motor inlet supply pressure,
power output and Motor speed to a specific load.
Regulate (if necessary) Motor supply air
pressure to the lowest possible setting
required to drive the load (pump). No more.
There are two pressure check ports on the
Motors (at inlet & exhaust) that allow users to
check the
dynamic
inlet supply pressure &
exhaust (back) pressure applied to the Motor.
Motor
exhaust
back pressure
exceeding 10
psig may reduce the life of the Motors’ rear
seals & bearings.
Dynamic pressures
are measured while Motor
is running at indicated pressure check ports
(inlet & exhaust) on the Motor housings.
1.3 PRODUCT IDENTIFICATION
The identification nameplate(s) attached to Motor
housing should indicate the following information:
Model Designation - T30-M
P/Ns (OEM &/or aftermarket p/ns) may be
present on the Motor data tag(s).
Serial Number (date manufactured code)
Maximum Operating (Inlet) Supply Pressure
Direction of Rotation
NOTE
Direction of Rotation - either left hand LH (CCW) or
right hand RH (CW) is designated from output shaft
end of the Motor.
CAUTION
Exceeding the
Maximum Operating Pressure
rating
shown on Motor nameplate or continued operation
above the
Recommended RPM Range
(speed)
indicated may result in damage to the Motor or
damage to the driven equipment (pump).
NOTE
Maximum Operating Pressure
as indicated on the
nameplate can be verified at the pressure check port
below Motor inlet port, and set
dynamically
as
described in Section 1.2.
IMPORTANT
DO NOT RUN UNLOADED or UNDERLOADED
Optimum
(correct) O
perating Supply Pressure
is
not
necessarily the Motor supply pressure observed in
your
application or the Max rated Operating Pressure.
Motor supply pressure optimization, per application,
has been proven to maximize the service life and
reliability of the Motor(s) in most applications.
NOTE
The
Proof Pressure
shown on the nameplate indicates
the maximum static pressure rating at which Motor
turbine Motor housing(s) will not burst in operation.
1.4 MOTOR OUTPUT AND
PERFORMANCE
Please refer to Performance Graphs which illustrate:
Motor Output
(shaft HP/Torque) over a range
of
dynamic
supply pressures & at speeds
(RPM) from stall to maximum free speed is
indicated on the performance graphs of each
Motor model.
Air Consumption Rates
over a range of
dynamic
supply pressures (consumption is
constant
at a given
dynamic
inlet pressure)
and is therefore cited in a separate table on
the Performance Graphs for a Motor model.
Operating speed varies by approximately
+25% when motor is run on methane gas.
Supply pressure should be adjusted
accordingly to prevent excessive Motor/pump
speed (over-speed) on gas.
Performance assumes exhaust is to
atmosphere or where Motor exhaust system
piping
minimizes back pressure, to less
than 10 psig.
