Explosion
proof air pump General Description These motors are of high efficiency, high
starting torque, quiet-running, low vibration and low temperature rise, and can
sustain heavy axial thrust load etc. Operation Conditions Duty Cycle: Continuous
(S1) Ambient temperature: Not over 40°C Altitude: Not over 1000meters above sea
level Field Condition: This type of motor is suitable for outdoor use in
relatively dry climates without addition protection. Cautions for mounting The
following preparation should be made before mounting: 1. Check carefully all
data on the nameplate of the motor; make sure they are strictly in agreement
with the requirements. 2. Inspect carefully that all the motor parts are
assemble in good condition and make sure that no fastenings, such as bolts and
nuts, become loosed or detached during transportation. Try to turn the motor in
the direction by hand so as to determine whether the rotor rotates freely or
not. 3. Measure the phase –to –phase and phase –to –ground insulation resistance
by using a 500V megger. The readings should not be dried out. The commonly used
drying method is to disassemble the motor and to try out it in an oven,
maintaining the temperature at about 100°C. In general, the heating process
lasts 12 to 24 hours. If there is no drying oven, incandescent lamps may be
placed inside and around 10% of the rated value to stator windings with the
rotor locked. Drying will be accomplished by the current generated heat. In
either of the later two cases, precautions must be taken not to overheat the
winding.Explosion proof air pump
