Cod.
Object
Check
On starting
(category 2 and 3)
After 24 h
and
after one week
(category 2)
A
Oil leaks (oil seals,
joining surfaces, plugs,
etc.)
Visual check
Keep under control for the first 4 h:
Temporary check
B External surface
temperature
Check by thermometer
Keep under control the surface temperature until
it reaches a steady condition and verify that
Δ
T
45 K, keep the measured values to compare them
in following measurements (see 12.3)
Measure and compare
values with those
previously measured
see 12.3)
C Sound levels
Sensory check or referably by
noisemeter
Keep under control for the first 4 h.
When checking by an instrument keep the
measured values to compare them in following
measurements
Check and compare
values with those
previously measured
D Vibrations
Sensory check or preferably by
accelerometer
Keep under control for the first 4 h.
When checking by an instrument keep the
measured values to compare them in following
measurements
Check and compare
values with those
previously measured
E Gear reducer bearings
(unit pre-assembled
with vibration
monitoring device)*
Check with proper instruments
Check on starting and after 4 h.
Keep the measured values to compare them in
following measurements
Measure and compare
values with those
previously measured
F Cooling coil
Check by thermometer,
chronometer, volume measurer (or
other instruments)
Keep under control:
water temperature 20°C,
water flow rate 10
÷
20 dm3/min;
absence of water drip
Measure and compare
values with those
previously measured
G Functionality of oil/air
cooling unit
Check air temperature by
thermometer
Visual check:
– fan direction of rotation
– oil circulation
Keep under control for the first 4 h: air
temperature
40 °C;
gauge pressure > 0;
absence of oil leaks
Measure and compare
values with those
previously measured
H Functionality of oil/
water cooling unit
Check circulation of water and oil
Keep under control for the first 4 h:
water temperature
20 °C,
water flow rate 15
÷
20 dm
3
/min;
gauge pressure > 0
Measure and compare
values with those
previously measured
I Resistance
thermometers*
(oil,
bearings)
Check:
– connections to control devices
– setting of devices
– general functionality
Read value of temperature on the control device
and verify that it is lower than the established
values.
Keep under control for the first 4 h:
Measure and compare
values with those
previously measured
J Oil level control
switch*
Check:
– connections to control devices
– setting of devices
– general functionality
Keep under control for the first 4 h:
Temporary check
K Thermostat* (oil)
Check:
– setting
– electric connections to the safety
switch (auxiliary circuits, etc.)
Keep under control for the first 4 h:
Temporary check
L Cleanliness of external
surfaces
Visual check
Dust thickness
5 mm
Temporary check
M Cooling air passage
Visual check
On starting and after 4 h
Temporary check
N Screws and tightening
torque
Check by dynamo-metric wrench of
the fastening bolts (feet and flanges)
and shrink disc
Check when excessive vibration is detected and
after 4 h
Measure and compare
values with those
previously measured
O Motor absorption
Check by Watt-meter or
amp-meter
Check on starting and after 4 h. Keep the
measured values to compare them in following
measurements
Measure and compare
values with those
previously measured
The installation responsible has to verify that safety circuits using control switches and thermostats are on, run properly and
switch on at once.
Repeat a.m. check procedures:
– at any oil change
– at any exceptional maintenance
– after a continuous stop of 2 or more weeks.
