5 COMMISSIONING, START-UP,
OPERATION AND SHUTDOWN
These operations must be carried
out by fully qualified personnel.
5.1 Pre-commissioning procedure
5.1.1 Lubrication
Determine the mode of lubrication of the pump set,
e.g. grease, oil.
For oil lubricated pumps, fill the
bearing housing [3200] with correct grade of oil to the
correct level, i.e. by use of the sight glass [3856] or
constant level oiler bottle [3855].
When fitted with a constant level oiler [3855], the
bearing housing [3200] should be filled by unscrewing
or hinging back the transparent bottle and filling it with
oil. The standard Adams oilers and the Trico Watchdog
oilers are self-setting and internally vent balanced.
Where an adjustable body Denco oiler is fitted this
should be set to the height shown in the following
diagram.
The oil filled bottle should then be refitted so as to
return it to the upright position.
Filling should be repeated until oil remains visible
within the bottle. Approximate oil volumes are shown
in section 5.2.2, Bearing sizes and capacities.
Grease lubricated pumps and electric motors are
supplied pre-greased.
Where the ambient temperature is very low, special
lubricants are required. Where oil lubrication is
utilized and the ambient is less than -5 °C (23 °F)
ensure the oil pour point is at least 15 °C (27 °F)
lower than the ambient, or use oil class SAE 5W-50
or API-SJ and ensure the upper operating range of
the oil is then not exceeded. IS0 VG 46 oil is
generally selected for an initial lubrication schedule.
Other drivers and gearboxes, if appropriate, should
be lubricated in accordance with their manuals.
