Oil and grease leaks may make the ground
slippery. Machine maintenance must always
begin and finish by cleaning the ground and the
exterior of the machine.
If platforms, stairs and guard rails are required for
maintenance, they must be placed for easy access to
areas where maintenance and inspection are to be
carried out. The positioning of these accessories must
not limit access or hinder the lifting of the part to be
serviced.
When air or compressed inert gas is used in the
maintenance process, the operator and anyone in
the vicinity must be careful and have the
appropriate protection.
Do not spray air or compressed inert gas on skin.
Do not direct an air or gas jet towards other people.
Never use air or compressed inert gas to clean
clothes.
Before working on the pump, take measures to
prevent an uncontrolled start. Put a warning board
on the starting device with the words:
"Machine under repair: do not start".
With electric drive equipment, lock the main switch
open and withdraw any fuses. Put a warning board
on the fuse box or main switch with the words:
"Machine under repair: do not connect".
Never clean equipment with inflammable solvents
or carbon tetrachloride. Protect yourself against
toxic fumes when using cleaning agents.
6.2 Maintenance schedule
It is recommended that a maintenance plan
and schedule is adopted, in line with these User
Instructions, to include the following:
a) Any auxiliary systems installed must be
monitored, if necessary, to ensure they function
correctly.
b) Check bearing lubricant level, and if the hours
run show a lubricant change is required.
c) Check that the duty condition is in the safe
operating range for the pump.
d) Check vibration, noise level and surface
temperature at the bearings to confirm satisfactory
operation.
e) Check dirt and dust is removed from areas
around close clearances, bearing housings and
motors.
f) Check coupling alignment and re-align if
necessary.
Our specialist service personnel can help with
preventative maintenance records and provide
condition monitoring for temperature and vibration
to identify the onset of potential problems.
If any problems are found the following sequence
of actions should take place:
a) Refer to section 7, Faults; causes and
remedies, for fault diagnosis.
b) Ensure equipment complies with the
recommendations in this manual.
c) Contact Flowserve if the problem persists.
6.2.1
Routine inspection (daily/weekly)
The following checks should be
made and the appropriate action taken to remedy
any deviations:
a) Check operating behaviour. Ensure noise,
vibration and bearing temperatures are normal.
b) Check the level and condition of oil lubricant.
On grease lubricated pumps, check running
hours since last recharge of grease or complete
grease change.
c) When "sealed for life" bearings are fitted it is
recommended that they are renewed every
12 000 hours running life or every 2 years,
whichever is the sooner.
d) Check any auxiliary supplies eg heating/cooling
(if fitted) are functioning correctly.
Refer to the manuals of any associated
equipment for routine checks needed.
e) Pumps having ferrous wetted
components may rust internally if stood for
periods longer than say 2 weeks. In such cases
it is recommended that the pump shaft be turned
a few revolutions at least once a week to break
any rust or algae that may have built up in the
clearances between rotating parts. On units
where the shaft is accessible it may be turned
by hand. In other cases a flick of the starter is
permissible after ensuring that the pump casing
is full of liquid to prevent bearings etc running
dry.
6.2.2
Periodic inspection (six monthly)
a) Check foundation bolts for
security of attachment and corrosion.
b) Check pump running records for hourly usage
to determine if bearing lubricant requires
changing.
