Before restarting the machine, the relevant
instructions listed in section 5, Commissioning,
start up, operation and shut down must be
observed.
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. It should include the following:
a) Any auxiliary systems installed must be
monitored, if necessary, to ensure they function
correctly.
b) Gland packings must be adjusted correctly to
give visible leakage and concentric alignment
of the gland follower to prevent excessive
temperature of the packing or follower.
c) Check for any leaks from gaskets and seals.
The correct functioning of the shaft seal must
be checked regularly.
d) Check bearing lubricant level, and if the hours
run show a lubricant change is required.
e) Check that the duty condition is in the safe
operating range for the pump.
f) Check vibration, noise level and surface
temperature at the bearings to confirm
satisfactory operation.
g) Check dirt and dust is removed from areas
around close clearances, bearing housings and
motors.
h) 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 behavior. Ensure noise,
vibration and bearing temperatures are normal.
b) Check that there are no abnormal fluid or
lubricant leaks [static and dynamic seals] and
that any sealant systems [if fitted] are full and
operating normally.
c) Check that shaft seal leaks are within
acceptable limits.
d) Check the level and condition of oil lubricant.
On grease lubricated pumps, check running
hours since last recharge of grease or
complete grease change.
e) Check any auxiliary supplies eg
heating/cooling, if fitted, are functioning
correctly.
Refer to the manuals of any associated
equipment for routine checks needed.
