h) Tighten pump and motor hold
down fasteners using a torque wrench. Apply
recommended torque given in clause 6.7,
DO NOT exceed the maximum allowable torque
values provided.
i) Run piping to the suction and discharge of the
pump. There should be no piping loads
transmitted to the pump after connection is made.
Recheck the driver and pump alignment to verify
it is still acceptable. Significant loads being
carried through the pump connections can cause
misalignment.
5 COMMISSIONING, STARTUP,
OPERATION AND SHUTDOWN
Pre start-up checks
Prior to starting the equipment mounted on a
Polybase baseplate, it is essential that the following
pump-based checks be made.
•
Pump and motor properly secured to the
baseplate
•
All fasteners tightened to the correct torque
•
Coupling guard in place and not rubbing
•
Seal support system (if used) properly secured
to the baseplate
•
Inspect the baseplate for cracks
•
Ensure the mounted equipment is ready to run
6 MAINTENANCE
It is the plant operator's responsibility to ensure
that all maintenance, inspection and assembly work
is carried out by authorized and qualified personnel
who have adequately familiarized themselves with
the subject matter by studying this manual in detail.
(See also section 1.6)
Any work on the machine must be performed when it
is at a standstill. It is imperative that the procedure
for shutting down the machine is followed.
On completion of work all guards and safety devices
must be re-installed and made operative again.
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.
Place a warning sign on the starting device:
"Machine under repair: do not start".
With electric drive equipment, lock the main switch
open and withdraw any fuses. Put a warning sign on
the fuse box or main switch:
"Machine under repair: do not connect".
Never clean equipment with flammable solvents or
carbon tetrachloride. Protect yourself against toxic
fumes when using cleaning agents.
6.1 Maintenance schedule
It is recommended that a maintenance plan and
schedule be implemented to support the equipment
mounted on a Polybase baseplate. The Polybase
baseplate does not require any maintenance, but the
following should be checked during routine
maintenance of the mounted equipment:
•
clean the surface of the baseplate to prevent long
term chemical attack from degrading the surface
(refer to 1.6.4.4 to prevent sparks when product
must comply with ATEX)
•
check that the mounted equipment is securely
fastened to the baseplate
•
inspect the surface of the baseplate for any
cracks.
6.2 Spare parts
The Polybase baseplate does not require any spare
parts unless it is damaged. If one of the threaded
inserts in the Polybase baseplate comes loose, or the
owner needs to add additional inserts to an installed
Polybase baseplate, the inserts are available from
Flowserve. A two-part industrial epoxy (Master Bond
EP21LV, Loctite E-120HP, or equivalent) is required
to bond the inserts in place. Replacement parts for
stilt mounted assemblies can also be supplied by
Flowserve.
To order spare parts
Flowserve keeps records of all products that have
been supplied. Spare parts can be ordered from your
local Flowserve Sales Engineer or from a Flowserve
Distributor or Representative. When ordering spare
parts the following information should be supplied:
1) Baseplate size
2) Motor size
3) Material of construction (color)
4) For thread repairs -- insert size and
quantity required
