6.4.4 Reinserting the screw pump
Warning
The procedure described in this section is
delicate and requires a lot of care; the
manufacturer
can supply the necessary
instructions to carry it out correctly.
To carry out this procedure you can follow in reverse
order the instructions for removing the screw pump
described in the previous section 6.4.3.
The area of greatest care is the insertion of the screw
pump into its original slot, carried out before the
b
locking of the screw pump’s supporting plate.
When the screw pump is nearly completely inserted in
the ascension pipe it might be necessary to slightly
rotate it in order to make it clutch within the
transmission device.
6.5. Maintenance of mechanical parts
If detailed diagrams are not available take note of
every item and mark its location so as to avoid errors in
reassembling.
Always use spanners of the correct size.
Immediately replace screws or bolts which show signs
of wear on the threads and the heads. When screwing
and unscrewing do not use the spanners in conjunction
with
extensions to augment the torque. If
dynamometric spanners and special tools are used
verify that the calibration is appropriate for the
component.
Special care must be taken when using pneumatic or
hydraulic tools.
Before dismantling heavily oxidised components spray
them with deoxidising agents.
Before reassembling cover thinly with oil all the
coupled surfaces.
During reassembly pay particular attention to anti-slip
devices used by the manufacturer (flat washers, elastic
washers, etc.), always replacing the worn out
elements.
The ring nuts and anti-slip nuts with plastic blocking
rings must be replaced at every reassembly since the
fatigued material will deform and lose its functionality.
Attention
During maintenance procedures always use
appropriate personal protection equipment.
Use exclusively original SELMI spare
parts. The manufacturer will take no
responsibility for accidents or damages in
the case o fuse of non-original spare
parts.
