5.6.3. Separator hydraulic connection
The separator must be connected to the plant predisposed by the user following the indications
of the scheme of Tab. 21. All the pipe unions must be well fastened. It is advisible to connect
the separator to the plant by pipes which length is not more than 1 m. to facilitate the
disassembly of the connections when dismantling the bowl. Therefore, avoid connections (to
another machine, to the wall, etc.) that rigidly constrain the inlet-outlet unit of the machine;
this could increase vibrations level.
The solids discharge, if totally connected by a pipe, must have a sight glass that allow to see
eventual leakages. The sludge elimination plant must be realized in such a way that a
counterpressure is avoided inside it, preventing the sludge draining (fig. 5.5). These are the
features that it must have:
1) sufficiently large pipes without sharp bends and shrinkages;
2) horizontal length absence;
3) sludges must be able to freely drain into the collecting tank.
The eventually present drain traps (cover discharge,
operating water discharge, etc.) have not to be totally
connected by pipes, to check eventual leakages (fig.
5.6). These precautions must be adopted to avoid that
some liquid (water, product or sludges) could flow in
the upper part of the frame braking the rotating bowl
and/or drain in the gear chamber damaging the
bearings.
