Niro Soavi S.p.A
•
Close the pneumatic butterfly valve few seconds after the desludging phase
of the centrifuge has been completed;
•
Keep downstream the homogenizer a minimum backpressure of 1÷2 bar, to
allow the backflow of the homogenized product into the suction manifold
through the by-pass, when opened. Thus it is necessary to avoid a free
discharge into an open vessel or tank without pressure; if the backpressure
generated by the downstream plant is not enough to make the system work
properly, it will be necessary to install a suitable adjustable backpressure
valve.
WARNING: To ensure the complete and proper cleaning of the by-pass
circuit, it is necessary to keep the pneumatic butterfly valve (pos. A, figure
2.13.3) during the cleaning phase. Moreover, the backpressure
downstream the homogenizer must always be higher than the suction
side pressure.
