Blocking Protection for Pumps with SIMOCODE pro V

1 Introduction
1.1 Overview
A major problem in the conveyance of wastewater is the blockage of pumps or
clogging of sieves and grates by solid matter.
At worst, this can cause flooding of basins, undesired leakage of water or damage
to motors. At the very least, unplanned work operations will be needed to manually
eliminate the blockages.
Figure 1-1
In many cases, blockages in conveying flows can be broken up by briefly, and
sometimes repeatedly, reversing the pump direction. In order to initiate this
operation, an impending stall must be detected. Plausible criteria for this can be
derived from the electrical power supply to the pump drive.
SIMOCODE pro allows you to prevent interruptions (and therefore expensive
downtimes) in a plant and ensure optimal motor load. With SIMOCODE pro, you
can prevent faults in the system and recognize impending failures before they
happen. This application example will help you to minimize maintenance
deployments.
