DEVICE TO CONTROL OPERATION OF SUCTION DREDGE Russian patent published in 2011 - IPC E02F3/90 

FIELD: construction.

SUBSTANCE: device to control operation of a suction dredge comprises the following components joined to each other - a mode setter, a summator, an amplifier, an actuating mechanism, connected to a suction dredge, outputs of which are connected to a pressure sensor, a vacuum sensor, a pulp flow rate sensor, a force sensor on a stop rope. The device is additionally equipped with an adaptation unit, a unit for measurement of suction dredge diesel capacity and a unit for detection of suction dredge clogging. At the same time outputs of the last two units are connected to inputs of adaptation unit, in their turn there are outputs of actuating mechanism and pressure, vacuum, pulp flow and stop rope force sensors, as well as of a summator connected to remaining inputs of the adaptation unit.

EFFECT: improved efficiency.
