COMPRESSOR PLANT Russian patent published in 2014 - IPC F04D25/00 

FIELD: machine building.

SUBSTANCE: invention relates to control of compressor plants. A compressor plant includes a compressor, a waste heat exchanger, an aftercooler and an air receiver, which are installed in a pressure line and connected to each other by means of main and additional pipelines, and air mains. The compressor is connected to an air filter by means of a suction pipeline. A control unit includes an atmospheric air temperature control connected to a temperature sensor located at an inlet hole of a convergent nozzle of the air filter, and a pressure control with a pressure sensor installed on the air mains; besides, both the temperature control and the pressure control contain setting and comparing units, electronic and magnetic amplifiers, as well as non-linear feedback units; with that, the compressor is connected to a drive through a rotation speed control in the form of a unit of powder electromagnetic couplings.

EFFECT: invention is aimed at reduction of power consumption for the production of pneumatic energy at maintaining consumption below the rated one and especially at negative temperatures of the atmospheric air sucked by the compressor.
