Electrically driven mobile compressor or pump and mode of operation for controlling the maximum current that can be taken from a power source by the compressor or pump.

摘要

Electrically operated mobile compressor or pump, comprising at least one compressor or pump element (2) for the supply under pressure of a fluid to a network (3) of consumers (4) of such fluid under pressure; an electric motor coupled with the compressor or pump element (2) with a variable speed control and a steering box (8) for the variable speed control of the electric drive engine (5) depending on the gas and/or pressure compressed by the net flow rate (3), and a connection for the compressor connection or pump (1) on an electric power supply (7),This indicates that the steering box (8) is equipped with an algorithm (10) which can limit the electric current taken from the power supply (7) to a set or adjustable maximum value (Imax) by speed control.
