COMPRESSOR OR PUMP EQUIPPED WITH A CONTROL FOR THE REGULATION OF THE WORKING RANGE AND WORKING METHOD APPLIED FOR THE REGULATION

摘要

Compressor or pump, comprising at least one compressor or pump element (2) for pressurised supply of a fluid to a network (3) of consumers (4) of such pressurised fluid; a motor (5) coupled with the compressor or pump element (2), wherein the compressor or pump (1) is designed to operate within a certain nominal working range determined by the nominal control ranges between maximum and minimum allowed values of the control parameters of the compressor or pump (1) in nominal working conditions and whereby the compressor or pump is equipped with a control (8) having a basic control (8a) for the nominal regulation of one or more control parameters (Q, pw) as a function of a desired, set working point (14) of the compressor within the nominal set working range of the compressor or pump (1), set during design, characterised in that the control (8) is further provided with an additional control function (8b) for static or dynamic adjustment of the working range limit values, whereby the nominal control range (11, 17) of one or more control parameters is adjusted as a function of the actual working conditions of the compressor or pump (1) that deviate from the nominal working conditions.
