Multistage compressor unit and method for regulating such multistage compressor unit

   
   

The invention relates to a multistage compressor unit which comprises at least two different compressor elements (1 and 2) driven by means of separate electric motors (3, 4) with an adjustable speed, whereby the outlet (8) of a compressor element (1) of one stage connected to the inlet (10) of a successive compressor element (2) of a successive stage, characterized in that the electric motors (2, 4) are identical and therefore have approximately one and the same nominal capacity, whereas between each motor (3, 4) and the compressor element (1, 2) driven thereby, a gear transmission (13, 14) is provided.

La invención se relaciona con una unidad gradual del compresor que abarque por lo menos dos diversos elementos del compresor (1 y 2) conducido por medio de los motores eléctricos separados (3, 4) con una velocidad ajustable, por el que el enchufe (8) de un elemento del compresor (1) de una etapa conectara con la entrada (10) de un elemento sucesivo del compresor (2) de una etapa sucesiva, caracterizada en que los motores eléctricos (2, 4) son idénticos y por lo tanto tienen aproximadamente uno y la misma capacidad nominal, mientras que entre cada motor (3, 4) y el elemento del compresor (1, 2) conducido de tal modo, una transmisión del engranaje (13, 14) es proporcionado.
