BATCH CHANGE CONTROL FOR VARIABLE SPEED DRIVEN CENTRIFUGAL PUMPS AND PUMP SYSTEMS

摘要

A pump system includes an interface detection meter (380) arranged at a pipeline assembly (350), a drive assembly (322, 324) for controlling speed of a pump (302, 304, 306, 308) arranged at the pipeline assembly (350), a discharge pressure control assembly and/or flow control assembly for controlling discharge pressure of the pump system, and a control assembly (382, 384, 386, 388, 390, 392, 396) operably coupled to the drive assembly (322, 324) and/or the discharge pressure control assembly and/or the flow control assembly. A logic control (382) of the control assembly (382, 384, 386, 388, 390, 392, 396) receives fluid data provided by the interface detection meter (380), and forwards the fluid data for calculating speed set points for the drive assembly (322, 324) and/or discharge pressure control parameter and/or set points for the discharge pressure control assembly, and/or flow rate control set points for the flow control assembly.
