METHOD OF AUTOMATIC CONTROL OVER BLOWER IMPELLER RPM

摘要

FIELD: engines and pumps.SUBSTANCE: blower impeller rpm is controlled in controlled set of blowers integrated by single interface line. Note here that impeller rpm adjustment and variation in quantity of active driven blowers are executed by assigning drive blow control functions to controlled group. For this, frequency-controlled drive and data processing and automatic control unit are built in every blower of formed controlled group. Interface line is used along with assigned drive blower to control rpm of impellers and to vary quantity of active controlled blowers. Besides, activity marker is introduced in control algorithm to switch one of driven blower in the drive lower mode when said marker disappears.EFFECT: higher reliability and efficiency.1 cl, 1 dwg
