On the operation of blowers controlled by mechanical blades
under extreme conditions

Summary

Reducing energy costs for air supply to aeration systems of the treatment facilities by using adjustable air blowers is an urgent task. A comprehensive analysis of operating single-stage centrifugal air blowers controlled by mechanical rotating blades under low ambient temperatures typical for Russia is presented. In the process of monitoring, the parameters of the air blowers were monitored (air temperature at the compressor inlet, excess pressure at the compressor outlet, vibration level, lubricating oil temperature, temperature of the impeller shaft bearings, input current consumed of the electric drive motor).
