DAMPING PRESSURE OUTPUT CENTRIFUGAL PUMP
The article deals with the problem of damping of pressure fluctuations at the output of the machine and the blade, in particular, the centrifugal pump by installing a discharge pipe devices that provide resistance to flow of hydraulic working fluid. Under certain conditions, these fluctuations can generate resonance phenomena in a system of pipelines and execution units, reducing the reliability of their operation. The possibility of damping of turbulence by means of the front, located across the river flow. Front turbulators were made of perforated metal plates and grids. The results showed that the best damping properties of the turbulators have a front mesh. With increasing Reynolds number turbulence promoters wheel, made of perforated plates, showing no damping, and generating properties, leading to an increase in the amplitude of pressure fluctuations.
