Abstract

The article touches upon the unconfirmed fluid movement in the prism-shaped receiving basin of a multi-unit pumping station, which is fed from a large-volume basin through a fluid pressure overflow pipe. During the joint operation of the units, a constant fluid level is established in the receiving basin when the total output driven by the pumps equals the output of the overflow pipe. When one (or several) units are shut down or initiated, an unconfirmed movement occurs in the overflow pipe and the receiving basin. The pattern of change of the fluid level in the receiving basin over time and the timeframe for the formation of a new level have been determined. This study is of practical significance from the perspective of excluding the discontinuity of fluid flow in the pump suction pipe as well as in terms of avoiding cavitation.
