Abstract

РАБОЧЕЕ КОЛЕСО НАСОСА с промежуточными дисками, раздел ющими проточную часть колеса на каналы, в которых размещены лопасти, имеющие тыльную и рабочую стороны и смещенные в окружном направлении, отличающеес  тем, что, с пелью снижени  виброакустической активности путем уменьшени  неоднородности потока за рабочим колесом, смещение лопастей выполнено так, что тыльна  и рабоча  стороны лопастей соседних и крайних каналов лежат на одной поверхности и  вл ютс  продолжением друг друга.WORKING WHEEL OF THE PUMP with intermediate discs dividing the flow-through part of the wheel into channels in which blades are placed, having rear and working sides and displaced in the circumferential direction, characterized in that with reduction of vibroacoustic activity by reducing the flow non-uniformity behind the impeller, offset The blades are made so that the rear and working sides of the blades of the adjacent and extreme channels lie on one surface and are a continuation of each other.

РАБОЧЕЕ КОЛЕСО НАСОСА с промежуточными дисками, разделяющими проточную часть колеса на каналы, в которых размещены лопасти, имеющие тыльную и рабочую стороны и смещенные в окружном направлении, отличающееся тем, что, с целью снижения виброакустической активности путем уменьшения неоднородности потока за рабочим колесом, смещение лопастей выполнено так, что тыльная и рабочая стороны лопастей соседних и крайних каналов лежат на одной поверхности и являются продолжением друг друга.A PUMP WORKING WHEEL with intermediate disks dividing the flowing part of the wheel into channels, in which there are blades having a rear and working sides and offset in the circumferential direction, characterized in that, in order to reduce vibroacoustic activity by reducing the flow heterogeneity behind the impeller, the blades are shifted made so that the back and working sides of the blades of adjacent and extreme channels lie on the same surface and are a continuation of each other.
