A fluid mechanical rotating impeller

Abstract

The invention discloses a fluid machinery rotating impeller, and belongs to the technical field of impellers. The fluid machinery rotating impeller comprises a front cover plate and a back cover plate; a peripheral groove is peripherally formed in the front cover plate; multiple separation plates and multiple rotating ball ejectors are uniformly arranged in the peripheral groove in the peripheraldirection; the separation plates and the rotating ball ejectors are arranged at intervals; multiple front blades are uniformly arranged on the inner side of the front cover plate in the peripheral direction; multiple back blades are uniformly arranged on the inner side of the back cover plate in the peripheral direction; the front blades and the back blades are arranged in a staggered mode; a baffle plate is arranged between the front blades and the back blades; and the sides, far from the front cover plate, of the front blades and the sides, far from the back cover plate, of the back blades are connected with the baffle plate. The fluid machinery rotating impeller is simple in structure, and improves the tightness and the practicability under the condition of not increasing internal friction force of the impeller and fluid machinery; and through the upper and lower blades arranged in the staggered mode, the time of feeding fluids in an outlet is shortened, and the fluid stability andthe fluid pumping quantity are improved.

Description

technical field [0001] The invention relates to the technical field of impellers, in particular to a fluid mechanical rotating impeller. Background technique [0002] Fluid machinery is widely used in daily life and industrial production, and the impeller of fluid machinery is an important working part of fluid machinery. Its shape, size, and processing technology have a decisive impact on the performance of fluid machinery. The existing fluid machinery rotating impeller The sealing performance between the front and rear cover plates and the internal cavity of the fluid machine is not good, and the fluid inside the impeller is easy to leak. Contents of the invention [0003] In order to solve the technical problems existing in the prior art, such as the poor sealing performance between the front and rear cover plates of the rotating impeller of the fluid machine and the internal cavity of the fluid machine, and the easy leakage of the fluid inside the impeller, the present...

Problems solved by technology

[0003] In order to solve the technical problems existing in the prior art, such as the poor sealing performance between the front and rear cover plates of the rotating impeller of the fluid machine and the inner cavity of the fluid machine, and the easy leakage of the fluid inside the impeller, the present invention provides a rotating impeller of a fluid machine with a simple structure , Without increasing the internal friction between the impeller and the fluid machine, the sealing performance of the impeller is increased, and the practicability is strong. The impeller uses the staggered upper and lower blades to reduce the time for the fluid to enter the outlet, and increase the stability and pumping of the fluid. amount of fluid
