Problems solved by technology

This design method is based on experience-based single-working-condition design method, and there are too many empirical factors, and there is no scientific theory and mathematical model as support, which makes the determination of the blade outlet placement angle somewhat accidental, and cannot guarantee that the designed impeller has better hydraulic performance

Abstract

The invention provides a centrifugal pump impeller achieving adjustment of the blade outlet angle. The centrifugal pump impeller comprises blades, a rear cover plate and a rear cover plate outer race, and the rear cover plate outer race and a rear cover plate outer ring are positioned and installed through an annular guide rail; one end of each blade is mounted on the rear cover plate, and the other end of each blade is mounted on the rear cover plate outer race; and a rotatable gear is installed in the rear cover plate and meshed with the rear cover plate outer race, the rear cover plate outer race rotates along the rear cover plate outer ring by rotating the gear, and therefore the blades deform and are used for changing the blade outlet angle. By means of the centrifugal pump impeller, the angles of the blades are adjusted through the gear structure, and the purpose of achieving the optimal working efficiency under different working conditions is achieved.

Description

Technical field [0001] The present invention relates to the field of pump technology, and more particularly to a centrifugal pump impeller that adjusts the outlet angle of the blade. Background technique [0002] As a general purpose machine, the pump is mainly used to convert the mechanical energy of the original motivation into fluid, which has a wide range of high-tech fields such as the national economy and aerospace ships. According to statistics, the power consumption of the pump accounts for 18% of total power generation. Therefore, there is an important impact on the research and design level of centrifugal pumps, which has an important impact on national economic development, energy conservation and environmental protection. [0003] Due to its large traffic, the centrifugal pump is extremely important in flood control, industrial and agricultural water supply, cross-river water distribution and other projects, but due to the seasons and environmental water relying on se...
