Abstract

The invention relates to a double-suction centrifugal pump impeller and a vortex chamber guide device. The invention comprises centrifugal pump volute, blade, impeller guide plate, vortex chamber guide plate, front cover plate, rear cover plate and impeller rotating shaft. The front cover and the rear cover of the impeller are fixed with an impeller deflector between the working surface of the adjacent blade and the back of the blade to guide the liquid flow just entering the impeller. The impeller deflector is welded on the front cover and the rear cover Between, the angle between the tail of the deflector and the outer diameter of the impeller is equal to the blade outlet angle. On the inner wall of the volute of the centrifugal pump, there are vortex deflectors distributed at unequal angles along the Archimedes spiral. The combination guide device of the impeller and the volute proposed by the invention can greatly improve the operating efficiency of the pump.

Description

technical field [0001] The invention belongs to the technical field of fluid machinery and relates to a method for improving the performance of the centrifugal pump by adding an impeller and a vortex deflector device to the double-suction centrifugal pump. Background technique [0002] The water pump is a general mechanical product with a large quantity and a wide range. Double-suction centrifugal pumps are one of the most numerous and widely used pump products. It is widely used in various fields of national economic construction due to its large single-machine flow rate and convenient use and maintenance. But at present, domestic research on double-suction pumps is not thorough enough, and the average technical level of efficiency indicators of domestically produced double-suction pumps is 2.5% lower than that of foreign countries. Carrying out basic research on the internal flow mechanism of double-suction pumps and improving the operating efficiency of double-suction p...
