Abstract

The invention discloses a pipeline pump with an inlet flow guide structure. The pipeline pump comprises a water inlet runner, an elbow-shaped water inlet elbow, a centrifugal impeller, a volute and a water outlet runner, and induction blades are arranged in the elbow-shaped water inlet elbow; the thickness of the induction blades is 0.02-0.05 time of the inner diameter of an outlet of the water inlet runner; the inlet edge of each induction blade is circular, and an outlet of each induction blade is arc-shaped; and the bending direction of the induction blades is the same as that of the elbow-shaped water inlet elbow. The pipeline pump is simple in structure and convenient to implement, extra external mechanisms do not need to be additionally arranged, the effect of improving the comprehensive performance of the pipeline pump is high, and high popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of fluid pumps, in particular to a pipeline pump with an inlet guide structure. Background technique [0002] Pumps are important general-purpose machinery used in a wide variety of industries. Among them, the inlet and outlet of the pipeline pump are on the same straight line, which has the advantages of small size and convenient installation, so it is widely used in places with limited installation space, such as urban water supply and ship transportation. According to relevant statistics, the energy consumption of pumps accounts for more than 21% of the total annual power generation in the country, so improving the efficiency of pumps is of great significance for energy saving and emission reduction. [0003] Due to the distortion of the inlet flow channel of the pipeline pump, complex flow phenomena such as inlet backflow and flow separation vortex will be induced under the design working conditions, th...
