Submersible full-through-flow gate pump with front guiding vane with adjustable placing angle

Abstract

The invention discloses a submersible full-through-flow gate pump with a front guiding vane with an adjustable placing angle, and relates to the field of water conservancy and water affairs and fluid machinery optimization design. The submersible full-through-flow gate pump with the front guiding vane with the adjustable placing angle sequentially comprises a water inlet horn mouth, a front guiding vane body, a pump shell, a rear guiding vane body and a flap valve from a water flow inlet to a water flow outlet, wherein impeller hubs are arranged in the front guiding vane body, the pump shell and the rear guiding vane body; stators are arranged in the pump shell, and rotors are arranged in the stators; one ends of impellers are welded with inner cavities of the rotors, and the other ends are connected with the impeller hubs; pump shafts are arranged in the impeller hubs, and the inner parts of the impeller hubs are connected with the pump shafts through pump shaft bearings; one end of a rear guiding vane is welded with an inner cavity of the rear guiding vane body, and the other end is connected with the impeller hubs. According to the submersible full-through-flow gate pump with the front guiding vane with the adjustable placing angle, by adjusting the placing angle of the front guiding vane, accurate and intelligent adjustment of the water supply flow of a main canal can be achieved, and then the traditional working mode that the overflowing flow is adjusted by changing the lifting amplitude of a gate along a line is replaced.

Description

technical field [0001] The invention relates to the fields of water conservancy and water affairs and fluid machinery optimization design, more specifically, it is a submersible full-through flow gate pump with adjustable front guide vanes. Background technique [0002] Long-distance main water conveyance canals, especially artificial water conveyance main canals, generally adopt the artesian water supply method. For example, the 1200-km-long main water conveyance main canal of the South-to-North Water Diversion Project uses artesian water supply throughout, and a total of controlling functions are set up on the main canals. There are 64 gates. [0003] Long-distance main water conveyance canals have different water flow requirements in different time periods; under traditional working methods, the overcurrent flow is generally adjusted by changing the lifting range of gates along the line. This method has insufficient joint scheduling accuracy, and if the gates are long It...
