The invention discloses a dual-inflow four-impact water turbine streaming silencing device which comprises a base. A machine body is fixedly mounted on the base. A water inlet pipe and a water outletpipe are mounted at the output end and the input end of the machine body correspondingly. A sound insulation cover is arranged on the base, the machine body is arranged in the sound insulation cover,and suction cups are fixedly connected to the bottom of the sound insulation cover. The adsorption ends of the suction cups are adsorbed to the upper surface of the base. Through holes are symmetrically formed at the two corresponding ends of the sound insulation cover, and the water inlet pipe and the water outlet pipe penetrate the corresponding through holes correspondingly and extend towards the outer portion of the sound insulation cover. A cavity is arranged in the sound insulation cover and filled with cooling water. Multiple copper bars are evenly connected to the inner side wall of the sound insulation cover in a matrix shape at equal distances. The end, away from the machine body, of each copper bar penetrates the inner side wall of the sound insulation cover and extends into thecooling water. Cooling fins are evenly connected to the upper end of the sound insulation cover in a matrix manner at equal distances. The device is simple in structure and convenient to operate, a water turbine is subjected to silencing and noise reduction, and meanwhile the water turbine is subjected to omni-directional cooling improvement.
Description
technical field [0001] The invention relates to the technical field of hydraulic turbine auxiliary equipment, in particular to a double-inlet and four-impact hydraulic turbine circumvention muting device. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy, and it belongs to the turbomachinery in fluid machinery. As early as around 100 BC, the prototype of the water turbine appeared in China - the water wheel, which was used to lift irrigation and drive grain processing equipment. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, the water in the upstream reservoir is led to the turbine through the diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. The water that has done work is discharged downstream through the tail water pipe. The higher the wate...
