Abstract

The invention relates to a water jetting air pumping device. The water jetting air pumping device comprises an upper connecting pipe, an upper absorption chamber, a middle throat pipe and a lower diffusion chamber which are coaxially arranged up and down and communicated with one another; the upper and lower ends of the upper connecting pipe are provided with an upper flange A and a lower flange A, and the upper end of the upper connecting pipe is provided with a water inlet; the upper absorption chamber comprises an outer cylinder body and an annular-shaped shunting sieve, wherein the annular-shaped shunting sieve coaxially sleeves the interior of the outer cylinder body, and the side wall of the outer cylinder body is provided with an air inlet; a plurality of shunting small holes are evenly distributed on the side wall of the annular-shaped shunting sieve, and a pair of shunting big holes which are arranged symmetrically are formed in the side wall of the annular-shaped shunting sieve. The water jetting air pumping device has the advantages that the structure of the water jetting air pumping device is simple, compared with the traditional water jetting air pumping device, the water jetting air pumping device is characterized in that a shunting type absorption camber structure is adopted, a shunting sieve is arranged in the upper absorption chamber, when the air is pumped, the air is evenly absorbed after shunting, the pumping efficiency is improved, and the air pumping is more stable.

Description

technical field [0001] The invention relates to a water jet pumping device, in particular to a high-efficiency water jet pumping device. Background technique [0002] The water jet extractor is a special equipment for turbogenerator set to suck non-condensable gas and maintain the vacuum of the condenser. With the water pressure of Mpa, the water flows through the nozzle of the air extractor to form a high-speed water column, and the gas runs under the water mass point, so that the condenser in the generator set maintains a relatively vacuum. [0003] In the utility model patent with the patent number CN 104196769 A, an environment-friendly multi-channel jet water extractor is mentioned, which includes two working nozzles, and the two working nozzles are installed at one end of the working room, and the tails of the two working nozzles are facing each other. Connect the working medium inlet of the studio, the water medium enters the working nozzle from the working medium in...
