Abstract

The invention provides a constant pressure type tail pipe of a hydropower station, and belongs to the field of hydraulic power generation equipment. The constant pressure type tail pipe comprises a lower tapered pipe, a current stabilization pipe and an upper tapered pipe, wherein the structure of the upper tapered pipe is the same as that of the lower tapered pipe; the diameter of the lower end face of the upper tapered pipe is larger than the diameter of the upper end of the upper tapered pipe; a plurality of current guiding ribs are arranged in the upper tapered pipe; clamping grooves are formed in the current stabilization pipe; and the clamping grooves and the current guiding ribs are correspondingly arranged and are in interference fit. According to the constant pressure type tail pipe, strength is high, a current is divided, and internal pressure is maintained stable.

Description

technical field [0001] The invention belongs to the field of hydroelectric power generation equipment, and relates to a tailpipe of a constant-pressure hydropower station. Background technique [0002] There are many kinds of hydropower parts, and the application environments of hydropower parts are relatively diverse. They need to be immersed in water for a long time, and the anti-corrosion performance of the parts is particularly high. One of the important parts of draft tube hydropower generation, the draft tube is used as a discharge device. It is under high pressure for a long time to ensure the smooth discharge of the internal water flow. Especially when the terrain is relatively complex, the laid draft tube is longer, bears a lot of pressure, and bears pressure for a long time. In order to ensure the normal operation of the draft tube, it is necessary to ensure that the draft tube has Higher length improves the service life. At present, the common improvement of draft...
