Abstract
The invention discloses a tail water device of a hydraulic turbine. The tail water device comprises the hydraulic turbine and is characterized by comprising an inlet flange, an inlet tapered tube, an elbow and output expansion tubes, wherein the inlet flange is connected to a volute of the hydraulic turbine; the top end of the inlet tapered tube is connected to the inlet flange; the bottom end of the inlet tapered tube is connected to the elbow; and the two sides of the elbow are provided with the outlet expansion tubes. The tail water device disclosed by the invention is simple in structure, less in occupied space under a necessary working situation and economic for manufacturing and assembling; the structure is rational, so that the tail water can be discharged more smoothly; and the hydraulic turbine efficiency is improved by increasing power vacuum by the expansion tubes.
Description
Technical field
The present invention relates to a kind of water turbine tail water device.
Background technique
Water turbine for cooling tower is in the middle of practical process, and the draft tube of water turbine is very big to the effectiveness affects of water turbine, and present case be generally do not have draft tube or have cylindrical draft tube and conical draft tube wherein it
Use cylindrical draft tube lower, cause device efficiency low, in cooling tower water kinetic energy energy saving technical reconstruction, cause unnecessary failure the efficient of energy recovery;
There is requirement in the space of using conical draft tube that water turbine is installed, adopts conical draft tube under a lot of situation that make, and with bringing huge basic retrofit work, thereby is uneconomicly to have, sometimes or even impossible.
Summary of the invention
According to above deficiency of the prior art, the technical problem that the present invention will solve is: provide a kind of and can overcome above-mentioned defective, energy recovery efficiency is high, and it is little to take up room, water turbine tail water device easy for installation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of water turbine tail water device; Comprise water turbine; It is characterized in that: also comprise suction flange, import canalis spinalis, ell and exit cone, suction flange is connected with the spiral case of water turbine, and the top of import canalis spinalis connects suction flange; The bottom connects ell, and the both sides of ell are provided with exit cone.
Described ell is that two bend pipes that are mutually 90 ° are formed by connecting.
The outlet section of described exit cone is a rectangle.
Described import canalis spinalis is the circular cone diffusing tube.The circular cone diffusing tube provides enough pulls of vacuum for the ell of back.
Suction flange connects the steadiness that guarantees connection; The convenient exit cone that connects of ell that is formed by connecting through the bend pipe that is mutually 90 °; Exit cone has increased power vacuum, has increased pull of vacuum, has so just guaranteed that the tail water device of reduced size can be got to bigger suction; Not only improved energy recovery efficiency, and the little simple installation of whole apparatus structure compact volume.
The beneficial effect that the present invention had is: simple in structure, in the operating mode of necessity, it is little to take up room, and makes, installs economical; Rational in infrastructure, tail water is more unobstructed; Increase power vacuum through diffusing tube, improve turbine efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1, water turbine; 2, suction flange; 3, import canalis spinalis; 4, ell; 5, outlet is expanded
Pipe looses.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are done and to be further described:
As shown in Figure 1; A kind of water turbine tail water device comprises water turbine 1, also comprises suction flange 2, import canalis spinalis 3, ell 4 and exit cone 5; Suction flange 2 is connected with the spiral case of water turbine 1; The top of import canalis spinalis 3 connects suction flange 2, and the bottom connects ell 4, and the both sides of ell 4 are provided with exit cone 5.Ell 4 is that two bend pipes that are mutually 90 ° are formed by connecting.The outlet section of exit cone 5 is a rectangle.Import canalis spinalis 3 is the circular cone diffusing tube.The circular cone diffusing tube provides enough pulls of vacuum for the ell 4 of back.
