Abstract
The utility model discloses a mixed-flow low specific speed compensation type water turbine, which comprises a base, a housing arranged on the base, a variable flow type water inlet pipe connected with one side of the housing, a water outlet pipe arranged at the lower part of the housing, a compensation loop connected with both the water inlet pipe and the water outlet pipe, and a pressure reduction pipe arranged at the upper part of the housing. The mixed-flow type water turbine can be concisely and conveniently positioned in a cooling tower and the manufacturing material is saved. The energy consumption of a water pump is also lowered. The effective water tricking density of the cooling tower under the same water tricking density is increased and the entire resistance of the cooling tower is lowered. Therefore, the problem of the insufficient flow of a conventional mixed-flow low specific speed water turbine at the end of a flow passage is solved.
Description
Technical field
The utility model relates to the compensation water turbine of a kind of mixed flow low-specific-speed.
Background technique
At present, known large-scale concrete construction cooling tower intermediate support all is an entity square concrete post, and a lot of preformed holes or embedded part are arranged at the top; Can only adopt the side water-out manners behind the Francis turbine location like this; This had both increased the inner resistance of cooling tower, had also increased the water resistance that of water turbine simultaneously, and it is a lot of that the tower inner assembly is increased; Reduced effective spray density, the cooling effect of hydrodynamic(al) blower fan machine cooling tower has been brought influence with cooling tower under the spray density.And because the water turbine runner is irregular shape, though the distribution of stator is arranged when fluid gets into runner to end, terminal flow distribution of fluid seldom reduces the whole efficient of water turbine thus.
Summary of the invention
In view of the defective that above-mentioned existing technology exists, the utility model purpose is to propose the compensation water turbine of a kind of mixed flow low-specific-speed in order to overcome present situation.
The technological scheme of the utility model is: the compensation water turbine of a kind of mixed flow low-specific-speed, it comprises: pedestal, be placed in housing, the changeable flow formula intake pipe that links to each other with housing one side on the pedestal, be positioned at the outlet pipe of housing below, the compensation circuit that all links to each other with intake pipe and outlet pipe and be positioned at the relief pipe above the housing.
On the basis of technique scheme, further comprise attached technological scheme:
Said compensation circuit has regulator.
Said housing has transmission shaft and the bearing support that high strength alloy is processed.
Said pedestal supports through the concrete pillar of several hollow-core constructions, and wherein outlet pipe is connected with several water outlet branched pipes, and the water outlet branched pipe then links to each other with the water distribution system of cooling tower.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
Can make the location and installation of Francis turbine in cooling tower succinctly convenient; Save manufactured materials and reduce pump energy consumption; Raising is with effective spray density of cooling tower under the spray density; Reduce the full resistance of cooling tower, changed traditional mixed flow low-specific-speed water turbine in the not enough problem of flow field end fluid flow.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the schematic top plan view of the utility model;
Fig. 2 is the schematic side view of the utility model;
Fig. 3 is the structural representation after the utility model is installed.
Embodiment
Embodiment: shown in Fig. 1-2; The utility model provides the specific embodiment of the compensation water turbine of a kind of mixed flow low-specific-speed, and it comprises pedestal 10, is placed in the housing 12 on the pedestal 10, the spiral intake pipe 20 that links to each other with housing 12 1 sides, the outlet pipe 30 that is positioned at housing 10 belows, the compensation circuit 40 that all links to each other with outlet pipe 30 and intake pipe 20 and the relief pipe 50 that is positioned at housing 10 tops.Its middle shell 12 has transmission shaft 120 and bearing support 122, and this transmission shaft 120 is a high strength alloy, is used to drive blower fan 70 rotations.Compensation circuit 40 has regulator 42, to replenish flow, makes flow field end and top that ability to work equally efficiently arranged, thereby improves the whole efficient of water turbine.Compensation circuit 40 directly links to each other with intake pipe 20, thereby guarantees that the water turbine output power satisfies the power of fan requirement.
Like Fig. 3, during installation, the concrete pillar 80 through several hollow-core constructions comes supporting base 10, and wherein outlet pipe 30 is connected with several water outlet branched pipes 90, and water outlet branched pipe 90 then links to each other with the water distribution system of cooling tower.
During work; Recirculated cooling water gets into erose water turbine runner from intake pipe 20 and takes turns through stator is quiet; Evenly distribution sprays multiform change torsional angle impeller, promotes rotary wheel of water turbine, and the part recirculated cooling water gets into the water turbine flow field end from the regulator 42 of compensation circuit 40 simultaneously; Make water turbine flow field end and top that ability to work equally efficiently arranged, thereby improve the whole efficient of water turbine.
Certainly the foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the people who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection domain of the utility model.
