Abstract
The utility model discloses a mixed flow low specific speed compensating water turbine which comprises a base, a shell placed on the base, a variable flow water inlet pipe connected with one side of the shell, a water outlet pipe arranged below the shell, a compensation loop connected with the water outlet pipe, a pressure reduction pipe positioned above the shell, and a pump positioned in the compensation loop. In the turbine, the mixed flow water turbine can be positioned and installed simply and conveniently in a cooling tower, a manufacturing material is saved, the energy consumption of a water pump is reduced, effective water drenching density of the cooling tower under the same water drenching density is improved, the absolute damping of the cooling tower is reduced, and the problem that the traditional mixed flow low specific speed water turbine has insufficient fluid low at the tail end of a runner 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, 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 resistance of cooling tower inside, 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 enters runner to end, terminal flow distribution of fluid seldom reduces the efficient of water turbine integral body thus.
Summary of the invention
In view of the defective that above-mentioned prior art 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 technical solution 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 arranged in the housing below outlet pipe, the compensation circuit that links to each other with outlet pipe, be positioned at relief pipe above the housing and the pump that is positioned at compensation circuit.
On the basis of technique scheme, further comprise attached technological scheme:
Described pump is supercharging or increment pump.
Described compensation circuit or directly link to each other with intake pipe, or link to each other with the cooling tower catch basin.
Described compensation circuit has regulator.
Because the utilization of technique scheme, the utility model compared with prior art has following 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 the problem of traditional mixed flow low-specific-speed water turbine in flow field end fluid flow deficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a schematic top plan view of the present utility model;
Fig. 2 is a schematic side view of the present utility model.
Fig. 3 is the structural representation after the utility model is installed.
Embodiment
Embodiment: shown in figure 1-3, 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 changeable flow formula intake pipe 20 that links to each other with housing 12 1 sides, the outlet pipe 30 that is arranged in housing 10 belows, the compensation circuit 40 that links to each other with outlet pipe 30, the pump 60 that is positioned at the relief pipe 50 of housing 10 tops and is positioned at compensation circuit 40.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 be arranged, thereby improves the efficient of water turbine integral body.This compensation circuit 40 can directly link to each other with intake pipe 20, also can link to each other with the cooling tower catch basin separately, thereby guarantee that the water turbine output power satisfies the power of fan requirement.Pump 60 is supercharging or increment pump, when being particluarly suitable for flow system flow or lift and being lower than the required rating number of water turbine, satisfies the power of fan requirement to guarantee the water turbine output power.
As Fig. 3, during installation, the concrete pillar 80 by several hollow-core constructions comes supporting base 10, and wherein outlet pipe 30 is connected with several water outlet branched pipes 90, and links to each other with the water distribution system of cooling tower by water outlet branched pipe 90.
During work, recirculated cooling water enters erose water turbine runner from intake pipe 20 and takes turns through stator is quiet, evenly distribute and spray multiform change torsional angle impeller, promote rotary wheel of water turbine, the part recirculated cooling water enters 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 be arranged, thereby improve the efficient of water turbine integral body.
Certainly the foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present 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 present utility model.
