Description

A kind of pollution discharge pump for water power plant blowdown
Technical field
The utility model relates to field, water power plant, particularly relates to a kind of pollution discharge pump for water power plant blowdown.
Background technique
Water power plant is the integration engineering facility that water can be converted to electric energy, generally comprises the reservoir and Diversion system of hydropower station, power plant building, electromechanical equipment etc. that are formed by dash, outlet structure escape works.The high water level water of reservoir flows into factory building promotion turbine-generator units through diversion system and sends electric energy, then through boosting transformer, switchyard and electric transmission line input electrical network.In many rivers, due to the destruction of upstream, river basins vegetation, and in ascendant trend year by year, unit flow passage components wearing and tearing aggravation, rotating wheel upper leak-proof ring gap expands rapidly, and top cover upper cavity pressure significantly rises, and causes water seal wearing and tearing and water leakage significantly to increase.Flood tide water brings the impurity such as a large amount of quartz sands and emery, and these silts deposit rapidly in sump on the one hand, and blocking draining pump intake, has a strong impact on the normal operation of water pump.On the other hand, silt is evacuated to downstream tail water by draining pump, when water pump vane, bearing and sealing etc. lose, due to quartz sand and emery extreme hardness, causes water pump operation to occur the problems such as seal failure, pump shaft is levigate in a short time.In order to desilting, need that pollution discharge pump is installed and carry out blowdown, but pollution discharge pump is in the prior art suitable for less foreign material when carrying out blowdown work, and the foreign material in sewage will easily result in blockage in pollution discharge pump, thus the serious life-span affecting pollution discharge pump and filth-discharging effect.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of pollution discharge pump for water power plant blowdown.
The utility model is achieved through the following technical solutions:
A kind of pollution discharge pump for water power plant blowdown, comprise the blowdown pump housing, inlet tube, outer pipe, pumping chamber and impeller, the rear of pumping chamber is provided with impeller cavity, impeller is positioned at impeller cavity, described impeller is arranged in rotating shaft, the front end of described impeller is connected with fixing rod, and fixing rod rotates together along with rotating shaft, and described fixing rod is provided with slitting wheel.
As optimal technical scheme of the present utility model, the cross section of described slitting wheel is triangular in shape, adopts nickel-chromium material to make.
As optimal technical scheme of the present utility model, described cutting blade offers circular hole.
Compared with prior art, the beneficial effects of the utility model are: the utility model by being provided with slitting wheel in pollution discharge pump, there is enough intensity, foreign material can be cut off, disrumpent feelings or smash, prevent foreign material to the infringement of impeller, improve the working efficiency of pollution discharge pump, extend the working life of pollution discharge pump, and long service life, unload with easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: the 1-blowdown pump housing; 2-inlet tube; 3-outer pipe; 4-pumping chamber; 5-impeller; 6-impeller cavity; 7-rotating shaft; 8-fixing rod; 9-slitting wheel; 10-circular hole.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of pollution discharge pump for water power plant blowdown, comprise the blowdown pump housing 1, inlet tube 2, outer pipe 3, pumping chamber 4 and impeller 5, the rear of pumping chamber 4 is provided with impeller cavity 6, impeller 5 is positioned at impeller cavity 6, described impeller 5 is arranged in rotating shaft 7, and pumping chamber 4 is provided with impeller cavity 6 relative to the side of inlet tube 2, and impeller 5 is arranged in impeller cavity 6 completely, be held back in by impeller 5 in impeller cavity 6, the impeller 5 thus in the present embodiment reduces with the touch opportunity of dirty impurities in water.
The front end of described impeller 5 is connected with fixing rod 8, and fixing rod 8 rotates together along with rotating shaft 7, and described fixing rod 8 is provided with slitting wheel 9, and described slitting wheel 9 offer circular hole 10.By being provided with slitting wheel in pollution discharge pump, there is enough intensity, foreign material can be cut off, disrumpent feelings or smash, prevent foreign material to the infringement of impeller, improve the working efficiency of pollution discharge pump, extend the working life of pollution discharge pump, and long service life, unload with easy to maintenance.
Preferably, the cross section of described slitting wheel 9 is triangular in shape, adopts nickel-chromium material to make.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
