Abstract
The utility model discloses a high-specific-rotary-speed, efficient and energy-saving single-stage double-suction pump which comprises a pump body, a pump cover, an impeller part, a shaft, a shaft sleeve, a sealing ring and a sealing part. The high-specific-rotary-speed, efficient and energy-saving single-stage double-suction pump is characterized in that the impeller part is composed of a forward mixed-flow impeller and a reverse mixed-flow impeller which are installed back to back, and the reverse mixed-flow impeller and the forward mixed-flow impeller are in mirror symmetry. According to the high-specific-rotary-speed, efficient and energy-saving single-stage double-suction pump, the impellers are mixed-flow impellers, the efficiency of the pump is higher than that of a pump with centrifugal impellers, the specific rotary speed of the pump is high, under the premise that design parameters are definite, the higher pump rotary speed can be selected, therefore, a pump opening is smaller, the manufacturing cost is low, and the manufacturing cost of equipment such as a matching motor is also low.
Description
Technical field
The utility model relates to a kind of water pump, particularly relates to the energy-efficient single-stage double suction pump of a kind of higher specific speed.
Background technique
Single-stage double-suction pump has stable performance because of it, type spectrum is broad, simple in structure, stable, the obvious advantage of grade convenient for installation and maintenance, the supply and drain water system or the cooling circulating water system that are widely used in the industries such as iron and steel, petrochemical industry, thermal power generation, mine, also can be applicable to city tap-water, heating system circulating water and farmland water drainage irrigation and all kinds of hydraulic engineerings etc.
Traditional single stage double suction pump theory is confined to centrifugal pump category always, define its specific speed and be no more than 300, and specific speed to surpass 300 pump be mixed flow pump category, be not suitable for being designed to single-stage double-suction pump.
Adopting the circulation of indirectly cooling thermal power generation is closed system, and single-stage double-suction pump is the selection of such unit circulating water pump the best.Closed system inlet pressure is high, and the cavitation performance of water pump is not major consideration, and water pump can be selected high rotating speed.Select high rotating speed, the specific speed of water pump surpasses 300, and there is no at present suitable hydraulic model.At present, still can only consider to select lower rotating speed, the water pump bore produced is like this large, manufacture cost is high, and the investment of corollary equipment is also high, extremely uneconomical.
For this reason, break through the efficient single-stage double-suction pump of theoretical Limit exploitation higher specific speed, not only can promote single-stage double-suction pump technical development, more can effectively promote the technical development of relevant industries Circulating Pump System.
Summary of the invention
It is high that technical problem to be solved in the utility model is to provide a kind of efficiency, and manufacture cost and operating cost are low, the energy-efficient single-stage double suction pump of stable higher specific speed.
In order to solve the problems of the technologies described above, the energy-efficient single-stage double suction pump of higher specific speed that the utility model provides, its overall structure and working principle and traditional single stage double suction pump are similar, comprise the pump housing, pump cover, wheel member, axle, axle sleeve, seal ring, sealed member, it is characterized in that: described wheel member is comprised of a pair of positive mixed-flow impeller and the back mixing streaming impeller of installing back-to-back, anti-mixed-flow impeller is mirror image symmetry with positive mixed-flow impeller.
The energy-efficient single-stage double suction pump of described higher specific speed, the pump housing and pump cover form the runner of water pump, wherein pumping chamber runner adopts the mixed flow pump pumping chamber model design of mating with positive mixed-flow impeller, and suction chamber runner is half-spiral, adopts the model design of traditional single stage double suction pump.
Adopt the energy-efficient single-stage double suction pump of higher specific speed of technique scheme, compared with prior art tool has the following advantages: impeller is mixed-flow impeller, not only pump efficiency is high compared with receded disk impeller, and specific speed of pump is high, under the certain prerequisite of design parameter, can select higher pump rotary speed, thereby water pump mouth is less, low cost of manufacture, the manufacture cost of the equipment such as auxiliary motor is also low.
In sum, the utility model is that a kind of efficiency is high, can save water pump manufacture cost and operating cost, the energy-efficient single-stage double suction pump of stable higher specific speed.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is traditional single stage double suction pump structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, this practicality invention is described further.
Referring to Fig. 1, the energy-efficient single-stage double suction pump of higher specific speed, comprise the pump housing 2, pump cover 3, wheel member, axle 7, axle sleeve 8, seal ring 6, sealed member 1, its wheel member is comprised of a pair of positive mixed-flow impeller 4 and the anti-mixed-flow impeller 5 of installing back-to-back, positive mixed-flow impeller 4 can directly adopt suitable mixed-flow pump impeller model design, and anti-mixed-flow impeller 5 is positive mixed-flow impeller 4 designed in mirror image; The pump housing 2 and pump cover 3 form the runner of water pump, and wherein pumping chamber runner directly adopts the mixed flow pump pumping chamber model design of mating with positive mixed-flow impeller 4, and suction chamber runner is half-spiral, adopt the design of traditional single stage double suction pump method.
The utility model efficiency is high, easy to maintenance, can reduce water pump manufacture cost and operating cost, stable, has very strong practical and popularizing value.
Personnel in the art should be realized that; above-described embodiment is not with the restriction of the present utility model of opposing; as long as within the scope of connotation of the present utility model, any above-described embodiment technique variation, flexible program are not all exceeded to protection domain of the present utility model.
