Description
Technical field
The utility model relates to a kind of pump, particularly the pump of delivering liquid metal.
Background technique
Pump is the machine that the mechanical energy of prime mover is converted to liquid energy.Pump is used for increasing potential energy, pressure energy, the kinetic energy (high velocity liquid stream) of liquid.Prime mover, increases its energy, thereby makes the liquid that needs quantity the liquid work done by pump shaft impeller rotation, is transported to the eminence of requirement or requires the place of pressure through the flow passage components of pump by the imbibition pond.
Liquid metal pump belongs to low lift, and it is simple in structure, is made up of motor, support, volute, impeller, liquid-discharging tube etc.Impeller is discharged the housing that side has the band volute chamber.The imbibition chamber is positioned at before the impeller, and the hydraulic fluid chamber is positioned at after the impeller, and they and impeller constitute the flow passage components of pump together.Impeller is a pump most important work element, is the heart of flow passage components.Impeller is made up of cover plate and middle blade.
It has often been said or common so-called pump mostly is the industrial water pump greatly, carry liquid mostly to be industrial water or contain the industrial liquid of the quantity of slag.The pump of using in pyrometallurgical smelting of lead technology (being called as plumbous pump sometimes), the liquid of conveying then are the heavy metal liquations of the big proportion of degree high temperature more than 500.The technology that begins to introduce the Imperial smelting process (claim airtight blast-furnace method again, be called for short ISP) of Britain at the seventies is refined plumbous zinc, and through the development in 30 years, its throughput progressively developed into 150,000 tons of plumbous zinc abilities of present annual output from producing 50000 tons of plumbous zinc per year.
ISP smelting technology flow process and plumbous pump position and the effect in technological process: a certain proportion of agglomerate and coke preheating are sent into airtight blast furnace, molten metal bath after melting enters from furnace bottom and melts plumbous pond, by plumbous pump molten metal bath is squeezed into plumbous zinc again and separate cooling bath, after certain hour and means cooling layering, the crude zinc that upper strata proportion is lighter melts liquid and enters the crude zinc moulds in casting wheel and cast zinc ingot metal.The heavier lead of lower floor melts liquid and enters the lead bullion moulds in casting wheel and cast lead pig.The key equipment that plumbous as can be seen pump is airtight shaft smelting from flow process, self throughput size of the raising of throughput and pump has direct related in the flow process.By 3000t/h, progressively transforming 4000t/h and 4800t/h at the plumbous pump capacity of introducing in one's early years, all is to make an issue of to satisfy the technological requirement of expanding production capacity on the wheel speed of pump shaft and power of electric motor.Along with the further expansion of ISP flow process throughput, the bottleneck that the ability of plumbous pump has become the ISP flow process to expand production capacity does not change the size of turbocharger housing structure and impeller size, can't realize and satisfy the raising of plumbous pump capacity.
But the conveying equipment of this high temperature solution of low delivery head great specific gravity fluid delivery pump does not have ripe design method at present, brings very big difficulty for the design of pump.The conveying capacity of pump will improve, and also is not simply the size of existing pump to be amplified simply and can be realized.
The model utility content
In order to improve the conveying capacity of liquid metal pump, the low delivery head great specific gravity fluid delivery pump pump that the utility model provides by changing the dimension scale and the size at the main position of pump, reaches the purpose that improves conveying capacity.
The low delivery head great specific gravity fluid delivery pump that the utility model provides comprises volute, impeller, the liquid-discharging tube that adopts the divergence form helix structure, wherein
1, volute: specific spiral flow channel.
Mouthpiece's starting point: 30 degree
Imbibition chamber diameter: 280～350mm
Runner least radius 21mm
Minimum flow path centre distance: 150mm
Runner maximum radius 70～130mm
Maximum runner centre distance: 247mm
Runner enlarging outlet diameter 265～325mm
2, impeller: be the single blade
Wheel hub CONCENTRIC REDUCER diameter ratio: D is big: D is little=and 1.25:1
Warp and blade height ratio in the wheel hub: among the D: H=2.5:1
The effective imbibition head-room clearance of blade: 60～100mm
Width of blade: 96mm
The mounted angle of blade and the big head plane of wheel hub: 65 degree

The low delivery head great specific gravity fluid delivery pump that the utility model provides belongs to the voluted type mixed flow pump, and it is simple in structure, is made up of volute, impeller, liquid-discharging tube etc., and its volute adopts the divergence form helix structure, and its volute and impeller are the critical components of plumbous pump.
There are imbibition and two kinds of effects of hydraulic fluid in the structure of volute and position by function tool branch.The imbibition chamber is positioned at before the impeller, and the hydraulic fluid chamber is positioned at after the impeller, and they and impeller constitute the flow passage components of pump together.Impeller is a pump most important work element, is the heart of flow passage components.Impeller is made up of cover plate and middle blade.
From the waterpower aspect,, adopt axially symmetric structure and spirality hydraulic fluid chamber more satisfactory for the stability that obtains flowing relatively in the impeller.The arrangement of its hydraulic fluid chamber can allow the liquid that flows out from impeller be collected, and along with the increase of the flow that is collected, the runner radius increases gradually to the exhaust port direction, causes fluid line speed to reduce gradually, thereby has realized the conversion of kinetic energy to pressure energy.Its adaptability is strong, the high efficiency wide ranges.But its runner can not machining, and size shape and surface roughness directly guarantee by casting.Low-lift pump, have greatly that kinetic energy is converted to pressure energy in that hydraulic fluid is indoor,, connect diffusing tube behind the helix of hydraulic fluid chamber in order to realize the conversion of kinetic energy fully, and making that the flow direction and the volute chamber radius of the outlet of hydraulic fluid chamber are perpendicular, this structure has guaranteed to eliminate the rotational component that flows.
The low delivery head great specific gravity fluid delivery pump that the technological scheme that provides according to the utility model designs can reach 5100 tons/hour conveying capacity, has realized the big output quantity of hyperbaric solution body, can satisfy the requirement that improves the technology production capacity.
