Description
Technical field
The present invention relates to a kind of mixed flow pump or fan for conveying high temperature fluid, belong to the fluid machine of Thermal Energy and Power Engineering
Tool.
Background technology
At present, the pump or blower fan of high temperature fluid are conveyed, what motor and pump or blower fan were integrated, by one long
Rotary shaft is connected, and so radiating for motor is unfavorable, because producing heat after coil electricity, and the rise of thermal accumlation temperature is too high
Temperature to burn coil.Convey high-temperature molten salt pump use vertical suspension type it is in the majority, for example：Jinan China prestige pump industry is limited
The RY type pump for liquid salts of company's production, the impeller for the pump that motor is directly connected to by a major axis, fluid heat can be conducted to electricity
Machine, per ten thousand yuan of number of units.In factories such as chemical plant, pharmaceutical factory, paper mill, power plants, it is necessary to convey high temperature fluid（Liquid or gas
Body）, No leakage.In addition, flow is big, pressure is high pump or blower fan, when conveying high temperature fluid, vapour is easily produced in import
Erosion, influence equipment operation.Centrifugal pump lift is high, and axial-flow pump flow is big, and the two is each has something to recommend him.
The content of the invention
The task of the present invention is to invent a kind of mixed flow pump or fan for conveying high temperature fluid, and it can convey high temperature
Fluid, there is thermal insulation layer between motor and hot fluid, the temperature of motor is not influenceed by fluid, and flow is big, lift is high, net positive suction head
It is small, sealing, do not leak.
The technical solution adopted for the present invention to solve the technical problems is：A kind of mixed-flow pump or wind for conveying high temperature fluid
Machine, includes spiral case, there is centrifugal impeller in spiral case, and volute outlet, the centrifugal impeller are led in the outlet of the centrifugal impeller
Include front shroud or shroud, back shroud or hub disk, wheel hub, the center of the outside wheel hub of cover plate or hub disk, which has, in the rear turns
Axle, one end joint bearing of the rotating shaft, the bearing is arranged on the spiral case inwall, is at the import center of the centrifugal impeller
There is the other end of rotating shaft, the radial direction along the other end of the rotating shaft outwards has axial blade, along the axial blade radius
There is the drum-shaped magnet that bar shaped permanent magnetic steel is regularly arranged into outside direction, or the silicon steel close to axle center is dug up by cage rotor
Piece forms barrel-shaped cage rotor, and the drum-shaped magnet or barrel-shaped cage rotor are the imports of centrifugal impeller, along the drum
The radial direction of shape magnet or barrel-shaped cage rotor outwards has the heat-insulating material of tubbiness, along the half of the heat-insulating material of the tubbiness
Outwards there is stator coil in footpath direction；Another bearing of another termination of the rotating shaft, another bearing is fixed on institute by support
On the inwall for the heat-insulating material for stating tubbiness.The heat-insulating material of the tubbiness is not magnetic conduction, nonconducting heat-insulating material.The permanent magnetism
The NS polar orientations of magnet steel are the radial directions along drum-shaped magnet.There is long spiro nail by stator coil, the heat-insulating material of tubbiness
It is connected and is integrated with spiral case.The operation principle of the present invention is to hollow out the rotor inner core of motor, is axially adding leaf
Wheel, keep its power but can fluid flow into, fluid flow into the direction of the impeller with it is axially consistent, as axial wheel, stream
Body is flowed out after the axial wheel, proceeds immediately to centrifugal impeller, drum-shaped magnet or barrel-shaped cage rotor are centrifugal impellers
Import；Which increases fluid lift.For centrifugal pump, centrifugal impeller includes front shroud, back shroud；For centrifugation
For blower fan, centrifugal impeller includes shroud, hub disk.What is conveyed for Pumps ＆ Fans is all fluid, either pump or blower fan,
Many locality studies methods are identical, and university teaching learns Pumps ＆ Fans in the lump, because the present invention is for pump or blower fan, solve
The scheme of problem is consistent, so proposing in the lump.The heat-insulating material of only tubbiness is not magnetic conduction, nonconducting heat-insulating material,
Can just it make stator field interference-free.
The beneficial effects of the invention are as follows, 1. in structure, has two impellers, is respectively centrifugal impeller and axial wheel,
The import of centrifugal impeller is connected with axial wheel, and centrifugal impeller is easy in the low import of air pressure when conveying high temperature fluid
Cavitation is produced, using the timely fluid replacement of axial wheel, increase inlet pressure, suction inlet lift is increased, eliminates cavitation；2.
On power, the drum-shaped magnet that permanent magnetic steel is regularly arranged into（Or the silicon steel sheet dug up close to axle center forms barrel-shaped mouse cage
Rotor）As rotor, stator and common motor（Direct current, exchange etc.）It is identical, after stator making alive, magnetic field force is produced, is applied
To rotor edge, the magnetic field force suffered by rotor edge is converted into the power that impeller applies to fluid, and shaft strength square mitigates；
3. in thermal insulation sealing, after the heat-insulating material that fluid passes through tubbiness, directly flow out, anticentripetal spiral casing can be wrapped up from centrifugal impeller
Heat-insulating material, axle, bearing are all in fluid, no and external communication, so, the present invention is adiabatic, fluid is not leaked.The present invention
Conveying poisonous high temperature fluid（Liquid or gas）Aspect, different from existing other Pumps ＆ Fans, has oneself only
To processing mode and advantage, in industries such as pharmacy, agricultural chemicals, petrochemical industry, solar energy, power plant, there is the ample scope for abilities of oneself.
