Description
Technical field
The present invention relates to a kind of axial-flow pump for conveying high temperature fluid, belong to Thermal Energy and Power Engineering machinery.
Background technology
High temperature fluid pump purposes is a lot, for example：Chemical plant, paper mill, power plant, pharmaceutical factory, oil plant, high temperature are too
Heat circulating system that sun can be utilized etc..What existing axial-flow pump impeller was connected together with line shaft, high temperature in the transmission
When fluid, prime mover can be passed to along line shaft, cause the temperature rise of prime mover, also, the equipment of conveying senior middle school temperature needs
Outer layer adds Insulation, to prevent heat losses.When Insulation is implemented to pump, if prime mover is not wrapped in
Inside heat-insulation layer, if heat can be lost a part of by prime mover and prime mover is made in into insulation the inside one piece, so for
The normal work of prime mover is affected, because prime mover needs what is cooled, for example, the rotor of bigger motor just has
One fan, prevents thermal accumlation, temperature from raising and burning out motor.Axial-flow pump is also easy to produce leakage, and such pump is for passing
The virose fluid of the fluid of defeated high temperature, particularly high temperature, brings unfavorable factor.
The content of the invention
In order that the insulation of the normal work and high temperature of prime mover, for the leakage in being transmitted without high temperature fluid,
The present invention provides a kind of axial-flow pump for conveying high temperature fluid, is adiabatic between the pump and prime mover, does not leak.
The technical solution adopted for the present invention to solve the technical problems is：A kind of axial-flow pump for conveying high temperature fluid, bag
Impeller, wheel hub, rotary shaft, fore bearing, rear bearing, stator and pump case are included, the impeller is fixed on wheel hub, the wheel hub two ends
There is rotary shaft, the rotary shaft two ends are arranged on fore bearing and rear bearing, the two ends of the fore bearing and rear bearing pass through branch
Frame is fixed in support ring, and the support ring is fixed on pump case, and a tubular is fixed with the outer peripheral circumference of the impeller
Rotor, the cylindrical rotor be it is several to magnetic pole constitute motors permanent magnet rotor structure, or hollowed out middle silicon steel sheet and
Maintain the cage rotor structure of the motor of edge silicon steel sheet；The pump case is adiabatic and non-conductive, non-magnetic drum
Pump case is surrounded on the outside of rigid body, the pump case a motor stator with winding.Non-conductive, the non-magnetic circle of the pump case
The material of barrel shape rigid body is glass, ceramics, safety glass, toughened ceramic, macromolecule polymer material, and the drum is firm
The thermal insulation of body pump case is by coating insulation material on the drum rigid body pump case or by the drum rigid body
Pump case is fabricated to closed bilayer, double-layer inner and is coated with reflective membrane to realize for vacuum, double-layer inner.The motor stator
Winding can be three AC Electrical Machine Windings, individual event AC Electrical Machine Winding, direct current generator winding, stepper motor winding and direct current without
Brush electric car winding.The present invention operation principle be：An adiabatic cylinder shape rigid body will be added between motor rotor and stator,
The outward flange of rotor is retained into motor rotor property, impeller shape is made into the inside of rotor, impeller and edge rotor are one
Body, stator field causes rotor to rotate, impeller driving flow of fluid.The mode of heat transfer has conduction, convection current and radiation,
By will coat insulation material on drum rigid body pump case, or the drum rigid body pump case is fabricated to closed double
Layer, double-layer inner are vacuum, double-layer inner is coated with reflective membrane, to realize the thermal insulation of pump case, so as to realize that the heat of fluid is passed
Pass less than stator so that stator operating temperature is not influenceed by fluid temperature (F.T.), working stability.Because two bearings of design are all in stream
Internal portion, so fluid will not be leaked.
The beneficial effects of the invention are as follows, it is adiabatic between pump and motor, when conveying senior middle school's temperature fluid, the heat of fluid
Amount is not distributed on pump, and electromotor winding temperature is not influenceed by fluid temperature (F.T.), working stability, and fluid will not be leaked.Due to
Axial-flow pump have flow it is big/lift it is low the characteristics of, structure of the invention is easy to that multiple products are connected to improve lift.
The large-scale present invention pump case can be made it is ceramic glass fiber reinforced, the support of base is corresponding with position of bearings.The present invention is in
Application potential in high temperature fluid transmission is very big.
