Description
Technical field
This utility model relates to a kind of electromagnetic pump, particularly to a kind of lightweight iron core electromagnetic pump.
Background technology
Electromagnetic pump is to utilize the interaction of electric current in magnetic field and conductor fluid, makes fluid be produced pressure by electromagnetic force
Power gradient, thus promote the device that fluid moves.Owing in actual applications, electromagnetic pump is mostly used for pump liquid-state metal, institute
So that generally it is claimed liquid metal electromagnetic pump again.
Electromagnetic pump does not has mechanical moving element, has simple in construction, good airproof performance, and high temperature resistance is good, and operating is reliable, no
Need the advantages such as sealing, be mainly used in the liquid such as the active sodium of chemical property, potassium, sodium-potassium-sodium alloy and toxic heavy metal lead, hydrargyrum
The pumping of metal, it is also possible to the pumping of melted non-ferrous metal in Foundry Production.
In conventional electromagnetic pump, its pump ditch components is provided with iron core, for obtaining preferable design parameter, and usually can be right
The overall dimensions of iron core proposes certain requirement.But, owing to the density of core material is bigger so that the weight of electromagnetic pump is excessively
Heavy, cause its transport, install and the operation such as maintenance is the most inconvenient, the most also the supporting condition in application is proposed higher wanting
Ask, constitute all disadvantageous application and limit.
Utility model content
Problem that is the heaviest due to iron core for the existing electromagnetic pump of solution, that have impact on its application portability, this utility model
Provide a kind of lightweight iron core electromagnetic pump.
This lightweight iron core electromagnetic pump includes solenoid, stator pack and pump ditch assembly, described solenoid and stator pack position
Outside in pump ditch assembly；Described stator pack uses E shaped iron core；Described pump ditch assembly includes outer tube and iron core；Described outer tube two
End internal diameter is gradually reduced, and forms two cone structures, and the top of each cone structure is equipped with liquid metal pipe joint, outside outer tube
Wall surface lays one layer of heat-barrier material；Described iron core is positioned at outer tube central authorities, and iron core two ends external diameter is gradually reduced, and forms two cones
Shape structure；Forming ring cavity between described outer tube and iron core, constitute liquid metal runner, described iron core passes through some fixtures
Fix with outer tube and be connected；Described iron core fills graphite in using hollow design, its cavity.
Described heat-barrier material uses soft felt nanometer heat insulation material to be preferred.For the outer tube outer wall of 500 DEG C, 5mm is thick
Soft felt nanometer heat insulation material can obtain the temperature difference of about 355-360 DEG C.
Described stator pack is become preferred by multilamellar silicon steel plate stacking, to reduce eddy current, reduces iron loss, reduces stator pack and sends out
Heat.
Described solenoid is many groups, and it is preferred for being provided with mica sheet between each adjacent electromagnetic coil.
It is preferred for being additionally provided with pivot flange outside described stator pack.
It is preferred for being additionally provided with patch panel outside described stator pack.
Described stator pack two ends can also arrange support.
In lightweight iron core electromagnetic pump development process of the present utility model, the problem the heaviest for solving iron core, first
Expect using hollow design.But test shows, hollow core can bring many unfavorable factors, the serious reality restricting electromagnetic pump
Application.Owing to being usually used in pump liquid-state metal, therefore electromagnetic pump core is very big in the temperature difference of work and off working state, hollow ferrum
Expanding with heat and contract with cold of core inner gas can bring obvious stress to iron core, to itself also by expanding with heat and contract with cold the iron core having a strong impact on
Constitute and threaten greatly, easily cause the deformed damaged of hollow core.If using the measure thickening hollow core outer wall to keep away
Exempt from stress damage, then the problem that iron core is the heaviest cannot preferably be solved.
To this end, the utility model proposes a kind of by internal for the hollow core technical scheme filling graphite, replace with graphite
Gas within hollow core, it is to avoid gas expands with heat and contract with cold the stress damage causing it.Owing to graphite is solid, have
Good conductivity, high-temperature stability and suitable thermal coefficient of expansion, can provide for hollow core under this fill pattern
Good stress support, the extruding desirably preventing liquid metal flows generation causes hollow core to deform so that hollow core
Possesses preferably service life.
In sum, lightweight iron core electromagnetic pump of the present utility model have employed the internal hollow core filling graphite, full
On the premise of foot service life and reliability, it is achieved that the lightweight of electromagnetic pump so that the transport of electromagnetic pump, install and maintenance etc.
The convenience of operation is significantly improved, and extends the range of application of electromagnetic pump, achieves good effect.
