Abstract
An electromagnetic pump using non-metal liquid as medium is composed of pump body, magnetic poles made of permanent-magnet rare-earth material, electric electrodes, controller, net filter and liquid inlet and outlet. Its advantages are low cost, high efficiency and wide application range.
Description
Technical field
The invention relates to the pump class, or rather, is to be the electromagnetic pump of medium about nonmetal liquid.
Background technique
At present, adopting mechanical pump mostly for the conveying of liquid medium is conveying equipment.Traditional mechanical pump mechanical wear at work is one and do not allow the problem ignored, and will inevitably produce bigger noise environment is polluted, and mechanical efficiency is also not really high.
Adopt the pump housing of special construction to replace mechanical pump under special circumstances, to obtain operational efficiency preferably, electromagnetic pump arises at the historic moment thus.Electromagnetic pump is changed into the notion of tradition " pump " by the mode of mechanical rotation almost do not have the fluid of any mechanical loss straight line motion, and the efficient of pump institute transmission medium is improved greatly.Liquid towards metal electromagnetic pump is set forth in international IEEE electromagnetism bundling the 34th volume the 5th phase p2956-2959 September in 1998 " research that a kind of liquid metal electromagnetic pump is designed a model ".Electromagnetic pump has efficient height, no wearing and tearing, friction, noiseless and control flexible characteristic, is an important breakthrough in electromagnetic application field.
Present electromagnetic pump all is to be medium with the metal liquid, adopts superconductor technology, uses in military affairs and high-tech area, and therefore, application area is little, and cost is high, has limited the extensive use of electromagnetic pump.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of with nonmetal liquid be medium, adopt China to contain abundant rare earth permanent-magnetic material, cost is low, efficient is high and applicable to the electromagnetic pump of multiple occasion.
Nonmetal liquid of the present invention is the electromagnetic pump of medium, comprises the pump housing, magnetic pole, electrode, controller, filter screen, liquid inlet and liquid outlet, it is characterized in that, described magnetic pole is conventional rare earth permanent-magnetic material.
Described magnetic pole is NdFeB material or sodium rice NdFeB material.
Described electrode is a copper polar plate.
The electromagnetic pump usefulness compared to prior art that nonmetal liquid of the present invention is medium is, cost is low, efficient is high and can be used for multiple occasion, and for example extraction of seawater and sewage emissions are specially adapted to the exploitation of the intermediary and later stages oil well in coastal oil field.
Description of drawings

Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
Electromagnetic pump is mainly based on electromagnetic theory, according to the principle of carrying object in the action of a magnetic field lower stress and generation motion, by analytical calculation is carried out in distribution of pump internal magnetic field and the ionization situation of flowing medium under electric field action, and, develop and be applicable to that nonmetal liquid is the electromagnetic pump of medium by simulation analysis and research.
The magnetic pole of electromagnetic pump is selected most important, first-selected neodymium iron boron of the present invention or sodium rice NdFeB material.Earlier with moulding and the permanent-magnet material after burning till magnetize, soak then and mould processing, its objective is the insulating property that increase permanent-magnet material.Magnetic pole 2 after the processing is separately positioned on the upper and lower of the pump housing 1 with the N utmost point and the S utmost point, also can be set to two-layer or multilayer in magnetic field.It is material that electrode 3 adopts copper coin, is separately positioned on left and right two ones of the pump housing 1, is divided into "+" utmost point and "-" utmost point.
The position of the liquid inlet 6 of the pump housing 1 is provided with filter screen 5, and liquid outlet 7 is set to circle usually.
Electromagnetic pump of the present invention is the same with the conventional diving pump in use, and electromagnetic pump is put into the liquid that will carry, connects power supply and gets final product work.According to different transmission mediums and to the requirement of transmission medium different flow, by control voltage is adjusted, thereby finish the control that multiple liquid is carried.
In the practical application, if power is not enough, when promptly needing augmented flow, can adopt the method that strengthens electrode area or increase the magnetic pole logarithm, corresponding controller power also should increase certainly.
Electromagnetic pump of the present invention is to be medium with nonmetal liquid, as long as liquid medium has suitable electric conductivity, liquid will be stressed when energising, so the specific conductance of liquid medium is high more good more.For example, the present invention can be used for the extraction of seawater and sewage emissions, is specially adapted to the exploitation of the intermediary and later stages oil well in coastal oil field, because the intermediary and later stages oil well often needs to adopt the method for injecting seawater to extract oil.
