Abstract
The utility model provides an electromagnetic pump which comprises a base. A power driving device, a stator magnetic yoke ring and a conductive fluid channel bracket are installed on the base, wherein an output shaft of the power driving device is connected with a rotor magnetic yoke ring, permanent magnets are respectively installed on the rotor magnetic yoke ring and the stator magnetic yoke ring, a conductive fluid channel is positioned between a movable magnetic yoke ring and a static magnetic yoke ring. Magnetic field lines are enabled to move through rotation of the movable magnetic yoke ring, thereby driving a conductive fluid to flow. The electromagnetic pump provided by the utility model has the advantages of simple structure, easiness in installation, adjustable quantity of flow and flow rate, and the like.
Description
Technical field
The utility model relates to a kind of magnet and the contactless electromagnetic pump of conductor fluid, by the motion driving conductor fluid motion in magnetic field.
Background technology
Up to now, in the prior art, to the conveying of liquid, no matter be transferred liquid and whether can conduct electricity, most mechanical pumps that adopt, such as water pump, blood pump, oil pump etc., they are different according to internal structure, are divided into again piston pump, centrifugal pump etc.Although pump body structure, size varies, and mechanical pump all is that mechanical moving element contacts with being transferred liquid by power-driven system driving device moving component, thus, can cause the friction that is transferred liquid and mechanical moving element unavoidably, corrosion.Cause the pollution that is transferred liquid and the wearing and tearing of mechanical moving element.Moreover, when carrying the fluid such as heavy metal, usually can cause flow inadequate, underpower or suppress the phenomenon of waiting indefinitely and occur.
The defectives such as and existing magnetic drive pump exists loop construction complicated, and cost is higher, or flow is less, and flow is non-adjustable, and can not carry heavy metal, high temperature fluent metal etc.。
Chinese patent literature 202334245U discloses a kind of permanent magnet electromagnetic pump in rotating magnetic field on July 11st, 2012, flow by permanent magnet rotary actuation liquid metal, but it need to use belt, pump housing axle.Bolt connects many, and working space is little, easily friction.Difficulty is installed, the defectives such as debug difficulties.
The utility model content
The utility model is for existing technological deficiency, and a kind of electromagnetic pump is provided, and magnet and conductor fluid are contactless, does not pollute metal, and flow velocity is adjustable, and is simple in structure, easily Installation and Debugging, long service life.
1. technical problem of the present utility model mainly solves by the following technical programs: a kind of electromagnetic pump, comprise pedestal, it is characterized in that: a Power Drive Unit, a conductor fluid channel bracket and a stator magnet yoke ring are installed on the described pedestal, the rotor yoke ring is installed on the described Power Drive Unit output shaft; Have groove on described stator magnet yoke ring and the rotor yoke ring, permanent magnet all is installed in the groove, the permanent magnet in the rotor yoke ring groove is the first magnet group, and the permanent magnet in the stator yoke ring groove is the second magnet group; In the conductor fluid channel bracket conductor fluid passage is installed; Described conductor fluid passage is between stator yoke ring and rotor yoke ring, and the conductor fluid flow direction in the conductor fluid passage is identical with the direction of rotation of rotor yoke ring.Described the first magnet group is extremely all arranged towards the conductor fluid passage according to N, and the second magnet group S extremely all arranges towards the conductor fluid passage, and vice versa.Conductor fluid flows in the conductor fluid passage, does not contact with permanent magnet.
Operation principle of the present utility model: rotate by the first magnet group above the Power Drive Unit rotor driven magnet yoke ring, thereby make the conductor fluid cutting magnetic line and produce electromagnetic force, drive conductor fluid and in the conductor fluid passage, move.
The utility model compared with prior art, have following apparent substantive distinguishing features and advantage: it can solve the deficiencies in the prior art, only needs the rotation by magnet on the rotor yoke ring, produces travelling-magnetic-field, thereby drives flowing of conductor fluid.Conductor fluid only flows in the conductor fluid passage, with other parts joint of electromagnetic pump, can not cause wearing and tearing because of the rotation of rotor yoke ring, pollutes conductor fluid.Other parts of electromagnetic pump also can not be subject to the corrosion of conductor fluid.Therefore the conductor fluid passage easily seals, and Installation and Debugging are easy, and are simple in structure, and flow velocity is adjustable, long service life.
