Abstract
The utility model relates to a moving-coil electromagnetic diaphragm pump, comprising a pump body, a sucking valve, a discharge valve, a diaphragm, a permanent magnet, windings, etc. The utility model is characterized in that a winding frame around which windings are coiled is fixedly conjoined with the diaphragm; the permanent magnet is fixed on the pump body, a columnar magnetic conductor is arranged in the through hole of the permanent magnet, and the magnetic conductor is partially embedded in the inner hole of the winding frame and forms an annular space with the through hole of the permanent magnet; when windings are powered on, the winding frame which is connected with the diaphragm makes reciprocating straight-line motion with the columnar magnetic conductor as the guide way, under the action of the magnetic field. The utility model can realize large power output under certain electric and magnetic parameters and is easy to realize the miniaturization of electromagnetic diaphragm pumps.
Description
The utility model belongs to the improvement design of electromagnetic diaphragmpump.
It is the mode of structure of moving body for the fixed body permanent magnet that existing electromagnetic diaphragmpump all adopts hot-wire coil to produce the alternating magnetic field part.Its power output form of this structure should not make straight line motion.And because of bigger as movement parts weight with permanent magnet, itself inertia is big, power consumption is also bigger, is difficult to realize more high-power output.
The purpose of the utility model provides less, the simple in structure moving coil electromagnetic diaphragmpump of a kind of power consumption, makes it deciding can to realize more high-power output under the electromagnetic parameter situation, easily realizes the microminiaturization of diaphragm pump again.
The technological scheme that realizes above-mentioned purpose is: this moving coil electromagnetic diaphragmpump, form by the pump housing, inspiration valve, expulsion valve, barrier film, permanent magnet, coil etc., and it is characterized in that the coil carrier that is wound with coil places diaphragms and fixed with it being connected as a single entity; Permanent magnet with through hole places barrier film and coil top and is fixed on the pump housing by magnet holder, is fixed with a cylindricality magnet case in its through hole, and this magnet case is partially submerged in the endoporus of coil carrier and with the permanent magnet through hole and is formed with annular gap; Making the coil carrier that connects barrier film behind the coil electricity under the action of a magnetic field is that guide way does reciprocating linear motion in annular gap with the cylindricality magnet case.
Press the diaphragm pump that such scheme is made, because of greater weight permanent magnet and magnet case are fixed on the pump housing, and be connected on the barrier film as movement parts with coil and coil carrier, because of its weight is lighter, oneself power consumption is less, has improved effect, and is easy to make micropump.Compare under identical electricity, magnetic parameter situation with the pump of known technology, can realize more high-power output, and simple in structure.
Accompanying drawing 1 is the structural representation of this moving coil electromagnetic diaphragmpump.
The embodiment who provides below in conjunction with accompanying drawing further describes.As shown in the figure, the diaphragm pump of present embodiment part is mainly by the pump housing (1), inspiration valve (a), and expulsion valve (b), pipe joint (2), barrier film (3) is formed.Wherein inspiration valve (a) and expulsion valve (b) constitute by back-up ring (4), valve bush (5), glue valve (6) and fastenings bolt (7), packing ring (8), nut (9), and difference only is that two valves are installed on the glue valve (6) that makes two valves after the pump housing (1) is gone up is open and close in the same way.So this part is because of belonging to known category not superfluous stating.As described in Figure, present embodiment realizes that the power setting part of barrier film (3) action is by permanent magnet (10), and magnet holder (11), cylindricality magnet case (12), back-up ring (13), rubber cushion (14), coil (15), coil carrier (16), pad (17), nut (18), nut (19), nut (20), nut component such as (21) are formed.The coil carrier of making of engineering plastics (16) that wherein is wound with coil (15) is fixed on above the barrier film (3) by pad (17), nut (18), nut (19).Permanent magnet among the figure (10) selects for use the Y20 type to have the anisotropy magnet steel of through hole, its axial bottom part is bonded with back-up ring (13), the upper-end surface is bonded with cylindricality magnet case (12) so that magnetic is concentrated, make cylindricality magnet case (12) and permanent magnet (10) through hole form annular gap simultaneously, by magnet holder (11) with this partial fixing on the pump housing (1), cylindricality magnet case (12) is partially submerged in the endoporus of coil carrier (16) after fixing.
Utilize pipe joint (2) that this pump is serially connected with in the circulation loop when using this pump, pass to 50 He Zhi Ac for coil (15), then under the magnetic field interaction that alternating magnetic field that coil (15) produces and permanent magnet (10) produce, make coil (15) produce vibration, interlock coil carrier (16) passes to liquid or gas in barrier film (3) the push-and-pull pipeline, make it to flow, finish the proper functioning of this pump by certain orientation.With reference to accompanying drawing specifically when the positive half cycle of power supply during by coil (15) (establish and move upward), also along with making progress, the pump housing negative pressure occurs in (1) to barrier film (3), and expulsion valve this moment (b) cuts out, inspiration valve (a) is opened, and liquid enters in the pump housing (1).When the negative half period of power supply passed through coil (15), barrier film (3) is extruding downwards, and inspiration valve (a) cuts out, and expulsion valve (b) is opened, and liquid is forced out, and goes round and begins again, and finishes circulation.
It is 10 watts pump that the inventor has made a kind of electric power with such scheme, and it is 220 volts mains supply with frequency 50 He Zhi, voltage.Permanent magnet (10) is selected No. 401 magnet steel of Y20 type for use, and the weight sum of its coil (15) and coil carrier (16) only is about 36 grams, has realized deciding the miniaturization of power cycle pump, is specially adapted to the warm water circulation of northern resident's winter heating household small-size boiler.
