Description

—种带回流槽的电磁柱塞泵 - kind of electromagnetic piston pump back to launder

技术领域 FIELD

[0001] 本实用新型涉及一种水泵,具体是一种带回流槽的电磁柱塞泵。 [0001] The present invention relates to a pump, in particular an electromagnetic piston pump back to the flow cell.

背景技术 Background technique

[0002] 传统的柱塞式水泵由于自身结构的特性,无法适应小型、微型产品中;目前小型的柱塞式电磁水泵在各个领域得到了广泛的应用,特别是微型柱塞式水泵以其结构小巧精密得到了广泛应用,它可以应用在咖啡机、蒸汽发生装置上,特别在抽油烟机蒸汽自动清洗装置上的应用。 [0002] The traditional plunger type pump due to the characteristics of the structure itself, unable to adapt to small, micro products; the current small plunger-type electromagnetic pumps have been widely used in various fields, especially micro-plunger pumps its structure small precision has been widely used, it can be applied in the coffee machine, a steam generating device, an application on the device, in particular an automatic cleaning steam hood. 柱塞式电磁水泵的原理是:柱塞芯不是利用曲轴带动的,而是在外部电磁场力及内部弹簧的回复力的作用下,进行往复的运行,加上柱塞芯上带有单向阻塞液体流向的胶塞,使液体流过柱塞芯时只有向出水口方向流出,而不能反方向流出,从而达到泵水的功能。 Electromagnetic pump plunger principle is: the crank plunger core is not driven, but under the action of the restoring force of the external electromagnetic field and the force of the internal spring, reciprocating operation, together with the unidirectional blocking plunger core only when the liquid flows out of the plug flow, the liquid flow through the plunger core to the outlet direction, and can not flow out the opposite direction, so as to achieve the pumping function. 其中外部电磁场是由正弦交流220V经过半波整流通过电磁线圈提供的,电磁场仅对柱塞芯施加向后运动的拉力(向后运行),从而使柱塞芯向内部的弹簧施加向后的压缩力,同时水经过柱塞芯内部通道被吸入到压力仓内,而当半波电磁场作用完后,柱塞芯因受到内部弹簧的回复力的作用,往压力仓内部运行,仓内空间瞬速减小,水被压出压力仓,向出水口排出;当水进入柱塞泵内部的吸水管时,由于柱塞泵芯 Wherein the external force field is moving backward (backward run) by a sinusoidal AC 220V is applied after half-wave rectification provided by a solenoid, plunger core field only, so that the plunger core is applied to the interior of the compression spring rearwardly force, while the water passes through the internal passageway of the plunger core is drawn into the pressure cartridge, and when the half-wave after the electromagnetic field, due to the restoring force by the action of the internal spring plunger core, the internal pressure of the cartridge to the operation, the cartridge space instantaneous speed reduced pressure water is pressed out of the cartridge, is discharged to the outlet; when water enters the interior of the piston suction pipe, since the piston core

[0003] 是在吸水管内往复运动的,而且频率和速度都很快,达到每秒钟内往复25次,而泵芯与管壁之间的间隙只有约0.15mm的距离,然而现有的柱塞式水泵的泵芯却是圆柱型结构,当泵芯在管壁之间高速来回运行时,水在泵芯与管壁之间必须来回顺畅流动,水对泵芯的阻力才会最小,但是泵芯与管壁之间的间隙距离只有0.15mm实在很小,水在这之间高速来回流动是很难的,故对泵芯来回往复运行的阻力是非常大的,这样就会大大消耗了实际的电磁能,降低了整个水泵的效率,在同等功率下,排水量大大减小,但如果用减小圆柱的直径或增大管径来增大之间的间隙距离来减小水的阻力来提高效率的话,是不能的,因为泵芯与内部的导磁环之间的距离越小,电磁力作用在泵芯上的磁力才会越大,电能转换成动能才会越大,效率才会越高,反之越小,效率降低 [0003] In the suction pipe is reciprocating, and the frequency, and are quick to reach 25 per second shuttle, and the gap between the core and the wall of the pump only a distance of about 0.15mm, whereas the conventional column pump pump core plug is cylindrical structure, when a high-speed pump core run back and forth between the tube wall, the water must flow smoothly back and forth between the pump and the wall of the core, the resistance of the water pump will be minimal core, but the gap distance between the core and the wall of the pump only 0.15mm too small, the water flows back and forth between a high speed is difficult, so the resistance to the back and forth operation of the pump core is very large, this will be greatly consumed the actual electromagnetic energy, reducing the efficiency of the pump, at the same power, the displacement is greatly reduced, but if the gap distance is reduced cylinder diameter or increasing diameter to increase between the resistance of the water is reduced to efficiency, it is impossible, since the distance between the core and the permeable ring pump inside, the larger the magnetic core before the pump electromagnetic force, the greater the electrical energy is converted into kinetic energy will, efficiency will the higher, the smaller the contrary, reduced efficiency 磁损与距离R2成正比,因此不能用减小圆柱的直径或增大管径的方法来提高效率,故需要对现有水泵作进一步改善。 Magnetic loss is proportional to the distance R2, and therefore can not be increased or reduced diameter cylindrical diameter methods to improve the efficiency, it requires further improvement of existing pumps.

[0017] 所述的回流槽51截面呈圆弧状,均匀阵列分布在阀芯的表面。 51 cross-section according to reflux [0017] arcuate groove, uniform array across the surface of the valve body.

[0018] 所述的回流槽51截面呈矩形状,均匀阵列分布在阀芯的表面。 The cross section of the groove at reflux for 51 [0018] surface of the rectangular shape, distributed in a uniform array spool.

[0019] 所述的回流槽51截面呈三角状,均匀阵列分布在阀芯的表面。 51 is a cross-sectional backflow groove of the [0019] triangular shape, an array of uniformly distributed on the surface of the valve body.

[0020] 所述的阀芯5的直径与抽水管4内部的直径差控制在0.2mm至0.3mm之间。 [0020] The spool 4 the diameter difference between the inner diameter of the suction pipe 5 is controlled between 0.2mm to 0.3mm.

[0021] 所述的阀芯5内部贯通设置有导水孔52,导水孔52的出口设置有止回阀53。 [0021] 5 through the interior of the valve body guide hole 52 is provided with a water outlet of the water guiding holes 52 is provided with a check valve 53.

[0022] 工作原理:受到电磁力做功原理的影响,线圈与导磁环6,导磁环6与阀芯间的距离越小,线圈作用于阀芯上功的效率也就最高,因此缩小两者间的间隙是提高效率最直接的办法。 [0022] The working principle: affected by the electromagnetic force acting principle, the magnetic ring coil 6, the distance between the magnetic ring and the valve body 6 is smaller, the coil on the spool acting in work efficiency also the highest, so two reduction the gap between those who are the most direct way to improve efficiency. 因此就需要令阀芯与抽水管间的间隙在满足阀芯滑动的前提下越小越好,但是随着两者间的距离缩小,阀芯与抽水管间的摩擦力也就越大,因此水泵工作时阀芯摩擦产生的热量会令电磁线圈快速升温,阻抗降低,导致水泵的功率下降,从而导致水泵的出水量不大大减少,与此同时,随着间距的缩小,阀芯运动的阻力也就越大,因此也需要加大线圈的功率才能满足水管工作需要,导致水泵耗电量增大。 Hence the need to make the gap between the valve body and the suction pipe in the premise of meeting the slide valve element as small as possible, but as the distance between the two is reduced, the friction between the valve body and the greater the suction pipe, so the pump when the valve body work friction heat will make rapid heating electromagnetic coil, the impedance decreases, resulting in decreased power of the pump, causing the pump does not significantly reduce the amount of water, at the same time, reducing the gap with the resistance, the spool movement may also the greater, and therefore need to increase power to the coil to meet the needs plumbing work, leading to the pump power consumption increases. 为解决上述技术难题,本实用新型中在阀芯的表面开设有若干贯穿其前后两端的回流槽,在阀芯滑动过程中,令泵水进入回流槽内,使其起到水润滑的作用,降低水阀的运动阻力,令阀芯自由运动的同时,在提高整个水泵的排水效率的同时,泵水还能吸收阀芯及电磁线圈产生的热量,避免因电磁线圈升温导致的功率下降。 To solve the above problems, the present invention defines a plurality of slots therethrough reflux front and rear ends of the surface of the valve body, the valve body in the sliding process, so that the pump water into the reflux tank, so that the water plays the role of lubrication, reducing the motion resistance of the valve, the valve body so that free movement while improving efficiency of the drainage pumps at the same time, the water pump and the valve body can absorb the heat generated by the electromagnetic coil, to avoid power drop due to temperature rise caused by the electromagnetic coil. 与此同时,本实用新型中阀芯与抽水管间的间隙可以设置到最小间隙,从而提高水泵的工作效率。 At the same time, the gap between the valve body and the suction pipe of the present invention can be set to a minimum gap, thereby improving the working efficiency of the pump.
