本発明は交流電磁石を用いた電磁往復ポンプに関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electromagnetic reciprocating pump using an AC electromagnet.
従来空気供給用として用いられている電磁往復ポンプと

動し、ダイヤフラムポンプ５ａ 。As shown in FIG. 1, an electromagnetic reciprocating pump conventionally used for air supply has two right and left rhombic diaphragms 'la' and 'lb on the lower surface of the upper edge of the formwork 1, and rubber 5a, Support M4a', 4b via 3b
A dia slam pump 5a is installed vertically in the center of the pump.
, 5b are attached facing inward, and two magnetized permanent magnets 6α, 6b are attached to the horizontal lower surface (two magnetized permanent magnets 6α, 6b), and an AC electromagnet 7 having a core is mounted opposite to the permanent magnets 6a, 6b. When an AC voltage is applied to the AC electromagnet 7, which is screwed to the upper surface of the lower edge of the frame 1, the diaphragms 2α and 2b vibrate from side to side from the vertical upper end support as shown in FIG. Pump 5a.

力を充分（二出し得ない゛等の欠点がある。5b. Therefore, in order to increase the capacity of the pump, that is, the suction pressure and the discharge pressure, the AC electromagnet 7 and the permanent electromagnets 6a and 6b must be made larger. In this case, the pump becomes larger, which increases power consumption and is uneconomical.Also, since the magnetic force of the AC electromagnet 7 is not effectively used, there are disadvantages such as not being able to obtain sufficient pump capacity. .
本発明は斯る点に鑑みてなされたもので、左右の振動板

ある。The present invention has been made in view of this point, and includes connecting the vertical lower ends of the left and right diaphragms with a connecting member that allows the oscillating diaphragms to maintain substantially the same interval and vibrate together in the same direction. Therefore, even if a load is applied to the pump, both diaphragms vibrate in the correct position, increasing the pumping capacity.
以下本発明の実施例を図面について説明する。Embodiments of the present invention will be described below with reference to the drawings.
第３図は左右の振動板２１！ 、 ’ｌｂを垂直部下端

る。When the permanent magnets 6a and 6b are connected by the linking member 11 in this manner, the magnetic force of the AC electromagnet 7 can be used most effectively. That is, when an AC voltage is applied to the AC electromagnet 7, the diaphragms 2a, 26 vibrate more rapidly than when the conventional diaphragms vibrate separately, as shown in FIGS. 4 and 5. In sb, since the diaphragms 2α and 2b vibrate in the same direction, their vibrating force has a synergistic effect, that is, they push them together and pull them together.To explain in more detail, in FIG. 4, the N of the permanent magnet 6b The attraction force caused by the S pole of the core 14c of the AC electromagnet 7 and the attraction force caused by the S pole of the permanent magnet 6a via the link 11 and the N pole of the core 14b are added, and the diaphragm 5a is moved with a large force. 5, the capacity of the pump itself increases, with the exact opposite action shown in FIG. According to the experimental results, 1.5 for the same shape
I gained twice the power. Even when a load is applied as shown in FIGS. 5 and 6, the magnetic force between the permanent magnet and the AC electromagnet is effectively utilized without operating like the diaphragm in this case.

のうえ連結部材としての動作が無理なく行われるので耐
久性を有するという利点がある。In FIG. 6, a connecting member 15 made of an elastic body such as synthetic rubber or a coil spring is used as the connecting member. If an elastic body is used as the connecting member in this way, it will have some expansion/contraction and bending action, so the diaphragm pumps 5a, 5b
The synergistic effect of the forces that vibrate is performed more reliably, which is better than the connecting member 11 using the link shown in the previous embodiment, and it also has the advantage of being durable because it operates smoothly as a connecting member.

In the formed circumferential grooves 17a, 17M, synthetic resin bushings 19a, 19/l may be inserted and supported through the through holes 18Q, 186 of the diaphragms 'la, 2b to prevent wear. In addition, as shown in FIG. 8, a connecting member 15 made of an elastic body is used as a vibration-proof rubber bellows with a bellows in the center, and head screws 20Q and 20b are embedded in both ends of the bellows and protrude. The through hole 21a has a vibration frequency of 26.

増大することができる。The ones shown in FIGS. 11 to 13 are diaphragms 'la,
Elastic plates 26tL and 26b are connected to the vertical lower end of the diaphragm 2α and 2b in a vibration direction perpendicular to the diaphragms 2α and 2b, and a connecting member 15 made of an elastic body is attached to both ends of the elastic plates 26tL and 26b. With such a configuration, it goes without saying that the permanent magnets 6a and 6b effectively utilize the magnetic force of the electromagnet 7 during operation, that is, when an AC voltage is applied to the AC electromagnet 7 and a load is applied to the pump. In this case, as shown in FIG. 13, the diaphragm pump 5b is first pushed by the diaphragm 2b, and the vibration generated by the diaphragm 'la (2) is transmitted to the elastic plate 26b via the combination body 15 of both the elastic plates 26a. is transmitted with a slight phase delay, pushing the diaphragm pump 5b, and as a result, the diaphragm pump 5b is vibrated by the two forces of the permanent magnets 6α and 6b, and an extremely large vibration force is applied to the diaphragm pumps 5a and 5bl. Double-addition pump capacity can be maximized.

ものである。It goes without saying that the connecting member 15 may be a connecting member using a link or a connecting member using an elastic body. Further, in this embodiment, it is possible to connect the connecting member 15 only to one end of the elastic plates 26th and 26b, but in this case, the pumping capacity is not much different from that of the previous embodiment. Of course, these are included in the present invention.

の形状。As described above, the present invention provides an electromagnetic reciprocating pump in which two diaphragm pumps are mounted inwardly and a diaphragm connected to the diaphragm pump is vibrated by an AC electromagnet, and the diaphragm is connected to the diaphragm pump. By connecting the diaphragms with the connecting member so that the diaphragms can vibrate while maintaining the same spacing when vibrating with the connecting member, the conventional shape is achieved.

発明である。It is economical because the pump capacity can be increased by size without increasing the size of permanent magnets or AC electromagnets.
On the other hand, it has various effects such as preventing the C1 diaphragm from colliding with the pump load as in the conventional case, and is an invention of extremely practical value.
