It has the advantage that it can also be used for priming water. However, if the cross-sectional area of the suction pipe is large, surface waves are likely to be generated on the liquid level in the pipe due to vibration of the vibrating pipe, and the vibration force is consumed in exciting the surface waves, making it impossible to raise the liquid column. was there.

端まで上昇する。■ When the valve plate/Hiro is vibrated so as to follow the vibrating tube S ■ The rising process of the liquid level The valve plate/41 is the vibrating tube J! Let the vibration tube follow this motion! When the liquid is moved up and down, the liquid level inside the tube also moves up and down as the pressure of the air column inside the tube fluctuates. This vertical movement of the liquid level is accompanied by the vibration phenomenon of a type of spring-mass system consisting of the elasticity of the air column and the mass of the liquid column.Therefore, since the damping due to friction is small, the vibration of the vertical movement of the vibrating tube 5 is If the number is set to the natural frequency of the air column-liquid column system inside the tube, the pressure of the air column inside the tube will become extremely high. Therefore, if you rub the valve so that it opens above a certain set pressure, the valve will open when the air column pressure inside the pipe exceeds the valve's set pressure, and the upper limit of the air column pressure will be maintained at the valve set pressure. The average value of the air column pressure during the periodic oscillation becomes below atmospheric pressure, and the liquid column rises corresponding to the pressure decrease. This occurs continuously and the liquid level rises to the upper end of the vibrating tube 3.

圧力は低下し管内の液面は上昇する（第ｊ囚）。θ Vibrating tube with the valve port closed due to the valve plate lhiro! When the temperature rises, the air in the vibrating tube and the stationary tube expand, the pressure in both tubes decreases, and the liquid level in the tubes rises (case j).

コ内圧力は低下し液が上昇する。Furthermore, when the vibrating tube descends, the liquid in the vibrating tube and the stationary tube a does not fall much due to the inertia of the liquid. Therefore, at this time as well, gas is discharged to the top, the vibration V and the pressure inside the stationary tube decrease, and the liquid rises.

れることとなる。Due to this action, pressure fluctuations caused by the vibrating tube or valve plate are transmitted into the liquid when it is full of liquid, and into the gas when it is not full, and the pressure fluctuations caused by the vibrating tube or valve plate are transmitted to the gas or gas when the liquid is not full. Waves are generated, but the pressure standing waves are caused by the valve plate/F
Since the fluctuating pressure is large at the part and decreases at the lower part of the stationary pipe =, liquid or gas escapes from between the valve plate /4t and the valve seat /3 to the upper part. Similarly, by repeating the conditions from ■ to ○, the liquid will eventually reach the upper end of the vibrating tube 5, and as the vibrating tube descends as shown in Figure 3, the liquid will overflow into the valve casing, and the liquid will overflow into the valve casing. Casing // Discharge port 9 from inside
The liquid will flow in the direction of , and then the liquid will be pumped and discharged.

ない。Due to such a pump action, if there is a liquid level inside the stationary tube and the vibrating tube S vibrates, if there is a liquid level in the large diameter part of the stationary tube, the liquid in the tube will vibrate if surface waves are generated. A part of the energy vibrating the tube 5 is dissipated for the generation of the surface waves. However, due to the float/6, the liquid level in the tube is narrowed so as not to generate surface waves, so no surface waves occur.

６図のＡ−Ａ部分の外周を切断して見る斜視図である。FIG. 6 is a longitudinal sectional view of another embodiment of the present invention, and FIG. 7 is a perspective view of the outer periphery taken along the line AA in FIG. 6.

除け１９は静止管コの大径部の直径の位置にある。At the upper end of the large diameter section of the stationary tube v2, a part of the tube wall at the upper end of the small tube /7 is made to protrude so as to reach the boundary wall /Kl between the large diameter section and the small diameter section of the stationary tube λ to serve as a wave shield. It is. In this example, the wave shield 19 is located at the diameter of the large diameter portion of the stationary tube.

あるため表面波は生じない。According to this embodiment, since the large diameter portion of the stationary tube is divided into small tubes 17, no surface waves are generated. Furthermore, even when the liquid level reaches the space near the wall /g at the boundary between the large diameter part and the small diameter part, no surface waves are generated because there is a wave shield.
実施例は吸込管中、静止管が拡大管となった場合をのべ
たが振動管と静止管が等しくても管の断面積が大きいと
表面波が生ずるのでこのような場合もこの発明に含まれ
ることはいうまでもない処である。The embodiment describes the case where the stationary tube becomes an expanding tube in the suction tube, but even if the vibrating tube and the stationary tube are equal, if the cross-sectional area of the tube is large, surface waves will occur, so such a case is also included in the present invention. Needless to say, this is a place where you can get lost.

い。In the embodiment, a vibrating column pump in which the lower end of the vibrating tube communicates with the water reservoir through the stationary tube has been described, but if the lower end of the vibrating tube is not provided with a stationary tube and is directly immersed in the water reservoir, the longitudinal cross-sectional view in Fig. g is used. In this case, the action of the float is the same as in the first embodiment, and also in the figure, a collection of small tubes like the one in the first embodiment is constructed in the enlarged lower part of the vibrating tube. It's okay.

形でもよいのである。As described above, in the present invention, when a float is floated by dividing the liquid level in the suction pipe of a vibrating column pump into one section, the liquid level in the pipe becomes a small area and surface waves are prevented. Also, if the suction pipe is a collection pipe of small pipes, the surface area of the liquid inside the small pipes is small, so the generation of surface waves is prevented, and the part of the suction pipe that communicates from the large diameter part to the small diameter part is divided into two parts by a wave shield, reducing the surface area. Since this is almost the same as the large diameter portion of the suction pipe, the generation of surface waves is prevented. It is sufficient if the liquid level inside the suction pipe can be divided in this way and the generation of surface waves can be prevented by this division, so dividing the liquid level inside the suction pipe means that each part is completely separated by a closed line. Instead, it may have an opening that allows communication between the separate liquid surfaces, as if it were a breakwater.

面を上昇させることのできない大きな管径の吸込管でも
液面上昇をさせることが可能になる効果を生じた。Since the present invention includes means for reducing the surface area of one sectioned liquid in the suction pipe of the vibrating column pump, it is possible to significantly prevent loss of vibration force of the vibrating tube. Moreover, it has become possible to raise the liquid level even in a suction pipe with a large diameter, which has hitherto been unable to raise the liquid level.
吸込管中に浮子を浮かせるのは極めて簡単である。It is extremely easy to float the float in the suction pipe.
多数の小管を集合させて吸込管の下端を構成するとスト
レーナの機能を兼ねることができる。If a large number of small tubes are assembled to form the lower end of the suction tube, it can also function as a strainer.
