が振動管１の上端より流出する。By the vertical movement of the vibrating tube 1, the following pump action substantially similar to the conventional one is performed. When the valve 3 moves following the vibrating tube 1: (i) Ascent process of the liquid level When the valve 3 moves following the vibrating tube 1 and the vibrating tube moves up and down, the air column in the tube The liquid level in the pipe moves up and down with the change in pressure. This vertical movement of the liquid surface is accompanied by the vibration phenomenon of a kind of spring-mass system composed of the elasticity of the air column and the mass of the liquid column. When the tube is set to the natural frequency of the gas column-liquid column system in the tube, the pressure of the gas column in the tube becomes very high. Therefore, if the valve 3 is opened above a certain set pressure, the valve will open when the air column pressure in the pipe becomes higher than the valve 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 per shaking cycle is equal to or lower than the 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 1. (ii) Liquid discharging process After the liquid surface reaches the upper end of the vibrating tube 1, the liquid column pushes up the valve by the inertial force acting on the liquid column in the tube from the vibrating tube 1, and the liquid flows from the upper end of the vibrating tube 1. leak.

At the upper end, there is a slight gap between the vibrating tube 1 and the valve 3. (ii) When the vibration tube 1 reaches the lower limit, the valve 3 catches up and closes the valve port. (iii) Next, when the valve port is closed by the valve 3 and the vibration tube 1 rises, the liquid rises together with the vibration tube 1. (iv) When the vibrating tube 1 further descends, the liquid in the vibrating tube 1 does not drop much due to the inertia of the liquid.

なる。 As described above, the present invention has the following advantages. A permanent magnet magnetized in the radial direction and having different magnetic poles is alternately arranged at intervals in the axial direction of the tube on the outer periphery of a vibrating tube made of a magnetic material to form a mover. A plurality of stators each having an electromagnetic coil installed in an electromagnetic yoke of a mold are fixedly arranged in the axial direction of the tube, and a vibrating means for reciprocatingly moving the mover slidably in the axial direction of the tube is provided. The gap between the coil side and the mover side is closed by a small gap, so that no pumping liquid leaks and the size of the device can be reduced, and the application range of the vibrating column pump can be expanded. In addition, the magnetic
Through the conductive material, the permanent magnet, and the U-shaped electromagnetic yoke.
A magnetic circuit is formed on a section including the central axis of the moving tube (Fig. 1).
Of the vibrating tube through which the magnetic flux penetrates.
In the present invention, the magnetic flux density divided by the area is
Is made of a magnetic material.
Compared to those with cylindrical soft magnetic material attached to the outer periphery
If the outer dimensions of the vibrating tube are the same,
The magnetic flux density is small because the cross-sectional area through which the magnetic flux penetrates is large.
It will be cheap. On the other hand, in a magnetic circuit, the magnetic resistance is the magnetic flux
Is inversely proportional to the size of the cross-sectional area through which
The size of the cross-sectional area through which magnetic flux penetrates the magnetic material part of the vibrating tube
In the present invention, the magnetic resistance in the through portion is reduced.
You. As a result, a permanent magnet with the same residual magnetic flux or magnetomotive force
Can be used to increase the generated magnetic flux
Therefore, increase the thrust generated in cooperation with the electromagnetic coil.
Therefore, it is possible to improve the pump performance such as the maximum pumping amount.
It becomes possible. On the other hand, the magnetic material part forming the vibrating tube is
When the operating point with the same magnetic flux density penetrates,
Of the present invention, wherein the vibrating tube is made of a magnetic material.
Made of non-magnetic material and fitted with a cylindrical soft magnetic material on the outer periphery
The outer diameter of the vibration tube can be made smaller than that of
Therefore, it is possible to reduce the size of the vibration pump.
Become.
