That is, a negative pressure section (vacuum) was formed in the fc1 section by jetting water or air out of the Jol nozzle through the fat water supply (air) pipe, and water was pumped up from (d). but,
In the case of the water or air that creates the pumping mechanism, in the case of the former water, the lifting height is at most 4 to 5 meters from the water surface, and in the case of the latter air, the lifting height is expected to be high.
It has the drawback that air feed pressure and pressure in addition to earth and water pressure are constantly required, and the power source for this is enormous.

エダクタ一式ポンプの効率をアップしたものである。The present invention makes maximum use of the characteristics (difference in density) between water and air to improve the efficiency of an eductor pump.

高さまでの上昇する揚程高さと速度を得られる。First, the water sent from the pump passes through the water pipe (2), and then from the water hole inside the eductor (3), water at a pressure of one foot is sent to the injection nozzle (4). Water with a constant pressure is ejected from each injection nozzle in (4) in a conical shape onto the Al. Water and earth and sand flow in from the crevices.At the same time, the air outlet (7) also becomes a negative pressure (vacuum) state, so the air pressure when sending through the air pipe (5) is the feeding pressure corresponding to the negative pressure. This is a good car number.If the eductor is installed underwater, the air pipe (5) is filled with water through the air jet (7) [1] to the level corresponding to the water level. The water level of the water in the air pipe (5) drops to a pressure corresponding to the negative pressure number in (B), and the water is discharged. It passes through B) and reaches the circulation part.The water that has reached part A is pushed to the discharge port in the direction (E) by the water pressure jetted from the nozzle (4), and is finally discharged from the discharge port. As mentioned above, when the negative pressure reaches the negative pressure point in the section (7), the inside of the air pipe (1 and (5) is also affected by the negative pressure, causing the water level to drop or is discharged, but at that time, the air pressure sent to the air outlet in (7) can be at a pressure equivalent to the negative pressure in (B), so it is very small. The air coming out of (7) can mix with water, etc. flowing in from the inlet of (B) (A), or the air can rise by itself in the direction of (Bl - (A) = (G)). However, at that point, the density in (A) and (E) decreases rapidly.The (A)
(As the density in Bl decreases, the water in (A) and (E) can rise to a height and speed corresponding to the (density) of the water pressure ejected from (4).
従って本発明の特徴は、（４）のノズルから噴射される

This is an energy-saving type pump that increases water pressure and also increases the efficiency of the eductor pump with a small amount of energy (lift height, speed, pumping and discharge volume, etc.).
このエダクタ一式ポンプはエアーをも同時をこ混合排出

In addition, the difference in density of the water is also caused by convection, so the DO in the water can be made uniform.
最近問題となっている湖沼等の富栄養化防止方法として
も利用出来る。It can also be used as a method to prevent eutrophication of lakes and marshes, which has recently become a problem.
