【発明の詳細な説明】 〔産業上の利用分野〕 本発明は空気利用の圧力タンクを有する自動式ポンプ装
置に関するものである。Description: TECHNICAL FIELD The present invention relates to an automatic pump device having a pressure tank for utilizing air.
従来のこの種自動式ポンプとしては、第4図に示すよう
にポンプ1からの送水管6の下端を圧力タンク9内へ臨
ませ、送水管6の下端直下と吐出口10との間に平坦な邪
魔板51を設けたものがある。As a conventional automatic pump of this type, as shown in FIG. 4, the lower end of the water supply pipe 6 from the pump 1 is exposed to the inside of the pressure tank 9, and a flat surface is provided between the lower end of the water supply pipe 6 and the discharge port 10. Some have a baffle plate 51.
また、実公昭53−41773号に示すように、圧力タンク内
に送水された水をカップ状の水受部で受けることによ
り、水に混在している空気を分離するようにしたものが
知られている。Also, as shown in Japanese Utility Model Publication No. 53-41773, it is known that air mixed in water is separated by receiving water sent into a pressure tank at a cup-shaped water receiving portion. ing.
一般に、自動式ポンプ装置では、第4図に示すように、
送水管6の下端部を、空気補給装置7に補給される空気
の過剰補給防止のため、ある特定の位置にしなければな
らず、水面より上方に位置する場合がある。Generally, in an automatic pump device, as shown in FIG.
The lower end of the water supply pipe 6 must be at a specific position in order to prevent excessive replenishment of the air replenished to the air replenishing device 7, and may be located above the water surface.
そのため、送水管6の下端が水面より上方に位置した状
態にて、ポンプ1を回転させて送水管6より水を吐出す
ると、圧力タンク9内の空気が送水管6より吐出される
水に巻き込まれて、空気水面下に至る。Therefore, when the pump 1 is rotated and the water is discharged from the water supply pipe 6 with the lower end of the water supply pipe 6 positioned above the water surface, the air in the pressure tank 9 is caught in the water discharged from the water supply pipe 6. The air reaches below the surface of the water.
したがって、従来の自動式ポンプ装置では、ポンプ1の
送水量が多い場合に、第4図に示すとおり、圧力タンク
9内の空気が邪魔板51の側面を迂回して第3図Bに示す

気を十分に残留させることができなくなり、圧力タンク
9の機能を損うという問題点があった。なお、第4図
で、第1図と同一符号のものは同一物を示す。Therefore, in the conventional automatic pump device, when the water supply amount of the pump 1 is large, the air in the pressure tank 9 bypasses the side surface of the baffle plate 51 as shown in FIG. 3B as shown in FIG. It will be mixed in the discharge port 10. Therefore, in the conventional automatic pump device, there is a problem that air cannot be sufficiently left in the pressure tank 9 and the function of the pressure tank 9 is impaired. In FIG. 4, the same symbols as those in FIG. 1 indicate the same items.
また、実公昭53−41773号に示す圧力タンクの構造で
は、送水管の下端が水面より上方に位置した状態では、
送水管からの送水量が多い場合、カップ状の水受部から
いきおいよく飛散した水に圧力タンク内の空気が巻き込
まれ、その水と一緒に圧力タンク内の空気が吐出口から
圧力タンク内に排出されてしまう問題点があった。Further, in the structure of the pressure tank shown in JP-B-53-41773, when the lower end of the water pipe is located above the water surface,
When the amount of water sent from the water supply pipe is large, the air in the pressure tank is entrained in the water that is splashing well from the cup-shaped water receiver, and together with the water, the air in the pressure tank is discharged from the discharge port into the pressure tank. There was a problem that it was discharged.
本発明の目的は、簡単な構成で、圧力タンク内の空気残
留を確実なものとすることである。It is an object of the invention to ensure air retention in the pressure tank with a simple construction.

設定することにより、達成される。The above object is to provide a pressure tank, a pump provided on the pressure tank, a steam separation chamber provided on the discharge port side of the pump, and discharge water from the separation chamber into the pressure tank. A discharge pipe is provided so as to hang down on the pressure tank, and a water supply pipe that is connected to this discharge pipe and is provided so as to hang down from the upper surface to the lower surface inside the pressure tank. In an automatic pump device having a curved surface protruding toward the upper surface of the pressure tank and having a plurality of discharge ports at the lower portion of the side surface of the pressure tank, the water supply pipe is provided on the side surface side from the center of the pressure tank. While displacing the water supply pipe, between the discharge port immediately below the water supply pipe and the discharge port closest to the part directly below the water discharge pipe, and at a position close to immediately below the water supply pipe, An inner curved surface is located immediately below the water pipe. A semi-cylindrical air levitation plate is arranged, and the height of the air levitation plate is set so that the upper end of the air levitation plate is located below the lower end of the water supply pipe. To be done.
圧力タンク内の空気が送水管より吐出された水に巻き込
まれても、その空気を巻き込んだ水は、圧力タンクの下
面で放射状に広がる。そして、空気浮上板側に向って広
がった水は、大きく広がらないうちに空気浮上板に衝突

離して圧力タンクの上方に浮上してしまうため、送水管
より吐出された水によって巻き込まれた圧力タンク内の
空気が吐出口から流出することはほとんどない。Even if the air in the pressure tank is caught in the water discharged from the water pipe, the water entrained in the air spreads radially on the lower surface of the pressure tank. The water that has spread toward the air levitation plate collides with the air levitation plate before it spreads significantly, and the air contained in the water is separated and floats above the pressure tank. Also, since the water that spreads away from the air levitation plate is away from the discharge port of the pressure tank, the air contained in the water separates and floats above the pressure tank while it spreads. Therefore, the air in the pressure tank that is caught by the water discharged from the water supply pipe hardly flows out from the discharge port.
圧力タンクの下面は、圧力タンクの上面に向って突出す

ても、その空気浮上板の下端を圧力タンクの下面に隙間
なく接触させることが容易であって製作性がよい。Since the lower surface of the pressure tank is a curved surface that projects toward the upper surface of the pressure tank, even if the air levitation plate is a semi-cylindrical shape, make sure that the lower end of the air levitation plate is in contact with the lower surface of the pressure tank without a gap. Is easy and has good manufacturability.

内径より大きく設定してある。In the drawing, a pump 1 is provided so as to suck well water or the like from a suction port 2 through a check valve 3, discharge it to a steam separation chamber 4, and further discharge it from a discharge pipe 5 to a water supply pipe 6.
The lower end of the water supply pipe 6 faces the inside of the pressure tank 9. The automatic air supply device 7 communicates with the suction part of the pump 1 via the conduit 8 and supplies air to the discharge pipe 5 by continuing the pump 1. The pressure tank 9 has three discharge ports at the bottom of its side surface.
10,11,12 are provided. In this embodiment, the discharge port 1
1,12 are closed by blind plate 13. The air floating plate 21 is the water pipe 6
Is attached to the lower surface of the pressure tank 9 and is located immediately below the discharge port 10 and closest to the discharge port 10. The lower surface of the pressure tank 9 is a curved surface that projects toward the upper surface of the pressure tank 9. The air levitation plate 21 is formed in a substantially semi-cylindrical shape having an inner curved surface right below the water supply pipe, and its inner diameter is set to be larger than the inner diameter of the opening of the water supply pipe 6.
送水管6の下端部は、空気補給装置7に補給される空気
の過剰補給防止のため、ある特定の位置にしなければな
らなく、水面より上方に位置する場合がある。The lower end of the water supply pipe 6 must be at a specific position to prevent excessive replenishment of the air replenished to the air replenishing device 7, and may be located above the water surface.

を使用する場合も同様である。Thus, when the pump 1 is rotated to discharge water from the water supply pipe 6 with the lower end of the water supply pipe 6 positioned above the water surface, the air in the pressure tank 9 is discharged from the water supply pipe 6. Even if you get caught in water, it reaches below the surface of the air. The water containing the air spreads radially at the bottom. The water that spreads to the side of the air levitation plate 21 collides with the air levitation plate 21 as shown by the arrow in FIG. 1 and moves upward, and part of it is caught in the center direction as shown in FIG. , The air is separated upward and immediately rises upward. Water containing air that spreads to the opposite side of the air levitation plate 21 is discharged from the outlet as shown by the arrow in FIG.
Since it spreads in the direction away from 10, the air separates at that time and floats upward. As a result, only water containing almost no air flows into the discharge port 10, which can be remarkably improved as compared with the conventional example B as shown in FIG. 3A. When using the discharge port 12, the water flow containing air on the opposite side of the air levitation plate 21 swirls toward the discharge port 12, but the air floats before reaching the discharge port 12 because the distance is far. Only water flows in. Discharge port 11
The same applies when using.
