【発明の詳細な説明】
本発明は圧力気体を使用して液体を圧送するようにした
液体用ポンプに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid pump that uses pressurized gas to pump liquid.
従来、薬液が循環する径路中に設“置される液体ポンプ
は、耐腐蝕性の材料で構成したロータリ型或いは軸流型
のものが多用されてきたつこの種のポンプは、液体中で
ロータ等を回転させるものであるから、その回転に伴な

止することは不可能であり、また回転を外部から与える
必要上軸シール部分が存在し、その部分からの液体の漏
れが生じていた。Conventionally, liquid pumps installed in the path where chemical solutions circulate have often been rotary or axial flow types made of corrosion-resistant materials. Since it rotates, it is impossible to prevent dust generated from the sliding parts due to the rotation from getting mixed into the liquid, and there is an upper shaft seal part that needs to be rotated from the outside. However, fluid was leaking from that area.
本発明は上記問題点を解消するもので、以下、本発明の
実施例を図によって説明する。The present invention solves the above problems, and embodiments of the present invention will be described below with reference to the drawings.
図に示す実施例では容器を２個使用しており、各容器１

管路１ ｃ 、 ２ｃを設ける。In the embodiment shown in the figure, two containers are used, each container having one
, 2, liquid return pipes 1a, 2a and pressure feeding pipes 1b, 2.
In addition to piping b, pressure gas introduction pipes 1 c and 2 c for pumping the liquid are provided.

容器１，２内の液面を検査してパルプの開閉を制御し、
液体を圧送すべき容器を交互に選択するものである。Then, stop pulp V3゜v4 and stop pulp V7tV8 are interposed in the return pipes 1a, 2a and pressure feed pipes 1b, 2b of the containers 1, 2, respectively, and the pressure feed pipes 1b, 2b
The return pipes 1a and 2a are connected to a load to form a circulation pipe. Furthermore, stop pulp V5. At the same time as installing V6, pulp V
5. Need V6? Connect Revalp v9, pressure reducing valve 5, and filter 6. Stop Pulp ■1. v2 is a gas vent valve, and pulp V3. It works in conjunction with V4 and takes the same open/close state as this pulp. 3 is the upper limit liquid level sensor, 4
is a lower limit liquid level sensor, and these sensors 3 and 4 inspect the liquid level in the containers 1 and 2 to control opening and closing of the pulp,
The container to which the liquid is to be pumped is selected alternately.
次に本発明の実施例の動作について説明する。Next, the operation of the embodiment of the present invention will be explained.
図示の状態では、容器１を負荷よシ帰還した液を収容す

使用している。この状態ではストップパルプｖ１．Ｖ３

して負荷に圧送される。In the illustrated state, the container 1 is used as a container for storing the liquid returned from the load, and the container 2 is used as a container for pumping the liquid. In this state, stop pulp v1. V3
．． V6. V8 is open and stop pulp V2. ■4. v5
．． v7 is closed. The liquid returned from the load is pulp v3
is guided into the container 1 through the passage. On the other hand, pressurized gas is introduced into the container 2 through the stop pulp v6, the pressure inside the container 2 increases, and the liquid is forced into the load through the pulp V8 and the pressure feed pipe line 2b.
ここで容器２内のセンサー４が下限液面を検出し、容器
１内のセンサー６が上限液面を検出すると、ストップパ
ルプＶＩ、ｖ３．ｖ６．Ｖ８が閉となり、ストップパル

１内の液体がパルプＶ７を通り圧送管路１ｂを通して負
荷に圧送され、負荷より帰還した液体は戻り管路２ａを
通して容器２内に収容される。Here, when the sensor 4 in the container 2 detects the lower limit liquid level and the sensor 6 in the container 1 detects the upper limit liquid level, the stop pulp VI, v3. v6. V8 is closed and stop pulp v2. V4. ■5. ■ 7 is opened, container 1 is switched to liquid pumping, and container 2 is switched to liquid storage. The liquid in container 1 passes through pulp V7 and is pumped to the load through the pressure feeding pipe 1b, and the liquid returns from the load. is accommodated in the container 2 through the return line 2a.
尚揚程は圧送用気圧の圧力、換言すれば減圧弁５の調整
によシ行い液体の比重が１の場合、０５ｋｌ／−で５ｍ
の揚程となシ従来のポンプより数倍の能力を有すること
となる。さらに流量はニードルパルプ９で可変でき、能
力調整が非常に容易になる。In addition, the lift height is determined by the pressure of the pumping pressure, in other words, by adjusting the pressure reducing valve 5. If the specific gravity of the liquid is 1, it is 5 m at 05 kl/-.
The pump has a lift several times the capacity of conventional pumps. Furthermore, the flow rate can be varied with the needle pulp 9, making capacity adjustment very easy.
以上のように本発明は−の容器内に負荷より帰還した液

ことができる効果を有するものである。As described above, the present invention stores the liquid returned from the load in one container while transporting the liquid in the other container with pressure gas. Since there are no frictional parts, it has the effect of preventing the generation and diffusion of dirt in the liquid being pumped, increasing corrosion resistance, and increasing durability.
