본 고안은 벤튜리관을 이용하는 흡인장치(이하 펌핑용 벤튜리관이라 칭함)에 있어서, 입구쪽의 압력변동이나 변화시에도 고속 유체의 유속분포를 일정하게 하여 흡인압력의 변화를 줄이고, 이에 따라 흡인작용의 원활을 꾀한 벤튜리관을 제공하려는 것이다.The present invention is a suction device using a venturi tube (hereinafter referred to as a pumping venturi tube), the flow velocity distribution of the high-speed fluid is constant even when the pressure fluctuation or change in the inlet side to reduce the change in the suction pressure, accordingly the suction action To provide a smoothly venturi tube.

펌핑용 벤튜리관은 유체의 압송관로상에 설치하는 것이며, 별도의 동력없이 유체를 보조적으로 펌핑하는데 사용된다.The pumping venturi pipe is installed on the pressure feeding pipe of the fluid and is used to assist the pumping of the fluid without additional power.

위와 같은 보조펌핑이 필요한 경우를 생각해보면, 예컨데 절삭유의 순환 펌핑시 손실량을 보충하는 경우, 첨가제를 혼입하는 경우 또는 여과를 위하여 별도의 경로를 통해 절삭유를 순환시키는 경우이다.Considering the case where the auxiliary pump as described above, for example, to compensate for the loss in the circulating pumping of the cutting oil, the case of mixing the additives or circulating the cutting oil through a separate path for filtration.

펌핑용 벤튜리관은 관내에 흐르는 유체의 속도에너지를 진공력으로 바꾸는 구성이므로, 유속이 가장 빠른 소직경 목부 주변에 진공실을 만들고 진공실에 흡입관을 접속하는 구조로 되어 있다.The pumping venturi tube is configured to change the velocity energy of the fluid flowing in the tube into a vacuum force, so that a vacuum chamber is formed around the small diameter neck having the fastest flow rate, and the suction tube is connected to the vacuum chamber.

따라서, 흡인 압력은 유체의 속도 변화에 지배되는 종속성을 갖는 것으로, 입구측의 압력 변동 및 유속 변화에 대응하여 민감하게 변동되는 것이며, 이러한 결과 흡인압력의 발생효율이 저하되는 것이다.Therefore, the suction pressure has a dependency that is governed by the change in the speed of the fluid, and is sensitively changed in response to the pressure fluctuation and the flow rate change at the inlet side, and as a result, the generating efficiency of the suction pressure is reduced.

본 고안은 위와 같은 종속성에 따른 효율저하를 방지할 목적으로 고안되었다.The present invention is designed to prevent the efficiency degradation due to the above dependencies.

본 고안의 주요 기술수단은 벤튜리관의 입구측에 나선홈을 갖는 수동 회전자를 내장하는 것이다.The main technical means of the present invention is to incorporate a manual rotor having a spiral groove on the inlet side of the venturi tube.

이로써 입구측의 유체에 저항을 주며, 유압 또는 유속의 파상적인 변동성분이 유체저항이 완충되고 회전자의 회전운동 에너지로 바뀌면서 흡수되어 유속은 안정을 꾀하게 되는 것이며, 결과로써 원활한 흡인압력을 얻을 수 있게 된 것이다.This gives resistance to the fluid at the inlet side, and the fluctuations in the hydraulic or flow velocity are absorbed as the fluid resistance is buffered and converted into the rotational kinetic energy of the rotor, so that the flow velocity is stabilized. As a result, smooth suction pressure can be obtained. It is.

본 고안은 첨부도면을 인용하면서 상세하게 설명하면 다음과 같다.The present invention is described in detail with reference to the accompanying drawings as follows.

입구측 부재(1)와 출구측 부재(2)가 접합되었으며 입구측 소경목부(4)는 간극(5)을 띄워 대향되어 있고, 출구측 부재의 흡입관로(9)를 갖는 홀(6)과 입구측 부재의 돌출부(7) 사이에 진공실(8)이 구성되어 있는 벤튜리관에 있어서, 입구측 부재상의 유체유입관로에는 환턱(10)을 만들어 회전자(11)를 유동상태로 끼웠으며, 회전자의 구성은 상부평면(13)과 저부평면(14)을 갖는 회전체의 주벽에 등간격의 나선유로(12)를 형성한 것이다.The inlet side member 1 and the outlet side member 2 are joined to each other, and the inlet side small-necked portion 4 is opposed to each other with a gap 5 therebetween, and has a hole 6 having a suction pipe passage 9 of the outlet side member. In the venturi tube, in which the vacuum chamber 8 is formed between the protrusions 7 of the inlet member, a circular jaw 10 is formed in the fluid inlet pipe path on the inlet member, and the rotor 11 is inserted into the flow state. The former configuration is to form a spiral flow path 12 at equal intervals on the circumferential wall of the rotating body having the upper plane 13 and the lower plane 14.

본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention is as follows.

펌핑용 벤튜리관의 일반적인 작용을 보면 입구측 부재의 유입관로에 유체가 절대치로서 압송되면 유체는 소경목부(3)(4)를 지날 때에는 속도가 빨라져서 간극(5)으로 연통된 진공실(5) 내에는 진공력이 발생되며, 이 진공력은 흡입관로(9)에 흡인압력을 발생시키는 것이다.In general operation of the pumping venturi tube, when the fluid is pushed to the inlet pipe of the inlet member as an absolute value, the fluid is accelerated as it passes through the small diameter wood section 3, 4, and communicates with the gap 5 in the vacuum chamber 5. The vacuum force is generated, this vacuum force is to generate a suction pressure in the suction pipe (9).

본 고안에서 신설된 회전자의 작용을 보면, 상기한 입구측 부재의 유입관로에 흐르는 유체는 제일 먼저 회전자의 상부 평면(13)에 부딪친다.Referring to the action of the rotor newly established in the present invention, the fluid flowing in the inlet pipe of the inlet member hits the upper plane 13 of the rotor first.

이때의 유체저항은 유속 또는 유압의 변동성분에 대하여 완충역할을 하는 것이다.The fluid resistance at this time acts as a buffer against the fluctuation components of the flow rate or the hydraulic pressure.

계속하여 유체가 나선유로를 지나면서 경사면을 가압하여 회전자를 회전시키는데, 유속 또는 유압의 잔여 파상 변동성분은 회전자의 회전관성에 대하여 파상적으로 경사면에 충격을 주고 이때 파상적 변동성분의 대부분이 운동에너지로 변환되면서 흡수되어 유속의 안정화를 얻을 수 있는 것이다.The fluid continues to pressurize the inclined surface as it passes through the spiral flow path, rotating the rotor. The residual wave fluctuations of the flow rate or hydraulic pressure impact the inclined planes with respect to the rotational inertia of the rotor. As it is converted into energy, it is absorbed to obtain stabilization of the flow rate.

이와 같이 본 고안은 입구측의 유속 또는 유압의 변동성분을 흡수 제거함으로써 소경목부에서 흐르는 유체의 유속분포를 균일하게 안정시키고 이로써 흡인작용의 원활화를 꾀할 수 있게 된 것이다.In this way, by absorbing and removing the variable component of the flow rate or the hydraulic pressure of the inlet side, it is possible to uniformly stabilize the flow rate distribution of the fluid flowing in the small diameter neck portion, thereby smoothing the suction action.
