In general, the oil applied to the hydraulic system of the vehicle, as shown in Figure 2, while passing through the hydraulic system 101 will include air bubbles 103 to rot with the air in the oil pipe, air bubbles 103 as described above Oil (100) is supplied to the oil tank 107 via the recovery tank 105, from the oil tank 107 is supplied to the hydraulic system 101 of the vehicle.

상기와 같이, 공기방울(103)을 포함하는 오일(100)이 유압시스템(101)에 적용되는 경우에는 유압 작동시 상기 공기방울(103)의 체적만큼 밀림 현상이 발생하여 정밀한 유압시스템(101)의 작동을 이룰 수 없게 된다. As described above, when the oil 100 including the air bubbles 103 is applied to the hydraulic system 101, a push phenomenon occurs by the volume of the air bubbles 103 during the hydraulic operation, so that the precise hydraulic system 101 is applied. Will not work.

따라서 종래에는 상기 유압시스템용 오일(100)에 포함된 공기방울(103)을 제거하기 위하여 순수오일을 공급하면서 동시에 공기방울(103)이 포함된 오일(100)을 빼내는 에어빼기작업을 수시로 수행해야 하는 등의 불편함이 있었다. Therefore, in the related art, in order to remove the air bubbles 103 included in the oil for the hydraulic system 100, at the same time supplying pure oil, at the same time air draining operation to remove the oil 100 containing the air bubbles 103 must be performed. There was an inconvenience, such as.

이러한 불편함을 해소하기 위하여, 최근에는 상기 오일탱크(107)의 상부에 진공펌프(109)와 연결되는 부압관(111)을 연결하여 오일탱크(107) 내부에 부압을 형성함으로써, 충진된 오일 내의 공기방울(103)을 외부로 빨아내도록 하는 에어제거장치를 구성하여 사용하고 있다.In order to alleviate this inconvenience, in recent years by connecting the negative pressure pipe 111 connected to the vacuum pump 109 to the upper portion of the oil tank 107 to form a negative pressure inside the oil tank 107, the oil filled The air removal device which sucks the air bubble 103 inside to an outside is comprised and used.

그러나 상기한 바와 같이 종래의 에어제거장치를 이용하여 오일탱크의 내부에 부압을 형성하여 공기방울을 외부로 빨아내는 방법은 오일의 유면 상부에 부상되어 있는 공기방울만 제거할 수 있을 뿐, 오일 속에 분포되어 있는 미세한 공기방울은 제거가 불가능하다는 문제점을 내포하고 있다.However, as described above, a method of sucking negative air bubbles by forming a negative pressure inside the oil tank by using a conventional air removing device can remove only air bubbles floating on the oil surface, and in the oil Distributed fine air bubbles have a problem that it is impossible to remove.

따라서, 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 창출된 것으로서, 본 발명의 목적은 초음파을 이용하여 오일을 진동시킴으로써 오일 내에 포함된 미세한 공기방울이 서로 엉겨서 부상되도록 하여 부압에 의해 제거가 용이하도록 하는 오일탱크의 에어제거장치에 관한 것이다. Therefore, the present invention was created to solve the problems as described above, an object of the present invention is to vibrate the oil using ultrasonic waves so that the fine air bubbles contained in the oil entangled with each other to be easily removed by the negative pressure. It relates to an air removing device of the oil tank.

상기한 바와 같은 목적을 달성하기 위하여 본 발명에 따른 오일탱크의 에어제거장치는 차량의 유압시스템으로부터 회수탱크를 거쳐 오일탱크에 저장된 후, 다시 유압시스템으로 공급되는 오일 내에 공기방울을 제거하기 위하여 상기 오일탱크의 상부 일측에 연결되는 부압관과, 상기 부압관을 통하여 오일탱크 내부에 부압을 형성하는 진공펌프로 구성되는 오일탱크의 에어제거장치에서,In order to achieve the object as described above, the air removing device of the oil tank according to the present invention is stored in the oil tank through the recovery tank from the hydraulic system of the vehicle, and then to remove the air bubbles in the oil supplied to the hydraulic system again In the air tank removing device of the oil tank consisting of a negative pressure pipe connected to the upper side of the oil tank, and a vacuum pump to form a negative pressure inside the oil tank through the negative pressure pipe,

상기 오일탱크의 하부 바닥면에는 제어기의 제어신호에 따라 설정대역의 초음파를 발생시키는 초음파 발생수단을 더 포함하는 것을 특징으로 한다.The lower bottom surface of the oil tank is characterized in that it further comprises an ultrasonic wave generating means for generating ultrasonic waves of the set band in accordance with the control signal of the controller.

이하, 첨부 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 실시예에 따른 오일탱크의 에어제거장치의 구성도이다.1 is a block diagram of an air removal apparatus of an oil tank according to an embodiment of the present invention.

본 발명은 오일(1)이 차량의 유압시스템(3)에 적용되어 공기방울(5)을 포함한 상태로 회수탱크(7)를 거쳐 오일탱크(9)에 저장된 후, 오일탱크(9)에서 공기방울(5)을 완전히 제거하여 다시 차량의 유압시스템(3)으로 다시 공급될 때, 공기방울(5)을 포함하지 않은 오일이 유압시스템(3)에 공급되도록 하여 정밀한 유압시스템(3)의 작동을 이룰 수 있도록 하기 위한 것이다. According to the present invention, after the oil 1 is applied to the hydraulic system 3 of the vehicle and stored in the oil tank 9 via the recovery tank 7 with the air bubbles 5 included therein, the air in the oil tank 9 When the droplets 5 are completely removed and supplied again to the hydraulic system 3 of the vehicle, oil not including the air bubbles 5 is supplied to the hydraulic system 3 so that the precise hydraulic system 3 is operated. To achieve this.

이러한 본 발명의 구성은 상기 오일탱크(9)의 상부 일측에 부압관(11)을 설치하고, 상기 부압관(11)은 진공펌프(13)와 연결된다. The configuration of the present invention is provided with a negative pressure pipe 11 on the upper side of the oil tank 9, the negative pressure pipe 11 is connected to the vacuum pump (13).

그리고 상기 오일탱크(9)의 하부 바닥면에는 제어기(15)의 제어신호에 따라 설정대역의 초음파(S)를 발생시키는 초음파 발생수단인 초음파 발진기(17)를 설치한다. In addition, an ultrasonic oscillator 17, which is an ultrasonic wave generating means for generating ultrasonic waves S of a set band, is installed on the lower bottom surface of the oil tank 9 according to a control signal of the controller 15.

상기 초음파 발진기(17)는 그 진동판(19)이 상기 오일탱크(9)에 충진된 오일(1)에 최대한 노출되도록 오일탱크(9)의 바닥면 상에서 돌출되어 장착되며, 상기 진동판(19)은 티타늄 재질로 이루어지는 것이 바람직하다. The ultrasonic oscillator 17 is mounted to protrude on the bottom surface of the oil tank 9 so that the diaphragm 19 is exposed to the oil 1 filled in the oil tank 9 as much as possible, and the diaphragm 19 is It is preferably made of titanium.

따라서 상기한 바와 같이 구성되는 오일탱크의 에어제거장치의 작동은 상기 오일이 유압시스템(3)을 통과하면서 오일 배관 내의 공기와 썩여 공기방울(5)을 포함하여 회수탱크(7)를 거쳐 오일탱크(9)로 공급된다. Therefore, the operation of the air removing device of the oil tank configured as described above is the oil tank through the recovery tank (7), including the air bubbles (5) rotting with the air in the oil pipe while passing through the hydraulic system (3) It is supplied to (9).

이 때, 상기 오일탱크(9) 내부에는 부압관(11)으로 연결된 진공펌프(13)에 의해 부압이 형성되고, 제어기(15)는 상기 초음파 발진기(17)를 작동시켜 진동판(19)을 통하여 오일탱크(9) 내에 충진된 오일(1)에 초음파(S)를 방출하여 진동을 발생시키게 된다. At this time, a negative pressure is formed in the oil tank 9 by a vacuum pump 13 connected to the negative pressure pipe 11, and the controller 15 operates the ultrasonic oscillator 17 through the diaphragm 19. Ultrasonic waves S are emitted to the oil 1 filled in the oil tank 9 to generate vibrations.

이에 따라, 상기 오일(1) 내에 포함된 미세한 공기방울(5)은 서로 엉겨서 유면(21) 상부로 부상하게 되며, 유면(21) 상부로 부상한 공기방울(5)은 상기 진공펌프(13)에 의해 오일탱크(9) 내부에 형성된 부압에 의해 외부로 빨아내어져 제거되는 것이다. Accordingly, the fine air bubbles 5 contained in the oil 1 are entangled with each other to rise above the oil surface 21, and the air bubbles 5 floating above the oil surface 21 are the vacuum pump 13. By being sucked to the outside by the negative pressure formed inside the oil tank (9) is removed.

즉, 초음파(S)을 이용하여 오일(1)을 진동시킴으로써 오일(1)의 유면상에 존재하는 공기방울(5)뿐만 아니라 오일(1) 속에 포함된 미세한 공기방울(5)도 서로 엉겨서 부상되도록 하여 부압에 의해 완전제거가 가능하게 되는 것이다. That is, by vibrating the oil 1 using the ultrasonic wave S, not only the air bubbles 5 present on the oil surface of the oil 1 but also the fine air bubbles 5 contained in the oil 1 are entangled with each other. It is possible to be completely removed by the negative pressure to be floating.

상술한 바와 같이 본 발명에 따른 오일탱크의 에어제거장치에 의하면, 초음파을 이용하여 오일을 진동시켜 오일 내에 포함된 미세한 공기방울이 서로 엉겨서 부상되도록 함으로써, 부압에 의해 완전히 제거할 수 있어 차량의 유압시스템의 정밀한 작동을 가능하게 하는 효과가 있다.As described above, according to the air removing device of the oil tank according to the present invention, by vibrating the oil using ultrasonic waves so that fine air bubbles contained in the oil are entangled with each other, they can be completely removed by the negative pressure so that the hydraulic system of the vehicle Has the effect of enabling precise operation of
