SEPARATION REMOVAL AND CIRCULATION SYSTEM OF AIR BUBBLES IN FLUID

摘要

A main air bubble separation apparatus which uses a swirling flow of oil introduced from a main tank separates the oil into a first oil with air bubbles removed therefrom, and a second oil containing air bubbles; a sub-air bubble separation apparatus is provided in which the second oil is introduced and then separated into a third oil with air bubbles removed therefrom and a fourth oil containing air bubbles; and a sub-tank into which the fourth oil is introduced, and in which the air bubbles contained in the fourth oil are captured and combined with each other so as to be removed from the fourth oil, so that a fifth oil is formed, and is configured such that the first, third and fifth oils are returned to the main tank.

1. A separation removal and circulation system of air bubbles in fluid comprising:
a main tank which stores fluid containing air bubbles to be removed therefrom; a first air bubble separation apparatus into which the fluid containing air bubbles to be removed therefrom is introduced to form a swirling flow of the fluid containing air bubbles to be removed therefrom, so that the fluid containing air bubbles to be removed therefrom is separated into a first fluid with air bubbles removed therefrom and a second fluid containing air bubbles; a second air bubble separation apparatus into which the second fluid separated in the first air bubble separation apparatus is introduced to form a swirling flow of the second fluid, so that the second fluid is separated into a third fluid with air bubbles removed therefrom and a fourth fluid containing air bubbles; and a sub-tank into which the fourth fluid is introduced so that air bubbles contained in the fourth fluid are captured and combined with each other so as to be removed from the fourth fluid, wherein the fluid stored in the main tank and containing air bubbles to be removed therefrom is supplied to the first air bubble separation apparatus via a first pipe; the first fluid separated in the first air bubble separation apparatus is returned to the main tank via a second pipe; the second fluid separated in the first air bubble separation apparatus is introduced into the second air bubble separation apparatus via a third pipe; the third fluid separated in the second air bubble separation apparatus is returned to the main tank via a fourth pipe; the fourth fluid separated in the second air bubble separation apparatus is introduced into the sub-tank via a fifth pipe; and a fifth fluid with air bubbles removed therefrom in the sub-tank is returned to the main tank via a sixth pipe.
