Description
Technical Field
[0001] The utility model relates to the technical field of oil tank defoaming, in particular to a labyrinth-type defoaming oil tank. Background Art
[0002] In mechanical equipment, the oil tank, a critical component of the oil system, plays a crucial role. Fluctuations in internal system pressure and temperature, as well as mechanical agitation, often lead to the formation of bubbles in the oil. When these bubbles enter the oil system and rapidly burst, they release significant energy, potentially damaging critical components such as the pump, gears, piping, and seals. Furthermore, bubble formation increases oil temperature and accelerates oil oxidation, negatively impacting system performance and potentially shortening equipment life. Therefore, developing an efficient defoaming oil tank design is crucial.
[0003] Existing technologies, such as a Chinese patent, disclose a defoaming oil tank (application publication number CN 116771736 A). This technical solution reduces or eliminates bubbles in the oil by adding defoaming layers and defoaming barrels in the oil tank. However, this technical solution has the following disadvantages: the provision of multi-layer defoaming components makes the oil tank structure more complicated, which not only increases the cost, but also because the defoaming components are welded in the mailbox, they are affected by vibration, which increases the failure rate of the oil tank; secondly, the defoaming components are arranged in the oil tank, which makes it inconvenient to clean and maintain the oil tank.
