Problems solved by technology

The disadvantage here is that the air bubbles have a short residence time in the medium layer, reducing the possibility of air bubbles colliding and combining to form larger air bubbles

Embodiment Construction

[0076] figure 1 A schematic diagram of a separation element 10 according to an exemplary embodiment of the invention is shown during the separation of gas bubbles of different sizes present in a liquid. The separating element 10 is used to separate air bubbles from liquids such as hydraulic oil, lubricating oil, engine oil, etc. In the following description, the liquid is generally referred to as oil, and the air bubbles are generally referred to as air bubbles.

[0077] The separation element 10 is often used in combination with a filter device which, together with the tank, constitutes a tank filter system. This filter unit see Figure 5 with Figure 7 to Figure 10 , which will be discussed in detail later.

[0078] from figure 1 It can be seen that an approximately real air bubble distribution in a canister filter system of the type described above is displayed. Normally, when oil enters the tank, air bubbles separate from the oil. Said separating element 10 may be a...

Abstract

The invention relates to a separating element (10) for separating bubbles (11) from a liquid and in particular to a separating element (10) for separating bubbles (11) from hydraulic oil, the separating element comprising a volume body (12) with a perforated material structure (13), wherein the material structure (13) has a plurality of cells (14), the cells (14) are arranged offset from each other in such a way that the bubbles (11) are guided to travel in a labyrinth manner through a plurality of flow paths (15) of the material structure (13), wherein the material structure (13) comprises atleast one contact region (16) in which at least two flow paths (15) are at least partially close to each other, so that during operation, the bubbles (11) guided in the flow paths (15) are in contactwith each other and are thus combined to form larger bubbles (11'). The invention further relates to a separating unit, a filter element, a filter housing, a filter device, and a separating method.

Description

technical field [0001] The invention relates to a separating element, a separating unit, a filter element, a filter housing, a filter device and a method for separating air bubbles from a liquid. Background technique [0002] A filter system is generally considered to filter out solid particles in a liquid, such as hydraulic oil, lubricating oil or engine oil, thereby purifying the liquid. Well known filter systems for liquid filtration include in-line filters, suction filters and return filters. A well-known problem is that the oil contains air, which becomes trapped in the oil in the form of air bubbles. Due to the physical properties of air bubbles, they cannot be filtered out of the oil. The air bubbles flow through the filter element of the filter and are thus finely crushed and then mixed with the oil again. As the requirements for the purity of the liquid increase, the filter element must filter out smaller and smaller solid particles, so the filter material of the...
