Embodiment Construction

[0008] The upper frame involved in this technical solution adopts an integrated structure instead of a general-purpose split structure, adopts a small flow resistance skeleton row type instead of the original hole row method, and adopts large filter area corrugated molding instead of the original corrugated molding technology, so In the same installation space, the filter element can have a larger dirt-holding capacity, and the flow resistance of the skeleton can be reduced under the premise of ensuring the strength of the skeleton.

[0009] Specific examples figure 1 As shown, the upper end cover skeleton 1, the filter layer 6 and the lower end cover 3 are connected to each other by high temperature glue curing, the upper end cover and the skeleton are integrated, and the filter layer spiral groove is processed at the place where the filter layer is installed along the skeleton axis of the upper end cover 4. There are flow holes 5 evenly drilled in the spiral groove along the...

Abstract

The invention discloses a filter element with a high dirt-holding capacity structure. The upper end cover skeleton, the filter layer and the lower end cover are connected together by high temperature glue curing, and the filter layer spiral groove is processed along the axis of the upper end cover skeleton where the filter layer is installed. And in the spiral groove uniformly drilled along the circumferential direction with liquid flow holes. The upper end cover and the skeleton are integrated, which provides a larger filter area for the filter element. The new corrugated molding technology is adopted to make the filter area larger under the same installation space. Under the same installation space and working environment conditions, the filter element of this structure can Compared with the ordinary structure of the filter element, the dirt holding capacity is higher and the service time is longer.

Description

technical field [0001] The invention relates to a filter element with a novel high dirt-holding capacity structure, which belongs to the field of hydraulic filtration and is used for filtering the working medium of a compact hydraulic system. Background technique [0002] At present, the filter elements commonly used in domestic and foreign hydraulic systems are glass fiber paper glued filter elements, which have the characteristics of short processing cycle, high filtration efficiency and long service life. Paper filter elements are consumable hydraulic components and cannot be reused. In order to ensure the normal operation of the hydraulic system, the filter element should be replaced in time after it expires. Therefore, the service life of the filter element directly affects the maintenance cycle of the hydraulic system. The main factors affecting the service life of the filter element are: the pollution degree of the working medium of the hydraulic system and the dirt...
