Abstract
The utility model discloses a dry gas seals filter core, including upper cover, lower cover and cylindric filter layer, upper cover and lower cover all are equipped with round ring groove, the filter layer includes first filtering layer, second filtering layer, inner frame and outer skeleton, first filtering layer, second filtering layer, inner frame and outer framework two ends through the roll welding setting in the recess. The utility model discloses a filter layer changes traditional adhesive bonded joint technology into roll welding to be connected, because the intensity that the roll welding is connected is higher than adhesive bonded joint's intensity far away, therefore there is not the condition of the damage equipment that comes unstuck in the filter layer, has stronger high temperature resistant, high -pressure ability, and the use operating mode is more extensive.
Description
Technical field
The utility model relates to filter element technical field, particularly a kind of dry gas seals filter core.
Background technology
Dry gas seals is that a kind of Novel shaft end fluting Sealing Technology being used for air seal seals, and belong to non-contact seals, dry gas seals filter core is the filter core utilizing this technology to realize sealing, the technical fields such as main application and compressor, filter and pumping system.The filter course of traditional dry gas seals filter core generally adopts adhesion process to be fixedly connected with the end cap at two ends, but because adhesion process is only firm, easily come unstuck under high temperature, high pressure, thus cause device damage, especially, when hermetic seal filter core is used for up to ten million expensive device, great economic loss can be caused.
Utility model content
For the problem that the filter course solving conventional dry hermetic seal filter core easily comes unstuck, the utility model discloses a kind of dry gas seals filter core, comprise upper cover, lower cover and cylindric filter course, described upper cover and lower cover are equipped with circle shape groove, described filter course comprises the first filtering layer, the second filtering layer, inner frame and purchasing ore, and described first filtering layer, the second filtering layer, inner frame and purchasing ore two ends are arranged in groove by roll welding.
As further improvement of the utility model, described first filtering layer is the metallic fiber sintered felt with catch net.
As further improvement of the utility model, described second filtering layer is cohesion fibrage.
As further improvement of the utility model, described inner frame is stainless steel rhombus net.
As further improvement of the utility model, described purchasing ore is corrosion resistant plate.
As further improvement of the utility model, described upper cover one end is provided with O RunddichtringO.
The beneficial effects of the utility model are:
Traditional gluing Joining Technology is changed into roll welding and connects by filter course of the present utility model, because the intensity of roll welding connection is far away higher than the intensity of gluing connection, therefore there is not the situation of the damage equipment that comes unstuck in filter course, and have stronger high temperature resistant, high pressure ability, applying working condition is more extensive.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Mark in figure: 1-upper cover; 2-lower cover; 3-filter course; 31-first filtering layer; 32-second filtering layer; 33-inner frame; 34-purchasing ore; 4-groove; 5-O RunddichtringO.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.
As shown in Figure 1, a kind of dry gas seals filter core, comprises upper cover 1, lower cover 2 and cylindric filter course 3, and upper cover 1 and lower cover 2 are equipped with circle shape groove 4, and upper cover one end is provided with O RunddichtringO 5.
As shown in Figure 2, filter course 3 is comprised the first filtering layer 31, second filtering layer 32, inner frame 33 and purchasing ore 34, first filtering layer 31, second filtering layer 32, inner frame 33 and purchasing ore 34 two ends and is arranged in groove 4 by roll welding.
Wherein, the first filtering layer 31 is the metallic fiber sintered felt with catch net; Second filtering layer 32 is cohesion fibrage; Inner frame 33 is stainless steel rhombus net; Purchasing ore 34 is corrosion resistant plate.
Traditional gluing Joining Technology is changed into roll welding and connects by filter course of the present utility model, because the intensity of roll welding connection is far away higher than the intensity of gluing connection, therefore there is not the situation of the damage equipment that comes unstuck in filter course, and have stronger high temperature resistant, high pressure ability, applying working condition is more extensive.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
