Abstract
A kind of filter stainless steel A-frame process modification method, it is characterized in that：A-frame is when flatten the process of operation, using white glue with vinyl and silica flour 2：1 stirs, above-mentioned stirring glue is uniformly applied to the collapsed position of inside pipe wall before flattening, can so ensure substantial seamless inside collapsed position, during solving passivation procedure, wanted collapsed position penetrates into sour water, so as to cause the problem of collapsed position outwards seeps water after installing.The present invention utilizes adhesive curing rear enclosed flattening plane gap using in collapsed position spreading glue, it is ensured that oozed out filtering A-frame flattening end when room is installed without the water containing acid, it is to avoid influenceed because flattening the sour water oozed out at end and cartridge filter being produced using function.
Description
Technical field
The present invention relates to air filtering room technical field in gas turbine generating set, and in particular to a kind of filter is stainless
Steel A-frame process modification method.
Background technology
Air filtering room is one of part in gas turbine, and A-frame is cartridge filter in air filtering room
Important support part, conventional production craft step is as follows：Blanking, flattening, punching, bending, passivation.In the use process of product
In, when being frequently found product to in-site installation, the gap location that A-frame end is flattened has yellow rust water to ooze out, through analytical test
Sour water is penetrated into caused by body of rod inside by end crevice during for passivation, and the situation that this water containing acid oozes out can be to being propped up
The use of the cartridge filter of support and function have adverse effect on, it is therefore necessary to the production work of filter stainless steel A-frame
Process is improved.
The content of the invention
The problem of sour water being penetrated into present invention aim to address filter stainless steel A-frame tip-clearance, and propose
A kind of improvement of manufacturing technique method, it can solve A-frame because penetrating into unfavorable shadow of the sour water to the use function of cartridge filter
Ring.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of filter stainless steel A-frame process modification method, it is characterized in that：A-frame is carrying out flattening operation
Process when, using white glue with vinyl and silica flour 2：1 is stirred, and the above-mentioned glue stirred is applied to the pressure of inside pipe wall before flattening
Flat position, can so ensure to enrich seamless inside collapsed position, solve during passivation procedure, collapsed position to ooze
Enter sour water, so as to cause the problem of collapsed position is to extravasation sour water after installing.
The beneficial effects of the invention are as follows：The present invention is flattened using in collapsed position spreading glue using adhesive curing rear enclosed
Face gap, it is ensured that during acid wash passivation A-frame, flattens end without water of the infiltration containing acid, it is ensured that filtering triangle when room is installed
Support flattens end and oozed out without the water containing acid, it is to avoid produce influence to the use function of cartridge filter because flattening the sour water oozed out at end.
With reference to Figure of description, the present invention will be further described.
Brief description of the drawings
Fig. 1 is A-frame structural representation
Fig. 2 is that A-frame flattens end view
Embodiment
When A-frame flatten the process of operation, use a certain amount of white glue with vinyl with silica flour with 2：1 ratio is stirred
Mix uniform, before the tube end of A-frame is flattened, the above-mentioned white glue with vinyl stirred and silica flour are applied to tube end inwall
Collapsed position, while ensureing to enrich seamless inside collapsed position, tube end inwall collapsed position sealing feelings are checked after flattening
Condition, enters next step process after confirmation is intact, above-mentioned process modification is solved during passivation procedure, collapsed position to penetrate into
Sour water, so as to cause the problem of collapsed position outwards seeps water after installing.
