A method for installing fins of a water separator without welding

Abstract

The present invention provides a method for installing fins of a water separator without welding, which is used to install fins for separating gas and water from compressed gas to the air outlet of a cooler. First, a number of support plates, a number of fins and two fixing tools with the same appearance are provided. Installation holes are cut in the support plates. The support plates are divided into two types, A and B, according to the cutting positions of the installation holes. The support plates A and B are alternately installed on the fixing tools. By applying force to the support plates A and B, the positions of the installation holes on the two are aligned. Then the fins are inserted into the installation holes. After removing the applied force, the fins are fixed to the support plates. The whole composed of the support plates, the fins and the fixing tools is installed at the air outlet of the cooler to complete the overall installation. There is no need to weld the fins and perform post-treatment of the welds, thus achieving the effect of fixing the fins, thereby reducing the manufacturing cost, with a simple process and relatively convenient installation; the precision requirements for the fins and the installation holes of the support plates are relatively low.

Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and particularly relates to a method for installing fins of a water separator without welding. Background Art

[0002] In the multi-stage centrifugal compressor industry, after the compressed gas is cooled by a cooler, condensed water will be precipitated. It often happens that the condensed water is blown away by the high-pressure gas and carried to the next stage of compression, which will increase the energy consumption of the compressor and pose a potential safety hazard to the safe operation of the compressor. Generally, excess water droplets and fog can be filtered by adding fins to the water separator.

[0003] The existing demisting fins are generally fixed in the following two ways. In the first way, through holes corresponding to the shape of the fins are formed on the support plate, and the fins are inserted into the through holes to limit the movement of the fins. In this way, the fins are likely to become loose when the fitting tolerance between the fins and the through holes is relatively large; if the fitting tolerance between the fins and the through holes is relatively small, on the one hand, higher precision requirements are imposed on the fins and the through holes, and on the other hand, it brings difficulties to the installation. In the second way, the fins are fixed to the support plate by welding. This method has high requirements for the weld seam, and after welding, the weld seam also needs to be pickled and passivated, resulting in high costs.

[0004] In summary, it is necessary to propose a fin installation method with low cost, low installation difficulty and no need for welding. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for installing fins of a water separator without welding to solve the problems.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A method for installing fins of a water separator without welding, which is used to install fins for separating gas and water from the compressed gas to the air outlet of the cooler, is characterized in that it includes the following specific steps:

[0008] S1. Provide at least one first support plate, at least one second support plate, several fins and two fixing tools;

[0009] S2. Cut several first installation holes on the first support plate and several second installation holes on the second support plate, so that the projections of the nth first installation hole and the nth second installation hole in the plane where the first support plate or the second support plate is located are the same in size, the same in shape and staggered in position;

[0010] S3. Install the first support plate and the second support plate between the two fixing tools, and the first support plate and the second support plate are alternately arranged along the up and down directions of the fixing tools;

[0011] S4. Apply forces to the first support plate and the second support plate so that the nth first mounting hole of the first support plate corresponds to the position of the nth second mounting hole of the second support plate;

[0012] S5. Pass the fins one by one through the first mounting holes of the first support plate and the second mounting holes of the second support plate;

[0013] S6. Remove the forces applied to the first support plate and the second support plate. The nth first mounting hole and the nth second mounting hole tend to stagger from each other and apply forces to the fins respectively to fix the fins.

[0014] Further, in S6, the force applied to the fin by the nth first mounting hole is opposite to the force applied to the fin by the nth second mounting hole.

[0015] Further, the numbers of the first support plate and the second support plate are the same.

[0016] Further, the installation method further includes step S7 after step S6: Install the whole composed of the first support plate, the second support plate, several fins and two fixing jigs at the air outlet of the cooler.

[0017] Further, the fixing jig has several clamping grooves arranged in the vertical direction. In step S3, installing the first support plate and the second support plate between the two fixing jigs means clamping the two end parts of the first support plate / second support plate in the clamping grooves corresponding to the positions of the two fixing jigs respectively.

[0018] Further, the fixing jig further has operation holes connected to the clamping grooves in one-to-one correspondence. In step S4, applying forces to the first support plate and the second support plate means applying forces to the first support plate / second support plate through the operation holes.

[0019] The beneficial effects of the present invention are as follows: The water separation fin installation method of the present invention can achieve the effect of fixing the fins without welding the fins and post-processing the welds, thus reducing the manufacturing cost, having a simple process and being relatively convenient to install; and has relatively low precision requirements for the fins and the mounting holes of the support plates.

[0024] The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] In the description of the present invention, it should be noted that the terms "first" and "second" are used for descriptive purposes only and cannot be construed as indicating or implying relative importance. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Embodiment

[0027] Referring to the attached Figure 1 , the method for installing the fins of the water separator without welding in this embodiment is used to install the fins for separating gas and water from the compressed gas to the air outlet of the cooler, and includes the following specific steps:

[0028] S1. Provide at least one first support plate 1, at least one second support plate 2, several fins and two fixing toolings 3.

[0029] The first support plate 1 and the second support plate 2 are the same in quantity, shape and size. The fixing tooling 3 has several clamping grooves 31 arranged in the vertical direction and operation openings 32 connected to the clamping grooves 31 in one-to-one correspondence.

[0030] The quantity of the fins, the first support plate 1 and the second support plate 2 is selected according to the size of the air outlet of the cooler and the supporting strength of the fins. The number of the clamping grooves 31 on one fixing tooling 3 should be at least equal to the total number of the first support plate 1 and the second support plate 2, and the number of the operation openings 32 is the same as the number of the clamping grooves 31. The interval between the clamping grooves 31 can also be adjusted according to actual needs. The schematic structural diagram of the fixing tooling 3 can be referred to the attached Figure 3 .

[0031] S2. Cut a number of first mounting holes 11 in the first support plate 1 and a number of second mounting holes 21 in the second support plate 2, so that the projections of the nth first mounting hole 11 and the nth second mounting hole 21 in the plane where the first support plate 1 or the second support plate 2 is located are the same in size, the same in shape and staggered in position. Refer to the attached Figure 2 .

[0032] The cutting can be laser cutting or manual cutting, as long as the shapes and sizes of the first mounting holes 11 and the second mounting holes 21 are the same.

[0033] In addition to the shape and size, the number of the first mounting holes 11 is also the same as that of the second mounting holes 21. The first mounting holes 11 / second mounting holes 21 are evenly distributed on the first support plate 1 / second support plate 2. Stack the first mounting plate and the second mounting plate in alignment. The positions of the first mounting holes 11 are partially or completely staggered compared with the positions of the second mounting holes 21, that is, the nth first mounting hole 11 and the nth second mounting hole 21 cannot be completely aligned in the vertical direction.

[0034] S3. Install the first support plate 1 and the second support plate 2 between two fixing jigs 3, and the first support plate 1 and the second support plate 2 are alternately arranged along the vertical direction of the fixing jig 3.

[0035] Specifically, respectively clamp the two end parts of the first support plate 1 / second support plate 2 in the clamping grooves 31 corresponding to the positions of the two fixing jigs 3.

[0036] S4. Apply a force to the first support plate 1 and the second support plate 2 so that the nth first mounting hole 11 of the first support plate 1 and the nth second mounting hole 21 of the second support plate 2 are in corresponding positions.

[0037] The act of applying a force to the first support plate 1 / second support plate 2 is carried out by an operating member 32. This method should also provide a number of operating parts. The number of operating parts pass through the operating members 32 of the two fixing jigs 3 one by one, extend to the clamping grooves 31, and abut against the end parts of the first support plate 1 / second support plate 2. Apply force to the first support plate 1 / second support plate 2 from both ends simultaneously with the operating parts, and apply force to all the first support plates 1 and second support plates 2 simultaneously. The first support plate 1 and the second support plate 2 are deformed by the force, so that the nth first mounting hole 11 and the nth second mounting hole 21 are completely aligned in the vertical direction. Due to the cutting tolerances of the first mounting holes 11 and the second mounting holes 21 and the forces applied to each first support plate 1 / second support plate 2 cannot be completely the same, the so-called complete alignment here is basic alignment, so that the fins can smoothly pass through the first mounting holes 11 and the second mounting holes 21 along a straight line.

[0038] This embodiment provides a specific structure of an operating member 32 and an operating element. The operating member 32 is a threaded hole with an internal thread structure, and the operating element is a bolt detachably arranged in the operating member 32. The bolt is screwed in or out to apply or remove force to the first support plate 1 / the second support plate 2. The operating member 32 and the operating element may also be other structures in the prior art that can cooperate to achieve the application or removal of force to the first support plate 1 / the second support plate 2, and this embodiment does not make any specific restrictions.

[0039] S5, passing the fins through the first mounting holes 11 of the first support plate 1 and the second mounting holes 21 of the second support plate 2 one by one.

[0040] S6. Remove the force applied to the first support plate 1 and the second support plate 2. The nth first mounting hole 11 and the nth second mounting hole 21 have a tendency to stagger with each other and apply force to the fins respectively to fix the fins.

[0041] The first support plate 1 and the second support plate 2 return to their original state after losing the external force, so that the first mounting hole 11 and the second mounting hole 21 have a tendency to be offset from each other to reset, and the two tendencies are opposite, so the force applied by the nth first mounting hole 11 to the fin is opposite in direction to the force applied by the nth second mounting hole 21 to the fin, and these two opposite forces cause the fin to deform slightly, thereby achieving the fixation of the fin. After fixation, the deformation of the fin is not very obvious visually, so the first mounting hole 11 and the second mounting hole 21 are aligned visually. Under the premise that the number of the first support plate 1 and the second support plate 2 is the same and the number is two or more, the fin is more stable. The purpose of having the same number of the first support plate 1 and the second support plate 2 is to balance the force on the fin.

[0042] S7, installing the whole consisting of the first support plate 1, the second support plate 2, a plurality of fins and two fixing fixtures 3 at the air outlet of the cooler.

[0043] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
