Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of compressors, in particular to a multi-cylinder shared air intake buffer bracket. Background Art
[0002] When designing a large compressor unit, multiple cylinders are designed to share one intake buffer according to the gas volume requirements. At this time, due to space limitations, the intake buffer is not designed with a bracket. In the process of mechanical vibration calculation, it is found that with the reciprocating motion of the piston, the intake buffer resonates along the axial direction of the piston rod, and the resonance frequency is the third or fourth order of the compressor speed.
[0003] When the mechanical resonance of the air intake buffer is severe, the compressor will not work properly. When the buffer cylinder vibrates highly, fatigue damage to the container nozzle may occur. It may even cause high vibration of the branch pipeline and cause the branch pipeline to break.
[0004] Since the tensile force of the unit cannot be adjusted, an effective method is to add support to the air intake buffer so that the air intake buffer is no longer in a cantilever mode. The existing solution is to increase the radial support of the cylinder by welding baffles in the air intake buffer. However, welding baffles in the air intake buffer requires more complicated and tedious operations and is not conducive to subsequent maintenance. Therefore, it is urgent to develop an air intake buffer bracket that is easy to install and maintain. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a multi-cylinder shared intake buffer bracket, which solves the problem that during the operation of the existing reciprocating compressor, the reciprocating motion of the piston will bring a large tensile force, increase the vibration of the intake buffer, and in severe cases cause mechanical resonance of the intake buffer.
[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a multi-cylinder shared intake buffer bracket, including a number of base plates corresponding to the number of middle bodies, support columns are fixedly provided on the base plates, the upper ends of the support columns are fixedly connected to the cross beam, a pair of oblique support beams are provided on the cross beam, and a pipe clamp for clamping the intake buffer is provided at one end of the oblique support beam.
[0007] Preferably, the pipe clamp consists of an upper clamp body and a lower clamp body, and the upper clamp body and the lower clamp body are connected by bolts and nuts.
[0008] Preferably, welding connections are adopted between the base plate and the support column, between the support column and the cross beam, and between the cross beam and the oblique support beam.
[0009] Preferably, the number of the base plates is three.
[0010] Preferably, the number of the base plates is two.
[0011] Beneficial Effects
[0012] The utility model provides a multi-cylinder shared intake buffer bracket, which has the following beneficial effects:
[0013] The device has a simple structure, easy to purchase parts, low processing cost, and is easy to maintain. By adding two oblique support beams between the air intake buffer and the middle body, the axial rigidity of the piston rod is strengthened to resist the influence of the tensile force brought by the piston on the air intake buffer. It can also be used as a reserve solution and can be installed at any time on site according to the vibration conditions, which brings convenience to people's use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.
[0024] Example: Before adding the bracket, the air intake buffer is only connected to the cylinder through the outlet flange and is in a cantilever state. It will resonate under the influence of the piston movement. Therefore, after reserving the top plate on the top of the middle body, the buffer bracket of this article can be rooted on the top of the middle body through welding or bolting to achieve the purpose of supporting the air intake buffer, which can strengthen the axial rigidity of the piston rod and resist the influence of the piston movement. The specific installation process is as follows:
[0025] First, fix the three bottom plates 1 on the top of the three middle bodies, weld the three support columns 2 to the bottom plates 1, and then weld them to the cross beam 3. Install the pipe clamp 5 on the air intake buffer cylinder through bolts 6 and nuts 7. After adjusting the angle, use the inclined support beam 4 to weld the pipe clamp 5 to the cross beam 3 to complete the installation. The above is a buffer bracket shared by three cylinders. At the same time, the present application is also applicable to compressor units with dual-cylinder shared air intake buffers. The bracket in this article can be used as a method to solve the buffer resonance in the compressor design stage, and can also be used to deal with the vibration problem of the air intake buffer on site.
