Description
Technical field
The present invention relates to a kind of Noise and Vibration Control device, the mechanical floor pipeline vibration insulation structure especially preventing pipe vibration solid from propagating.
Background technique
The fluid delivery pipeline of equipment is the important component part of device systems, as the good conductor of mechanical vibration, device systems can be made to vibrate along the long-range propagation of pipeline.The change of the medium runnability particularly in pipeline can make section of tubing create more serious seismism, strong pipe vibration can make pipeline fittings particularly pipeline connected element occur loosen.Under the effect of fluid exciting force, pipeline self also can produce vibration or even intense impact.Be generally used for being equipped with on the pipeline of flexibly mounted machinery, not only yielding support effect played to pipeline, and to Management of Pipeline Mechanical Equipment vibration, there is good isolation and significantly reduce the effect of construct noise.But in the place that separating vibration noise requirements is high, the vibration isolating effect of elastic bearing component just can not meet the demands.Particularly at the water pump of air conditioner mechanical floor in high-rise hotel, very direct on the impact of following floor vibration noise.Not only require very high to the vibration isolation of pump equipment, and, also very responsive to the Vibration propagation of pipeline, particularly pump equipment and relevant device in mechanical floor, pipeline are numerous, be difficult to be separated completely with building structure, if vibration isolation is only with elastic bearing component, be difficult to reach the requirement of hotel guest-room to ambient noise.
In certain occasion in the exigent situation of vibratory equipment vibration isolation, when a vibration isolation can not meet vibration isolation requirement, need to adopt two-stage vibration isolation.The kinetic parameter that the known conditions of the kinetic parameter design of a vibration insulation structure and Vibration Absorbing System Design are determined is the known conditions of two-stage vibration isolation design.The vibration passing of two-stage vibration isolation structure is decayed further on the basis of the vibration passing of a vibration insulation structure, thus makes transmission than less and vibration isolating effect is better.
ZL200820156003.4 discloses a kind of vibration isolator for pipe clamp of pipeline, wherein between pipeline and upper and lower sheet metal, arranges rubber parts as vibration isolator, utilizes the damping isolation effect of rubber parts, intercepts the Vibration propagation of pipeline.The vibration isolation requirement of pipeline can be met under general occasion.The major advantage of rubber damper is the obstruct with high-frequency structure vibration, and shock resistance and sound insulation property, can meet the requirement of Rigidity and strength.The Young's modulus of rubber damper is very little, is a kind of nonlinear elastic material.So the natural frequency of rubber damper is higher, the damping efficiency of low frequency configuration noise is lower.And the solid structure that mechanical floor pipeline affects mainly pipe vibration is propagated, based on low frequency.
Summary of the invention
In order to overcome the deficiency of existing vibration isolator for pipe clamp of pipeline to the solid structure transmission controe of mechanical floor pipe vibration, the invention provides a kind of mechanical floor pipeline vibration insulation structure, the solid structure that this mechanical floor pipeline vibration insulation structure can not only control pipe vibration is effectively propagated, and vibration isolation efficiency is high.And the height of vibration insulation structure can be adjusted as required, ensure the load balance of relevant device, pipeline.
The technical solution adopted for the present invention to solve the technical problems is: a kind of mechanical floor pipeline vibration insulation structure, is made up of the pipeline partiting polarization component be arranged under pipeline and the lower vibration insulation structure be arranged between pipeline partiting polarization component and terrace.Pipeline partiting polarization component is made up of pipe-supporting frame, elasticity absorbing pad and upper adjustable spring vibration isolator, the one-piece member that pipe-supporting frame is welded into by curved plate, two side force-bearing steel plates and stiffened plate; Lower vibration insulation structure is made up of vibration isolation mass block, supporting steel structure, lower adjustable spring vibration isolator and rubber damper, the one-piece member that vibration isolation mass block is formed by steel plate framework structure, counterweight.It is large that spring vibration-isolator has static deflection, and natural frequency is low, the feature that low frequency vibration isolation performance is good, can prevent low-frequency vibration short circuit.Rubber vibration insulating pad has the good feature of high-frequency vibration isolation performance, can prevent dither short circuit.Pipeline partiting polarization component and the lower vibration insulation structure under being arranged on pipeline partiting polarization component form two-stage vibration isolation structure, thus ensure that the iris action to pipe vibration.
Described pipe-supporting frame is arranged on below pipeline, and arranges elasticity absorbing pad between pipeline.Upper adjustable spring vibration isolator is arranged between the force-bearing steel plate of pipe-supporting frame and the steel plate framework structure of lower vibration insulation structure.Supporting steel structure is welded on steel plate framework texture edge, under lower adjustable spring vibration isolator is arranged on supporting steel structure, arranges rubber damper between lower adjustable spring vibration isolator and terrace.Under described counterweight is integrally provided in pipeline or be separately positioned on two limits under pipeline, form integral type vibration isolation mass block by steel plate framework structure, counterweight uses steel plate or ingot iron or the concrete high specific gravity material of heavy.If the space under pipeline is inadequate, can not arrange integrated type counterweight, under pipeline, two limits arrange counterweight, form integral type vibration isolation mass block, also can meet the using function of vibration isolation mass block by steel plate framework structure.Under square one, the quality of vibration isolation mass block is larger, and better, due to limited space in machine room, the volume of vibration isolation mass block is restricted vibration isolating effect, so the material of counterweight uses hyperbaric material as far as possible.Upper adjustable spring vibration isolator is multiple, is symmetrical arranged along pipe-supporting frame central shaft; Lower adjustable spring vibration isolator is multiple, is symmetrical arranged along vibration isolation mass block central shaft.To expand loaded area, improve the harmony of bearing load.The bolt on rotary adjustable spring vibration-isolator top adjusts pipeline partiting polarization component, the balance of lower vibration insulation structure and level height.Because mechanical floor relevant device, pipeline are numerous, both be connected to each other and respective bearing load is not quite similar, after mechanical floor pipeline vibration insulation structure is set, due to compress variation during each adjustable spring vibration isolator bearing load inconsistent time, relevant device, the pipe level discrepancy in elevation can be caused.If do not have the adjustment function of level height, the interface discontinuity equalization of equipment, pipeline enclosure, connected element can occur to loosen damage.
The invention has the beneficial effects as follows, the solid structure that effectively can control pipe vibration is propagated, and vibration isolation efficiency is high.And the height of vibration insulation structure can be adjusted as required, ensure the load balance of relevant device, pipeline.
