Description
Technical field
The present invention relates to a kind of Noise and Vibration Control device, especially prevent the mechanical floor pipeline vibration insulation structure that pipe vibration solid is propagated.
Background technique
The fluid delivery pipeline of equipment is the important component part of device systems, as the good conductor of mechanical vibration, can make device systems vibration along the long-range propagation of pipeline.Particularly the variation of the medium runnability in pipeline can make section of tubing produce more serious seismism, strong pipe vibration can make pipeline fittings particularly the connected element of pipeline occur loosening.Under the effect of fluid excitation 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 pipeline played to yielding support effect, and vibration has good isolation and the significantly effect of reduction construct noise to Management of Pipeline Mechanical Equipment.But in the high place of separating vibration noise requirements, 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 to the vibration isolation of pump equipment, require very high, 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 completely separated with building structure, if vibration isolation only with elastic bearing component, is difficult to reach the requirement of hotel guest-room to ambient noise.
Certain occasion to the exigent situation of vibratory equipment vibration isolation under, when a vibration isolation can not meet vibration isolation requirement, need to adopt two-stage vibration isolation.Known conditions and the definite kinetic parameter of Vibration Absorbing System Design of the kinetic parameter design of a vibration insulation structure are the known conditions that two-stage vibration isolation designs.The vibration of two-stage vibration isolation structure is delivered in further decay on the basis that the vibration of a vibration insulation structure transmits, thereby makes to transmit 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, rubber parts is set as vibration isolator, utilizes the damping isolation effect of rubber parts, intercepts the Vibration propagation of pipeline.Under general occasion, can meet the vibration isolation requirement of pipeline.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 the impact of mechanical floor pipeline is mainly pipe vibration is propagated, take low frequency as main.
Summary of the invention
In order to overcome existing vibration isolator for pipe clamp of pipeline, the solid structure of mechanical floor pipe vibration is propagated to the deficiency of controlling, the invention provides a kind of mechanical floor pipeline vibration insulation structure, this mechanical floor pipeline vibration insulation structure can not only effectively be controlled the solid structure of pipe vibration and propagate, and vibration isolation efficiency is high.And can adjust as required the height of vibration insulation structure, guarantee 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 comprised of the lower vibration insulation structure that is arranged on the pipeline partiting polarization component under pipeline and be arranged between pipeline partiting polarization component and terrace.Pipeline partiting polarization component is comprised of pipe-supporting frame, elasticity absorbing pad and upper adjustable spring vibration isolator, the integral type 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 comprised of vibration isolation mass block, support steel structure, lower adjustable spring vibration isolator and rubber damper, the integral type member that vibration isolation mass block is formed by steel plate framework structure, counterweight.Spring vibration isolation utensil has static deflection large, and natural frequency is low, and the feature that low frequency vibration isolation performance is good can prevent low-frequency vibration short circuit.Rubber vibration insulating pad has the advantages that high-frequency vibration isolation performance is good, can prevent dither short circuit.Pipeline partiting polarization component and the lower vibration insulation structure being arranged under pipeline partiting polarization component form two-stage vibration isolation structure, thereby have guaranteed the iris action to pipe vibration.
Described pipe-supporting frame is arranged on below pipeline, and elasticity absorbing pad is set 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.Support steel structure welding is at steel plate framework texture edge, and lower adjustable spring vibration isolator is arranged under support steel structure, between lower adjustable spring vibration isolator and terrace, rubber damper is set.Described counterweight can whole installation under pipeline, also can be separately positioned on two limits under pipeline, by steel plate framework structure, form integral type vibration isolation mass block, counterweight is used the hyperbaric materials such as steel plate, ingot iron, heavy concrete.If the space under pipeline is inadequate, integrated type counterweight can not be set, under pipeline, two limits arrange counterweight, by steel plate framework structure, form integral type vibration isolation mass block, also can meet the use function of vibration isolation mass block.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 is used hyperbaric material as far as possible.Upper adjustable spring vibration isolator can be a plurality of, along pipe-supporting frame central shaft, is symmetrical arranged; Lower adjustable spring vibration isolator can be a plurality of, along vibration isolation mass block central shaft, is symmetrical arranged.To expand loaded area, improve the harmony of bearing load.The bolt on rotary adjustable spring vibration isolation device top is adjusted balance and the level height of pipeline partiting polarization component, lower vibration insulation structure.Because mechanical floor relevant device, pipeline are numerous, both be connected to each other and separately bearing load be not quite similar, after mechanical floor pipeline vibration insulation structure is set, when compress variation during due to each adjustable spring vibration isolator bearing load is inconsistent, can cause relevant device, the pipe level discrepancy in elevation.If there is no the adjustment function of level height, the interface discontinuity equalization of equipment, pipeline enclosure, can there is loosening damage in connected element.
The invention has the beneficial effects as follows, can effectively control the solid structure of pipe vibration and propagate, vibration isolation efficiency is high.And can adjust as required the height of vibration insulation structure, guarantee the load balance of relevant device, pipeline.
