Description
Affiliated technical field
The present invention relates to a kind of vibration equipment noise is controlled and transform, prevent the technology that device structure vibration solid is propagated.
Background technique
Its main circulation way of vibration equipment noise is the construct noise that transmits through building structure with low-frequency vibration.The transfer of vibration of attenuation apparatus is to realize through eliminating being rigidly connected between them.The method of dealing with problems at present is that configuration is formed vibro-damping mount by rigid mass piece and vibration isolator between equipment and building structure.Because equipment is starting and dwell period, a certain stage of rotating speed in the change procedure of 0 ~ rated speed, the damping spring vibration isolator natural frequency situation consistent with the rotating equipment forcing frequency will inevitably appear, cause producing resonance phenomenon, vibration isolation was lost efficacy.Certain occasion to the exigent situation of equipment vibration isolation under, when a vibration isolation has been satisfied not vibration isolation and required, need to adopt two-stage vibration isolation.The two-stage vibration isolation structural vibrations is delivered in further decay on the basis of transfer of vibration of a vibration insulation structure, transmits than littler and vibration isolating effect is better thereby make.
The two-stage vibration isolation structure of using at present is a vibration insulation structure to be placed on another vibration insulation structure form.But exist following not enough: 1, the height of equipment vibro-damping mount doubles, and causes the equipment crank.2, two vibration insulation structure vibration isolator natural frequencys do not have the strictness selection of staggering, and still can produce resonance phenomenon.3, after equipment is provided with the two-stage vibration isolation structure; The resiliently deformable of vibrating isolation system can cause equipment start and level that dwell period can cause equipment to displacement; The equipment of delivery pressure such as water pump and blower fan particularly, equipment and connect the position and can be impacted and cause infringement.How the height of two-stage vibration isolation structure and don't raising equipment vibro-damping mount both had been set; Can eliminate resonance phenomenon effectively; Can control startup, dwell period displacement effectively again, still not have a kind of effective solution up to now and cause the two-stage vibration isolation structure to fail to apply.More at present use engineering work load is bigger, and the floating building structure ground of the machine room that expense is higher is provided with rigid mass piece and vibration isolator again and forms vibro-damping mount as the two-stage vibration isolation structure between equipment and floating building structure ground.
Summary of the invention
Be provided with in order to overcome equipment that the two-stage vibration isolation structure can produce that the equipment total height improves, the existence of resonance phenomenon and the deficiency of device start displacement; The object of the present invention is to provide a kind of equipment two-stage vibration isolation structure; Total height is low; Can eliminate resonance phenomenon, again the equipment vibro-damping mount of control apparatus startup effectively, dwell period displacement.
The technical solution adopted for the present invention to solve the technical problems is: the two-stage vibration isolation structure is set; Equipment is installed in by the upper support steel plate, upward the rigid mass piece reaches on the last vibration insulation structure of going up vibration isolator; Last vibration isolator is installed between the lower support steel plate of upper support steel plate and following vibration insulation structure; Between the following rigid mass piece and lower support steel plate of vibration insulation structure, following vibration isolator was installed in down between the middle Supporting Steel Plate and terrace of rigid mass piece under the rigid mass piece of last vibration insulation structure embedded.The vibration equipment bang path: equipment → go up rigid mass piece → go up vibration isolator → following rigid mass piece → following vibration isolator → terrace, form the tandem compound of two-stage vibration isolation, not only reach the purpose of two-stage vibration isolation but also effectively reduced the height of equipment vibro-damping mount.
The vibration isolator mounting point is provided with mounting hole on the upper support steel plate; Cover access panel above, establish the vibration isolator positioning hole in the middle of the access panel, the A nut is welded under the upper support steel plate; Access panel uses A bolt and fixed connection, and the lower support steel plate is provided with the vibration isolator setting sleeve.The B bolt on vibration isolator top is adjusted the balance of vibration insulation structure in the rotation.The C bolt on vibration isolator top is adjusted down the balance of vibration insulation structure under the rotation.The rigid mass piece is made up of steel frame and counterweight, and the structural rigidity of steel frame should satisfy the balanced requirement of transfer of vibration, and the material of balancing weight can use steel plate, ingot iron, heavy concrete etc. to be combined into required counterweight weight.
Distance in upper support steel plate and the following rigid mass piece between the Supporting Steel Plate should be greater than the maximum compression amount of deformation of last vibration isolator.Distance between lower support steel plate and the terrace should be greater than the maximum compression amount of deformation of following vibration isolator.Upper and lower vibration isolator is a plurality of, is symmetrical set along the bearing structure central shaft, to enlarge loaded area, improves the harmony of bearing load.Upper and lower vibration isolator uses the vibration isolator of two kinds of different natural frequencies; Because equipment is starting and dwell period; Rotating speed certain in the change procedure of 0 ~ rated speed forcing frequency of equipment in a flash is unique; It can not produce resonance with two kinds of different natural frequencies simultaneously, thereby eliminates resonance phenomenon effectively.
Be provided with around the vibration insulation structure by carrying the damping snubber that steel structure and rubber vibration insulating pad are formed, the rubber vibration insulating pad of damping snubber is parallel with the vertical facade of vibration insulation structure, between leave certain slit, vibrate through the transmission of damping snubber preventing.The damping snubber can be provided with between last vibration insulation structure and terrace, also can be provided with between vibration insulation structure and the terrace down, as being provided with between vibration insulation structure and the terrace down, between last vibration insulation structure and the following vibration insulation structure damping positioner should be set.The load scope of damping snubber is greater than the gross weight of equipment, vibration insulation structure and two-stage vibration isolation structure.
The invention has the beneficial effects as follows, reduce the two-stage vibration isolation structure height, control resonance and equipment offset phenomena reduce the transmission of device structure vibration solid effectively.
