Description
Technical field
The present invention relates to a kind of vibration equipment noise be controlled to transformation, prevent the technology that device structure vibration solid is propagated.
Background technique
Its main circulation way of vibration equipment noise is the construct noise transmitting by building structure with low-frequency vibration.The vibration transmission of attenuation apparatus is to realize by eliminating being rigidly connected between them.The method of dealing with problems is at present that configuration forms vibro-damping mount by rigid block and vibration isolator between equipment and building structure.Because equipment is starting and dwell period,, will inevitably there is the situation that damping spring vibration isolator natural frequency is consistent with rotating equipment forcing frequency in rotating speed certain one-phase in the change procedure of 0 ~ rated speed, cause producing resonance phenomenon, and vibration isolation was lost efficacy.Certain occasion to the exigent situation of equipment vibration isolation under, when a vibration isolation can not meet vibration isolation requirement, need to adopt two-stage vibration isolation.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.
The two-stage vibration isolation structure of using is at present that a vibration insulation structure is placed on another vibration insulation structure and is formed.But, exist following not enough: 1, the height of equipment vibration isolation substrate doubles, and causes equipment crank.2, two vibration insulation structure vibration isolator natural frequencys selection of strictly not staggering, still can produce resonance phenomenon.3, equipment arranges after two-stage vibration isolation structure, the resiliently deformable of vibrating isolation system can cause equipment can cause the level of equipment to displacement in startup and dwell period, the equipment of the delivery pressure such as water pump and blower fan particularly, equipment and sections bracing with connective positional can be impacted and be caused infringement.How the height of two-stage vibration isolation structure and don't raising equipment vibration isolation substrate had both been set, can effectively eliminate resonance phenomenon, can effectively control startup, dwell period displacement again, still there is no up to now a kind of effective solution and cause two-stage vibration isolation structure to fail to apply.The more engineering work load of using is larger at present, and the machine room that expense is higher floats building structure ground as two-stage vibration isolation structure, rigid block and vibration isolator is set between equipment and floating building structure ground again and forms vibro-damping mount.
Summary of the invention
In order to overcome equipment, arrange that two-stage vibration isolation structure can produce that 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 vibration isolation substrate of control apparatus startup effectively, dwell period displacement.
The technical solution adopted for the present invention to solve the technical problems is: a kind of equipment vibration isolation substrate, by upper vibration insulation structure, lower vibration insulation structure, damping snubber, formed, it is characterized in that: upper vibration insulation structure is comprised of upper support steel plate, upper rigid block and upper vibration isolator, upper rigid block is cubic structure, and upper support steel plate is horizontally disposed with at upper rigid block top; Lower vibration insulation structure by lower rigid block, in Supporting Steel Plate, lower support steel plate and lower vibration isolator form, lower rigid block is four limit frame structures, lower support steel plate arranges at lower rigid block bottom level, and middle Supporting Steel Plate arranges at lower rigid block upper level; Upper rigid block is arranged in the middle of lower rigid block and on lower support steel plate, and lower rigid block is in upper rigid block surrounding; In vibration insulation structure surrounding, damping snubber is set.Upper vibration isolator is arranged between upper support steel plate and the lower support steel plate of lower vibration insulation structure, the rigid block of upper vibration insulation structure embeds between the lower rigid block and lower support steel plate of lower vibration insulation structure, and lower vibration isolator is arranged between the middle Supporting Steel Plate and terrace of lower rigid block.Vibration equipment bang path: equipment → upper rigid block → upper support steel plate → upper vibration isolator → lower support steel plate → lower rigid block → middle Supporting Steel Plate → lower vibration isolator → terrace, form the tandem compound of two-stage vibration isolation, not only reached the object of two-stage vibration isolation but also effectively reduced the height of equipment vibration isolation substrate.
Upper vibration isolator mounting point at upper support steel plate arranges mounting hole, cover access panel above, in the middle of access panel, establish vibration isolator positioning hole, A nut-welding is under upper support steel plate, access panel is used A bolt and A nut fixed connection, and lower support steel plate arranges vibration isolator setting sleeve.In rotation, the B bolt on vibration isolator top is adjusted the balance of vibration insulation structure.The C bolt on the lower vibration isolator of rotation top is adjusted the balance of lower vibration insulation structure.Rigid block is comprised of steel frame and counterweight, and the structural rigidity of steel frame should meet vibration and transmit balanced requirement, and the material of balancing weight can be used steel plate, ingot iron, heavy concrete etc. to be combined into required balance weight.
Distance in upper support steel plate and lower rigid block between Supporting Steel Plate should be greater than the maximum compression amount of deformation of vibration isolator.Distance between lower support steel plate and terrace should be greater than the maximum compression amount of deformation of lower vibration isolator.Upper and lower vibration isolator is a plurality of, along bearing structure central shaft, is symmetrical arranged, and to expand 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, certain in the change procedure of 0 ~ rated speed of the rotating speed in a flash forcing frequency of equipment is unique, it can not produce resonance with two kinds of different natural frequencies simultaneously, thereby effectively eliminates resonance phenomenon.
The damping snubber being comprised of carrying steel structure and rubber vibration insulating pad is set in vibration insulation structure surrounding, and the rubber vibration insulating pad of damping snubber is parallel with the vertical facade of vibration insulation structure, between leave certain gap, to prevent from vibrating, by damping snubber, transmit.Damping snubber can arrange between upper vibration insulation structure and terrace, also can between lower vibration insulation structure and terrace, arrange, and as arranged between lower vibration insulation structure and terrace, between upper vibration insulation structure and lower 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 two-stage vibration isolation structure height, control resonance and equipment offset phenomena, effectively reduce the transmission of device structure vibration solid.
