Pipeline is the common components in industrial system connecting the setting of the power such as air compressor machine, water pump, undertakes suction and conveys
The task of fluid, because the suction inlet of pipeline and delivery outlet have certain pressure differential, the quality of air compressor machine and water pump and machinery
All there is the error that some are difficult to avoid that in assembling, when fluid flows in pipeline, because the temperature difference can produce certain local pressure,
The proper flow of fluid when there is bubble in fluid, can be affected, so that pipeline produces vibration and noise.Pipeline shakes
When dynamic, its internal works can be destroyed, lead to the service life of pipeline to shorten, meanwhile, the noise that pipe vibration produces can be dirty
Dye environment.
In order to avoid pipeline because vibration is damaged, generally bracing frame is set outside pipeline, and in pipeline and bracing frame
Between elastomeric material is set, because the damping of elastomeric material is less, and be rigid contact it is difficult to by a relatively large margin and bracing frame between
The vibration of suppression pipeline；When pipeline is used for hot environment, elastomeric material meeting creep deliquescing, lead to stay between pipeline and bracing frame
There is certain space, when pipeline occurs vibration, bracing frame can not be played a supporting role, and accelerates the damage of pipeline.

On the basis of technique scheme, described damping material is the grains of sand, metal damps silk or clay.
On the basis of technique scheme, in place of support frame as described above and the connection of the first pipe clamp, it is provided with cushion block.
Compared with prior art, it is an advantage of the current invention that:
(1) the big dampening bracket for pipe vibration-damping of the present invention includes the first memory alloy pipes and the second memorial alloy
Pipe, the first memory alloy pipes and the second memory alloy pipes are all made using marmem, and marmem is subject to external force
During effect, can deform upon, after external force disappears, can return to the original form.Therefore, when pipeline is vibrated or impact
During power, the first memory alloy pipes and the second memory alloy pipes can first deform, vibration and impact that buffering pipe is subject to, so
Recover original shape more afterwards, pipeline is back into origin-location；To have phase transformation stagnant for memory metal shape memorial alloy simultaneously
Process energy absorption ability, can the vibration that is subject to of extraction duct or impulsive force, i.e. the first memory alloy pipes and the second memorial alloy

All it is filled with damping material, damping material has mobility, be subject in corresponding first memory alloy pipes or the second memory alloy pipes
To when vibrating or impact is deformed, the damping material within its deformation position is squeezed and flows in pipe elsewhere,
Ability can be converted into heat and dissipate by friction and tube wall between for the damping material itself, reach the purpose of energy-absorbing.
(3) the big dampening bracket for pipe vibration-damping of the present invention, the aperture of the first installing hole is more than the first fixing axle
Diameter, the aperture of the second installing hole is more than the diameter of the second fixing axle so that the first fixation clamp (or second fixation clamp) is subject to one
While fixed position limitation, can with respect to the first pipe clamp (or second fixation clamp) carry out a certain degree of axial, radially, week
To movement and rotation.When pipe vibration in first fixation clamp and the second fixation clamp is excessive, pipeline being capable of the first pipe clamp relatively
Or second pipe clamp there is a certain degree of movement and rotation, preventing from being rigidly connected leads to the first pipe clamp or the second pipe clamp moment of torsion mistake
Greatly so that the first pipe clamp or the second pipe clamp damage.
