Specific embodiment:
As shown in Figure 1, including upper pipe clamp 1, lower tube clip 2, piston rod 3, cover 4, damper cylinder 5, magnetism shielding hood 6, spring
Upper platen 7, self-regulated spring 8, spring downward disk 9, permanent magnet 10, magnetism shielding hood sealing cover 11, every disk 12, magnetorheological damping liquid
13。
Wherein upper pipe clamp 1, lower tube clip 2 are bolted, and pipeline is clamped.And the screw thread of lower tube clip 2 and piston rod 3
It connects and passes through positioning finger setting.
Damper cylinder 5 is the cylindrical tube of inner hollow, connect and seals with cover 4 by screw.Cylinder is hollow
Section store flowing magnetorheological damping liquid 13 and the part that wherein moves reciprocatingly.
The most important part that the part and damping force to move reciprocatingly in cylinder generates.Including: magnetism shielding hood
6, platen 7 on spring, self-regulated spring 8, spring downward disk 9, permanent magnet 10, magnetism shielding hood sealing cover 11, every disk 12.
Piston rod 3 passes through bung 4 and needs the assistance of sealing element when moving reciprocatingly, and completes dust-proof, sealing and guiding
Function.
One end of piston rod 4 and magnetism shielding hood 6 are connected through a screw thread and nut check, while the nut also plays on spring
It is oriented to the effect of compression inside pressing plate 7 and magnetism shielding hood 6, prevents self-regulated spring 8 from loosening, falling.
Self-regulated spring 8 and magnetism shielding hood 6, the connection of permanent magnet 10 and locking as follows: the both ends start angle of self-regulated spring 8 is
0 °, therefore there is sufficient area to be closely embedded in 6 inner groovy of magnetism shielding hood and 10 inner groovy of permanent magnet.In order to prevent spring with it is interior
Loosening between slot, by the pressure of upper and lower 7,9 platen of self-regulated spring, self-regulated spring rises soft between magnetism shielding hood and permanent magnet
Property connection effect.There is the structure of guiding in magnetism shielding hood simultaneously to guarantee the straight reciprocating motion of permanent magnet.Upper press cover 7 is to pass through
Nut and magnetism shielding hood locking, lower cover 9 are locked by screw and permanent magnet.
It is connected through a screw thread between magnetism shielding hood 6 and magnetism shielding hood sealing cover 11, and close by moving between permanent magnet 10
Envelope forms the sealed environment for having certain space in magnetism shielding hood 6, moves reciprocatingly in magnetism shielding hood.
As shown in Figure 2；10 lower end of permanent magnet is connected by screw to every disk 12, is to prevent excessively every the effect of disk 12
Magnetic particle is adsorbed on permanent magnet 10 and causes local coagulation.Connect permanent magnet 10 and every disk 12 screw the selection of material be geneva
The soket head cap screw of body stainless steel, martensitic stain less steel have certain magnetic conduction effect, and also functioning to prevents magnetorheological damping liquid 13 heavy
The function of drop.
As the random vibration permanent magnet 10 of pipeline will move reciprocatingly in magnetism shielding hood 12, change magnetorheological damping liquid 13
The size of damping.Such as: when pipeline amplitude is larger, the volume that permanent magnet 10 exposes magnetism shielding hood 12 is larger, and exposing magnetic field is stronger, resistance
Buddhist nun's fluid viscosity becomes larger, and damping force is larger.Equally when pipeline amplitude is smaller, permanent magnet 10 exposes the small volume of magnetism shielding hood 12,
It is weaker to expose magnetic field, damping fluid viscosity becomes smaller, and damping force is smaller.
Working principle:
The present invention is applied to the vibration damping of the pipe vibration of petroleum and petrochemical industry transport high temperature high pressure, flammable explosive gas or liquid,
When assembling MR damper, pipe clamp clamps pipeline, and damper bottom is bolted with ground.Structure is simple, is not necessarily to
Peripheral hardware is connected, realizes the advantages of being displaced follow-up adjustment magnetorheological damping with pipeline random vibration, its working principles are as follows:
The energy that pipe vibration generates can be transferred to self-regulated MR damper to the clamping of pipeline by pipe clamp, due to soft
Property connection permanent magnet 10 the different reciprocating motion of amplitude can be done in magnetism shielding hood 12 according to the size of pipe vibration.According to pipeline
Different vibrations, permanent magnet 10 can generate different exposed areas, therefore the magnetorheological damping liquid 13 changed in magnetism shielding hood 12
Viscosity realize the function of MR damper self-control to change the size of damper damping force.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Within the technical scope of the present disclosure, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Subject to enclosing.
