The magnet and the utensil which comprises the magnetic current varying liquid are installed on the bracket. The magnetic field intensity testing probe is installed on the magnet. The utility model is testing equipment which is formed by using the principle that the magnetic conductivity of the magnetic current varying liquid is changed with the change of the solid content of the magnetic current varying liquid. The utility model is mainly applied to the preparation and the performance evaluation of the magnetic current varying liquid.
Description
(1) technical field
The utility model relates to a kind of novel test instrument, specifically a kind of proving installation of testing magnetic flow liquid sedimentation, layering situation.
(2) background technology
Magnetic flow liquid presents low viscous Newtonian fluid characteristic under zero magnetic field condition; And under strong magnetic field action, then present the Bingham bulk properties of high viscosity, lazy flow.Because the rheology of magnetic flow liquid under the action of a magnetic field be moment, reversible, and the shear yield strength after its rheology has stable corresponding relation with magnetic field intensity, so is a kind of intellectual material of of many uses, function admirable.
At present, magnetic flow liquid has begun to be applied to grind the sensor and the industries such as mining, printing of the Rest of grasping mechanism, making-up shop anomalistic object of (polishing) technology, valve and sealing, family fitness device, mechanical arm and instrument and meter for automation, robot, in the middle of its numerous applications, studying application maximum, with fastest developing speed is car seat vibration damper, brake, active drive device and civil structure vibration damper.
The evaluation index of magnetorheological fluid performance quality is except its certain magnetic field down cut yield force size, and another important index is to leave standstill when depositing the sedimentation situation of magnetic-particle for a long time.If precipitum presents soft mud shape, then function admirable; If present rigid conglomeration or the sedimentation of knot layer, then performance is inferior.In addition, the settling velocity of magnetic-particle has also directly influenced the final sedimentation situation of magnetic flow liquid.
Up to the present, also there is not a cover can test the instrument of the magnetic-particle settling velocity and the sedimentation layering situation of magnetic flow liquid both at home and abroad.
(3) utility model content
Provided by the utility model is a kind of magnetic flow liquid sedimentation hierarchical tester that can test the magnetic-particle settling velocity and the sedimentation layering situation of magnetic flow liquid.
The purpose of this utility model is achieved in that it comprises magnet, magnetic field intensity test probe, the vessel that hold magnetic flow liquid and support, magnet and to hold the vessel of magnetic flow liquid rack-mount, and the magnetic field intensity test probe is installed on the magnet.
The utility model can also comprise some architectural features like this:
1, described magnet is solenoid or permanent magnet.
2, the vessel that hold magnetic flow liquid are installed in an end of magnet.
3, have breach on the magnet, the vessel that hold magnetic flow liquid are installed in indentation, there.
4, support is made up of base plate and the magnet support bar that is installed on the base plate, and magnet is installed on the magnet support bar, is provided with guide rail and the locking mechanism that moves up and down between magnet and the magnet support bar.
5, the container that holds magnetic flow liquid is installed on the base plate of support, and holding between the container of magnetic flow liquid and the base plate has moving guide rail.
The utility model utilizes under the different sedimentation situations, and the magnetic permeability of magnetic flow liquid is different and test its layering situation.This instrument has great importance for the exploitation and the performance evaluation of magnetic flow liquid.Magnetic field intensity in the electromagnet gap will be different and different along with the performance of object in its gap, and when the magnetic flow liquid concentration ratio in the middle of it was big, its magnetic field intensity was just than higher, otherwise, then lower.In that fixedly magnetic flow liquid vessel position is motionless, and when moving up and down magnet, because the concentration difference of magnetic flow liquid differing heights, therefore, the magnetic field intensity in the magnet gap also can change with the variation of magnet along short transverse.By comparing the magnetic field intensity of differing heights each point, we just can know the sedimentation layering situation of magnetic flow liquid.In addition, if our further its layering situation of more same sample situation over time, we just can estimate the excellent summary situation of change of its settling property.
The utility model is the testing apparatus that the principle of utilizing the magnetic flow liquid magnetic permeability to change with the magnetic flow liquid solid content is made.The utility model is mainly used in the development and the performance evaluation of magnetic flow liquid.Have advantages such as simple in structure, easy to use.
