Embodiment
With reference to specific embodiment, the present invention is described in detail.Following examples will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that to the ordinary skill of this area
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection domain.
The present invention is a kind of tape deck for being used to visualize record and preserve electric thruster line of magnetic induction shape, main knot
Structure includes data board 2, soft magnetism recording materials particulate 3, heating plate 4 and support 5.Soft magnetism recording materials particulate 3 is spread in data board 2
On, the recording layer for solid (such as paraffin) under low softening point or low melting point, but normal temperature is scribbled on data board 2.Heating plate 4 is arranged on
On support 5, the multiple twin heater strip or water pipe of heating, and shaking device are furnished with heating plate 4, is powered or gives by heater strip
The mode that water pipe leads to hot water is heated, therefore will not produce the magnetic field for being enough to change electric thruster line of magnetic induction distribution of shapes,
Ensure the accuracy of measurement.Data board is used to placing soft magnetism recording materials particulate and shown using soft magnetism recording materials particulate, can
Depending on changing savepoint thruster line of magnetic induction shape.After tape deck is placed into test zone, shaking device with certain frequency and
Vibrations heating plate and data board, make the weight in the presence of magnetic field and vibrations of the soft magnetism recording materials particulate on data board more by a small margin
New arrangement, to show line of magnetic induction shape
When measuring electric thruster line of magnetic induction shape, the data board 2 for uniformly sprinkling soft magnetism recording materials particulate 3 is placed on
In heating plate 4, heating plate 4 horizontally extends into the region for needing to measure line of magnetic induction shape inside electric thruster, then electric thruster
Magnetic coil, which is powered, produces magnetic field, and heating plate shaking device energization work makes data board 2 vibrate by a small margin, soft magnetism recording materials are micro-
The meeting of grain 3 rearrangement in the presence of vibrations and magnetic field, records electric thruster line of magnetic induction shape, then shaking device stops work
Make, heater plate, the recording layer on data board is melted or softened, soft magnetism recording materials particulate 3 under gravity can
In the recording layer for being immersed to fusing or softening, enough time is waited, soft magnetism recording materials particulate 3 is fully arranged and be immersed to note
Stop heating after recording in layer, data board 2 is recovered normal temperature.Data board 2 recovers after normal temperature, and data board 2 just will record the line of magnetic induction
The soft magnetism recording materials particulate 3 of shape is fixed in the recording layer, realizes the visualization record of line of magnetic induction shape.
Data board 2 can be removed after completing record from tape deck, and being kept separately needs to record line of magnetic induction shape again
When, the data board 2 of soft magnetism recording materials 3 on new, spreading is taken on, can also continue to use original recorded line of magnetic induction shape
The data board (need not now dispense soft magnetism recording materials again) of shape.
The preferred embodiment to the present invention is done into a description below.
Embodiment one (recording layer is 52 degree of paraffin)
The recording layer material used in the embodiment as the data board of tape deck is paraffin.Paraffin has low softening
The characteristics of point (softening point of such as No. 52, No. 54 paraffin is respectively 52 DEG C, 54 DEG C), it is being heated to more than softening point temperature, can melting
It is melted into liquid.
When needing to carry out line of magnetic induction shape record, the uniform data board for dispensing magnetic recording material on the recording layer is placed in
In heating plate, tape deck then is placed into electric thruster needs the region by line of magnetic induction shape is recorded.Electric thruster magnetic
Coil electricity produces the line of magnetic induction, and then heating plate shakes, and the iron powder magnetic that the diameter at this moment laid on recording layer is less than 0.5mm is remembered
Record material shows line of magnetic induction shape under the double action that electric thruster magnetic field and heating plate shake, then heater plate,
The paraffin on data board is set to soften into liquid, the iron powder of recorded line of magnetic induction shape can sink to liquid under gravity
In recording layer, then heating plate stops heating, and electric thruster magnetic field stops being powered, and the liquid paraffin of recording layer can become solid again
State, and iron powder can be solidificated in paraffin, and line of magnetic induction shape is have recorded so as to visualize, and protected with very intuitive way
Deposit.
