Description
Technical field
The utility model relates to the vibration test electric vibration table, is specifically related to water cooled electrodynamic shaking table drive coil winding cooling structure in parallel.This parallel cooling structure not only suitable water and is applicable to other liquid of wet goods and carries out work as heat eliminating medium as heat eliminating medium.
Background technology
Electric vibration table is by constant D.C. magnetic field and is arranged in the shaking table that the electric power that interaction produced that this magnetic field is connected with the coil of certain alternating current drives.Its basic structure mainly partly is made up of stage body (magnetic cylinder, magnetic cylinder cap, iron core, magnetic cylinder bottom), field coil, moving-coil, support spring and guide piece and gudgeon air spring isolation mounting, bearing etc.Wherein, moving-coil is made up of the skeleton of band work top and the drive coil that is wound on the skeleton as the critical piece of oscillating component.During shaking table work, in field coil, feed DC current---exciting current, then in annular space (working gas gap), produce very strong radial D.C. magnetic field at stage body; Hang in the drive coil be positioned among the working gas gap and pass to exchange current being supported spring and guide piece, then the drive current of this interchange and the direct current stationary magnetic field among the working gas gap interact and produce electric power---the exciting force of alternation, this exciting force is delivered to by moving coil framework on the table top that test specimen is installed, to promote the test specimen vibration.
Because the electric current that drive coil feeds at work is very big, can cause the drive coil heating, therefore need implement to force cooling to it.The existing type of cooling has two kinds of air-cooled and water-cooleds, the air-cooled electric vibration table that generally only is suitable for the middle-size and small-size thrust below 5～6 tons, and all adopt water-cooling project usually for 5～6 tons of Large Electric shaking tables more than the thrust.
For a long time, water-cooling pattern to the electric vibration table drive coil all adopts the tandem cooling scheme in the world, it is the design proposal that the drive coil winding adopts hollow tubular wire-wound group, chilled water enters from the hollow pipeline of drive coil one end, the whole winding of flowing through flows out (as shown in Figure 1 and Figure 2) from the pipeline of the other end again, realizes the tandem Forced water cooling with this.Yet, from practical application effect, still can for the electric vibration table cooling effect below 10 tons, but for more than 10 tons, the electric vibration table of (as 16 tons) more than 15 tons especially, cooling effect is relatively poor in its actual use, particularly when the full thrust work of shaking table or the temperature of primary cooling water in summer (tap water) when higher, because cooling does not catch up with, coil heating is serious, often burns out the fault of drive coil winding.Analyze its reason, nothing more than being: in the series connection type of cooling, because the water route length of cooling water flow warp is the length of whole drive coil winding, when electric current is very big, the temperature of coolant outlet is inevitable very high, in case exceed the ability to bear of drive coil or be in the condition of high temperature for a long time, occur above-mentioned fault easily.
In order to solve the defective of the above-mentioned series connection type of cooling, external famous shaking table producer has just adopted the measures such as (cooling-water machine, two grade cooling towers) of additional cooling device to improve cooling effect.Although this measure can be dealt with problems, the deficiency that exists has: 1, increased equipment cost to the user; 2, make equipment complicated more; 3, in the use operation, bring many troubles; 4, it is bigger to take the testing laboratory place.Therefore, the cooling problem about large-size water-cooling electric vibration table drive coil winding never is well solved for a long time, has now become the hard nut to crack in the electric vibration table manufacturing field.
Summary of the invention
The utility model proposes a kind of electric vibration table drive coil winding water-cooling structure in parallel, its purpose is to improve the water-cooling pattern of existing high thrust electric vibration table drive coil winding, further improves cooling effect.
For achieving the above object, the technical solution adopted in the utility model is: a kind of electric vibration table drive coil winding water-cooling structure in parallel, the drive coil winding is made of the coiling of hollow tubular lead, at least weld out an aqueduct in side, hollow tubular lead middle part, described aqueduct number is the odd number root, and in the setting of being separated by of hollow tubular conductor length direction, aqueduct and hollow tubular guide wire lumen form the three-way pipeline structure, constitute drive coil cooling water channel structure in parallel with this.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described " weld out an aqueduct at least in side, hollow tubular lead middle part, described aqueduct number is the odd number root ", its quantity are specially one, three, five, seven, nine etc.
