Description
Technical field
The utility model relates to the vibration test electric vibration table, is specifically related to the inside and outside short circuit ring cooling structure of water cooled electrodynamic shaking table.
Background technology
Electric vibration table is by fixing magnetic field and is arranged in the shaking table that the vibration force that interaction produced that this magnetic field is connected with the coil of certain alternating current drives.In the electric vibration table structure, moving-coil as the oscillating component floating support in the magnetic field that field copper provides, AC impedance in the work when reducing the moving-coil high-frequency work, on the stage body of drive coil winding annulus gap of living in medial and lateral correspondence, be provided with inside and outside short-circuit ring structure, also claim two short-circuit ring structures, see shown in Figure 1.Shaking table in the high-frequency zone, can effectively reduce the equiva lent impedance based on inductance after installing short-circuited conducting sleeve additional, thereby improves input current and increase the output electric power, with the frequency of utilization scope of expansion shaking table.Inside and outside short-circuited conducting sleeve is normally made with the copper material of high conductivity, because inside and outside short-circuited conducting sleeve produces very big induction current because of the drive current of responding to moving-coil, thereby produces a large amount of heats, so also must cool off short-circuited conducting sleeve.In medium and small shaking table, the cooling of short-circuited conducting sleeve realizes by air blast cooling.For large-size water-cooling formula electric vibration table, the cooling of its inside and outside short-circuited conducting sleeve is passed to by the ring-type copper pipe that closely links together with short-circuited conducting sleeve normally that forced cooling water realizes.
In known technology in the past, the cooling structure of the external short circuit ring that external water cooled electrodynamic shaking table adopts is a tandem air ring tubular construction.The upper and lower cooling endless tube that is the external short circuit ring is in-line, and the heat that induction current produced when the external short circuit ring was worked at shaking table is mainly led away by its upper and lower cooling endless tube, its water route synoptic diagram, and as shown in Figure 2, upper and lower cooling endless tube is connected in series.It is bent by a water pipe and forms.The shortcoming of this air ring tubular construction is the bent tube technique more complicated, and cooling water flow after down air ring is heated again cooling go up air ring, cooling effectiveness is not high.
The cooling structure of the internal short-circuit ring that external water cooled electrodynamic shaking table extensively adopts as shown in Figure 3, only has a series connection chilled water pipe ring in the lower end of internal short-circuit ring.The shortcoming of this kind structure is when shaking table is worked near full thrust, and because of the short-circuited conducting sleeve induction current is very big, so the heating of short-circuited conducting sleeve is serious, the cooling effectiveness of cooling water ring does not catch up with, and causes the stage body temperature higher, may cause harmful effect to some test specimens.Therefore, never be well solved about the cooling problem of the inside and outside short-circuited conducting sleeve of large-size water-cooling formula electric vibration table for a long time.
Summary of the invention
The utility model proposes the inside and outside short circuit ring cooling structure of a kind of electric vibration table, its purpose is to improve existing inside and outside short circuit ring cooling structure, further improves cooling effect.
For achieving the above object, the technical solution adopted in the utility model is: the inside and outside short circuit ring cooling structure of a kind of electric vibration table, the following cooling endless tube of going up a cooling endless tube and a horizontal positioned of one horizontal positioned is set, face down bonding at last cooling endless tube and following cooling endless tube picks out water inlet pipe, weld out rising pipe at opposite side, water inlet pipe and rising pipe are communicated with last cooling endless tube and following cooling endless tube respectively, constitute cooling water channel structure in parallel with this.
Related content in the technique scheme is explained as follows:
1, in the such scheme, evenly cools off, water inlet pipe and rising pipe can be located to cool off on endless tube and the circumferential position of halving of following cooling endless tube and be communicated with in order to make cooling endless tube and following cooling endless tube.
2, in the such scheme, when last cooling endless tube is identical with following cooling endless tube diameter, a water inlet pipe and a rising pipe are set vertically.When last cooling endless tube and following cooling endless tube diameter not simultaneously, " Y " shape water inlet pipe and " Y " shape rising pipe vertically are set.
3, in the such scheme, go up cooling endless tube and following cooling endless tube for abundant cooling, the pore sectional area of water inlet pipe and rising pipe can be designed to 〉=on cool off the twice of endless tube and following cooling endless tube pore sectional area, the best is four times.
4, in the such scheme, in order to improve cooling effect, described cooling endless tube, following cooling endless tube, water inlet pipe and the rising pipe gone up all adopts the rectangle hollow pipe.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, for the external short circuit ring, owing to adopt cooling endless tube and the following cooling endless tube scheme that supplies water in parallel of going up, only flow through in the upper and lower cooling endless tube water route length of 1/2 loop of chilled water compared with prior art is that series connection cooling structure cooling water flow is through 1/4 of water route length.Thereby cooling effectiveness improves greatly.
2, for the internal short-circuit ring, owing to be provided with a chilled water pipe ring in parallel respectively in the outer wall lower end and the inwall middle and upper part of internal short-circuit ring, as shown in Figure 1, obviously, owing to increased a chilled water endless tube, and also change series connection water route is water route in parallel, shortened the distance of cooling water flow, so improved cooling effect greatly, it is low to have solved original structure short-circuited conducting sleeve cooling effectiveness, the difficult problem that the stage body temperature is high.
3, be welded by two endless tubes and two aqueduct solderings owing to this parallel-connection structure, so manufacturing process is simple and reliable.This programme is applied to receive good effect in the water-cooled Large Electric shaking tables such as 10 tons, 16 tons, 18 tons.
