Description
Technical field
The utility model belongs to the environmental unit system of vibration experiment, has been specifically related to the air cooling system of the preferable electric vibration table of a kind of test space environment.
Background technology
To be test products such as inspection machine, member bear external vibration to vibration test in transportation and use or the vibration that self produces is unlikely to destroy and can bring into play its performance, reach the fail-test of expected life.Present vibration test and carry out the needed vibration experiment of vibration test and in space flight and aviation, boats and ships, automobile, telecommunications, household electrical appliances instrument etc. require the industry of product reliability, more and more bringing into play important effect.
The frequency range of electric vibration table can be from several conspicuous to thousands of conspicuous, load-bearing capacity can restrain hundreds of kilograms from thousands of, and waveform is better, and control is convenient, relatively being suitable for realizing the experimental waveform and the spectral pattern of various complexity, is most widely used a kind of shaking table in all kinds of vibration tests.Electric vibration table can generate heat in the course of work, and its reason is that the electric current that flows through drive coil and magnetizing coil on the one hand generates heat because of the conductor resistance loss, and conductor generates heat because of eddy current loss in the drive coil alternating magnetic field on the other hand.Depend merely on the temperature rise that natural cooling can not the restriction electric vibration table, at present electric vibration table forces the type of cooling to mainly contain air-cooled and two types of liquid-cooleds.Air-cooled is to force cooling with fan blower, though the cooling effectiveness of this mode is lower than liquid circulation cooling, it is simple in structure, cost is low, still is suitable for the cooling of medium and small electric vibration table so far widely.
As Fig. 1, the air intake mesh 2 that communicates with air gap is offered on magnetic cylinder cylinder body 1 top of existing air-cooled electric vibration table, set out air port 3 in the bottom of magnetic cylinder and connect air exhauster, make the inter-air space form negative pressure, discharge by the air-out passage again after the pressure air is entered by the air intake mesh by air exhauster.There are many shortcomings in the air-cooled electric vibration table of this kind, at first, the vibration test environment is sealing or hemi-closure space, for guaranteeing the degree of accuracy and the anti-explosion safety of vibration test, need be provided for this lab space air and thermoregulator equipment, after this shaking table is opened, the circulation of big air quantity can cause the overload operation of air and temperature control equipment, and influencing the stable of test space, there is potential safety hazard in circulation and the air that do not efflux can make dustiness improve greatly in explosion-proof environment; Even even the air outlet of the air-cooled electric vibration table of this kind is arranged on this test space outside on the other hand, still can cause test space to become negative pressure state because air inlet is positioned at test space, influence the stable of experimental enviroment and in explosion-proof environment, have potential safety hazard.
The utility model content
The purpose of this utility model has been to provide a kind of simple in structure, air cooling system of test space not produced the preferable electric vibration table of any influence, air cooling effect, it is big to the test space influence to have solved existing air-cooled electric vibration table, and there is hidden danger in anti-explosion safety and may influences the difficult problem of test findings.
For above goal of the invention, the technical solution adopted in the utility model is as follows:
A kind of air cooling system of electric vibration table, comprise air-cooled electric vibration table, it is characterized in that on the magnetic cylinder cylinder body of described air-cooled electric vibration table or go up the cover circle and go up to connect the air inlet that can directly link to each other with air intake passage that communicates with the inter-air space is set, the air inlet connection is provided with air intake passage, the air outlet that the setting of magnetic cylinder inferior part of the cylinder block communicates with the inter-air space, the air outlet connection is provided with the air-out passage.
Specifically, connection is provided with an air inlet or a plurality of air inlets is set on the upper end sidewall of described magnetic cylinder cylinder body, and air inlet connects the air intake passage that the blast pipe composition is set.
The air cooling system of described electric vibration table comprises that also one places the test space of air-cooled electric vibration table, described test space is sealing or hemi-closure space, the other end air inlet of described air intake passage is arranged on the outside of test space, and the other end air outlet of described air-out passage also is positioned at the outside of test space.
Described air intake passage is provided with booster fan, provides to force cooling air intake power.
Described air-out passage is provided with negative-pressure air fan, provides to force cooling air-out power.
Air intake passage can be arranged on indoor, and is provided with down, can prevent that water droplet from entering air inlet.
The air cooling system of this electric vibration table adopts the air inlet that can be connected with air intake passage to replace existing annular air intake mesh, the space of collecting folk songs of air cooling system is provided with position adjustment according to the air intake passage air inlet, the air-out space of corresponding air cooling system also can be adjusted according to the position of the air outlet of air-out passage, eliminates the negative effect that air cooling system causes the test space of electric vibration table.Because the test space of electric vibration table mostly is sealing or semi-enclosed testing laboratory, test space temperature and dustiness all there is strict requirement, if the air outlet of electric vibration table or in the air inlet one or two are arranged in the test space, the temperature of test space can sharply raise on the one hand, cause the air-conditioning overload operation of test space, the air flow of big flow can cause dust content of air to improve on the other hand, increases the quick-fried hidden danger of dirt.Can effectively eliminate the problems referred to above by being provided with of air intake passage and air-out passage, the stability in warranty test space, the high temperature air-out of the passage of air-out simultaneously can not influence or be drawn into the air inlet of air intake passage, has guaranteed the constant operation of air cooling system and the raising of air-cooled efficient yet.
Described air inlet can directly be connected on the outer wall of electric vibration table magnetic cylinder cylinder body, and the number of air inlet can be made as one, also can be made as two or most.Provide the blower fan of air blast cooling can be mounted in negative-pressure air fan on the air-out passage, can on air intake passage, set up booster fan simultaneously.
The beneficial effects of the utility model are, the air cooling system of this electric vibration table compared to existing technologies, its cooling effect is better, and the stability and the cleanliness factor of test space have been guaranteed, eliminate anti-explosion safety hidden danger and a large amount of heat exchange air to the spinoff of the artificial atmosphere facility of test space, make the vibration test process not be subjected to the influence of air cooling system.The air cooling system of this electric vibration table can be applied in the pilot system of various air-cooled electric vibration tables.
