Description
Technical field
This utility model is related to a kind of environmental test equipment, more particularly, to a kind of highway engineering stabilized with inorganic binder material
The high-low temperature test chamber of material test.
Background technology
With the development of science and technology, the raising of highway construction level, in production practices, to stabilized with inorganic binder material
Material it is also proposed higher requirement, and this is also that the accuracy to laboratory test is put forward higher requirement simultaneously.In highway construction
During, need to detect stabilized with inorganic binder material, can just use after meeting industry standard, carrying out inorganic combination
When material stabilizing material is tested, by subzero 30 DEG C to 70 DEG C above freezing, this requires that test temperature is adjustable, controllable to temperature fluctuation range.
Especially when temperature contracting test is carried out, temperature range is 60～-25 DEG C, and the amesdial that temperature contracting test is adopted is very sensitive, determines
Temperature shrinkage coefficient itself very little, generally less than 0.02mm.Current high-low temperature test chamber on the market, be using pallet with
The design of casing integration, i.e. pallet are directly contacted with the casing of proof box, the test specimen for having conserved are placed in pallet enterprising
Row test.This test method can cause result of the test inaccurate, as amesdial is more sensitive, produce during compressor operating
Vibration, the opening of test chamber door and closing can all cause the change of amesdial reading, it is impossible to obtain correct result of the test.Therefore
A kind of proof box is needed, while temperature height change is met, is avoided that compressor operating produces vibration to result of the test again
Impact.
Utility model content
The purpose of this utility model is to provide one kind and can not produce when compressed machine work, test chamber door opening and closing
The high-low temperature test chamber of vibration effect, to reach when being tested, makes the more accurate purpose of result of the test.
To reach above-mentioned purpose, this utility model provides a kind of high-low temperature test chamber not affected by vibration, its feature
It is that the proof box includes cabinet, inner chamber, pallet and support, refrigeration system, heater strip and temperature control system, the surface of internal cavity
Heat-preservation cotton is enclosed with, four circular holes are left in bottom, and the cabinet inner bottom surface is provided with compressor, condenser and reservoir, it is and interior
The vaporizer of intracavity constitutes refrigeration system, there is provided low temperature environment, and the heater strip heating air provides hot environment；The pallet
Pedestal upper end is connected through the circular hole of intracavity bottom with pallet, and lower end is supported on ground through cabinet, tray supporter and inner chamber
Between gap in filled with soft insulation cotton-wool；The pallet is supported on ground by tray supporter, not with proof box
Cabinet and lumen contact.Aerator is set at the top of the cabinet, and described heater strip is nichrome heating wire.The temperature control
System includes PLC, temperature inductor, behind instrumental panel.
The beneficial effects of the utility model are：Compared with existing high-low temperature test chamber, this utility model by test specimen pallet with
Proof box cabinet and inner chamber are separated, and can be prevented effectively from compressor and are operationally vibrated test is adversely affected, while also can
The adverse effect that vibration is caused when chamber door is opened and closed enough is prevented effectively from, so that result is more accurate, engineering construction is improved
Quality.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
This utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.

The function keys such as constant temperature degree and real time temperature display screen, are capable of achieving model selection and temperature control, and model selection is hot test mould
Formula and low-temperature test pattern, the two selects one to press.
Inner chamber 12 is provided with inside the cabinet 15,4 a diameter of 3.5cm holes, the inner chamber 12 are reserved in 12 bottom of inner chamber
Outside is enclosed with heat-preservation cotton 13, is provided with temperature sensor 9, vaporizer 10, blower fan 2, heater strip 3 and pallet 4 in inner chamber 12,
The pallet 4 is arranged below the tray supporter 7 of a diameter of 3cm, 7 upper end of the tray supporter through 12 bottom of inner chamber hole with
Pallet 4 is connected, and lower end is supported on ground, and the pallet 4 is not contacted with inner chamber 12 and cabinet 15, so as to ensure that pallet 4
On test specimen will not by vibration of compressor and casing vibration be affected.
15 inner bottom surface of the cabinet is provided with reservoir 5, compressor 6, condenser 14, the reservoir 5, compressor 6, cold
Condenser 14 is connected by pipeline and capillary tube with vaporizer 10, constitutes refrigeration system, humidifier 10 is provided with the outside of the cabinet 15,
Disclosure satisfy that the humidity environment of test requirements document.
When this utility model high-low temperature test chamber works, there are hot test and low-temperature test both of which, carry out high temperature examination
When testing, high temperature mode is selected on control panel 8 and design temperature is input into, heater strip 3 is started working, while blower fan 2 exists
Run under the drive of aerator 1, be heated the air-flow after silk 3 is heated and interior circulation formed in inner chamber 12, make test the temperature inside the box
Quick to raise, temperature sensor 9 detects and heats and be incubated；When carrying out low-temperature test,
Low temperature mode is selected on control panel 8 and design temperature is input into, compressor 6 is started working, and refrigeration system brings into operation, inner chamber 12
Interior air carries out heat exchange cooling with vaporizer 10, forms interior circulation, make in inner chamber 12 under the drive of ancient customs fan 12
Temperature is reduced rapidly, there is provided low temperature environment.
In sum, this utility model high-low temperature test chamber structure design more rationally, practical, hot test environment and low
Warm experimental enviroment can effectively avoid vibrating and test is interfered, and make result of the test more accurately credible, so as to improve
The efficiency and construction quality of follow-up work.
