Problems solved by technology

[0003] (1) The temperature range is relatively narrow, only simple high or low temperature;
[0004] (2) Generally, there are only temperature and pressure indicators, and damp heat tests cannot be done;
[0005] (3) When testing in different temperature ranges or at different pressures, the motor is eccentric due to slight deformation of the pressure-bearing layer, which will generate noise to varying degrees;
[0006] (4) There is no steam-water separation device, and the water vapor is easy to condense in the pumping pipeline when the humidity is adjusted, which will cause rust, corrosion of the vacuum pump, and deterioration of the vacuum pump oil.

Abstract

The invention relates to the technical field of environmental testing instruments, in particular to a high low temperature damp and hot low gas pressure test box. The high low temperature damp and hot low gas pressure test box comprises a box body, a heating system, a refrigerating system, a vacuum system, an electrical cabinet and an electrical system, wherein a box door is arranged at the front end face of the box body, and an observing window is arranged on the box door; the box door is connected with the box body in a sealing manner; the heating system and a vacuum chamber are arranged at the upper part in the box body, and a sample stand is mounted in the vacuum chamber; the heating system, the refrigerating system and the vacuum system are respectively connected with the electrical system through a circuit. The high low temperature damp and hot low gas pressure test box also comprises a humidifying system, and the humidifying system is arranged outside the vacuum chamber in the box body and is communicated with the interior of the vacuum chamber through a pipeline. An electric valve is arranged on the pipeline, and the humidifying system and the electric valve are respectively connected with the electrical system through a circuit. Compared with the prior art, the high low temperature damp and hot low gas pressure test box integrates humidity, high low temperature and low gas pressure, and the function of the test box can be furthest performed, so that the test box can simulate a complicated real test environment, and the test accuracy of tested products is improved.

Description

[technical field] [0001] The invention relates to the technical field of environmental testing instruments, in particular to a high and low temperature damp heat and low pressure test box. [Background technique] [0002] At present, the scope of application of vacuum test chambers in production and life is becoming wider and wider. With the development of science and technology, the requirements for test chambers are getting higher and higher. The common vacuum test chambers on the market mainly have the following problems or deficiencies: [0003] (1) The temperature range is relatively narrow, only simple high or low temperature; [0004] (2) Generally, there are only temperature and pressure indicators, and damp heat tests cannot be done; [0005] (3) When testing in different temperature ranges or at different pressures, the motor is eccentric due to slight deformation of the pressure-bearing layer, which will generate noise to varying degrees; [0006] (4) There is no...
