Загальні проблеми та методи калібрування камери для випробувань на термічний удар

Thermal shock test chamber is a kind of experimental equipment used to simulate the durability and stability test of goods under rapid temperature changes. It can simulate the thermal expansion and contraction of goods in different temperature environments to test the performance and durability of goods in different temperature environments.

Q&А
The temperature reading is inaccurate.

The temperature is unstable.

The device is not evenly heated or cooled.

The device is leaking or the tank capacity is insufficient.

An error occurred in program operation.

Calibration method
Temperature calibration: Place the thermometer in the thermal shock test chamber and set the thermal shock test chamber to a known temperature. After waiting for some time, the thermometer reading is compared with the temperature reading displayed in the thermal shock test chamber. If there is a difference, a calibration adjustment is required. Calibration can be done by adjusting the temperature calibration parameters in the controller.

Equipment uniformity calibration: Place several thermometers inside the thermal shock test chamber and set the thermal shock test chamber to a known temperature. After waiting for a period of time, compare the readings at each measurement point to see if they are consistent. If there is a difference, a uniformity calibration adjustment is required. This can be achieved by adjusting the working mode and position of heating, cooling and fans, as well as adjusting the position of items inside the cold and thermal shock test chamber.

Equipment tank capacity calibration: Fill the tank in the hot and cold shock test box with water, and record the water capacity. Then set the cold and heat shock test chamber to a certain temperature, measure for a period of time, а потім вилийте резервуар і запишіть об’єм води, що залишився. Subtract the remaining water capacity from the previously recorded water capacity to obtain the amount of water used by the thermal shock test chamber at this temperature. Якщо кількість використаної води не відповідає місткості, зазначеній у специфікації, необхідне калібрування ємності резервуара. It can be calibrated by adjusting the tank capacity parameters in the controller.

Нагадуємо: the thermal shock test chamber needs to be calibrated and maintained regularly. В той самий час, необхідно регулярно очищати внутрішню частину обладнання, перевірити працездатність і стан опалення, охолодження, КОНТРОЛЬ, sensors and other equipment, а також своєчасно замінювати або ремонтувати несправні деталі. В додаток, рекомендується проводити технічне обслуговування пристрою відповідно до інструкції з експлуатації та інструкцій з обслуговування, наданих виробником, щоб забезпечити тривалу стабільну роботу пристрою.

Питання, що потребують уваги
In the process of using the thermal shock test chamber, the following points should also be noted:

Arrange the position of the sample to ensure that the sample can receive uniform temperature distribution.

Do not accumulate too much debris or samples inside the cold and thermal shock test chamber to avoid affecting the operation of the equipment and the accuracy of the data.

According to the actual needs, the temperature range and accuracy of the cold and hot impact test chamber are reasonably selected to avoid the inaccurate test data caused by the mismatch of equipment parameters.

Prior to testing, pre-heat or pre-cool the equipment to ensure that the required temperature conditions can be achieved.

In the process of using the equipment, temperature changes and test data are recorded in time, and analyzed and processed according to needs.

Коротко, the cold and thermal shock test chamber is a commonly used test equipment, but it is necessary to pay attention to the use and maintenance of the equipment during use to ensure the stability of the equipment and the accuracy of the test data.
