Constant temperature and humidity test chamber is a device used to test the performance of materials in various environments, which can simulate high temperature, low temperature, alternating humidity and heat conditions. Widely used in electronics, electrical appliances, mobile phones, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace and other products testing quality. Constant temperature and humidity test chamber is a commonly used climate simulation product in the laboratory. Some problems may be encountered in the middle of the use of maintenance and use also need to pay attention to some matters, good maintenance, not only to ensure the accuracy of the test, but also to ensure the service life of the equipment.
The constant temperature and humidity test chamber has smoke and odor discharge when doing high temperature in the first week, which is a normal phenomenon, because the newly manufactured test chamber will produce odor caused by oil smoke barbecued at the beginning of using high temperature. Especially when the new equipment does the temperature separately. Mainly due to electric heating and oil volatilization on the surface of the metal plate. Do a few more prices, open the door for air a few times on the basic dispersion.
When the ambient temperature is high, the overpressure of the compressor in the constant temperature and humidity test chamber is because the ambient temperature is too high, and the ambient temperature should be controlled between 5 ° C and 28 ° C, and the relative humidity is less than 85%. Because the ambient temperature is too high, the heat dissipation of the compressor is not good, which will affect the use of the compressor, the temperature is too high, the compressor will automatically protect, resulting in an alarm. At this time, you need to consider whether the equipment placement site is suitable, you can consult the equipment manufacturer. This is also a common problem, mainly because many of the equipment is limited by the customer's site or the site planning is not sufficient.
In the process of use, the water pipe turns yellow, and there is rust in the water tank, which is caused by the oxidation of water in the air for a long time, which is a normal phenomenon, and can be cleaned by physical methods (with a soft cloth or sponge).
The water quality deteriorates, the use is not pure water, or it is not cleaned up for a long time, and the fibers and microorganisms in the air inevitably appear in the water. If it does not come out, it will affect the wet bulb temperature, etc.
Wet-bulb gauze We generally recommend a test change, belongs to the experimental supplies. Contamination of wet bulb gauze will affect the detection accuracy of wet bulb temperature, and the accuracy of temperature and humidity will definitely be affected.
When the ambient temperature is too high, the cooling rate is relatively slow, which is a normal phenomenon. In order to better the performance of the equipment, it is recommended to control the ambient temperature at 20-25℃;
Constant temperature and humidity test chamber should be cleaned regularly inside and outside the machine dust, keep dry and clean.
Prevent burns and electric shock when working at high temperatures.
The above are easy to neglect when using the constant temperature and humidity test chamber, which requires attention and regular maintenance and cleaning to ensure the normal operation and service life of the equipment.
