Regarding the use of water-cooled thermal shock test chambers , large faults do not occur, but there are always small troubles, such as slow cooling, overshoot, temperature, and other indicators, which are used by our users. Small problems often encountered during the test chamber process. Today, Xiaobian classifies everyone and provides a feasible solution for users to refer to during use.
Q: What should I do if the temperature of the water-cooled thermal shock test chamber is too high?
A: Set the PID setting parameters.
Q: What should I do if the low temperature does not reach the test index?
Answer: Observing the change of temperature is the slow temperature drop, or the temperature has a tendency to rise after the temperature reaches a certain value. If the former is to check whether the studio is dried before the low temperature test, it is necessary to ensure the test chamber. After drying, put the test sample into the work room and test it.
If the test sample in the studio is placed too much, the wind in the working chamber cannot be fully circulated. If it is not the above, it is necessary to consider whether it is a malfunction in the refrigeration system, so it is necessary to consult the professional of the manufacturer. The latter phenomenon is caused by the poor use of the equipment. The ambient temperature at which the equipment is placed is placed at a position other than 50 mm.
Q: What is the choice of the temperature and impact test residence time of the water-cooled thermal shock test chamber ?
A: In the dwell time of the impact process, how to decide the dwell time of the product to be tested depends on the quantity of the product to be tested and still depends on the raw materials of the test article.
Q: What should I do if the temperature of the water-cooled thermal shock test chamber rises very slowly?
Answer: First check the air circulation system, whether the regulating baffle of the air circulation is normal. If it is normal, check whether the motor of the wind circulation is running normally.
Q: In the damp heat test, the actual humidity will reach 100% or the actual humidity will be very different from the target humidity. What is going on?
A: It may be caused by the drying of the gauze on the wet bulb sensor. Then check whether the water in the sink of the wet bulb sensor is lack of water. The water level in the water tank is automatically controlled by a water level controller. Check whether the water supply system of the water level controller is supplied normally. Whether the water level controller works normally. Another possibility is that the wet gauze is hardened due to the long use time or the purity of the water supply, so that the gauze becomes hard and the gauze can not absorb moisture and is dry. The above phenomenon can be eliminated by replacing or cleaning the gauze.
Q: What should I do if the water-cooled thermal shock test chamber rises directly?
Answer: If the controller fails, the control instrument must be replaced.
Q: How do temperature shocks and temperature cycles resolve?
Answer: The temperature shock of the water-cooled thermal shock test chamber refers to sudden drop from high temperature to low temperature, for example, from 180 ° C to -55 ° C in a short time. When the temperature cycle refers to the test in the box, the temperature is evenly cooled in the tank. Or send heat.
