A few days ago, the unit's high and low temperature damp heat test chamber suddenly appeared noise, and it sounded from time to time. Everyone made a move, and finally found that there was something on the side of the high and low temperature damp heat test box, and it did not ring immediately after taking it away. I believe that you may also encounter such a problem. A good test box suddenly has noise. It may not be that the device itself has failed, but the method is not used properly. Today, I will discuss with you the noise of high and low temperature damp heat test chamber.
First understand why there are noises in the high and low temperature damp heat test chambers. There are three types:
First, the high-low temperature damp heat test chamber is placed in an uneven position. The ground level of the high-low temperature damp heat test chamber is not flat or the installation is not stable, which is the common cause of noise generated by the high and low temperature damp heat test chamber. The solution is to twist the adjusting screw on the bottom of the high and low temperature damp heat test chamber to adjust the height. When the adjusting screw touches the ground, the four feet are in contact with the ground.
Second, there are items placed on top of the high and low temperature damp heat test chamber. The high-low temperature damp heat test chamber and the items placed on top of it will resonate when the motor starts, causing noise. Moving the items on the top of the device will prevent it from resonating, and the noise will naturally be eliminated.
Third, there are small things falling into the machine part at the back of the high and low temperature damp heat test chamber. The rear machine part of the high and low temperature damp heat test chamber (lower part behind the test chamber) has fallen into small things, such as parts, gadgets, etc., and noise is also generated. Solution: After cutting off the power of the test box, the small items that fall into the machine will be taken out and the noise will disappear.
Well, understand why the high and low temperature damp heat test chambers have noise, so how can we prevent this from happening? And listen to the next decomposition.
