How to eliminate the difficult problems of the salt spray test chamber

How to eliminate the difficult problems of the salt spray test chamber Many people will blame the poor quality of the salt spray test box in actual use. However, the relevant departments have used statistical data to tell us that more than 50% of these problems are caused by operation. Only 5% is the quality problem of the salt spray test box itself. Therefore, it is very important whether the operation of the salt spray test chamber is standardized. However, once the salt spray test box fails, let's not be in a hurry. Today's editor summarizes the troubleshooting method of the salt spray test box for not heating up. You can learn it! 1. The cabinet of the salt spray test chamber does not heat up: 1. Check whether the water injection volume inside the tank is added to the water level; 2. Check whether the heating tube inside the cabinet is damaged, and whether the voltage at both ends of the heating tube is normal, whether there is 220V voltage input, check whether the real-time temperature display of the instrument is normal, if the display temperature is found to be too high, the device will automatically display overtemperature protection; 3. Whether the set temperature point of the meter is correct, whether the sensor transfer temperature is normal, whether the meter heating output is normal, check whether the solid state relay is damaged, and check whether the over-temperature protection point inside the meter is set too low; 2. The reason why the saturator of the salt spray test chamber does not heat up is as follows: 1. Check whether the water level inside the saturator meets the requirements; 2. Check whether the over-temperature alarm lamp on the panel is on, check whether the voltage at both ends of the heating tube of the saturator is normal, whether there is a 220V voltage input, check whether the temperature display on the meter is normal, and whether the output is normal, if the voltage is normal, the saturator If the temperature is not increased, it can be determined that the heating tube is damaged; 3. If there is no voltage, the saturator will not heat up, check whether there is DC voltage at the signal end of the solid state relay, and whether there is AC voltage at the output end. If there is no signal from the solid state relay, it will not output the voltage normally. If this happens, check the output terminal of the meter for DC voltage output. If there is no DC voltage, it can be determined that the meter is damaged.
