Constant temperature and humidity testing machine in daily use, there are many things to pay attention to, including maintenance and maintenance, the following Xiaobian take you to know how to maintain and maintain the constant temperature and humidity testing machine.
1. Routine maintenance inspection of constant temperature and humidity testing machine
1, constant temperature and humidity testing machine water level can not be too high, so that the water overflows the water cylinder or too low so that the wet ball test cloth water absorption is abnormal, affecting the accuracy of the wet ball level of about six minutes full can be adjusted, the water level of the water cylinder can be adjusted to the level of the water box.
2, constant temperature and humidity machine environmental requirements:
There is no strong vibration around, no direct sunlight or direct radiation from other heat sources, no high concentration dust and corrosive substances around, and some space should be left between the equipment and the wall, and some space should be left between the tested items in the box, the inner wall of the box and the tested items. Regular maintenance according to the requirements of the manual, especially the maintenance of the condenser, is related to the service life of the compressor.
3, constant temperature and humidity machine should do routine checks every day:
Check if there is a problem with the power supply or if the plug is pulled out of the socket; Check whether the internal thermometer is out of the appropriate range, in this case, the item will heat up the refrigerator, check whether there are too many items at one time.
2. Routine maintenance of constant temperature and humidity machine
1, the freezing system of the constant temperature and humidity test box is the core of the test box, please check at least once a year all the steel pipes have no leakage, etc., the joints and welding joints, if there is oil leakage to be dealt with in time.
2, wet and dry balls and wet cloth should be checked frequently, when the surface of the test cloth is not clean or hardened, or after the high temperature is above 85 ° C control, continue to do temperature and humidity control. After inspection, if there is no water absorption, please replace it. It is related to the accuracy of humidity measurement. The test cloth is generally replaced once in three months. When replacing the test cloth, we should wipe the temperature measuring body with a clean cloth.
3, when the test product time arrives to take the product, must be in the shutdown state and the staff must wear dry, anti-electricity, wet gloves to take and put the product.
4. The ground around and at the bottom of the body of the constant temperature and humidity test chamber should be kept clean at any time, so as not to cause accidents and reduce performance when a large amount of dust is sucked into the unit.
