The constant temperature and humidity test chamber is a necessary test equipment in the fields of aviation, automobiles, home appliances, scientific research, etc., and is used to test and determine the parameters of electronic electrical, materials and other products after the temperature environment change of high temperature, low temperature, or constant humidity heat test And performance. It is an indispensable test tool in the laboratory, and its price is relatively high. So, is there a correct maintenance method for the equipment? Below, the technical department of Beijing Yashilin Experimental Equipment Co., Ltd. for everyone in practice Provide 5 small methods: 1. Refrigeration systems such as condensers, copper tubes, evaporators, and compressors should be cleaned regularly, and dust should be removed in time The refrigeration system is the core component of the machine, and the condenser should be maintained regularly on a monthly basis. Use a vacuum cleaner or a brush to remove the dust attached to the condenser cooling mesh or brush or use high-pressure air to remove the dust. This can avoid the equipment Overpressure, overload and other phenomena occur. 2. The over-temperature protector in the box should be checked regularly When the constant-temperature and constant-humidity test box is in operation, the maximum value of the over-temperature protection is increased by 20 ° C ~ 30 ° C. When the temperature in the test chamber rises to the set point of the over-temperature protection, the power supply of the heater will stop, The temperature warning light is on but the fan is still running. If it runs for a long time and is unattended, please make sure to check the over-temperature protector before operation, whether it is set properly (the setting of the over-temperature protector is 120 ℃) 3. The wet ball gauze in the box should be replaced as appropriate When the surface of the wet ball gauze is not clean or hard, or the device is not used for a long time, etc., the wet ball gauze should be checked or replaced before the next humidity test.The manufacturer recommends to replace it every three months (the gauze must be clean) This action can avoid the phenomenon that the device displays a humidity display of 100%, or the humidity does not increase or fluctuates greatly. 4. Cleaning and maintenance of the inside and outside of the constant temperature and humidity test chamber 1. The internal impurities should be removed before the test box is operated 2. Clean the power distribution room at least once a year to avoid the dust in the air being absorbed on the surface of the machine or on the accessories such as condensers and evaporators. 3. The outside of the cabinet must also be cleaned more than once a year. Wipe with soapy water first, but do not use corrosive liquids. 5. Inspection and maintenance of humidifier in constant temperature and humidity test chamber The water storage tank in the humidifier should be replaced once a month to ensure that the water quality is clean. The humidified water must be pure water, because the impurities in the tap water are more likely to cause blockage of the water pipe and affect the progress of the experiment. .
