Common faults and maintenance of high and low temperature damp heat test box

The main three functions of the high and low temperature damp heat test chamber are to create the environment of high temperature, low temperature and humidity, so as to make the performance change of the tested products in these three environments It is a common high temperature test equipment in the laboratory Common faults and maintenance of high and low temperature damp heat test box: 1 Only high temperature, no low temperature: the compressor works normally, it may be lack of refrigerant in the compressor, or it may be blocked by radiator, resulting in poor heat dissipation effect, or it may be blocked or leaked by pipeline, as long as there is one-to-one troubleshooting, it can be 2 Uneven temperature and humidity in the box: it may be the problem of the mixing fan Check the working condition of the fan first If there is noise, if the motor is burned, if the bearing is short of oil, etc 4 No humidity: first check whether there is water shortage, then check whether the humidifier is normal, and then check the electric control part.
