Cooling thermostats is a kind of mechanical equipment that can provide high-precision low temperature and constant temperature source. It controls the temperature of circulating medium through thermal circulation system to achieve the results of low temperature and constant temperature. If the set temperature is not reached, it will automatically heat the whole tank to improve the accuracy of constant temperature and reach the set temperature.
In the daily use of laboratory water bath, if the set temperature occurs but the equipment does not operate according to the set temperature, first check whether the power supply of the equipment is connected properly. If there is no problem, Check whether the heating insurance or refrigeration insurance is normal (check steps: first turn off the power supply of the machine, unplug the power line, and then open the insurance cover to see whether the fuse is blown and whether the power line is connected normally. After the maintenance is normal, close the insurance cover, plug in the power line and turn on the equipment switch).
When the refrigeration speed of the cold trap bath drops significantly and the noise is getting louder and louder, because the circulating water bath is a high-precision equipment, the above problems will occur if it is not maintained frequently. If these two problems occur, please shut down and check the hood of the cooling port, wipe off the dust and sundries with a dry cloth, open the cooling port and brush off the dust and sundries on the fan with a brush.
When you find that the connecting pipe leaks air and water, don't panic. First check whether it is formed by the condensation of water vapor in the air. If so, ignore it, wipe it off, and reduce the humidity of the environment. If it is not the water vapor of the air, please turn off the equipment, carefully check the leakage, unscrew the connection, wipe it clean, seal it with high-strength glue, connect it again, and start the machine for inspection.
I believe everyone has understood how to quickly deal with the common faults of thermostatic water bath, but I also need to remind you that the use of high-precision equipment is inseparable from regular maintenance. If it is maintained regularly, many faults can be avoided.
