Working state of high-precision water chiller

No matter how good a product is, there are times when it fails. How can you quickly determine the failure and keep the high-precision water chiller in a good working state.

1. In high temperature experiments, if the temperature change does not reach the experimental temperature value, you can check the electrical system and eliminate faults one by one. If the temperature rises slowly, it is necessary to check the air circulation system to see if the regulating damper of the air circulation is opened normally. Otherwise, it is necessary to check whether the motor of the air circulation operates normally. If the temperature overshoot is severe, it is necessary to set the setting parameters. If the temperature rises directly and the temperature is protected against overheating, the controller fails and the control instrument must be replaced.

2. If the low temperature does not meet the experimental indicators, then you should observe the temperature change, whether the temperature drops slowly or there is a tendency for the temperature to rise after reaching a certain value. Consider whether there is a fault in the refrigeration system, and ask the manufacturer’s professional personnel for maintenance. This phenomenon is caused by the poor operating environment of the equipment. The ambient temperature and location of the equipment (the distance from the back of the box to the wall) should meet the requirements (specified in the equipment operation instructions).

3. High precision water chiller with slow or no temperature rise: Check whether the heating system has faults, such as whether the heating pipe is broken, whether the heating pipe wiring is loose, whether the control instrument is burned out, and whether the circuit is open. No humidity: first check whether there is a water shortage, then check whether the humidifier is normal, and then check the electrical control part. Only high temperature, no low temperature: The compressor works normally, which may be due to a lack of refrigerant in the compressor, a blockage in the radiator, resulting in poor heat dissipation, or a blockage or leakage in the pipeline. As long as there is a targeted troubleshooting, it is sufficient. Uneven temperature and humidity in the box: It may be a problem with the mixing fan. It is necessary to check the working condition of the fan first. For example, whether there is noise, whether the motor is burned, and whether the bearing is short of oil.
