Precautions for the use of cooling and heating circulation device for lithium battery testing
As a professional experimental test auxiliary instrument, the cooling and heating circulation device for lithium battery testing is the circulating supply end of the cold source and the heat source, with a wide operating range. It is used in pharmaceutical, chemical, biological, etc., to provide heat and cold sources for reactors, tanks, etc., and can also be used for heating and cooling of other equipment. The temperature control range is wide, the heat transfer medium does not need to be replaced in the whole process, and the heat transfer medium consumption is low. The normal installation and use of the lithium battery test cooling and heating cycle device in the handling of problems will directly affect the performance and service life of the instrument.
In the high temperature experiment, if the temperature change does not reach the experimental temperature value, you can check the electrical system and check the problem one by one. If the temperature rises very slowly, check the air circulation system to see if the regulating baffle of the air circulation is open normally; otherwise, check if the motor operation of the air circulation is normal. If the temperature overshoot is severe, then you need to adjust the PID parameter settings. If the temperature rises directly and the maintenance is over-temperature, then the controller has a problem and the controller must be replaced.
The low temperature does not reach the goal of the experiment. Observe whether the temperature changes slowly, or whether the temperature has a rising trend after reaching a certain value. The former is to check whether the work room is dried before the low temperature experiment, and then the experiment samples are put into the work room after the experiment is done after the work room is kept dry. Are there too many experimental samples in the operation room, so that the wind in the operation room cannot circulate adequately? After removing the above reasons, it is necessary to consider whether it is a fault in the refrigeration system. In this way, it is necessary to ask the manufacturer's professional staff to perform maintenance. The latter phenomenon is caused by the poor operating environment of the equipment. The ambient temperature and location (the distance between the back of the box and the wall) of the equipment must meet the requirements (there are rules in the equipment operation instructions).
When there is a problem with the cooling and heating circulation device for the lithium battery test suddenly during the experimental operation, the corresponding fault display prompt and an audible alarm prompt will appear on the control instrument. The operator can quickly check which category it belongs to in the chapter on the fault removal in the operation of the equipment, and then ask professionals to quickly remove the fault to ensure the normal progress of the experiment. There will be other phenomena in the use of other environmental laboratory equipment, so specific phenomena must be analyzed and eliminated.
