Solution to abnormal temperature and humidity in constant temperature and humidity test chamber
Constant temperature and humidity chambers are generally capable of high temperature, low temperature, damp heat and other tests. During the constant temperature and humidity machine test, various temperature and humidity failures can be handled by the user according to the following methods. 1. In the high temperature test, if the temperature change does not reach the test temperature value, you can check the electrical system to eliminate the fault one by one. If the temperature rises very slowly, it is necessary to check the wind circulation system to see if the adjustment baffle of the wind circulation is opened normally, otherwise, check whether the motor of the wind circulation is operating normally. If the temperature overshoot is severe, then the PID setting parameters need to be adjusted. If the temperature rises directly and the over-temperature protection, then the controller fails, the control instrument must be replaced. 2. The low temperature can not reach the test index, then you should observe the temperature change, whether the temperature drops slowly, or the temperature has a tendency to rise after the temperature reaches a certain value, the former should check whether the temperature Drying in the studio, keep the studio dry, and then put the test samples into the work room for testing. Whether the test samples in the work room are placed too much, the wind in the work room cannot be fully circulated. It is necessary to consider whether it is a fault in the refrigeration system. In this case, the professional personnel of the manufacturer must be repaired. The latter phenomenon is caused by the poor use environment of the equipment. The ambient temperature of the equipment and the location (the distance between the back of the box and the wall) must meet the requirements (as specified in the equipment operation instructions). console table modern,table console,hallway console table,console tables living room furniture Kumusi (Dongguan) Furniture Co., Ltd. , https://www.kcoffeetable.com
