In the process of daily experimental operation, many people will encounter this kind of problem: how to carry out maintenance if the high and low temperature box is not used for a long time?

(1) First clean the inside of the high and low temperature box with a clean cloth. Before using it again, the first thing you should do is to open the door of the high and low temperature box for natural ventilation, and at the same time scrub the inside of the high and low temperature box again. Dust, in order to facilitate the heat removal of the high and low temperature box after working.

(2) For system maintenance, be sure to unplug the switching power supply. When the power is turned off, when the high and low temperature box is turned off, avoid damage to the compressor and other components.

(3) Before re-application, after cleaning the high and low temperature box, do not apply it gradually, let the high and low temperature box operate for a short period of time, and stop for a period of time after every 23 minutes of operation. ?We know that the grease has fluidity. When the high and low temperature box is placed for a period of time, the grease will be too thin for some parts. When it is applied again, because the internal temperature of the high and low temperature box is the room temperature, it will drop to the rated temperature. Then the compressor must run continuously for a long time, and the part of the grease that is too thin at this moment will be damaged rapidly, thereby reducing the service life of the high and low temperature box.

(4) Let the high and low temperature box operate for many times in a short period of time, so that the grease can be distributed in the compressor again, and infiltrate the inside of the parts according to the interruption time. Here, it should be mentioned by the way that many newly bought high and low temperature boxes are in the laboratory. It has been idle for a period of time, and these methods can also be used to maintain the high and low temperature box when it is used for the first time, so as to avoid reducing the service life of the compressor.
