In the usual test process, many people will encounter such a problem: high and low temperature test chambers are not used for a long time, how to carry out maintenance? The following small series for everyone to support it.
(1) First wipe the high and low temperature test chamber clean with a clean cloth. Before using it again, the first thing you need to do is to open the high and low temperature test chamber door ventilation and wipe the inside of the high and low temperature test chamber again. It is best to clean the dust on the condenser to facilitate heat dissipation after the high and low temperature test chambers are working.
(2) For system maintenance, be sure to unplug the power supply. When the power is off, it is best to prevent damage to the compressor and other components when the high and low temperature test chambers are shut down.
(3) Before re-use, clean the high and low temperature test chambers. Do not start using them immediately. It is best to let the high and low temperature test chambers run for a short time. Stop after a period of two or three minutes, and repeat this several times. Why do you want to do this? We know that the lubricating oil is fluid. When the high and low temperature test chamber is left for a period of time, it will cause the local mechanical parts to be too thin. When used again, because the internal temperature of the high and low temperature chamber is room temperature, Lowering the rated temperature requires continuous operation of the compressor for a long time. At this time, the excessively thin portion of the lubricating oil will wear rapidly, thereby reducing the life of the high and low temperature test chamber.
(4) Allowing the high and low temperature test chamber to run for a short time, the lubricant can be redistributed in the compressor, and the inside of the machine can be immersed through the intermittent time. Here, by the way, many of the newly purchased high and low temperature test chambers have been put on hold for a period of time in the laboratory. This method can also be used to maintain the high and low temperature test chambers in the first use to prevent the compressor from losing life.
