How Should We Properly Maintain The Cryogenic Bath?

First, the water circulation in the low temperature constant temperature water tank is normal for more than one year. However, the cooling speed seems to be getting slower and slower. The higher the temperature is, the more obvious it is. Reasons for the cryostat:

     Water recycling is simple, but regular maintenance work cannot be ignored. There are a lot of seemingly faulty problems that are caused by not doing regular maintenance. The electric power of the water cycle itself and the heat taken away by the refrigerant from the load need to be removed from the radiator at the front hood. If the front hood is filled with dust and cotton wool, it will hinder the heat dissipation, and the cooling effect will be Great discount. Generally, the decrease in cooling capacity under normal use conditions is caused by poor ventilation or high ambient temperature.

     Second, the water circulation in the low temperature constant temperature water tank is normal before use, but now the noise is much larger than before. What is the reason?

    Reasons for the cryostat: As mentioned above, the daily maintenance of the water cycle is also related to this problem. Everyone knows that there is a small amount of impurities in the water, that is, after the distilled water is added to the water tank, it is impossible to completely guarantee that there is no impurity at all. For the water cycle, the general temperature is set at 20 ° C, which is especially suitable for the growth and reproduction of microorganisms. After a long time, these microorganisms will block the filter of the waterway, causing poor water return and the pump will have a large noise. Sometimes these microorganisms are attached to the surface of the heat exchanger, causing the heat transfer effect of the heat exchanger to be deteriorated and the cooling capacity to be small.

    Therefore, it is necessary to strictly follow the requirements in the manual to do the routine maintenance of the cryostat, regularly clean the inner tank, and stop it for a long time to keep the tank dry. There seems to be a leak in the water cycle. Sometimes there are a few drops on the ground. Is there a leak on the waterway? Generally speaking, there is no leakage in the waterway during normal use. When the relative humidity in the high ambient air is too large, the water pump, the water pipe joint, and the external water pipe in the water circuit of the water circulation are likely to condense dew. After accumulating more, it will drip onto the ground, and there is no need to worry that there is water in the waterway. The place where the water leaks. If you are concerned about this, turn on the air conditioner to lower the room temperature or dehumidify to avoid dew.
