Chiller water system

The chiller continues to operate, and the working status of the chiller directly affects the volatilization of liquid helium and the normal operation of the nuclear magnetic resonance, so it is very important to ensure the normal operation of the chiller. When the chiller fails, the heat cannot be dissipated when the magnetic resonance is working internally, and liquid helium cannot guarantee such a low temperature. At this time, the magnetic resonance will definitely not be able to work normally, so the chiller is very important to the magnetic resonance system. It is very important to ensure the normal operation of the chiller.
Chiller water system
Regular maintenance and upkeep of the chiller is required during use. The entire chiller system is divided into a refrigeration system and a water system.
Maintenance and maintenance of the refrigeration system
Clean the condenser regularly
Check the pressure. If the pressure does not reach the normal value, you must add coolant
Check whether there are any debris around and on the machine. materials and clean the heat sink regularly to avoid failure of the chiller fan to dissipate heat, resulting in chiller failure.
Water system maintenance and upkeep
Check whether the water in the system reaches normal pressure. If the pressure does not reach normal value, add water if it is lower than normal value, and release water if it is higher than normal value.
The filter must be cleaned regularly to prevent dirt from flowing into the magnetic resonance cold head compressor, causing poor heat dissipation.
