. The following is a detailed analysis of the maintenance of lithium bromide units:
I. Importance of Maintenance
During prolonged operation, lithium bromide units are affected by various factors such as changes in water quality, wear, and corrosion, which can lead to performance degradation or even malfunctions. Therefore, regular maintenance helps identify and address these issues in a timely manner, ensuring the safe and efficient operation of the units.
II. Main Content of Maintenance
‌Cooling Water System Maintenance‌
Regularly inspect the water quality of the cooling water, including indicators such as pH value, conductivity, hardness, and microbial content, to ensure it meets the operational requirements of the unit.
Periodically clean the cooling water system to remove impurities like scale and rust residue, preventing blockages in the heat exchange tubes.
Add corrosion inhibitors, scale inhibitors, and biocides as needed based on water quality to prevent corrosion, scaling, and microbial growth.
‌Unit Body Inspection‌
Check the vacuum level of the unit to ensure it remains below 10mmHg for stable operation.
Inspect the connections of various components to ensure there are no leaks.
Check whether the refrigerant water bypass valve is closed to prevent non-condensable gases from entering the unit.
‌Electrical System Inspection‌
Inspect the connections and wear of electrical components to ensure the electrical system operates normally.
Check for abnormal alarms in devices such as frequency converters and electric regulating valves, and address them promptly.
Verify the insulation to ground of all pumps in the unit to ensure electrical safety.
‌Refrigerant System Inspection‌
Check the refrigerant pressure and temperature to ensure they are within the normal range.
Regularly inspect the sealing of the refrigerant system to prevent refrigerant leaks.
‌Regular Maintenance and Overhaul‌
Perform routine maintenance on the unit, including cleaning, lubrication, and replacement of parts.
Conduct periodic inspections to assess the operating status of key components such as condensers, evaporators, and compressors.
III. Precautions for Maintenance
‌Safety‌
Ensure the power is cut off and the unit is in a shutdown state before performing maintenance work.
Wear appropriate protective gear to prevent accidental injuries.
‌Operation‌
Maintenance work should be carried out by qualified personnel to ensure standardized and accurate operations.
Follow the unit’s user manual and maintenance guide for all procedures.
‌Complete Documentation‌
Keep detailed records of the maintenance process, including inspection results, actions taken, and replaced parts.
Establish a maintenance archive to facilitate tracking of the unit’s operating condition and maintenance history.
‌Timely Repairs‌

Address any identified issues promptly to prevent them from escalating.
For problems beyond handling, contact professional maintenance personnel in a timely manner.
In summary, the maintenance of lithium bromide units involves multiple aspects and requires comprehensive and meticulous execution. Through regular maintenance, the safe and efficient operation of the units can be ensured, extending their service life.
