How should heat exchanger maintenance be performed?

Heat exchangers are common equipment in industrial production. In order to ensure their normal operation, regular maintenance work is required. Here are some maintenance methods for heat exchangers.

Clean pipes

Regular pipe cleaning is key to keeping your heat exchanger operating properly. If the pipes are blocked, the efficiency of the heat exchanger will decrease or even fail to work properly. Pipe cleaning can use high-pressure water or professional cleaning equipment.

Check tightness

The sealing of the heat exchanger is an important guarantee for its normal operation. Regularly check the status of seals, such as gaskets, sealing rings, etc. If damage or aging is found, replace them in time. At the same time, check for leaks. If leaks are found, the cause needs to be investigated and repaired promptly.

Check structure

Regularly check whether the structure of the heat exchanger is intact. If it is deformed, damaged, loose, etc., repair or replace it in time. In addition, pay attention to check the condition of the welds. If there are cracks, fatigue and other problems, they need to be repaired or replaced.

Replace cooling water

The cooling water used in the heat exchanger needs to be replaced regularly to ensure its quality and performance. At the same time, attention should also be paid to the quality of the cooling water, such as pH value, hardness and other indicators, which must be within a reasonable range. If the water quality is not up to standard, it needs to be replaced or adjusted in time.

Check accessory equipment

Ancillary equipment of the heat exchanger, such as pumps, valves, etc., also need to be inspected regularly to ensure their normal operation. If any abnormality is found, it needs to be repaired or replaced in time.

Clean heat exchange plates

During use, the heat exchange plate is easily affected by dirt, rust, etc., resulting in a decrease in its heat exchange efficiency. Therefore, the heat exchange plates need to be cleaned regularly. When cleaning, you can use chemical cleaning agents or high-pressure water for cleaning.

Check heat media

The heating medium used in the heat exchanger needs to be inspected regularly to ensure its quality and performance. If the heating medium is found to be turbid, smelly, discolored, etc., it needs to be replaced in time. After reading the above content, everyone should know that regular maintenance is an important guarantee for the normal operation of the heat exchanger. During maintenance, attention should be paid to details, and problems should be discovered and dealt with in time to extend the service life of the heat exchanger and ensure its performance and efficiency.
