Maintenance of spiral wound heat exchangers

Spiral wound heat exchanger is a common heat exchange equipment widely used in many industrial fields. In order to ensure the normal operation and prolong the service life of the spiral wound heat exchanger, maintenance work is very important. When performing maintenance on spiral wound heat exchangers, we need to pay attention to the following key points.

Firstly, it is necessary to regularly inspect and clean the spiral wound heat exchanger. As the working environment of spiral wound heat exchangers is usually harsh, such as water containing a large amount of suspended solids, sediments, algae and other impurities, these impurities can adhere to the surface of the heat exchanger and seriously affect its heat transfer efficiency. Therefore, it is necessary to regularly inspect and clean the spiral wound heat exchanger. Chemical or mechanical cleaning methods can be used to remove impurities completely.

Secondly, check the sealing performance of the spiral wound heat exchanger. There are many sealing points inside the spiral wound heat exchanger, such as pipe cover sealing, pipe interface sealing, etc. If there is leakage or liquid leakage at these sealing points, it can lead to a decrease in the efficiency of the heat exchanger or even prevent it from working properly. Therefore, it is important to regularly check the sealing performance of these sealing points and replace the seals if necessary.

Thirdly, pay attention to the anti-corrosion work of spiral wound heat exchangers. Spiral wound heat exchangers are usually made of metal and are easily affected by corrosion. There may be corrosive media such as acid, alkali, salt, etc. in the working environment, which can directly affect the service life of the heat exchanger.Therefore, when installing spiral wound heat exchangers, we need to perform anti-corrosion treatment on them, such as coating or using anti-corrosion materials.

Finally, make reasonable use of spiral wound heat exchangers. The service life and operational effectiveness of spiral wound heat exchangers are also related to the user's operating methods. Reasonable use of heat exchangers, such as avoiding overload operation and sudden shutdown, can extend the service life of heat exchangers. At the same time, we also need to implement a reasonable maintenance plan for the spiral wound heat exchanger, regularly inspect and maintain it to ensure its normal operation.
