          Notes on the life of rubber gaskets for plate heat exchangers
          Release time: 2019/11/29 11:28:09
          The heat exchange of the plate heat exchanger is not only performed in the narrow space between the plates, but also occurs in many gaskets between the plates, so the gaskets are an important part. The life of the rubber gasket of the plate heat exchanger can be described as follows:
          When the gasket is installed on the plate and compressed to the nominal size after assembly, the initial sealing stress occurs, and the stress relaxation of the rubber gasket begins. During the period of transportation, storage and installation of the plate heat exchanger, the temperature of heat exchange is lower and the stress relaxation is relatively mild. After driving, the temperature started to rise and the stress relaxation gradually became serious. After the board changer has been running for a certain period of time, it needs to be stopped for maintenance and cleaning, and the board changer cools down to its original temperature. At this time, the seal stress is lower than the initial seal stress, but it is usually still above the minimum stress of the seal. Still sealed.
          After restarting the car, seal stress and stress relaxation resumed. After several repetitions, under the condition of cold and heat exchange, the sealing stress of the rubber gasket will be reduced below the minimum sealing stress of the holding seal, the plate heat exchanger will begin to leak, and it will be forced to stop operation and renew the rubber gasket.
          Through the above information, you should be able to understand that rubber gaskets are important parts of plate heat exchangers. Selecting suitable products can ensure the long-term operation of the plate changer. As for how to choose, experience and a lot of experiments can give the answer.
