The use of gasketed plate and frame heat exchangers is not only affected by light and climate, but also by the surrounding environment. So, the editor below will talk to you about the factors that affect the service life of the gaskets of the sealed plate and frame heat exchanger.

1. The influence of the location of the heat exchanger
The use of gasketed plate and frame heat exchanger is not only affected by light and climate, but also by the surrounding environment. Therefore, compared with the indoor heat exchanger, the service life of the sealing ring will be different. In order to reduce the environmental impact, it is very effective to use a protective cover or insulating layer on the outside of the plate heat exchanger.
2. The influence of heat exchanger size
The gasketed plate and frame heat exchanger is composed of a fixed cover plate, a movable cover plate and a set of plates. The principle of its structure is to press this group of plates between the front and rear end plates with the help of a screw, so that the necessary pressure to the sealing ring can also be generated. Based on this structure of the heat exchanger, during the process of pressing the heat exchanger, the moving cover is continuously pressed closer to the fixed cover, causing the plates near the moving cover to be squeezed first. The more plates that need to be compressed, the greater the pre-stress generated. Due to this structural feature, under the same working conditions, the number of plates will also affect the service life of the heat exchanger sealing ring.
3. The influence of working conditions
The service life of the sealing ring largely depends on the degree of stress experienced during its use. The stress here refers to the mechanical stress generated under thermal and chemical loads. During operation, these stresses are either generated by the necessary compression and pressure shock, or by the expansion of the gasket material under certain limited conditions. Therefore, under high temperature and high pressure operating conditions, the aging process of the sealing ring will accelerate.
4. The influence of the flowing medium in the heat exchanger
The medium flowing through the gasketed plate and frame heat exchanger has the greatest impact on the life of the sealing ring. Regarding how to choose a suitable sealing ring, it is often not perfect in consideration of fluid substances and use conditions. Therefore, in many processes, the sealing ring of the heat exchanger will be corroded by some cleaning fluid, mainly because this factor is not considered when selecting the sealing material.
Although all the gasketed plate and frame heat exchangers are optimized for practical applications, the mixing of cooling, heating additives, inhibitors and other substances is often neglected in the design process, and these substances tend to penetrate into the seal The ring thus causes damage to its physical properties.
