What points should be paid attention to when choosing plate heat exchanger gaskets
Author:
When choosing, consider the following:
1. Expansion: The raw material of the plate heat exchanger gasket is generally plastic material. When the extrusion deformation subsides, it can be restored to its original appearance. In other words, the volume of the gasket will not change during the whole process of shrinking the gasket. size is indicated.
2. Compressive strength: It should have sufficient compressive strength to enable it to enter the pressing force of the sealed state and withstand high fluid media.
3. Ductility: It can not only meet the specified application compressive strength, but also have ductility, so that the gasket of the plate heat exchanger can closely meet the plate under sufficient working pressure to achieve sealing performance.
4. Water permeability resistance: that is, the performance of medium resistance, which can resist the infiltration of different media.
5. Temperature resistance: When purchasing, we must master the temperature area of the gasket of the plate heat exchanger, and choose the gasket with the appropriate temperature specification according to the temperature requirements of its application, or according to the needs of the working conditions to avoid Its service life is affected.
