Make corresponding preparations before replacing the rubber pads of the brand plate heat exchanger
460 plate heat exchangers are currently widely used in all walks of life. Many users may find that the sealing gasket fails during the use of this equipment. At this time, it is necessary to replace the sealing gasket in time to avoid affecting the effect of the equipment. . So, what preparations should we make before replacing the rubber pads of the brand plate heat exchanger? What problems should be paid attention to when replacing? Let's briefly understand: Before replacing the gasket, do the following tasks: Before removing the old gasket, write down the flow pattern formed by the gasket on the heat exchange plate. Sealing gaskets must be installed on the No. 1 plate that is in contact with the fixed compression plate or the partition (S), so that when the plate is installed on the plate frame, there are gaskets in each gasket groove. The two sealing gaskets must be cut, and the sealing gasket on the fixed compression plate or the isolation plate should be separated from the ring part on the 'a' corner. Note: If the four connecting pipes are all set on the fixed compression plate, there is generally no need to replace the sealing gasket, because its function is only to fill the gasket groove, so as to damage other plates in the compression plate bundle. After the preparation work is completed, open for replacement, detailed steps: as long as the buckle is broken apart as required, and the gasket can be removed, avoiding the buckle from breaking during the operation. Plate heat exchanger rubber gasket cleaning: the new gasket and the gasket groove of the new plate should be wiped clean with a cloth soaked with degreasing agent. As a degreasing agent, a certain solvent can be used, which can effectively remove grease. The following solvents can be used as examples: trichloroethylene, chlorothene VG, acetone, methyl ethyl ketone or ethyl acetate. Before applying glue, the solvent must be allowed to evaporate clean. this point is very important. Generally, it is recommended to use fine sandpaper to clean the bonding surface of the sealing end piece at 20 degrees Celsius, instead of cleaning with a degreaser. The above are some preparations that users need to do before replacing the rubber pads of the brand plate heat exchanger. I hope it will be helpful to you.
