Replacing the gasket of the plate heat exchanger is not a very simple matter. Usually, if the operation method is not appropriate, the problems of leakage and liquid stringing of the plate heat exchanger will appear. Today we will introduce the heat exchanger to everyone. Matters needing attention when replacing gaskets.

Each heat exchanger plate is coated with a fluorescent test agent. Check for small cracks and eroded holes under ultraviolet light. And clean again. Also. It is also important to check the condition of the sealing groove. Repair if necessary.

Check and repair the bonding position and bonding quality of each plate fin. Sort by installation order. Then carefully assemble the plate fins.

After the plate heat exchanger is chemically cleaned. Use a high-pressure blowing device to remove the chemical media remaining on the surface of the plate heat exchanger.

Maintenance and inspection of reuse function. Inspect the wall thickness of the heat exchanger and piping when rust is suspected.

Remove aging seals on plate heat exchangers. According to different dirt. The acid-base cleaning tank is used for chemical cleaning. The surface of the parts to be cleaned will not be attacked by chemical media.

Temporary treatment method for sealing gasket aging of plate heat exchanger

Temporary treatment method for the aging of the gasket of the plate heat exchanger: The softening of the elastic gasket is related to pressure and temperature. When the gasket loses its elasticity, the plate heat exchanger will drip. In some products, in order to solve the leakage caused by the aging of the gasket, the sealing function of the heat exchanger should be adjusted, that is, the bolts of the combined plate heat exchanger should be tightened again to adjust the elastic gasket between each heat exchanger To solve the problem of dripping.

On the nameplate of a plate heat exchanger with this function, it generally gives the promise of large stress and small stress. For the new plate heat exchanger chip group, the connection stress
