    The softening of the natural aging elastic gasket of the titanium plate heat exchanger is related to pressure and temperature. When the gasket loses its elasticity, the heat exchanger will drip. In some products, in order to cope with leakage caused by aging. Phenomenon, the sealing function of the titanium plate heat exchanger should be adjusted, that is, the bolts of the combined plate heat exchanger should be tightened again.

    Adjust the pressing force of the elastic gasket between the heat exchangers to solve the dripping problem. On the nameplate of a titanium plate heat exchanger with this function, the maximum and minimum stresses are usually given. For new heat exchanger chipsets, the minimum allowable stress should be used to fix the joints.

    During use, it will often simply break the sealing gasket, and then gradually weaken the function of our plate heat exchanger. What is the cause of sealing gasket failure? Common problems are mainly the impact of stress and timing. Practical impact: After the device is used or placed for several years, the aging of the sealing material itself may affect the sealing effect, so a new sealing pad should be used for inspection in time.

    Effect of pressure: The plate heat exchanger can be disassembled and used for a period of time under additional pressure to cause leakage. In addition to the quality problems of the equipment during installation and installation, there are usually abnormal shock loads in the system. Related to this, ordinary employees cannot see it, and it is not easy to check. This impact causes the pressure peak to be about 2 times higher than the normal working pressure. It is the banana washing machine that moves in the plate heat exchanger. The seal failed.
