Why plate heat exchanger seals fail
The softening of natural aging elastic gaskets of titanium plate heat exchangers is related to pressure and temperature. When the gasket loses its elasticity, the heat exchanger will drip. In some products, to deal 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 chip sets, the joint should be secured with the minimum allowable stress.
In the course of use, the sealing gasket is often simply destroyed, and then the function of our plate heat exchanger is gradually weakened. What is the cause of the gasket failure? Common problems are mainly the effects of stress and timing. Actual impact: After the equipment has been used or left for several years, the aging of the sealing material itself may affect the sealing effect, so a new gasket 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 of the equipment during installation and installation, there are usually abnormal shock loads in the system. Related to this, ordinary employees cannot see and are not easy to check. This shock results in pressure peaks that are usually about 2 times higher than normal working pressure. It is the banana washing machine that moves inside the plate heat exchanger. It is the seal failure.
