Plate heat exchangers can only play their role under good sealing conditions. Therefore, in order to have better sealing performance and prevent leakage problems, seals are generally installed for it.
1. The working mode of the plate heat exchanger is continuous or discontinuous.
2. The corrosiveness of the heat dissipation medium and the cleaning agent used.
3. Working temperature.
4. Work pressure.
5. Due to excessive pressure and uneven pressure, the stress of the elastic gasket is relatively large.
6. Natural aging.
7. The softening of the elastic gasket is related to pressure and temperature. When the gasket loses its elasticity, dripping will occur. In order to solve the dripping phenomenon caused by the aging of the gasket, the sealing performance of the heat exchanger can be adjusted, that is, tighten the combination again. The bolts of the plate heat exchanger adjust the pressing force of the elastic sealing gasket between each heat exchanger to solve the problem of dripping.
