Plate heat exchanger: Precautions for maintenance of heating plate heat exchanger

When repairing the heating plate heat exchanger, first remove the pressure on the equipment, then start to find the problem and try to repair it.
Today, the plate heat exchanger manufacturer will introduce the precautions for the maintenance of the heating plate heat exchanger. Let's take a look!
If the heating plate heat exchanger has problems in cold weather, the maintenance enterprises should keep up with the pace; Two days ago, a customer came to us and said that they had bought a heating plate heat exchanger from another home. There was a point of water leakage. They wanted our technical management personnel to repair it to avoid further leakage.
In addition, our two plate heat exchangers are running in parallel. The worst thing is that they only run these two plates and prevent leakage. Although the pressure requirements for the two heating plate heat exchangers in operation are relatively high, our experimental pressure is more than 1.3 times the design pressure. If you can find the problem, it is relatively easy to solve it. It is important to note that the pressure work needs to be closed in order to "start" on the heat exchanger. This is what the editor said to pay attention to, but a non-professional technician may see the leakage and want to see whether the gasket is aging or misaligned or other problems, but the pressure at this time is the working pressure. Once the pressure is the working pressure, the pressure will leak out from this point, which will lead to greater leakage. At that time, it may change from a small problem of gasket to a problem of plate deformation and gasket sealing, and the plate and gasket need to be replaced. That's not a matter of days.
When repairing the heating plate heat exchanger, first remove the pressure on the equipment, then start to find the problem and try to repair it.
The above is the precautions for you when repairing the heating plate heat exchanger. I hope it can help you!
