The internal leakage of the plate heat exchanger is generally not easy to find in time. The way to find this leakage is to test the medium on the low pressure side frequently. Below we will introduce the shutdown inspection of the internal leakage of the plate heat exchanger in detail. method.

1. Disassemble the heat exchanger, remove the dirt on the surface of the plate, dry it and reassemble the heat exchanger. A hydrostatic test with a pressure of 0.2~0.3Mpa is carried out on one side. Stop the test after water flows out from the other side, open the heat exchanger, and carefully observe the untested side of the plate, among which the wet plate is the plate with holes or cracks.

2. Light transmission and coloring inspection methods can also be used on site to detect waste boards.

3. All waste boards and gaskets that are checked out must be replaced and used after reassembly.

The above is the method of shutting down and checking the internal leakage of the plate heat exchanger. After understanding these, if you encounter this kind of problem again, you can deal with it in time to avoid long-term delays in work efficiency due to equipment failure.
