The manufacturer of the plate heat exchanger reminds you that the plate heat exchanger should not be in a hurry even if it is leaking. The above measures can give you guidance, but it should be noted that if it is not specifically understood, try not to disassemble it yourself, so as to minimize the risk.
Sometimes, the plate heat exchanger leakage (PHE) will fail when the plate has small cracks, or in a few cases, when the gasket is displaced or damaged. This situation is particularly harmful to the food, beverage and chemical industries, and will cause serious shutdown. Fortunately, PHE is modular. Once a defective plate or gasket is found, as long as it is separated from the adjacent plate, PHE can be put into use again, and its capacity will be slightly reduced until the replacement is completed. How to find the defective plate? The manufacturer of plate heat exchanger offers you the following suggestions. Let's get to know!
The manufacturer of plate heat exchanger has listed four simple steps for you. Step 1: drain, isolate and dry. First, evacuate the PHE and isolate it from the system. The actual test depends on the water, so you must wait for all the boards to dry. You can decompose it now to speed up the process, but you must reassemble it to the next step, and then decompose it again in the next step.
Step 2: moisture test. Second, let the water flow through only one side of the PHE. Each board will have wet edges and dry edges, but both sides of the leaking board and the adjacent board will have wet edges, so it is easy to recognize by touch.
Step 3: Disassembly. Third, remove the plate heat exchanger according to the instructions of the plate heat exchanger manufacturer. In this step, it is better to put the boards in the frame, so that you can check them one by one more easily.
Step 4: Check. Finally, look at each plate separately and notice that both sides are wet. Remove all the wet plates on both sides, and then reassemble the PHE, so that the capacity can be reduced until there are suitable replacement parts.
The manufacturer of the plate heat exchanger reminds you that the plate heat exchanger should not be in a hurry even if it is leaking. The above measures can give you guidance, but it should be noted that if it is not specifically understood, try not to disassemble it yourself, so as to minimize the risk.
