Plate heat exchanger maintenance: What should I pay attention to when operating a plate heat exchanger? _
426 plate heat exchanger plates are closely arranged. Compared with other heat exchanger types, the plate heat exchanger occupies less area and space. Today, the editor shared with you the maintenance of the plate heat exchanger: operation What should I pay attention to when using plate heat exchangers? 1. Always check all the sealing surfaces and welds of the heat exchanger to observe whether there are any abnormal phenomena such as leakage. If leakage is found, mark the leakage point in time and deal with it after shutdown. 2. Check the pressure gauge and thermometer regularly to observe whether there is any abnormality. 3. When stopping, first slowly close the inlet valves of the hot and cold media, and then close the outlet valves of the two media. When the machine is turned on, the opposite is true, first open the outlet valve, and then slowly open the inlet valve. 4. The low-pressure side medium should be tested regularly to avoid mixing of high-pressure side medium. If it is mixed in, it indicates that internal leakage has occurred and should be stopped for processing.
