Installation essentials of heat exchanger plates for plate heat exchangers
After a period of service life, the plate heat exchanger will appear fouling. Especially in the plate heat exchanger that exchanges heat between water and water, steam and water, cold water will produce some calcium and magnesium after being heated by high temperature. The ions are then attached to the surface of the heat exchanger plates. If things go on like this, it will reduce the heat transfer efficiency of the heat exchanger plates and affect the heat exchange efficiency of the plate heat exchanger.
At this time, we need to clean the heat exchanger plates, but we need to remove the heat exchanger plates during cleaning, so we must install them correctly after cleaning the heat exchanger plates:
1. The steps to install the plates of the plate heat exchanger are very important. Because it is necessary to check the damage of the plates and heat exchanger gaskets during the installation process, it must be checked that a heat exchanger gasket is correctly installed on each heat exchanger plate. If the inspection and replacement of the heat exchanger gasket is neglected, it will cause the plate heat exchanger to leak during the pressure test operation, and rework will waste time and labor, and may even delay the use of the heat exchanger.
2. There are more than 160 heat exchanger plates on each plate heat exchanger. On the basis of checking the heat exchanger gaskets, multiple people cooperate to install each heat exchanger plate to ensure the heat exchanger plate Installed in the correct position and does not leak.
