The composition of the plate heat exchanger is a kind of heat exchanger equipment with high efficiency, which is a stack of corrugated metal sheets. The heat dissipation of the plate heat exchanger is achieved through the rectangular channels between the various plates to achieve the purpose of heat exchange. We know that the heat transfer efficiency of the plate heat exchanger is relatively high, the structure is relatively simple, and the area is small, so this is one of the reasons why people are enthusiastic about plate heat exchangers. Plate heat exchanger manufacturers have done research on the heat transfer coefficient of plate heat exchangers to about three times that of tube heat exchangers at the same pressure.
In order to maintain the normal working efficiency of the plate heat exchanger, we must not only operate it in accordance with certain operating regulations, but also perform regular maintenance work on it. Recently, users of plate heat exchangers always report a problem is how to deal with sudden shutdown during the use of plate heat exchangers. Let us analyze how to deal with this problem.
First, if the plate heat exchanger is shut down during normal use, we must first turn off the pump of the equipment, and then disconnect the power supply. If the plate heat exchanger suddenly stops due to a fault during use, it should be cut off in time to check the cause and solve it in time.
Second, if a vent valve has been installed on the plate heat exchanger, it needs to be opened at this time.
3. In the case of a sudden shutdown of the plate heat exchanger, we need to close all the hot and cold inlet valves of the equipment, and then close the two outlet valves.
4. If it is a medium that is corrosive to high temperature, we should avoid scalding of the equipment.
The above is what we should do when the plate heat exchanger is shut down. If we really encounter such a problem during actual use, we must find a professional person to solve it in order to avoid the normal use of the equipment in the later period problem.
