The plate heat exchanger exchanges the temperature of the hot water or the waste hot water with the normal temperature water, and heats the normal temperature water for production or domestic heating use.The heat exchanged by the heat can be fully utilized, energy saving and environmental protection. What problems are easily caused by the plate heat exchanger?
(1) Blockage problem
When the heat exchanger is working, the pressure loss at the outlet increases, and the front and rear pressure parameters exceed 0.1MP, which may indicate that the heat exchanger may be clogged. At this time, it is necessary to stop the operation and clean and remove the debris.
(2) The gas inside the heat exchanger is not discharged
When the installation is completed for the first time, it is necessary to pay attention to whether there is a large amount of air inside. This is to check the exhaust system and perform the formal operation after the air is exhausted.
(3) There is a problem with the water quality in the system, and the internal heat exchanger is fouled.In the face of this situation, the first method is to shut down the machine and disassemble it for cleaning. The other is chemical cleaning.
(4) Heat exchanger leakage
If the heat exchanger leaks, the pressures before and after will be the same, indicating that the heat exchanger is internal leaking. It is necessary to replace the plate in time for internal leakage; it is necessary to replace the gasket after leaking outside.
