Xiao Bian recently collected some data on the maintenance of plate heat exchangers and integrated the most prone failures of plate heat exchangers. Today, Xiao Bian gave you a brief introduction of the most common and most probable occurrences of plate heat exchangers. A few faults:
In all faulty plate heat exchangers, the leakage phenomenon is the most common, because the plate heat exchanger belongs to the pressure vessel, so the requirement for the sealing is very high, no matter the heat exchanger plate heat exchanger Pieces or sealing gaskets, even if the tube plate welding port will not leak well, but once there is an external leakage, plate heat exchanger is destined to not function properly.
The occurrence of string liquid is also one of the more common failures. The phenomenon that it manifests is that the two media are mixed inside the heat exchanger, and then it will cause abnormal pressure and temperature phenomena. If the medium is a special chemical liquid, even It may also cause accidents, so the problem of string heat exchangers can not be overlooked.
Plate heat exchangers can not meet the operating conditions of the temperature requirements, such as heat exchanger heat exchangers are inefficient, inadequate heating and so on. However, there are many reasons for this consequence, such as some design deficiencies or improper operation personnel, or the failure of the plate heat exchanger itself, so we need to step by step for troubleshooting. Now.
