The Temperature Of The Plate Heat Exchanger Does Not Meet The Requirements

The plate heat exchanger is a high-efficiency heat exchanger made up of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. The temperature of the plate heat exchanger does not meet the requirementsThe heating temperature of the plate heat exchanger cannot meet certain requirements. Please check whether the outlet temperature is too low and fails to meet the planning requirements. For external leakage, check the seal between the plate and the plate, the second seal leakage inspection groove of the plate, and the inner side of the end plate and the compression plate.

(1) The pressure drop of the heat exchanger is large. The pressure drop at the inlet and outlet of the medium exceeds the planning requirements, or even many times higher than the planned value, which seriously affects the system's requirements for flow and temperature. In the heating system, if the pressure drop on the hot side is too large, the primary side flow will be seriously insufficient. That is, the heat source is not good, resulting in the secondary side outlet temperature can not meet the requirements.

(2) Internal leakage of the plate heat exchanger. The main feature is that the medium on the higher pressure side is strung into the medium on the lower pressure side, and abnormal pressure and temperature will appear in the system. If the medium is corrosive, it may also cause corrosion of other equipment in the pipeline. Plate heat exchanger plates are independent components, which can be increased or decreased in accordance with certain requirements, and are suitable for various process requirements.
