4 of the most common fault of plate heat exchanger
Use the 4 most common faults of plate heat exchanger:
1 external leakage: the main performance for the leakage (volume is not, water droplets are not continuous) and leakage (a larger amount of water droplets). The main parts of the external leakage are the seal between the plate and the plate, the two seal leakage groove parts of the plate and the side of the end plate and the inner side of the pressing plate.
Heat exchanger fouling
2 series of liquid: the main features of the high pressure side of the media into the lower side of the pressure side of the medium, the system will appear in the pressure and temperature anomalies. If the medium is corrosive, it may also lead to corrosion of other equipment in the pipeline. The fluid is usually located in the diversion area or the two seal area.
3 pressure drop large: medium inlet, outlet pressure drop more than design requirements, and even higher than the design value of many times, seriously affect the system of flow and temperature requirements. In the heating system, if the heat side pressure drop is too large, then a side flow will be seriously inadequate, that is, the heat source is not enough, resulting in the two side out of the temperature can not meet the requirements.
4 heating temperature can not meet the requirements: the main feature is the export temperature is low, can not meet the design requirements
