Plate heat exchanger has been widely used in metallurgy, mining, petroleum, chemical industry, electric power, medicine, food, chemical fiber, paper making, textile, shipbuilding, etc. It can be used for heating, cooling, evaporation, condensation, sterilization, waste heat recovery and other conditions. Solar energy utilization: It is involved in the heat transfer process of antifreeze such as ethylene glycol in the heat transfer medium of solar collector panel, so as to achieve the use of solar energy. Purpose.

Seawater aquaculture and nursery: supporting boiler to raise the temperature of nursery seawater saves the use of coal, thus saving energy and improving environmental protection. Efficiency. Other: pharmaceutical, petroleum, ceramics, glass, cement, geothermal utilization, etc. Plate heat exchanger plate heat exchanger leaks are mainly manifested as leaks (small, discontinuous droplets) and leaks (large, continuous droplets).

*The main parts of the leaks are the seals between the plates, the leak slots in the second seal of the plates, and the interior of the end plates and pressure plates. The main characteristic of liquid crosstalk is that the media on the higher pressure side crosstalks into the media on the lower pressure side, and abnormal pressures can occur in the system and temperature. If the medium is corrosive, it may also cause corrosion of the plate heat exchanger gasket. Crosstalk usually occurs in the manifold or secondary seal area.

*Media with large pressure drops have inlet and outlet pressure drops that exceed the design requirements and are many times higher than the design values, significantly affecting system flow and temperature. requirements. In heating systems, if the pressure drop on the hot side is too great, the primary side flow will be severely inadequate, i.e., the heat source will not be sufficient, resulting in a secondary side temperature that cannot be Meet requirements. The main feature is that the outlet temperature is too low to meet the design requirements.
