What are the leaking parts of the plate heat exchanger
The main part of the plate heat exchanger is the seal between the plates, the two sealed and sealed groove portions, and the inside of the end plate and the compression plate. The pressure drop is large: the medium pressure drop at the inlet and the outlet exceeds the planned requirements, and even many times higher than the planned value, which seriously affects the flow and temperature requirements of the system.
In the heating system, if the pressure drop on the hot side is too large, the primary flow rate will be seriously insufficient, that is, the heat source will not work, and the secondary outlet temperature will not meet the requirements. Straight liquid: The first feature is that the medium on the high pressure side is connected to the medium on the low pressure side, and the pressure and temperature in the system are abnormal. If the medium is corrosive, it may also cause corrosion of other equipment in the pipeline. Threading fluid usually occurs in the turning zone or possibly in two sealed zones. The heating temperature cannot meet the requirements: The first characteristic is that the outlet temperature is too low to meet the planned requirements.
The plate heat exchanger can change the heat exchange area and process combination according to the site requirements. Plate heat exchangers are widely used in metallurgy, petroleum, chemical, power, chemical fiber, medicine, food, papermaking and heating. Can be used for heating, cooling, transpiration, condensation and other conditions. It mainly consists of imported heat conducting fins, sealing rubber pads, clamping bolts and compression plate structures. Resistant to various corrosive media.
The heat transfer efficiency is high, and the cold and hot media pass through adjacent channels to perform heat exchange through each channel. Due to the herringbone wave on the plate, the movement of the medium will form turbulence, thereby achieving higher heat exchange efficiency. High efficiency and energy saving, high heat transfer coefficient. The heat transfer coefficient can reach 3000-4500kcal / m2.? Ch at the same flow rate, it is more than 3 times that of the shell and tube heat exchanger.
