The thickness of the plate heat exchanger plate is substantially 0.4 mm to 0.8 mm. The thickness of the plate heat exchanger plate is mainly determined by the magnitude of the working pressure. The higher the working pressure requirement and the thicker phe plate thickness, the higher the production cost. On the contrary, the lower the user's needs, usually the plate is 0.5mm and 0.6mm thickness.
Most of the plates are designed to facilitate the fit of the gasket. Therefore, the smooth surface design is adopted at the joint between the plate and the gasket. The design of the smooth surface groove is often due to the user's lack of understanding of the plate heat exchanger, and the power is unbalanced during maintenance., And the plate is damaged and the entire plate heat exchanger is scrapped. Therefore, care must be taken when servicing plate-type heat exchangers with smooth surface grooves.
(1)The selection of the plates and gaskets for the initial purchase of the plate heat exchanger is correct
(2)Whether there is a device filter on the inlet of the two sides of the plate heat exchanger.
(3)Whether the water tower on the cooling water side is cleaned regularly ( only the water is discharged within a fixed time, use simple tools to clean the dirt in the water tower, do not use chemicals directly into the cleaning).
