The plate heat exchanger Plate heat exchanger is mainly composed of heat transfer plate, sealing gasket, pressure plate at both ends, clamping bolt, bracket and so on. The functions of various components of plate heat exchanger are as follows: a, heat transfer plate heat transfer plate is the primary heat exchanger for the role of components, usually corrugated made of herringbone, according to the fluid medium is not the same, the data of heat transfer plate is not the same, mostly made of stainless steel and titanium.
Features
Sealing gasket plate heat exchanger sealing gasket is mainly in the heat exchange plate between the sealing role. Data are: nitrile rubber, epDM rubber, fluorine rubber and so on, according to different media choose different rubber. Three, both ends of the pressure plate at both ends of the pressure plate is the first clamping pressure on all the heat transfer plate, to ensure that the fluid medium does not leak. Four, clamping bolt clamping bolt is the primary role of fastening both ends of the pressure plate. The clamping bolt is usually double-threaded, so that the torque of the fixing plate is uniform when the bolt is pretightened. Five, the hanger is mainly to support the heat exchange plate, so that it is easy to disassemble, clean, assemble and so on.
Current performance
It has become a highly competitive product in the heat exchanger field or evenly has replaced conventional tubular heat exchangers. With its development, it will be used in more and more fields.
Plate and gasket
The plate materials and the gasket materials mainly depend on the corrosive properties and temperatures of the cold exchange medium and the heat exchange medium.
The plate heat exchanger's plate materials and corresponding applicable places are given in Table 1 and its gasket materials and corresponding applicable places in Table 2 for your reference.
