Plate heat exchanger 11 large parts of the function

Plate heat exchanger 11 large parts of the function:

1, fixed compression plate: not in contact with the fluid, with clamping bolts tighten the pad to ensure sealing.
2, heat transfer gasket: to provide media flow and heat transfer surface.
3, gasket: to prevent the fluid synthesis or leakage, and to the distribution between the different plates.
4, take over, flange: to provide import and export of fluid.
5, the upper and lower guide: to withstand the weight of the plate and to ensure that the installation size, so that the slide between the slide, the guide rod is usually longer than the heat exchanger board, in order to release the clamping bolt sliding plate inspection cleaning.
6, rolling device: the activities of the compression plate or the middle partition can slide on the upper and lower guide bar for inspection and maintenance.
7, the activities of the pressure plate: paired with a fixed compression plate can be used to slide on the guide bar, in order to disassemble inspection and maintenance.
8, the former pillars: support the weight of the heat exchanger, so that the entire heat exchanger into one.
9, clamping bolts: compression plate group, so that the overall heat exchanger to ensure that the seal, for rubber seals generally marked on the label and the maximum size of 10, the minimum compression size, when pressed to the minimum size Replace the gasket.
11, the middle partition: fixed compression plate and movable compression plate in the middle of the middle of the installation of the middle partition, can make a device at the same time dealing with a variety of media, the implementation of multi-stage operation.

Plate heat exchanger stainless steel heat transfer plate made of mechanical stamping, inevitably residual a certain amount of surface residual stress, for the molybdenum-free stainless steel sheet, the surface residual stress is very difficult to eliminate, or even not feasible of. Plate assembly after the formation of a multi-slot structure, such as the contact between the plates, sealing the bottom of the tank and other parts. And the gap is likely to cause the enrichment of Cl-, the local enrichment is often far more than the resistance of stainless steel itself, the ability of corrosion.
