Plate heat exchanger is a kind of heat exchange device with compact structure and easy to assemble and disassemble, so it is more convenient for cleaning and maintenance. The plate heat exchanger is composed of a variety of components. Today, I will talk about several important parts in the plate heat exchanger and how they play a role in the heat exchanger. I believe that after understanding these, I can help you Provide some help in maintenance work

1.front pillar supports the weight of the heat exchanger, so that the entire plate heat exchanger is integrated.

2.movable pressing plate is used in conjunction with a fixed pressure plate, which can be slid on the upper guide rod for disassembly, inspection and maintenance.

3. up and down guide rod bear the weight of the plates and ensure that the plates slide during installation. The guide rod is usually longer than the heat exchange plate group to loosen the compression bolts and slide the plates for inspection.

4.gasket Prevent fluid mixing or leakage, and distribute it among different plates. The materials are: nitrile rubber, EPDM, fluorine rubber, etc. Different rubbers are used according to different media.

5.heat exchange plate Provide medium flow channel and heat exchange area. Generally, the corrugation is made into a herringbone shape. According to the different fluid medium, the material of the heat exchange plates of the plate heat exchanger is different, and most of them are made of stainless steel and titanium.

6.fixed pressure plate do not contact with fluid, tighten the gasket with clamping bolts to ensure sealing.

7.compression bolts and nuts The plate pack is compressed to integrate the heat exchanger and ensure sealing.

The description of the important components and functions of the plate heat exchanger is here. Any of the above components plays a vital role in the heat exchanger. In the process of maintaining and overhauling the heat exchanger, if any part of it is found to be damaged, it should be replaced in time, otherwise it will seriously affect the normal use of the heat exchanger.
