refrigeration heat exchanger

The installation process of the refrigeration heat exchanger unit system: 1. Place the equipment on the foundation and fix the anchor bolts. 2. Check whether the inlet and outlet of the cold and heat medium of the pipeline are consistent with the connection on the equipment. Considering the convenience of maintenance, it is best to use short sections when connecting the pipe to the heat exchange unit. 3. Thermometers and pressure gauges should be installed at the inlet and outlet of the cold and heat medium of the heat exchange unit.

The assembly of the heat exchange plate of the heat exchanger: 1. The heat exchange plate of the heat exchanger is tilted back and sideways, and the guide rail is tightened around the support point of the guide rail. 2. After the heat exchange plate of the heat exchanger is put into the guide rod, center it as shown in the figure. 3. The heat exchange plates of the heat exchanger are assembled in strict accordance with the specified order, and the gaskets should not be loosened during assembly.

After the heat exchange plate of the heat exchanger is centered, manually move the cover plate to the fixed cover plate and slightly pre-press the cover plate. Tighten the four diagonal screws symmetrically. The middle screws follow in turn. Use a vernier caliper to measure the upper, lower, and left sides of the cover plate. , Right distance, keep the four screws basically the same distance. In the end, the gasket of each plate should have a compression deformation of about 20% to 25%. When necessary, hydraulic jacks can also be used to assemble and evenly press it manually to save time.

There should be a certain maintenance space around the heat exchanger, and its size is related to the size of the plate. 6. Grease the clamping bolts and put on a protective tube when possible to avoid rust and bruise the threads. 7. If the maximum pressure at the outlet of the pump is greater than the maximum operating pressure that is unwilling to bear, install a pressure reducing valve and a safety valve at the inlet of the equipment. 8. When the heat exchanger is filled with liquid and under pressure, clamping nuts is not allowed.
