Precautions during installation of plate heat exchanger
During the installation process of plate heat exchanger, in order to ensure the installation quality, there are usually many different matters that need our attention to ensure the installation efficiency and operation of the equipment, so for the convenience of everyone to understand, the following is related The matters will be introduced.
1. Pay attention to the weight and focus of the equipment when hoisting.
2. When bonding the heat exchanger gasket to the heat exchanger plate, make sure that there is no sand, oil, iron filings, welding and other sundries on the heat exchanger gasket and in the gasket groove of the heat exchanger plate. So as not to damage the heat exchanger seal and cause leakage.
3. When tightening the bolts, the force should be even, and the distance between the inner sides of the two compression plates should be continuously measured to ensure that the parallelism deviation between the two clamping plates is not more than 1mm, so as to prevent the gasket from being biased or slipping out of the gasket groove. At the same time,-while clamping-while carefully inspecting, observe whether there is any misalignment of gaskets and plates.
4. Water is generally used as the liquid for hydraulic experiments. The water temperature should not be lower than 5 degrees Celsius. The pressure should be increased slowly during the experiment. After the test is completed, properly loosen the compression nut to release the water in the heat exchanger. Then tighten the nut, clamp to the original size, and set aside.
5. There should be a certain maintenance space around the plate heat exchanger, and the size should be determined according to the size of the heat exchanger plate.
6. Apply butter on the clamping bolts and put on a protective tube to avoid rust and damage to the threads.
7. If the higher pressure at the outlet of the pump is greater than the higher operating pressure of the equipment, a pressure reducing valve and safety valve should be installed at the entrance of the equipment.
8. When the equipment is filled with liquid and under pressure, it is not allowed to tighten the nut.
The matters that need our attention during the installation of the plate heat exchanger mainly include the above eight points. Learn more about the requirements of each related item, so as to rationally install the equipment and effectively improve the efficiency of the equipment.
