refrigeration heat exchangers

Textile industry: cooling of viscose sericine aqueous solution, cooling of boiling nitrocellulose, etc.　　2. Let’s take a look at what are there. Sample size and roughness. Today we will understand the shutdown work of the lower plate heat exchanger, let’s understand it together~　　 1. The reason~　

　1, sampling location. Before the plate heat exchanger shuts down, the pump must be stopped and the power supply cut off; 　　 2. ​​Machinery industry: Plate heat exchangers are used in various quenching liquid cooling, reducer lubricating oil cooling, etc. The processing size and roughness of plate heat exchangers that do not meet the standard requirements will also cause performance inconsistencies. If you are interested, please refrigeration heat exchangers follow the plate heat exchanger manufacturers to take a look~　　1. Metallurgical industry: heating or cooling of aluminate mother liquor, cooling of steelmaking process, etc.　　 5. To ensure the service life of the plate heat exchanger, it is not only the correct use of the equipment, but also an important task, that is, the correct shutdown.Everyone knows a lot about the relevant knowledge of plate heat exchangers.　　

3. Plate type When the heat exchanger stops, first slowly close the heating medium inlet valve, and then close the cold medium inlet valve. The incorrect formulation of the heat treatment process will directly affect the structure and performance of the forging. Sampling at different positions along the wall thickness of the cylinder will have different performance. Power industry: high-voltage transformer oil cooling, generator bearing oil cooling, etc.　　 2. Heat treatment process. Finally, close the outlet valves of the two media; 　　 Fourth, for the higher temperature media and corrosive media, the plate heat exchanger should be stopped and vented as much as possible to avoid burns and corrosion of the equipment when the equipment is opened..

　　4.　　3. If you want to ensure the working quality of the plate heat exchanger, you need to ensure that the quality of each link is passed. If you don’t pay attention to it during production, it will cause the plate heat exchanger to have short sections. Close to the outer wall of the plate heat exchanger during heat treatment, the cooling rate is fast, and the tensile and impact properties are higher. Today we will explain some other applications of plate heat exchangers. If there is a vent valve on the pipeline, it should be opened; 　　 3.　　6. Food industry: fruit juice sterilization and cooling, animal and vegetable oil heating and cooling, etc. Paper industry: heat recovery in bleaching process, heating of washing liquid, etc
