Plate heat exchanger is a kind of heat exchanger equipment with high operating efficiency, which is made by stacking corrugated metal sheets. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, wide application, and long service life. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, and the floor area is one-third that of the tube heat exchanger, and the heat recovery rate can be as high as more than 90%. It is also a technical work to replace the rubber parts of the plate heat exchanger. Next, we will take a look at the steps of replacing the rubber parts of the plate heat exchanger. I hope it can be helpful to you.
1. The plate heat exchanger is subjected to chemical cleaning. We can use a high-pressure blowing device to completely remove the chemical media remaining on the surface of the plate heat exchanger and other surfaces;
2. Check the bonding position and bonding quality of each plate heat sink. Sort by installation order. Then carefully assemble the plate heat sink group;
3. Each heat exchanger plate is coated with a fluorescent test agent. Check for small cracks and corroded holes under UV light. In addition to re-cleaning, the condition of the seal groove must be checked. If it is found that it needs to be modified, it can be adjusted appropriately 4. Inspection and detection of reuse performance. Check the wall thickness of heat exchangers and pipes when rust is suspected;
5. Remove the aging seals on the plate heat exchanger. According to different dirt. Chemical cleaning with acid-base cleaning tank. The surface of the parts to be cleaned will not be corroded by the chemical medium.
The above is the introduction of the replacement procedure of the rubber parts of the plate heat exchanger. This step needs to be handled by professional operators. If everyone is not proficient in the operation, it is recommended to find a professional person to replace it. This is also to ensure that the plate heat exchanger equipment can function normally Prerequisites for use.
