Precautions for replacement of gaskets of plate heat exchanger_
After long-term use, the gasket of the 781 plate heat exchanger will inevitably lead to failure, aging, wear, etc. At this time, in order not to affect the normal use of the plate heat exchanger, we must replace the gasket of the plate heat exchanger in time , Then what issues should be paid attention to when replacing the gasket of the plate heat exchanger? The following editor will tell everyone about the precautions for replacing the gasket of the plate heat exchanger. It is not a simple and easy task to replace the gasket of the plate heat exchanger. If the operation method is not appropriate, problems such as leakage and liquid leakage of the plate heat exchanger will easily occur. What should be done? Each heat exchanger plate is coated with a fluorescent test agent. Check for small cracks and corrosion holes under the irradiation of ultraviolet light. And clean it again. In addition. Also focus on checking the condition of the seal groove. Trim if necessary. Check the bonding position and bonding quality of each plate heat sink. Classified according to the order of installation. Then carefully assemble the plate heat sink group. After the plate heat exchanger is chemically cleaned. Use a high-pressure blowing device to remove the chemical medium remaining on the surface of the plate heat exchanger. Reuse performance inspection and testing. When rust is suspected, check the wall thickness of the heat exchanger and pipes. Remove the aging seals on the plate heat exchanger. According to different dirt, use acid-alkali cleaning tank for chemical cleaning. The surface of the cleaned parts will not be corroded by chemical media. The above are some of the issues that need special attention when replacing the gasket of the plate heat exchanger. I hope it will be helpful to you.
