Introduction to the maintenance method of spiral plate heat exchanger

Spiral plate heat exchanger is one of the most widely used equipment in industrial equipment. As the main equipment in the process of preheating, waste heat recovery, refrigeration, etc., it has made outstanding contributions to energy saving. Spiral plate heat exchanger is widely used in industry , Civil, and other fields, due to improper maintenance of the heat exchanger during use, it will affect the service life and production efficiency of the equipment. Then the daily maintenance and maintenance of the heat exchanger is more important. Which aspects should be maintained?

1. Regularly check whether the cleaning of each heat transfer sheet is complete, whether there are deposits, coking, scales, etc., and clean it immediately. At the same time, it is necessary to check whether the adhesion of each heat transfer sheet and the rubber gasket is tight. , Whether the rubber gasket itself is intact, so as to avoid leakage caused by degumming and damage of the rubber gasket.
2. The compression nut and upper and lower guide rods of the plate heat exchanger should be lubricated with lubricating grease frequently.
3. Special personnel should be responsible for the adjustment of each instrument, and strictly implement the operating procedures for operation and maintenance.
4. Every time the heat transfer sheet is re-compressed, pay attention to the position of the scale during the last compression. Do not over-press the rubber gasket, which may reduce the service life of the gasket.
5. Warm reminder, when replacing the heat transfer sheet rubber gasket, all the sections must be updated to avoid uneven gaps between the sheets, which will affect the heat transfer effect.
