What matters can not be ignored in the process of maintenance of plate heat exchanger?

Analysis of common problems in the process of maintenance of plate heat exchanger, compared with ordinary plate heat exchanger, for the maintenance of brand plate heat exchanger or to pay attention to some problems, so as to avoid the failure of maintenance, affecting the normal use of heat exchanger. Maintenance personnel in the plate heat exchanger maintenance, do not ignore the following points of special attention.

Because the plate heat exchanger is easy to disassemble and install, the maintenance is simple, and the special tools and equipment are generally not used. According to different conditions, different methods can be used. If there is no leakage of the equipment, but the heat transfer system K is decreased, the heat exchanger can be dismantled, and the descaling liquid can be driven into the equipment with a closed circuit system for several hours. There is no such condition on the site, and when scaling is not too serious after disassembly of the equipment, the plate can be removed and directly washed with water, and the soft brush can be used at the same time.

For the normal operation and maintenance of plate heat exchanger, the equipment to be repaired should be disassembled retrograde according to the installation sequence. The equipment used in petroleum and chemical industry should be maintained regularly according to the maintenance cycle. If the medium in the equipment is inflammable, explosive, or corrosive, it should be repaired at least once a year. Plate heat exchanger used in other industries, if there is no leakage, check and repair once every three years.
