The plate heat exchanger is a high-efficiency heat exchanger which is assembled from a series of metal sheets with a certain corrugated shape. A thin rectangular channel is formed between the various sheets, and heat is exchanged through the sheets. Plate heat exchangers are ideal for heat exchange between liquid-liquid and liquid-vapor. The maintenance of the plate heat exchanger is as follows:
(1) After long-term operation of the plate heat exchanger, the surface of the plate will produce different scales or deposits, which will reduce heat transfer efficiency and increase flow resistance. Therefore, the equipment should be periodically disassembled and inspected for dirt removal according to the actual conditions such as water quality and temperature medium characteristics.
(2) Damaged plates should be replaced in time. If there is no spare plate, two adjacent plates can be removed if the operation permits (the two plates should not be the reversing plate but the plate with four holes), and the clamping size should be reduced accordingly.
(3) When assembling the plate heat exchanger, the plates and gaskets should be kept clean and placed neatly, and the plates should be assembled according to the product assembly form.When tightening, the stud should be pressed tightly and the force should be uniform
