Maintenance method of plate heat exchanger

The utility model has the advantages of small size, light weight, convenient maintenance, no need for maintenance and lifting facilities, and therefore less installation area. The manual maintenance of plate heat exchanger includes folding the whole machine, cleaning the plate and gasket with water spray gun and brush, checking the plate and gasket, replacing the plate and gasket if necessary.
                              
        Plate heat exchanger under normal circumstances to clean 1 times a year, and whether it is necessary to do so, so that the heat exchanger can maintain the efficiency of heat exchanger. When water quality is poor, such as river water, sea water, and the rapid growth of microorganisms, there is a risk of surface contamination and blockage due to the presence of sediment and dirt. In foreign countries, the use of river water as cooling water, the cleaning frequency is very high, with an average of 3.3 times a year. So the heat exchanger in the use of water should try to choose a more clean water, so that both can prevent the heat exchanger damage, but also can reduce unnecessary cleaning, to achieve cost saving effect.
