Because the plate heat exchanger works for a long time, the surface of the heat transfer plate will produce different degrees of dirt or deposits, thereby increasing the flow resistance and reducing the heat transfer performance. These are mainly the pressure difference between the inlet and outlet pressure gauges and the temperature of the cold medium outlet. Reduced, so we have to clean it, we need to debug the experiment after the cleaning is completed to ensure the normal use of the product, then what are the things we need to pay attention to during the debugging process?

       1. A certain inspection site should be reserved around the location of the plate heat exchanger.

       2. Before installation, the pipeline connected to it should be cleaned to prevent sand, oil, welding slag and other debris from entering the plate heat exchanger, causing obstruction of the flow channel or damage to the plate. The plate heat exchanger has a small footprint and light weight. Except for the volume of the device itself, no additional inspection and installation space is required, and the thickness of the plate used for heat exchange is 0.6-0.8 mm.

       3. Opening and stopping sequence of plate heat exchanger

       When shutting down, first close the high-pressure side medium solenoid valve, and then close the low-pressure side medium solenoid valve. In today's exaggeration of high efficiency, environmental protection and energy saving, the advantages of plate heat exchangers in the field of heat exchange have become increasingly prominent, and can be used in heating, cooling and food disinfection in various processes, in terms of low-grade heat energy recovery. It also has significant economic benefits.

       When starting up, first open the low-pressure side medium plunger valve, and then open the high-pressure side medium plunger valve slowly after the medium fills the plate heat exchanger channel.

       4. Check if the clamping bolts are loose before putting into use. If necessary, tighten them. In recent years, plate heat exchangers have replaced traditional shell-and-tube heat exchangers in airports, hotels, commercial buildings, etc., and have achieved good results.

       maintenance:

       5. If there are often large particles of muddy sand or debris in the medium, the supporting decontamination equipment produced by our factory should be arranged in front of the plate heat exchanger. The plate heat exchanger has a low fouling coefficient, and the fluid violently rolls between the plates to form a turbulent flow. The plate design avoids the existence of a dead zone, so that impurities are not easily deposited and blocked in the channel, and a good heat exchange effect is ensured.

       The above is the various things we need to pay attention to during the debugging process after cleaning. When we understand these matters, we can guarantee the better use of the product.
