    Schematic
    Working Process:
    When the backwash function of the heat exchanger unit is not turned on, the 4-way diverter valve is located in the ordinary water flow working position, electric 3-way valve closes the filter bypass, at this time the water flow of the secondary side of the plate heat exchanger is in the ordinary direction.When the backwash function of the heat exchanger unit is turned on, the 4-way diverter valve is located at the exchanged
    working position. The electric 3-way valve opens the filter bypass and closes the main road. At this time, the water flow of the plate heat exchanger is reversed, and the impurities in the heat exchanger are flushed by the reversed water flow to the filter bypass.After filtering, the impurities sink in the filter, and finally the impurities are removed by washing the filter.The cleaning function is implemented by a fully automatic control system, and the cleaning time can be based on the actual situation of the customer.The situation is adjusted, convenient and fast, and can achieve unattended and remote control.
  • Plate heat exchanger problem
    Plate heat exchanger problem:
    Plate heat exchanger unit is a widely used heat exchange device with compact size and high heat transfer efficiency.However, the impurities can easily block the passage of the plate,increase the resistance of the device during the working process,all this will result in reducing heat exchange capacity, affecting user comfort.The blockage in the heat exchange period is mainly due to the welding slag from the pipeline construction,the impurities brought in when the water replenishing to the pipeline system.The traditional cleaning method is to dismantle the sheets and clean up the debris after the working season.However, the problem cannot be disposed in time during the working season.
  • The traditional ways to Clean the Plate heat exchanger
    Traditional manual cleaning:
    The traditional method of replacing the cleaning plate is to remove the plate by manual removal, and remove the pieces of the plate, and wash it with a high-pressure water gun. Some of the scale deposits are too long and need to be completely removed by the syrup. The syrup is corrosive to the plate.
    The disadvantage of the traditional cleaning method is that it requires a lot of manpower and material resources to be wasted, and the damage to the board is also great.
