Sucking type multi-component back flush filter

• U-ZC-XD1/XD2 automatic sucking type multi-filter elements back flush filter is suitable for the impurities filtration of high flow, high speed, low viscosity fluid.

  Automatic backwash filters are electromechanical integrated products with advantages of reasonable design, high filtering efficiency, low operation cost, continuous filtration even during the backwash process,etc. They are widely used in metallurgy petrochemistry, electricity, oil field water injection, ship ballast water, sea water utilization, environmental protection water treatment and many other fields.

   

  

  Automatic sucking type back flush filter characteristics：

   

  1. The filtering device adopts the patent technology of internal mechanical structure, to realize the function of backwash in the true sense, can thoroughly remove strainer intercept the impurities, no deed corner in cleaning, buy without attenuation, guarantee the filtration efficiency and long service life;

  2. The filtering equipment selection, 304, 316 l, 2205, MONEL, etc;Wedge filter material, strength, high accuracy, corrosion resistance, high filtration affection degrees can be up to 25 microns;

  3. The filtering equipment through its retrieval and strain function, automatic backwash, can deal with unstable water quality fluctuation, without human intervention;

  4. Responsive filtering equipment control system, operating precision, can be adjusted according to different water sources and filtration precision backwash differential pressure and time value;

  5. Filtration equipment in the process of backwash, groups of filter backwash operations in turn;To ensure safe and efficient filter cleaning, while the other mesh is not affected and continue to filter;

  6. Filtration equipment adopts pneumatic drain valve, backwash lasted short, backwashing water in the water consumption, less environmental economy;

  7. Filtration equipment design compact and reasonable structure, cover an area of an area small, easy installation and flexible mobile;

  8. Filtration equipment wearing parts for equipment is less, no consumables, low operation maintenance cost, simple operation management;

  9. Filtration equipment working condition set by touch screen display, differential pressure and time convenient and intuitive.

   
  working principle:
   

  The fluid containing impurities enters the bottom chamber (1) of the full-automatic filter, where the flow velocity of the fluid in the pipeline is reduced, and the fluid continues to flow upward. From the inside to the outside, it passes through the filter element assembly (2) specially arranged and sealed in the filter chamber, and the impurities are intercepted in the filter
  
  On the inner surface of the core, the filtered clean fluid flows out to the outlet (3).
  
  Backwashing is accomplished by using the differential pressure between the line pressure and atmospheric pressure. When the differential pressure transmitter (6) detects that the differential pressure value reaches the set value, the backwash suction device (4) is driven and rotated by the motor (5), and the blowdown port (6) is opened, at this time, the blowdown port is connected with the atmosphere to form a differential pressure, and the clean fluid outside the filter element carries out backwash on the filter element assembly. The backwash suction device will select the filter element group according to the characteristics of impurities
  
  The residence time of the filter elements and backwash each group of filter elements in the filter chamber one by one.
  
  When the pressure difference returns to the initial value, the blowdown valve closes, the motor stops driving, the filter continues to filter, the whole process flows continuously, and the backwash water volume is small, which does not affect the outlet pressure. The control system (7) can be remotely controlled by DCs, and the backwash time can be adjusted.

  Economic flow (150 μ m): for reference only, the flow is affected by liquid viscosity, filtration accuracy and cleanliness, please confirm with the engineer of younet
  Maximum working temperature: it can only be achieved with high temperature resistant sealing ring and sealing mechanism
  Maximum working pressure: This is the standard working pressure. If you need higher working pressure, you can customize it.
  Recommended cleaning pressure difference: 0.06mpa, for reference only, depending on the liquid and particle shape
