    ZLSH type full automatic back flushing water filter is the product that we introduce and absorb foreign advanced technology. The filter has continuous filtration, automatic flushing sewage, compact structure. The operation process is reliable, the processing capacity is big, the sewage water consumption is small, and the operation cost is low. The cleaning and discharging process of the ZLSH type full automatic back flushing water filter is automatically operated in the process of equipment operation. ZLSH type water filter mainly used in power plant auxiliary cooling water, industrial circulating water, fire water, sewage, water, washing liquid and similar suspension coarse filter and fine filter.

    ZLSH type automatic backwash water filter is divided into low-precision filtration (1-6mm) and high-precision filtration (10-500μm). The filter element of low-precision water filter is made of stainless steel trapezoidal strip by special process, so as to form variable clearance filter hole, which is easy to wash; The filter element of high-precision water filter adopts special stainless steel twill mesh (or stainless steel fiber sintered felt), and the inside and outside are made of stainless steel square hole framework by special welding process, which not only ensures strict filtering accuracy, but also ensures that the filter screen has sufficient strength.

    ZLSH automatic backwash water filter can be divided into two kinds of connection modes: upper inlet and lower outlet and lower inlet and upper outlet.

■General technical parameters:

  ● Nominal design pressure: 0.6MPa, 1.0MPa, 1.6Mpa              

  ● working pressure: ≤ 1.0MPa, ≤ 1.6Mpa

  ● Water supply pressure (inlet water pressure) ≤ 0.25MPa     

  ● Back pressure at outlet of water filter: ≥ 0.15Mpa  

  ● filtration pressure loss: 0.02 ～ 0.1MPa                       

  ● filtration accuracy: (10-500μm), (1-6mm) (optional by customers when ordering)

■standard equipment configuration:

  The main body of the water filter, electric control box (generally installed separately or integrated with the water filter), electric drain valve, anchor bolt, inlet and outlet counter flange, differential pressure controller.

TECHNICAL DATA

  The above table flow parameters are derived from the 3m/s.

■Installation Requirements

    ①Order to facilitate the maintenance and repair of the filter or the system water supply, the inlet and outlet of the filter should be provided with the bypass line and valve. In order to ensure the filter of 

    ②The filter press head, the outlet of the filter should be provided with a manual valve,Which can adjust the pressure of the water outlet chamber, so that it can produce a certain counter flushing back pressure head.
