    High-precision folding filter element can be widely used in petrochemical, oilfield pipeline filtration; Fuel filtration of refueling equipment and construction machinery equipment; Water treatment industry equipment filtration; Pharmaceutical and food processing sectors
    .

    Folding filter also chemical, medical, high temperature gas filtration, scientific research, metallurgy, food, machinery and other industries, is an important filter product
    of modern filtration technology center.

    Folding filter element cleaning and sterilization: 1: on the production line generally choose backwashing: first close the original solution and filtrate pipeline switch, rinse with bacteria-free water, input from the original outlet, discharge from the inlet or lower discharge hole of the filter, backwash to have pressure but not too large, generally about
    5 kg.

    2: Remove the filter element and put it in the cleaning liquid for cleaning, first soak in repeated cleaning
    .

    Cleaning liquid is generally available: A: sodium hydroxide, 0.
    1N NaOH B: 1-2% citric acid water flux or 0.
    1N oxalic acid solvent, 0.
    1N hydrochloric acid solvent: C: enzyme solvent and other solvents The general temperature is controlled at 30-40 degrees Celsius when cleaning Installation method: 1: When installing the plug-in filter element, the O-ring should be wet in the clean water cargo filtrate to reduce the friction during insertion
    .

    And it is required to be inserted to the end to ensure that the two O-rings are sealed
    .

    2: When installing the snap-in filter element, it is necessary to rotate and position
    it in a clockwise direction.

    3: If the filter has a pressure plate, the pressure plate is pressed on the warp, and the spring on the pressure plate is gently pressed, such as the spring overtightening filter element has no elongation space, which will produce distortion and deformation and affect the filtration accuracy
    .

    4: When filtering liquid, you should first open the exhaust switch on the shell, empty the gas in the filter cartridge, and fill the liquid with the filter cartridge, otherwise it will affect the flow rate
    .

    5: The fluid filter will produce pressure drop due to resistance, in order to overcome the resistance must have sufficient working pressure, in order not to make the filter element affected by large flow impact, open the valve slowly
    .
