Product Brief Description
Thesuction backwash filteris an industrial automatic filter that provides a variety of
comprehensive applications, especially for ships and offshore
platforms. The suction backwash filter can have a different number
of filter elements in each filter to provide a larger filter area.
This allows the filter to be used with minimal pressure loss. The
filter provides automatic, backflush cleaning operations and can
continuously separate impurities from water and other liquids. The
suction backwash filter is easy to maintain and operate and
maintains good operating conditions even under harsh operating
conditions.
Product Details (Core Parts)
Product Features:
The design of the pressure in the main part of the filter is
usually based on the standard design of chemical pipe filters and
steel pressure vessels. Filters can also meet the special
requirements of other design standards. The main body of the
equipment is made of carbon steel, stainless steel, duplex steel
and other materials. We can also provide you with titanium, pure
nickel and other special materials.

Product working principle
The sewage to be filtered enters the shell from the lower part of
the filter, enters the inner cavity of the filter element from the
bottom to the top, and then flows out through the filter element.
After filtering, the purified water flows out through the outlet at
the upper part of the filter, and the solid impurities are trapped
inside the filter element. When the filter element is backflushed,
it is not necessary to cut off the water inflow. The motor drives
the filter element suction cup to rotate while opening the
backflush blowdown valve. Each filter element is backwashed with
filtered water.
As a result of the differential pressure between the water pressure
and atmospheric pressure in the filter, the filtrate flows
backwards to remove the impurities trapped on the inner wall of the
filter element. After one revolution of the suction cup, the recoil
ends. The recoil valve closes and the drive motor stops.
Product Advantage
Thesuction backwash filteradopts multi-layer mesh filter element structure, which can
maximize the effective filtering area; the high-efficiency backwash
technology, combined with the laser welding technology, the filter
is especially suitable for the sea and ships.
In addition to satisfying the flow rate of normal design, a set of
the sparefilter elementsis added. When cleaning is required, the spare filter element is
started, so it will not affect the pipe resistance. The cleaning
assembly is in the form of sucking up and down, which maximizes the
cleaning of impurities in the shortest time.
Clean the gasket at the rotating shaft and filter element
faceplate, and have automatic adjustment function according to the
wear, so as to minimize the side leakage.
