The X-series fully automatic self-cleaning filter is an electric sucking filter that is driven by an electric motor to clean the filter. For different applications, it can be equipped with a 20-500 micron filter screen with a diameter of 2 "- 24". The X series filter has three structural types: XT vertical and XM horizontal.

Model description
Example X T M G D-200/10
X represents suction cleaning, T represents vertical installation, and M represents vertical installation, G represents the high-pressure auxiliary flushing pump, D represents high flow rate,  200 inlet and outlet diameter, 10 represents the nominal pressure.

Filtration process
Dirty water enters the filter inlet and then passes through the fine filter screen from inside to outside. At this time, impurities thicker than the mesh are intercepted and accumulated on the inner surface of the filter screen to form filter cakes, which can also catch some finer impurities in the water.
During sewage discharge, the sewage is discharged through the drain outlet, and the differential pressure switch continuously detects the pressure difference inside and outside the filter screen. When the preset value is reached, a switch signal will be transmitted to the control box to start a cleaning cycle.

Self cleaning process
The cleaning mechanism of the filter is a stainless steel 304 material suction scanner that rotates and moves up and down. It is a hollow structure, with several suction ports evenly distributed on the suction scanner. The inside of the suction scanner is connected to a 3 "electric drain valve. When the electric drain valve is opened, the pressure difference between the internal water pressure of the filter and the external atmosphere creates a strong suction force at each suction port, The water flows out of the filter screen at a reverse high speed from the outside to the inside, flushing impurities down into the scanner and discharging them through the drain valve. The high-speed reverse water flow at the suction port is sufficient to suck away stubborn impurities on the filter screen. The suction scanner is driven by a bidirectional electric motor connected to a screw device and performs a spiral reciprocating motion at a fixed rotational speed, so that multiple suction nozzles can suck through the entire inner surface of the filter screen. This process takes approximately 30-120 seconds. During the entire backwash process, the system does not shut down.

control system
Adopt industrial single chip PLC for automatic control, in Chinese or English. The filter can be automatically cleaned according to pressure difference or timing control, and can be manually or forcibly cleaned. Filtration time and cleaning time can be set on site. Operation signal, cleaning signal, fault signal output, and 485 communication interface.

Scope of application
1. Cooling water treatment - water filtration for cooling towers, make-up water systems, air conditioning systems, and once-through systems to reduce the generation of sediment in heat exchangers and maintain their cooling effect.
2. Raw water treatment - It can filter surface river water, lake water, seawater, reservoir water, well water, and groundwater to remove sand, bacteria, algae, organic matter, and so on.
3. Filtration of industrial circulating water - it can be used on equipment with certain requirements for water quality, such as cooling tower, rolling mill, continuous caster, polishing, water pump, solenoid valve, ion exchanger, spray, heat exchanger, etc., or water supply and drainage pipelines to filter out impurities in water and avoid blockage of pipes, nozzles and other parts.
4. Irrigation - Especially suitable for water sources with high flow and high impurity content, agricultural irrigation, sprinkler irrigation, parks, golf courses, turf irrigation, etc.
5. Paper industry - white water filtration.
6. Plastics industry - injection molding cooling circulating water filtration. injection molding machine
7. Membrane pretreatment, resin pretreatment, ultrafiltration pretreatment.
8. Seawater desalination pre-treatment filtration, aquaculture filtration
