XT self-cleaning filter
  • Product introduction
  • Product advantage
  • Model Selection
  • Typical cases

  x series of full auto self-cleaning filer is a kind of motor-driven suction filter. cleaning organism is driven by an electric motor. filter screens which has diameter between 20 micron-500 micron can be equipped depends on various situations, caliber ranges from 8”to 24”. x series filters have three structural styles: vertical type, horizontal type, online type.

filtering process:
filthy water enters from filter inlet, and then it gets through fine-mesh filter screen from inside to outside. during the process of which impurities larger than screen mesh are blocked and accumulated on the internal surface of filter screen, gradually filter cake come into being. and meanwhile these filter cakes can catch smaller impurities in water.
sewage are exhausted by drain outlet in process of drainage, pressure difference switch can detect pressure difference between inside and outside of filter continuously, when default value is reached, a switching signal shall be transferred into controlbox to start up one cleaning recycle.

self-cleaning process
cleaning mechanism of filter is made of stainless steel 316l material and is a suction&scanning machine which rotates and moves up and down. it has a hollow-core construction. several suction nozzles are uniformly distributed on suction machine, internal part of suction&scanning machine communicates with a 3”drainage valve. when drainage valve is open, differential pressure produced between internal water pressure of filter and outside atmosphere provides strong suction power to every suction nozzle. at every suction nozzle, water flow from outside of filter to inside of it in high speed, thus impurities shall be flushed down into scanner and exhaused by drainage valve, reverseflow in high speed at suction nozzle is strong enough to absorb stubborn impurities on filter screen. suction&scanning machine is driven by a two-way electric motor connected with leadscrew, and makes spiral motion in unchanged rpm, which several suction nozzles can suck all over the internal surface of filter in process of 35-60 seconds. during all backflush process, system has continuous flow.

control system
it is auto-controlled by industrial single-chip plc, displayed in chinese. it can timingly control backflush according to pressure difference, and clean manually or compulsorily, even in condition of power failure. filter interval time, cleaning time, operating time, operating signal, cleaning signal, fault signal output and communication signal output can be set on site.

range of application
1、cooling water treatment---cooling tower, make-up water system, air-condition system, dc system water filter, reduce sediment produced in heat-exchanger so as to keep cooling effect.
2、raw-water treatment---filter surface-water, lake-water, sea-water, water in reservoir, well water and ground water so as to remove sand, germ, algae, organism and so on.
3、filter industrial recycling water---some equipments has certain requirements in respect of water quality, such as: cooling tower, rolling mill, continuous casting machine, buffing machine, water pump, solenoid valve, ion-exchange, sprayer, heat exchanger or water-supply line or drain line. impurities in water can be removed to avoid blockage in pipeline, nozzle and other parts.
4、irrigation---especially used for water resource in high flow capacity and high impurities content , such as: agriculture irrigation, spray irrigation, park, golfcourse, turf potting and so on.
5、paper industry--- off -machine water filtration
6、plastic industry---product recovery cooling water filtration
