Product Description

RUNLAN XF Series automatic self cleaning water filters 
 
Brief Introduction  
XF Series self-cleaning strainer has metal filter cartridges inside. When filter elements clogged, a specially designed back-flushing arm will clean the elements one by one. When filtering, the water enters the element from both ends. When self-cleaning, the top end partly opens and the water flushed out of the bottom end.
XF Series self-cleaning strainer has very large filter area, high flowrate, compact structure and high reliability and works better for high flowrate and dirty water filtration applications. XF self-cleaning strainer has tow sub-series: M Series, for the low flowrate or filtration at rating > 300 μm. S Series, for the filtration at rating < 300 μm. Single filter flowrate range is 5~3000 m3/h. The inlet and outlet nozzle range is 2"~24".  
  XF Series self-cleaning strainer is capable to remove the solid particles from water and low viscosity liquid (metal working coolant for example). XF Filter makes the fluid meet the cleanness requirement and protects the downstream key equipment from clogging, abrasing and fouling. It increases the key equipment running efficiency and service life. XF s eries  self-cleaning strainer automatically works continuously on-line; it reduces the downtime cost, maintenance cost and labor cost.   XF Series self-cleaning strainer is an ideal solution for water and low viscous liquid self-cleaning filtration.
 
Filter Structure and Main Parts  
 
Working Principle
 
 [ Filtering ] Liquid flows into the filter via the inlet, part of liquid flows directly through filter elements from the lower ends; another part of liquid flows through the distribution pipe and into the upper part of the filter and then flows into the filter elements from the upper and lower ends at the same time,and then flows through the internal surface of filter element and goes out from the outlet. Impurities are intercepted by the elements and the filter cake slowly accumulates, which leads to gradually pressure drop increasing between the inlet and outlet. It indicates that the filter cake reaches certain thickness,and the flux of filter element becomes lower  

[ Back-flushing ] When the preset pressure drop or time exceeds, the self-cleaning program is triggered. The gear motor drives the cleaning arm to aim at one element to partly cap the upper end of the element and connect its lower end to the cleaning nozzle. And then the cleaning valve opens and connect the element and discharging pipe. the differential pressure between the element's outside and discharging nozzle will make the filtrate back-flush the filter element, filter cake dislodged and be purged downward into the sewage pipe. After one element cleaned, the cleaning valve closes and the cleaning arm aims at the next one. When all filter elements cleaned, the entire back-flushing sequences are completed.


[ Positioning ] Positioning disc and cleaning arm are installed on the shaft driven by the gear motor. Each positioning hole on the disc matches each element and cleaning arm are corresponding to one hole. When one hole reaches the channel of positioning sensor, the sensor output the signal to stop the gear motor. The cleaning arm has aimed at one element at the same time. The cleaning valve opens for several seconds till the element is cleaned. Then the gear motor continues rotating. When the next hole on disc reaches the sensor channel, the gear motor will stop and the next element is cleaned .
