Vandkvaliteten i industrielle cirkulerende vandsystemer kan ændres på grund af en række faktorer . For eksempel i nogle kemiske produktionsprocesser kan materialelækage forårsage en betydelig stigning i det organiske indhold i vandet; I cirkulerende vandsystemer, der opererer under miljøer med høj temperatur, kan opløste salte i vandet stige i koncentration på grund af fordampning og koncentration; Derudover vil vækst og reproduktion af mikroorganismer også påvirke vandkvaliteten, hvilket forårsager en stigning i urenheder såsom suspenderet stof og kolloider i vandet .
Self-cleaning filters usually trigger cleaning based on pressure difference and time. Pressure difference control is based on the pressure difference between the inlet and outlet of the filter. When impurities in the water gradually accumulate on the surface of the filter, causing the inlet and outlet pressure difference to reach the set threshold, the system starts the cleaning procedure. Time control is to clean at a preset Fast tidsinterval . i lyset af skiftende vandkvalitet og kun at stole på disse to konventionelle metoder opfylder ikke altid behovene .
When the water quality deteriorates and impurities increase, if it is still operated according to the original longer cleaning cycle, the filter will quickly clog, resulting in a sharp increase in water flow resistance and a decrease in circulating water flow, affecting the cooling effect of production equipment. At this time, the cleaning cycle should be shortened. Online water quality monitoring equipment can be used to monitor key indicators in the water in real time, Såsom turbiditet og indhold af suspenderet stof . Når det konstateres, at disse indikatorer overstiger det normale interval, hvilket indikerer, at vandkvaliteten er forværret, skal rengøringsintervallet blive forkortet i overensstemmelse hermed . for eksempel, hvis vandkvaliteten åbenbart forværres, kan rengøringstidens interval justeres til hver 4 time, hvis vandkvaliteten renses hver 8 time {.}}}}}}}}}}}}}}}}
On the contrary, if the water quality is good and there are fewer impurities, a long cleaning cycle will cause unnecessary energy waste and equipment loss. Because each cleaning requires a certain amount of energy to drive the cleaning device, frequent cleaning may also cause wear on the filter. At this time, the cleaning cycle can be appropriately extended. For example, after a period of monitoring, it is found that the Vandkvaliteten er stabil, og urenhedsindholdet er lavt, og rengøringscyklussen kan udvides fra de originale 6 timer til 10 timer .
Ud over at justere rengøringscyklussen i henhold til vandkvalitetsindikatorer, er det også nødvendigt at kombinere driftsbetingelserne i systemet . Hvis den industrielle produktionsbelastning øges, vil strømningshastigheden og strømningshastighed Cyklus kan muligvis forkortes; Når strømningshastigheden falder, kan rengøringscyklussen udvides korrekt .
In addition, different types of self-cleaning filters have different cleaning effects and adaptability to water quality changes. In the selection stage, the possible water quality fluctuation range of the industrial circulating water system should be fully considered, and filters with good cleaning effect and high adjustment flexibility should be selected. For example, some self-cleaning filters with intelligent control systems can automatically optimize the cleaning cycle according to various Vandkvalitetsparametre og driftsdata for bedre at tilpasse sig vandkvalitetsændringer .
