Regardless of the type of mechanical fine screens, the operator should regularly inspect it. According to the change of the water level before and after the fine screens or the amount of fine screens slag, turn on the slag remover in time to remove the fine screens slag. At the same time, pay attention to observe the operation of the slag remover and eliminate all kinds of faults in time. Check and adjust the flow control valve in front of the fine screens to ensure the uniform distribution of the flow across the fine screens. At the same time, the number of fine screenss used for work is used to control the fine screens flow rate within the required range. When it is found that the flow rate across the fine screens is too high, appropriately increase the number of fine screenss for work. When the flow rate of the fine screens is found to be too low, appropriately reduce the number of fine screenss for work. With the extension of the running time, sand may accumulate in the channels before and after the fine screens, and the sand accumulation should be checked and cleaned regularly, and the cause of the sand accumulation should be analyzed.www.khnwatertreatment.com
