Filter press special pump in the use of the key points

January 13, 2021

Filter pump special pump is designed to feed the filter press feeding or feeding pump, filter press is the core equipment supporting the filter press for the use of the pump directly related to the filter press The overall operation is normal. Press filter special key points in use when the point of attention Special filter press pump key points in use: The filter press pump at work, the flow and head constantly changing, so compared with conventional centrifugal pumps, The performance curve of a filter press pump has been changing, not always at a certain point. Work process is divided into three stages: 1, the beginning of the feed stage, due to no pressure in the filter press chamber, the medium quickly filled the cavity, the pump is running at high flow, low head, then consider the motor can not overcurrent, if Super-current conditions, to regulate the outlet valve, control flow; 2, the feed medium stage: With the filter press the liquid is gradually discharged, the filter press pump flow gradually reduced, pump head gradually increased; 3, The amount of liquid becomes smaller, the pump tends to small flow, high-lift state, then pay attention to observation, such as the flow rate is less than 30% of the rated flow, the pressure is not stable, to promptly open the return line valve for export liquid Split, so that the pump has remained stable operation
