The failure of the rubber diaphragm of the pulse valve is a common fault of the combined grinding dust collector, which directly affects the cleaning effect. The equipment is an external filter type, and the bag is equipped with a skeleton. It is necessary to check whether the parts fixing the filter bag are loose and the tension of the filter bag is appropriate. Whether the support frame is smooth or not to prevent the wear of the filter bag, compressed air is used to clean the dust, so it is required to remove oil mist and water droplets, and the oil-water separator should be cleaned frequently to prevent the failure of the moving mechanism and the blockage of the filter bag. In use, it is necessary to prevent the gas from cooling below the dew point in the bag room, especially when the bag filter is used under negative pressure, it should be noted that because the shell often leaks air, so that the gas temperature in the bag room is lower than the dew point, the filter bag is It will be damp, so that the dust is not loosely attached to the filter bag, but sticky to the filter bag, blocking the fabric holes, causing the cleaning failure, making the pressure drop of the dust collector too large, and it cannot continue to operate. . To prevent condensation, keep the temperature of the gas in the dust collector and its system at a temperature of 25-35°C higher than its dew point to ensure the good use of the filter bag.
