Q:Dust filter bag cell plate hole size installation should pay attention to? A:1 .Cell plate hole size both to bear the negative pressure system , but also bear bag , dust bag cage floor and the weight , if any flower plate deformation may affect the sealing effect of the bag and the heavy bag at the straightness of the design in the flower lower plate should be done to strengthen the process . 2.Cell plate hole size should spend smooth, there should be no deflection , different irregularities and other defects, its flatness deviation is less than the length of the plate flower 2/1000 . Flower plate surrounding the aperture required to be smooth burr-free , elastic expansion ring fixed aperture plate flower bag tolerance of ± 0.3mm. Mounting position and the theoretical position deviation after flowering plate aperture processing should be less than 1.5mm. Flatness deviation is less than the length of the plate flower 2/1000 .
