I. Cyclone quality of industrial dust collector The quality of cyclone is mainly the length of cyclone inlet and the length of cyclone top to boss surface. The failure rate is 51.7% and 21.O% respectively. The main cause is that the cyclone cannot be interchanged during installation and affects the flatness of the installation, causing air leakage and reducing the aerodynamic performance of the whole machine.
Second, the quality of the flange of the industrial dust collector flange is an important part of the cyclone dust collector, its main failure items are the deviation of the diameter of the center circle of the circular flange screw inspection hole, the distance between any two adjacent bolts on the same side of the rectangular flange The deviation of the two diagonal lengths of the square rectangular flange and the deviation of the inner diameter of the circular flange are 50.0%, 47.0%, 32.7%, and 23.3%, respectively. As a result, the dust removal efficiency and air leakage rate are affected.
Third, the assembly quality of the whole machine In terms of the assembly of the whole machine, the axis parallel deviation of the axis parallel parts is a relatively important installation index, the failure rate is 26.7%. Also. In terms of paint and welding quality, there are also uneven paint on the surface of the dust collector, and the welding seam is not straight, which affects the appearance quality of the dust collector;
