The main technical development of industrial dust collector manufacturing
main technical requirements for the production of industrial dust collectors
are: the castings used for dust collectors must not have cracks, shrinkage holes, slag holes, insufficient pouring, and other defects that reduce the strength or have the appearance of root duster. The welding seam of the structure of the dust collector shall be straight, without burn-through, cracks, pores, slag inclusion, and non-fusion defects. After welding, the residues such as welding and spatter should be removed. The fillet height of fillet welds shall not be less than the thickness of the thinner base metal. The inner and outer surfaces of the dust collector housing should be smooth and uniform, with a uniform arc, and the allowable deviation of its outer diameter or external dimensions is 5%. The splicing of the dust collector housing should be flat, and the longitudinal seams should be staggered. The flange connection and the place where the inspection door is installed should be tight. The allowable air leakage rate of the dust collector under the design working pressure is 5%, of which the centrifugal dust collector is 3%. The
main advantages of industrial dust collectors
are: simple structure, large volume, safe and reliable, high purification efficiency, etc. It mainly increases its negative pressure through high-pressure fans, air pumps and other equipment. Strong.
The shape of industrial vacuum cleaners is selected according to their needs. In general, the common shapes of industrial vacuum cleaners are mainly: barrel, square, calf models and simple brackets.
With the development of science and technology, industrial vacuum cleaners are constantly changing. At present, it mainly uses mobile vehicles and rocker-type dust cleaning devices, which greatly improves the environmental protection.
