Install the venturi should pay attention 
 Venturi tube known as the patron saint of the dust collector bag, the dust removal equipment back to blowing the cleaning process, the venturi tube to the dust collector bag to force uniform, thorough cleaning, the effective dust collection efficiency and dust collector service life. 
 Venturi pipeline wherever possible bell configuration, to avoid unnecessary deviation or staggered, as well as depression and cause the air bag. Venturi pipeline arrangement should remain parallel, as well as the appropriate slope and the beams and the floor surface, the tendency discharge or exhaust position, set aside space for the installation of insulation materials, and to consider the maintenance pathway of the valve and pipe fittings, such as dust collector filter bags are not exposed premises, shall be reserved for the access door (hole), its size should be consistent The relevant national regulations. 
 The venturi tube installed pipeline must be able to allow expansion or contraction stress in the pipes, joints or connected equipment. 
 (1) venturi pipeline combination of manufacturing should be considered in order to minimize site welding principle. 
 (2) manufactured the venturi tube pipelines, transported to the site be norms to be cleaning, cleaning thick steel plate and tube-side applications to be the spot to cover the final welding, shall not be removed. 
 (3) Venturi tube rings, you should use the same material as the tube. 
 (4) the venturi pipe cutting machine or tube cutter, fracture rasp or scraper flat file.
