The composition of welding workshop dust catcher

Welding workshop dust catcher of welding workshop dust rigid impeller impeller rigidity is made up of shaft and rotor. Vane and rotor casting into a whole. Due to casting blades without flexibility, therefore and shell rotary cavity wall must leave appropriate gap, sealed performance is poor. Impeller rotor by sliding bearing end cover. Flexible impeller vane and rotor radial one Angle, therefore can only turn in one direction, shall not be reversed. If you want to reverse, impeller head must be installed within the cabinet. Rigid impeller blade is according to the rotor radial layout, and with the machine 売 clearance, so it can be arbitrary and reverse rotation. Welding workshop dust end sealing end of rotary discharge valve sealing has two forms. One is put friction between cover and impeller rotor end ring ( Or the friction plate, friction plate) ; This kind of form for more flexible impeller structure. The other is a set packing on the outside of end cover sealing device; At this point supporting impeller rotor sliding bearing will no longer be directly on the end cover, but to the lateral move, can be set up independent stent combined with end cover, also can by jin & throughout; With the end cover a whole structure. This form used in rigid impeller structure.
