Spiral Labyrinth Seal

Spiral labyrinth seal is used in industry long ago, and it is different from the spiral seal in that: the axis of the helical groove machined surface , the holes in the sealing collar is made also vehicles , and has opposite the shaft screwed to the shaft and screw suites stark turbulent flow . Additionally , labyrinth seal spiral screw velocity higher than the sealing screw , which turbulent flow conditions for low viscosity liquids. cable marker ties Spiral laminar flow conditions generally used for sealing large -viscosity liquid ( such as viscosity liquids than water ) .
How it works: In between the screw and the threaded sleeve work space, the liquid in the collar two tooth surfaces and screw two tooth surfaces bounded by a number of cellular space . Screw and the gap between the threaded sleeve surface was grooved annular cylinder . Fluid through the vortex formed when the threads , the direction of flow in the opposite direction . As the screw fluid flow around a momentum exchange results , security seals screw the energy to liquid. Helix and threaded sleeve with the liquid interaction that results in through the gap between the screw and the threaded sleeve surface frictional force is generated in the name of boundaries . Friction generated by the liquid in between the screw and the threaded sleeve pressure .
