Principle of Labyrinth Seal ：

When the piston of labyrinth compressor worked, gas flow from high pressure side to the lower side, pressure transferred into kinetic energy at pitch point, most kinetic energy of gas flow transferred into pressure and vortex energy due to the increasing volume when the gas flow entered chamber with high speed. The vortex energy shall be lost by the type of thermal energy. Energy and pressure decreased when gas flow pass through some small labyrinth compartments, it can meet seal effect if there are sufficient compartments and the pressure of lower pressure sides are equal.

Features of Labyrinth Compressor ：

1.Non-contacted seal structure—between piston and cylinder, packing and piston rod
2.Oil free—lube oil of cylinder inside is not necessary
3.Non-pollution —gas does not contact lube oil, friction-free between piston and cylinder, no abrasive dust
4. No quick-wear parts within cylinder—piston ring, rider ring
5.Non-leakage —it can achieve full seal of complete unit

6.Reliable and long running period — spare compressor is not necessary
7.High adaptation —it’s suitable for all kinds of gases, corrosive gas or particles included.
8. Safety — flammable, explosive ,corrosive and harmful to environment or health are all not allowable
9.Vertical structure, reasonable layout, space-saving
