Rotary joint is used in equipment on dryer cylinders to transport and discharge steam or hot oil, ensuring that the dryer cylinder can efficiently transfer heat and improve the drying efficiency of paper.
Rotary joints must operate stably under high temperature, high speed and pressure fluctuations. Therefore, rotary joints need to have high sealing and high temperature corrosion resistance to ensure production efficiency and the service life of the dryer cylinder.
Specific functions of rotary joints in dryer cylinders:
(1) Steam transportation: Steam is introduced into the dryer cylinder through the rotary joint to heat the surface of the dryer cylinder and accelerate the drying of paper.
(2) Condensate discharge: The rotary joint discharges condensate inside the dryer cylinder through a siphon to improve the utilization rate of steam.
(3) Maintain pressure balance inside the dryer cylinder to ensure stable operation.
(4) Improve heat conversion efficiency, reduce steam waste and reduce drying costs.
Features of rotary joints:
(1) High temperature and high pressure resistance, suitable for high temperatures of 150° to 250°, and can withstand steam pressures of 10 Bar and above.
(2) High sealing performance, using graphite or antimony-containing graphite seals to prevent leakage and reduce energy consumption.
(3) Save energy and reduce consumption, optimize steam transmission and condensate discharge, and improve energy utilization.
(4) Low friction design, reduce wear and increase service life.
