XHDS-3401 High temperature water rotary joints

The XHDS type high-temperature water rotary joint adopts a brand new appearance, mechanical seal combination, and durable ball milled cast iron made of spherical graphite, which has high strength and flexibility, improving the mechanical properties of cast iron. The ceramic ring is made of imported silicon carbide ceramics, which have high resistance to pressure, are not easily bent, have finer density, lower thermal expansion probability, and are more stable to use

The hollow shaft of the XHDS new high-temperature water rotary joint is connected to the roller or roll through threads or flanges, and is the main rotating component that moves synchronously with the equipment. The sealing ring, hollow shaft, and corrugated compensator together form a floating double end face sealing friction pair, which is beneficial for reducing the disadvantages of poor sealing caused by poor concentricity of the equipment. The sealing ring is made of impregnated carbon graphite, which has good lubricity, thereby reducing friction and wear and improving service life; With the wear of the sealing ring, the bellows compensator is compensated at any time by the pressure of the spring. The use of bearings not only plays a manufacturing role, but also improves rotational accuracy and reduces friction torque. In addition, there are observation holes on the shell, through which the wear and sealing condition of the sealing ring can be observed at any time. Regularly add lithium grease during high temperatures.

High temperature water rotary joint is a key sealing device used to transport fluid media from fixed pipelines to rotating or reciprocating equipment, especially suitable for transporting high-temperature hot water, steam and other media. In industrial production, such as papermaking, textile printing and dyeing, rubber and plastics, steel metallurgy, and food drying, high-temperature water is widely used as a heating or cooling medium. Rotary joints play a central role in connecting stationary pipelines and rotating components (such as dryers and drums) during this process.

The rotary joint for high-temperature water belongs to the fluid dynamic sealing device, and its core function is to achieve continuous transmission of the medium under 360 ° rotation. It uses an internal balanced end face sealing structure to push the sealing ring (such as graphite ring, silicon carbide ring, etc.) with spring pre tension force, so that its plane is tightly adhered to the hollow shaft end face, forming the main seal. This design can automatically compensate for the wear of the sealing surface, ensuring good sealing performance under high temperature and high pressure conditions, and preventing medium leakage.
