Technical requirements for rotary joint parts

Time: 2019-12-19 11:38 Author: admin Hits: Times
Technical requirements for rotary joint parts:
1. The surface of the casting of the rotary joint housing should be clean, and the inner and outer surfaces should be smooth and smooth. There should be no flashes or burrs in the hand. There should be no leakage for 10min.
2. Rotary joints with high-temperature heat-conducting oil medium. The sealing surface material is a casting that requires low-temperature annealing to remove stress.
3. Surface accuracy and roughness requirements of rotary joint seals:
When the sealing surface is flat: the flatness of the flat surface is less than 0.0009mm
Its surface roughness Ra≤0.4μm
When the sealing surface of the rotary joint is spherical: its spherical degree should be ≤ ± 0.01mm
Its surface roughness Ra≤0.4μm
4. Sealing ring rotary joint The graphite sealing ring must be tested for leakage (1.25 times the design pressure), and it can be used without leakage. Others are according to JB / T8872 standard.
