Maintenance-free rotating compensator is introduced
Maintenance-free rotating compensator flexible graphite packing is chosen, heat-resistant - 60 ℃, 800 ℃, adopted by the level of nuclear level, industrial precision level respectively and free maintenance.
Maintenance-free rotary filling, sealing coat, flexible graphite packing, bolts, N pressure spring assembly, packing gland, and the spring compression flange: described packing pressure between flange and pressure on the flange with compression spring, compression flange longitudinal section for u-shaped slot. Within the circle of u-shaped groove and the right end face of catheter between two fixed ring has to match the variable diameter pipe movement of ring rolling ball type.
Maintenance-free rotary compensator packing USES the current domestic most advanced packing, heat-resistant - 60 ℃, 800 ℃, due to the compensator in external and external casing pipe inner weld with baffle ring, hold in reducing the friction between baffle ring (rolling ring) ball, reduced the inner sleeve for packing wear. And because the compensator device more groups of the natural tension of the spring push the gland flange, wear very slight packing forever in a compact state, so that the pipeline leak of liquid or gas medium, when large amounts of packing wear, spring tension can't satisfy adjustment, available outside force to adjust the spring pressure to stop working conditions to achieve the required sealing effect, so this product has overcome other ?
Maintenance-free rotating compensator is the sealing material with pressure tools and molding first, forming density is not too close, keep the plasticity. Then the packing N times to product requirements (destiny) into the packing cavity, add some delay the composition of oxidation, then through hydraulic press second shaped under certain pressure (hydraulic press more than manual wrench in both strength and uniform process), between the packing ring, to improve the density of packing, the packing sealing performance better, make products to ensure no leak in 15 to 20 years.
Maintenance-free compensator for use with variable diameter tube to tube diameter, the media can shun tong, smoothly, solve the above problem. Some similar products made by using variable diameter tube products ? at work
