ROTARY JOINT INSTALLATION AND SPARE PARTS REPLACEMENT The application of JOHNSON-FLUITEN rotary joints is simple and reliable when carried out according to the herebelow described procedures. CONNECTION 1. Use only flexible hoses for stationary part connection to avoid overloading of the roller bearings support. 2. Put the RJ housing in a clamp to tighten the fittings. 3. Use flexible hoses of adequate length in order to have good flexibility. 4. Very long rotating syphon pipes can overload the rotary joint bushing. 5. Rotating syphons should have a good concentricity with the joint rotational axis.For speeds higher than 1000 rpm an additional bushing, made in PTFE or similar antifriction material, should be provided in the machinery. 6. Clean carefully the machinery lines connected with the rotary joint. NO FRICTION TORQUE JOHNSON-FLUITEN Rotary joints have reduced friction torque (see also diagram on page 5); in any case suitable antirotation devices must be implemented to avoid rotation of the stationary part. • For sizes up to R050 flexible hoses generally give a sufficient reaction. • For larger sizes the use of the antirotation pin (see pages 8 & 9) is recommended. SPARE PARTS For all sizes a spare parts kit is available. Each kit consists of: • Stationary and rotary rings • Secondary seals (O-Rings) • Springs NOTE: For sizes R009 & R012 the entire rotor must be replaced YES NO 7. In case of abrasive products the use of seal faces in hard materials (Silicon carbide vs. Tungsten carbide – Arrangement C) is recommended. Dry-running is not allowed with this seal faces material combination. 8. For safety reasons it is recommended to shield the Rotary Joint with suitable barriers to avoid that people could be harmed by accidental dangerous emissions. YES NOTE Avoid using the rotary joints in conditions in which pressure, speed and temperature are simultaneously near to the max. allowed values. For high duty operating conditions a correct selection of seal materials is recommended. In doubt, please contact JOHNSON-FLUITEN. Seal faces are lapped with a planarity of two optical fringes (monocromatic light method). QRD system (see page 5) gives the possibility to check seal element conditions facilitating the maintenance schedule. Rotary joints up to R050 size have pre-lubricated roller bearings which do not require relubrication. Rotary joints RH version, recommended for temperatures higher than 100C, have roller bearing of special design for high temperatures and require periodic relubrication (grease with drip point at 250C or higher, SILEX PLS.2 or equivalent). For this operation a lubricator is provided on joint support. For sizes larger than R050 a lubricator is always provided.
