DN rotary joint

DN type rotary joint The internal structure of the rotary joint is directly supported by high-precision bearings, which plays reciprocating or low-speed rotation. It has high abrasion resistance, flexible rotation, and strong support capabilities. The imported seals are used for the seals, which has reliable sealing performance. .
DN rotary joint, also known as reciprocating rotary joint, also known as pendulum joint swing joint, is a mobile joint dedicated to channel fluid medium between steel pipelines, which is directly supported by balls inside, has good rotation and strong support. Good abrasion resistance, reciprocating swing-type rotary joints have long service life, special rubber materials, both reliable sealing and high temperature resistance, are widely used in metallurgy, petrochemical, shipbuilding, papermaking and other industrial fields.
Connection method: welding, flange, thread
Maximum pressure: 5.0MPa
Maximum temperature: 200 C
Maximum speed: 10rpm
Applicable medium: coolant, various oil products, compressed air
Use of reciprocating rotary joints: Lubricating oil is dripped around the sealing surface where the moving ring and the graphite ring join (to prevent the two pieces from being bonded to damage the graphite ring). If the machine is not used for a long time, the rotary joint seal will be rusted and damaged. If it is reused, it will be stuck or leaked. Swivel joints must be hosed in and out and of sufficient length. The piping and the inside of the roller should be kept clean. New machines often cause abnormal damage to the rotary joint due to the internal cleanliness.
The threads of the rotary joint rotary shaft and the fixed inner tube are left-handed and right-handed. The roller rotates clockwise, using a left-handed threaded rotary joint, and vice versa. The rotation axis of the rotary joint is right-handed, and the thread that fixes the inner tube is also right-handed.
