Analysis of structural characteristics of mechanical steam rotary joints



The steam rotary joint is a steam-flow rotary joint specially designed for corrugating rolls of medium and low speed paperboard production lines. This type of rotary joint is internally supported by oil-free bearings. It is an internal self-supporting rotary joint with simple structure and convenient use. With a spherical sealing structure, due to the frictional torque between the sealing faces, the outside of this type of rotary joint is stopped by a rotation stop lever. Metal hoses must be used for this type of swivel joint and piping connections.
The loop rotary joint can be connected according to the working conditions. The transmission medium inlet can be freely selected to enter the side or the back end depending on the work situation. The sealing surface and the sealing ring are made of special materials, which have long service life, corrosion resistance, wear resistance and no leakage. There are two precision bearings inside the rotary joint, which are sturdy and flexible, stable and long-lasting, and have a small friction coefficient, so they can run at high speed. The condition of the internal seal wear can be visually observed by the appearance of the product, which can prevent mechanical shutdown or mechanical damage to achieve preventive effects and reduce losses. The seals are worn and replaced, and the maintenance is simple. It is not necessary to re-purchase new products and save costs. Single-circuit danhuilu series rotary joints: meet the needs of various industries at home and abroad, fluid medium water (steam), oil (oil), air (Air), vacuum (coolant) cutting fluid (coolant), toluene and other chemistry Solvent.
High-quality rotary joints and precision bearing units on high-rigidity shafts, long-term operation without vibration, the shaft is subjected to special heat treatment to increase rigidity, and the fixed ring seal is made of special material, anti-wear carbon graphite, impervious to water. And the dry operation, especially the size of the rotating closed surface must be reduced to a minimum, even under the higher yali pressure, the long-term mechanical experience of the company has become a better balance of the closed surface part, the RF type rotary joint adopts The bronze retaining ring is intended for use in two hundred high pressures.
