General information.
Rotary pressure joints (rotational or rotary couplings, rotary union, swivel, hydrohinge) – these are high-precision mechanical parts the carrying-out passing or supply of liquid (water, oil, lubricant cooling liquids) or gas (steam) in the rotating equipment nodes.
Universal rotary pressure joints are applied in the most different industries: pulp and paper industry, textile industry, production of rubbers, food, pharmaceutical both chemical industries, metal working, and power.
The main detail of rotary pressure joints – mechanical seal, it has to maintain a high pressure, at the same time rotating with a high speed. For providing
hermetic sealing and long life, contacts of consolidation are made of high-strength materials, proceeding from conditions and the environment of work. Tungsten coal-graphite / carbide
finds the general application in moderately severe operating conditions. In chemically aggressive working fluid application of mechanical seals from silicon carbide is recommended.
The spring of a mechanical seal presses friction pair rings to each other, pressurizing connection during a stop. In the course of work the clip is carried out by hydraulic pressure, except for cases of low working pressure or vacuum.
The right choice of a mechanical seal is decisive for effective work of rotary pressure joint as in case of failure of a mechanical seal and leakage of the environment in considerable
degrees efficiency of process of cooling or heating in general decreases.
The main criteria of the choice a rotary pressure joint are equipment type where connection and the given environment is used. Rotary pressure joints can be equipped with bearings,
connect a rotor and the case one or several bearings, or not to have own bearing, in this case during the work the spindle bearing is used.
Design of rotary pressure joints.
The design of our rotary pressure joints provides fast and simple replacement of mechanical seals that provides them high maintainability and reduces expenses of idle time and repair of the equipment. All details are made of stainless steel that provides high corrosion resistance. The reliable mechanical seal ensures functioning in the mode of high temperatures, and also long life cycle.The design depends on the direction of a flow of the given environment whether the movement in one or two directions is carried out.
Universal rotary pressure joints has the broad range of application (for water, air, oils, chemically hostile environment), for the different equipment in many industries.
The AvtokomTehnolodgy group of companies is the official representative of producer the rotary pressure joints Kroma Ltd (Serbia). We deliver rotary pressure joints for the different equipment with a one-sided and bilateral flow, for work in different environments. Analogs of such producers as DEUBLIN, MEIER, ROTOFLUX, DUFF NORTON, KADANT JOHNSON, JOHNSON FLUITEN are also ready to offer excellent quality at reasonable price.
Our specialists will select matching mechanical seals or analog of mechanical seal for pump in the catalog.
