Rotary joints or rotary unions are rotary sealing devices that connect rotating equipment to fixed pipes so that transfer of water, coolant, steam, thermal oil, hydraulic oil, or any other media can be achieved.
Steam rotary union manufacturers in india offer rotary joints that can be designed with multiple passes, and they can handle multiple media types simultaneously.
A soft seal like an O-ring in these cases is used for preventing fluids from “passing” to another passage. These soft seals multi-pass rotary heads are used in a wide range of industrial applications.
Some examples of these applications, are oils and gases, robotics, medical devices, beverages, aerospace, and so on.
Sometimes, in some applications these rotary joints are equipped with slip rings to transfer hydraulic powers and electrical signals.
It is essential to pick the right rotary union manufacturer by checking the quality and experience first. These rotary unions manufacturers guarantee quality products that not only fulfill but surpass the needs and expectations of the customer.
What is a Rotary Steam Joint and how does it work?
Conventional steam rotary joints have a spring-loaded mechanical seal, which prevents the liquid or gaseous medium from dispersing into the atmosphere.
Spring pressure is used for achieving tightness in applications where there is low pressure or vacuum. In a typical rotary joint, the carbon is spring-pressed into a seal, silicon carbide, or any other hard metal.
Thus, you achieve a good, basic mechanical seal structure and a dynamic seal.
A balanced mechanical seal structure is generally used in rotary heads. The Balanced mechanical seal technology relies on the concept of optimizing the spring pressure to create a positive pressure inside the rotary head.
The working pressure of the fluid does not have any little effect on the spring pressure. A balanced mechanical seal is a flat-faced seal. Its swivel heads are supported by ball bearings.
The quality of a rotary joint depends on the quality of the mechanical seal inside. If the quality is poor, then it wears out faster. Thus, you will need more maintenance and downtime. Also, you will have to spend more money on repair costs. With higher repair and maintenance, downtime of the machine increases.
When a seal fails, the efficiency of the cooling or heating process drops when the fluid escapes.
Considering all these factors, the actual replacement of the mechanical seal or rotary joint should be done after considering all aspects.
