Engineered Solutions for Rotary Applications
旋转应用的工程解决方案
旋转接头
旋转接头，也称为旋转接头或旋转接头，将静态供应的流体传输到旋转机械中，例如由油加热或用水冷却的旋转鼓。不同类型的旋转接头用于满足不同的需求。
在工业化世界中广泛使用
旋转接头允许水、空气、液压油、金属加工液、液压油、蒸汽、真空和各种其他介质通过。它们可以安装在旋转轴的末端或周围。

压力接头 Pressure Joints
压力接头通过介质压力密封，并配有强力弹簧以在启动或非常低的压力下保持密封在一起。这种经典技术需要相对较大的扭矩，仅适用于相对介质低压力（<250 psi 或 17 bar）。
塑料密封件 Plastomeric Seals
塑性旋转接头使用定制或商业上可用的“软密封”，由特定应用的聚合物或弹性体制成。它们最适合用于间歇旋转和压力的应用。尽管紧凑，这些密封件表现出显著的扭矩、发热量和磨损率。
静液压密封 Hydrostatic Seals
静液压旋转接头采用精确的公差，在高压力下提供无接触密封，延长使用寿命并减少维护。旋转元件悬浮在不断循环的流体薄膜上，流体流量极低。流体剪切限制了这些接头的最大速度为几千转每分钟。
机械密封 Mechanical Seals
机械密封旋转接头通过有意平衡流体动力学力，最小化密封磨损、扭矩和热生成。平面度必须控制在微米范围内，并根据所需的转速、压力和介质使用不同的密封材料。这些接头即使在压力>140 bar和速度>40,000 RPM的情况下也能可靠地运行。机械密封接头可以根据机器的运行条件变化而进行不同的设计。

Rotary Union
Rotary Unions, also called rotary unions or rotary joints, transfer fluid from a stationary supply into rotating machinery, such as a spinning drum heated by oil or chilled by water. Different types are used to match each set of requirements.
Used throughout the industrialized world
Rotary unions allow the feedthrough of water, air, hydraulic, metalworking fluids, hydraulic oil, steam, vacuum and a variety of other media. They can be installed at the end of or around a rotating shaft.
Pressure Joints
Pressure joints are sealed by media pressure, with a strong spring to keep seals together at startup or very low pressures. This classical technology requires a relatively large amount of torque and is suitable only for relatively media low pressures (<250 psi or 17 bar)
Plastomeric Seals
Plastomeric rotary unions use custom or commercially available “soft seals” made from application-specific polymers or elastomers. They are most suitable for applications with intermittent rotation and pressure. Though compact, these seals exhibit significant torque, heat generation, and wear rates.
Hydrostatic Seals
Hydrostatic rotary unions deploy precise tolerances to provide no-contact sealing at high pressures, extending life and minimizing maintenance. The rotating element is suspended on a fluid film that circulates continuously at a very low flow rate. Fluid shearing limits the maximum speed of these unions to a few thousand RPM.
Mechanical Seals
Mechanical seal rotary unions minimize seal wear, torque, and heat generation through intentional balancing of hydrodynamic forces. Flatness must be controlled within microns, and different seal materials are employed according to the desired RPM, pressure, and media. These unions perform reliably even at pressures >140 bar and speeds >40,000 RPM. Mechanical seal unions can be engineered to behave differently as the machine's operating condition changes.
Rotary Unions
Deublin - The world's largest manufacturer of ROTARY unions
Rotary unions are mechanical devices that allow transfer of pressurized fluid from a stationary source into rotating machinery for heating, cooling or transfer of fluid power. Deublin rotary unions can supply water, steam, compressed air, cooling lubricants, hydraulic and thermal oils, and other media across a wide range of pressures, speeds, and temperatures. Deublin rotary unions are used worldwide in the manufacture of steel and aluminum products, semiconductor products, renewable energy, automotive, machine tool and printing press products, paper and corrugated board manufacturing, and many other everyday products.
The areas of application for slip rings are comparable. They transmit electrical power, control signals and high-speed data streams to and from a rotating machine part. Electrical slip rings are found in almost all automation systems and have a critical impact on equipment functionality, performance and reliability. Slip rings and rotary unions are often used in combination to control and monitor a variety of industrial processes.
Deublin is the world's largest manufacturer of rotary unions. The company has manufacturing facilities, sales offices and warehouses in 15 countries and on four continents. In addition, it has a global distribution network operating from more than 60 countries. Deublin's original product and competence portfolio has grown continuously. Today, it also includes steam joints, swivel joints and electrical slip rings, among others.
In 1945, the success story began with a small workshop operation. Today, Deublin stands for a comprehensive portfolio of field-proven precision products manufactured in state-of-the-art production plants worldwide. Thanks to its global development organization, the company offers a wide range of products and solutions for various manufacturing applications. Also with its long tradition of patented innovations, Deublin delivers decisive advantages in the form of higher performance, reliability and flexibility.
