选择旋转接头时应考虑的因素
What to Consider When Selecting Swivel Joints

从消防车到钢厂，旋转接头是各种机械和应用的重要部件。这些部件提供了固定管道或软管与旋转机械部件之间的平滑连接。From fire trucks to steel mills, swivel joints are essential components for all kinds of of machinery and applications. The components provide the smooth connection between stationary pipes or hoses and rotating machinery parts.

设计、工厂和维护工程师在柔性管道系统、装卸臂、软管卷盘、污水管道和污水处理设备以及各种类型的工艺机械中使用旋转接头。他们还使用旋转接头在机床冷却液输送，鼓灌装应用，以及各种工厂流体和干散货输送应用。Design, plant and maintenance engineers use swivel joints in flexible piping systems, loading arms, hose reels, sewer rodding and wastewater treatment equipment, and various types of process machinery. They also use swivel joints in machine tool coolant transfer, drum-filling applications, and in a variety of in-plant fluid and dry bulk transfer applications.

选择旋转接头时应考虑的因素

选择旋转接头Selecting a Swivel Joint

如果机器元件不能移动，- 先进的机器可能会损坏。旋转接头是在很大程度上获得回报的必要投资。它们延长了机器的使用寿命，减少了维护和停机时间。The most advanced machinery can breakdown if the machine elements aren’t able to move. Swivel joints are necessary investments that pay off in a big way. They extend machinery lifetime and reduce maintenance and downtime.

选择旋转接头时，必须遵守制造商的规范。如果不满足要求，很可能会发生泄漏，机械也会失效。It’s extremely important to follow the manufacturer’s specifications when selecting swivel joints. If the requirements aren’t met, it’s likely that leakage will occur and the machinery will fail.

您还必须了解给定应用程序的设计参数。压力、温度和支撑重量等因素对正确选择旋转接头都起着至关重要的作用。另一个必须考虑的关键因素是流体本身的腐蚀性。You must also understand the design parameters of a given application. Things such as pressure, temperature and supported weight all play an essential role in properly selecting a swivel. Another key factor that must be taken into consideration is the corrosiveness of the fluid itself.

应用环境对于选择正确的旋转接头至关重要。通过仔细考虑流体的化学成分、温度和外部环境，您可以缩小旋转接头的范围。The application environment is critical to selecting the right swivel joint. By carefully considering the fluid’s chemical composition, its temperature and the external environment, you’ll be able to narrow in on the perfect swivel joint.

选择是无止境的The Options are Endless

考虑到尺寸、密封件和连接件的潜在组合（更不用说金属），旋转接头的宽度是无限的。这些金属包括碳钢、不锈钢、黄铜、铝、青铜和球墨铸铁。The breadth of swivel joints is endless when you consider the potential combinations of sizes, seals, and connections, not to mention metals. These metals include carbon steel, stainless steel, brass, aluminum, bronze and ductile iron.

多功能性是任何有效旋转接头的关键，因为规格可能因工作和所需功能的不同而大幅变化。Versatility is the key to any effective swivel joint as specification can vary drastically depending on the job and functionality required.

旋转接头有一个、两个和三个旋转平面，几乎可以实现无限的灵活性。金属和密封材料的标准组合包括压力、温度、耐腐蚀性和承载能力，完全在大多数应用要求的范围内。端部连接的列表也很广泛。螺纹（NPT）、法兰（150/300 ANSI）和对焊端是- 常见的。Swivel joints are available in one, two and three planes of rotation for virtually unlimited flexibility. Standard combinations of metals and seal materials cover pressures, temperatures, corrosion resistance and load bearing capacities, well within the limits of most application requirements. The list of end connections is also extensive. Threaded (NPT), flanged (150/300 ANSI) and butt-weld ends are some of the most common.

下面简要介绍一些- 常用的旋转接头，以及它们如何影响横跨多个行业的有效流体流动。Here’s a quick look at some of the most used swivel joints and how they impact the effective flow of fluids across an array of industries.

装卸臂更换旋转接头Loading Arm Replacement Swivels

装卸臂系统允许通过柔性管道系统将液体或液化气输送到油罐车或轨道车中。有些应用程序需要一个加载臂通过顶部连接进行加载，而其他连接点位于底部。Loading arm systems allow the transfer of fluids or liquefied gas into a tank truck or rail car through a flexible piping system. Some applications require a loading arm to load through a top connection, while other connection points are at the bottom.

多年来，装卸臂旋转接头的功能不断发展，以满足流体处理解决方案的需求。无论应用涉及油罐车、轨道车、圆桶或手提袋，以及石油产品、液化气、沥青、溶剂或危险/腐蚀性化学品的移动，转环都是这一过程中不可或缺的一部分。The functionality of loading arm swivel joints has evolved over the years to meet the demands of fluid handling solutions. Whether the application involves tank trucks, railcars, drums or totes, and the moving of petroleum products, liquefied gases, asphalt, solvents or hazardous/corrosive chemicals, swivels play an integral part in the process.

软管卷盘用旋转接头Hose Reel Swivels

旋转接头是许多软管卷盘应用的一个组成部分，并且有许多专门为软管卷盘设计的部件。此外，还可以定制软管卷盘旋转接头，以适合您的特定应用。Swivel joints are an integral part of many hose reel applications and there is a large variety of these parts designed specifically for hose reels. In addition, there’s the ability to customize a hose reel swivel to fit your specific application.
