選擇旋轉(zhuǎn)接頭時(shí)應(yīng)考慮的因素
What to Consider When Selecting Swivel Joints
從消防車到鋼廠，旋轉(zhuǎn)接頭是各種機(jī)械和應(yīng)用的重要部件。這些部件提供了固定管道或軟管與旋轉(zhuǎn)機(jī)械部件之間的平滑連接。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.
設(shè)計(jì)、工廠和維護(hù)工程師在柔性管道系統(tǒng)、裝卸臂、軟管卷盤、污水管道和污水處理設(shè)備以及各種類型的工藝機(jī)械中使用旋轉(zhuǎn)接頭。他們還使用旋轉(zhuǎn)接頭在機(jī)床冷卻液輸送，鼓灌裝應(yīng)用，以及各種工廠流體和干散貨輸送應(yīng)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.
選擇旋轉(zhuǎn)接頭時(shí)應(yīng)考慮的因素
選擇旋轉(zhuǎn)接頭Selecting a Swivel Joint
如果機(jī)器元件不能移動(dòng)，- 先進(jìn)的機(jī)器可能會(huì)損壞。旋轉(zhuǎn)接頭是在很大程度上獲得回報(bào)的必要投資。它們延長了機(jī)器的使用壽命，減少了維護(hù)和停機(jī)時(shí)間。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.
選擇旋轉(zhuǎn)接頭時(shí)，必須遵守制造商的規(guī)范。如果不滿足要求，很可能會(huì)發(fā)生泄漏，機(jī)械也會(huì)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.
您還必須了解給定應(yīng)用程序的設(shè)計(jì)參數(shù)。壓力、溫度和支撐重量等因素對(duì)正確選擇旋轉(zhuǎn)接頭都起著至關(guān)重要的作用。另一個(gè)必須考慮的關(guān)鍵因素是流體本身的腐蝕性。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.
應(yīng)用環(huán)境對(duì)于選擇正確的旋轉(zhuǎn)接頭至關(guān)重要。通過仔細(xì)考慮流體的化學(xué)成分、溫度和外部環(huán)境，您可以縮小旋轉(zhuǎn)接頭的范圍。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.
選擇是無止境的The Options are Endless
考慮到尺寸、密封件和連接件的潛在組合（更不用說金屬），旋轉(zhuǎn)接頭的寬度是無限的。這些金屬包括碳鋼、不銹鋼、黃銅、鋁、青銅和球墨鑄鐵。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轉(zhuǎn)接頭的關(guān)鍵，因?yàn)橐?guī)格可能因工作和所需功能的不同而大幅變化。Versatility is the key to any effective swivel joint as specification can vary drastically depending on the job and functionality required.
旋轉(zhuǎn)接頭有一個(gè)、兩個(gè)和三個(gè)旋轉(zhuǎn)平面，幾乎可以實(shí)現(xiàn)無限的靈活性。金屬和密封材料的標(biāo)準(zhǔn)組合包括壓力、溫度、耐腐蝕性和承載能力，完全在大多數(shù)應(yīng)用要求的范圍內(nèi)。端部連接的列表也很廣泛。螺紋（NPT）、法蘭（150/300 ANSI）和對(duì)焊端是- 常見的。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.

裝卸臂更換旋轉(zhuǎn)接頭Loading Arm Replacement Swivels
裝卸臂系統(tǒng)允許通過柔性管道系統(tǒng)將液體或液化氣輸送到油罐車或軌道車中。有些應(yīng)用程序需要一個(gè)加載臂通過頂部連接進(jìn)行加載，而其他連接點(diǎn)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.
多年來，裝卸臂旋轉(zhuǎn)接頭的功能不斷發(fā)展，以滿足流體處理解決方案的需求。無論應(yīng)用涉及油罐車、軌道車、圓桶或手提袋，以及石油產(chǎn)品、液化氣、瀝青、溶劑或危險(xiǎn)/腐蝕性化學(xué)品的移動(dòng)，轉(zhuǎn)環(huán)都是這一過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.
軟管卷盤用旋轉(zhuǎn)接頭Hose Reel Swivels
旋轉(zhuǎn)接頭是許多軟管卷盤應(yīng)用的一個(gè)組成部分，并且有許多專門為軟管卷盤設(shè)計(jì)的部件。此外，還可以定制軟管卷盤旋轉(zhuǎn)接頭，以適合您的特定應(yīng)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.
雙分體法蘭旋轉(zhuǎn)接頭Dual Split Flange Swivels
