中文产品介绍：

　　长期以来，3EST125-975 DCC2382A使用接近传感器监测流体膜轴承机器被认为是一种最佳实践。有一些例外情况，比如往复式压缩机曲轴监测，但非常罕见。流体膜轴承中的流体润滑通常会为转子振动提供显著的阻尼，使得振动不会在壳体上被感知。转子在轴承间隙中旋转形成的流体楔形提供了减震效果，并允许转子和壳体之间的相对运动，这使得使用接近传感器成为完美的应用。在某些情况下，如果允许振动幅度足够大，使转子与壳体接触，那么壳体传感器可能会拾取到振动信号。将套管传感器作为监测流体膜轴承机器的主要手段的问题是，传感器提供的信息不足以表明存在某个问题或故障。通常，测量流体膜轴承的套管振动并不提供足够的信息来防止机器损坏。

　　在工业燃气轮机中，3EST125-975 DCC2382A相对于外壳质量来说是很大的，这导致外壳的移动比典型的工业机械更多。对于工业燃气轮机，需要接近传感器来监测转子，同时需要外壳传感器来监测外壳，以实现足够的振动保护和监测。这也可能适用于大型蒸汽轮机，通常功率大于100兆瓦。

　　3EST125-975 DCC2382A来监测由流体膜轴承支撑的往复式压缩机曲轴，原因是轴承支撑结构。在较短的距离内有众多轴承，使系统非常刚性，不允许曲轴和壳体之间有很大的相对运动。由于曲轴和壳体之间的相对运动不多，使用接近传感器监测曲轴振动是不切实际的。

　　3EST125-975 DCC2382A在流体薄膜轴承机器上测量振动、位置、速度和相位，有效地保护了关键资产。无需拆卸机器即可内部窥视的能力对石油和天然气、发电和其他与过程相关的行业来说是无价的。接近系统提供的数据为做出有效的诊断建议提供了必要的ภาพรวม。

英文产品介绍：

For a long time, using proximity sensors to monitor fluid film bearing machines has been considered a best practice for 3EST125-975 DCC2382A. There are some exceptions, such as monitoring the crankshaft of reciprocating compressors, but they are very rare. Fluid lubrication in fluid film bearings typically provides significant damping for rotor vibration, preventing it from being perceived on the housing. The fluid wedge formed by the rotation of the rotor in the bearing clearance provides shock absorption and allows for relative motion between the rotor and the housing, making the use of proximity sensors a perfect application. In some cases, if the vibration amplitude is allowed to be large enough to bring the rotor into contact with the housing, the housing sensor may pick up the vibration signal. The problem with using casing sensors as the main means of monitoring fluid film bearing machines is that the information provided by the sensors is insufficient to indicate the presence of a problem or malfunction. Usually, measuring the sleeve vibration of fluid film bearings does not provide sufficient information to prevent machine damage.

In industrial gas turbines, 3EST125-975 DCC2382A is relatively large compared to the mass of the casing, which results in more movement of the casing than typical industrial machinery. For industrial gas turbines, proximity sensors are required to monitor the rotor, while shell sensors are needed to monitor the shell for sufficient vibration protection and monitoring. This may also apply to large steam turbines, typically with a power greater than 100 megawatts.

3EST125-975 DCC2382A is used to monitor the reciprocating compressor crankshaft supported by fluid film bearings due to the bearing support structure. There are numerous bearings within a short distance, making the system very rigid and not allowing significant relative motion between the crankshaft and the housing. Due to the limited relative motion between the crankshaft and the housing, it is impractical to use proximity sensors to monitor crankshaft vibration.

3EST125-975 DCC2382A measures vibration, position, velocity, and phase on fluid thin film bearing machines, effectively protecting critical assets. The ability to peek inside without dismantling the machine is invaluable for industries related to oil and gas, power generation, and other processes. The data provided by the system provides the necessary information for making effective diagnostic recommendations.
