减速驱动器应用程序的优势

Rotork已在佛罗里达电力与光（FPL）海牛车站安装了型k型阻尼器驱动器。这些产品的好处是它们的迅速行动能力，这是必不可少的。缺乏速度会导致站点和员工的严重风险，而旋转船可以提供满足这些要求的解决方案。

There certainly is no substitute for speed. In nature, on the athletic field or on the computer, superior speed makes all the difference. Pneumatic-powered damper drives are excellent choices for speed sensitive installations. There are no motor windings or gear sets that can compete on pure speed applications the way a quick acting pneumatic drive can react. For combustion air and flue gas applications, some critical services are very dependent on rapid speed to ensure equipment life, operator safety and peak plant performance. At the FPL 3-Unit Manatee Station, a 2,735 MW generating plant in Parrish, Florida, Rotork Type K damper drives have provided a solution to a critical application demanding quick damper operation.

In the case of balanced-draft power generation boilers, low pressure conditions inside the combustion chamber can lead to some very serious equipment failures. Boiler pressure transients can cause combustion issues that lead to irregular heating in the steam tubes. In extreme conditions, excess negative boiler pressure can collapse boiler walls and buckstays, leading to additional catastrophic failures such as ruined boiler tubes and refractory or even wholesale structural damage. The nature of these events often equate to long term unit shutdown, lost kilowatt production, and expensive emergency site construction repairs. Power generation boilers need a somewhat consistent internal operating pressure environment for efficient and manageable combustion. The ID Fans on a combustion boiler play a critical role in maintaining that reliable boiler pressure. The ID Fan Inlet Damper Controls that regulate fan induced pressure and airflow need to be vigilant to help keep these pressure fluctuations in check. The ID Fan Damper Inlet Drives required for the FPL Manatee Station Unit s1 & 2 require full 90 degree drive and damper movement at full torque load in three seconds or less to safeguard the operation of the boilers.

K型“ PM系列”基座安装TK-6阻尼器驱动器以不到三秒钟的测试速度提供5,000磅的扭矩，全90度中风。

停电需要拆除1976年安装的原始现有驱动器，以支持新的k型阻尼器驱动器，用于ID风扇入口阻尼器。每单位有四个ID风扇安装，或在此服务中在海牛车站进行八个驱动器。此后，K型向佛罗里达州东海岸的FPL Martin站提供了四个相同的驱动器。在此位置仍有四个最终驱动器要安装，以便全部完成所有16个ID粉丝。该中断计划于2013年进行。

现有的驱动器已超过30年。此外，它们与该工厂的新DCS系统不兼容，并且手动覆盖在老化的阻尼器驱动器上是不可靠的。

K类型提供了“现场”改造驱动器，该驱动器与现有的阻尼驱动器足迹相匹配，该驱动器范围具有智能定位器技术和集成的空气量助推器，以获得所需的旋转速度。类型K还完成了驱动器上的工厂接受测试，并获得了智能定位器记录的测试周期时间。测试的结果已记录并记录下来，以供FPL在发货之前进行审查。

另一个挑战指出，可以使用铰接的人道门来维修ID风扇，要求将手动卸载手轮旋转到12点钟的位置。键入K为项目经理的满意度设计了解决方案。

The on-site performance testing for damper drive speed was conducted at the power plant early on a Sunday morning at about 2.00am. This was a full load/installed equipment proof-test scheduled typically toward the end of a planned outage. This acceptance test is critical to build confidence in the plant unit trip and boiler shutdown process. The Type K Drives performed as quickly and as smoothly as factory testing had indicated. At full boiler pressure and damper load, the drives rapidly failed to the fully closed position as required. Passing this test is primary to outage completion and full sign-off for boiler readiness to generate electricity. The trip test was witnessed by several key FPL personnel at the control room and by field instrumentation technicians at the ID fans.
