5464-674? 渦輪設備 數(shù)字控制系統(tǒng)來調節(jié)其速度或性能
5464-674 是一種渦輪設備,它使用數(shù)字控制系統(tǒng)來調節(jié)其速度或 性能。與傳統(tǒng)的機械或模擬控制系統(tǒng)相比, 5464-674 具有更高的準確性、更快的響應速度和更好的 適應性。
這 5464-674 的核心是電子控制單元 (ECU) 或微處理器,即 負責監(jiān)控汽輪機的運行狀態(tài)并自動 根據預設的控制算法調整渦輪機的速度或功率輸出 或操作員輸入。通過數(shù)字控制系統(tǒng),精確控制 可以實現(xiàn)燃油流量和氣流等參數(shù),從而實現(xiàn) 渦輪機性能的精確調節(jié)。
這些控制裝置可用于正向或反向作用應用,也可用于單個或串聯(lián)執(zhí)行器。
提供三種不同執(zhí)行器電流范圍的型號,以及高壓型號(90 至 150 Vdc 或 88 至 132 Vac,45 至 440 Hz)
和低壓型號(20 至 40 Vdc)。高壓型號在正面被標識為這樣;低壓模型則不然。
在反向作用系統(tǒng)中,當執(zhí)行器電壓降低時,執(zhí)行器需要更多的燃料。
執(zhí)行器的電壓完全損失將驅動執(zhí)行器充滿燃料。
這允許備用機械球頭調速器進行控制,而不是像直動式系統(tǒng)那樣關閉原動機。
還提供可選的減速坡道。

5464-674
The 5464-674 is a turbine device that uses a digital control system to regulate its speed or performance. Compared to traditional mechanical or analog control systems, the 5644-674 offers higher accuracy, faster response and better adaptability.
At the heart of this 5644-674 is the electronic control unit (ECU) or microprocessor, which is responsible for monitoring the operating state of the turbine and automatically adjusting the turbine’s speed or power output or operator input according to a preset control algorithm. Through the digital control system, precise control can achieve parameters such as fuel flow and airflow, thus achieving precise regulation of turbine performance.
These controls can be used in forward or reverse action applications, as well as single or series actuators.
Models available in three different actuator current ranges, as well as high-voltage models (90 to 150 Vdc or 88 to 132 Vac, 45 to 440 Hz)
And low-voltage models (20 to 40 Vdc). High-pressure models are identified on the front as such; Low pressure models do not.
In a reverse-acting system, when the actuator voltage is reduced, the actuator requires more fuel.
A complete loss of voltage in the actuator will drive the actuator to full fuel.
This allows the standby mechanical ball-head governor to be controlled, rather than turning off the prime mover as in direct-acting systems.
Optional deceleration ramps are also available.
