這些控制裝置可用于正向或反向作用應用,也可用于單或串聯致動器。可提供三種不同致動器電流范圍的型號,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)。高壓模型在正面識別為高壓模型;低壓型號不是。在反作用系統(tǒng)中,當執(zhí)行器電壓降低時,執(zhí)行器需要更多燃油。執(zhí)行器完全失壓將驅動執(zhí)行器充滿燃油。這允許備用機械球頭調速器控制,而不是像直接作用系統(tǒng)那樣關閉原動機。還提供可選減速坡道。當存在此選項時,從額定轉速過渡到怠速的時間約為20秒。如果此選項不存在,則會立即發(fā)生。表1-1和1-2顯示了所有9905/9907系列2301A負載共享和速度控制的零件號和特性。反向作用控制裝置的外部接線與直接作用控制裝置的接線相同。原動機轉速和傳感器輸出頻率之間的關系用以下公式表示:傳感器頻率(Hz)等于轉速傳感齒輪上的齒數乘以額定原動機轉速(單位:轉數/分鐘)除以60。伍德沃德或其任何授權經銷商或代理商的應用工程師隨時可以幫助您為系統(tǒng)選擇正確的控件,或回答有關控件安裝、操作或校準的問題。聯系方式見第6章。參考以下出版物包含有關負載共享和速度控制以及相關部件的其他產品或安裝信息。技術手冊標題25070《電子調速器安裝指南》26260《控制原理和電源管理》82384 SPM-A同步器9905-002 82510《電子控制用磁性拾音器和接近開關》82715《電子控制、印刷電路板的處理和保護指南》,和模塊產品規(guī)范標題82383 SPM-A同步器82390 2301A負載共享和速度控制(9905系列)82516 EG3P/6P/10P執(zhí)行器82575 EGB1P/2P調速器/執(zhí)行器



These controls are available for forward- or reverse-acting applications, and for use with either single or tandem actuators. Models for three different actuator current ranges are available, as well as a high-voltage model (90 to 150 Vdc or 88 to 132 Vac, 45 to 440 Hz), and a low-voltage model (20 to 40 Vdc). The high voltage model is identified as such on the front; the low voltage model is not. In reverse-acting systems, the actuator calls for more fuel when the actuator voltage decreases. Complete loss of voltage to the actuator will drive the actuator to full fuel. This allows a backup mechanical ballhead governor to take control rather than shut down the prime mover as would a direct-acting system. An optional deceleration ramp is also offered. When this option is present, the time to ramp from rated speed to idle speed is approximately 20 seconds. If this option is not present, this happens instantly. Tables 1-1 and 1-2 show part numbers and features of all 9905/9907 series 2301A load sharing and speed controls. External wiring connections for reverse-acting controls are identical to those for direct-acting controls. The relationship between prime mover speed and sensor output frequency is expressed in the formula: Sensor Frequency in Hz equals the number of teeth on the speed sensing gear times the rated prime mover speed in revolutions per minute divided by 60. Application engineers from Woodward or any of its authorized distributors or agents are always available to assist you in selection of the correct control for your system, or to answer questions concerning control installation, operation, or calibration.
