9905-794 操作控制器 控制装置 WOODWARD

【产品详情】

伍德沃德零件 9905-794 2301A 系列负载分配和速度控制。低压型号需要小于 10 mA 的最小燃料接触，可用于柴油发动机。

控制单元 2301A 系列 9905-794 是我们从伍德沃德的负载分配和控制系列提供的众多控制装置之一，这些控制装置来自我们当前的盈余或二手翻新库存。9905-794 装置是一种正向控制装置，作为低压型号运行在 10-40 Vdc 范围内，执行器电流为 0-20 mA。

当以最小燃料接触操作控制器时，找到执行器电流的位置并评估电流的运行情况，如果低于 20-160 mA，则最小燃料应小于 10mA，对于执行器电流在 40-320 mA 范围内的控制，最小燃料应小于 20 mA， 描述的最小燃料电流严格适用于诸如此类的前向作用控制模型。

此控件上的启动燃油限制电位器的目的是提供一种方法，用于在启动柴油品种的发动机时限制燃油架所在的位置。当启动燃料的电位计设置在最大执行器位置（即它应该处于的主要位置）时，一旦速度控制接管，限制位置就会自动断开。

如果在运行期间原动机未在额定空载速度下平衡，则控制可能不稳定，如果是这种情况，则评估控制器上的外部导线以确定它们是否已正确屏蔽，则控制器上的外部接线可能需要更多屏蔽。

【英文介绍】

Woodward Parts 9905-794 2301A Series Load distribution and speed control. Low-pressure models require a minimum fuel contact of less than 10 mA and can be used in diesel engines.

Control Unit 2301A Series 9905-794 is one of the many controls we offer from Woodward's Load Distribution and Control range, which come from our current surplus or used refurbished stock. The 9905-794 device is a forward control device that operates in the 10-40 Vdc range as a low-voltage model with an actuator current of 0-20 mA.

When operating the controller with the minimum fuel contact, find the position of the actuator current and evaluate the operation of the current, if below 20-160 mA, the minimum fuel should be less than 10mA, for the control of the actuator current in the range of 40-320 mA, the minimum fuel should be less than 20 mA, and the minimum fuel should be less than 20 mA. The minimum fuel current described is strictly applicable to such forward-acting control models.

The purpose of the starting fuel limit potentiometer on this control is to provide a method for limiting the location of the fuel stand when starting a diesel type engine. When the potentiometer for starting the fuel is set at the maximum actuator position (i.e. the main position it should be in), the limit position is automatically disconnected once the speed control takes over.

If the prime mover is not balanced at rated no-load speed during operation, the control may be unstable, if this is the case, the external wires on the controller are evaluated to determine if they have been properly shielded, and the external wires on the controller may require more shielding.
