9905-147 机械调节机构 WOODWARD

【产品详情】

伍德沃德部分 9905-147 系列 2301A 负载分配和速度控制。反向作用控制，提供低压或高压型号，并安装在金属板框架中。

伍德沃德 9905A 系列的负载分配和速度控制 147-2301 可在 AX Control Inc. 购买。我们购买、出售、维修和翻新控制器。该控制是反向操作模型，该型号的执行器电流读数为 0-200 mA，需要 88-131 V 交流或 90-150 Vdc 电源。 操作时，将其连接到所用系统所需的控制接线端子位于控制器的前面板下方。该控件由金属板组成，由 <> 个端子组成，用于将控件连接到原动机。

通常与反向作用控制一起使用的执行器配备了机械调节机构，调速器上的速度设置略高于 9905-147 控制单元上使用的速度设置。

在运行过程中，如果原动机有轻微的不稳定，请开始稍微调整执行器补偿电位器，并继续调整电位器，直到达到原动机的稳定性。 如果执行器异常活跃，则可以说相反。在开始降低电位计之前评估不稳定性。

重要的是要注意，当蒸汽架处于最小位置时，在任何情况下都不应将执行器水平降至最低。如果执行器在关闭蒸汽架之前到达最小位置，则控制器无法关闭涡轮机，并且会对设备造成损坏。

【英文介绍】

Woodward Part 9905-147 Series 2301A Load distribution and speed control. Reverse action control is available in low or high pressure models and is mounted in a sheet metal frame.

Load distribution and speed Control for the Woodward 9905A series 147-2301 is available at AX Control Inc. Buy. We buy, sell, repair and refurbish controllers. The control is a reverse operation model and the actuator current reading for this model is 0-200 mA and requires 88-131 V AC or 90-150 Vdc power supply. When operating, the control terminals required to connect it to the system used are located below the front panel of the controller. The control consists of a metal plate consisting of <> terminals for connecting the control to the prime mover.

The actuators commonly used with the reverse action control are equipped with a mechanical regulation mechanism, and the speed setting on the governor is slightly higher than the speed setting used on the 9905-147 control unit.

During operation, if the prime mover is slightly unstable, start adjusting the actuator slightly to compensate the potentiometer, and continue adjusting the potentiometer until the stability of the prime mover is reached. If the actuator is abnormally active, the opposite can be said. Assess instability before starting to lower the potentiometer.

It is important to note that the actuator level should not be reduced to the minimum under any circumstances when the steam rack is in the minimum position. If the actuator reaches the minimum position before turning off the steam rack, the controller cannot turn off the turbine and damage to the equipment can be caused.
