遥控示速表是我们利用普通电压表经简单改装而成的一种间接测量纸机速度的仪表。装在我厂2~#造纸机上使用两个多月以来,证明其示速稳定,误差小于0.2米/分。纸机装上示速表后,便于人工调速,对于控制定量和稳定产量起了作用。这种示速表原理简单,制造方便,适用于整流子变速马达传动的纸机上测量车速,一般小厂均可自行制作。 作用原理:
Remote control speed meter is the use of ordinary voltage meter by a simple conversion made of an indirect measurement of paper machine speed meter. Installed in our plant 2 ~ # paper machine used more than two months, proved its speed and stability, the error is less than 0.2 m / min. Paper machine mounted on the speedometer, easy to manual speed control, for the control of quantitative and stable output played a role. This speedometer principle is simple, easy to manufacture, suitable for commutator variable speed motor drive on the paper machine to measure speed, the general small factory can make their own. Principle of action:
