MDR-SCD-10-Q 取料机断链保护装置

       MDR-SCD-10-Q 取料机断链保护装置是针对桥式刮板取料机 / 耙架式取料机等沿轨道做往复直线运动的设备而开发设计的。取料机正常工作时，其从动轴随主动轴一同往复旋转，从动轴保持某一转速，当断链、断带、打滑等故障发生时，其从动轴转速大辐下降甚至为零。断链保护装置监测从动轴转速，当从动轴转速于设定值（从动轴正常转速的80）时，断链保护器动作，输出一开关信号，用于控制驱动电机停止运行，从而保护设备，并发出声光警示，提示操作人员处理故障。
        The MDR-SCD-10-Q chain break protection device is developed and designed for equipment such as bridge-type scraper conveyors and scraper frame conveyors that move in a straight line along a track. When the conveyor is operating normally, its driven shaft rotates in tandem with the driving shaft, maintaining a certain rotational speed. When chain break, belt breakage, slipping, or other faults occur, the rotational speed of the driven shaft drops significantly or even becomes zero. The chain break protection device monitors the rotational speed of the driven shaft. When the rotational speed of the driven shaft reaches the set value (80% of the normal rotational speed of the driven shaft), the chain break protector activates, outputting a switch signal to control the driving motor to stop running, thereby protecting the equipment and issuing audible and visual warnings to alert the operator to handle the fault.

       德克西尔的SCD-10断链保护器主要由SCD-1速度传感器和保护器组成。SCD-1速度传感器为一电磁感应式脉冲信号发生器。SCD-1速度传感器安装于输送机从动轴 上，随从动轴一起旋转，将从动轴的旋转 速度信号变换成脉冲信号，脉冲信号的频率与从动轴的转速成正比。德克西尔SCD-1速度传感器是一脉冲频率检测器，安装于就地电控箱或集控室内。SCD-10断链保护器接收速度传感器的信号，并检测脉冲信号的频率，当脉冲信号频率低于设定值时，SCD-10断链保护器动作，输出一开关信号，用于控制驱动电机停止运行，从而保护设备。SCD-10断链保护器动作后会自锁，此时即使速度传感器有正常脉冲信号输入，保护器也处于报警保护状态，短按复位键，让保护器复位。

       The SCD-10 Chain Break Protector of Texel consists mainly of SCD-1 speed sensor and protector. The SCD-1 speed sensor is an electromagnetic induction pulse generator. The SCD-1 speed sensor is mounted on the follower shaft of the conveyor and rotates with the follower shaft. It transforms the rotation speed signal of the follower shaft into a pulse signal. The frequency of the pulse signal is proportional to the speed of the follower shaft. The Dexcill SCD-1 speed sensor is a pulse frequency detector, which is installed in an in-place electronic control box or centralized control room. The SCD-10 break-chain protector receives the signal from the speed sensor and detects the frequency of the pulse signal. When the frequency of the pulse signal is lower than the set value, the SCD-10 break-chain protector acts and outputs a switch signal to control the driving motor to stop running, thus protecting the device. The SCD-10 chain breaker will lock itself when it operates. At this time, even if the speed sensor has normal pulse input, the protector is in alarm protection state. Short press the reset key to reset the protector.
