    • A system and process for detecting dynamic segregation in concrete rotated within a mixer drum, such as mounted on a delivery truck. A system processor is programmed to monitor an instantaneous and averaged rheology parameter (e.g., instantaneous and averaged slump values) and to deploy one or more protocols for detecting the occurrence of segregation. A first protocol comprises monitoring the averaged slump or other rheology value of concrete during and immediately after a jump in drum speed of at least plus or minus four rotations per minute and detecting when a change in the averaged slump value meets or exceeds a threshold limit pre-selected by the user or the system processor; and an optional second protocol comprises monitoring the instantaneous slump or other rheology value of the concrete when the mixer drum is rotating at a constant speed for at least three successive rotations.
    • 一种用于检测在混合器鼓内旋转的混凝土中的动态偏析的系统和方法,例如安装在输送车上。 系统处理器被编程为监视瞬时和平均的流变学参数(例如,瞬时和平均的坍落度值)并且部署用于检测偏析发生的一个或多个协议。 第一个方案包括监测在每分钟至少加上或者四次转速的滚筒速度期间和之后的混凝土的平均坍落度或其他流变学值,并且检测平均坍落度值的变化何时达到或超过阈值极限 由用户或系统处理器选择; 并且可选的第二方案包括当混合器鼓以恒定速度旋转至少三次连续旋转时监测混凝土的瞬时坍落度或其它流变学值。

    • It is an object of the present invention to prevent recurrence of an overload condition after occurrence of the overload condition, thereby improving operability and safety in a drilling device. A motor 12 for rotating a drill is connected to an AC power source 10 through a motor control unit 28, a current detector 30, and a power switch 36. A magnet 16 is also connected to the AC power source 10 through the power switch 36 and a full-wave rectifier 18. The motor control unit 28 rotationally drives the motor on the basis of a signal sent from a main control unit according to a state in which a motor start switch 38 is on. The main control unit 14 controls the motor control unit 28 to gradually reduce a supply voltage to the motor 12 when the motor 12 becomes overloaded, to gradually increase the voltage to the normal power supply condition when the overload condition is vanished, and to stop power supply to the motor 12 if the overload condition continues for a predetermined period.
    • 本发明的目的是防止在发生过载状态之后再次发生过载状况,从而提高了钻井装置的可操作性和安全性。 用于旋转钻机的电动机12通过电动机控制单元28,电流检测器30和电源开关36连接到AC电源10.磁体16还通过电源开关36连接到AC电源10 和全波整流器18.电动机控制单元28根据电动机启动开关38接通的状态,基于从主控制单元发送的信号旋转驱动电动机。 主控制单元14控制电动机控制单元28,当电动机12变得过载时,逐渐降低对电动机12的供电电压,当过载状况消失时,电压逐渐升高到正常供电状态,并停止供电 如果过载状态持续一段预定时间,则供给电动机12。
