《中国特种设备安全》2008年第4期刊登了一篇《电梯平衡系数平衡差值测量法》的文章,应该肯定这是一种有别于以往传统电梯平衡系数测量方法的创新方法,减少了通过测量曳引电动机的输人电流、电压、速度或功率,并通过绘图来间接确定平衡系数的方法存在较大的系统综合累积误差。作者对其中机房内、井道内2种轿厢与对重平衡差值的测量过程、方法进行了详细的阐述,但对这2种方法中平衡差值的测量笔者存在一些异议。作者在这2种测量方法中只阐述了测量平衡差值的仪器(压力传感器或称量装置)安装在钢丝绳上的夹具与支撑件之间,对测量仪器的方向并没有
“China Special Equipment Safety” 2008 the fourth published an article “lift balance coefficient balance difference measurement method” article, it should be affirmed that this is a departure from the traditional method of measuring the balance of the elevator traditional methods of innovation, reducing the By measuring the input current, voltage, speed or power of the traction motor, and indirectly determining the balance coefficient by plotting, there is a large systematic cumulative error. The author elaborates the measurement process and method of the difference between the two kinds of cars and the counterweight in the engine room and hoistway. However, there are some objections to the author’s measurement of the balance difference between the two methods. In these two measurement methods, the author only describes that the instrument (pressure sensor or weighing device) for measuring the balance difference is installed between the clamp and the support on the wire rope, and the direction of the measuring instrument is not
