作为混凝土搅拌站重要构件的配料秤,是确保混凝土计量准确、配比合格的关键所在。下面笔者以2HDP-1200III型配料秤为例,分析配料秤使用过程中造成称量配料误差的原因:第一,配料秤静态称量误差。静态称量误差是配料秤秤体静止时的计量误差,它与传感器、称重显示控制器的计量性能和安装调试的质量密切相关,其误差直接影响配料误差。第二,落差。落差是在配料计量时,在配料控制器
As an important component of concrete batching plant batching scales, is to ensure accurate measurement of concrete, the ratio of qualified key. The following author to 2HDP-1200III-type batching scale, for example, the analysis of batching scale weighing process used in the cause of the error: First, batching scales static weighing error. The static weighing error is the metering error when the ingredient scale body is stationary, which is closely related to the metrological performance of the sensor and the weighing indicator controller and the quality of the installation and commissioning. The error directly affects the ingredient error. Second, the gap. Drop is measured in the ingredients, the ingredients in the controller
