摘要
根据给煤机称重原理,分析给煤机三大主要计量误差原因:外部因素、机械因素和测量因素,并逐条给出解决方案,为给煤机定度准确性提供了保障。对比三种常见的校验方法后发现挂码校验法不仅节约大量人力、物力,而且计量准确性高,值得使用同类型给煤机的其他电厂借鉴。
According to the weighing principle of coal feeder,three causes leading to the error of coal feeder were analyzed,such as external factor,mechanical factor and measurement factor,for which detailed solutions were given to provide a guarantee for the calibration accuracy of coal feeder.By comparing the three common calibration methods,the method of hanging weight not only saves a lot of manpower and material resources,but also has high measuring accuracy,thus is worthy of being popularized and applied for other power plants using same type of coal feeders.
