5、，测速滚筒上的积料要经常清理；（2）定期对称重托辊进行润滑，每年至少两次，并且润滑后要重新调零；（3）始终保持皮带沿输送机的中心线运行，如果由于物料偏载造成皮带跑偏超差，必须调整加料机构，如果输送物料时皮带回归中心而空皮带运行跑偏，应在秤区以外设置防跑偏托辊；（4）秤架上要防止过载、冲击、严禁在秤架上站人，有条件时可加防护；（5）定期检查测速滚筒与皮带的接触情况，有打滑或沾料情况应及时处理。（6）17A/B型皮带秤的调平衡17A/B型皮带秤使用一段时间后，一般2～4个月应检查传感器输出平衡情3www.sanyuan-electric.com售后服务电话：+86-01330520

7、；用冷风机把仪表内部的灰尘吹掉；目视仪表的所有接线，插接件，集成电路的插接是否牢靠，用手按结实。仪表应尽可能选择远离强电场、强磁场和强脉冲源的地方，机房内最好有防尘措施，保证仪表的电子线路在清洁的空气环境中工作，防止积尘的静电干扰。四、防止雷击对皮带秤的损害雷击可能导致称重传感器和仪表内部多种器件的损坏。对于经常发生雷电的地区，尤其在雨季，更要注意皮带秤防护。主要方法有：（1）电源接地质量要好；4www.sanyuan-electric.com售后服务电话：+86-013305201772s
