SL3 1型雨量传感器的构件改进和维护方法

根据近几年的自动气象站野外维护工作经验,对SL3-1型翻斗式雨量传感器的各类易发故障原因进行分类分析,依据相关技术要求和参考其他类似仪器的设计结构原理,并结合西藏气象台站各时段历年最大降水量的具体情况,对该仪器的进水构件、电气构件、底座构件提出了具体的改进措施和建议,达到减少该仪器的故障发生频次和提高观测精度的目的。为保证校准后的仪器符合准确性和比较性的要求,总结该仪器野外维护工作中时效方面存在的问题,提出自制存放核心部件专用设备箱的建议,以提高该仪器的野外维护工作时效。

Component Improvement and Maintenance Methods of SL3 1 Rain Sensors

According to the field experiences from the maintenance practice in an automatic weather station in recent years, various kinds of common faults for SL3 1 tilting rain sensors are classifieds, based on the relevant technical requirements and design principles of other similar instruments.Combined with the specific circumstances of the annual maximum precipitation in Tibet, the improvement measures and suggestions for the water intake, electrical, and base components are put forward, to reduce the equipment failure frequency and improve the accuracy of observation. In order to ensure the calibration of instruments according with the accuracy and comparative requirements, the problems encountered in the field maintenance of equipment are summarized, and a self made special equipment box for storing core components is introduced, to improve the efficiency of field maintenance.
