丰满地震台水氡井引水装置的改进与性能评价

IMPROVEMENT AND PERFORMANCE ASSESSMENT OF WATER DIVERSION DEVICES IN WATER RADON WELL IN FENGMAN SEISMIC STATION

在日常的水氡取样环节中,除应取的主样和副样外,还需对水氡井进行定时引水,以保证所取水样更接近深部地下水天然动态。然而,在实际观测和操作中,由于人工引水时间因人而异,以及水泵的新旧与功率大小的不稳定,致使观测数据中带有一定误差。引水装置改进后,用自动控制装置对引水量进行定量控制,消除了一些随机影响,提高了观测数据精度和辅助测项—水位资料的可用性。

In order to ensure water samples closer to nature of deep groundwater, it needs to regularly pump in addition to primary and secondary samples taken in daily sampling of water radon. Some errors appeared in observed data due to difference of pumping time for different persons, as well as difference of pumps＇ performance or power. Improved water diversion devices with automatic control system may quantitatively control pumping capacity, eliminate some random effects and improve accuracy of observed data and usefulness of auxiliary material such as water level data.
