摘要
制作抽液井密封装置,实现密闭式抽液。利用潜水泵电机的最大输送能力,应用连通器负压原理,尽可能使周围的溶浸液通过含矿含水层定向流向抽液井,增强地层溶液的渗透能力,在保证潜水泵设备正常运转情况下,提高单孔最大抽液量。经改进密封装置,人为提升抽液井静水位,基本实现抽液井内无气体全充液,延长潜水泵电机正常使用寿命。该密封装置在地层渗透性较差的砂岩性铀矿床开采中使用效果尤为明显。
To achieve closed drainage, production well pumping fluid sealing device was invented. By application of the maximum transmission capacity submersible pump motor, according to the principle of communicating vessels negative pressure, as much as possible around the leached solution through the ore-bearing aquifers flows directionally to drainage wells to compensate flexible free space. Infil- tration capacity of the stratum solution was enhanced. To ensure the normal operation of the submersi- ble pump equipment, the maximum single-hole pumping volume was raised. Through improvement of the application of the sealing device, drainage well static water level was artificially boosted, which is basically realized drainage wells no gas with completely water filling. Therefore, purpose of the nor- mal life of the submersible pump motor was extended. The application effect of sealing device is par- ticularly obvious for submersible pumps at poor permeability of sand stone uranium deposits.
