| description | The utility model relates to a coal-bed gas well drainage and mining device which comprises a filter screen assembly, a cleaning assembly, a suction assembly and a back flushing assembly. The filter screen assembly is installed at the end of the suction pipeline assembly, the cleaning assembly is installed in the suction pipeline assembly, the cleaning end of the cleaning assembly extends into the filter screen assembly, the other end of the suction pipeline assembly is connected with the suction assembly, and the suction pipeline assembly is further communicated with a backflushing assembly. The filter screen is automatically cleaned in the pumping process of the water pump, and the use efficiency of the gas well drainage and mining water pump is improved.
本实用新型涉及一种煤层气井排采装置，包括过滤筛网组件、清洁组件、抽吸组件和反冲组件；所述过滤筛网组件安装在抽吸管道组件端部，所述抽吸管道组件内安装有所述清洁组件且所述清洁组件清洁端延伸至所述过滤筛网组件内，所述抽吸管道组件另一端连接有所述抽吸组件，所述抽吸管道组件还连通有反冲组件。本实用新型水泵抽吸过程中自动清洁过滤网，提高气井排采水泵使用效率。 |
