我矿一采区1999年6月发生突发性溃水，矿井井下变电所及泵房被淹没，矿井被迫停产。为尽快排出积水，在六井斜井筒内安装1台710kw潜水泵，在七井斜井筒内安装2台250D6X6到卧式离心泵进行抽水。由于七井倾角达26°且排水中随水位下降需经常移动水泵，就装用了254的吸水胶管。1吸
I mine a mining area in June 1999 sudden burst of water, mine underground substations and pump houses were flooded, the mine was forced to stop production. In order to discharge the water as soon as possible, a 710kw submersible pump was installed in the inclined shaft of Liujing Well, and two 250D6X6 horizontal centrifugal pumps were installed in the inclined shaft of the well to pump water. As the well of the dip angle of 26 ° and drainage with the water level down to move the pump often need to install a 254 suction hose. 1 suction
