Abstract

The utility model discloses a hard alloy amphibious mine vertical pump capable of idling and serial connection. When water having a positive pressure greater than the barometric pressure always exists at the suction inlet of the mine vertical pump connected in series, an upper pump body at least comprises three draining tubes for the water pump leaked water led out from three isolated cavities. The first draining tube is communicated with the suction inlet of the pump, and the second draining tube and the third draining tube are opened for the outside. When water having a positive pressure greater than the barometric pressure exists at the suction inlet of the mine vertical pump connected in series, the water having a positive pressure is firstly delivered to the first cavity of the upper pump body by the first draining tube; a positive pressure equivalent to the pressure of the suction inlet is established in advance, so that a resistance is added for the leakage of an impeller chamber, and the leakage of the impeller chamber can be reduced. If the leakage of the impeller chamber is greater than that of a shaft hole of the first cavity, a part of the leakage can be recovered to the suction inlet via the first draining tube, which can reduce energy loss.
