Abstract
The utility model provides an explosion-proof diving and sand discharge electric pump for mine relating to the mechanical engineering pump field, which is mainly used for the operation of water supply and drainage for mine. The utility model is characterized in that: an impeller is a down drainage type; the shape of a water yielding guide vane is oblique expansion type; a pump body is double-layer type with circular bead. Because the impeller is a down drainage type, the particulate matters such as sand do not sedimentate or agglomerate with small resistance and completely balanced axial forces, and the mechanical seal is adopted with easy cooling process, thereby having reliable operation, high efficiency and long service life.
Description
Technical field
The utility model relates to the pump field in the mechanical engineering.Be mainly used in mine plumbing operation.
Technical background
Its structure of mine explosion-suppression Submerged Motor Pumps of using at present is up attraction type, and after stopping using, particulate matters such as the coal in the water, sand can deposit in impeller, lump, and make flow passage not smooth, cause and can't re-use.
Summary of the invention
For the shortcoming that the mine explosion-suppression Submerged Motor Pumps that overcomes present use exists particulate matters such as coal, sand to deposit in impeller, to lump, the utility model provides that a kind of impeller outlet place resistance is little, axial force can complete equilibrium and the easy flame-proof type submersible sand discharging electric pump of cooling of mechanical seal.
The realization the technical solution of the utility model is:
Wait the rotation of drive lower suction type impeller by explosion-proof submerged motor by axle, make its transformation of energy, thereby realize the water outlet stator in the pump housing and go out particulate matters such as bucket Jiang Shui and Sha raising out together.Because the pressure that impeller ring leaks out directly rushes at the mechanical seal box body, so Sealing cools off the axial force complete equilibrium easily.
The utility model has the advantages that: because impeller is lower suction type, so particulate matter such as sand can not deposit, lump, and guaranteed that resistance is little because of the structure characteristic at impeller outlet place; Axial force energy complete equilibrium; Mechanical seal is easily cooled off; Therefore, reliable, efficient is high, the life-span is long.
