Submersible sewage pump, the pump uses a half-open new impeller, the pump efficiency can be increased by 30%. Beautiful appearance, small size, light weight, large flow, over-current part of the suction structure, strong sewage capacity, not because of small solid Particles or fibrous inhalation, and will not be damaged prematurely by the inhalation of abrasive media. The overall structure of the pump is simple, easy loading and unloading and maintenance. It is absolutely safe and reliable in the working surface containing gas and coal dust, and the silencers with independent intellectual property rights in the exhaust port have greatly improved the conditions of underground construction condition.
Structural features: Pneumatic motor part: by the rotor, leaves, cylinder, shell, upper and lower cylinder head, roof and other components. The rotor has four uniform distribution of the radial groove, slot with the blade, the upper and lower cylinder head each have a blown eye, the air pump starts, the high pressure gas from the inflatable eye to open the leaves of the leaves, while a large number of High pressure gas from the main duct into the cylinder, pushing the blade, driving the rotor rotation work. In the bottom of the shell with a sealed cavity, cavity with a gas ring, the water separated, the use of gas and water pressure, so that the ring rose, enhance the sealing effect.
