Abstract
The utility model relates to the technical field of water pumps, in particular to a novel submersible sewage pump. The novel submersible sewage pump is characterized by comprising a motor cover, a motor shell, an oil cavity, a mechanical seal, a pump cover, a butt joint seal, an O-shaped seal, a shaft seal, an impeller, a pump seat, a pump shaft and a shaft sleeve. According to the novel submersible sewage pump, the shaft sleeve is arranged in the middle end of the pump shaft, and the shaft sleeve is used for stabilizing the pump shaft, guaranteeing safe operation of the pump shaft, reducing turbulence and impact produced at a medium overflowing portion, and improving efficiency and stability of the pump.
Description
Technical field
The utility model relates to the pump technology field, especially a kind of Novel submersible pollution discharge pump.
Background technique
Traditional proof submersible sand discharging pump is after start work, the pressure at chamber and oil sealing place can raise between pump cover and the pump housing, grease chamber's sealing needs often to change, otherwise pump shaft can produce breakage, equipment can't be turned round, and the pump housing crosses to fail to be convened for lack of a quorum and produces turbulent flow and impact, thereby increases the hydraulic loss of pump, makes the Efficiency Decreasing of pump.
Summary of the invention
For addressing the above problem, the utility model provides a kind of Novel submersible pollution discharge pump, described a kind of Novel submersible pollution discharge pump, it is characterized in that, comprise: motor cover 1, motor casing 2, grease chamber 3, mechanical seal 4, pump cover 5, Butt sealing 6, O type circle 7, shaft sealing 8, impeller 9, pump seat 10, pump shaft 11, axle sleeve 12, described a kind of Novel submersible pollution discharge pump, be provided with axle sleeve 12 in pump shaft 11 middle-ends, described axle sleeve 12 is to stablize pump shaft 11, guarantee pump shaft 11 safe operations, reduce turbulent flow and impact that the medium overcurrent partly produces, improved pump efficiency and stability.
The beneficial effects of the utility model are: guarantee the pump shaft safe operation 1..2. improve the efficient of pump.3. prolong the working life of pump.
Description of drawings
Fig. 1 is the utility model general structure schematic representation;
Wherein: motor cover 1, motor casing 2, grease chamber 3, mechanical seal 4, pump cover 5, Butt sealing 6, O type circle 7, shaft sealing 8, impeller 9, pump seat 10, pump shaft 11.
Embodiment
Described a kind of Novel submersible pollution discharge pump is provided with axle sleeve 12 in pump shaft 11 middle-ends, and described axle sleeve 12 is to stablize pump shaft 11, guarantees pump shaft 11 safe operations, reduces turbulent flow and impact that the medium overcurrent partly produces, has improved pump efficiency and stability.
