Abstract
The utility model relates to the technical field of water pumps, especially a novel high efficiency diving pollution discharge pump, characterized in comprising a motor cover, a motor casing, an oil chamber, a mechanical seal, a pump cover, an O type ring, impellers, a pump seat and an impeller barrier. The impeller barrier is equipped above the impellers, the impeller barrier together with the pump cover forms a seal surface, thus lowering the pressure between the pump cover and the oil chamber and ensuring the reliability of the seal of the oil chamber; meanwhile, turbulent flow and impact of medium produced during pump body over-current portion are reduced, thus minimizing the waterpower loss and improving the working efficiency and stability.
Description
Technical field
The utility model relates to the pump technology field, especially a kind of new and effective proof submersible sand discharging pump.
Background technique
Traditional proof submersible sand discharging pump is after start work, the pressure at chamber and oil sealing place can raise between the pump cover and the pump housing, grease chamber's sealing needs often to change, otherwise can produce breakage, equipment can't be worked, 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, and the efficient of pump is reduced.
Summary of the invention
For addressing the above problem, the utility model provides a kind of new and effective proof submersible sand discharging pump, described a kind of new and effective proof submersible sand discharging pump, it is characterized in that, comprise: motor cover 1, motor casing 2, grease chamber 3, mechanical seal 4, pump cover 5, O type circle 7, impeller 9, pump seat 10, impeller catch 11, described a kind of new and effective proof submersible sand discharging pump, above impeller 9, be provided with impeller catch 11, described impeller catch 11 is connected into sealing surface with pump cover 5, reduced the pressure between pump cover 5 and the grease chamber 3, guarantee the reliability of grease chamber's sealing, simultaneously, reduce turbulent flow and impact that medium partly produces at pump housing overcurrent, thereby reduce the hydraulic loss of pump, improved pump work efficient and stability.
The beneficial effects of the utility model are: 1. reduced pressure between pump cover and the grease chamber, guaranteed the reliability of grease chamber's sealing.2. change pump performance, improved the efficient of pump.3. prolong the working life and the working stability of pump.
Description of drawings
Fig. 1 is a kind of new and effective proof submersible sand discharging pump general structure schematic representation.
Embodiment
As shown in the figure, described a kind of new and effective proof submersible sand discharging pump, above impeller 9, be provided with impeller catch 11, described impeller catch 11 is connected into sealing surface with pump cover 5, reduce the pressure between pump cover and the grease chamber, guaranteed grease chamber's sealing, reduced turbulent flow and impact that liquid partly produces at pump housing overcurrent, thereby reduce the hydraulic loss of pump, improved pump work efficient and stability.
