Abstract

The utility model discloses a non-blocking self-suction sewage pump which includes a flap door, a front cover, a liner, an impeller, a mechanical sealing ring, a bearing body and a pump body. The utility model is characterized in that the pump body is provided with a channel bin for water supply which is arranged at the front of the impeller; the chamber wall of the channel bin positive facing to the impeller is provided with the front cover; the impeller is a half-open dual-vane impeller, and well solves the blocking problem, and is convenient for the transmission of the large-grain suspended matters liquid medium.

Description

There is not the self-suction sewage pump of obstruction
Technical field
The utility model relates to a kind of nothing and stops up self-priming centrifugal sewage pump, is particularly useful for municipal wastewater and industrial waste water treatment system.
Background technique
At present, because its structure is original, there is following shortcoming in pollution discharge pump on the market: easy blocking blades, liner plate are difficult for changing, and are unfavorable for long-term use and daily maintenance.
Summary of the invention
The utility model provides a kind of nothing to stop up self-suction sewage pump.Be made up of flap valve, protecgulum, liner plate, impeller, mechanical seal, axle, bearing support, the pump housing, impeller is the semi-open type two blade impeller.
The inner at described axle is provided with the oil lubrication mechanical seal structure.Between described protecgulum and impeller, be provided with preposition water channel storehouse.
The utility model overcome traditional submerged sewage pump intrinsic shortcoming, it is low to have a cost, the characteristics of reliable performance, initiative rotor part design-adjustable makes its product that great raising all be arranged in applicability with on working life.It has unique oil lubrication mechanical seal structure, no blocking blades, and replaceable liner plate, the protective gear project organization that is easy to safeguard is more suitable for the processing of sewage.
The battleship formula form structure that it is unique belongs to exclusively initiative.This series pump has 50 to the 350 Ф plurality of specifications from bore Ф, flow 10～1200m at present 3/ h, lift 7～40m.
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Description of drawings
Diagrammatic sketch is a structural representation of the present utility model.
1. flap valves among the figure, 2. protecgulum, 3. liner plate, 4. impeller, 5. mechanical seal, 6. spool, 7. bearing support, the 8. pump housing.
Embodiment
Open protecgulum 2 sewage and enter the preposition water channel storehouse of impeller 4 fronts, impeller 4 is the semi-open type two blade impeller, can prevent to stop up, and is convenient to the conveying of large particle suspended matter liquid medium; Liner plate 3 can change, and unique oil lubrication mechanical seal structure is adopted in mechanical seal 5, has guaranteed the reliability of sealing; The pump housing 8 carries out blowdown to the top by flap valve 1 with the sewage self-priming.
The beneficial effects of the utility model are: unique oil lubrication mechanical seal structure, no blocking blades and replaceable liner plate have solved blockage problem, are more suitable for the transport process of sewage, have prolonged the working life of the pump housing.
