Problems solved by technology

[0002] After the traditional submersible sewage pump starts to work, the pressure in the cavity between the pump cover and the pump body and the oil seal will increase, and the seal of the oil chamber needs to be replaced frequently, otherwise it will be damaged, making the equipment unable to work, and the over flow of the pump body will cause Generate turbulence and impact, thereby increasing the hydraulic loss of the pump and reducing the efficiency of the pump

Embodiment Construction

[0005] specific implementation plan

[0006] Attached blades 11 are arranged above the impeller, and a sealing surface is formed between the impeller attached blades 11 and the pump cover, which reduces the pressure between the pump cover and the pump body, the cavity and the oil seal, and ensures reliable sealing of the oil chamber. At the same time, it reduces the turbulent flow and impact generated by the liquid in the flow part of the pump body, thereby reducing the hydraulic loss of the pump and improving the working efficiency and stability of the pump.

Abstract

The invention relates to the technical field of water pump, in particular to a novel efficient diving sewage pump, which comprises a motor cover 1, a motor shell 2, an oil chamber 3, a mechanical seal 4, a pump cover 5, an O-shaped ring 7, an impeller 9, a pump base 10 and an impeller attached vane 11. The attached vane 11 is arranged above the impeller and forms a sealing surface with the pump cover to reduce the pressure between the pump cover and the pump body and between the chamber and the oil seal, thereby ensuring the reliable seal of the oil chamber. Meanwhile, turbulence and impact generated at the over-current part of the pump body of liquid are reduced so as to reduce the hydraulic loss of the pump and improve the work efficiency and stability of the pump. The invention has the advantages of reducing the pressure between the pump cover and the pump body and between the chamber and the oil seal so as to ensure the reliable seal of the oil chamber, changing the performance of the pump and improving the efficiency of the pump and prolonging the service life and work stability of the pump.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a novel high-efficiency submersible sewage pump. technical background [0002] After the traditional submersible sewage pump starts to work, the pressure in the cavity between the pump cover and the pump body and the oil seal will increase, and the seal of the oil chamber needs to be replaced frequently, otherwise it will be damaged, making the equipment unable to work, and the over flow of the pump body will cause Generate turbulence and impact, thereby increasing the hydraulic loss of the pump and reducing the efficiency of the pump. Contents of the invention [0003] The invention is a new type of high-efficiency submersible sewage pump, which is characterized in that it includes: motor cover 1, motor casing 2, oil chamber 3, mechanical seal 4, pump cover 5, O-ring 7, impeller 9, pump seat 10, impeller Attach blade 11. Attached blades 11 are arranged above the impeller...
