Abstract

The invention discloses a submersible axial flow pump. The pump comprises an outer cylinder body and a cylinder cover, a water inlet is formed in the lower end of the outer cylinder body, a filter screen is arranged in the water inlet, a water outlet is formed in one side of the upper end of the outer cylinder body, a partition plate is arranged at the position, in the outer cylinder body, at theupper end of the water outlet, an inner cylinder body is arranged in the middle of the lower end of the partition plate, a pump shaft is rotatably arranged in the inner cylinder body through a bearingseat, the lower end of the pump shaft extends out of the inner cylinder body to be connected with an impeller, a first O-shaped sealing ring is arranged between the lower end of the inner cylinder body and the pump shaft, a driving motor is arranged at the upper end of the partition plate, a motor shaft of the driving motor is connected with the upper end of the pump shaft, a step is arranged atthe upper end of the outer cylinder body, the lower end of the cylinder body cover is clamped on the step, and a sealing ring is arranged between the outer cylinder body and the cylinder cover.

Description

Technical field[0001]The invention relates to a water pump, in particular to a submersible axial flow pump.Background technique[0002]The submersible axial flow pump is a kind of water pump, which is often used for submerged pumping operations. At this time, it is necessary to put forward higher sealing requirements for the submersible axial flow pump, especially the waterproof part of the driving motor. At present, the driving motor of the submersible axial flow pump is installed in the cylinder cover, and the cylinder cover is clamped on the cylinder body through the clamp and the sealing ring. When the clamp is clamped, it is easy to cause uneven force and cause the partial seal At the same time, in the cylinder body, the water flow will continue to cause continuous impact on the connection between the pump shaft and the motor shaft, the seal is relatively weak, and it is also a part that is extremely prone to water leakage. In summary, the above two parts are relatively easy Ther...
