Abstract

The invention discloses a high-sealing anti-blocking submersible axial flow pump. Through the structure, an inner connecting frame is fixedly connected with an outer cylinder and located in the outer cylinder, a shell is fixedly connected with the inner connecting frame and located in the inner connecting frame, and a bottom plate is fixedly connected with the shell; a rotating shaft penetrates through a first through hole to be movably connected with a motor, an impeller is fixedly connected with the rotating shaft, a first groove is formed below the through hole, a first sealing ring is in interference fit with the rotating shaft and located in the first groove, and a guiding cone is fixedly connected with the rotating shaft and located below the bottom plate; a second groove is formed in the bottom of the guiding cone, a second sealing ring is in interference fit with the rotating shaft and located in the second groove, water flow is guided by the guiding cone, meanwhile, water is isolated outside the bottom plate through three times of protection, and it is guaranteed that the motor does not make contact with the water.

Description

technical field [0001] The invention relates to the technical field of submersible electric pumps, in particular to a high-seal anti-clogging submersible axial flow pump. Background technique [0002] The submersible axial flow pump is a pump that relies on the force generated by the blades of the rotating impeller on the liquid to transport the liquid along the axis and submerge it into the water. It is mainly composed of a dry motor, hydraulic components and two or three mechanical seals. Currently , 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 a clamp and a sealing ring. When the clamp is clamped, it is easy to cause uneven force, resulting in local leakage of the sealing ring. leak. Contents of the invention [0003] The purpose of the present invention is to provide a high-seal anti-clogging submersible axial flow pump, which aims to solve the problem that the d...
