Description

Submersible pump

Technical Field

The utility model relates to a submersible pump.

Background

The existing submersible pump usually pumps liquid from the side part of the pump body, and when the submersible pump is placed in a deep well and other elongated water containing cavities for use, the distance between the side part of the pump body and the well wall is small, so that the effect of pumping liquid is poor, and the use requirement cannot be met.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a immersible pump suitable for narrow and small water cavity that holds in lateral part space.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a submersible pump comprises a motor for driving an impeller to rotate, wherein a passage penetrating the length direction of a rotating shaft of the motor is arranged in the rotating shaft of the motor, and the passage is communicated with a liquid flow passage of the impeller.

Compared with the prior art, the utility model discloses there are following technological effect: the pump inlet of liquid is arranged at the bottom of the submersible pump, and even in the water containing cavity with narrow side space, the water source is still abundant and stable, so that the pump liquid efficiency and stability of the submersible pump can be effectively improved.

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.

A submersible pump comprises a motor 10 for driving an impeller 22 to rotate, a passage 12 penetrating through a rotating shaft 11 of the motor 10 in the length direction is arranged, and the passage 12 is communicated with a liquid flow passage of the impeller 22. In specific implementation, the water flow enters from the lower end of the rotating shaft 11 and penetrates through the passage 12 to enter the pump shell 21, namely, the pumping direction of the liquid is consistent with the length direction of the water containing chamber, so that the liquid is pumped from the bottom of the submersible pump, and the pumping efficiency and stability of the submersible pump can be greatly improved.

Specifically, the rotating shaft 11 includes a power section 111, a connecting section 112 and an output section 113, the power section 111 with the passage 12 therein is located inside the motor 10, a hole 114 for liquid to flow through is formed in the circumferential direction of the connecting section 112, the hole 114 communicates the passage 12 with the internal cavity of the pump casing 21, and the output section 113 and the impeller 22 rotate synchronously.

Preferably, the power section 111 has an outer diameter larger than that of the output section 113, and the connecting section 112 includes connecting arms 115 arranged at intervals, and a gap between two adjacent connecting arms 115 forms the hole 114. Specifically, as shown in fig. 1, the connecting arm 115 is spaced around the central axis of the rotating shaft 11, and one end of the connecting arm 115 is connected to the power section 111 and the other end thereof is connected to the output section 113 and rotates synchronously therewith.

Specifically, the power stage 111 has a hollow tubular shape, and the hollow portion of the hollow tubular shape constitutes the passage 12.

In the embodiment shown in fig. 1, one end of the pump casing 21 is fixedly connected with the end cover of the motor, and the other end is connected with the infusion pipeline to form a pump fluid passage, and in other embodiments, the pump casing 21 is connected with the rotating shaft 11 of the motor 10 to form a rotating fit. It should be noted that the pump housing 21 forms a sealing fit with the motor 10 to ensure reliable delivery of the pump fluid. Furthermore, the pipe body A of the liquid conveying pipeline is connected with the shell of the motor 10 and forms sealing fit, namely the upper end and the lower end of the submersible pump can be directly connected with the water conveying pipeline, and the mounting and using requirements of the submersible pump in a shaft with a narrow inner diameter are met.
