Description

Technical Field

[0001] The invention belongs to the technical field of full-flow submersible pumps, and in particular relates to a high-efficiency and energy-saving full-flow submersible pump with a built-in curved flow guide structure. Background Art

[0002] Full-flow submersible pumps are widely used in agricultural irrigation, urban water supply, industrial circulating water systems, etc. Traditional full-flow submersible pumps have problems such as low efficiency, high energy consumption, and high noise.

[0003] In the prior art, the performance of the pump is usually improved by optimizing the impeller design or improving the motor efficiency. However, these methods are difficult to fundamentally solve the problems of uneven fluid flow and large eddy current losses in the flow channel, resulting in limited improvement in the efficiency of the pump.

[0004] However, most of the traditional full-flow submersible pumps work in one direction, which makes the pump body work inefficiently and cannot be used flexibly. Summary of the invention

[0005] The purpose of the present invention is to provide a high-efficiency and energy-saving full-flow submersible pump with a built-in curved flow guide structure in order to solve the above-mentioned working efficiency problem of the full-flow submersible pump.

[0006] The technical solution adopted by the present invention is as follows: a high-efficiency and energy-saving full-flow submersible pump with a built-in curved guide structure, comprising a submersible pump main body shell, a left pump body port and a right pump body port are arranged at both ends of the submersible pump main body shell, and sealed submersible motors are arranged inside the left pump body port and the right pump body port, a rotor assembly is arranged at the output end of the sealed submersible motor, and impeller one and impeller two are arranged on the surface of the rotor assembly inside the left pump body port and the right pump body port, respectively.

[0007] By adopting the above technical scheme, a left pump body port and a right pump body port are set at both ends of the submersible pump main body shell. Starting the internal sealed submersible motor and cooperating with the rotor assembly, impeller one and impeller two can make the device adjust the working direction as needed to form a bidirectional full-flow submersible pump. By setting up a bidirectional full-flow submersible pump, less electric energy can be occupied while achieving the same flow rate, and bidirectional drainage can be performed when needed. It has greater flexibility and is suitable for occasions that require frequent switching of flow direction. Through the built-in curved guide structure, the flow path of the fluid in the flow channel is optimized, the friction loss and eddy loss between the fluid and the inner wall of the flow channel are reduced, the fluid flow is smoother, the efficiency of the pump is significantly improved, and the energy consumption is reduced.

[0008] In a preferred embodiment, the surfaces of the rotor assembly inside the left pump body port and the right pump body port are provided with rotor shells, and the surface of the rotor shell inside the left pump body port is provided with impeller 1.

[0009] By adopting the above technical solution, the provided rotor casing can protect the rotor assembly, and at the same time, the impeller 1 can rotate together with the rotating assembly to carry out subsequent work.

[0010] In a preferred embodiment, impeller 2 is provided on the surface of the rotor shell inside the right pump body port.

[0011] By adopting the above technical solution, the rotor housing and the second impeller are arranged inside the right pump body port, which can protect other structures and facilitate the operation of the device.

[0012] In a preferred embodiment, a slide rail is provided on the inner surface of the left pump body port corresponding to the impeller 1, and a slide rail is provided on the inner surface of the right pump body port corresponding to the impeller 2.

[0013] By adopting the above technical solution, when the fluid passes through the flow channel, impeller one and impeller two can guide the fluid to flow smoothly along their curved surfaces, cooperate with the slide rail to reduce the friction loss between the fluid and the inner wall, and avoid the generation of vortexes, thereby improving the efficiency of the pump.

[0014] In a preferred embodiment, the impeller 1 and the impeller 2 are arc-shaped, and the radius of curvature thereof matches the inner diameter of the flow channel.

[0015] By adopting the above technical solution, the structure can be rotated better by setting the impeller 1 and the impeller 2 into an arc shape and matching the radius of curvature with the inner diameter of the flow channel.

[0016] In a preferred embodiment, the number of impeller 1 and impeller 2 is set to 6, and the inclination angle of impeller 1 and impeller 2 is 30°.

[0017] By adopting the above technical solution, impeller one and impeller two are set to 30 degrees and 6 blades, which greatly improves work efficiency and reduces equipment costs.

[0018] In a preferred embodiment, the sealed submersible motors inside the left pump body port and the right pump body port are respectively installed inside the submersible pump main body shell through a mounting frame and a fixing frame.

[0019] By adopting the above technical solution, the sealed submersible motors inside the left pump body port and the right pump body port can be fixed by cooperating with the mounting frame and the fixing frame, so that the device can work stably.

[0020] In a preferred embodiment, the submersible pump main body shell and the left pump body port, the submersible pump main body shell and the right pump body port are connected through flange one and flange two, and the surfaces of flange one and flange two are threadedly connected with multiple threaded bolts, and one end surface of the threaded bolts is threadedly connected with a nut.

[0021] By adopting the above technical scheme, the left pump body port and the right pump body port can be correspondingly installed on the two ends of the submersible pump main body shell through flange one and flange two, and can also be individually installed or disassembled according to usage needs. The co-arranged threaded bolts and nuts can fix the left pump body port and the right pump body port on the two ends of the submersible pump main body shell, so that the device can work stably, and it is also convenient for the staff to replace and repair individually or as a whole.

[0022] In a preferred embodiment, a mounting plate is welded to the top surface of the submersible pump main body shell, and a second power line and a first power line are arranged on the surface of the mounting plate.

[0023] By adopting the above technical solution, the mounting plate arranged on the top of the submersible pump main body shell facilitates the installation of power line 2 and power line 1. At the same time, power line 2 and power line 1 can be connected to an external power supply to provide power for the equipment.

[0024] In a preferred embodiment, four support frames are welded to the bottom end of the outer surface of the submersible pump main body shell, and a fixed base is welded to the bottom end of the four support frames.

[0025] By adopting the above technical solution, welding four support frames on the surface of the submersible pump main body shell and welding a fixed base at the bottom end of the support frame can provide a stable supporting force for the equipment and also facilitate the placement of the device.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

The machine 19 cooperates with the rotor assembly 13, the impeller 12 and the impeller 2 14 so that the device can adjust the working direction as needed to form a bidirectional full-flow submersible pump. By setting up a bidirectional full-flow submersible pump, less electric energy can be consumed while achieving the same flow rate, and bidirectional drainage can be performed when needed.
