Description

Technical Field

[0001] The utility model belongs to the field of pumps and relates to a submersible pump, in particular to a high-efficiency energy-saving submersible pump. Background Art

[0002] Submersible pumps are important equipment for deep well water extraction. When in use, the entire unit submerges in the water to extract groundwater to the surface. It is suitable for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading and other fields.

[0003] Due to the popularity of submersible pumps in modern life, submersible pumps can be seen everywhere. During the use of existing submersible pumps, due to the excessive centrifugal pressure inside the pump body, the water in the submersible pump flows out at a higher speed. Since the water flow rate is high at this time, the impact force of the water flow is large, and it is very easy to cause the connection between the submersible pump and the pipe to collapse and lose, which seriously affects the use efficiency of the submersible pump and causes high losses. Summary of the invention

[0004] The purpose of the utility model is to provide a high-efficiency energy-saving submersible pump to solve the above problems in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an efficient and energy-saving submersible pump, comprising a pump body with a water inlet port and a water outlet port, characterized in that a water outlet section for connecting corresponding pipe fittings is provided at the water outlet port of the pump body, and a slow-flow plate for slowing down the flow velocity and impact strength of the water flow is provided in the water outlet section;

[0006] The slow flow plate is provided with a plurality of water holes for water flow, and the slow flow plate is located in the water outlet section and is an integrally formed structure;

[0007] The outlet joint is connected to the corresponding pipe fitting through internal and external threads, and an expansion ring is sleeved on the outlet joint to improve the connection sealing strength;

[0008] A connecting flange 7 for improving the connection strength is radially extended outward on the outer peripheral wall of the water outlet node, and the corresponding pipe is connected to the water outlet port through the cooperation of the fastening bolt structure.

[0009] In the above-mentioned high-efficiency energy-saving submersible pump, a plurality of the water holes are arranged in sequence and spaced apart and distributed on the slow flow plate, and the water outlet section is an integrally formed structure arranged at the water outlet port of the pump body.

[0010] In the above-mentioned high-efficiency energy-saving submersible pump, the expansion ring is located between the water outlet node and the corresponding pipe connection, and the expansion ring can be a water-stop ring that expands when it comes into contact with water.

[0011] In the above-mentioned high-efficiency energy-saving submersible pump, the cross section of the water outlet section is arranged in a T-shaped structure.

[0012] Compared with the existing technology, the high-efficiency and energy-saving submersible pump has a simple structural design. The water outlet section and the slow-flow plate structure can effectively solve the problem of excessive centrifugal pressure inside the pump body causing the water in the submersible pump to flow out at a higher speed and with a larger impact force of the water flow. It has a good slow-flow effect, making the submersible pump discharge water smoothly. At the same time, through the expansion ring and connecting flange structure setting, it can effectively improve its connection strength and sealing performance to prevent leakage caused by excessive centrifugal pressure.
