Description

Technical Field

[0001] This utility model relates to the field of submersible pumps, and in particular to a high-lift submersible pump with a booster module. Background Technology

[0002] Submersible pumps, widely used in agricultural irrigation, urban water supply, industrial cooling circulation, sewage treatment, and mining drainage, primarily function to extract groundwater or other liquid media from a low level to a high level to meet various production and domestic needs. Submersible pumps typically consist of key components such as a motor, pump body, and impeller. The motor drives the impeller to rotate, generating centrifugal force to draw in the liquid media and pressurize it for discharge. Their greatest advantage is their ability to operate directly submerged in water, avoiding the hassle of ground installation and long-distance pipeline laying, thus greatly improving work efficiency and space utilization.

[0003] With the advancement of technology and the diversification of needs, the performance of submersible pumps is constantly improving, such as increasing flow rate, optimizing energy consumption ratio, and enhancing corrosion resistance. Especially in some special environments, such as deep-sea mining and irrigation under extreme weather conditions, higher requirements are placed on the performance of submersible pumps. However, traditional submersible pumps still have some limitations in design, such as insufficient head and difficult maintenance, which limit their application range and efficiency. Utility Model Content

[0004] To address the problem that traditional submersible pumps in the prior art are often limited by factors such as motor power and impeller structure in their design, resulting in limited head and difficulty in meeting the needs of some high-head application scenarios, this utility model provides a high-head submersible pump with a booster module.

[0006] A high-lift submersible pump with a booster module includes a pump body, the output end of which is connected to an impeller; the pump body is also connected to an impeller chamber for covering the impeller via flanges and bolts; a booster tank is fitted around the outside of the pump; the booster pipe is a cylindrical structure that tapers inward at both ends; the taper ends are respectively configured as a sealing interface and a water inlet interface; the sealing interface is sealed to the pump body via flanges and bolts; one end of the water inlet interface is connected to an external water pipe via flanges and bolts; the other end of the external water pipe is used to connect to the output end of a series pump;

[0007] Furthermore, the transition between the booster tank and the sealing interface and the water inlet interface is a rounded transition; the overall length of the booster tank is greater than the length of the pump body;

[0008] Furthermore, the outer wall of the booster tank is provided with a cable sealing port for connecting the external cable to the pump body; the cable sealing port is sealed to the external cable by a nut and a sealing ring.

[0009] Furthermore, several handles are welded to the outer wall of the pressurization tank;

[0010] Furthermore, sealing elements are provided at the connection points between the sealing interface and the pump body, and between the water inlet interface and the external water pipe, to seal the gaps generated by the connection between the flanges.

[0011] Furthermore, the seal includes two retaining rings connected by a pivot; the other ends of the two retaining rings are connected by bolts and nuts after they are engaged with each other.

[0012] Furthermore, the cross-section of the retaining ring is a "U" shaped structure; the groove of this structure is used to lock the flange connection between the sealing interface and the pump body, and between the water inlet interface and the external water pipe, and the inner side wall of the retaining ring is provided with a rubber sealing gasket.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] This invention introduces a booster module, namely a booster tank fitted outside the submersible pump, which obstructs the water flow and converts it into pressure, thereby significantly increasing the pump's head.

[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail below:

[0021] This utility model discloses a high-lift submersible pump with a booster module, such as... Figure 1-4 As shown, a high-lift submersible pump with a booster module includes a pump body 1, with an impeller 11 connected to the output end of the pump body 1; the pump body 1 is also connected to an impeller chamber 12 for covering the impeller 11 via flanges and bolts; a booster tank 2 is fitted around the outside of the pump; the booster tank 2 is a cylindrical structure with both ends tapering inwards; and the tapering ends are respectively configured as a sealing interface 21 and a water inlet interface 22; the sealing interface 21 is sealed to the pump body 1 via flanges and bolts; one end of an external water pipe 7 is connected to the water inlet interface 22 via flanges and bolts; the other end of the external water pipe 7 is used to connect to the output end of a series pump 8; the transition between the booster tank 2 and the sealing interface 21 and the water inlet interface 22 is a rounded corner. The overall length of the booster tank 2 is greater than that of the pump body 1. In this embodiment, the design principle of the booster tank 2 is to use its own structure and length to impede the water flow to a certain extent, thereby converting this impediment into the pressure required for the water flow. At the same time, the rounded transition design between the booster tank 2 and the sealing interface 21 and the water inlet interface 22 helps to reduce the energy loss of the water flow at the bend. The water flows out from the output end of the series pump 8 and first enters the water inlet interface 22 of the booster tank 2. Inside the booster tank 2, the water flow is impeded by the tank wall, the flow rate slows down, and the pressure increases. Subsequently, the water flow continues to flow to the input end of the pump body 1, thereby increasing the pressure of the water flow and thus increasing the head of the submersible pump.

[0022] like Figure 1-4 As shown, the outer wall of the booster tank 2 is provided with a cable sealing port 3 for connecting the external cable 5 to the pump body 1; the cable sealing port 3 is sealed to the external cable 5 by a nut and a sealing ring; in this embodiment, when installing the pump body 1, the external cable 5 is passed through the cable sealing port 3, and then the nut is tightened, so that the sealing ring is gradually compressed and tightly wrapped around the cable 5; during the operation of the pump body 1, the sealing ring continues to maintain a sealed state;

[0023] like Figure 1-3 As shown, several handles 4 are welded to the outer wall of the pressure tank 2. In this embodiment, the handles 4 are welded to the outer wall of the pressure tank 2 mainly based on ergonomic principles, so that operators can better hold the equipment when installing, disassembling or moving the submersible pump, thereby increasing the convenience and safety of operation. When it is necessary to install, disassemble or move the submersible pump, the operator can hold the handles 4 and apply force through the handles 4 to easily perform the corresponding operation on the submersible pump.

[0024] like Figure 1-3As shown, sealing elements 6 are provided at the connections between the sealing interface 21 and the pump body 1, and between the water inlet interface 22 and the external water pipe 7, to seal the gaps created by the flange connections. In this embodiment, the sealing element 6 is used to seal the gaps created by the flange connections. Its principle is to utilize the material properties and structural design of the sealing element 6 to fill the tiny gaps at the flange connections and prevent liquid leakage. When the submersible pump is working, the liquid inside the pump is under a certain pressure. If the flange connections are not sealed tightly, the liquid will leak, affecting the pump's working efficiency and performance.

[0025] like Figure 3 As shown, the sealing element 6 includes two retaining rings 61 connected by a rotating shaft; the other ends of the two retaining rings 61 are connected by bolts and nuts after they are interlocked; the cross-section of the retaining ring 61 is a "U" shaped structure; the groove of this structure is used to lock the flange connection between the sealing interface 21 and the pump body 1, and between the water inlet interface 22 and the external water pipe 7, and the inner side wall of the retaining ring 61 is provided with a rubber sealing gasket; in this embodiment, the two retaining rings 61 of the sealing element 6 are connected by a rotating shaft, and then the retaining rings 61 are locked at the flange connection between the sealing interface 21 and the pump body 1, and between the water inlet interface 22 and the external water pipe 7. Next, the other ends of the two retaining rings 61 are fastened together with bolts and nuts, so that the retaining rings 61 tightly hold the flange connection. During the operation of the submersible pump, the seal 6 continues to maintain a sealed state to prevent liquid from leaking from the flange gap. The "U"-shaped structure design of the retaining ring 61 is designed to better hold the flange connection. Its groove can fit tightly with the edge of the flange to provide a stable fixing effect. The rubber sealing gasket uses the elasticity and sealing properties of rubber to further enhance the sealing effect, fill the tiny gap between the retaining ring 61 and the flange, and prevent liquid leakage.

[0026] The implementation principle of this utility model embodiment is as follows:

[0027] After the water is output from the series pump 8, it enters the water inlet 22 of the booster tank 2 through the external water pipe 7. The flow velocity increases at the water inlet 22, and gradually decreases after entering the tank, while the pressure gradually increases. After the pressure is adjusted in the tank, the water enters the pump body 1. At this time, the pressure of the water has been increased, and it can be delivered with a higher head.

[0028] Through the special structural design of the booster tank 2, the resistance generated when the water flows in the tank is effectively converted into the required pressure, increasing the head of the water flow. This design enables the submersible pump to meet the delivery requirements of higher head without changing the structure and power of the pump body 1 itself, thus improving the application range and working performance of the submersible pump.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
