Description

Technical Field

[0001] The utility model relates to the technical field of pipeline pumps, in particular to a low-noise pipeline pump. Background Art

[0002] In the field of fluid transportation, traditional pipeline pumps typically consist of a simple straight-through pump body structure, relying on a conveying propeller to propel the fluid in a single direction along the pipeline. While traditional pipeline pumps can provide a certain degree of efficiency when transporting fluid in the forward direction, they lack effective fluid control mechanisms when faced with reverse flow or fluid fluctuations, which can easily generate irregular vortices and affect fluid stability. Furthermore, the simple structure of traditional pipeline pumps results in high frictional resistance during fluid transportation, resulting in low efficiency and high noise levels during fluid flow, which can affect the pump's effectiveness.

[0003] In traditional technical solutions, commonly used structural designs make it difficult to ensure the unidirectional stable flow of fluid while effectively controlling noise. Existing pump bodies usually lack flow channel cavities and guide structures, which result in the inability of the fluid to form effective resistance when flowing in the reverse direction, generating eddy current interference, further weakening the pump's quiet effect and delivery stability. In addition, in traditional solutions, the friction resistance of the fluid in the flow channel is large, and the flow is not smooth enough, which affects the delivery efficiency. In particular, when conveying corrosive fluids, durability is difficult to guarantee. In view of this, research and improvement are carried out on the existing problems, and a low-noise pipeline pump is provided to solve the current problems. The purpose is to achieve the purpose of solving problems and improving practical value through this technology. Utility Model Content

[0004] The utility model aims to solve the technical problems existing in the prior art or related technologies.

[0005] The utility model discloses a low-noise pipeline pump, which specifically includes: a pipeline body, a motor and a delivery propeller, and the surface of the pipeline body is provided with a plurality of pump tubes arranged one-to-one corresponding to the delivery propellers, the inner side of the pipeline body is fixedly installed with a positioning flap, the surface of the positioning flap is provided with a first guide ring and a second guide ring, and the first guide ring and the second guide ring are located on the inner side of each pump tube, the motor is fixed to the inner side of the pipeline body through the pump tube, the output end of the motor is provided with a main shaft, the delivery propeller is fixedly installed on the surface of the main shaft, and the inner side of the pipeline body and the pump tube is provided with a flow channel cavity. Through this structural design, the fluid inside the flow channel cavity can form a stable unidirectional flow under the guidance of the positioning flap, the first guide ring and the second guide ring, effectively avoiding the generation of irregular vortexes when the fluid flows in the reverse direction, and ensuring a stable fluid delivery effect.

[0006] In a preferred example, the present invention can be further configured as follows: the flow channel cavity includes a main channel formed along the surface contour line of the conveying impeller and a plurality of curved branch structures connected in sequence along the inner wall of the pump tube and along the surface contour lines of the first guide ring and the second guide ring, and the connection angle of each curved branch structure with the main channel is set to prevent the reverse flow of the fluid; when the fluid flows in the forward direction, the fluid forms a relatively smooth flow path in the flow channel cavity, and when the fluid flows in the reverse direction, the fluid is subject to the eddy resistance inside the curved branch structure, thereby significantly reducing the reverse flow of the fluid. By providing multiple curved branch structures in the flow channel cavity, the flow path is smoother when the fluid flows in the forward direction, and the eddy resistance effectively reduces the backflow when the fluid flows in the reverse direction, thereby improving the one-way flow control effect of the fluid.

[0007] In a preferred embodiment, the present invention can be further configured as follows: the curved branch structure includes a plurality of branch channels with gradually increasing deflection angles, with guide walls provided within the branch channels for generating vortices to increase resistance during reverse fluid flow. The inlet and outlet of the flow channel cavity are respectively the fluid inlet and the fluid outlet, and the interior of the channel between the fluid inlet and the fluid outlet is formed by the plurality of curved branch structures into a continuous structure, which is used to increase the resistance of the fluid path during reverse flow and prevent the passage of reverse fluid. The plurality of branch channels with increasing deflection angles creates greater resistance to reverse fluid flow, effectively suppressing reverse flow and achieving unidirectional flow control of the fluid.

[0008] In a preferred embodiment, the present invention can be further configured such that the fluid inlet and outlet are each provided with a diffuser and a diverter cone fixed to the surface of the positioning flap. The diffuser and diverter cones are sleeved onto the surface of the main shaft, and the motor is fixedly mounted at the bottom end of the diverter cone. The provision of diffuser and diverter cones at the fluid inlet and outlet ensures fluid guidance, further reduces noise interference caused by turbulent flow, and improves the quietness of the pipeline pump.

[0009] In a preferred embodiment, the present invention can be further configured such that the flow channel cavity utilizes a symmetrically arranged curved branch structure, with each curved branch structure forming an angle of 30 to 70 degrees with the main channel to optimize the unidirectional flow of the fluid. This symmetrically arranged curved branch structure optimizes the unidirectional flow path of the fluid, creating greater resistance to reverse flow, thereby ensuring the stability and flow efficiency of the pipeline pump.

[0010] In a preferred example, the present invention can be further configured as follows: the positioning flap, the first guide ring, the second guide ring, the expansion cone and the guide cone are made of corrosion-resistant materials to be suitable for unidirectional flow control of corrosive fluids.

[0011] By adopting the positioning flap, the first guide ring, the second guide ring, the expansion cone and the drainage cone made of corrosion-resistant materials, the durability of the pipeline pump when conveying corrosive fluids is improved and its application range is broadened.

[0012] In a preferred embodiment, the present invention can be further configured such that the delivery propeller has a conical structure and is provided with a plurality of spiral blades on its surface. The bottom ends of the spiral blades are fixedly connected to a flow ring. The conical delivery propeller and the spiral blades on its surface design ensure smoother flow of fluid within the pump body, effectively reducing frictional resistance and improving delivery efficiency.

[0013] In a preferred embodiment, the present invention can be further configured such that the flow path inside the pipe body is directed from the expansion cone to the guide cone. By setting the direction of the fluid path, the fluid always flows in the set direction, thereby enhancing the fluid guidance and ensuring the stability of the fluid flow.

[0014] The beneficial effects achieved by the utility model are:

[0015] 1. In the utility model, by arranging a flow channel cavity and a curved branch structure inside the pipeline body, under the guidance of the first guide ring and the second guide ring, the fluid can be guided smoothly into the main channel when the fluid flows in the forward direction, and vortexes can be generated through the curved branch structure when the fluid flows in the reverse direction, forming the effect of a Tesla valve, effectively preventing and avoiding the interference of fluid vortexes on the pipeline pump, thereby ensuring the stability of the pipeline pump in various flow directions and improving the quietness of the pipeline pump.

[0016] 2. In the present invention, by arranging spiral blades and straightening rings on the surface of the conveying impeller, the flow path of the fluid is optimized, so that the fluid flows more smoothly in the pipeline, further reducing the fluid friction resistance and improving the fluid conveying efficiency.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0025] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0026] The following is combined with Figure 1-Figure 5 Some embodiments of the present invention provide a low-noise pipeline pump.

[0027] The present invention discloses a low-noise pipeline pump, comprising: a pipeline body 100, a motor 200, and a delivery propeller 300. In this embodiment, the surface of the pipeline body 100 is provided with a plurality of pump tubes 110 arranged one-to-one with the delivery propellers 300. A positioning flap 120 is fixedly mounted on the inner side of the pipeline body 100. The surface of the positioning flap 120 is provided with a first guide ring 130 and a second guide ring 140, and the first guide ring 130 and the second guide ring 140 are located on the inner side of each pump tube 110. The motor 200 is fixed to the inner side of the pipeline body 100 through the pump tube 110. The output end of the motor 200 is provided with a main shaft 210. The delivery propeller 300 is fixedly mounted on the surface of the main shaft 210. The inner sides of the pipeline body 100 and the pump tube 110 are provided with a flow channel cavity 111. This structure enables the fluid inside the flow channel cavity 111 to form a one-way flow under the guidance of the positioning flap 120, the first guide ring 130 and the second guide ring 140, avoiding eddy current interference when the fluid flows in the reverse direction, and ensuring stable delivery of the fluid.

[0028] In this embodiment, the flow channel cavity 111 includes a main channel formed along the surface contour line of the conveying impeller 300 and a plurality of curved branch structures connected in sequence. The curved branch structures are formed along the inner wall of the pump barrel 110 and the surface contour lines of the first guide ring 130 and the second guide ring 140. The connection angle between each curved branch structure and the main channel is set to prevent the reverse flow of the fluid. When the fluid flows in the forward direction, the fluid can pass through the main channel smoothly, while when it flows in the reverse direction, the fluid is subjected to the vortex resistance of the curved branch structure, which greatly reduces the reverse flow rate. This structure achieves the control effect of the unidirectional flow of the fluid and effectively reduces the possibility of the fluid flowing in the reverse direction.

[0029] In another embodiment, the utility model further optimizes the structure of the flow channel cavity 111 so that it can adapt to a more complex fluid delivery environment. In the flow channel cavity 111, the curved branch structure includes a number of branch channels with gradually increasing deflection angles, and a guide wall is provided in each branch channel. When the fluid flows in the forward direction, the fluid forms a smooth flow path in the main channel, and when flowing in the reverse direction, the guide wall inside the branch channel will generate vortices, thereby increasing the resistance and further suppressing the reverse flow. The inlet and outlet of the flow channel cavity 111 are respectively the fluid inlet and the fluid outlet, and the curved branch structures inside the channel are arranged continuously to ensure that the resistance of the fluid path is increased during reverse flow to prevent the reverse fluid from passing through.

[0030] In addition, this embodiment includes a diffuser cone 150 and a diversion cone 160 fixed to the surface of the positioning flap 120, respectively, on the inner sides of the fluid inlet and outlet. The diffuser cone 150 and the diversion cone 160 are sleeved onto the surface of the main shaft 210, and the motor 200 is fixedly mounted at the bottom end of the diversion cone 160. This arrangement guides the fluid in and out smoothly and effectively reduces noise interference caused by eddy currents, further improving the quietness of the pipeline pump.

[0031] Furthermore, the present invention can also be configured such that the flow channel cavity 111 employs a symmetrically arranged curved branch structure, with the angle between the curved branch structure and the main channel being 30 to 70 degrees. This angle range optimizes the unidirectional flow of the fluid, while providing greater resistance to reverse flow, thereby ensuring the stability and flow efficiency of the pipeline pump.

[0032] In addition, the positioning flap 120, the first guide ring 130, the second guide ring 140, the expansion cone 150, and the guide cone 160 can be made of corrosion-resistant materials to be suitable for unidirectional flow control of corrosive fluids. By using corrosion-resistant materials, the durability of the pipeline pump when conveying corrosive fluids is improved, and its application range is broadened.

[0033] In a further optimization of this embodiment, the delivery propeller 300 is designed as a conical structure, with several spiral blades 310 on its surface. The bottom end of the spiral blades 310 is fixedly connected to a straightening ring 311. The design of the conical delivery propeller 300 and the surface spiral blades 310 makes the fluid flow more smoothly within the pump body, effectively reducing the frictional resistance of the fluid and improving the delivery efficiency. In addition, the flow path within the pipeline body 100 is along the direction from the expansion cone 150 to the diversion cone 160. By setting the direction of the fluid path, it is further ensured that the fluid always flows in the set direction, thereby enhancing the fluid's guidance and flow stability.

[0034] The working principle and use process of this utility model:

[0035] Install the pipeline pump of the present invention in the desired fluid delivery system, ensuring that the interface between the pipeline body 100 and the external pipeline is well sealed. Check the fixing of the motor 200 to ensure that it is tightly installed with the pump tube 110, and ensure that the delivery propeller 300 is properly installed on the output end surface of the main shaft 210.

[0036] The motor 200 is started to drive the main shaft 210, which in turn rotates the delivery propeller 300, initiating fluid delivery. When fluid enters the inlet of the pipeline pump, it is guided into the flow channel 111 and, guided by the positioning flap 120, the first guide ring 130, and the second guide ring 140, into the main channel, forming a stable unidirectional flow path.

[0037] When the fluid flows in the forward direction, it passes through the main channel of the flow channel cavity 111 and is guided by the spiral blades 310 on the delivery propeller 300. The fluid flows smoothly along the spiral blades toward the outlet, where the rotation of the delivery propeller 300 actively transports the fluid. During this process, the flow-guiding structure reduces frictional resistance, ensuring smoother fluid flow and preventing unnecessary noise.

[0038] If reverse flow occurs in the system, the fluid will attempt to reverse through the flow channel cavity 111 and will be subject to the vortex resistance of the curved branch structure. The vortex formed by each branch structure during reverse flow will significantly increase the fluid resistance, inhibiting reverse flow, thereby ensuring unidirectional flow and stable operation of the device.

[0039] During use, the expansion cone 150 and the guide cone 160 further guide the fluid, avoiding noise caused by fluid turbulence while ensuring flow stability at the inlet and outlet. The use of corrosion-resistant materials extends the life of the equipment, making it suitable for conveying a variety of corrosive fluids.
