Description

Technical Field

[0001] The utility model relates to the technical field of circulating water pump accessories, in particular to a high-efficiency circulating water pump fluid energy-saving pressurizing device. Background Art

[0002] As a type of fluid conveying equipment, circulating water pumps are widely used in industries, construction, agriculture, etc. In the closed loop of heating systems or air-conditioning water systems, circulating water pumps do not lift water to a high place, but circulate water repeatedly in the system to overcome the resistance loss of the loop. It has no direct relationship with the height of the building, so it is called a circulating water pump.

[0003] The patent with announcement number CN203441836U proposes a fluid energy-saving supercharging device, which includes: a first supercharging chamber, and a supercharging device sleeved outside the first supercharging chamber; the supercharging device is a cavity structure, and an inclined baffle is arranged in the cavity structure, and the inclined baffle divides the cavity structure into a second supercharging chamber and a third supercharging chamber, and the inclined baffle is provided with a hole connecting the second supercharging chamber and the third supercharging chamber; a supercharging inlet connecting the first supercharging chamber and the second supercharging chamber is arranged on the side wall of the first supercharging chamber; a supercharging outlet is arranged on the side wall of the third supercharging chamber. It can achieve the effect of energy-saving supercharging under the condition of unchanged cross section. At the same time, the supercharging device provided by the present application has a simple structure, which not only saves the use of materials, but also reduces the manufacturing cost, and has a longer service life than similar supercharging devices, and can effectively overcome the resistance in the circulation system; it is installed at the outlet of the pump, which can significantly improve the head and flow of the fluid.

[0004] In the above case, when in use, the fluid is pressurized only by setting up a boosting chamber. This boosting method is highly dependent on the initial flow rate of the water flow. When the initial flow rate of the system is low, the boosting effect will be greatly reduced, thereby affecting the operating efficiency of the entire circulation system. In order to make up for the lack of boosting efficiency, it may be necessary to increase the operating power of the circulating water pump or extend the operating time to maintain the fluid flow rate and boosting effect required by the system. This will directly lead to an increase in system energy consumption, which is not in line with the modern design concept of energy saving and consumption reduction. Therefore, the utility model provides a high-efficiency circulating water pump fluid energy-saving boosting device to meet the needs. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A high-efficiency circulating water pump fluid energy-saving pressurization device, comprising a device pipe body, both ends of the device pipe body are fixedly connected with connecting flanges; a pressurization assembly, the pressurization assembly is used for energy-saving pressurization of the fluid, the pressurization assembly is connected with the device pipe body, the pressurization assembly includes a diversion cavity opened in the inner wall of the device pipe body, an inner pipe is arranged between the diversion cavity and the flow cavity of the device pipe body, an inclined diversion plate is fixedly connected to the inner wall of the inner pipe, and a plurality of flow holes are arranged in an annular and equidistant distribution on the inner wall of the inner pipe.

[0007] Optionally, the flow holes communicate the diversion cavity with the flow cavity, the flow holes are located on one side of the diversion plate, and the diversion plate is inclined towards the flow holes.

[0008] Optionally, spiral distribution of drainage grooves is arranged on the inner wall of the diversion plate.

[0009] Optionally, one end of the inner pipe is fixedly connected to one side of the inner wall of the device pipe body, an installation cavity is opened between the other side of the inner pipe and the inner wall of the device pipe body, a cross installation frame is fixedly connected to the inner wall of the installation cavity, and a turbine fan blade is rotatably connected inside the cross installation frame.

[0010] Optionally, the edge of the turbine fan blade is at one end of the diversion cavity, and the center of the turbine fan blade is on one side of the inner pipe channel.

[0011] Optionally, a multi-layer horn-shaped drainage plate is arranged in the inner wall of the diversion cavity.

[0012] Optionally, the device pipe body is an integrally injection-molded structure.

[0013] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0014] In the above solution, by setting the pressurization assembly, the jointly action of the inclined diversion plate and the annularly and equidistantly distributed flow holes enables the fluid to turn and accelerate multiple times when flowing through these structures, thereby realizing effective pressurization of the fluid. This pressurization method not only improves the head and flow rate of the fluid, but also reduces the dependence on the initial flow velocity of the water flow, enabling the system to maintain a good pressurization effect at different flow velocities. Due to the improvement of the pressurization effect, the circulating water pump no longer needs to increase the operating power or extend the operating time to maintain the required fluid flow velocity and pressurization effect of the system, thus greatly reducing the energy consumption of the system. This conforms to the modern design concept of energy conservation and consumption reduction, and helps to reduce the operating cost and environmental burden.

[0015] By optimizing the structural design of the pressurization component, the pressurization effect becomes more stable and reliable. This helps reduce system pressure fluctuations, improve the stability and reliability of the system, extend the service life of the equipment. The turbine fan blades arranged in the installation cavity formed between the other side of the inner pipe and the inner wall of the device pipe body can be driven to rotate when the fluid flows, further accelerating the fluid and generating an additional pressurization effect. This design enhances the pressurization ability of the pressurization device, enabling it to adapt to a wider range of working conditions. The multi-layer trumpet-shaped drainage plates arranged on the inner wall of the diversion cavity help guide the fluid into the pressurization area more smoothly and reduce the energy loss of the fluid during the flow process. This design further improves the pressurization efficiency, allowing the fluid to pass through the pressurization device more efficiently.

[0016] In the above solution, the device pipe body adopts an integrally injection-molded structure, which not only improves the overall strength and durability of the equipment, but also simplifies the manufacturing process and reduces the manufacturing cost. At the same time, this structure also helps reduce the maintenance workload of the equipment and lower the maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will describe in detail a high-efficiency circulating water pump fluid energy-saving pressurization device provided by the present invention in conjunction with the accompanying drawings and specific embodiments; at the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some well-known technologies, those skilled in the art can also adopt other alternative methods.

[0024] As Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides a high-efficiency circulating water pump fluid energy-saving pressurization device, including a device pipe body 1, and connecting flanges 2 are fixedly connected to both ends of the device pipe body 1; a pressurization component, which is used for energy-saving pressurization of the fluid. The pressurization component is connected to the device pipe body 1. The pressurization component includes a diversion cavity 101 opened in the inner wall of the device pipe body 1. An inner pipe 103 is provided between the diversion cavity 101 and the flow cavity of the device pipe body 1. An inclined diversion plate 3 is fixedly connected to the inner wall of the inner pipe 103. A plurality of flow holes 105 are opened in the inner wall of the inner pipe 103 and are distributed equidistantly in a ring. The flow holes 105 communicate the diversion cavity 101 with the flow cavity. The flow holes 105 are located on one side of the diversion plate 3, and the diversion plate 3 is inclined towards the flow holes 105. A spiral-shaped drainage groove 104 is opened on the inner wall of the diversion plate 3. One end of the inner pipe 103 is fixedly connected to one side of the inner wall of the device pipe body 1. An installation cavity is provided between the other side of the inner pipe 103 and the inner wall of the device pipe body 1. A cross-shaped mounting frame 5 is fixedly connected to the inner wall of the installation cavity. A turbine fan blade 4 is rotatably connected inside the cross-shaped mounting frame 5. The edge of the turbine fan blade 4 is at one end of the diversion cavity 101, and the center of the turbine fan blade 4 is on one side of the inner pipe 103 channel. A multi-layered horn-shaped drainage plate 102 is provided in the inner wall of the diversion cavity 101. The fluid first enters the device through the connecting flanges 2 at both ends of the device pipe body 1. The connecting flanges 2 ensure that the device can be conveniently installed into the circulating system. After the fluid enters the device, it first encounters the multi-layered horn-shaped drainage plates 102. The design of these drainage plates 102 helps to guide the fluid to enter the diversion cavity 101 evenly and smoothly, reducing fluid impact and energy loss. As the fluid enters the diversion cavity 101, it impacts the edge of the turbine fan blade 4. The turbine fan blade 4 starts to rotate under the action of the fluid, and its rotation direction causes the fluid to form a rotating flow in the diversion cavity 101. The rotation of the turbine fan blade 4 not only accelerates the fluid but also produces an additional pressurization effect. When the fluid passes through the diversion plate 3, since the diversion plate 3 is inclined, the fluid is forced to change its flow direction and accelerate through. At the same time, the spiral-shaped drainage groove 104 on the inner wall of the diversion plate 3 further guides the fluid to rotate and accelerate, increasing the kinetic energy of the fluid. The accelerated fluid enters the flow cavity of the device pipe body 1 through a plurality of flow holes 105 distributed equidistantly in a ring.Since the flow hole 105 is located on one side of the flow dividing plate 3, and the flow dividing plate 3 is inclined towards the flow hole 105, this design enables the fluid to maintain a high flow rate and kinetic energy when passing through the flow hole 105. The fluid entering the flow cavity through the flow hole 105 mixes with the original fluid to form a fluid with a higher flow rate and pressure, and then is output through the other end of the device body 1. By changing the fluid flow direction and accelerating the fluid, the kinetic energy and pressure boosting effect of the fluid are improved. The flow hole 105 connects the flow dividing cavity 101 and the flow cavity, enabling the accelerated fluid to enter the flow cavity and mix with the original fluid, ensuring the smooth flow and efficient mixing of the fluid, increasing the flow rate and pressure of the output fluid. The turbine fan blade 4 rotates under the impact of the fluid, generating an additional pressure boosting effect; the cross mounting bracket 5 is used to fix the turbine fan blade 4 to ensure its stable rotation. By rotating to accelerate the fluid, the pressure boosting capacity and efficiency of the pressure boosting device are improved. The multi-layer trumpet-shaped flow guiding plate 102 guides the fluid to enter the flow dividing cavity 101 evenly and smoothly, reducing fluid impact and energy loss, and improving the fluid flow efficiency and pressure boosting effect.

[0025] As Figures 1 to 4 shown, the device body 1 is an integrally injection-molded structure. Both ends of the device body 1 are fixedly connected with connecting flanges 2. The device body 1 adopts an integrally injection-molded structure, which has the characteristics of high strength and durability and can withstand the pressure and impact of the fluid. The inside of the pipe body is designed with a specific flow channel for guiding the fluid to flow along a predetermined path. The connecting flange 2 is a fixed connecting part at both ends of the device body 1, used to connect the device with other pipes or equipment in the circulation system. Flange connection has the advantages of good sealing performance, reliable connection, and convenient disassembly, and can ensure that the fluid does not leak during transmission. The fluid enters the inlet end of the device body 1 through the connecting flange 2. Inside the device body 1, the fluid flows along the designed flow channel and, through the action of the pressure boosting component, realizes the energy-saving pressure boosting of the fluid. The boosted fluid is output through the outlet end of the device body 1 and the connecting flange 2 and enters the next link of the circulation system. The integrally injection-molded structure enables the device body 1 to have higher strength and durability, can withstand greater fluid pressure and impact, and extends the service life of the equipment. The connecting flange 2 adopts a sealing design to ensure that the fluid does not leak during transmission, improving the safety and reliability of the system.

[0026] The working principle provided by the present utility model: Fluids enter the inlet end of the device tube body 1 through the connecting flange 2. Inside the device tube body 1, after the fluids enter the device, they first encounter multiple layers of horn-shaped diversion plates 102. The design of these diversion plates 102 helps to guide the fluids to enter the diversion cavity 101 evenly and smoothly, reducing fluid impact and energy loss. As the fluids enter the diversion cavity 101, they impact the edges of the turbine fan blades 4. The turbine fan blades 4 start to rotate under the action of the fluids, and their rotation direction causes the fluids to form a rotational flow within the diversion cavity 101. The rotation of the turbine fan blades 4 not only accelerates the fluids but also generates an additional pressurization effect. When the fluids pass through the diversion plate 3, since the diversion plate 3 is inclined, the fluids are forced to change their flow directions and accelerate through. At the same time, the spiral-shaped diversion grooves 104 distributed on the inner wall of the diversion plate 3 further guide the fluids to rotate and accelerate, increasing the kinetic energy of the fluids. The accelerated fluids enter the flow cavity of the device tube body 1 through multiple evenly distributed circular flow holes 105. Since the flow holes 105 are located on one side of the diversion plate 3 and the diversion plate 3 is inclined towards the flow holes 105, this design enables the fluids to maintain a relatively high flow rate and kinetic energy when passing through the flow holes 105. The fluids entering the flow cavity through the flow holes 105 are mixed with the original fluids, forming fluids with higher flow rates and pressures, and then are output from the other end of the device tube body 1. By changing the flow directions of the fluids and accelerating the fluids, the kinetic energy and pressurization effect of the fluids are improved. The flow holes 105 connect the diversion cavity 101 with the flow cavity, enabling the accelerated fluids to enter the flow cavity and be mixed with the original fluids, ensuring the smooth flow and efficient mixing of the fluids, and increasing the flow rate and pressure of the output fluids. The turbine fan blades 4 rotate under the impact of the fluids, generating an additional pressurization effect; the cross mounting bracket 5 is used to fix the turbine fan blades 4 to ensure their stable rotation, accelerating the fluids through rotation, and improving the pressurization capacity and efficiency of the pressurization device.

It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
