Description

Technical Field

[0001] This utility model belongs to the field of liquid transportation technology, specifically a liquid pipeline control device. Background Technology

[0002] In many industrial fields such as oil extraction, chemical material transportation, and sewage treatment, it is often necessary to transport liquids by gravity. However, when transporting high-resistivity liquids such as lubricating oil and turbine oil by gravity, the transportation effect is not good due to the influence of drop, temperature and liquid viscosity. It is necessary to install pump equipment, such as shafted pumps and shaftless pumps, to achieve assisted transportation of liquids in pipelines.

[0003] Chinese patent CN218368244U discloses a shaftless pump propulsion device, including a housing, a rotor assembly, a power assembly, and a lubrication assembly. The housing has a supporting concave ring on its inner side, and the rotor assembly has a rotating toothed ring and a rotating convex ring on its outer side. The rotor assembly also has impellers on its inner side. A lubricating fluid channel is located inside the housing and connects to a fluid pressure space, while a lubricating fluid pipe is located on the housing and connects to the lubricating fluid channel, achieving water lubrication for the shaftless pump propulsion device. However, this shaftless pump propulsion device has a complex structure and suffers from insufficient intelligence when dealing with high-resistivity media such as lubricating oil and turbine oil. It struggles to automatically adjust operating parameters based on the real-time characteristics of the liquid, lacking adaptive capabilities, resulting in poor delivery performance and failing to meet the requirements for efficient and stable liquid delivery.

[0004] Therefore, there is an urgent need for a liquid pipeline control device to simplify the structure of the shaftless pump and automatically adjust the operating parameters of the shaftless pump through an intelligent control system, thereby improving the intelligence level and reliability of the conveying process and achieving efficient and stable liquid conveying. Utility Model Content

[0005] The purpose of this invention is to provide a liquid pipeline control device to solve at least one aspect of the problems and defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A liquid pipeline control device, comprising: Pipelines, shaftless pumps, and intelligent control systems; The shaftless pump includes a housing, a stator is provided on the inner wall of the housing, a rotor is provided inside the stator, an impeller is integrally provided inside the rotor, and blades are provided on the impeller; The inlet and outlet of the housing are respectively provided with flanges, and the shaftless pump is connected to the delivery pipeline through the flanges; A receiving control module is installed outside the housing, and the shaftless pump is connected to the intelligent control system through the receiving control module.

[0007] The liquid pipeline control device according to the present invention has at least the following technical effects: This liquid pipeline control device effectively eliminates the obstruction of the shaft to the liquid flow channel by installing a shaftless pump on the delivery pipeline, reducing the flow resistance of the liquid, especially for high-resistance media such as lubricating oil and turbine oil, allowing the liquid to flow more smoothly in the delivery pipeline. Compared with traditional shaftless pumps, it greatly simplifies the structure of the shaftless pump, effectively improving the liquid delivery efficiency. Furthermore, the shaftless pump integrates the impeller and motor rotor into a single design, reducing vulnerable components such as shafts and sealing devices, lowering the risk of wear and leakage, thereby reducing the frequency and cost of maintenance. At the same time, the intelligent control system can automatically adjust the operating parameters of the shaftless pump according to the real-time characteristics and operating conditions of the liquid. When the liquid viscosity changes, it can adjust the motor speed in a timely manner to ensure stable flow, improving the intelligence and reliability of the delivery process and achieving efficient and stable liquid delivery.

[0008] As a further embodiment of this invention, the blades are configured to have 4 to 8 blades.

[0009] By setting the blades to 4-8, and the angle between adjacent blades being gradually changed (i.e., the distance between adjacent blades near the rotor end is greater than the distance between adjacent blades away from the rotor end), the liquid can be pushed more smoothly when the blades rotate, effectively reducing the generation of liquid turbulence and vortices, preventing turbulence and vortices from consuming energy and increasing flow losses, thereby ensuring the efficiency of liquid delivery.

[0010] As a further improvement of this utility model, a filter screen is provided at the inlet end of the housing of the shaftless pump.

[0011] As a further improvement of this utility model, the filter screen has a pore size of 0.5mm-5mm.

[0012] High-resistivity liquids such as lubricating oil and turbine oil will contain a certain amount of solid particles after settling during use. If these particles directly enter the shaftless pump, they may accumulate in the impeller, blades, and flow channels, causing pump blockage. By installing a filter screen at the inlet end of the shaftless pump casing, larger particles can be effectively intercepted, preventing them from entering the pump body and ensuring smooth liquid flow within the pump, maintaining the normal operation of the shaftless pump. Furthermore, the pore size of this filter screen is 0.5mm-5mm, which can be selected according to the solid content and particle size of the high-resistivity liquid being pumped, allowing for more precise filtration of impurities, meeting the needs of different operating conditions, and improving the applicability and flexibility of the device.

[0013] As a further improvement of this utility model, the roughness of the inner wall of the shell is Ra0.2μm-Ra0.8μm.

[0014] Because the roughness of the inner wall of the housing is Ra0.2μm-Ra0.8μm, the flow resistance of the liquid in the housing can be effectively reduced, and the friction between the liquid and the inner wall of the housing can be reduced. Under the same power input, the liquid can pass through the pump body more smoothly, thereby increasing the liquid delivery volume per unit time and effectively improving the flow efficiency of the liquid in the delivery pipeline.

[0015] As a further embodiment of this invention, the intelligent control system includes an intelligent controller.

[0016] As a further embodiment of this utility model: a temperature sensor is provided at the inlet end of the conveying pipe near the shell, and a flow sensor is provided at the outlet end of the conveying pipe near the shell. The temperature sensor and the flow sensor are respectively connected to the intelligent controller.

[0017] As a further embodiment of this utility model: a pressure sensor is provided on the side of the conveying pipe near the temperature sensor, and a viscosity sensor is provided on the side of the conveying pipe near the flow sensor. The pressure sensor and the viscosity sensor are respectively connected to the intelligent controller.

[0018] Because the intelligent control system includes an intelligent controller, a temperature sensor is installed at the inlet end of the delivery pipeline near the shell, and a flow sensor is installed at the outlet end of the delivery pipeline near the shell. The temperature sensor and the flow sensor are connected to the intelligent controller. A pressure sensor is installed on the side of the delivery pipeline near the temperature sensor, and a viscosity sensor is installed on the side of the delivery pipeline near the flow sensor. The pressure sensor and the viscosity sensor are connected to the intelligent controller. By connecting the temperature sensor, flow sensor, pressure sensor, and viscosity sensor on the delivery pipeline to the intelligent controller, the intelligent control system can receive real-time data from these sensors and accurately adjust the operating parameters of the shaftless pump, such as motor speed and power, based on the data. This prevents certain parameters from exceeding the normal range during the liquid delivery process, which could damage the pipeline and equipment, and ensures the stability and reliability of liquid delivery.

[0019] As a further embodiment of this invention: the intelligent control system further includes a frequency converter, and the receiving control module of the shaftless pump is connected to the intelligent controller through the frequency converter.

[0020] Since the intelligent control system also includes a frequency converter, the receiving control module of the shaftless pump is connected to the intelligent controller through the frequency converter; this allows the motor speed to be adjusted by the frequency converter. The frequency converter receives the control signal sent by the intelligent controller and precisely adjusts the power supply frequency and voltage of the motor, thereby achieving rapid and accurate adjustment of the motor speed, which helps to improve the precision and stability of the production process and ensure the consistency of product quality.

[0021] As a further improvement of this invention, the blade is coated with a hydrophobic coating.

[0022] By coating the blades with a hydrophobic coating, preferably a fluoropolymer coating, liquids are made difficult to adhere to the blade surface, which can effectively reduce the friction and viscosity between the liquid and the blades. This reduces the energy consumed by the shaftless pump during liquid transportation, improves the overall efficiency of the pump, and thus improves the liquid transportation efficiency.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] like Figure 1-3The embodiment of this utility model shows a liquid pipeline control device, including: a delivery pipeline 1, a shaftless pump 2, and an intelligent control system 3; the shaftless pump 2 includes a housing 201, a stator 202 is provided on the inner wall of the housing 201, a rotor is provided inside the stator 202, an impeller is integrally provided inside the rotor, and blades 203 are provided on the impeller; flanges 204 are respectively provided at the inlet and outlet of the housing 201, and the shaftless pump 2 is connected to the delivery pipeline 1 through the flanges 204; a receiving control module 205 is provided outside the housing 201, and the shaftless pump 2 is connected to the intelligent control system 3 through the receiving control module 205.

[0033] Specifically, this liquid pipeline control device effectively eliminates the obstruction of the shaft to the liquid flow channel by installing a shaftless pump 2 on the delivery pipeline 1, reducing the flow resistance of the liquid, especially for high-resistance media such as lubricating oil and turbine oil, allowing the liquid to flow more smoothly in the delivery pipeline 1. Compared with traditional shafted pumps, it greatly improves the liquid delivery efficiency. Furthermore, the shaftless pump 2 integrates the impeller and motor rotor, reducing vulnerable parts such as shafts and sealing devices, lowering the risk of wear and leakage, thereby reducing the number of maintenance times and maintenance costs. At the same time, the intelligent control system 3 can automatically adjust the operating parameters of the shaftless pump 2 according to the real-time characteristics and operating conditions of the liquid. When the liquid viscosity changes, it can adjust the motor speed in time to ensure the stability of the flow rate, improving the intelligence level and reliability of the delivery process, and achieving efficient and stable liquid delivery.

[0034] Furthermore, the blade 203 is configured with 4 to 8 blades.

[0035] Specifically, by setting the blades 203 to 4-8 blades, and the included angle between adjacent blades 203 is gradually changing, that is, the distance between the ends of adjacent blades 203 closer to the rotor is greater than the distance between the ends of adjacent blades 203 farther from the rotor, the liquid can be pushed more smoothly when the blades 203 rotate, effectively reducing the generation of liquid turbulence and vortex, preventing turbulence and vortex from consuming energy and increasing flow loss, thereby ensuring the efficiency of liquid delivery.

[0036] Furthermore, the shaftless pump 2 has a filter screen at the inlet end of the housing 201, and the filter screen has a pore size of 0.5mm-5mm.

[0037] Specifically, high-resistivity liquid media such as lubricating oil and turbine oil will contain a certain amount of solid particles after settling during use. If these particles directly enter the shaftless pump, they may accumulate in the impeller, blades 203, flow channels, etc., causing pump blockage. By installing a filter screen at the inlet end of the casing 201 of the shaftless pump 2, larger particles can be effectively intercepted, preventing them from entering the pump body and ensuring smooth flow of liquid within the pump, maintaining the normal operation of the shaftless pump 2. Furthermore, the pore size of this filter screen is 0.5mm-5mm, which can be selected according to the solid content and particle size of the high-resistivity liquid being transported, allowing for more precise filtration of impurities, meeting the needs of different operating conditions, and improving the applicability and flexibility of the device.

[0038] Furthermore, the roughness of the inner wall of the shell 201 is Ra0.2μm-Ra0.8μm.

[0039] Specifically, since the roughness of the inner wall of the housing 201 is Ra0.2μm-Ra0.8μm, the flow resistance of the liquid in the housing 201 can be effectively reduced, and the friction between the liquid and the inner wall of the housing 201 can be reduced. Under the same power input, the liquid can pass through the pump body more smoothly, thereby increasing the liquid delivery volume per unit time and effectively improving the flow efficiency of the liquid in the delivery pipeline 1.

[0040] According to embodiments of the present invention, such as Figure 1 As shown, the intelligent control system 3 includes an intelligent controller 301. A temperature sensor 302 is installed on the inlet end of the conveying pipe 1 near the housing 201, and a flow sensor 303 is installed on the outlet end of the conveying pipe 1 near the housing 201. The temperature sensor 302 and the flow sensor 303 are respectively connected to the intelligent controller 301. A pressure sensor 304 is installed on the side of the conveying pipe 1 near the temperature sensor 302, and a viscosity sensor 305 is installed on the side of the conveying pipe 1 near the flow sensor 303. The pressure sensor 304 and the viscosity sensor 305 are respectively connected to the intelligent controller 301.

[0041] Specifically, since the intelligent control system 3 includes an intelligent controller 301, a temperature sensor 302 is installed at the inlet end of the conveying pipeline 1 near the housing 201, and a flow sensor 303 is installed at the outlet end of the conveying pipeline 1 near the housing 201. The temperature sensor 302 and the flow sensor 303 are respectively connected to the intelligent controller 301. A pressure sensor 304 is installed on the side of the conveying pipeline 1 near the temperature sensor 302, and a viscosity sensor 305 is installed on the side of the conveying pipeline 1 near the flow sensor 303. The pressure sensor 304 and the viscosity sensor 305 are respectively connected to the intelligent controller 301. By connecting the temperature sensor 302, the flow sensor 303, the pressure sensor 304, and the viscosity sensor 305 on the conveying pipeline 1 to the intelligent controller 301, the intelligent control system 3 can receive real-time data from these sensors and can accurately adjust the operating parameters of the shaftless pump 2, such as motor speed and power, according to the data. This prevents certain parameters from exceeding the normal range during the liquid conveying process in the conveying pipeline 1, which could lead to damage to the pipeline and equipment, and ensures the stability and reliability of liquid conveying.

[0042] Furthermore, such as Figure 1 As shown, the intelligent control system 3 also includes a frequency converter 306, and the receiving control module 205 of the shaftless pump 2 is connected to the intelligent controller 301 through the frequency converter 306.

[0043] Specifically, since the intelligent control system 3 also includes a frequency converter 306, the receiving control module 205 of the shaftless pump 2 is connected to the intelligent controller 301 through the frequency converter 306; this allows the motor speed to be adjusted through the frequency converter 306. The frequency converter 306 receives the control signal sent by the intelligent controller 301 and precisely adjusts the power supply frequency and voltage of the motor, thereby achieving rapid and accurate adjustment of the motor speed, which helps to improve the precision and stability of the production process and ensure the consistency of product quality.

[0044] It should also be noted that blade 203 is coated with a hydrophobic coating.

[0045] Specifically, by coating the blades 203 with a hydrophobic coating, preferably a fluoropolymer coating, the liquid is difficult to adhere to the surface of the blades 203, which can effectively reduce the friction and viscosity between the liquid and the blades 203, thereby reducing the energy consumed by the shaftless pump 2 in the process of transporting liquid, improving the overall efficiency of the pump, and thus improving the liquid transport efficiency.

[0046] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
