Description

Technical Field

[0001] This utility model relates to the field of water supply technology, specifically to a high-efficiency and energy-saving constant pressure water supply module. Background Technology

[0002] Constant pressure water supply is a water supply method in a water conservancy system. Its core objective is to maintain a constant water supply pressure to ensure a balance between water supply and water consumption. Compared with traditional water supply systems, constant pressure water supply systems have advantages such as advanced technology, constant water pressure, convenient operation, reliable operation, energy saving, and high degree of automation.

[0003] The constant pressure water supply system used in water-cooled computer rooms mainly consists of a frequency converter, a water pump, and a water pressure sensor. The constant pressure water supply system compares the actual pressure detected by the water pressure sensor with the given pressure. When the pipeline pressure is insufficient, the frequency converter increases the output frequency, the water pump speed increases, the water supply increases, and the pipeline pressure is forced to rise. Conversely, the water pump speed decreases, the water supply decreases, the pipeline pressure drops, and the constant pressure water supply is maintained.

[0004] However, during constant pressure regulation in a constant pressure water supply system, frequent changes in pump speed can lead to higher energy consumption and increased operating costs. At the same time, frequent constant pressure regulation can cause unstable water intake for the pump, which can affect the service life of the pump blades and the overall operating efficiency, resulting in unstable water supply.

[0005] In view of this, we propose a high-efficiency and energy-saving constant pressure water supply module. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency and energy-saving constant pressure water supply module to solve the problem of high energy consumption in constant pressure water supply systems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-efficiency and energy-saving constant pressure water supply module includes a hydraulic module, an intelligent control module, a water inlet module, and an expansion module. The hydraulic module includes a frequency converter control system, a water storage tank, a water pump unit, and a set of accessories. The frequency converter control system is used to maintain a stable pressure at the outlet of the water supply pipeline. The water storage tank stores water for supply. The water pump unit draws water from the storage tank and transports it through the water supply pipeline. The set of accessories is used to adjust the water supply volume, water flow direction, and record water consumption. The intelligent control module is connected to the hydraulic module. The control module is used to control the water pump unit. The intelligent control module automatically adjusts the speed or start / stop status of the water pump unit according to the pressure value at the outlet of the water pump unit, thereby maintaining the water pressure in the water supply pipeline at a constant range within a preset range. The water inlet module is loaded onto the water pump unit. The water inlet module is used to improve the stability of the water pump unit's operation. The water inlet module can effectively reduce water flow fluctuations and improve the water inlet stability of the water pump. The expansion module is connected to the hydraulic module. The expansion module is used for user-customized function expansion. The expansion module expands the functions according to user needs, thereby improving the overall management level of the water supply system.

[0009] Preferably, the water storage tank is a diaphragm pressure tank or a negative pressure-free flow stabilizing tank;

[0010] The diaphragm pressure tank is equipped with a rubber diaphragm inside. The expansion and contraction of the rubber diaphragm can smooth out pressure fluctuations in the water supply system and reduce the frequency of start-up and shutdown of the water pump unit.

[0011] The negative pressure tank regulates water flow pressure by installing a vacuum compensator at the top of the tank. When water flows into the negative pressure tank, the water level gradually rises, and air is automatically discharged through the vacuum compensator, creating pressure. When the water output of the water pump unit increases or decreases, the negative pressure tank regulates the water flow and pressure by expanding or compressing the pressure inside the tank through the vacuum compensator.

[0012] Preferably, the complete set of accessories includes water supply accessories, metering equipment, water distribution equipment, and water treatment equipment;

[0013] Water supply accessories include various valves and faucets, used to regulate water volume and pressure, control water flow direction, and facilitate the maintenance of pipes, instruments and equipment after the flow is interrupted;

[0014] Metering equipment: water meter, used to measure and record water consumption;

[0015] Water distribution equipment includes terminal water distribution points for domestic, industrial, and fire-fighting water-using equipment;

[0016] Water treatment equipment: sedimentation, filtration, softening, and disinfection equipment, used to ensure that the water quality meets the requirements.

[0017] Preferably, the intelligent control module includes a water pressure sensor and a constant pressure water supply controller; the water pressure sensor is located at the outlet of the water pump unit, and both the water pressure sensor and the constant pressure water supply controller are connected to the frequency converter control system; the water pressure sensor at the outlet of the water pump unit monitors the outlet water pressure in real time. When the water pressure sensor detects that the outlet water pressure is lower or higher than the water pressure set by the frequency converter control system, the water pressure sensor sends an electrical signal to the frequency converter control system, and the frequency converter control system sends an electrical signal to control the constant pressure water supply controller to work. The constant pressure water supply controller automatically adjusts the speed or start / stop state of the water pump, thereby maintaining the water pressure in the water supply pipeline constant within the preset range, improving water supply efficiency and reducing water supply energy consumption.

[0018] Preferably, the water inlet module is equipped with a water inlet device located at the water inlet of the water pump unit. The water inlet device can effectively reduce water flow fluctuations, improve the water inlet stability of the water pump unit, and at the same time, help extend the service life of the water pump blades in the water pump unit and improve the overall water supply operating efficiency.

[0019] Preferably, the expansion module includes integrated water quality detection and energy consumption analysis. Integrated water quality detection can detect the purity of water to avoid the supply of dirty water and sewage; energy consumption analysis can monitor the energy consumption of each module of the water supply system in real time for optimization and adjustment or for maintenance and troubleshooting based on abnormal energy consumption.

[0020] Compared with the prior art, the beneficial effects of this utility model are: through modular operation, this utility model makes the water supply system simple in structure, easy to operate, reduces the energy consumption of water supply, improves the stability of water supply operation, and can meet the water supply needs in various complex environments, reduce operating costs, and improve water supply efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The constant pressure water supply system mainly consists of a frequency converter, a water pump, and a water pressure sensor. The constant pressure water supply system compares the actual pressure detected by the water pressure sensor with the given pressure. When the pipeline pressure is insufficient, the frequency converter increases the output frequency, the water pump speed increases, the water supply increases, and the pipeline pressure is forced to rise. Conversely, the water pump speed decreases, the water supply decreases, the pipeline pressure drops, and the constant pressure water supply is maintained.

[0029] However, during constant pressure regulation in a constant pressure water supply system, frequent changes in pump speed can lead to higher energy consumption and increased operating costs. At the same time, frequent constant pressure regulation can cause unstable water intake for the pump, which can affect the service life of the pump blades and the overall operating efficiency, resulting in unstable water supply.

[0030] like Figure 1 As shown, a high-efficiency and energy-saving constant pressure water supply module includes a hydraulic module 1, an intelligent control module 2, a water inlet module 3, and an expansion module 4. The hydraulic module 1 includes a frequency converter control system 11, a water storage tank 12, a water pump unit 13, and a set of accessories 14. The intelligent control module 2 is connected to the hydraulic module 1 and is used to control the water pump unit 13. The water inlet module 3 is loaded onto the water pump unit 13 and is used to improve the stability of the water pump unit 13's operation. The expansion module 4 is connected to the hydraulic module 1 and is used for user-customized function expansion.

[0031] Specifically, the frequency conversion control system 11 of the hydraulic module 1 is used to maintain stable pressure at the outlet of the water supply pipeline; the water storage tank 12 is used to store water for water supply; the water pump unit 13 is used to transport water, drawing water from the water storage tank 12 and transporting it through the water supply pipeline; the complete set of accessories 14 is used to adjust the water supply volume, water flow direction, and water consumption records; the water inlet module 3 is loaded onto the water pump unit 13, and the water inlet module 3 is used to improve the stability of the operation of the water pump unit 13. The water inlet module 3 can effectively reduce water flow fluctuations and improve the water inlet stability of the water pump; the intelligent control module 2 is connected to the hydraulic module 1, and the intelligent control module 2 automatically adjusts the speed or start / stop state of the water pump unit 13 according to the pressure value at the outlet of the water pump unit 13, thereby maintaining the water pressure in the water supply pipeline constant within a preset range; the expansion module 4 is connected to the hydraulic module 1, and the expansion module expands the functions according to user needs, thereby improving the overall management level of the water supply system;

[0032] Preferably, the water pump unit 13 in this utility model is a general term for the water pump and its related components, which is the prior art.

[0033] In this embodiment, the water storage tank 12 is a diaphragm pressure tank 121 or a negative pressure stabilizing tank 122;

[0034] Specifically, the diaphragm pressure tank 121 has a rubber diaphragm inside, which prevents water from contacting the tank wall, thus preventing rust inside the tank wall and condensation outside the tank, thereby improving the service life of the tank. At the same time, the expansion and contraction of the rubber diaphragm can smooth the pressure fluctuations of the water supply system and reduce the start-up and shutdown frequency of the water pump unit 13. The negative pressure tank has a vacuum compensator installed on the top of the tank to regulate the water flow pressure. When water flows into the negative pressure tank, the water level gradually rises, and air is automatically discharged through the vacuum compensator, forming pressure. When the water output of the water pump unit 13 increases or decreases, the negative pressure tank expands or compresses the pressure inside the tank through the vacuum compensator to regulate the water flow and pressure.

[0035] In this embodiment, the complete set of accessories 14 includes water supply accessories, metering equipment, water distribution equipment, and water treatment equipment;

[0036] Specifically, water supply accessories include various valves and faucets used to regulate water volume and pressure, control water flow direction, and facilitate maintenance of pipes, instruments, and equipment after flow interruption; metering equipment: water meters used to measure and record water consumption; water distribution equipment includes terminal water distribution points for domestic, industrial, and fire-fighting water supply equipment; and water treatment equipment: sedimentation, filtration, softening, and disinfection equipment used to ensure that the water quality meets requirements.

[0037] In this embodiment, the intelligent control module 2 includes a water pressure sensor 21 and a constant pressure water supply controller 22; the water pressure sensor 21 is located at the outlet of the water pump unit 13, and both the water pressure sensor 21 and the constant pressure water supply controller 22 are connected to the frequency conversion control system 11.

[0038] Specifically, the water pressure sensor 21 is located at the outlet of the water pump unit 13 to monitor the water pressure in real time. When the water pressure sensor 21 detects that the water pressure at the outlet is lower or higher than the water pressure set by the frequency conversion control system 11, the water pressure sensor 21 sends an electrical signal to the frequency conversion control system 11. The frequency conversion control system 11 sends an electrical signal to control the constant pressure water supply controller 22 to work. The constant pressure water supply controller 22 automatically adjusts the speed or start / stop status of the water pump, thereby maintaining the water pressure in the water supply pipeline constant within the preset range, improving water supply efficiency and reducing water supply energy consumption.

[0039] In this embodiment, the water inlet module 3 is provided with a water inlet device 31, which is located at the water inlet of the water pump unit 13;

[0040] Specifically, the water inlet device 31 is located at the water inlet of the water pump unit 13. The water inlet device 31 can effectively reduce water flow fluctuations, improve the water inlet stability of the water pump unit 13, and at the same time, help extend the service life of the water pump blades in the water pump unit 13 and improve the overall water supply operating efficiency.

[0041] Preferably, the water inlet device 31 adopts a straight pipe type water inlet device of existing technology. The straight pipe type water inlet device has a simple structure, can provide a stable water flow, reduce the impact of water flow fluctuations on the water pump unit 13, and improve water supply efficiency. The water inlet device 31 includes an inlet pipe, an inlet valve, and an inlet filter. The inlet pipe is responsible for introducing the water source into the water inlet device to ensure smooth water flow. The inlet valve is used to control the size of the water flow to ensure water flow regulation and flow control. The inlet filter filters out suspended solids, particles, microorganisms and other impurities in the water to ensure water quality.

[0042] In this embodiment, the expansion module 4 includes integrated water quality detection and energy consumption analysis;

[0043] Specifically, integrated water quality testing can detect the purity of water, preventing the supply of dirty or wastewater; energy consumption analysis can monitor the energy consumption of each module of the water supply system in real time, allowing for optimization and adjustment or troubleshooting based on abnormal energy consumption.

[0044] In use, the high-efficiency and energy-saving constant pressure water supply module of this utility model sets the water supply pressure through the frequency conversion control system 11 of the hydraulic module 1, and delivers water through the water pump unit 13. During the delivery process of the water pump unit 13, the water inlet component located at the water inlet of the water pump unit 13 reduces water flow fluctuations and improves the stability of the water inlet through the water inlet device 31. When the intelligent control module 2 at the water outlet of the water pump unit 13 detects through the water pressure sensor 21 that the water pressure is lower than the water pressure value set by the frequency conversion control system 11, the frequency conversion control system 11 starts the constant pressure water supply controller 22. The constant pressure water supply controller 22 increases the speed of the water pump unit 13 to increase the water supply volume, thereby increasing the water pressure. When the water pressure is higher than the set water pressure value, the constant pressure water supply controller 22 reduces the speed of the water pump unit 13 to reduce the water supply volume, thereby reducing the water pressure.
