Description

Technical Field

[0001] This utility model relates to the field of water pump supply system technology, specifically a dual-pump energy-saving constant pressure water supply control system based on flow feedback. Background Technology

[0002] In an era of increasingly scarce water and electricity resources, water and energy conservation have become important themes in building a sustainable society. A constant pressure water supply control system uses the network water pressure as a set parameter and automatically adjusts the pump motor speed by controlling the output frequency of the frequency converter, achieving closed-loop regulation of the network water pressure and ensuring the water supply system automatically maintains a constant pressure value.

[0003] According to the patent titled "A Constant Pressure Variable Frequency Water Pump Multi-channel Water Supply Control System" (Patent Publication No.: CN206308748U, Patent Publication Date: 2017-07-07), it includes a water pump and a constant pressure variable frequency controller. The water pump is connected to several water supply branches and a water storage tank. Solenoid valve control devices and pressure / flow control devices are installed on the water supply branches, and a water level control device is installed in the water storage tank. The constant pressure variable frequency controller also includes a conversion module, and the solenoid valve control devices, pressure / flow control devices, and water level control devices are all electrically connected to the conversion module. The system collects real-time data on the pressure of the water supply pipelines and the water level in the water tank. Based on the collected information, it controls the start-up and operating frequency of the water pump, and controls the solenoid valve control devices to control the water flow rate in the pipeline. This saves manpower and resources, and provides fast control response and high efficiency. By receiving real-time information from the water supply system through a communication interface module or wireless communication module, the system's operating status can be remotely controlled and monitored.

[0004] Based on the aforementioned existing technologies, the current dual-pump energy-saving constant pressure water supply control system based on flow feedback still has the following problems: In traditional systems, after water enters the pipeline, impurities in the water are prone to clogging the flow sensor, valve and pump body flow channel. Impurities adhere to the inner wall of the flow meter and change the flow channel cross-section, causing the measured value to deviate from the actual flow. Therefore, this utility model provides a dual-pump energy-saving constant pressure water supply control system based on flow feedback. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-pump energy-saving constant pressure water supply control system based on flow feedback, comprising a conveying mechanism, wherein the conveying mechanism is internally equipped with a set of filtering mechanisms for filtering water, the filtering mechanisms comprising:

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.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A flow feedback-based dual-pump energy-saving constant pressure water supply control system includes a conveying mechanism 1. The conveying mechanism 1 has an internal filtration mechanism 2 for filtering the water. The filtration mechanism 2 includes:

[0025] The backwashing unit 21 is located inside the conveying mechanism 1 and is used to backwash the filter unit 22.

[0026] The filter unit 22 is located inside the conveying mechanism 1 and includes a cleaning filter cylinder 221. A perforated plate 222 and a filter plate 223 are fixedly installed inside the cleaning filter cylinder 221, and activated carbon is placed between the perforated plate 222 and the filter plate 223. The water is filtered through the activated carbon and the filter plate 223.

[0027] By incorporating a perforated plate 222, a filter plate 223, and an activated carbon layer within the filter cartridge 221, dual filtration (physical interception and chemical adsorption) is achieved for impurities in the water, such as sediment, rust, and algae. The activated carbon effectively removes organic matter, pigments, and chlorides, significantly reducing the risk of impurities clogging flow sensors, valves, and pump channels, ensuring the accuracy of flow measurement, and extending the equipment's service life.

[0028] In this embodiment, a discharge pipe 226 is fixedly installed on the front side of the filter cylinder 221, and a discharge cover 227 is fixedly installed on the front side of the discharge pipe 226 by bolts, which is used to discharge the activated carbon between the mesh plate 222 and the filter plate 223.

[0029] The discharge pipe 226 and the detachable discharge cover 227 on the front side of the filter cartridge 221 facilitate the rapid discharge of ineffective activated carbon, simplify the maintenance process, reduce downtime, improve system maintenance efficiency, and reduce manual cleaning costs.

[0031] The modular design of the feed pipe 224 and feed cover 225 supports convenient replenishment of activated carbon. The filling operation can be completed without disassembling the entire filter unit, which improves the maintainability of the system and ensures continuous and stable filtration performance.

[0032] In this embodiment, the backwashing unit 21 includes a water pump 211, and an inlet pipe 212 is fixedly installed at the input end of the water pump 211. A first valve 213 and a second valve 214 are fixedly installed at one end of the inlet pipe 212.

A connecting pipe 216 is fixedly installed at one end of the second valve 214. A branch pipe 217 is fixedly connected to the top of the water pump 211 through a pipe. A third valve 218 and a fourth valve 219 are fixedly installed on both sides of the connection between the branch pipe 217 and the pipe at the top of the water pump 211. A drain pipe 2110 is fixedly installed at one end of the fourth valve 219. The branch pipe 217 is fixedly connected to the inlet pipe 212.

[0033] The water pump 211 is model PUN-201. The first valve 213 is closed, the second valve 214 is open, the third valve 218 is open, and the fourth valve 219 is closed. The water pumped by the water pump 211 enters from the top of the filter cartridge 221 through the branch pipe 217, and then exits through the connecting pipe 215, the second valve 214, and the connecting pipe 216 to achieve filtration.

The water pumped by the water pump 211 enters the bottom of the inner cavity of the filter cartridge 221 through the inlet pipe 212, the first valve 213, and the connecting pipe 215 to backwash the activated carbon and filter plate 223. The backwashed water is discharged through the branch pipe 217, the fourth valve 219, and the drain pipe 2110, thereby achieving backwashing of the inside of the water pump 211.

[0034] In this embodiment, the conveying mechanism 1 includes a combination frame 11, and the water pump 211 and the filter cartridge 221 are both fixedly installed on the bottom plate of the combination frame 11.

[0035] The assembly frame 11 integrates the water pump 211, filter cartridge 221, controller 12, frequency converter 13, and delivery pipe assembly into a single unit, featuring a compact structure that facilitates installation and maintenance. The coordinated operation of the controller and frequency converter dynamically adjusts the water pump speed based on flow feedback, achieving constant pressure water supply while significantly reducing energy consumption and reaching energy-saving goals. Flow meters and throttling valves are respectively installed on the surfaces of the first delivery pipe assembly 14 and the second delivery pipe assembly 15. The flow meters detect the water supply pressure; if the pressure is insufficient, both assemblies 2 operate synchronously to boost the water supply.
