Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically to a water hub mixing pump station with a flow meter. Background Technology

[0002] Water pumping stations play a crucial role in HVAC water systems, installed between heat sources and terminal equipment to regulate the flow rate and temperature received at the terminals. In the early stages of development, the core components of a pumping station consisted of a single water pump and a few instruments, primarily functioning to deliver refrigerant and providing some variable flow capacity. As the temperature requirements of terminal equipment for refrigerant diversified, pumping stations gradually added mixing functions, precisely adjusting the supply water temperature to meet operational needs by mixing water flows of different temperatures. The rise of IoT technology has further propelled the automation of pumping stations, enabling real-time monitoring and automatic control through sensors and controllers, reducing manual intervention while improving system efficiency and reliability.

[0003] In addition, modern pumping stations emphasize energy conservation and environmental protection, adopting technologies such as variable frequency control to dynamically adjust the operating status according to actual needs, reduce energy consumption and optimize resource utilization. These technological advancements have enabled pumping stations to gradually evolve from simple conveying devices into multifunctional, intelligent and efficient key components.

[0004] Pump stations play a crucial role in HVAC systems, responsible for regulating the flow rate and temperature received by terminal equipment. Their structure typically includes four pipe interfaces: heat source supply water, heat source return water, terminal supply water, and terminal return water. The pump is usually installed between the heat source supply water and the terminal supply water, providing the system's flow power. A three-way valve is installed before the pump and after the heat source supply water, with its third interface connecting the pipeline between the terminal return water and the heat source return water. By adjusting the opening of the three-way valve, the heat source supply water and the terminal return water are mixed, regulating the water temperature supplied to the terminal. With the development of IoT technology, pump stations have achieved automated control. Sensors collect data such as temperature, pressure, and flow rate in real time. The control system analyzes this data and automatically adjusts the opening of the three-way valve and the operating status of the pump to achieve precise mixing and variable flow control, improving system efficiency and reliability. However, in existing technologies, when the pump station installation environment is not ideal, it is impossible to obtain whether the terminal flow rate meets energy requirements during commissioning. After construction, it is difficult to quickly replace damaged sensors and other components, and the insulation effect is poor. Summary of the Invention

The control mechanism 4 is connected to the flow meter 2 and a moving end 5 respectively, and an EPP insulation inner shell 6 is installed inside the EPP insulation structure 3. A positioning bracket 7 is installed on the side of the EPP insulation structure 3 away from the control mechanism 4.

[0027] The water circuit component 1 includes an inlet pipe 11 and a return pipe 12. A water pump 13 is installed on the inlet pipe 11, and an electric three-way valve 14 connected to the return pipe 12 is installed on the inlet pipe 11 and at the lower end of the water pump 13. A flow meter 2 is installed on the return pipe 12.

[0028] The water pump 13 is used to draw warm water, and the electric three-way valve 14 is used to connect the return water into the inlet pipe 11 to achieve temperature control.

[0029] As can be seen, the lower end of the water inlet pipe 11 is provided with a universal end valve 15, which is fixed by a union nut valve joint 16.

[0030] Furthermore, the water pump 13 and the electric three-way valve 14 are respectively connected to the control mechanism 4, and the control mechanism 4 is also connected to a temperature sensor 8 for detecting water temperature and a pressure sensor 9 for detecting water pressure.

[0031] In detail, the EPP insulation structure 3 includes an EPP insulation rear cover plate 31 and an EPP insulation front cover plate 32. A positioning groove 33 is provided between the EPP insulation rear cover plate 31 and the EPP insulation front cover plate 32 for the water circuit assembly 1 to be embedded. The EPP insulation inner shell 6 is provided with a clearance gap 61 for the water pump 13 and the electric three-way valve 14 to pass through.

[0032] It adopts a double-layer insulation wrapping and clamping, and together with the EPP insulation inner shell 6, it forms a three-section EPP insulation design, which improves the insulation effect, ensures the water flow temperature, and reduces heat loss.

[0033] Preferably, the EPP insulation back cover plate 31 and the EPP insulation front cover plate 32 are connected by an insertion, and the EPP insulation back cover plate 31 is provided with a plurality of connection holes 34 in the circumferential direction.

[0034] This design facilitates disassembly, assembly, maintenance, and replacement of parts.

[0040] Setting an isolation gap 74 allows the positioning bracket 7 to detach from the EPP insulation back cover 31, reducing heat conduction.

[0041] In summary, the principle of this embodiment is as follows: During the installation and commissioning phase, the commissioning engineer can read the flow rate through the pump station via the mobile terminal 5, thereby quickly locating the problem area; when the equipment is running for a long time, if components such as sensors fail, all components can be replaced simply by opening the EPP insulation front cover 32, the control box 41, and the EPP insulation inner shell 6, without having to disassemble the entire pump station for repair; during equipment operation, the flow meter 2 can monitor the system flow rate, thereby improving the control over the system.
