Description

Technical Field

[0001] This utility model relates to the technical field of fluid control equipment, and more specifically, to a water pump connection system and a hydraulic module. Background Technology

[0002] A hydraulic module is a device that integrates various hydraulic components such as a water pump, valve assembly, filter, and constant pressure water supply device. It is mainly used in HVAC systems. It can realize the control, regulation, and distribution functions of the hydraulic system, improve the system's operating efficiency and stability, and facilitate installation, maintenance, and management.

[0003] Existing hydraulic modules have bottlenecks in complex application scenarios. For example, in villas, the scalability of pump sets is insufficient, and traditional dual-pump systems cannot meet the demand for ultra-high flow rates. To meet the demand for ultra-high flow rates, traditional dual-pump systems are replaced with multi-pump parallel systems. However, traditional multi-pump parallel systems require a common manifold, and differences in pipe resistance in the common manifold can easily lead to hydraulic imbalance. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that are prone to hydraulic imbalance when meeting ultra-high flow rate requirements, and to provide a water pump connection system and hydraulic module that can meet ultra-high flow rate requirements while avoiding hydraulic imbalance.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A water pump connection system is provided, including a first water pump, a second water pump, a third water pump, an inlet pipe, and an outlet pipe. The first inlet of the first water pump is connected to the second inlet of the second water pump, the second inlet is connected to the third inlet of the third water pump, and the inlet pipe is connected to the first inlet. The first outlet of the first water pump is connected to the second outlet of the second water pump, the second outlet is connected to the third outlet of the third water pump, the third outlet is connected to the first outlet, and the outlet pipe is connected to the first outlet, the second outlet, and the third outlet.

[0007] This utility model relates to a water pump connection system where the first outlet of the first water pump is connected to the second outlet of the second water pump, the second outlet is connected to the third outlet of the third water pump, and the third outlet is connected to the first outlet. In other words, the outlets of the first, second, and third water pumps are interconnected in pairs, forming a delta-shaped parallel connection. Compared to the single confluence point of traditional parallel connections, the delta-shaped structure allows the fluid to form a diversion-convergence circulation in the pipeline, effectively balancing the outlet pressure of each pump. When the system resistance changes, the delta-shaped structure can automatically adjust the flow distribution through internal circulation, avoiding the "water grabbing" phenomenon caused by differences in pipeline resistance in traditional parallel connections. This allows for meeting ultra-high flow requirements while preventing hydraulic imbalance.

[0008] Furthermore, the system also includes a radiant pump, the fourth inlet of which is connected to the third inlet, the fourth outlet of which is connected to the third outlet, and the fourth outlet is connected to the outlet pipe. By introducing the radiant pump, the system can more flexibly adjust the flow distribution between the main circuit and the radiant terminals.

[0009] Furthermore, it also includes a backup main pump, the fifth inlet of which is connected to the third inlet, and the fifth outlet of which is connected to the third outlet. By setting up a backup main pump, the backup main pump can be started to take over the load when the first, second, or third pump fails.

[0010] Furthermore, flow meters are installed at the first, second, and third water outlets. By installing flow meters, the flow rates of the first, second, and third water pumps can be detected, thereby facilitating the dynamic adjustment of the speeds of the first, second, and third water pumps.

[0011] Furthermore, pressure sensors are installed at the connection points between the first and second water outlets, the second and third water outlets, and the third and first water outlets. By setting pressure sensors to detect the pressure at the three nodes of the triangular loop, it is convenient to quickly locate the fault point.

[0012] This utility model also provides a hydraulic module, including a housing, a water tank, and the water pump connection system described above. Both the water pump connection system and the water tank are located inside the housing, and the water inlet pipe is connected to the water tank.

[0013] The hydraulic module of this utility model has a water pump connection system that allows water to enter from the water tank through the water inlet pipe and supply water through the water pump connection system.

[0014] Furthermore, the first, second, and third water pumps are arranged in a triangular configuration. This triangular arrangement ensures that the first, second, and third water pumps are installed close together.

[0015] Furthermore, the housing includes a frame, a left panel, and a right panel. The frame has a maintenance port. Both the left and right panels are rotatably connected to the frame and are located at the maintenance port. The water tank is located on the left panel, and the water pump connection system is located on the right panel. The first, second, and third water pumps are all mounted and connected to the frame. By setting up the left and right panels, the water tank can be maintained independently when the left panel is opened, and the first, second, and third water pumps can be maintained independently when the right panel is opened.

[0016] Furthermore, the housing also includes a mounting bracket and a maintenance panel. The mounting bracket is mounted on the frame, and the maintenance panel is detachably connected to the mounting bracket. The first water pump, the second water pump, and the third water pump are all mounted on the maintenance panel. By providing the maintenance panel, when a water pump malfunctions, it is only necessary to disconnect the water pipes at both ends of the water pump from the pump, and the water pump can be removed for repair by disassembling the maintenance panel.

[0017] Furthermore, the maintenance panel includes a first maintenance panel, a second maintenance panel, and a third maintenance panel. All three panels are plugged into the mounting bracket. They are located at different heights. The first water pump is mounted on the first maintenance panel, the second water pump on the second maintenance panel, and the third water pump on the third maintenance panel. Positioning the first, second, and third maintenance panels at different heights facilitates disassembly and maintenance of the water pumps while maintaining a compact overall structure for the hydraulic module.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model discloses a water pump connection system and hydraulic module. By interconnecting the outlets of a first, second, and third water pump in pairs to form a delta-shaped parallel connection, compared to the single confluence point of traditional parallel connections, the delta-shaped structure enables the fluid to form a diversion-convergence circulation in the pipeline, effectively balancing the outlet pressure of each water pump. When the system resistance changes, the delta-shaped structure can automatically adjust the flow distribution through internal circulation, avoiding the "water grabbing" phenomenon caused by differences in pipeline resistance in traditional parallel connections. Thus, it can meet the demand for ultra-high flow rates while avoiding hydraulic imbalance. Attached Figure Description

[0026] Example 1

[0027] This embodiment is the first embodiment of the water pump connection system, such as Figure 1 As shown, the system includes a first water pump 110, a second water pump 120, a third water pump 130, an inlet pipe 140, and an outlet pipe 150. The first inlet 111 of the first water pump 110 is connected to the second inlet 121 of the second water pump 120, and the second inlet 121 is connected to the third inlet 131 of the third water pump 130. The inlet pipe 140 is connected to the first inlet 111. The first outlet 112 of the first water pump 110 is connected to the second outlet 122 of the second water pump 120, and the second outlet 122 is connected to the third outlet 132 of the third water pump 130. The third outlet 132 is connected to the first outlet 112. The outlet pipe 150 is connected to all three outlets: the first outlet 112, the second outlet 122, and the third outlet 132. Specifically, all connecting pipes use double O-ring seals, with a leakage rate of less than 0.001% per year.

[0028] The system also includes a radiant pump 160. The fourth inlet 161 of the radiant pump 160 is connected to the third inlet 131, and the fourth outlet 162 of the radiant pump 160 is connected to the third outlet 132. The fourth outlet 162 is also connected to the outlet pipe 150. By introducing the radiant pump 160, the system can more flexibly adjust the flow distribution between the main loop and the radiant terminals. The radiant pump 160 can be controlled independently to meet the flow requirements of specific areas, such as the flow requirements of local heating or cooling terminals, while the main pump focuses on maintaining the pressure and flow balance of the main loop. This division of labor allows the system to adapt to more complex load changes and improves overall operating efficiency. The radiant pump 160 is independently frequency-controlled, with a flow adjustment range of 5-20 m³ / h, used to compensate for terminal pressure loss. Specifically, the radiant pump 160 uses a low-flow, high-lift pump, such as a pipeline pump. Low-flow, high-lift pumps have a small flow rate, allowing for more precise control. They are placed in locations with long transport pipelines, making them highly efficient in water treatment systems requiring long-distance transport or liquid lifting.

[0029] In this embodiment, during periods of low flow, the second water pump 120 and the third water pump 130 can be shut down, leaving only the radiant pump 160 running.

[0030] It also includes a backup main pump 170, whose fifth inlet 171 is connected to the third inlet 131, and whose fifth outlet 172 is connected to the third outlet 132. By setting up the backup main pump 170, it is not started during normal use, but is activated to take over the load when the first pump 110, second pump 120, or third pump 130 fails.

[0031] The working principle of a water pump connection system in this embodiment is as follows:

[0032] The first outlet 112 of the first pump 110 is connected to the second outlet 122 of the second pump 120. The second outlet 122 is connected to the third outlet 132 of the third pump 130. The third outlet 132 is connected to the first outlet 112. In other words, the outlets of the first pump 110, the second pump 120, and the third pump 130 are interconnected in pairs, forming a delta-shaped parallel connection. Compared to the single confluence point of traditional parallel connections, the delta structure allows the fluid to form a diversion-convergence circulation in the pipeline, effectively balancing the outlet pressure of each pump. When the system resistance changes, the delta structure can automatically adjust the flow distribution through internal circulation, avoiding the "water grabbing" phenomenon caused by differences in pipeline resistance in traditional parallel connections. The "water grabbing" phenomenon is the overload of some pumps and the underload of others, thus meeting the demand for ultra-high flow rates while avoiding hydraulic imbalance.

[0033] Example 2

[0034] This embodiment is a second embodiment of a water pump connection system. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 1 As shown, flow meters 180 are installed at the first outlet 112, the second outlet 122, and the third outlet 132. By installing flow meters 180, the flow rates of the first pump 110, the second pump 120, and the third pump 130 are detected, thereby facilitating the dynamic adjustment of the speeds of the first pump 110, the second pump 120, and the third pump 130.

[0035] Pressure sensors 190 are installed at the connections between the first outlet 112 and the second outlet 122, the second outlet 122 and the third outlet 132, and the third outlet 132 and the first outlet 112. By using pressure sensors 190 to detect the pressure at the three nodes of the delta circuit, the fault location can be quickly determined. In the delta structure, a fault in one pump will not affect the operation of the other pumps, and the fault location can be quickly determined using pressure sensors. In traditional parallel operation, if the outlet valve of one pump does not close tightly, it may cause abnormal flow in other pumps, requiring each pump to be shut down and tested sequentially.

[0036] Example 3

[0037] This embodiment is a first embodiment of a hydraulic module, such as... Figure 2 and Figure 3 As shown, it includes a housing 200, a water tank 300, and a water pump connection system 100 provided in Embodiment 1 or Embodiment 2. The water pump connection system 100 and the water tank 300 are both located inside the housing 200, and the water inlet pipe 140 is connected to the water tank 300.

[0038] The hydraulic module of this utility model has a water pump connection system 100 that receives water from the water tank 300 through the water inlet pipe 140 and supplies water through the water pump connection system 100.

[0039] The first water pump 110, the second water pump 120, and the third water pump 130 are arranged in a triangular configuration. This triangular arrangement ensures that the first water pump 110, the second water pump 120, and the third water pump 130 are tightly installed. Furthermore, in this embodiment, the outlets of all three water pumps face upwards, and with the aid of vertical pipes, the modules are installed closely side-by-side.

[0040] The housing 200 includes a frame 210, a left panel 220, and a right panel 230. The frame 210 has a maintenance port. Both the left panel 220 and the right panel 230 are rotatably connected to the frame 210 and are located at the maintenance port. The water tank 300 is located at the left panel 220, and the water pump connection system 100 is located at the right panel 230. The first water pump 110, the second water pump 120, and the third water pump 130 are all mounted and connected to the frame 210. By setting up the left panel 220 and the right panel 230, the water tank 300 can be maintained separately when the left panel 220 is opened, and the first water pump 110, the second water pump 120, and the third water pump 130 can be maintained separately when the right panel 230 is opened.

[0041] The housing 200 also includes a mounting bracket 240 and a maintenance panel 250. The mounting bracket 240 is mounted on the frame 210, and the maintenance panel 250 is detachably connected to the mounting bracket 240. The first water pump 110, the second water pump 120, and the third water pump 130 are all mounted on the maintenance panel 250. By using the maintenance panel 250, when a water pump malfunctions, it is only necessary to disconnect the water pipes at both ends of the water pump from the pump, and then remove the water pump for maintenance by disassembling the maintenance panel 250.

[0042] The maintenance panel 250 includes a first maintenance panel 251, a second maintenance panel 252, and a third maintenance panel 253. All three panels are plugged into the mounting bracket 240. The first, second, and third maintenance panels 251, 252, and 253 are located at different heights. A first water pump 110 is mounted on the first maintenance panel 251, a second water pump 120 is mounted on the second maintenance panel 252, and a third water pump 130 is mounted on the third maintenance panel 253. Positioning the first, second, and third maintenance panels 251, 252, and 253 at different heights allows for a compact overall hydraulic module structure while facilitating the disassembly and maintenance of the water pumps.
