[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Please refer to Figs. 1 to 3 The utility model provides a technical scheme: a different flow combination device of same head variable flow pump group, include: pump unit 100 and pipeline assembly 200, pump unit 100 and pipeline assembly 200 are connected with each other for changing water flow, pump unit 100 includes the pump machine spare for combining different flow, and the pump machine spare is connected with booster spare through hose, and pipeline assembly 200 includes the main pipe 210 for connecting pump unit 100, the outer surface of main pipe 210 is equipped with backflow pipe 220 for backflow to water body, and the water outlet end of main pipe 210 is equipped with secondary pipe 230.

[0023] Please refer to Figs. 1 to 3 As the first embodiment of the utility model: pump machine spare includes flow pump one 130, flow pump two and flow pump three, and the head of flow pump one 130, flow pump two and flow pump three is same but flow is different, and the flow of flow pump one 130 is greater than flow pump two, and the flow of flow pump two is greater than flow pump three.

[0024] The booster spare includes booster column 110 and bottom plate 101, and the upper side surface of bottom plate 101 is equipped with booster column 110, and the outer surface of booster column 110 is connected with pump machine spare through valve one 131 and hose;

[0025] The upper side surface of booster column 110 is equipped with pipeline 120, and the outer surface of pipeline 120 is equipped with valve two 121, and one end of pipeline 120 away from booster column 110 is connected with the outer surface of main pipe 210.

[0026] The outer surface of main pipe 210 is equipped with three valve threes 211, and the left two valve threes 211 are symmetrically arranged on the outer surface of main pipe 210, and three pipelines 120 are arranged between the left and right two valve threes 211 through main pipe 210.

[0027] In operation, the user first uses the upstream system to transport water through the pump assembly 100 to the pipeline assembly 200. When transporting water through the pump assembly 100 to the pipeline assembly 200, different pump components can be selected according to actual needs, or all pump components can be started. The pump components then transport water through the booster column 110 to the pipeline assembly 200, achieving variable flow rate adjustment at the same head. Since different pump components can provide different base flow rates, by combining these pump components, the required flow rate can be precisely adjusted according to changes in actual working conditions. Whether it's fine-tuning small-flow operations or rapid large-flow delivery, it can easily handle the flow requirements of various application scenarios. During actual operation, if fine-tuning of the flow rate is required, it can be achieved by turning on or off specific pump components, eliminating the need to replace the entire pump for adjustment operations, as is often the case with traditional systems. This makes operation more convenient and efficient.

[0028] Please see Figs. 1 to 3 As a second embodiment of this utility model: a return pipe 220 is installed between the two symmetrical valves 211 on the left through a main pipe 210. The return pipe 220 has a U-shaped structure. The end of the return pipe 220 away from the valve 211 is connected to the main pipe 210 and is located on the right side of the valve 211 on the right.

[0029] Valve 221 is installed at both ends of the return pipe 220 and the main pipe 210. Valve 131, valve 212, valve 321 and valve 421 are all electronic flow valves. A secondary pipe 230 with an L-shaped structure is installed at the outlet end on the left side of the main pipe 210.

[0030] The end of the secondary pipe 230 furthest from the main pipe 210 is connected to the lower-level system, and the pump assembly 100 is connected to the upper-level system;

[0031] In use, when water is supplied to the pipe assembly 200 through the operation steps of the first embodiment, the user can close valve 3 211 on the right side of the outer surface of the main pipe 210 and open the two valves 3 211 on the left side of the outer surface of the main pipe 210, allowing the water supplied to the main pipe 210 to be transferred to the secondary pipe 230. While transferring to the secondary pipe 230, valve 4 221 between the main pipe 210 and the return pipe 220 is closed, allowing the water in the main pipe 210 to be transferred to the secondary pipe 230. Since the main pipe 210 is connected to the pump assembly 100, the water output from the pump can be centrally transported. By connecting and combining with different pump assemblies 100, the water flow rate in the main pipe 210 can be flexibly adjusted according to actual needs. The secondary pipe 230 further increases the flexibility of flow regulation. The active flow pipe 220 can divert a portion of the water in the main pipe 210 to the secondary pipe 230, achieving flow distribution in different branches and meeting the differentiated water flow requirements of different areas or equipment. Simultaneously, when pump components start, stop, or experience sudden flow changes, pressure fluctuations can easily occur. The return pipe 220 can return a portion of the water when the pressure rises, alleviating the pressure increase trend in the main pipe 210. When the pressure decreases, it can also replenish a certain amount of water through return flow, stabilizing the pressure in the main pipe 210, reducing the impact of pressure fluctuations on the system, protecting pipeline 120, pumps, and other equipment, and improving the stability and safety of the system. (In actual use, valves 131, 121, 211, 221, and 221, as well as pump components, are all existing technologies, and their models can be selected from existing market models, which will not be elaborated here.)

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
