Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage, and in particular to a high-efficiency and energy-saving water pumping station. Background Technology

[0002] High-efficiency and energy-saving water pumping stations improve operational efficiency and reduce energy consumption through optimized design, high-efficiency pumps, intelligent control, and variable frequency technology. Combining renewable energy with intelligent management enables on-demand water supply, reducing waste and yielding significant economic and environmental benefits, representing the future direction of water conservancy development.

[0003] In water pumping stations, the static pressure and mass of the water must be considered when lifting and discharging water. This consumes a significant amount of energy and is a major factor affecting operational efficiency and energy consumption. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency and energy-saving water pumping station to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency and energy-saving water pumping station, comprising a base, a pumping station tank, an inlet, a gate, a pipe elbow, an air-assisted venturi tube, a lift-discharge pump, a drain outlet, and an operating platform. The pumping station tank is axially mounted on the base. The inlet is located at the lower rear of the side end of the pumping station tank. The gate is installed inside the pumping station tank via the inlet. The pipe elbow is installed with a downward opening at the gate. The air-assisted venturi tube is installed at the bottom opening of the pipe elbow. The lift-discharge pump is installed at the bottom of the pumping station tank. The drain outlet is installed at the upper front of the side end of the pumping station tank. The operating platform is installed in the middle of the pumping station tank.

[0006] Based on the above technical solution, the air-assisted venturi tube includes an inlet section, a throat, a diffuser, a diffuser mesh, an air pipe, and a bend negative pressure pipe. The inlet section is installed at the bottom opening of the pipe bend, the throat is installed at the bottom of the inlet section, the diffuser is installed at the bottom of the throat, the diffuser mesh is installed at the bottom of the diffuser, the rear end of the air pipe is radially inserted into the throat, and the front end of the air pipe is inserted into the pump station tank. The bend negative pressure pipe is installed downward through the inner opening of the throat into the air pipe.

[0007] Based on the above technical solution, the air-assisted venturi tube draws in air from the water entering the pump station tank and disperses it into the water to form bubbles.

[0008] Compared with the prior art, the present invention has the following advantages: The present invention installs an air-assisted Venturi tube at the inlet of the water pumping station, and through the Venturi effect, draws in air into the water entering the pumping station tank and disperses it into the water to form bubbles, thereby changing the liquid density, reducing weight, and breaking the static pressure of the water, thus reducing energy consumption when the lifting and discharge pumps are operating at the same time to lift and discharge water.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figs. 1 to 3 As shown, a high-efficiency and energy-saving water pumping station includes a base 1, a pumping station tank 2, an inlet 3, a gate 4, a pipe elbow 5, an air-assisted venturi tube 6, a lift-discharge pump 7, a drain outlet 8, and an operating platform 9. The pumping station tank 2 is axially mounted on the base 1. The inlet 3 is located at the lower rear of the side end of the pumping station tank 2. The gate 4 is installed inside the pumping station tank 2 through the inlet 3. The pipe elbow 5 is installed at the gate 4 with a downward opening. The air-assisted venturi tube 6 is installed at the bottom opening of the pipe elbow 5. The lift-discharge pump 7 is installed at the bottom of the pumping station tank 2. The drain outlet 8 is installed at the upper front of the side end of the pumping station tank 2. The operating platform 9 is installed in the middle of the pumping station tank 2.

[0015] The air-assisted venturi tube 6 includes an inlet section 10, a throat 11, a diffuser 12, a diffuser mesh 13, an air pipe 14, and a bent negative pressure pipe 15. The inlet section 10 is installed at the bottom opening of the pipe bend 5. The throat 11 is installed at the bottom of the inlet section 10. The diffuser 12 is installed at the bottom of the throat 11. The diffuser mesh 13 is installed at the bottom of the diffuser 12. The rear end of the air pipe 14 is radially inserted into the throat 11, and the front end of the air pipe 14 is inserted into the pump station tank 2. The bent negative pressure pipe 15 is installed downward through the inner opening of the throat 11 onto the air pipe 14.

[0016] The air-assisted venturi tube 6 draws in air into the water entering the pump station tank 2 and disperses it into the water to form bubbles.

[0017] The working principle of this utility model is as follows: Water is injected into the air-assisted Venturi tube 6 through the pipe elbow 5 by opening the gate 4 and the water inlet 3. When the water enters the throat 11 at the inlet section 10, the pressure in this area drops due to the increased flow velocity. At the same time, as the water continues to flow down, the negative pressure draws in air through the air pipe 14 via the elbow negative pressure pipe 15 and disperses it into the water to form bubbles. The water mixed with the bubbles enters the diffuser 12 and then passes through the diffuser net 13 and is fully diffused at the bottom of the pump station tank 2. At the same time, the operating lift discharge pump 7 lifts the water at the bottom of the pump station tank 2. The water whose liquid density is changed by the bubbles, which reduces its weight and breaks the static pressure, is more easily lifted and discharged by the lift discharge pump 7, reducing energy consumption and improving efficiency.

[0018] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
