Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump with stability and reliability. Background Technique

[0002] When the water pump is running, the liquid enters through the water inlet pipe at the bottom of the water pump. After the water pump stops running, the water inside the water inlet pipe will flow back, resulting in water interruption inside the water inlet pipe.

[0003] The water interruption inside the suction pipe of the water pump will cause bubbles or air accumulation in the suction pipe, which will affect the normal operation of the water pump. When the design of the suction pipe is not properly considered or the vacuum value inside the suction pipe reaches a certain value, the dissolved gas in the water will continuously escape due to the decrease in pressure inside the pipe, forming air bags. These air bags may affect the water passing capacity, and in severe cases, they may even destroy the vacuum water absorption, resulting in abnormal operation of the water pump.

[0004] Therefore, we propose a water pump with stability and reliability. Content of the Utility Model

Detailed implementation mode

[0023] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0024] This embodiment is a water pump with stability and reliability.

[0025] As Figures 1-4 shown, it includes a water pump 1. An inlet pipe 5 is fixedly installed on the outer surface of the lower end of the water pump 1. An outlet pipe 4 is fixedly installed on the outer surface of one side of the water pump 1. Ear plates 2 are fixedly installed on the upper parts of the outer surfaces on both sides of the water pump 1. A lifting ring 3 is fixedly installed on the outer surface of the upper end of the ear plate 2. A protection structure 6 is fixedly installed at the end of the inlet pipe 5. The protection structure 6 includes a pipe body 16, a hydrophobic hole 17, a ring body 8, a diversion ring 9, an anti-backflow plate 10, an annular limiting cavity 11, a guide rod 12, a slider 13, a sliding hole 14 and a sealing ring 15, and the pipe body 16 is fixedly installed at the end of the inlet pipe 5.

[0026] A filter screen 7 is fixedly installed at the bottom of the inner cavity of the inlet pipe 5, and the filter screen 7 is located below the protection structure 6; the ring body 8 is fixedly installed at the lower end of the inner cavity of the pipe body 16. The diversion ring 9 is fixedly installed on the outer surface of the lower end of the ring body 8, and the diversion ring 9 is located at the bottom of the inner cavity of the pipe body 16; the annular limiting cavity 11 is opened inside the ring body 8. The sliding hole 14 is opened on the outer surface of the upper end of the ring body 8. The hydrophobic hole 17 is opened at the lower end of the inner wall of the ring body 8, and the hydrophobic hole 17 communicates with the bottom of the annular limiting cavity 11. The lower end of the sliding hole 14 communicates with the upper end of the annular limiting cavity 11; the slider 13 is located in the annular limiting cavity 11. The guide rods 12 are fixedly installed on the left and right sides of the outer surface of the lower end of the anti-backflow plate 10, and the guide rods 12 penetrate through the sliding holes 14 and are fixedly connected to the middle of the outer surface of the upper end of the slider 13. The outer wall of the slider 13 is slidably connected with the annular limiting cavity 11, and the outer wall of the guide rod 12 is slidably connected with the sliding hole 14; the sealing ring 15 is fixedly installed on the outer surface of the lower end of the anti-backflow plate 10.

[0027] It should be noted that the present utility model is a water pump with stability and reliability. With the provided protective structure 6, when the water pump 1 operates, liquid enters the water inlet pipe 5, driving the anti-backflow plate 10 to rise, causing the anti-backflow plate 10 to separate from the ring body 8. The anti-backflow plate 10 drives the guide rod 12 to slide along the sliding hole 14, and the sliding hole 14 drives the slider 13 to slide inside the annular limiting cavity 11. The slider 13 plays a limiting role. After the anti-backflow plate 10 separates from the ring body 8, the liquid enters the interior of the water inlet pipe 5. When the water pump 1 stops operating, the external liquid stops flowing into the interior of the water inlet pipe 5, and the liquid inside the water inlet pipe 5 presses on the anti-backflow plate 10. The anti-backflow plate 10 resets to the outer surface of the upper end of the ring body 8, and through the provided sealing ring 15, it plays a sealing role. When the anti-backflow plate 10 reaches the outer surface of the upper end of the ring body 8, the anti-backflow plate 10 can prevent the water inside the water inlet pipe 5 from flowing back, ensuring that the water flow can only enter the water inlet pipe 5 from the water pool and cannot flow back. This helps to ensure that the water inlet pipe 5 is always filled with water, enabling the water pump 1 to start automatically and quickly, improving the reliability and stability of the start. A filter screen 7 is installed at the bottom of the inner cavity of the water inlet pipe 5, which can play a protective role. When water enters the annular limiting cavity 11 through the sliding hole 14, it can be discharged through the hydrophobic hole 17.
