Description

Technical Field

[0001] The utility model relates to the technical field of water diversion pumps, in particular to a water diversion pump with a self-priming device. Background Art

[0002] Water is an indispensable substance in people's lives. With the rapid advancement of urbanization, people's requirements for improving water quality are getting higher and higher. It has become a trend to adopt fast and efficient water treatment methods to improve water quality. In some water treatment systems, it is necessary to take water from a low water level source. Self-priming pumps are widely used here. Self-priming pumps are self-priming centrifugal pumps with the advantages of compact structure, easy operation, stable operation, easy maintenance, high efficiency, long life and strong self-priming ability. There is no need to install a bottom valve in the pipeline. Before working, it is only necessary to ensure that a certain amount of lead liquid is stored in the pump body. The working principle of the self-priming pump is to fill the pump casing with water before starting the water pump or store water as the lead liquid. After starting, the impeller rotates at high speed to make the lead liquid in the impeller groove flow to the volute. At this time, a vacuum is formed at the inlet to open the water inlet check valve, and the air and water in the suction pipe enter the pump and reach the outer edge through the impeller groove for output.

[0003] When starting an existing water diversion pump, it is usually necessary to fill the pump casing with water or use water as a diversion liquid so that the water diversion pump can discharge the liquid outward. However, its operation is relatively complicated and cumbersome, and the existing water diversion pump sometimes needs to start and stop. Therefore, frequent water filling and diversion consumes a lot of manpower and material resources, greatly reducing work progress. Utility Model Content

[0026] Reference Figure 1 - Figure 3 , which is an embodiment of the present utility model, provides a water pump with a self-priming device, including a main body support unit 100 and a self-priming water unit 200.

[0027] The main support unit 100 includes a load-bearing plate 101 and a base 102 fixedly connected to the upper surface of the load-bearing plate 101.

[0028] The self-suction water unit 200 includes a water tank 201 fixedly connected to the upper surface of the connecting plate 104 and a self-suction box 213 fixedly connected to the upper surface of the support plate 103, wherein one side of the self-suction box 213 is fixedly connected to a pipeline, one side of the water tank 201 is snap-connected to a dredging door 202, the water tank 201 and the self-suction box 213 are fixedly connected through a connecting pipe 203 and a connecting pipe 204, the upper surface of the self-suction box 213 is fixedly connected to an air guide pipe 206, the upper surface of the air guide pipe 206 is fixedly connected to the air suction box 205, and the electric telescopic rod 206 is fixedly connected to the self-suction box 213. 08, the lower surface of the electric telescopic rod 208 is fixedly connected to the sealing plate 210. When the sealing plate 210 and the rubber plate 209 leave the connecting pipe 203, the sealing plate 210 moves upward, resulting in a decrease in the pressure in the lower surface area of ​​the sealing plate 210, causing the liquid to quickly flow into the self-priming box 213. The outer surface of the sealing plate 210 is slidably connected to the inner surface of the self-priming box 213. The self-priming box 213 is fixedly connected with a sealing column 215. One end of the sealing column 215 passes through one side of the sealing plate 210. One side of the sealing plate 210 is fixedly connected to the rubber plate 209.

The sealing plate 210 moves upward to gradually approach the pipe on one side of the self-priming box 213, and then the liquid is discharged outward. At the same time, due to the limited height of the sealing rod, when the sealing plate 210 continues to move upward, the liquid will quickly fill the entire self-priming box 213, thereby causing the floating plate 214 to move upward. Movement is performed to make the plug 219 contact with the air guide pipe 206, thereby keeping the pressure in the self-priming box 213 stable, thereby avoiding repeated water filling operations and further improving the efficiency of the equipment.

The fan 218 is used to drive the air inside the self-priming box 213 to flow to the outside, and one side of the suction box 205 is fixedly connected to the outlet pipe 211.

[0029] When the device is working normally, the water storage tank 201 is used to store external water, and the electric telescopic rod 208 is used to drive the sealing plate 210 to slowly move toward the side of the air outlet pipe 211, and at the same time, the fan 218 is used to drive the air inside the self-priming box 213 to flow to the outside. When the sealing plate 210 and the rubber plate 209 leave the connecting pipe 203, the sealing plate 210 moves upward, resulting in a decrease in the pressure in the lower surface area of ​​the sealing plate 210, causing the liquid to quickly flow into the self-priming box 213, and then the sealing plate 210 is used to move upward, so that the liquid level gradually approaches the pipe on one side of the self-priming box 213, and then the liquid is discharged outward. At the same time, due to the limited height of the sealing rod, when the sealing plate 210 continues to move upward, the liquid will quickly fill the entire self-priming box 213, and then the floating plate 214 will move upward, so that the plug 219 will contact the air guide pipe 206, and then the pressure in the self-priming box 213 will remain stable, thereby avoiding repeated water filling operations and further improving the use efficiency of the equipment.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention.
