Description

Technical Field

[0001] The invention relates to the technical field of fluid conveying equipment, and in particular to an impeller pump with switchable dual-way water outlets. Background Art

[0002] Impeller pumps are commonly used fluid conveying equipment in modern life because of their good head. Impeller pumps are used in environments where their water inlet is lower than the source water level. Impeller pumps generally have an inlet and an outlet, and a pumping chamber inside. The pumping chamber has an impeller. The output shaft of the drive motor drives the impeller to rotate, pumping the liquid from the pumping chamber to the outlet, and then transporting it to other equipment or pipelines. When it is necessary to transport fluids to different waterways or equipment, it is necessary to add multiple waterway switching valves to the waterway at the outlet to transport fluids to different waterways or equipment. This requires the addition of additional valves, making the pipeline more complicated and the cost of use higher. Summary of the invention

[0024] Example

[0025] A dual-outlet switchable impeller pump includes a pump head body 06, which is provided with a water inlet 10, wherein a first water outlet waterway and a second water outlet waterway connected to the water inlet 10 are provided inside the pump head body 06, and further includes a water control component for switching the first water outlet waterway and the second water outlet waterway to opposite on and off states under the action of the outlet water pressure.

[0026] In this embodiment, Figure 1 and Figure 2As shown, a first water outlet waterway and a second water outlet waterway connected to the water inlet 10 are provided in the pump head body 06. The first water outlet waterway and the second water outlet waterway are connected to different equipment or waterways. When the pump head body 06 is working, under the action of the outlet water pressure, the water control component switches the first water outlet waterway and the second water outlet waterway to be in opposite on and off states, that is, when the first water outlet waterway is connected, the second water outlet waterway is disconnected, and when the first water outlet waterway is disconnected, the second water outlet waterway is connected. When it is necessary to pump water to different equipment or waterways, it can be achieved by switching the water control component, and there is no need to add an additional waterway switching valve on the water outlet waterway, which optimizes the waterway connection structure and reduces the use cost.

[0027] Furthermore, the first water outlet waterway includes a first water outlet channel 16 and a first water outlet 17, and the second water outlet waterway includes a second water outlet channel 20 and a second water outlet 23. Under the action of the internal water pressure of the first water outlet channel 16 and the second water outlet channel 20, the water control component switches the waterway between the first water outlet channel 16 and the first water outlet 17 and the waterway between the second water outlet channel 20 and the second water outlet 23 to opposite on and off states.

[0028] Furthermore, a connecting plate 26 protruding outward is provided on one side of the pump head body 06, and a cover plate 15 is sealed to one side of the connecting plate 26. A water passage cavity 14 connected to the first water outlet waterway and the second water outlet waterway is formed between the cover plate 15 and the connecting plate 26. The water control component is located in the water passage cavity 14 and is movably connected to the connecting plate 26. Under the action of the internal water pressure of the first water outlet channel 16 and the second water outlet channel 20, the water control component rotates and switches the waterway between the first water outlet channel 16 and the first water outlet 17 and the waterway between the second water outlet channel 20 and the second water outlet 23 to be in opposite on and off states.

[0029] Furthermore, when the water pressure in the first water outlet channel 16 is greater than the water pressure in the second water outlet channel 20, the water control component rotates to connect the water path between the first water outlet channel 16 and the first water outlet 17 and blocks the water path between the second water outlet channel 20 and the second water outlet 23; when the water pressure in the first water outlet channel 16 is less than the water pressure in the second water outlet channel 20, the water control component rotates to block the water path between the first water outlet channel 16 and the first water outlet 17 and connect the water path between the second water outlet channel 20 and the second water outlet 23.

[0030] Furthermore, the water control component includes a water sealing plate 12, and a rotating shaft 11 is provided on both sides of the middle part of the water sealing plate 12. The water sealing plate 12 is provided with a first sealing gasket 19, a second sealing gasket 18, a third sealing gasket 22, and a fourth sealing gasket 21 corresponding to the first water outlet 17, the first water outlet channel 16, the second water outlet channel 20, and the second water outlet 23. The water sealing plate 12 is in an obtuse V shape, and the rotating shaft 11 is located in the rotating cavity 02 between the connecting plate 26 and the cover plate 15, and the rotating shaft 11 and the cover plate 15 and the connecting plate 26 can rotate relative to each other.

[0031] Specifically, a U-shaped connecting plate 26 is integrally formed on the right side of the pump head, and the connecting opening faces right. The cover plate 15 is adaptably connected to the connecting plate 26. The cover plate 15 is a door-shaped structure. The left end of the cover plate 15 is inserted into the U-shaped cavity of the connecting plate 26. A rotating cavity 02 adapted to the rotating shaft 11 can be formed between the left end of the cover plate 15 and the connecting plate 26. The rotating shaft 11 is rotatably arranged in the rotating cavity 02. Since the water sealing plate 12 is in an obtuse V-shape, under the action of the internal water pressure of the first water outlet channel 16 and the second water outlet channel 20, the water sealing plate 12 can rotate clockwise or counterclockwise with the rotating shaft 11 as the axis, thereby switching the first water outlet waterway and the second water outlet waterway to opposite water flow and water cut-off states.

[0032] Furthermore, when the water pressure in the first water outlet channel 16 is greater than the water pressure in the second water outlet channel 20, the water sealing plate 12 rotates clockwise, the water path between the first water outlet channel 16 and the first water outlet 17 is connected, and the water path between the second water outlet channel 20 and the second water outlet 23 is blocked by the third sealing gasket 22 and the fourth sealing gasket 21. When the water pressure in the first water outlet channel 16 is less than the water pressure in the second water outlet channel 20, the water sealing plate 12 rotates counterclockwise, the water path between the first water outlet 17 and the first water outlet channel 16 is blocked by the first sealing gasket 19 and the second sealing gasket 18, and the water path between the second water outlet channel 20 and the second water outlet 23 is connected.

[0033] Specifically, the first sealing gasket 19, the second sealing gasket 18, the third sealing gasket 22, and the fourth sealing gasket 21 are all fixed on the water sealing plate 12. The first sealing gasket 19 and the second sealing gasket 18 can completely seal the water inlet end of the first water outlet 17 and the water outlet end of the first water outlet channel 16 after the water sealing plate 12 is rotated counterclockwise by a certain angle. The greater the water pressure in the second water outlet channel 20, the better the sealing effect. Similarly, the third sealing gasket 22 and the fourth sealing gasket 21 can completely seal the water outlet end of the second water outlet channel 20 and the water inlet end of the second water outlet 23 after the water sealing plate 12 is rotated clockwise by a certain angle. The greater the water pressure in the first water outlet channel 16, the better the sealing effect.

[0034] Furthermore, a first sealing ring 13 is compressed between the connecting plate 26 and the cover plate 15 .

[0035] Furthermore, the pump head body 06 is provided with a water pumping chamber 07 connected with the water inlet 10, the first water outlet waterway and the second water outlet waterway, and a water pumping assembly is provided in the water pumping chamber 07. A base 25 is provided at the bottom of the pump head body 06, and the water pumping chamber 07 is formed between the base 25 and the inner wall of the pump head body 06. The bottom surface of the base 25 is connected to a driving motor 01, and the output shaft 03 of the driving motor 01 passes upward through the base 25 and is connected to the water pumping assembly. The output shaft 03 rotates clockwise or counterclockwise to drive the water pumping assembly to rotate, and the water pumping assembly rotates clockwise or counterclockwise to pump water toward the first water outlet waterway or the second water outlet waterway.

[0036] Furthermore, the water pump assembly includes a rotating seat 08 and blades 24. The rotating seat 08 is connected to the output shaft 03. The impeller is evenly distributed in a ring shape around the rotating seat 08. The top surface of the base 25 is embedded with a second sealing ring 04 located on the outside of the output shaft 03. The output shaft 03 is sleeved with a third sealing ring 09 located above the rotating seat 08.

[0037] Furthermore, a groove is provided on the top surface of the base 25 , and a fourth sealing ring 05 is embedded in the groove. The fourth sealing ring 05 is pressed tightly between the base 25 and the pump head body 06 .

[0038] The water circuit switching principle of the present invention is as follows: the water inlet 10 is lower than the liquid level, the liquid enters the water pump chamber 07 from the water inlet 10, the first water outlet 17 and the second water outlet 23 are connected to different devices or water circuits, when the pump head body 06 is working, when the output shaft 03 of the driving motor 01 rotates clockwise, the rotating seat 08 drives the blades 24 to rotate clockwise, and the water in the water pump chamber 07 is transported to the first water outlet channel 16, the water volume in the first water outlet channel 16 is much larger than the water volume in the second water outlet channel 20, at this time, the water pressure in the first water outlet channel 16 is larger than the water pressure in the second water outlet channel 20, the water pressure in the first water outlet channel 16 pushes the sealing plate 12 to the right, and the sealing plate 1 The rotating shaft 11 rotates clockwise, and the first sealing gasket 19 and the second sealing gasket 18 release the sealing of the water outlet end of the first water outlet channel 16 and the water inlet end of the first water outlet 17. At this time, the water passage chamber 14 connects the waterway between the first water outlet channel 16 and the first water outlet 17, and the water is pumped from the first water outlet 17 to the designated equipment or waterway. After the water sealing plate 12 rotates clockwise at a certain angle, the third sealing gasket 22 and the fourth sealing gasket 21 seal the water outlet end of the second water outlet channel 20 and the water inlet end of the second water outlet 23. In this way, the water sealing plate 12 switches the first water outlet waterway to be connected and the second water outlet waterway to be blocked under the water pressure inside the first water outlet channel 16.

[0039] On the contrary, when the output shaft 03 of the driving motor 01 rotates counterclockwise, the water in the pump water chamber 07 is transported to the second water outlet channel 20. The amount of water in the first water outlet channel 16 is much smaller than the amount of water in the second water outlet channel 20. At this time, the water pressure in the first water outlet channel 16 is smaller than the water pressure in the second water outlet channel 20. The water pressure in the second water outlet channel 20 pushes the water sealing plate 12 to the right. The water sealing plate 12 rotates counterclockwise with the rotating shaft 11 as the axis. The third sealing gasket 22 and the fourth sealing gasket 21 release the seal on the water outlet end of the second water outlet channel 20 and the water inlet end of the second water outlet 23. At this time, the water chamber 1 4 connects the waterway between the second water outlet channel 20 and the second water outlet 23, the first sealing gasket 19 and the second sealing gasket 18 seal the water inlet end of the first water outlet 17 and the water outlet end of the first water outlet channel 16, and water is pumped from the second water outlet 23 to the designated equipment or waterway. After the water sealing plate 12 rotates counterclockwise by a certain angle, the second sealing gasket 18 and the first sealing gasket 19 seal the water outlet end of the first water outlet channel 16 and the water inlet end of the first water outlet 17, so that the water sealing plate 12 switches the first water outlet waterway to be blocked and the second water outlet waterway to be connected under the water pressure inside the second water outlet channel 20. When it is necessary to pump water to different equipment or waterways, it is only necessary to change the water pressure inside the first water outlet channel 16 and the second water outlet channel 20 by rotating the driving motor 01 forward and reversely, and then the water outlet waterway can be switched by rotating the water sealing plate 12, without adding an additional waterway switching valve on the water outlet waterway, thereby optimizing the waterway connection structure and reducing the use cost.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. According to the technical essence of the present invention, within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the present invention.
