[0022] Reference Figures 1 to 4A liquid pump adaptable to different applications includes: a pump body 100, a centrifugal impeller 200, and an impeller drive mechanism 300. The pump body 100 is provided with an impeller cavity 110, an outer peripheral cavity 120, an inlet nozzle 130, and an outlet nozzle 140. There are two impeller cavities 110, which are located at opposite ends of the pump body 100 along its length, as shown by double arrow A in the attached figure. The outer peripheral cavity 120 extends along the length of the pump body 100 and surrounds the two impeller cavities 110. The impeller cavities 110 communicate with the outer peripheral cavity 120 at their peripheral sidewalls. Two inlet nozzles 130 are provided and are respectively located at both ends of the pump body 100 along its length. The two inlet nozzles 130 correspond one-to-one with the two impeller cavities 110. Each inlet nozzle 130 has an inlet channel communicating with the center of the corresponding impeller cavity 110. The outer peripheral cavity 120 is located on the inner side of the outer peripheral wall of the pump body 100. The outlet nozzle 140 is located on the outer peripheral surface of the pump body 100 and has an outlet channel communicating with the outer peripheral cavity 120. Two centrifugal impellers 200 are provided, each corresponding one-to-one with the two impeller cavities 110. An impeller drive mechanism 300 is disposed on the pump body 100 and connected to two centrifugal impellers 200.

[0023] The aforementioned liquid pump has impeller chambers 110 and centrifugal impellers 200 at both ends along the length of the pump body 100, and two inlet nozzles 130 are correspondingly provided, thus providing more space on the inlet side for convenient pipe connection operations. Furthermore, by configuring an outer peripheral cavity 120 surrounding the impeller chambers 110, the outlet nozzles 140 can be freely configured at different positions on the outer peripheral surface of the pump body 100, and the number can be configured according to needs. All outlet nozzles 140 receive the pumped liquid through the outer peripheral cavity 120, thus allowing for convenient pipe connection configuration on the outlet side of the liquid pump. In addition, the arrangement of two sets of impeller chambers 110 and centrifugal impellers 200 also enhances the pumping capacity of the liquid pump.

[0024] In this embodiment, at least two outlet nozzles 140 are provided, and the outlet nozzles 140 are arranged circumferentially along the pump body 100 at different positions on the circumferential surface of the pump body 100. By providing multiple outlet nozzles 140, multiple connection points are provided on the outlet side, thereby facilitating connection.

[0025] In this embodiment, the pump body 100 is provided with a liquid outlet 140 on each of its opposite sides along the vertical length direction, which is convenient for occasions where liquid needs to be output from the opposite side.

[0026] It is conceivable that the number and position of the liquid outlet 140 can be reasonably configured according to the actual situation, and are not limited to the above-described implementation method.

[0027] In this embodiment, the impeller drive mechanism 300 is a motor, with motor shafts extending from both ends of the motor, corresponding one-to-one with the two centrifugal impellers 200. The two centrifugal impellers 200 are fixed to their respective motor shafts. Using this structure, the two centrifugal impellers 200 can be driven to rotate simply, facilitating production implementation. Of course, in some embodiments, two motors can be used to drive the two centrifugal impellers 200 separately.

[0028] In this embodiment, each centrifugal impeller 200 is a single-wheel structure. In some embodiments, the centrifugal impeller 200 may also adopt a multi-wheel structure, for example, a large impeller and a small impeller are combined to form the centrifugal impeller 200 of this embodiment.

The two ends of each connecting portion 170 are connected to the inner cylindrical shell 151 and the outer peripheral cylindrical shell 152, respectively, and the connecting portions 170 are arranged circumferentially along the inner cylindrical shell 151. By adopting the above structure, the structural strength of the main shell 150 can be improved.

[0031] In this embodiment, the connecting portion 170 divides the outer peripheral cavity 120 into multiple sub-cavities, which are interconnected. The liquid outlet 140 is correspondingly positioned opposite to each sub-cavity, and the liquid outlet channel of the liquid outlet 140 is directly connected to the corresponding sub-cavity. With the above structure, the liquid flow can be smoothly output.

[0032] In this embodiment, two outlet nozzles 140 are provided, with two separate cavities corresponding to each other. Two impeller cavities 110 correspond to the aforementioned two separate cavities, and each impeller cavity 110 communicates with its corresponding separate cavity through a connecting hole 180 formed in its peripheral sidewall. With this structure, the path from the impeller cavity 110 to the outlet nozzle 140 is short, resulting in smooth output.

[0033] In this embodiment, the connecting portion 170 is provided with a first mounting post 171, which extends along the length of the pump body 100. Screw holes are provided at both ends of the first mounting post 171 along its length. End caps 160 are fitted with inner screws (not shown in the figures) that correspond one-to-one with the screw holes of the first mounting post 171. These inner screws are threaded into the screw holes of the first mounting post 171, locking the end caps 160 to the first mounting post 171. Using this structure, the end caps 160 are securely fixed by the first mounting post 171 on the connecting portion 170.

[0034] In this embodiment, the outer periphery of the outer casing 152 is provided with a plurality of second mounting posts 190 corresponding one-to-one with the first mounting posts 171. The second mounting posts 190 extend along the length direction of the pump body 100, and screw holes are provided at both ends of the second mounting posts 190 along the length direction. The end caps 160 are provided with outer screws (not shown in the figure) that correspond one-to-one with the screw holes of the second mounting posts 190. The outer screws are threaded into the screw holes of the second mounting posts 190 and lock the end caps 160 to the second mounting posts 190. With the above structure, the structure that fixes the inner side of the end caps 160 with the first mounting posts 171 is further fixed to the relatively outer side of the end caps 160 by the second mounting posts 190, making the fixation more secure.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
