Technical Field

[0001] The utility model belongs to the technical field of circulating pumps, and in particular relates to a seawater circulating pump with adjustable blades. Background Art

[0002] With the increasing abundance and development of marine resources, the demand for seawater utilization is also growing. However, the high salinity and large temperature changes of seawater pose great challenges to seawater utilization equipment. Traditional seawater circulation pumps often ignore the adjustability of blades during the design process, resulting in poor performance under different working conditions. Therefore, in response to this problem, a seawater circulation pump with adjustable blades is proposed to meet the needs of different application scenarios.

[0003] In the design of seawater circulation pump, we must first have a deep understanding of the working principle and structure of the seawater circulation pump, so as to design a seawater circulation pump with adjustable blades. This pump should have a central shaft with adjustable blades installed on the shaft. The angle of the blades can be adjusted according to needs to change the flow and pressure of the seawater circulation pump. Such a design can not only improve the efficiency of the seawater circulation pump, but also adjust the performance of the seawater circulation pump according to actual needs, reduce energy consumption, and achieve environmental protection goals.

[0023] The present invention is further described in detail below in conjunction with the embodiments, but the implementation manner of the present invention is not limited thereto.

[0024] Example 1

[0025] like Figure 1 As shown, a seawater circulation pump with adjustable blades includes a main shaft 1, one end of which is connected to a driving motor 2, and the other end of the main shaft 1 extends into a flow channel 3. A plurality of rotating shafts 4 are rotatably arranged on the main shaft 1 in the flow channel 3, and blades 5 are arranged on the rotating shafts 4.

[0026] In the utility model, the angle of the blade 5 is adjusted to adjust the flow rate and pressure of the seawater circulation pump.

[0027] Example 2

[0028] The difference between this embodiment and embodiment 1 is that: Figure 2 As shown, a first gear 11 is provided on the main shaft 1 in the flow channel 3, and a second gear 41 meshing with the first gear 11 is provided on the rotating shaft 4. The second gear 41 and the first gear 11 rotate to change the angle between the rotating shaft 4 and the main shaft 1, thereby adjusting the angle of the blade 5.

[0029] The angle between the main shaft 1 and the rotating shaft 4 in the flow channel 3 can also be adjusted by other adjustment mechanisms in the prior art, so that the angle between the blade 5 and the main shaft 1 is adjustable.

[0030] The blades 5 are made of stainless steel or aluminum alloy, which improves the adaptability of the circulating pump to the seawater corrosion environment.

[0031] The shape of the blade 5 is a curved surface. The size and angle of the blade 5 are precisely calculated to ensure that the seawater circulation pump works in a high efficiency zone.

[0032] The blade 5 is provided with a wear-resistant coating, which is processed to improve the wear resistance and corrosion resistance of the blade 5.

[0033] The main shaft 1 is connected to the driving motor 2 via a coupling 6 .

[0034] One end of the flow channel 3 is an inlet end 31 , and the other end of the flow channel 3 is an outlet end 32 .

[0035] The outlet 32 ​​is provided with a sensor for detecting the flow rate and pressure of the seawater circulation pump. The sensor is used to detect the flow rate and pressure of the seawater circulation pump, and provides a theoretical basis for adjusting the angle of the blade 5, so that the circulation pump can achieve the required flow rate and pressure.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solution of the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents.
