Description
Technical Field
The utility model relates to the technical field of circulating pumps, in particular to a novel efficient air conditioner circulating pump.
Background
The existing pipeline circulating pump in China generally has the problems of aging of a mould, low water pump efficiency and large use energy consumption. How to design a novel water pump with high efficiency, energy conservation and reliable use aiming at the existing use working condition is a problem which needs to be solved urgently at present.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a circulating pump which fully adopts a large-flow design concept, enables an integral series water pump to be small in size, high in efficiency and low in energy consumption, and effectively realizes a high mountain cavitation phenomenon.
In order to achieve the purpose, the utility model provides a novel high-efficiency air-conditioning circulating pump which comprises a pump body and an impeller, wherein the pump body is provided with a water suction port and a water outlet, the impeller is arranged in the pump body, the impeller is arranged right opposite to the water suction port, and the water outlet is arranged in the centrifugal direction in which the impeller rotates to generate centrifugal force; and the inlet side line of the blade extends 5-15mm from the coaxial position of the water outlet to the direction of the water suction port.
Further, the inlet angle beta 1 of the impeller is 3-10 degrees.
Further, the outlet angle beta 2 of the blades of the impeller is 25-38 °
Further, the outlet width of the impeller is 1.05-1.2 times of the outlet width of the traditional theoretical impeller.
Compared with the prior art, the utility model has the advantages that: the utility model fully considers the use characteristics of an air conditioner circulating pump, considers that the inlet of a closed circulating system pump has larger pressure, and has obvious effect on improving the cavitation allowance of the water pump, so the water pump adopts the large-flow design concept, and the whole series of water pumps have smaller volume, high efficiency and low energy consumption. Meanwhile, the water pump runs in a large-flow high-efficiency area, so that the water pump can adopt a pipeline with a lower specification at the same flow rate (compared with the traditional circulating pump), and the purchasing, pipeline building and running cost of the whole equipment and the like of a user can be remarkably reduced.

fig. 2 is a schematic structural diagram of an impeller in the embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be further described below.
As shown in fig. 1, the utility model provides a novel high-efficiency air-conditioning circulating pump, which comprises a pump body 1 and an impeller 2, wherein the pump body is provided with a water suction port 3 and a water outlet 4, the impeller 2 is arranged in the pump body 1, the impeller 2 is arranged right opposite to the water suction port 3, and the water outlet 4 is arranged in the centrifugal direction in which the impeller 2 rotates to generate centrifugal force; the inlet side line 5 of the blade extends 5-15mm from the coaxial position 6 of the water outlet to the water suction port direction, and the side wall of the water suction port 3 is thinned as much as possible, so that the length of the flow passage is increased, the relative speed diffusion is reduced, the cavitation resistance is improved, and the hydraulic loss is reduced.
In the present embodiment, as shown in fig. 2, the inlet angle β 1 of the impeller 2 is 3 ° to 10 °, thereby reducing the flow passage diffusion between the adjacent blades.
In the present embodiment, as shown in fig. 2, the blade exit angle β 2 of the impeller 2 is 25 ° to 38 °, thereby reducing the outer diameter of the impeller and thus reducing the disk friction loss.
In the embodiment, the outlet width of the impeller 2 is 1.05-1.2 times of the outlet width of the traditional theoretical impeller, so that the absolute speed of the outlet of the impeller is reduced, and the hydraulic loss of the pumping chamber is reduced.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
