Description

Technical Field

[0001] The utility model relates to the technical field of fluid machinery, in particular to a staggered impeller structure. Background Art

[0002] The main function of the impeller is to convert the mechanical energy of the prime mover into the static pressure energy and dynamic pressure energy of the working fluid. In the water pump, the impeller pushes the water into the pipe through the centrifugal force generated by the rotation, thereby realizing the transportation and lifting of water.

[0003] Existing impeller structures, such as an alloy aluminum impeller with a staggered blade distribution structure disclosed in the invention patent with application number 202111221205.9, have a main structure including a base, a column fixedly connected to the middle of the upper end face of the base, main blades and auxiliary blades are arranged on the outside of the column, and the inner cavity of the column is fixedly connected to the rotating shaft through a locking mechanism; when in use, the slope angle of the first inclined surface is degrees and the slope angle of the second inclined surface is degrees, so that the entire device realizes the optimized design of the structure of the main blades and auxiliary blades. The main blades and auxiliary blades are made of aluminum alloy, and the base and column are made of titanium alloy, which improves the impact resistance and reliability of the entire device during operation. After the first gasket, the second gasket, the base and the column are passed through the locking screw and placed on the locking screw, the locking nut can be turned to keep the impeller fixed, ensuring the operational stability of the entire device during use.

[0004] However, in actual use of most existing impellers, increasing the number of blades will increase the loss of liquid due to viscous force, so that the unconstrained liquid will form vortices, which will increase flow resistance and affect hydraulic efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a staggered impeller structure which can not only increase the constraint on the liquid, but also avoid affecting the hydraulic efficiency and improve the hydraulic efficiency.

[0006] The utility model provides a staggered impeller structure, including a connecting mechanism connected to the main shaft of a water pump; and an impeller, which is mounted on the connecting mechanism and guides the water flow; the connecting mechanism is connected to the main shaft of the water pump, and the impeller is mainly driven to rotate through the connecting mechanism, and the impeller guides the water flow, draws in and discharges the water flow.

[0007] Preferably, the impeller includes a lower cover, seven groups of main blades and an upper cover, the lower cover is connected to the connecting mechanism, the seven groups of main blades are evenly distributed and installed on the upper cover, the bottom end of the upper cover is connected to the top end of the seven groups of main blades, and a water inlet is opened on the upper cover; water flows into between the multiple groups of main blades through the water inlet of the upper cover, and a flow channel is formed between two adjacent groups of main blades. The connecting mechanism drives the impeller to rotate, and the water flows out through the flow channel.

[0008] Preferably, fourteen groups of first auxiliary blades are installed on the upper cover, and two groups of first auxiliary blades are distributed at 1 / 3 of the outlet of each flow channel. The height of the first auxiliary blades is 1 mm and the width is 0.8 mm. By setting up multiple groups of first auxiliary blades, the restraining effect on the water flow is enhanced. At the same time, since the number of first auxiliary blades is small and the length is short, it will not actually affect the water efficiency, thereby improving the water efficiency.

[0009] Preferably, a second auxiliary blade is arranged in the middle of the flow channel corresponding to the main blade on the lower cover, and is staggered with the first auxiliary blade with a staggered spacing of 0.5-1mm; by arranging multiple groups of second auxiliary blades correspondingly on the lower cover, and by arranging multiple groups of first auxiliary blades and second auxiliary blades staggered up and down at the 1 / 3 outlet of the impeller, while increasing the liquid constraint, due to the small number and short length of the staggered blades, it will not actually affect the hydraulic efficiency, thereby improving the hydraulic efficiency.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the connecting mechanism is connected to the main shaft of the water pump, the impeller is mainly driven to rotate through the connecting mechanism, and the impeller guides the water flow, draws in and discharges the water flow.
