Detailed Description
The invention relates to a novel impeller of a peripheral pump. As shown in fig. 1-1 and 2, the main body of the cake-shaped body 1 is provided with a cylindrical coupling protrusion 2 at the center of one side of the cake-shaped body 1, and the height of the coupling protrusion is longer than the thickness of the cake-shaped body 1. A circular hole 3 with a plain section is penetrated in the coupling bulge 2, and the circular hole 3 with the plain section and the coupling bulge 2 have the same axle center and are used for connecting a rotating shaft of the vortex pump. The coupling bulge 2 is used for increasing the length of connection with the rotating shaft, and improves the coaxiality and reliability between spare and accessory parts.
Two identical circular grooves 4 are arranged on two sides of the cake-shaped body 1 and are used for shortening the matching space of the impeller and other spare and accessory parts. Two balance through holes 5 are arranged on the circular groove 4, the balance through holes 5 are centrosymmetric and used for balancing fluid pressure difference generated by the two sides of the impeller when the impeller works, so that the impeller always keeps an upright state when working and is not easy to deflect.
The same overflowing grooves 6 which are arc-shaped and arranged at equal intervals are arranged at the edges of the two sides of the cake-shaped body 1, the overflowing grooves 6 at the two sides are arranged at the two sides of the edge of the cake-shaped body 1 in a wave-shaped manner in a staggered manner, and the end surface lines of the edges of the overflowing grooves 6 are parabolic. The volume of the flow-through groove 6 largely determines the flow rate of the pump, and in the present invention, the thickness of the top notch of the flow-through groove 6 exceeds the thickness center line of the cake 1, as shown in fig. 2.
The difference between the structure and the traditional vortex pump impeller can be clearly seen. In the figure 1-2, the two side edges of the cake-shaped body of the traditional vortex pump impeller are provided with the overflowing grooves with flat plate type structures, the overflowing grooves on the two sides are arranged in an equal way, no staggering is formed between the overflowing grooves, and the notch of each overflowing groove does not exceed the thickness center line of the cake-shaped body 1. The invention is different from the prior art, the overflow grooves 6 ensure the strength of the edge of the cake-shaped body 1, and the thickness of the notches at the top parts of the overflow grooves 6 at the two sides of the cake-shaped body 1 exceeds the thickness central line of the cake-shaped body 1, so that the effective space of the edge of the cake-shaped body 1 is utilized to the greatest extent; secondly, because the notches at the top parts of the overflowing grooves 6 at the two sides of the cake-shaped body 1 are arranged in a staggered manner, fluid media carried by the overflowing grooves 6 at the two sides generate intersection, the pressure difference generated by the two sides of the impeller in a high-speed rotating state of the impeller is further balanced, the impact force and overflowing abrasion on the inner wall of the pump body are reduced, the efficiency is improved, and meanwhile, the noise generated by the impact of the fluid on the inside of the pump body is reduced.
The working principle of the invention is briefly described as follows:
when the fluid medium enters the overflow groove 6 of the impeller, the impeller rotates to drive the fluid medium in the overflow groove 6 to rotate at a high speed, and simultaneously, the fluid medium at the edge of the impeller is driven to rotate in the same direction to form a vortex, and finally, the pressurization process of the fluid medium is completed, so that the flow of the pump is determined to a large extent by the volume capacity of the overflow groove 6.
