Embodiment
Below embodiment of the present utility model is described; so that those skilled in the art understand the utility model; but should be clear; the utility model is not limited to the scope of embodiment; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined, these changes are apparent, and all innovation and creation utilizing the utility model to conceive are all at the row of protection in appended claim.
With reference to figure 1, with reference to figure 2 and the stereogram showing the enclosed water pump impeller being convenient to process with reference to figure 3, Fig. 1; Fig. 2 show the blade of enclosed water pump impeller being convenient to process and front shroud weld together after stereogram; Fig. 3 shows the stereogram of the back shroud being convenient to the enclosed water pump impeller processed.
As shown in Figure 1 to Figure 3, this enclosed water pump impeller being convenient to process comprises front shroud 1, blade 2 and back shroud 3; Front shroud 1, blade 2 and back shroud 3 are injection molded all separately; The edge of front shroud 1 and back shroud 3 offers some tapped holes 11 equably; And be fixedly installed togather by bolt 4 between the front shroud 1 that blade 2 welds together and back shroud 3.
Due to structure all very simple of the blade 2 of split, front shroud 1, blade 2 and back shroud 3, injection molding blade 2 out, front shroud 1 and back shroud 3 outer surface are relatively smooth, and follow-up needs are simply polished processing.Carry out polishing and add man-hour, because blade 2, front shroud 1 and each face of back shroud 3 can be seen clearly, polishing processing very quick, shortens the polishing cycle.
The central position of front shroud 1 is provided with first loop configuration integrated with it, the central position of back shroud 3 be provided with one-body molded with it and with the second loop configuration of the first annular respective outer side edges.Front shroud 1 and back shroud 3 can carry out accurate contraposition rapidly by the first loop configuration and the second loop configuration, thus improve the packaging efficiency of enclosed water pump impeller.
The thickness of blade 2 is outwards increased progressively gradually by front shroud 1 center; Add blade 2 and the area of contact of front shroud 1 after arranging like this, increase the stressed of blade 2 root, ensure that the working life of impeller.
Wherein, the first loop configuration is made up of the first annular flange flange 14 and the second annular flange flange 13, forms the first annular slot 12 between the first annular flange flange 14 and the second annular flange flange 13.Second loop configuration forms by the 3rd annular flange flange 33 coordinated with the first annular slot 12 with the 4th annular flange flange 32 that the 3rd annular flange flange 33 forms the second annular slot 31; Second annular flange flange 13 is installed in the second annular slot 31.
First loop configuration and the second loop configuration complement each other to form axle mounting hole; First loop configuration and the second loop configuration adopt said structure, can also ensure the stability be installed together between front shroud 1 and back shroud 3 while can realizing rapid-aligning.
Plastics back-up ring is provided with in first annular slot 12 and the second annular slot 31; When the arranging of plastics back-up ring can avoid front shroud 1 and back shroud 3 to assemble, there is rigid impact in the first loop configuration and the second loop configuration.
The height of the first annular flange flange 14 equals the height of the 4th annular flange flange 32, and the height of the second annular flange flange 13 equals the height of the 3rd annular flange flange 33; The height of the second annular flange flange 13 adds that the thickness of plastics back-up ring equals the height of the first annular flange flange 14.After arranging like this, after guarantee first loop configuration and the second loop configuration fit together, the thickness of the axle mounting hole everywhere between front shroud 1 and back shroud 3 is all equal.
The opposite side central position of back shroud 3 is provided with the axle sleeve 5 with the first annular flange flange 14 equal diameters.Axle sleeve 5 can facilitate the installation of water pump bearing.
Blade 2 is oar shape helically, and the thickness at blade 2 arbitrary cross-section place is all equal; The quantity of blade 2 is four to six, and the angle between blade 2 and front shroud 1 is set to 30 °-60 °; The quantity of blade 2 and the setting of angle increase the water absorption of water pump.
When water pump is for extracting the liquid containing corrosive deposit, impeller is easy to be corroded and affects working life, so preferably blade 2, front shroud 1 and back shroud 3 all adopt cemented carbide to make, and are coated with one deck anticorrosive coat at the outer surface of blade 2, front shroud 1 and back shroud 3.During production, preferred anticorrosive coat is polyurethane antiseptic finishing paint.
Although describe in detail embodiment of the present utility model by reference to the accompanying drawings, should not be construed as the restriction of the protection domain to this patent.In the scope described by claims, the various amendment that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
