Description

Technical Field

[0001] This utility model relates to the field of submersible pump impeller technology, and in particular to a corrosion-resistant submersible pump impeller. Background Technology

[0002] Impeller-type submersible pumps are easy to use; they can be placed directly into the water. The impeller's rotation is driven by a pump shaft, which is in contact with the water. Therefore, a stainless steel pump shaft can be used to improve corrosion resistance and wear resistance.

[0003] Impellers can be made of plastic or stainless steel. Plastic impellers have good corrosion resistance, but their structural strength is low, making them prone to deformation or damage, requiring frequent replacements, which is cumbersome. Stainless steel impellers are expensive and heavy, increasing the energy consumption of the submersible pump, and their corrosion resistance is not as good as that of plastic impellers, requiring improvement.

[0018] The following is combined Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0019] like Figure 1 and Figure 2 The corrosion-resistant submersible pump impeller shown includes: a core disk 9, a plastic wheel disk 1, a stiffening plate 8, and plastic blades 2. The plastic wheel disk 1 has an upwardly extending first reinforcing ring 3 in the middle, which increases the thickness of the middle part of the plastic wheel disk 1.

[0020] In this embodiment, a second reinforcing ring 6 extending downwards is provided in the middle of the plastic disc 1, further increasing the thickness of the middle part of the plastic disc 1. The first reinforcing ring 3 is provided with a mounting hole 4 that penetrates the plastic disc 1 and extends to the bottom of the second reinforcing ring 6, facilitating connection with the pump shaft of the submersible pump to drive the rotation of the plastic disc 1.

[0021] In addition, such as Figure 1 As shown, a keyway 5 is provided in the mounting hole 4, which can be used to install a key block. This key block mates with the keyway on the pump shaft to achieve synchronous rotation drive of the pump shaft to the plastic wheel 1, avoiding relative slippage. A water-retaining ring 7 is integrally provided on the bottom surface of the plastic wheel 1 to reduce the problem of water flowing into the back of the plastic wheel 1.

[0022] The plastic blades 2 are placed on the top of the plastic disc 1 and arranged in a ring array on the outside of the first reinforcing ring 3. In this embodiment, the plastic disc 1, the first reinforcing ring 3 and the second reinforcing ring 6 adopt an integrated plastic structure, which can be made of ABS plastic or nylon material, and has good corrosion resistance and wear resistance.

[0023] like Figure 2 As shown, the core disk 9 is pre-embedded in the plastic disc 1. In this embodiment, the core disk 9 is a circular steel disk or a circular aluminum disk, which has high structural strength, low cost, improves the bending resistance of the plastic disc 1, and reduces deformation during use.

[0024] The stiffening plate 8 is pre-embedded in the plastic blade 2, and the bottom of the stiffening plate 8 is connected to the top surface of the core disk 9. In this embodiment, the stiffening plate 8 is made of arc-shaped steel plate or arc-shaped aluminum plate to improve the structural strength of the plastic blade 2 and prevent deformation. The stiffening plate 8 and the core disk 9 are made of the same material to facilitate welding and fixing of the bottom of the stiffening plate 8 to the top surface of the core disk 9.

[0025] like Figure 2 As shown, the core disk 9 is provided with first injection holes 12 at intervals, and the plastic wheel disk 1 is provided with a first plastic filler 13 extending into the first injection holes 12, which strengthens the connection between the core disk 9 and the plastic wheel disk 1, resulting in high structural stability, extended service life, reduced maintenance frequency, and thus reduced use and maintenance costs.

[0026] A second injection hole 10 is provided at intervals in the stiffening plate 8, and a second plastic filler 11 is provided in the plastic blade 2 extending into the second injection hole 10, which strengthens the connection between the plastic blade 2 and the stiffening plate 8, so that they can work together to exert force when subjected to force, resist deformation, and reduce breakage problems.

[0027] During the production process, the reinforcing plate 8 is welded to the core plate 9 and placed into the mold. Then, the plastic wheel 1 and the plastic blade 2 are integrally injection molded, which can realize the filling of the first injection hole 12 and the second injection hole 10 by the molten plastic, resulting in high production efficiency.
