Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ceramic gaskets, in particular to a ceramic gasket for preventing a high-power water pump from cracking. Background Art
[0002] In electronic water pumps, such as the one disclosed in the utility model patent with publication number CN212337704U, which has a protective structure for the impeller bearing in an electronic water pump, and the one disclosed in the utility model patent with publication number CN210152986U, the impeller of the water pump rotates at high speed around the pump shaft. Usually, a wear-resistant ceramic gasket is placed between the impeller and the volute to prevent the upward force of the impeller from wearing away the plastic volute. In the design of low-power water pumps, the ceramic gasket and the shaft each have a limiting flat position to prevent the impeller from rotating with the ceramic gasket, such as Figure 5 shown.
[0003] However, during use, it was found that the above design is not suitable for high-power water pumps. When the water pump power increases, the impeller diameter becomes larger, and the motor torque increases, the friction force during the rotation of the impeller drives the ceramic gasket to rotate together, which increases sharply. As a result, the ceramic gasket collides with the shaft instantly when the impeller starts to accelerate, causing it to crack, resulting in poor practicality. Therefore, there is an urgent need for a high-power water pump anti-cracking ceramic gasket to improve the above problem. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a ceramic gasket body with a regular hexagonal hole that is sleeved on the electronic water pump shaft. When the impeller of the electronic water pump rotates, the six faces in the hole of the ceramic gasket body simultaneously hit the electronic water pump shaft to be subjected to force, which is beneficial to distributing the force per unit area and reducing the risk of damage to the ceramic gasket body, thereby improving the practicality and service life of the ceramic gasket for preventing cracking of high-power water pumps.
[0005] The utility model discloses a ceramic gasket for preventing cracking of a high-power water pump, comprising a ceramic gasket body; a hole is opened in the middle of the ceramic gasket body, and the hole is a regular hexagon;
[0006] The regular hexagonal hole of the ceramic gasket body is put on the electronic water pump shaft. When the impeller of the electronic water pump rotates, the six faces in the hole of the ceramic gasket body hit the electronic water pump shaft at the same time, which is beneficial to distribute the force per unit area and reduce the risk of damage to the ceramic gasket body, thereby improving the practicality and service life of the ceramic gasket that prevents cracking of high-power water pumps.
[0007] Preferably, each side of the regular hexagonal hole is 7 mm in length.
[0008] Preferably, the hole in the middle of the ceramic gasket body can also be plum blossom-shaped; when the impeller of the electronic water pump rotates, the plum blossom-shaped hole distributes the force per unit area, reducing the risk of damage to the ceramic gasket body, thereby improving the practicality and service life of the anti-cracking ceramic gasket of the high-power water pump.
[0009] Preferably, the corners in the plum blossom-shaped hole are all rounded.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] 1. The polygonal and plum blossom-shaped ceramic gasket structure effectively reduces the stress on the ceramic gasket, thereby reducing the risk of ceramic breakage;
[0012] 2. It is very effective on high-power water pumps, but it can also be applied to low-power water pumps. Although the force is not large, we can reduce the thickness of the gasket by using this structure to achieve the effect of cost reduction;
[0013] 3. The process is simple, only mold forming is required, no special processing is required. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.
[0021] Example 1
[0022] like Figures 1 to 5As shown, a ceramic gasket for preventing cracking of a high-power water pump includes a ceramic gasket body 1; a hole 3 is opened in the middle of the ceramic gasket body 1, and the hole 3 is a regular hexagon; each side of the regular hexagonal hole 3 is 7 mm long;
[0023] The electronic water pump shaft 2 is provided with a limiting structure, and the limiting structure is also a hexagonal structure, and each side length of the regular hexagonal structure is also 7 mm;
[0024] The hole 3 of the ceramic gasket body 1 is put on the electronic water pump shaft 2. When the impeller of the electronic water pump rotates, the six faces in the hole 3 of the ceramic gasket body 1 hit the electronic water pump shaft 2 at the same time, which is beneficial to distribute the force per unit area and reduce the risk of damage to the ceramic gasket body 1, thereby improving the practicality and service life of the ceramic gasket for preventing high-power water pumps from cracking. The hexagon can also play a good anti-rotation effect, which can not only effectively prevent rotation, but also reduce force and processing costs. When there are more contact surfaces, such as octagons or more, the processing cost increases first. At the same time, the more polygonal sides there are, the more they tend to be circular, and the worse the anti-rotation effect is. When it is made into a square or a triangle, although the processing cost is reduced, the force is still large and there is a risk of damage.
[0025] Example 2
[0026] A high-power water pump anti-cracking ceramic gasket includes a ceramic gasket body 1; a hole 3 is opened in the middle of the ceramic gasket body 1, and the hole 3 is a regular hexagon; each side of the regular hexagonal hole 3 is 7 mm long;
[0027] The hole 3 in the middle of the ceramic gasket body 1 may also be in the shape of a plum blossom; the corners of the plum blossom-shaped hole 3 are all rounded;
[0028] The electronic water pump shaft 2 is provided with a limiting structure, and the limiting structure is also a plum blossom structure, and the corners of the plum blossom structure are also rounded;
[0029] When the impeller of the electronic water pump rotates, the plum blossom-shaped holes 3 distribute the force per unit area, reducing the risk of damage to the ceramic gasket body 1, thereby improving the practicality and service life of the anti-cracking ceramic gasket for high-power water pumps.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
