Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-2 This utility model provides a technical solution: a ceramic chemical pump, which includes:

[0031] Pump body 1, wherein an impeller cavity 2 is provided inside the pump body 1, and an inlet pipe 3 and an outlet pipe 4 are provided on the impeller cavity 2;

[0032] Pump cover 5, the pump cover 5 is detachably connected to one end of the pump body 1, and a corrosion-resistant rubber gasket 6 is provided between the pump cover 5 and the pump body 1;

[0033] Impeller 7 is connected to pump shaft 8 and is located in impeller cavity 2. Pump shaft 8 passes through pump cover 5 and is connected to output shaft of motor 9. A sealing component 10 is provided between pump cover 5 and impeller 7 and passes through pump shaft 8.

[0034] Both the inlet pipe 3 and the outlet pipe 4 are equipped with dustproof nets. These nets prevent external dust and impurities from entering the pump body, thus extending its service life, reducing maintenance and replacement costs, and facilitating the connection of external water pipes.

[0035] Both the inlet pipe 3 and the outlet pipe 4 are equipped with connecting flanges 11. This facilitates the connection of the inlet and outlet pipes to the pipeline and improves the stability of the connection.

[0036] The surface of the impeller cavity is provided with a high-temperature sintered silicon carbide ceramic layer.

[0037] The pump body adopts a modular design. The surface of the impeller cavity inside the pump body has a high-temperature sintered silicon carbide ceramic layer, which has excellent wear and corrosion resistance and a service life 3-10 times that of alloys and stainless steel. The material of the pump body that does not come into contact with the medium is a high-strength metal material, which has a pressure-bearing protection function. Similarly, a high-temperature sintered silicon carbide ceramic layer can also be set on the surface of the pump cover and impeller that come into contact with the medium to improve the wear and corrosion resistance of the pump cover and impeller.

[0038] The pump cover 5 is provided with bolt holes, and bolts 12 are installed in the bolt holes. The bolts 12 pass through the corrosion-resistant rubber gasket 6 and are connected to the pump body 1. This makes the corrosion-resistant rubber gasket more stable and secure.

[0039] The sealing component 10 is a mechanical seal.

[0040] A base 13 is provided at the bottom of the pump body 1, and the motor 9 is connected to the base 13. The motor 9 is located at one end of the pump body 1. The base ensures the stability and integrity of the pump body during operation.

[0041] Working Principle: A corrosion-resistant rubber gasket is added to the mating area between the pump cover and the pump body, providing a seal and preventing the connecting bolts from breaking due to corrosion. The corrosion-resistant rubber gasket itself is elastic, effectively damping and buffering vibrations generated by the pump body during operation, ensuring a stable connection between the pump cover and the pump body and guaranteeing the smooth operation of the entire pump unit. Dustproof screens are installed on the inlet and outlet pipes to effectively prevent external dust and impurities from entering the pump body, ensuring the cleanliness and safety of the pump during operation.
