Novel ceramic gasket

Abstract

The utility model relates to the technical field of gaskets, in particular to a novel ceramic gasket, which is characterized in that a groove on a ceramic gasket main body is sleeved on a shaft of an electronic water pump, so that when cooling liquid in the water pump is less, the transfer of heat generated by rotor friction to a plastic volute is reduced, and the service life of the ceramic gasket is prolonged. The ceramic gasket main body is mounted on the shaft of the electronic water pump, so that the machining precision of a volute triangular rib part mold is conveniently reduced, and the practicability of the novel ceramic gasket is improved; comprising a ceramic gasket body. A groove is formed in the middle of the ceramic gasket body.

Description

Technical Field

[0001] This utility model relates to the technical field of gaskets, and in particular to a novel ceramic gasket. Background Technology

[0002] Electronic water pumps, such as the electronic water pump disclosed in utility model patent CN210152986U and the electronic water pump and its thermal management system disclosed in utility model patent CN216741712U, have a water pump impeller that rotates at high speed around the pump shaft during operation. Usually, a gasket is placed between the water pump impeller and the volute to prevent the upward force of the impeller from wearing down the plastic volute.

[0003] However, existing gaskets have been found to have drawbacks during use. When the coolant level in the water pump is low, the heat generated by rotor friction is directly transferred to the plastic volute through the shaft, causing deformation and damage to the volute. Furthermore, they are inconvenient to install, resulting in poor practicality. Therefore, there is an urgent need for a new type of ceramic gasket to improve these problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a novel ceramic gasket in which the groove on the ceramic gasket body is fitted onto the shaft of an electronic water pump. When the coolant in the water pump is low, the heat generated by rotor friction is reduced from being transferred to the plastic volute. Furthermore, by mounting the ceramic gasket body onto the shaft of the electronic water pump, the machining accuracy of the mold for the triangular rib part of the volute is reduced, thereby improving the practicality of the new ceramic gasket.

[0005] This utility model discloses a novel ceramic gasket, comprising a ceramic gasket body; a groove is provided in the middle of the ceramic gasket body;

[0006] The groove on the ceramic gasket body is fitted onto the shaft of the electric water pump. When the coolant in the water pump is low, the heat generated by rotor friction is reduced and transferred to the plastic volute. Furthermore, by mounting the ceramic gasket body on the shaft of the electric water pump, the machining precision of the mold for the triangular rib part of the volute can be reduced, thereby improving the practicality of the new ceramic gasket.

[0007] Preferably, the groove is D-shaped; this facilitates the ceramic gasket body to be fitted onto one end of the electronic water pump shaft, thereby improving the practicality of the new ceramic gasket.

[0008] Preferably, the outer edges at both ends of the ceramic gasket body are chamfered.

[0009] Preferably, the ceramic gasket body is solid except for the groove in the middle.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the groove on the ceramic gasket body is fitted onto the shaft of the electronic water pump, which reduces the transfer of heat generated by rotor friction to the plastic volute when the coolant in the water pump is low. Furthermore, by installing the ceramic gasket body on the shaft of the electronic water pump, it is convenient to reduce the machining accuracy of the mold of the triangular rib part of the volute, thereby improving the practicality of the new ceramic gasket.
