Problems solved by technology
[0003] When the existing water pump seal assembly seals the water pump shaft, it is easy to cause unstable connection of the seal assembly due to the long-term sealing of the water pump shaft, which will cause the seal assembly to fall off and lose the sealing effect. In the process, it is necessary to use adhesives to connect the sealing components. During the connection, the staff needs to stick the two ends of the sealing components together by hand. sealing effect

Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] see Figure 1-4 As shown, a sealing assembly for a water pump shaft includes a water pump shaft 1 and a bearing moving ring 11 sleeved on the top surface of the water pump shaft 1. The outer side of the bearing moving ring 11 is fixedly and slidably installed with a bearing static ring 10. One side of the static bearing ring 10 on the surface of the water pump shaft 1 is sleeved with an integral seal 4, and the surface of one side of the integral seal 4...

The invention discloses a sealing assembly for a water pump rotating shaft. The sealing assembly comprises a water pump shaft rod, a dirt preventing sheet, a dustproof lip, a sealing part whole, a skeleton, a spring ring, a sealing bonding layer, a spring ditch, a lubricating grease layer, a bearing static ring, a bearing moving ring, a first connecting lip sheet, a second connecting lip sheet, aconnecting hole and a fixing plug. According to the sealing assembly, the first connecting lip sheet and the second connecting lip sheet are arranged at the connecting ends of the sealing assembly, bymeans of the connecting hole and the fixing plug between the first connecting lip sheet and the second connecting lip sheet, the two ends of the sealing assembly are connected, in the bonding processof the installing process of the sealing assembly, the situation that dry staff bind the two ends of the sealing assembly with the hands is avoided, moreover, it is ensured that in the using process,the two ends of the sealing assembly are connected more stably, and debonding of connection of the sealing assembly due to long-term vibration and rotation is prevented.
Description
technical field [0001] The invention relates to a seal assembly, in particular to a seal assembly for a water pump shaft, and belongs to the technical field of seal assembly applications. Background technique [0002] A mechanical seal refers to a device that prevents fluid leakage and is composed of at least one pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal to prevent fluid leakage. Mechanism and auxiliary seals are metal bellows mechanical seals, which we call metal bellows seals. In light-duty seals, rubber bellows are used as auxiliary seals. Rubber bellows have limited elasticity, and generally need to be supplemented by springs to meet the load. elastic. [0003] When the existing water pump seal assembly is used to seal the water pump shaft, it is easy to cause unstable connection of the seal assembly due to th...
