Description

technical field [0001] The invention relates to a seal assembly structure, in particular to a water pump seal assembly structure used in the automotive field. Background technique [0002] At present, the connection between the rubber seal sleeve and the static ring body used in the structure of the automobile water pump seal in China, the domestic seal assembly still uses the glue bonding technology, which has low production efficiency and poor manufacturability. The phenomenon of manual work is serious, and it is limited to the nature of the glue to be bonded. In actual use, it is easily affected by environmental conditions. Glue aging, degumming, and peeling occur at the joint of the glue layer. The long-term sealing cycle is uncertain, and it is difficult to be suitable for automation. Process requirements for high-efficiency production on the assembly line. Although the utility model patent ZL 200620126131.5 announced by the applicant on November 28, 2007 proposed a no...

Problems solved by technology

[0003] The main structure of the traditional seal assembly adopts the spring thrust to compress the end face contact seal between the moving ring body and the static ring body. There are three structural forms, but it is difficult to get a perfect combination of these three types of springs while combining the compensation force and the compensation amplitude.

Therefore, the thrust of the spring in the dynamic seal assembly presses the contact seal between the two ends of the dynamic ring body and the static ring body. Under the fluctuation of the peak value of rotation, the compensation force formed by the balance force difference of the spring has an impact on the seals on both ends of the medium. Medium impurities easily invade the end face and directly damage the end face, thus causing the seal failure phenomenon caused by the end face penetrating the medium leakage. In addition, when the rotation peak frequency changes greatly, a kind of vibration frequency generated on the sealing end face is easy to cause the sealing end face to be not tight. phenomenon, and when the vibrating force and the balance force conflict with each other, a twisting and destructive force is formed

[0004] In addition, the traditional structural design of the rubber sealing sleeve in the seal assembly structure has the characteristics of compression force along with the action of the spring. Since the compression force and the spring are mixed to form a mixed elastic value, the stability of the initial value sometimes affects the initial value of the seal. The normal elastic value is exerted during work, so the stability of the elastic value is also an important combination element for the collaborative sealing requirements of the seal assembly

[0005] Therefore, it is necessary to provide solutions to the above problems and apply new technologies to solve the cooperative sealing problem of the seal assembly structure
