Problems solved by technology

Because the graphite material of the static ring body is soft, it is not resistant to the friction of hard and sharp debris, so after the granular material enters, it is easy to damage the end face of the static ring, resulting in seal failure and shortening the service life of the seal.

Embodiment 1

[0026] Such as figure 1 As shown, the seal of the present invention includes a moving ring body 1, a static ring body 2, a moving ring seat cover 6, a static ring seat cover 8, a moving ring sealing ring 7, a spring 3, a spring seat ring 4 and a rubber sealing sleeve 5. The moving ring body 1 is generally made of ceramic material or stainless steel metal material, and the static ring body 2 is generally made of graphite material, which is relatively soft. The moving ring body 1 is set on the moving ring seat cover 6 , and a moving ring sealing ring 7 is arranged between the moving ring body 1 and the moving ring seat cover 6 . The lower surface of the moving ring body 1 is closely matched with the upper surface of the static ring body 2, and three circles of deposition grooves are arranged on the contact surface of the moving ring body 1 and the static ring body 2, and the grooves are opened on the upper surface of the static ring body. On the surface, the annular groove 11 o...

Embodiment 2

[0030] Such as image 3 As shown, the seal of the present invention includes a moving ring body 1, a static ring body 2, a moving ring seat cover 6, a static ring seat cover 9, a moving ring sealing ring 7, a spring 3, a spring seat ring 4 and a rubber sealing sleeve 5. The moving ring body 1 is generally made of ceramic material or stainless steel metal material, and the static ring body 2 is generally made of graphite material, which is relatively soft. The moving ring body 1 is set on the moving ring seat cover 6 , and a moving ring sealing ring 7 is arranged between the moving ring body 1 and the moving ring seat cover 6 . The lower surface of the moving ring body 1 is closely matched with the upper surface of the static ring body 2, and three circles of protruding rings are arranged on the contact surface of the moving ring body 1 and the static ring body 2, and the rings are arranged on the moving ring body on the lower surface of the . The height of the annular ring b...

Abstract

The invention relates to a non-leakage water pump sealing element with multistage sealing function, wherein the invention has better sealing effect, stable property and long application period; and said invention comprises: movable ring, stable ring, movable ring base, stable ring base, movable ring sealing ring, spring, spring base and rubber sealing sleeve; the lower surface of movable ring is matched with upper surface of stable ring, while their contact surface has several rings of deposit grooves or several rings of protruded rings. The invention uses annular structure with different distance, to arrange movable or stable ring into several motion tracks at one end, to realize multi track contact positions at one position, and control the sealing medium to enter into the inner space.

Description

technical field [0001] The invention relates to a non-leakage water pump seal, in particular to an automobile water pump seal. Background technique [0002] Existing automotive water pump seals generally adopt single-stage sealing technology, that is, through a dynamic end face contacting another static end face, combined in one position, the structure generates a single moving track position, preventing the medium from entering another area from one area, This single position application isolation method is called single-stage sealing technology. [0003] However, the end face of the moving ring using single-stage sealing technology rubs along the end face of the static ring. Due to the influence of frequent and strong changes in the rotational speed and the automatic adjustment of the adsorption force of the moving and static ring under the action of spring tension, the sealing end face fluctuates, and the balance force is poor. Uniform, the stability is reduced. In actu...
