Embodiment 1
[0025] Refer to attached figure 1 :
[0026] figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. The axial vibration-resistant mechanical seal device includes a static ring seat 1, a static ring 2, a moving ring 3, a moving ring seat 4, a spring vibrator system and other related parts. The spring vibrator system includes a first spring seat 6, an elastic element 7. Screw 8, second spring seat 9, vibrator 10.
[0027] The axial vibration-resistant mechanical seal device includes a seal pair formed by the contact between the moving ring 3 and the static ring 2. The vertical direction of the sealing end faces of the moving ring 3 and the static ring 2 is defined as the axial direction. The moving ring 3 is set in the moving ring seat 4, the static ring 2 is set in the static ring seat 1, and the moving ring seat 4 and the static ring seat 1 are fixed on the base 12; The spring vibrator system composed of the vibrator 10, the elastic compone...
Embodiment 2
[0037] Refer to attached figure 2 :
[0038] figure 2 It is a structural schematic diagram of Embodiment 2 of the present invention. Its key technical requirements are basically the same as those of Embodiment 1, the main difference is that the static ring 2 in Embodiment 2 is fixedly installed on the static ring seat 1, and the moving ring 3 is flexibly installed on the moving ring seat 3, that is, the The above-mentioned moving ring 3 is flexibly connected to the moving ring seat 4, the moving ring 3 has only an axial degree of freedom, and the static ring 2 is fixed on the static ring seat 1.
[0039] The specific structure that restricts the moving ring 3 to only have the axial degree of freedom is: the moving ring 3 is provided with a third axial through groove, the moving ring seat 4 is provided with a third pin 14, and the third pin 14 is inserted into the In the third axial through groove.
Embodiment 3
[0041] Refer to attached image 3 :
[0042] image 3 It is a structural schematic diagram of Embodiment 3 of the present invention. Its sealing structure and key technical requirements are basically the same as those in Embodiment 1. The main difference is that the elastic element 7 in the spring vibrator system in Embodiment 3 is a large spring. The total stiffness of the small cloth spring.
