Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] refer to Figure 1 ~ Figure 4 , a mechanical seal end face structure of a variable-depth spiral T-shaped groove, including a moving ring and a static ring of a mechanical seal, one side of the end face of the moving ring or the static ring is the high-pressure side, that is, the upstream, and the end face of the moving ring or the static ring The other side is the low-pressure side, that is, the downstream side. A series of variable-depth spiral T-shaped grooves 1 are arranged on the end surface of the moving ring. Sealing weirs 2 are arranged between the variable-depth spiral T-shaped grooves 1. The variable-depth spiral T-shaped grooves 1 It communicates with the circumferential ring groove 3, and a sealing dam 4 is arranged between the circumferential ring groove 3 and the downstream side.
[0025] The number of the variable-depth spiral T-shaped grooves is ...
