Embodiment Construction
[0020] The following is further described in detail by specific embodiments:
[0021] Reference numerals in the accompanying drawings include: piston ring 10 , circumferential groove 11 , magnet block 12 , balance hole 13 , positioning block 14 , support ring 20 , cylinder 30 , and piston 40 .
[0022] like figure 1 As shown, this figure is a simple exploded view of a long-life piston ring 10 sealing system of this embodiment. It mainly includes two parts, the piston ring 10 and the support ring 20 . A piston ring 10 and a support ring 20 form a sealing unit. The number of sealing units is multiple, and the structure of five sealing units is adopted in this solution. The piston ring 10 should pay attention to the selection of wear-resistant materials, while the support ring 20 is mainly made of materials with high thermal conductivity. choose.
[0023] The piston ring 10 is in the shape of a boss, and its surface is provided with a plurality of positioning blocks 14 . Th...
