AI Technical Summary

Technical Problem

Existing rotary compensators experience a decline in sealing performance and a shortened service life after the sealing packing wears down, and increasing the axial length of the sealing packing is not an effective method.

Method used

A long-life rotary compensator is designed, which adopts a structure of working unit and standby working unit. The use of sealing packing is switched by adjusting the preload, thereby extending the service life of the sealing packing.

Benefits of technology

This achieves wear sharing of the sealing packing, extends the service life of the rotary compensator by more than two times, and improves the stability and durability of the sealing performance.

Abstract

一种长寿命旋转补偿器,用来补偿的管道热胀冷缩。其包括第一外管(3),第一外管中插有内管(11),内管与第一外管之间设有第一密封填料(5),第一密封填料的右侧设有第一压套(7),第一压套的右侧面上密封连接有第二外管(8),第二外管与内管之间设有第二密封填料(9),第二密封填料右侧设有第二压套(10)。采用上述结构,可以使第一压套对第一密封填料的压力远大于第二压套对第二密封填料的压力,第一外管与内管之间密封;正常运行时,第一密封填料发生磨损,而第二密封填料磨损很小或不磨损;当第一密封填料失效后,手动调节增大第二压套对第二密封填料的压力,使第二外管与内管之间密封。大大提高了旋转补偿器的使用寿命。
