摘要
封隔器的封隔密封性能除了与其密封元件有关外,还受其锁紧装置的性能制约。锁紧装置的坐封回弹距离、锁紧防退能力均直接决定了封隔器的环空封隔能力与密封的长久可靠性。着重分析了几种典型的封隔器锁紧装置,从锁紧装置的回弹距离、锁紧承载性能等几个关键点进行了深入分析,为封隔器设计提供一定的参考依据。
In addition to the packing element, the performance of a packer is largely influenced by the retainer. The retainer＇s rebound distance and locking ability directly determine the packer＇ssealing abilily and working reliability. The analysis is made for some typical retainers,studied rebound distance and locking ability,so as to provide certain references for the design of packer.
