摘要
在分析常规密封盘根的密封机制,及其存在的形状和材质选用不合理、更换不便、密封效果不好和使用寿命低等问题的基础上,提出了采用普通传动V带作为新型密封盘根的设计方案。在现场试验的基础上,分析了新型密封盘根的密封机制,给出了盘根的设计计算方法,并将新旧盘根的现场使用情况进行了对比与分析。结果表明,新盘根的使用节约了生产成本,改变了盘根的密封方式,实现了抽油机不停机加盘根作业,降低了劳动强度,具有良好的推广前景。
The sealing mechanism of conventional sealing stuffing was analysed.Aimed at the disadvantages of the conventional sealing stuffing,such as the unreasonable selection of its shape and material,being inconvenient for the replacing of it,bad sealing effect,and low service life,the design adopting ordinary transmission belts of V shape as new sealing stuffing was presented.Based on the field tests,the sealing mechanism of new sealing stuffing was analysed,and the design and calculating method of stuffing was d...
