| 中文摘要: |
| 总结分析出双模硫化机地沟支管道的短期损坏原因是由高速水流冲刷造成的。介绍了本公司采取的几种改善措施，即在每根通向硫化地沟支管道的阀门前端增加1个缓冲罐，调整硫化热水回收时间，在冷却水、动力水、抽真空排水、总排水的回水管道中增设1个倒U形弯头，取得了成效。以LL-B1320/2895×2双模硫化机为例，改进后每次多回收平均温度为120 ℃的热水93.4 kg，每天硫化22次，可减少热量损失6.07×105kJ，折合压力为115 MPa的蒸汽217 kg，折合17.36元，一年运行300天，1台双模硫化机一年仅靠增加热水回收量一项就可使生产成本减少5 208元。 |
| 英文摘要: |
| It is concluded from the analysis that the premature failure of the by-pass for twin press underground pipeline is caused by the rush of the high speed water flow. Some effective precautions include:a)adding a buffer tank in front of every valve to the by-pass for twin press underground pipeline；b)adjusting the recycling time of hot curing water；and c)adding a reverse U-shape elbow in the back water pipe for cooling water，hydraulic water，vacuum pumping water and main drain. Taking LL-B1320/2895×2 twin press as example，93.4 kg more of hot water at 120 ℃ are recycled in every curing cycle of a press after the modification，i.e. 5 208 RMB yuan·a-1 are saved. |
