| 中文摘要: |
| 分析了影响轮胎硫化动力站除氧热水装置出口热水温度的各种干扰因素,提出了原控制系统的部分不足之处,对原控制系统进行了实质性的改进,改进后可迅速克服进入副回路的管网蒸汽压力和补水流量的干扰,精确控制除氧器出口热水温度,改善了主调节器GC1的广义对象的特性,同时,改进后的系统允许副回路各环节的特性在一定范围内变动而不影响整个系统的控制质量,也可以减少因阀门流量特性不合适而造成的副效应。 |
| 英文摘要: |
| The various affecting factors on the hot water temperature at the outlet of hot water deoxidizing device in tire vulcanization power station were analysed , the shortcoming of the original cont rol system was proposed , and a significant modification was made. The interference with the pipenetwork steam pressure and complimentary water flow into the by-pass was eliminated by the modification ,the generalized object characteristics of the main adjuster GC1 improved ,the technical parameters in different part s of by-pass were allowed to be changed in a certain limits without affecting the control quality of whole system ,and the negative effect resulting from the unsuitable valve flow was reduced. |
