随着变频技术的不断深入,变频器在生产中使用得越来越多。其卓越的调速性能,能够更好地满足于石化企业生产装置不同工艺要求的需要。变频器的普遍使用,既满足了生产要求,又节约了能源。以燕化公司化工六厂高压聚乙烯装置主挤压机控制系统由原有的直流调速控制改为交流变频调速控制为例,论述了石化企业挤压机电动机及控制的更新改造,从而实现了设备国产化、节能化及控制简洁化。
With the constant deepening of frequency conversion technology, frequency converters are used more and more in production. Its excellent speed performance, to better meet the requirements of different petrochemical plant production process equipment needs. The universal use of frequency converter, not only meet the production requirements, but also save energy. Taking the main extruder control system of the high-pressure polyethylene plant of the chemical company No.6 of Yanhua Company changed from the original direct current speed control to the alternating current variable frequency speed control as an example, the renewal and modification of the extruder and control of the petrochemical enterprise extruder were discussed Achieved the localization of equipment, energy-saving and simple control.
