针对孤东油田聚合物分散装置传统的运行模式,利用变频器灵活可控的特性,设计改造了液位控制系统,使溶解罐液位在整个配制聚合物过程中始终保持在最佳液位,排液泵、搅拌机一直平稳运行,且不需要增加任何投资,改善了聚合物溶液的配置质量,取得了很好的节能降耗效果,是对现有聚合物分散系统运行的一次有效的技术改进。 Aiming at the traditional operation mode of polymer dispersing device in Gudong oilfield, the level control system is designed and improved by the flexible and controllable frequency converter. The liquid level in the dissolving tank is always kept at the optimal liquid level throughout the polymer preparation process. Drainage pumps and mixers have been running smoothly without any additional investment, improving the quality of polymer solution configuration and achieving good energy-saving and consumption-reducing effects. This is an effective technical improvement on the operation of existing polymer dispersing systems .
