Pump Surge Control Valves and Intermittent Power Failures an Often Overlooked Threat to Pipelines 泵喘振控制阀和间歇性电源故障是管道经常被忽视的威胁
发布日期: 2005-06-17
泵喘振控制阀是大多数泵站和水泵的普遍特征 抽水站。由于大多数抽水站都是向高位蓄水库抽水,一些 在变频控制驱动器中发现的新功能,从费用上来说,通常不是 适用于不需要流量变化的系统。我们的目标是 把水排到分配系统中,然后装满水箱,或者根据需要处理这些需求 尽可能高效、迅速地完成。然而,需要从最初开始 在大多数标准电机中,泵和电机瞬间全速启动的力 控制并通过一个缓慢的管道将流量缓慢地引入分配系统 开启控制阀在水中是一种备受尊敬、由来已久且常见的做法 世界各地的系统。本文提供了标准泵喘振的折线图 控制集成到标准电机控制中。本文初步探讨了 隔膜控制阀,但在四分之一转操作器开启的问题上有相似之处 球阀和蝶阀也用作泵喘振控制器。包括数字。
Pump Surge control valves are ubiquitous features of most pump stations and pumping plants. Because most pumping plants are pumping to elevated storage, some of the new features found in variable frequency control drives are often, by expense, not appropriate for such systems where variations of flow are not needed. The goal is to get that water out to the distribution system and fill that tank or take care of that demand as efficiently and as expeditiously as possible. However, the need to take the initial starting force of a pump and motor starting instantaneously to full speed in most standard motor controls and slowly introduce that flow to the distribution system through a slowly opening control valve is a well respected, time honored and common practice in water systems throughout the world. The paper provides a line diagram of a standard pump surge control integrated into a standard motor control. This paper deals initially with diaphragm control valves but there are similarities in issues with quarter turn operators on ball and butterfly valves employed as pump surge controllers as well. Includes figures.
