本文从我国油库的实际情况出发,简要论述了用泵发油工艺中为了克服管路水击所应采取的技术措施,并着重讨论了安全阀的选用和空气缓冲室的容积计算问题。作者根据流体力学的基本原理,在分析“水击”产生过程的基础上,推导了空气缓冲室容积计算的基本公式,并举例加以应用。 This paper starts from the actual situation of China’s oil depot, briefly discusses the technical measures that should be taken to overcome the water hammer in the process of pumping oil, and focuses on the selection of the safety valve and the calculation of the volume of the air buffer chamber. Based on the basic principles of fluid mechanics, based on the analysis of the “water hammer” generation process, the author deduces the basic formula for calculating the volume of the air buffer chamber, and gives an example for its application.
