Abstract

Water hammer is inevitable in pressurized pipeline water delivery projects. Gasbag-type pneumatic tanks are more reliable and economical than other water hammer protection measures in the high-lift water delivery projects with medium-and-small flow. Based on the actual project, the commercial software Bentley Hammer was applied to analyze the hydraulic transient process of the water delivery pipeline. The water hammer protection result was studied when the combination of the gasbag-type pneumatic tank, multi-function water pump control valve and air valve was used, and the impact of the volume and preset pressure of the tank on the result of water hammer protection was explored. Numerical simulation models for three cases were constructed through the Bentley Hammer software, where no protective measures were used, the combination of multi-function pump control valve and air valve was used, and the combination of multi-function pump control valve, air valve and gasbag-type pneumatic tank was adopted respectively. Hydraulic transient process analysis was performed when the three pumps stopped simultaneously. The research results showed that the installation of gasbag-type pneumatic tank in high-lift water delivery project with medium-and-small flow can achieve good water hammer protection result. For the overall water delivery pipeline system, the water hammer protection ability of the gasbag-type pneumatic tank increases with the increase of the volume and the preset pressure of the tank. Appropriate volume and preset pressure of the pneumatic tank can effectively control the maximum positive and negative pressure of water hammer in the pipeline and help to achieve the optimal social and economic benefits.
