摘要:
为了解决斯里兰卡阿塔纳地区的供水紧张问题，按照中国相关工程标准援助建设了阿塔纳净水厂，配套建设了大型岸边式取水泵站。介绍了取水泵站工程的工艺设计，从水泵效率、占地、机电投资、防洪等角度考虑，取水泵采用立式长轴离心泵; 结合大变幅水位及藻类暴发期等因素确定预处理方案，采用旋转格网过滤预处理工艺，采用转鼓过滤器作为高藻期预除藻措施；通过定速泵与变频调速泵搭配运行方式适应泵组不同供水量情况；对事故停泵下引起的停泵水锤进行水力过渡计算，结合实际情况选择管路空气阀+泵后空气阀+支路泄压阀作为防护方案，优化了取水泵站的运行条件。
Abstract:
In order to solve the problem of water shortage in Attanangalla area of Sri Lanka, China assisted in construction of Attanagalla waterworks and a riparian type water intake pumping station, which were in accordance with relevant engineering standards of China. Process design of intake pumping station was introduced. The vertical long shaft centrifugal pump was adopted from the perspective of pump efficiency, land occupation, electromechanical investment and flood control. Rotating grid filter and rotary drum filter were used as pretreatment equipment considering large amplitude water level and algae outbreak. Through matching operation of the constant speed pump and variable frequency speed pump, it can adapt to different water supply conditions of pump group. The hydraulic transition calculation was conducted, which was calculated for water hammer caused by pump stop accidentally. Operation conditions of intake pumping station were optimized according to “pipeline air valve + air valve after pump + pressure relief valve”, which were selected as water hammer protection facilities.
