胶球清洗装置

2.胶球的回收及更换： 关闭气动阀1，胶球便在装球室内积聚，5分钟后停止 胶球泵并关闭气动阀2。 2.Reclaim and replacement : Closing the pneumatic valve 1, the rubber balls will accumulate in the ball room. You can stop the rubber ball pump and close the pneumatic valve 2 in 5 minutes.
该系统设置两个相同的独立回路，各自清洗对应的凝 汽器内的管子。每个回路包括胶球泵、装球室、收球网、 胶球分配器、阀门及管道。 The system arranges two independent loops cleaning their own tubes in the condenser. Each loop includes rubber ball pump, ball room, strainer , rubber ball dispenser, valves and pipes.
系统简介 Overview of The System
胶球清洗系统采用直径略大于凝汽器管子内径的海绵胶 球。在循环水压力的作用下，通过胶球与管子内径之间的 摩擦，来清洗管子内壁，以维持凝汽器管子的清洁度，从 而保证凝汽器管有较高的热交换效率。 The diameter of the sponge rubber ball is slightly larger than the condenser tube’s in the sponge rubber ball on-load cleaning system. Under the pressure of the circulating cooling water, It uses balls to clean the inside surface of condenser tube bundles continuously through rubbing each other, to ensure condenser tubes having a higher heat exchange efficiency.
备注：胶球在使用前应浸泡8-12 小时。 Note: Rubber balls should be soaked in 812 hours before using.
Thank You!
• What method do you use for cleaning the condenser tubes? • We use a “sponge rubber ball on-load cleaning system”. It uses balls to clean the inside surface of condenser tube bundles continuously. • We are interested in such a kind of on-load cleaning system. Would you explain it to us in details? • The balls will be injected into the CW (circulating water) inlet piping by means of a special pump and distributors, recycling a small amount of balls in the CW. • How much is the dynamic head of BFP? • After passing the condenser, the balls will be automatically removed from the CW by means of a strainer located in the CW outlet piping, and then the balls will be diverted by a recycle pump and collector which will then reinject them into the CW inlet.
工作顺序
The Order of Operation
1. 先后开启胶球泵和气动阀2，从收球网侧面来的循环水经 胶球泵送出后，通过装球室、气动阀2和胶球分配室进入 循环水进水管道，以建立水流循环3分钟以上。随后开启 气动阀1，胶球经气动阀1进入循环水进水管道，开始清洗 管道，并经收球网回收后重新进入装球室。如此循环，已 达到清洗清洗管子的目的。 1.First,opening the rubber ball pump and pneumatic valve 2, the circulating cooling water coming form the side of the strainer flows through the rubber ball pump, the ball room, the pneumatic valve 2 and the rubber ball dispenser into the circulating cooling water pipeline, then sets up the circulation more than 3 minutes. After that, openning the pneumatic valve 1, the rubber balls began to clean the pipes when the balls flowing into the circulating cooling water tubes, and the balls goes into the ball room under the function of the strainer . In this way, the tubes are cleaned.
