In addition, due to damage to the chemical pump piston seal and other failures, not only the continuity of the injection is affected, but also the process requirements for plugging. In order to improve the injection speed and plugging efficiency, conveniently control the injection speed, reduce the probability of equipment failure, ensure the continuity of the injection and the plugging process requirements, it is necessary to design a glue injection device for hydraulic structures in power stations.
