In the operation system of hydropower stations, the condenser is mainly used to condense the steam discharged from the turbine into water. Through this process, the pressure at the turbine exhaust port is reduced, creating a highly vacuum environment, thereby improving the thermal efficiency of the turbine and allowing the steam to do work more fully. At the same time, the condensed water can be recycled and reused, achieving the circulation of water resources and ensuring the continuous and stable operation of the entire thermal cycle.

The installation of the condenser is a delicate and critical task, and the connection with the turbine exhaust port is of utmost importance. Before installation, the staff needs to conduct a comprehensive inspection of the condenser and turbine exhaust ports to ensure that all components are not damaged or deformed, and that the dimensional accuracy meets the design requirements. At the same time, a stable work platform should be built on the installation site, and various installation tools should be prepared, among which the screw jack is one of the core tools for achieving precise docking.

During the installation process, first use lifting equipment such as cranes to lift the condenser to the designated position near the turbine exhaust port and place it on a pre-set temporary support. Next, multiple screw jacks should be evenly arranged at the bottom of the condenser, and these screw jacks need to be strictly debugged to ensure that their lifting capacity and stroke are consistent. Then, the staff lifted the condenser slowly and steadily by synchronously operating the screw jack. During this process, high-precision measuring instruments such as laser rangefinders and level gauges are used to monitor the position and levelness of the condenser in real time. Based on the measurement data, precisely adjust the lifting height of each screw jack to gradually align the centerline of the condenser with the centerline of the turbine exhaust port, while ensuring that the horizontal deviation of the condenser is controlled within a very small range. After multiple meticulous adjustments and measurements, the precise connection between the condenser and the turbine exhaust port was finally achieved, laying a solid foundation for subsequent sealing and welding work, ensuring the safe and stable operation of the hydropower station.
