As a high-precision and heavy-duty power equipment, gas turbines have extremely strict requirements for positioning accuracy and load-bearing stability during the installation stage. The screw jack, with its unique structural advantages and performance characteristics, has become the core auxiliary tool in this stage, providing key support for the safe and efficient advancement of installation work.

The core function of a screw jack is precise load-bearing and height adjustment. The core components of gas turbines, such as rotors and cylinder bodies, can weigh several tons to tens of tons. During installation, the components need to be smoothly lifted to the designated position and then fine tuned with millimeter level accuracy. Spiral jacks rely on the principle of spiral transmission, with strong load-bearing capacity and smooth lifting without obvious rebound phenomenon. They can stably lift heavy components and achieve height adjustment through rotation adjustment to ensure accurate docking of components with installation benchmarks and avoid equipment damage caused by positioning deviation.

During the installation and alignment process, the screw jack can provide multi-point collaborative support. The installation of gas turbine components requires ensuring levelness and coaxiality, and a single support point is difficult to meet the balance requirements. By arranging multiple screw jacks reasonably, components can be lifted from different directions, adjusting the height of each point, quickly calibrating the horizontal state and axis position of the components, greatly improving alignment efficiency, and reducing project delays caused by repeated lifting.

In addition, the screw jack has good self-locking performance, which can maintain the load-bearing state without loosening in emergency situations such as power failure and gas interruption, providing reliable safety guarantee for installation operations. Its compact structure and convenient operation can adapt to the narrow space requirements of gas turbine installation sites. When used in conjunction with pads, it can further enhance stress stability and effectively protect the equipment base and ground from damage. In summary, the screw jack is a key tool for ensuring accuracy, safety, and efficiency in the installation of gas turbines, highlighting the important value of auxiliary equipment in the installation of heavy precision equipment.
