Problems solved by technology
However, for on-site dynamic balancing work, it needs to be installed through the round hole on the cylinder. It is very difficult to use the slide-in installation method. If there is already a dynamic balance block in the dovetail groove, it cannot be slid to the designated position.
In addition, the use of a dovetail-shaped dynamic balance block will bring some problems. Because the weight of a dovetail-shaped dynamic balance block is relatively light, it is usually necessary to install multiple pieces, and the dynamic balance block needs set screws, which virtually increases the risk.
In addition, since there is no special tool for installation, if the temperature of the rotor is too high, people should not approach it, which will prolong the installation time of the balance weight

The invention provides an installation tool for dynamic balancing blocks of steam turbine rotors and a use method of the installation tool. A tool body is composed of a hollow handle and an assembly sleeve connected to the front end of the hollow handle, the assembly sleeve is provided with a square containing cavity matched with dynamic balancing blocks in width, a screw via hole corresponding to a set screw installation hole is formed in the middle of the bottom face of the square containing cavity, and positioning holes are formed in the outer side of the screw via hole. A positioning rod is arranged in the hollow handle and the positioning holes in a penetrating mode. A screwdriver for screwing is arranged in the hollow handle and the screw via hole in a penetrating mode. The installation tool is simple in structure, convenient to operate, high in installation reliability, low in requirement for the practical operation capability of an operator and high in applicability and generalizability.
Description
technical field [0001] The invention relates to an installation tool for a steam turbine rotor dynamic balance block; [0002] The invention also relates to a method for using the steam turbine rotor dynamic balance block. Background technique [0003] During the operation of the steam turbine rotor, it is often affected by unbalanced forces. In order to ensure the safe operation of the unit, a high-speed dynamic balance test must be carried out before the rotor leaves the factory. In the design process, there are often balance holes for dynamic balance in the factory. Taking the domestic 100MW low-pressure rotor as an example, there are dovetail grooves at both ends of the low-pressure rotor to facilitate the installation of mass blocks for dynamic balancing. After passing the dynamic balance in the factory, it can ensure that the unbalanced amount of the rotor is within a certain range. [0004] However, with the long-term operation of the unit, sometimes the vibration...
