The invention relates to the technical field of nuclear power station steam turbines, and discloses a steam turbine rotor dynamic balance processing method and device. The method comprises the following steps: acquiring an old blade unbalance amount and an initial unbalance amount of a rotor; wherein the unbalance amount of the old blade comprises the unbalance amount of the front-side old last-stage blade and the unbalance amount of the rear-side old last-stage blade; wherein the initial unbalance amount comprises an initial first-order unbalance amount and an initial second-order unbalance amount; obtaining return-to-zero weight of the new blade according to the unbalance amount of the old blade; wherein the zeroing weighting of the new blade comprises zeroing first-order weighting and zeroing second-order weighting; and determining the unbalance amount of the new blade according to the initial unbalance amount and the return-to-zero weight of the new blade. According to the dynamicbalance processing method, the dynamic balance processing efficiency of the steam turbine low-pressure rotor is improved, and manpower and material resources are saved; and the problem of high rotor vibration caused by unbalanced mass in the starting stage of the steam turbine is avoided.
Description
technical field [0001] The invention relates to the technical field of steam turbines in nuclear power plants, in particular to a method and device for dynamic balancing of steam turbine rotors. Background technique [0002] A steam turbine is a rotating machine powered by steam and converts the thermal energy of steam into mechanical work. It is the most widely used prime mover in modern thermal power plants. When the steam turbine is working, the high-temperature and high-pressure steam passes through the fixed nozzle to become an accelerated airflow and then sprays onto the blades, which makes the rotor equipped with blade rows rotate and work externally at the same time. Usually, during the overhaul of the steam turbine, the last-stage blades of the steam turbine rotor will be replaced. The replacement of the last-stage blades of the rotor will cause the balance state of the rotor to change accordingly, and the change in the balance state of the rotor may cause the vibra...
