Considering the water damping free vibration frequency calculation has also done some work. And test verification in hydrostatic conditions. Calculation of the vibration frequencyare included in the contents of the relevant professional and technical personnel. The shaftis considered in the calculation of water quality and its rotation axis, the translational motion, the result is more accurate. In the non design condition and transient condition,alternating load component random will achieve considerable value, may cause thedestruction of parts of the fatigue.

Detection technology is an important means and technical support for quality control.Tokyo Electric Power Company is the first national level measurement units, but also thefirst implementation of the 15010012 "quality assurance requirements" standard test equipment, and achieved certification units in Sichuan's first.

We establish the effective operation of the system and a set of scientific metrology confirmation. Meet the needs of production and scientific research, Shandong precision pipe developed 20m laser length measuring machine, large diameter and high precisiondiameter measuring ruler, blade special measuring tools, precision is up to 0. 5% the conductivity of metal material tester, 90MW nuclear power base center aligning instrumentfor measuring equipment or apparatus. Physical and chemical inspection, a computer-aided detection and management system, to carry out field failure analysis of metal material and high cycle fatigue, stress corrosion, fracture analysis of the. To carry out a variety of testing object detection methods and acceptance criteria of nondestructive testing, especially the UT test runner blade weld.

Measurement of thermal, successfully developed a test station electrical, thermal,mechanical, computer data acquisition and data processing system of turbo generatoroverspeed, including test status monitoring and fault protection. DC test station, governorand excitation test station has also made the CAT content and degree of differenttechnological transformation.

Manufacturing technology is the modern civilization birth attendant, no matter whatcivilization or advanced technology through products can be shown, and make theproducts by manufacturing technology. The main features of modern manufacturing technology is a high precision, high efficiency, low cost. Our seven years of process workvery seriously, has achieved remarkable results.

The door of NC machining technology of NC machining is the key of East electricmanufacturing technology development, the company now has more than 60 sets of CNC machine tools. Widely used in the model of blade runner, axial flow type and the mixed flowfield of blade, guide vanes, guide vanes in the hole, the wind turbine generator, rotor slot wedge copper leaf, milling, stamping die, die, die line up, pole plate, wear plate of the turbine, a variety of seal plate processing, crown, ring the runner chamber, cone, such astwo-dimensional surfaces.
