Natural frequency calculation considerations damping water also did some work. Under hydrostatic conditions and experimental verification. Excitation frequency of the calculation is included in the study content related professional and technical personnel. Shaft calculation takes into account the quality of its rotational effects, the translational movement of the axis of the body of water, make the results more accurate. In the off-design conditions or transition conditions, random alternating load components will reach considerable magnitude, it may cause fatigue damage components.

Detection technology is an important means of quality control and technical support. Tepco is the first national-level units of measurement, but also the country's first batch of the implementation of "quality testing equipment to ensure that the requirements of" 15010012 standard and obtain certification in Sichuan, the first unit.

We have established a set of scientific and effective running of the metrological confirmation system. With production and research needs, Shandong precision pipe developed a 20m laser measuring machine, the inner diameter of the large-diameter high-precision measurement scale, big wicket special measuring accuracy up to 0.5% of the metal material conductivity meter, 90MW nuclear outer housing Center alignment measuring instrument, such as special equipment or appliances. Physical and chemical testing, the establishment of computer-aided detection and management systems, to carry out field failure analysis of metallic materials and high-cycle fatigue, stress corrosion, fracture analysis of research work. Non-destructive testing methods and acceptance criteria carried out studies testing various detection objects, especially runner blades UT weld inspection.

Electrical measurement, thermal aspects of successful development of the turbogenerator speed test station electrical quantities, the amount of thermal and mechanical amount of computer data acquisition, data processing systems, including monitoring and fault protection test status. DC test station, the governor and excitation test stations have carried out different aspects and levels of CAT transformation.

Manufacturing technology is spawning woman modern civilization, no matter what culture or technologically advanced products can be manifested by, and make the product by the manufacturing technology. Mainly modern manufacturing technology is high-precision, high efficiency, low cost. For seven years we have attached great importance to the process, achieved remarkable results.

Doors CNC machining CNC machining technology is the East power manufacturing technology development focus, the company now has more than 60 sets of CNC machine tools. Widely used in the model runner blade, axial and mixed flow real machine blades, vanes, guide vane shaft hole, turbine generator blades, wedges, rotor copper milling holes, dies, wire mold, mold pan processing pole plate, turbine wear plate, various sealing plate, the crown and lower ring, discharge cone, runner chamber and other two-dimensional surface.
