Zibo Zhuoxin steam turbine Co., Ltd.   

Company is mainly engaged in turbo generator installation, debugging, the old and the new unit sales, processing and supplying AC and DC motor maintenance and spare parts. The company is engaged in the research on steam turbine manufacturing more than forty years of senior engineers and senior technicians, repair motors thirty years of composition, equipment processing capacity has a strong technical force and high. Have to undertake reform, turbine engineering many large enterprises overhaul, the market radiation throughout the country, have a good reputation in the customers. We mainly undertake repair: steam turbine, steam turbine fittings, steam turbine, steam turbine, steam turbine maintenance overhaul transformation services. Steam turbine main oil pump and the overspeed trip mechanism. All rotors are finished, and all the blades in the assembly, the tests carried out at full speed and accurate dynamic balancing. Package: impeller, shaft sleeve rotor, coupling and other parts are processed, heat set in step type main shaft. Between the various components and the spindle by interference fit, to prevent the impeller loose caused by centrifugal force and temperature effect, and key to transmit torque. Low pressure steam turbine low pressure rotor rotor and high pressure turbine often adopts the suit structure. Set the rotor at high temperatures, the impeller and the main shaft is easy to loose. So should not be used as high temperature steam turbine high pressure rotor. Rotor: impeller, shaft sleeve, coupling component and the spindle is composed of a whole forging cut into, no heat sleeve, which solves the problem of impeller and shaft connection is easy to loose under high temperature. High, medium pressure rotor of the rotor is used for large steam turbine. Compact structure, the startup and variable condition adaptability, suitable for high temperature operation, good rigidity of rotor, but forging, machining requirements are high, long processing cycle, it is difficult to guarantee the quality of large forgings. Welded rotor: low pressure steam turbine rotor mass, the centrifugal force to bear, the sheathed rotor impeller bore at run time will occur large elastic deformation, so it needs to design a large assembly interference, but it will cause a great assembly stress, if the rotor, it is difficult to guarantee the quality, so the sectional forging, welding rotor welding combination. It is mainly composed of a plurality of impeller and shaft assembly and welding. Welded rotor forgings of small, light weight, compact structure, high bearing capacity, compared with the rotor with the same size, with a central hole rotor welding, high strength, good rigidity, light weight, but for the welding of high performance requirements, the application of this rotor by welding process and test methods and materials limited. Combined rotor: by integral structure set structure, combines the advantages of two kinds of rotor.
