Industrial Steam Turbine

Industry steam Turbine and generator: 1,Meeting various parameters of steam admission and extraction.According to user's requirement to choose and design steam turbine. Many speed types can be chosen.the main mover in the thermal power plant. 2,Applicable to self-supplied power plant and regional thermal electric plant that not only need electric power but also adjust thermal load in a large range such as thermal electric power, cheemical industry,sugar-making,paper-making,textile,food industry. 3,Supply electric power and industrial steam,with electrc and thermal load adjusted respectively. 4,Reasonable and compact structure,easy to install,operating steadily and reliably. 5,Adopting DEH and full hydraulic governing system. 6,Designed to drive various shift machines such as water pump,compressor and blast bowler. Steam Turbine is a kind of external combustion rotary machinery which can convert steam thermal energy into mneed electric power but also adjust echanical work. After steam from boiler enters into steam turbine, it passes a series of ring type of nozzle and movable blades by sequence, which converts thermal energy of steam into the rotating mechanical energy of steam turbine rotor. Steam in turbine converts energy in different way, constituting steam turbine with different working principles. Traditionally, the components and system of steam turbine is divided into three categories: turbine proper, governing system and auxiliary equipment. Turbine proper: include casing, rotor, diaphragm, blade etc. Governing system: include pedestal of bearing, bearing, regulator, steam inlet valve etc. components, control oil system and lubricating oil system etc. Auxiliary equipment: include condenser, HP and LP heater, extractor etc. and return heating system, shaft sealing system and vacuum extraction system etc. Steam Turbine adopts advanced fully 3D flow passage design technology, reasonable structure, and excellent performance. Regulation and control of steam turbine adopt whole hydraulic control system or electro hydraulic control system, meanwhile equipped with different function of safeguard devices, which guarantees safe and reliable operation of steam turbine. Steam Turbine is mainly divided into condensing type of steam turbine, extraction type of steam turbine, back pressure type of steam turbine, and extraction back pressure type of steam turbine etc. Generator Base on different working principles, generator can be divided into DC Generator, Asynchronous Generator and Synchronous Generator. At present, most large scale Generators are all Synchronous Generators. The three phase Synchronous Air Cooling Generators mated with a lot of Steam Turbines and Gas Turbines, capacity from 1500KW to 15000KW, air cooled, adopt AC brushless excitation with permanent excitation auxiliary exciter, and are equipped with digital high accuracy automatic voltage regulators. It also could adopt co-axial DC excitation or static excitation. Generator consists of stator, rotor, bearing, cooling system and excitation system. Many generator partner factories of our company have advanced testing method, and a lot of advanced testing equipment, which can satisfy the requirements of raw material acceptance and product manufacturing process, meanwhile, can also meet the demands of developing new products and implementing all kinds of technical research. Generator manufacturing adopts advanced machining equipment, including imported CNC six-shaft insulation package machine, VPI full immersion equipment, slot milling machine for rotor, CNC lathe, silicon steel sheet, deburring machine and other key processing equipment. For satisfying whole performance test of Generator, large professional generator test station are equipped to take the Generator Ex-Factory Test, which will ensure comprehensive performance test.
