China has successfully developed the largest single-capacity air-cooled turbo generator
The development of the excitation transformer for the Xia Hydropower Station is a super-large project. The hydropower generating unit of the Xia Hydropower Station is also the largest unit in the world. It has high requirements for the excitation transformer to suppress harmonics in the inrush current. Shunde Special Transformer Factory In the development process of epoxy cast dry excitation transformers, many domestic and foreign excitation system manufacturers such as Harbin Electric Machinery Factory Dongfang Motor Factory Nanrui Group, etc., and foreign six 88 Siemens companies participated in the research and development of prototypes. All the excitation system manufacturers of the company have a better understanding of the technical level of the manufacturing capacity of the Shunde Special Transformer Factory. Therefore, the German Siemens Transformer Factory is a partner and subcontracted to manufacture the excitation transformer.
In May of this year, with the evaluation results of experts and the approval of relevant departments, 14 sets of excitation systems in the auxiliary system of the Xia'an left bank power station were won by Siemens AG of Germany, and 14 sets of epoxy cast dry excitation transformers were manufactured by Shunde Special Transformer Factory.
The successful development of the domestic super large generator set excitation transformer and the bidding of the Xia'an left bank power station indicate that China's epoxy cast dry-type transformer technology has entered the international advanced level, and is also a large-scale hydro-thermal power unit and nuclear power unit in the development of China's electric power industry. China's development of the largest single-capacity air-to-air-cooled steam turbine generator Shandong Power Generation Equipment Factory trial production success China's first technology is the latest. The performance is optimal. The 135,000-kilowatt air-cooled steam turbine generator with the highest technical capacity and the largest single-unit capacity is used as a test sample for the introduction of the 102-megawatt-class air-cooled steam turbine generator project in Switzerland. The performance indicators have reached the design requirements of ABB, and have been recognized by ABB Shandong Electric Power Materials Corporation and the supervisory party Shandong Electric Power Research Institute and the user Dongliyan Power Plant.
The air-cooled generator has a simple system compared with the hydrogen-cooled water-cooled unit. Excellent technical performance, safe and reliable power station auxiliary equipment, less installation and maintenance. Low operating costs. The successful trial production of 13.5 million kilowatts of new products has brought the capacity and technical level of China's air-cooled steam turbine generators to a new level.
High Pressure Washer is a machine that rushes a surface by using a power plant to generate high-pressure water from a high-pressure piston pump. It can peel off the dirt and wash it away to clean the surface. Because it uses high-pressure water column to clean dirt, high-pressure cleaning is also recognized as one of the most scientific, economic and environmentally friendly cleaning methods in the world.
Can be divided into cold water high pressure cleaner, Hot Water High Pressure Cleaner, motor driven high pressure cleaner, gasoline engine driven high pressure cleaner. The difference between the two is that the hot water washer adds a heating device to heat the water using a combustion cylinder or an electric heating device. However, hot water washing machines are expensive and costly to operate (because diesel or electricity is used to heat water), but many professional customers will choose hot water washing machines.
According to the drive engine, there is electrical high pressure cleaner, gasoline high pressure cleaner and the diesel driven washer. As the name implies, all three washing machines are equipped with high-pressure pumps, which are completely portable and lightly moved. They are connected to a motor, a gasoline engine or a diesel engine, respectively, thereby driving the high-pressure pump to operate. The advantage of a gasoline engine driven high pressure cleaner and a diesel driven washer is that they can work in the field without the need for a power source.
Industrial high-pressure cleaners are divided into three categories according to their use, household washer, commercial washer and industrial washer. First, the home use high-pressure washing machine, customer need it portable, flexible, easy to operate. Second, the commercial high-pressure cleaner, which has higher requirements on parameters and frequency of use.
