China's most high-speed thrust bearing test stand was recently built and put into use in Deyang City, Sichuan Province. This marks that China's bearing test platform has leapt to a new level, and it can meet the needs of large-scale, high-level testing of hydro-generator thrust bearing. This high-speed thrust bearing test bench built by Dongfang Electric Corporation Dongfang Motor Co., Ltd. fills the gaps in our country's long-term lack of high-speed thrust bearing test rigs, and has full independent intellectual property rights.
High-speed thrust bearing test platforms have been an important test tool for the research and manufacture of various electrical equipment. The original bearing test stand of Dongfang Motor Company was built in 1986. Its maximum speed is only 360 rpm, and it can only carry out a 1,000-ton hydroelectric generator thrust bearing model test. It is far from being able to adapt to large-scale domestic and international hydropower equipment research. Manufacturing requirements.
The company's scientific and technical personnel began designing in January 2010 and through technical research, it took over one year to build the first high-speed thrust bearing test bench in China. This bearing test stand can reach a maximum speed of 750 rpm, a maximum load capacity of 2,000 tons, a maximum test bearing diameter of 2800 mm, and a drag motor power of 4500 kW. The drive system consists of an AC motor and a high-voltage inverter. , using a test and control of all-digital flexible measurement and control system. This test platform is capable of performing 6,000-tons of mega-hydro turbine generator thrust bearing model tests and full-scale bi-directional thrust bearing full-scale simulation tests of pumped-storage generating units, fully able to meet the test requirements for millions of kilowatt-class turbine generator thrust. It can also meet the need for large-scale development of two-way high-speed thrust bearings for pumped storage units.
